Technical Field
An anti-seepage concrete pipeline is used for urban drainage and belongs to the technical field of concrete pipelines.
Background
Concrete pipe refers to a pipe made of concrete or reinforced concrete for transporting fluids such as water, oil, gas, etc. The concrete pipe can be divided into four types, namely plain concrete pipe, common reinforced concrete pipe, self-stress reinforced concrete pipe and prestressed concrete pipe.
The concrete pipeline is formed by centrifugal method, vibration method, rolling method, vacuum operation method and rolling, centrifugal and vibration combined method. Prestressed concrete pressure pipes are being developed more in china and many other countries in order to improve the service properties of concrete pipes. The pipe is provided with longitudinal and circumferential prestressed reinforcements, so that the pipe has high crack resistance and impermeability. In the 80 s, China and other countries developed self-stressed reinforced concrete pipes, which are mainly characterized by utilizing the expansion of self-stressed cement in the hardening process to generate prestress, and simplifying the manufacturing process. Compared with steel pipes, the concrete pipe can save a large amount of steel, prolongs the service life, has low factory building investment and convenient laying and installation, and is widely applied to factories, mines, oil fields, ports, urban construction and farmland hydraulic engineering.
At present, concrete pipelines are adopted as pipeline system members in drainage systems of most cities in China. However, the existing concrete pipeline as a member of a drainage system has the following technical problems:
1. the existing concrete pipeline is easy to have the phenomena of pipeline collapse or crack, water leakage and the like;
2. the maintenance difficulty is high after leakage occurs, and a large amount of manpower and material resources are required to be input;
