Improved soil engineering supervision Instruction
Construction process requirements 5.2.1 Before the acceptance of the filling of the lower bearing layer, the geometric dimensions of the base should be checked, and the compaction standard should be checked (the detection and acceptance of the relevant processes should be carried out). The base that does not meet the standard should be treated to make it meet the acceptance standard. 5.2.2 Survey and setting out shall introduce temporary benchmarks near the construction site, report to the supervisor for approval, and strictly control the elevation; The amount of filler shall be controlled by the square grid on the subgrade. The longitudinal pile spacing of the square grid shall not be greater than 10m. The square grid piles shall be set on both sides of the subgrade and at the center of the subgrade in the transverse direction. Indicator piles shall be set outside the edges of road shoulders on both sides, and the dumping density of dump trucks shall be controlled with lime points in the grid to control the paving thickness of each layer. 5.2.3 Stabilized soil mixing equipment shall be used for mixing improved soil mixture in the mixing plant, and soil crushing equipment shall be equipped to remove soil lumps. Calibrate the measuring equipment, adjust the discharge amount per unit time at the discharge outlet, so that all kinds of materials entering the mixing equipment meet the requirements of mixing ratio; In addition, special attention shall be paid to whether the discharge volume per unit time at the discharge outlet is basically the same as that during calibration, and whether there are abnormal conditions such as blockage of the discharge outlet during formal mixing. When mixing the improved soil mixture in the mixing equipment, it is required to mix evenly, and the mixture shall not contain more than 10mm of soil blocks and undigested lime particles; The composition and moisture content of the mixture (the relationship between the moisture content during mixing and the optimal moisture content during rolling shall be adjusted according to the weather conditions) shall meet the specified requirements. Before formally mixing the improved soil mixture, the plant mixing equipment must be commissioned, and the plant mixing process parameters must be further reasonably adjusted and determined through various construction parameters summarized from the trial mixing and trial paving of the test section 5.2.5 Paving Calculate the paving area of each truck of mixture according to the loose paving thickness, and determine the stacking density. At the filling site, according to the quantity and paving thickness of each vehicle of earthwork, use lime points to control the dumping density of dump trucks, and at the same time, bury piles and hang lines to mark the loose paving thickness; After paving the mixture, first use a grader for initial leveling and shaping, and then use a roller to quickly roll it for 1-2 times. The pits shall be leveled. The mixture shall be initially leveled and then finely leveled. Special personnel shall be assigned to timely remove the segregation mixture and add new mixture. The compaction thickness of layered filling shall be carried out according to the compaction equipment and the method determined by the test section, and generally should be controlled within 20~28cm...... ⑶ Before filling the improved soil, indoor test shall be carried out according to the ratio provided by the design to determine the construction mix ratio. The mix proportion of improved soil shall ensure that the unconfined compressive strength and compaction quality of the mixture can meet the design requirements. The type and technical conditions of admixture outside the improved soil shall meet the design requirements. The mixture shall not contain more than 10mm soil blocks, undigested lime particles and plain soil layers. The improved soil shall have uniform color and luster, and be free of ash strips and lumps. The allowable deviation of modifier dosage is - 0.5%~+1.0% of the test mix proportion. ⑷ The shrinkage cracks of the improved soil will cause damage to the drainage surface, which is easy to cause water intrusion into the subgrade. Strictly control the compaction moisture content, ensure the compaction degree, and pay attention to curing to control the shrinkage cracks of the improved soil itself. The optimal water content control scheme is to spray water evenly into the improved soil when mixing with the plant mixing equipment when the natural water content of the soil is close to the optimal water content; If the difference between the natural water content of the soil and the optimal water content is large, it is considered to irrigate and stew the soil in blocks in the borrow area
