Bridge protection device for municipal engineering

Abstract

The invention discloses a bridge protection device for municipal engineering and particularly relates to the field of bridge protection. The bridge protection device comprises a protection plate; andthe protection plate is of a door-frame-shaped structure, a connecting mechanism is arranged on the inner side of the protection plate, and an anti-deformation mechanism is arranged on the front faceof the protection plate. By arranging an inner anti-collision mechanism, an outer anti-collision mechanism and the anti-deformation mechanism, collision force from the outside is consumed and weakenedtime and time again, thus damage of the external collision force to a pier is reduced, and the positive effect on the service life of the pier is achieved; and during buffering, a steel wire net richin elasticity achieves a first-stage buffering effect, holes of the steel wire net are in a honeycomb shape, the flexibility of the steel wire net can be improved, meanwhile through matching of reinforcing ribs and a buffering spring, the second-stage buffering effect on the collision force is achieved, thus the influence of the external collision force on the pier can be weakened well, and the anti-deformation mechanism is used for strengthening the rigidity of the protection plate to prevent the protection device from deforming.

Description

technical field [0001] The invention relates to the technical field of bridge protection, more specifically, the invention relates to a bridge protection device for municipal engineering. Background technique [0002] In my country, municipal infrastructure refers to various buildings, structures, equipment, etc. that are set up within the planning and construction of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The various supporting public infrastructure constructions belong to the category of municipal engineering, such as common urban roads, bridges, subways, underground pipelines, tunnels, rivers, rail transit, sewage treatment, garbage disposal and other projects, and other projects closely related to life Various pipelines: rainwater, sewage, water supply, reclaimed water, electricity (outside the red line), telecommunications, heat, gas, etc., as well as the ...

AI Technical Summary

Problems solved by technology

A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structure refers to the bridge head plate, conical slope protection, revetment, diversion engineering, etc., and the bridge piers are divided into solid piers, column piers, and bent piers, etc., according to the plane The shape can be divided into rectangular piers, pointed piers, round piers, etc. The materials for building bridge piers can be wood, stone, concrete, reinforced concrete, steel, etc. In traffic accidents, the accident rate of vehicles colliding with bridge piers is not rare, so , how to solve the problem of vehicles colliding with bridge piers has become one of the urgent problems to be solved at present. Due to the huge energy of the collision, the existing bridge piers have caused great damage to vehicles and people, thus threatening people's lives.

[0003] During the protection process of the current bridge protection device, due to the large collision force with the vehicle, the protection device is easily deformed, so that the protection effect cannot achieve the expected effect. At the same time, the operation steps are relatively cumbersome when installing the protection device. , the protective device cannot be installed quickly, which will cause troubles to the protective work of the bridge, which is not conducive to practical use
