Plugging device for drainage pipeline opening in inspection well and construction method of plugging device
The invention provides a plugging device for a drainage pipeline opening in an inspection well and a construction method of the plugging device. The plugging device comprises a semi-conical hollow precast block base, a cylindrical hollow precast block, a reserved water stop strip clamping groove and a water swelling water stop strip. The semi-conical hollow precast block base and the cylindrical hollow precast block are poured at the same time, are of an integral hollow concrete structure, can be prefabricated according to the diameter of a pipeline needing to be plugged, and are suitable for drainage pipelines of different materials and pipe diameters. The reserved water stop strip clamping groove is reserved when the precast block is poured and used for installing the water-swelling water stop strip, and the plugging function is effectively achieved. The drainage pipeline opening plugging construction in the inspection well is convenient, operation is easy, universality is high, cost is reduced, efficiency is improved, and the method is worthy of popularization.
本发明提供了一种检查井内排水管道口的封堵装置及其施工方法，其中装置包括半圆锥型中空预制块底座、圆柱型中空预制块、预留止水条卡槽、遇水膨胀止水条四部分构成。半圆锥型中空预制块底座与圆柱型中空预制块同时进行浇筑，为整体式中空混凝土结构，可根据需要封堵的管道直径进行预制，适用不同材质、管径的排水管道。预留止水条卡槽，预制块浇筑时进行预留，用于安装遇水膨胀止水条，有效实现封堵功能。本发明方便进行检查井内排水管道口封堵施工，操作简单，通用性强，降本增效，值得推广。
