3、 Application of reinforced concrete cement pipeline in urbanization construction
With the acceleration of China's urbanization process and the implementation of the village to village project, cement and related cement products, such as cement pipelines, are increasingly used in China, and the demand is also increasing, because while carrying out urbanization construction, it is necessary to take into account the construction of pipeline sewage, residential water pipelines, etc, All aspects of construction need cement pipes. What are the installation and construction steps of cement pipes?
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.
More rigorous and standardized measures and construction steps are also proposed for the cement pipeline according to the requirements: first, the surveying and setting out work should be in the charge of a full-time surveyor, and the construction of surveying and setting out records and check filing system should be strictly implemented, using calibrated instruments. According to the design drawings and pile handover records, check the bench marks, establish temporary bench marks, do a good job of protection, and conduct closed resurvey to control the elevation. Secondly, after the trench is excavated in sections, the elevation and elevation shall be reviewed in time to control the elevation of excavation, cushion and foundation surface. Squeeze and compact the stones, remove the soil, lay the reinforcement, erect the plank, and then pour the ground. 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.
