Description

Technical Field

[0001] The utility model relates to the technical field of plastic inspection wells, and more specifically, to a leak-proof plastic inspection well. Background Art

[0002] Plastic inspection wells, commonly known as plastic "manholes", are drainage auxiliary structures set at the intersections, turning points, pipe diameter or slope change points, drop water points of plastic drainage pipes, or at certain intervals on straight pipe sections, which are convenient for regular inspection, cleaning, and dredging of pipes. Most of the well seat parts of plastic inspection wells are formed by one-time injection molding, and fittings such as reducing joints, angle-changing joints, and rubber gaskets are used to achieve connections for changing pipe diameters and angles. Plastic inspection wells are developed with matching manhole covers, well shafts, and related fittings. The road surface load acts on the surrounding area of the inspection well through the manhole cover and well seat, avoiding damage to the inspection well caused by the road surface load. The well seat has the function of floating up and down, which can actively adapt to the height changes of the road surface. At the same time, the special well shaft can be cut to the corresponding length according to the on-site burial depth, which is flexible and convenient. The connection between the well shaft, the inlet (outlet) water pipe and the well seat adopts a flexible socket connection with a rubber gasket or a heat shrinkable sleeve connection, which can adapt to angle changes within a small range, is convenient and fast in construction, has good sealing performance and anti-leakage, and effectively prevents secondary pollution of groundwater. It is an environmentally friendly and energy-saving building material.
