Municipal drain pipe connecting structure

Abstract

The invention discloses a municipal drain pipe connecting structure. The municipal drain pipe connecting structure comprises a connecting piece and drain pipes, wherein the left end of the connectingpiece is connected with the right end of one drain pipe, the right end of the connecting piece is connected with the left end of the other drain pipe, and annular insertion grooves into which the drain pipes are inserted are respectively formed in the left and right ends of the connecting piece; sealing structures are respectively arranged on both ends of the connecting piece, the sealing structures comprise pressing pieces, annular push pieces, sealing rings I, pressing blocks and tightening covers, a plurality of pressing pieces are respectively arranged on the side walls of both ends of thedrain pipes, the pressing pieces comprise bending parts, pressing parts and push blocks, the bending parts are in an arc shape and are respectively arranged towards the middle of the drain pipes, andone end of the bending parts is connected with the drain pipes; and a plurality of reinforced structures are respectively arranged on the outer walls of the left and right ends of the drain pipes, and the reinforced structures are circumferentially arranged along the drain pipes. The invention aims to provide the municipal drain pipe connecting structure, and the municipal drain pipe connecting structure has the advantages of good leakproof effect, the stable structure and convenience in installation.

Description

technical field [0001] The invention relates to the technical field of connection structures, in particular to the connection structure of municipal drainage pipes. Background technique [0002] Municipal water supply and drainage pipes refer to the rainwater and sewage pipes under the municipal roads, which are usually called municipal drainage pipes in engineering. With the development of society and the vigorous development of drainage projects, the application of municipal water supply and drainage pipes has become more and more. All municipal water supply and drainage pipes require connectors to connect and install the water supply and drainage pipes at both ends. However, there may be gaps in the existing municipal water supply and drainage pipes when they are connected and installed, or they will be subject to impact, vibration, and wear under long-term use. This will cause loosening and water leakage at the joints of the pipelines, and increase the later maintenance ...
