Part 7: Model of Construction Waste Treatment Plan

Keywords: municipal roads; Subgrade; Construction waste; Treatment and utilization;

CLC No.: TU99 Document ID No.: A

In road engineering construction, it is often encountered that construction waste is buried deeply along the proposed road. Some are formed by demolition and dumping during urban development in recent years, and some are formed by accumulation over decades in urban development. In the face of a mountain of reserves of tens of thousands of cubic meters or even up to 100000 cubic meters, the cost of all pulling and running is staggering, and this part must be balanced and utilized in combination with the design line position and elevation. However, how to use these construction wastes to achieve stable and reliable subgrade is still difficult to find a standard model. In the actual construction application, improper utilization and disposal methods of construction waste have resulted in cracks, pits and other damages to the pavement after short-term operation. The actual reason is that the use of construction waste to build subgrade does not meet the standard requirements and there are quality problems, resulting in serious consequences and huge losses. Therefore, it is necessary to make deep research, summary and demonstration based on the actual situation of waste utilization in the construction of urban municipal roads, so as to accumulate more scientific, reasonable and mature methods in this regard, ensure the construction quality of roads, and reflect higher benefits.

1、 Instance Background

The brave lung of Han Dynasty and Dong Dynasty in Xi'an is located in the area where the people of Han Dynasty and Dong Dynasty are living. It is the combination of brave punishment of Han Dynasty and Yong Dynasty's support for pottery. It is a traffic artery, landscape avenue, and ecological avenue in this area, and is the first of the Kangmu Memorial Tomb of Han Dynasty, Youfeng, Xianwei Cave Project. The road in this construction section starts from Changle Road in the south and ends at Huaqing Road in the north. The total length of the road is 2162.761m, the width of the carriageway is 22m, the design of a single two-way four lane road, and the width of the red line is 50m. There is one overpass bridge and one underpass box culvert along the line. Regional importance is very important. The project includes roads, rainwater and sewage.

According to the design data, the surface garbage soil within the scope of the road works is deep, the maximum thickness is 7m, and it is loose. According to the observation of the side walls of the rainwater and sewage ditches excavated at the construction site, the surface along the line is deeply buried with garbage, with a maximum depth of 8.5m, and the composition and density are different. According to the investigation, this line was originally the riverbed on the left bank. The current ground in the river embankment was formed after the 1980s. It was formed by the dumping of construction waste and domestic waste in urban and surrounding rural areas for many years, with different composition and large burial depth.

Therefore, the disposal of deep buried garbage along the road has become a key point of road construction, and the key to ensure the subgrade quality and the final road design and construction success or failure.

2、 Treatment scheme

First, select a 600m test section for operation, and the parties involved in the construction negotiate to determine that 1.0m of waste soil under the roadbed should be replaced, 3.0m of some chicken house shaped waste pits should be replaced, and 0.4m of the upper part of the replacement should be filled with plain soil. Since the compactness of construction waste soil cannot be detected, the subgrade filling is mainly controlled by relevant parameters to ensure the application effect of this method. Key parameters are: virtual paving thickness of backfill, tonnage of rolling machinery and rolling times.

1. After clearing the surface, the excavation and filling of subgrade shall be carried out according to the control of elevation and line position. The construction waste soil in the excavation area is better and transported to the filling area on site, and the domestic waste soil is transported out. The filling area shall ensure the replacement depth of 1.0m under the roadbed, and the key control parameters shall be implemented for filling and rolling. The 0.4m thickness of the upper part of the reserved subgrade shall be filled with purchased plain loess conforming to the standard to facilitate backfilling, rolling and leveling.

2. Selection of filling materials

According to the status of waste soil in the excavation area, domestic waste shall be transported out of the site. Construction waste and its mixed soil shall be selected and used, and attention shall be paid to the control and adjustment of water content and composition.

3. Manual cooperation at construction site

For the mixed soil of construction waste transported to the filling area, spread it out mechanically, bulldoze it with a bulldozer, and manually pick up and clean the plastic, rags, steel bars, tree roots, timber, grass, etc.

4. Special treatment for individual sections

During construction, after 1.0m of subgrade replacement excavation, when encountering complex geology such as soft soil, domestic garbage miscellaneous fill, deepen the replacement 3.0m.

5. Backfilling control parameters

The thickness of each layer of construction waste soil backfill is 250~300mm, and the 20T cam vibration and 18T smooth wheel vibration roller are used to roll for 6~8 times until there is no obvious wheel mark. Rolling and filling in layers shall be completed at an elevation of 40cm below the road base. The reserved 40cm layer shall be backfilled with plain soil in accordance with relevant specifications to ensure that the compactness reaches 0.95.

6. Test and detection

The construction process of the test section strictly implements the design requirements, accepts the supervision inspection and control, and follows the construction specifications. The work is detailed and effective, and the replacement treatment is in place. After the completion of the subgrade in the test section, the testing agency was entrusted to conduct the field deflection value test. The LS data was actually 168.29~194.13, which was significantly different from the designed 248.5 (0.01mm). The results show that the design of subgrade waste soil treatment is insufficient, and the next construction must be adjusted.

3、 Scheme after change

In combination with the conclusion data of the construction of the test section, the parties involved in the construction have discussed that the waste subgrade treatment of the road project, except for the 600m test section, will be replaced with a 2.0m plan. Among them, the 1.6m lower layer is backfilled with on-site waste soil, the control content of domestic waste is 5%, and the maximum particle size of construction waste is not more than 12cm; The upper 40cm layer is respectively from 20cm plain soil and 20cm lime soil (8%) to the road bed surface; Lay a layer of two-way plastic geogrid at -1.2m and -2.0m below the roadbed surface.

