An anti-leakage structure for municipal pipelines

Abstract

The application relates to an anti-leakage structure for municipal pipelines, which includes a pipe main body, a socket part and a socket part are respectively arranged at both ends of the pipe main body, an rubber ring is sleeved on the socket part, and The gap between them is filled with caulking material, and a stepped hole through the side wall of the socket is opened on the outer wall of the socket, and a mounting plate suitable for the stepped hole is detachably installed at the stepped hole. There are multiple countersunk grooves, the extension direction of the center line of the multiple countersunk grooves is perpendicular to the axial direction of the socket part, and there is a relief hole through the mounting plate at the center of the countersunk groove, the cross section of the relief hole It is polygonal, and there is a limit post that is adapted to the give way hole in sliding connection, and a slot for the limit post to be embedded is provided on the peripheral surface of the socket, and the limit post is far away from the slot. A screw rod is fixed vertically on the end face, and a nut screwed with the screw rod is connected in rotation in the limiting groove. The present application has the effect of improving the sealing performance of pipeline joints.

Description

technical field [0001] The application relates to the field of municipal engineering, in particular to a municipal pipeline anti-seepage structure. Background technique [0002] Municipal engineering refers to municipal infrastructure construction projects. In my country, municipal infrastructure refers to various projects that are set up within the planning and construction scope of urban areas and towns (townships) and provide residents with paid or free announcement products and services based on government responsibilities and obligations. Buildings, structures, equipment, etc. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering. [0003] An important underground project of municipal engineering is the construction of pipe networks, such as rainwater pipes, sewage pipes, water supply pipes, reclaimed water pipes, power pipes, communication pipes, etc. Among them, the water supply pipeline is generally ...
