Abstract

The invention provides a hoop-type hydraulic climbing formwork system and a construction method for the construction of a cylindrical pier, in view of the damage to the exterior of the pier caused bythe pre-embedding of the climbing cone in the concrete of the pier body during the construction of the existing column pier climbing formwork, and the climbing precision is difficult to be controlled.The upper and lower hug hoops are installed on the cylindrical pier, and the hug hoop is used as the support structure of the climbing form instead of the climbing cone, and the climbing cone is notembedded in the pier body when pouring, so that the appearance of the pier column can be effectively ensured, the climbing height of the formwork can be flexibly controlled, and the construction quality can be improved. The invention has the advantages of simple working procedure, fast construction speed and high construction safety.

Description

technical field [0001] The invention belongs to the technical field of bridge construction equipment for construction engineering, and in particular relates to a hoop-type hydraulic climbing formwork system and a construction method for construction of bridge column piers. Background technique [0002] In the construction process of cylindrical piers, for the pier columns with high height, the traditional construction method of scaffolding is used for pier column construction, which has technical problems such as long erection time, low efficiency, and high safety risks, such as pier columns located in water or In the environment with poor foundation conditions, the construction cost and construction period will be greatly increased, so it is suitable to use slipform construction. However, the traditional sliding form construction method requires pre-embedded climbing cones in the poured concrete to fix the sliding form brackets and climbing guide rails. This increases the ...
