Copper waterstop (also called copper waterstop, red copper waterstop, copper waterstop) http://www.023xyys.com : used for setting in hydraulic structures Construction joint The requirements for water stop materials of different projects are different, so there are different specifications of water stop copper sheets.
Chongqing Xiangyin water stop copper sheet can be formed and processed on the basis of red copper water stop according to the requirements of the customer's drawings. It can form various shapes such as W, F, D, T, Z, etc. The length of forming and processing in the factory can be unlimited, which can reduce the welding process in the project construction, reduce the cost for customers, and ensure the project quality at the same time.
Copper waterstop shall be executed in accordance with the standard GB/T2059-2008 in DLT5115-2008 Technical Specification for Joint Waterstop of Concrete Face Rockfill Dams. It shall be made of T2 or T3, with copper content ≥ 99.80%, tensile strength ≥ 205MPa, elongation ≥ 30% and strong corrosion resistance. It is widely used for foundation water stop, dam body water stop, dam crest water stop, gallery water stop of all kinds of high hydraulic buildings, as well as water stop of holes in the dam body, plant water stop, and horizontal joint water stop under the overflow surface. Copper waterstop is an ideal product to prevent leakage. We can also make copper waterstops of different shapes according to customers' requirements.
The main characteristics of copper waterstop are: strong corrosion resistance; High strength, able to withstand large deformation; The appearance outline is clear, without cracks, folds and pits.
The water stop copper sheet is made of red copper, with strong corrosion resistance, good flexibility and weldability, easy to form, no cracking, and good waterproof and leak proof performance. Copperplate The waterstop has strong corrosion resistance, high tensile strength, good toughness, can withstand large deformation, clear appearance, no cracks, folds, and pits. It is executed in accordance with the GB/T2059-2008 standard in DLT5115-2008 Technical Specification for Joint Waterstop of Concrete Face Rockfill Dams. It is made of T2 or T3, with copper content of 99.80% or more, tensile strength of ≥ 205MPa, elongation of ≥ 30%, and strong corrosion resistance. The red copper waterstop produced and processed by relevant national departments door Test and issue corresponding certificates of conformity.
Because copper has excellent workability and good scalability floor It is not easy to break when uneven settlement occurs, so as to improve the seismic capacity and impact resistance of hydraulic structures, and play the role of anti subsidence. At the same time, due to the strong corrosion resistance of red copper, it can protect water conservancy projects to achieve the effect of impermeability and water stop.
It is mainly used between floors and between floors and piers in water conservancy projects expansion joint To prevent groundwater leakage, it is applicable to the foundation water stop, dam body water stop, dam crest water stop, gallery water stop of all kinds of advanced hydraulic buildings, as well as the water stop of holes in the dam body, plant water stop, and horizontal joint water stop under the overflow surface. It is an ideal product to prevent leakage.
Our company provides T2M copper waterstop strip, T2Y2 copper waterstop strip, T3M copper waterstop strip and T3Y2 copper waterstop strip, which can be molded into W, F, D and T types based on the requirements of customer drawings, Various shapes, such as Z type, can be infinitely long, which can reduce the welding process in project construction to a certain extent, reduce costs for customers, ensure project quality, and meet customers' different requirements for copper waterstop specifications. It is produced in strict accordance with national quality standards, with stable performance, safe and reliable quality, and is a manufacturer of high-quality water stop copper sheets.
Which is better, copper waterstop or stainless steel waterstop? http://www.023xyys.com
In addition to copper waterstop and stainless steel waterstop, rubber waterstop and PVC waterstop are also available in the market. As we know, rubber waterstop and PVC waterstop are prone to aging and embrittlement. Compared with the stainless steel waterstop, the waterstop copper strip is expensive, easy to be damaged in construction, and the on-site joint welding process is complex. However, due to its high strength, strong resistance to water pressure, surrounding seepage, and corrosion resistance, it is still preferred to use copper waterstops in high dams.
Although the elongation of stainless steel waterstop is equivalent to that of copper waterstop, it is generally used in waterstop parts that need to be connected with embedded steel members because of its larger rigidity and larger stress in concrete when displacement occurs, and the welding process of stainless steel waterstop is relatively complex.
The performance of various waterstop materials varies greatly, and each has its advantages and disadvantages. EPDM has good aging resistance, but low strength; Natural rubber has high strength, but its slow aging property is poor in preventing direct sunlight. Copper waterstop and stainless steel waterstop have high strength, but their elongation is quite different from that of rubber and plastic. Therefore, when the waterstop with different materials is used to construct multiple waterstops, the reliability of the waterstop structure is high.
Construction of plastic filler for water stop copper sheet
During the construction of plastic filler for water stop copper sheet, attention shall be paid to that V-shaped groove embedded with plastic filler shall be reserved at the top of the joint according to the shape and size required by the design. Plastic filler construction shall be carried out after the concrete strength of corresponding parts reaches 70% of the design strength. The embedding construction should be carried out in the daytime when the daily average temperature is higher than 5 ℃ and there is no rain, otherwise special measures should be taken. When the plastic filler is constructed by stages, the end of the joint shall be sealed.
Before the plastic filler is embedded, the concrete surface in contact with the filler shall be cleaned without loose concrete blocks; If corrugated rubber waterstop is set in V-groove, the bolts of corrugated waterstop shall be tightened again when plastic filler is embedded. After the contact surface is dried, the adhesive shall be applied. If it cannot be dried, the wet surface adhesive shall be used.
When PVC or rubber bar is set at the seam, the PVC or rubber bar shall be embedded into the lower mouth of the joint V-groove before the plastic filler is embedded, and the bar wall and the joint wall shall be embedded tightly. PVC or rubber bar joints should be welded and fixed. When plastic filler is embedded, it shall be constructed according to the process requirements of the manufacturer. The shape after embedding shall meet the design requirements, and the external surface shall be free of cracks and ups and downs. After passing the inspection with the mold, install the anti-seepage protection cover in sections.
