1. The principle of overflow well discharge method: the sewage is mainly discharged into the municipal sewage pipe through the overflow well, and the pump is used as a supplement to remove the accumulated water in the overflow well and the upstream sewage pipe. The flow should be confirmed by discharging all accumulated water within 30min. In order to reduce the operation cost, the sewage pump can be started before the peak water consumption every day to drain the accumulated water in the overflow well and the upstream pipeline. This can not only prevent sewage from staying in the pipeline for a long time and forming siltation, but also make the ponding pipe section often washed, which is conducive to pipeline ventilation and the removal of harmful gases in the pipeline.

7) The grout is repeatedly stirred and lifted. After sinking to the design depth, the grout is repeatedly stirred and lifted until it reaches the ground. 8) The pile driver is moved. After the construction of one pile, move the pile driver to the next pile position, and repeat the above steps for the construction of the next pile. Jiaxing cement pipeline, also known as cement pressure pipe and reinforced concrete pipe, can be used as sewer pipe in urban construction, sewage drainage, flood control and drainage, as well as water supply pipes and farm motor wells used in some special factories and mines. Generally, it is divided into: plain end reinforced concrete cement pipe, flexible rebated reinforced concrete cement pipe, socket reinforced concrete cement pipe, F-shaped steel socket cement pipe, plain end ring joint cement pipe, rebated cement pipe, etc.

2. Establish temporary bench marks: temporary bench marks are often required for pipeline works, which should be set at a stable place that is not easy to be collided, and the spacing should not be more than 30 meters. The closure error of temporary benchmark shall meet the specified standards. 3. Trench excavation is mainly carried out by excavator, supplemented by manual bottom cleaning. Rainwater bucket connecting pipes and branch pipes are manually excavated. During excavation, pay attention to the change of soil quality, and support and enclosure the sections with signs of collapse. 4. Excavate by excavator until the elevation of the trench bottom is about 10cm. Do not excavate the reserved trench bottom soil, and then remove it manually to trim the trench bottom. Manually clean the tank, carefully check the soil at the bottom of the tank for disturbance, and if there is any disturbance, special treatment shall be carried out.

The newly developed hollow square pile has completely overcome this disadvantage by combining centrifugal and prestressed technology with internal hollow. In the market, prestressed concrete pipe piles are used more frequently in industrial and civil buildings. They overcome the shortcomings of the previous pile types and have their own characteristics, but the disadvantages are also obvious: the appearance is smooth and round, especially when used as friction piles, the friction force with soil is small, and many projects have to use pipe piles with large outer diameter or simply use solid square piles, Increased project cost; The bending resistance of thin-walled pipe piles is poor, especially the shear resistance and tensile resistance of the pile body, which has buried hidden dangers in the foundation of the building

Maintenance means no steam curing tank. After the cement pipe is made on the cement pipe making machine, it is not necessary to open the grinding tool. Put the cement pipe mold and cement pipe outdoors for regular maintenance. Generally, after the cement pipe is made, it takes one day to carry out outdoor maintenance. The grinding tool can be opened the next day. After the mold is made, it also needs to carry out 4-6 days of regular maintenance, and full-time personnel should spray water on the cement pipe three times a day, The time of sprinkling is usually once in the morning, once in the afternoon and once at noon. The purpose of sprinkling is to maintain the environmental humidity of the cement pipe so that the concrete can gradually coagulate itself. The frequency of sprinkling can also be increased and reduced according to the environmental humidity of seasonal changes in weather conditions. But of course, there are more cement pipe molds required for maintenance.
