The inspection well in daily operation not only bears the dynamic load of vehicles, but also bears the pressure of external surrounding soil and underground hydrostatic pressure. Beside of complex internal environment, well chamber is corroded by waste liquid and waste gas for a long time, which affects its sealing and structure. There are many diseases in the process of use, such as man-made damage, reinforcement leakage, inner wall defect, etc., which will result in shaft wall leakage, collapse and other.

The prefabricated anti-corrosion concrete inspection well has simple structure and is easy to be installed. The built-in PVC anti-corrosion lining can improve the sealing and anti-corrosion of the inspection well, prevent sewage leakage, have good impermeability, and improve the quality and service life of the inspection well.

The prefabricated anti-corrosion concrete inspection well is made by high-frequency shaking table through vibration molding production technology with high production efficiency. The prefabricated anti-corrosion concrete inspection well is matched with various pipelines, and the construction of inspection well is simple and fast.
