Assembled type pier outer wall cleaning device

Abstract

The invention relates to an assembled type pier outer wall cleaning device, and belongs to the technical field of cleaning devices. The device comprises an annular guide rail arranged on the outer side of the circumference of a pier, a cleaning machine which is connected with the annular guide rail through a rail and a stabling and supporting structure used for fixing and supporting the annular guide rail in the middle of the pier, wherein the cleaning machine can rotate around the pier along the annular guide rail, the stabling and supporting structure comprises a supporting ring, a supporting rod, an air bag and an inflation device connected with the air bag, the supporting ring is arranged on the outer side of the circumference of the pier and is fixedly connected with the annular guiderail through a support, the supporting ring and the annular guide rail are horizontally arranged, and the diameter of the annular guide rail is larger than that of the supporting ring. The device canbe used for cleaning the outer wall of the assembled pier, so that the residual of corrosive substances is reduced, the corrosion and permeation of the corrosive substances on the outer wall of the pier are reduced, and the service life of the pier is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of cleaning devices, and in particular relates to a cleaning device for the outer wall of an assembled bridge pier. Background technique [0002] Bridge piers are the intermediate support structures in bridges with two spans or more than two spans, except the abutment at both ends connected to the embankment. Bridge piers are divided into solid piers, column piers, and bent piers. According to the plane shape, it can be divided into rectangular piers, pointed piers, round piers, etc. The materials of building piers can be wood, stone, concrete, reinforced concrete, steel and so on. Bridge piers are the necessary supporting conditions for bridge traffic. Assembled bridge piers are different from cast-in-place piers. During transportation, installation or use of fabricated bridge piers, the outer wall surface will inevitably be damaged to some extent, forming some small grooves or When the river is flooded,...

Problems solved by technology

Bridge piers are the necessary supporting conditions for bridge traffic. Assembled bridge piers are different from cast-in-place piers. During transportation, installation or use of fabricated bridge piers, the outer wall surface will inevitably be damaged to some extent, forming some small grooves or When the river is flooded, most of the pier is in deep water. When the water recedes, many corroded substances will remain in the grooves on the outer surface of the pier, and these corroded substances will invade the concrete gap or In the cracks, some studies have found that this method has become one of the major causes of corrosion of bridge piers. Therefore, the surface of bridge piers needs to have strong corrosion resistance. However, the surface of traditional bridge piers is often in a state of natural air-drying, and no one cleans them. , so the anti-corrosion effect is poor, resulting in a relatively low service life of the pier, and in severe cases, it will lead to traffic paralysis
