With the improvement of people's requirements for living environment, various construction measures have also raised the requirements accordingly. In the construction of drainage and sewage pipelines for urban construction, the requirements for the installation of cement pipelines have also been raised accordingly. This not only makes strict requirements on the quality and material of cement pipes, but also regulates the construction. Corresponding construction management specifications have also been formulated for the installation of cement pipelines. First of all, during installation, it is necessary to measure and set out first, and then dig trenches and earth according to the specifications of cement pipes. When laying the pipeline, the pipeline foundation construction shall be carried out first, and then the cement pipeline shall be cleaned inside the pipe, and then the concrete pouring inspection well and the anchor pouring shall be carried out. After these works are completed, the trench shall be backfilled as required.

The shape of square pile is easier to develop a non welded quick connector, which can truly achieve all-weather construction, and construction is faster, which can avoid cracking of welded pile head in high groundwater level. 1) Positioning, centering and leveling of the pile driver. After the mixing pile position is placed, move the mixing pile driver to the designated pile position, centering and leveling (leveling with a level). 2) Adjust the verticality of the guide frame, and use a theodolite or plumb bob to control the verticality of the guide frame in both directions. According to the design and specification requirements, the verticality is less than 1.0% of the pile length. 3) The slurry is premixed in advance. While the deep mixer is premixing and sinking, the cement slurry is mixed in the background and put into the aggregate hopper before grouting. The cement grade 425 # ordinary silicate cement is used to mix the slurry, the water cement ratio is controlled in the range of 0.45~0.50, and the cement consumption per meter of deep mixing pile is not less than 50Kg according to the design requirements.

Temperature: for the solidified mortar layer or concrete component, if the cement pipe factory is often in high temperature and extreme heat conditions, there will be strength loss. This is because the calcium hydroxide in the cement stone will be separated under high temperature conditions. In addition, some aggregates will separate or expand in volume under high temperature conditions. Cement raw materials: when selecting cement, cement varieties with high strength, good durability, appropriate price and reliable quality should be selected. The cement varieties with special properties shall be selected according to the service conditions of cement pipes; It is an important condition to ensure the durability of cement pipes to select better sand and stone aggregates, and sand and stone aggregates with good quality and qualified technical conditions.

Before the cement pipe is laid down, the elevation of the pipe top shall be controlled with a level gauge. The pipes shall be arranged from low to high. The pipes shall be placed in place and then corrected manually with excavator. The socket and spigot shall face the upstream direction, and the inner wall of the socket and spigot shall be coated with washing water, so that the rubber ring can slide in smoothly when inserting pipes and facilitate installation. In addition, the cement pipes passing the installation inspection shall be backfilled immediately, and the pipes with larger specifications shall be backfilled to at least one time the pipe diameter above the pipe top to ensure that the cement pipes can avoid directly loading the ground pressure. After backfilling, the ground shall be cleaned. In this way, the laying of a cement pipeline can be completed, and a complete underground pipeline system can be officially put into use, making its due contribution to the environmental protection construction of the city.
