Description

Technical Field

[0001] The utility model relates to the technical field of plastic inspection wells, in particular to a plastic inspection well. Background Art

[0002] Plastic inspection wells, commonly known as plastic "manholes", are drainage ancillary structures set at the intersection of plastic drainage pipes, bends, places where pipe diameters or slopes change, places where water falls, or at certain intervals on straight pipe sections, to facilitate regular inspection, cleaning, and dredging of pipes. The well seat of the plastic inspection well is mostly made of one-time injection molding, and accessories such as reducers, angle joints, and rubber seals are used to achieve connections that change pipe diameters and angles. The plastic inspection well is equipped with manhole covers, shafts, and related accessories. The road load acts on the inspection well through the manhole cover and the well seat, avoiding damage to the inspection well by the road 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 well shaft adopts a special well shaft, which can be cut according to the on-site burial depth. It is flexible and convenient. The connection between the shaft, the inlet (outlet) water pipe and the well seat adopts a rubber sealing ring flexible socket connection or a heat shrink sleeve connection, which can adapt to angle changes within a small range, is convenient and quick to construct, has good sealing performance, and is leak-proof, effectively preventing secondary pollution of groundwater. It is an environmentally friendly and energy-saving building material.
