Municipal bridge hidden drainage system

Abstract

The invention relates to a hidden drainage system of a municipal bridge. The system comprises a plurality of drainage channels formed in the two sides of a box girder and used for collecting rainwater, box girder hoses arranged on the box girder and hermetically connected with the water outlets of the drainage channels, bridge pier hoses arranged on a bridge pier and hermetically connected with amunicipal drainage facility, galvanized steel pipes arranged between the box girder hoses and the bridge pier hoses and connected with the box girder hoses and the bridge pier hoses in a sealed mode,and pipeline sealed connection devices arranged at the two ends of the box girder hoses and the two ends of the bridge pier hoses and playing a role in sealed connection. The sealed connection devicecomprises end blocks tightly and fixedly connected to the two ends of the box girder hoses and the pier hoses, a sealing head rotationally connected with the end blocks, sealing joints installed at both ends of galvanized steel pipes and at the outlets of the drainage channels and at the inlet of municipal drainage facilities and with the outer wall in threaded connection with the inner wall of the sealing head, and a rubber gasket arranged in the sealing head and tightly abutted against the end surface of the sealing joint. The system has the following effects that two ends of the box girderhose and two ends of the pier hose are not easy to separate and rainwater is prevented from directly leaking.

Description

technical field [0001] The invention relates to the technical field of bridge drainage, in particular to a concealed drainage system for municipal bridges. Background technique [0002] If there is serious water accumulation on the bridge, it will affect the structural strength of the bridge itself. For this reason, it is necessary to ensure that the bridge is equipped with a drainage system to ensure that the bridge will not generate water in the event of rain. Combined with the drainage pipes to discharge the bridge surface water to the municipal drainage facilities for treatment, but the drainage pipes of the traditional bridge drainage system are exposed, which will easily cause the drainage pipes to be corroded and damaged, and the service life will be reduced, and it will also affect the appearance of the city. Therefore, the existing hidden bridge drainage system is designed to meet the above requirements. [0003] There is an existing hidden bridge deck drainage sys...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the galvanized steel pipe placed in the box girder and the galvanized steel pipe placed in the pier and the rubber hose are connected by plugging and socketing, which is unstable and easy to make The rubber hose is separated from the galvanized steel pipe, so that the rainwater collected by the galvanized steel pipe placed in the box girder cannot flow into the ground rainwater well
