Concrete inspection well with PVC (polyvinyl chloride) lining

PENG YUGEN

The invention relates to the related technical field of concrete pipes, discloses a concrete inspection well with a PVC (polyvinyl chloride) lining, and aims to solve the problem that a plate and concrete are not easy to assemble and connect, a lock tongue at the end part of one lining plate is inserted into a lock groove part at the end part of the other lining plate, so that the two lining plates are connected and fixed, and the service life of the two lining plates is prolonged. According to the inner diameter of the needed inspection well body, the inner lining plate which can be just placed on the inner side of the inspection well body is assembled, thermal expansion and cold contraction can be prevented through the assembled inner lining plate, assembling is easy, corrosion prevention and leakage prevention are achieved, and the effect of convenient assembling and fixing is achieved.

本申请涉及混凝土管相关技术领域，公开了一种PVC内衬的混凝土检查井，为了解决板材和混凝土不易组装连接的问题，通过内衬板端部的锁舌插入至另一个内衬板端部的锁槽部中，从而实现两个内衬板之间连接固定，依据所需的检查井体的内径大小，从而组装一个能够正好放置在检查井体内侧的内衬板，通过装配式组装的内衬板，不仅能够防止热胀冷缩，还易于组装并做到防腐和防渗漏，实现了便于组装固定的效果。
