水泥 Treatment of cement 在拼接后漏水现象 Water leakage in pipes after splicing
We all know that cement pipes are one by one. When we install the equipment, we will splice multiple cement pipes together. If the splicing operation is not completed, the cement pipe may leak. Today, the editor of the cement pipe will tell you how to deal with the leakage of the cement pipe.
According to the standard construction, mouth cleaning, chiseling, grouting, caulking, jointing, compaction and polishing. The foundation should also be done well. Pay attention to maintenance after the interface, and later care is also critical.
Use asphalt bast to plug the seam, apply a layer of asphalt on its surface, and then wrap it with linoleum within a certain width of the seam opening, and then apply a layer of asphalt, so-called "two oils and two materials". Culverts are basically treated this way.
Depending on whether you are a mouthpiece or a flat mouth tube, to ensure that it does not leak, the same foundation must be done. You can pour the concrete cushion first and then install the tube, butt joints are flat. The socket pipe should be properly mortared at the lower mouth of the pipe to ensure that the width around the mouth is consistent. Plug seams to block the seams tightly.
The pipe is sealed with a seal at the joints of the pipe, which is a standard operation. Only when strictly according to the construction operation standards can we reduce the leakage. In order to be 100% watertight, it is necessary to choose a flexible interface, that is, a rubber strip rubber ring interface for the cement pipe. The rubber ring is acquired from the supplier when the cement pipe can be purchased.
Type of drain pipe
① Galvanized iron pipe
Galvanized iron pipe is the most widely used material. China is now gradually screening this type of pipeline.
② Copper tube
A more traditional and expensive pipeline raw material is convenient to use and construct.
③ stainless steel tube
Stainless steel pipe is a more useful pipe material. The chance of being selected in a decorative project is low.
④ Aluminum-plastic composite pipe
Aluminum-plastic composite pipe is a kind of more popular pipe on the market now.
⑤Stainless steel composite pipe
The stainless steel composite pipe and the aluminum-plastic composite pipe are similar in structure.
PVC (polyvinyl chloride) plastic pipe is a modern composition material pipe.
Second, the use of drainage pipes
Due to the strong pressure capacity of the drain pipe, the use of the drain pipe is very wide, and it can be used for the special pipes of large-scale drainage and sewage pipe networks. Today, according to the size of the drain pressure of the drain pipe, we summarize the relevant uses for you The first common sense is:
① Vertical and horizontal drainage on the back of various retaining walls and side ditches of expressways;
②Slope soil and water conservation for hillside development;
③ drainage of tunnels and underpasses;
④ underground drainage of site preparation works;
⑤ Longitudinal and lateral drainage and water permeability of expressways;
⑥ Water supply and drainage for municipal engineering, water purification plants, sewage plants, garbage dumps, etc.
1. It is necessary to check whether each department is normal before using it. Make sure that the hoses are firmly connected.
2. Strictly abide by the provisions in the primary parameters when using, and avoid overloading. Maybe continuous cracking after reaching the trip. Otherwise, when the lifting height or lifting tonnage exceeds the regulations, the top of the oil tank will cause serious oil leakage.
3. If the amount of oil in the pump body is lacking, it is necessary to first participate in the working oil (32 # hydraulic oil) in the pump before working.
4. For the electric pump, please refer to the operation manual of the electric pump.
5. The center of gravity of the heavy object should be selected properly, the point of force of the electric jack should be reasonably selected, the bottom surface should be flat, and the soft and hard conditions of the ground should be considered together, whether the tough wood should be lined, and the placement should be stable to avoid sinking or skewing the load.
6. After the electric jack lifts the heavy object in, the support should be used to support the heavy object in time to prevent the electric jack from being used as a support.
