Novel drainage pipe flexible connection device at bridge expansion joint

Abstract

The invention relates to the technical field of bridge drainage, in particular to a novel drainage pipe flexible connection device at a bridge expansion joint. Comprising a connector, a first reference rod, a second reference rod, a supporting piece and a corrugated pipe. The number of the connectors is two, and the two connectors are used for being communicated with two sections of pipe bodies of the drainage pipe respectively. And the corrugated pipe is connected between the two connectors so as to communicate the two connectors. An inner cavity is formed in one end of the first reference rod, and one end of the second reference rod is slidably matched with the inner cavity. The first reference rod is in spherical hinge connection with one connector, and the second reference rod is in spherical hinge connection with the other connector. The supporting piece is attached to the inner side of the corrugated pipe. The first reference rod and the second reference rod are both fixedly connected with positioning pieces, the multiple positioning pieces are evenly distributed in the circumferential direction of the first reference rod and the circumferential direction of the second reference rod at intervals, and each positioning piece is fixedly connected with one supporting piece. The probability of structural collapse of the flexible connection part can be reduced, and the probability of loosening, water leakage and other problems of the flexible connection part can be reduced.

Description

technical field [0001] The invention relates to the technical field of bridge drainage, in particular to a novel flexible connection device for drainage pipes at expansion joints of bridges. Background technique [0002] The reliability of the traditional soft connection structure used for the drainage pipe at the bridge expansion joint is low, and the soft connection part is prone to collapse after a long time of use, which directly affects the drainage capacity of the drainage system. On the other hand, the traditional soft connection structure has limited adaptability to the change of the connection direction. When the use time is long, or the deformation / displacement amount is large, the connection parts of the traditional soft connection structure have problems such as loosening and water leakage. risk. These defects are not conducive to the normal operation of the drainage system. [0003] In view of this, this application is hereby made. SUMMARY OF THE INVENTION ...

Problems solved by technology

[0002] The reliability of the traditional soft connection structure used for drainage pipes at bridge expansion joints is low. After a long time of use, the soft connection part is prone to collapse, which directly affects the drainage capacity of the drainage system

On the other hand, the traditional soft connection structure has limited adaptability to changes in the connection direction. When it is used for a long time, or the deformation / displacement is large, the connection parts of the traditional soft connection structure may loosen and leak. risk

These defects are not conducive to the normal work of the drainage system
