Convenient-to-mount efficient drainage device for bridge expansion joint and excavation method

Abstract

The invention discloses a convenient-to-mount efficient drainage device for a bridge expansion joint. The device comprises a vertical plate, wherein a water guide plate is fixedly mounted on the innerside of the vertical plate, a mounting mechanism is connected to the interior of the vertical plate, a mounting rod is arranged in the mounting mechanism, and a threaded block is mounted on the outerwall of the mounting rod in a threaded mode. According to the device, under the action of the mounting mechanism, the vertical plate is closely mounted on the inner wall of the expansion joint and isfixed through the mounting rod and the threaded block, so that the vertical plate is supported and fixed on the inner wall of the expansion joint, a cover plate is fixedly connected with the verticalplate through a first threaded rod, the cover plate reinforces a joint of the vertical plate and the expansion joint at the top, rain erosion is avoided, an L-shaped plate, a T-shaped plate and the vertical plate are firmly connected under the action of the first threaded rod and a second threaded rod, through the arrangement, the device can be rapidly and conveniently installed in the expansionjoint, the connection stability and leakproofness are ensured, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a conveniently installed high-efficiency drainage device for bridge expansion joints. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to cross mountains, poor geology, or meet other traffic needs to make traffic more convenient. For buildings, in order to prevent cracks or damage to the structure of bridge components due to climate temperature changes, a structural joint is set at an appropriate part along the construction joint direction of the building or structure. This structural joint is an expansion joint. [0003] The existing bridge expansion joints usually drain the water on the bridge directly through the expansion joints, and do not have a device for qu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem of the existing bridge expansion joints. Usually, the water on the bridge is directly discharged through the expansion joints. There is no device for quick installation of the expansion joints to facilitate efficient drainage, and there are no stones and impurities in the water. The mechanism for isolating dirt such as branches, and the mechanism for cleaning the spacers in the later stage of use will lead to a short service life of the bridge expansion joints, easy to block later, lose the drainage function, and affect the overall drainage effect of the bridge. And proposed a convenient installation of bridge expansion joints with high-efficiency drainage device and excavation method