On the basis of the implementation of the subgrade waste treatment scheme, since the compactness of the construction waste soil cannot be detected, the control method of the relevant parameters for the continued implementation of the subgrade treatment and filling is formulated to ensure the construction quality of the subgrade project. Key parameters are: virtual paving thickness of backfill, tonnage of rolling machinery and rolling times.

1. After clearing the surface, the excavation and filling of subgrade shall be carried out according to the control of elevation and line position. The construction waste soil in the excavation area is better and transported to the filling area on site, and the domestic waste soil is transported out. Due to the large replacement depth and excavation volume, the green belts on both sides must be used to temporarily stack the earthwork. The excavation and filling areas shall ensure at least 2.0m replacement depth below the roadbed surface.

Considering the mutual influence between the elevation of rainwater engineering pipeline and gravel foundation and the laying elevation of the upper and lower layers of geogrid on the subgrade, after the subgrade replacement is excavated or filled to the bottom surface of -2.0m below the roadbed, the rainwater ditch shall be excavated at the bottom surface of the replacement. After the foundation gravel is laid, the lower layer of geogrid shall be laid, and then the on-site soil and gravel (pipe trench part) shall be used At the same time, fill to the elevation of the bottom of the rainwater pipe, and then fill to the height above the top of the rainwater pipe with the full section of the site soil. Then, excavate the rainwater pipe trench to the design height of the pipe bottom, treat and level the foundation gravel previously laid, and then lay the medium coarse sand cushion at the pipe bottom to complete the pipe laying and installation, inspection well construction and trench backfilling. Then lay the upper layer of geogrid on it, fill it with on-site soil and gravel (pipe trench part) at the same time until the pipe top is covered with 0.5m, and then fill it with on-site soil in full cross section to a height of -0.4m below the roadbed surface. Finally, a layer of 0.2m plain soil and a layer of 0.2m 8% lime soil shall be filled to the roadbed elevation. In case of conflict between geogrid and pipe elevation during this construction process, the laying elevation of geogrid can be adjusted within 40cm above and below, but the geogrid of the whole layer shall not be disconnected at the transverse section of subgrade.

2. Selection of filling materials

According to the status of waste soil in the excavation area, a large amount of domestic waste should be removed and transported out. Construction waste and its mixed soil should be selected for use. The content of domestic waste should be controlled within 5%. The maximum particle size of construction waste should not exceed 12cm. Attention should be paid to the control and adjustment of water content and composition.

3. Manual cooperation at construction site

For the mixed soil of construction waste transported to the filling area, spread it out mechanically, bulldoze it with a bulldozer, and manually pick up and clean the plastic, rags, steel bars, tree roots, timber, grass, etc.

4. Special treatment for individual sections

During construction, after 2.0m of subgrade replacement excavation, when encountering complex geology such as soft soil, miscellaneous fill of domestic waste and chicken house shaped domestic waste pit, deepen the replacement by 3.0-5.0m.

5. Backfilling control parameters

The thickness of each layer of construction waste soil backfill is 250~300mm, and the 20T cam vibration and 18T smooth wheel vibration roller are used to roll for 6~8 times until there is no obvious wheel mark. Rolling and filling in layers shall be completed at an elevation of 40cm below the road base. The reserved 40cm layer shall be backfilled with plain soil and 8% lime soil in accordance with relevant specifications to ensure that the compactness reaches 0.95.

6. Geogrid laying

The geogrid used for the subgrade is made of two-way plastic material. The required mesh size is 40 × 40mm, the longitudinal tensile strength is ≥ 20KN/m, and the transverse tensile strength is ≥ 30KN/m. The geogrid shall be paved in sections according to the length of each construction section, and the paving width is equal to the width of the subgrade structure. Manual laying, nylon rope binding and lapping, steel nail positioning, mechanical backfilling and embedding are adopted. During the paving process, wrinkles and unevenness shall be avoided, and vehicles shall not be driven into the area for rolling, and the surface of the lower layer shall be free from debris and sharp rock blocks. When paving soil materials, vehicles shall not turn around on the soil cushion. When the thickness of the filled soil materials is less than 30cm, heavy compaction machinery shall not be used for compaction.

7. Test and detection

The construction process strictly implements the design requirements, accepts the supervision inspection and control, and follows the construction specifications. The work is detailed and effective, the replacement treatment is in place, and the compaction and appearance effects are good. According to the field test of the subgrade deflection value conducted by the testing agency again, the actual LS data is 273.34~313.28, which meets the design requirements of 248.5 (0.01mm), and the subgrade quality is solid and reliable.

4、 Operation effect

After the overall completion of the road project, after two years of actual operation, the reliability and actual effect of the two treatment schemes are quite different. In the 600m test section with 1.0m replacement, the pavement has earthworm like cracks that are not connected horizontally, the maximum width of which is 8mm, and one crack every 12-15m in the longitudinal direction, indicating that the subgrade strength and integrity are insufficient. The normal construction section is 1500m long. Although it has been running for two years, there are numerous vehicles of different sizes passing through, but the appearance, integrity, flatness, etc. have not changed at all. No longitudinal and transverse cracks are found, which fully meets the quality standards of normal roads. All parties have evaluated it as excellent and reliable.

To sum up, how to dispose of construction waste in the demolition of urban construction and how to dispose of construction waste deeply buried in the construction of municipal road subgrade has become an important and common problem in the urbanization construction, both of which have the same character. For construction waste, the key to solve this problem is how to avoid dumping and on-site utilization, and how to formulate scientific and applicable methods. In that case, only when reasonable, reliable, simple and easy to operate methods are implemented in the construction of subgrade filling with construction waste, can the good effect of cost saving and comprehensive utilization be achieved and higher economic and social benefits be created.
