Concrete pouring equipment for bridge piers

Abstract

The invention provides concrete pouring equipment for bridge pier columns, which belongs to the technical field of bridge construction and is used to solve the problem of low efficiency of concrete pouring for existing bridge pier columns. It includes a fixing mechanism and a lifting mechanism. The fixing mechanism includes a partition. The lifting mechanism includes four support columns. The four support columns are all fixed on the partition plate. There are a lifting screw and three sliding rods, a lifting motor is fixed under one of the supporting columns, the output shaft of the lifting motor is connected to the lifting screw, a number of supporting rings are fixed between the four supporting columns, and ring grooves are opened on the supporting rings. A rotating mechanism is slidably arranged on the lifting trough, and a knocking mechanism is arranged under the rotating mechanism; the present invention adopts the cooperation of the lifting mechanism, the knocking mechanism and the rotating mechanism, and can vibrate the concrete while injecting concrete inside the partition to improve It improves the efficiency of concrete pouring for bridge piers.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and relates to concrete pouring equipment for bridge piers. Background technique [0002] A double-track bridge generally refers to a bridge with two line tracks and the two line tracks are reversed. Most of the double-track bridges are viaducts. When the viaducts are laid, bridge piers generally need to be poured to span the terrain. When the pier column is poured, the ordinary concrete is not vibrated in time after entering the form, and it cannot be compacted, which will easily lead to problems such as holes, exposed ribs, honeycomb, slag inclusion, etc., which will affect the bearing capacity and safety of the bridge pier column. Use and durability of buildings. [0003] In the existing concrete pouring, staged pouring is often used. The steps are to inject a certain amount of concrete, put the vibrating device in for vibrating, then remove the vibrating device, and inject a cert...

Problems solved by technology

[0002] Double-line bridges generally refer to bridges with two line tracks and the two line tracks are reversed. Double-line bridges are mostly viaducts. When laying viaducts, bridge piers are generally required to cross the terrain. General bridges When the pier column is poured, if the ordinary concrete is not vibrated in time after it is put into the mold, it cannot be compacted, which will easily lead to problems such as holes, exposed ribs, honeycomb, slag inclusions, etc., which will affect the bearing capacity and safety of the bridge pier column. Use and Durability of Buildings

[0003] The existing concrete pouring usually adopts segmental pouring. The steps are to inject a certain amount of concrete, put the vibrating device into it for vibrating, then remove the vibrating device, and inject a certain amount of concrete again, which leads to the inability to synchronize during the construction process. Vibration, it is necessary to wait for the concrete injection to be completed when pouring the bridge pier column, and then vibrate it, which leads to a low efficiency of concrete pouring of the bridge pier column. At the same time, the concrete on the inner wall of the template is easy to stick, resulting in the concrete The internal coarse aggregate is unevenly distributed, therefore, we propose an efficient concrete pouring equipment for bridge pier columns
