Bridge floor body and bridge

Abstract

The invention discloses a bridge floor body and a bridge. The bridge floor body comprises bridge piers and a bridge girder vertically erected at the top ends of the bridge piers, the bridge girder isconnected in a clamped mode through supports at the top ends of the bridge piers, the bridge deck body of an arc-shaped structure design is arranged on the outer surface of the upper end of the bridgegirder, and drainage systems are arranged at the low points of the two sides of the bridge floor body. Guardrails are fixedly connected to the two sides of the outer surface of the upper end of the bridge floor body, a three-way type upper pipeline is arranged on the outer surface of the front end of the bridge main material and connected with drainage systems on the two sides of the bridge girder, and a lower pipeline is arranged in the middle of the outer surface of the front end of the pier and corresponds to the upper pipeline. An elastic stretching mechanism is arranged between the upperpipeline and the lower pipeline, and a fixing mechanism is arranged between the pier and the lower pipeline. The drainage system is matched with an internal driving mechanism to effectively crush, clean and filter impurities flowing into the drainage pipeline on the bridge floor body, and the blockage phenomenon in the drainage process of the upper pipeline and the lower pipeline is reduced.

Description

technical field [0001] The invention relates to the technical field of transportation highways, in particular to a bridge surface body and a bridge. Background technique [0002] As the hub of highway engineering, bridge engineering brings convenience to people's travel and occupies an important position in the national economy. Most of the bridges currently erected are prefabricated bridges, such as prefabricated small box girders and T-beams. The prefabricated bridge is a kind of bridge in which the main girder is prefabricated in the factory, and then the vertical and horizontal connection and bridge deck concrete leveling construction are carried out on site after the main girder is erected. The structure of the prefabricated bridge mainly includes the prefabricated main girder, the vertical and horizontal wet joints and the leveling layer of the concrete bridge deck.

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors have found that at least the following problems in the prior art have not been solved: 1. Especially for municipal and highway bridges, in order to ensure safe and unobstructed driving, prevent the bridge deck structure from being eroded by precipitation and affect the bridge. Durability, in accordance with the requirements of relevant national regulations, a complete bridge deck drainage system should be installed. The design of the bridge deck drainage system is mainly to set up vertical and horizontal slope drainage on the bridge. The drainage pipes in the body and piers are introduced into the ground drainage system

In the past, due to the limited construction quality and maintenance management level, bridge drainage pipes generally adopt the method of laying exposed pipes, that is, the way of hanging drainage pipes outside the bridge girder and pier columns, and connecting to the road drainage pipe network at the bottom of the pier; A small number of bridges use drainage pipes inside the structure of the main beam and pier columns, but many of them have broken the drainage pipes at the junction of the beam body and pier columns due to the temperature expansion and deformation of the bridge. In addition, due to various reasons After the drainage pipe is clogged, it cannot be cleared and the built-in pipe is scrapped, and part of the structural body needs to be removed to re-lay the exposed pipe; 2. With the improvement of bridge technology and materials, the existing bridge drainage system is relatively complete, but especially for It is used in areas with large green areas. In autumn, dead leaves are easy to enter the drainage pipes and cause blockage of the pipes, making it impossible to effectively carry out drainage operations inside the pipes. The utilization rate of the drainage system is low, and the water volume on the bridge deck is large, which will not only increase erosion The probability of the bridge deck body will reduce its service life, and the dead leaves will block and rot, causing the generation of sludge pollutants inside the pipeline, which will be difficult to clean up manually
