Assembly type pier drainage pipe

Abstract

The invention discloses an assembly type pier drainage pipe which comprises a main drainage pipe, branch pipes, connecting ends, a mounting mechanism, a filtering mechanism, a mounting frame, a filterscreen, a sealing mechanism, a floating ball, a connecting rod, a spring and an inner groove. The pipe has the beneficial effects that at ordinary times, some dust impurities can be shielded by the floating ball, so that a large number of dust impurities are prevented from entering the branch pipes and then entering the main drainage pipe to block the main drainage pipe, the smoothness of the main drainage pipe is guaranteed, and accumulated water at the top of a bridge pier firstly enters two branch pipes in rainy days; when the buoyancy borne by the floating ball is increased to a certain degree, the floating ball can gradually float, an opening is formed between the floating ball and the branch pipe, accumulated water can smoothly enter the opening, after entering the branch pipes, theaccumulated water can be filtered by the filter screen, large-particle impurities are further prevented from entering the main drainage pipe, blockage is avoided, and the service life of the main drainage pipe is prolonged; and finally, the interior of the main drainage pipe is further prevented from being blocked by sundries, and smooth drainage is guaranteed.

Description

technical field [0001] The invention relates to a drainage pipe, in particular to an assembled pier drainage pipe, which belongs to the technical field of pier drainage pipes. Background technique [0002] The bridge pier is a substructure that supports the bridge span structure and transmits the dead load and vehicle live load to the foundation, and the bridge abutment is located on the two lakes of the bridge. The piers are between the two abutments. The function of the bridge pier is to support the bridge span structure: the surface abutment support not only plays the role of supporting the bridge span structure, but also connects with the embankment and prevents the embankment from slipping. In order to protect the analysis platform and embankment filling, some protection and diversion projects are often done on both sides of the analysis platform. Among them, the pier drainage pipe is mainly responsible for the drainage of rainwater and sewage, which is very important...
