Bridge thin-wall hollow pier column construction method

Abstract

The invention discloses a bridge thin-wall hollow pier stud construction method, which relates to the technical field of bridge pier stud construction, and comprises the following steps: construction preparation, pier stud bottom pouring, and installation of a turning and sliding combination system, and the turning and sliding combination system comprises a template system, an operation platform, a lifting system, a construction precision control system and a water and electricity matching system. And the truss is lifted, the formwork structure is in place, the formwork structure is dismounted, in-place pouring is conducted on the formwork structure again, the next cycle is conducted upwards in sequence, and continuous pouring is conducted till pouring of the pier column is completed. The method has the advantages that the characteristics and advantages of all construction methods are integrated on the basis of an existing construction method, the construction method combining overturning and sliding is adopted and improved, an overturning and sliding combination system comprises a formwork system, an operation platform, a lifting system, a construction precision control system and a water and electricity matching system, the defects of formwork sliding and overturning construction are overcome. And the purposes of high construction speed, high safety, guaranteed concrete quality and less investment are achieved.

Description

technical field [0001] The invention relates to the technical field of bridge pier column construction, in particular to a construction method for bridge thin-walled hollow pier column. Background technique [0002] In the landform area between hills and inter-mountain valleys, the terrain fluctuates greatly. When the bridge is built in the landform area between hills and inter-mountain valleys, the lower part of the bridge is usually designed to be higher, and the piers are generally designed as thin-walled hollow piers when they exceed 40 meters. The positioning control of pier column construction is difficult. For high bridge piers, the height of the pier, high center of gravity, high flexibility of the pier body, and high requirements for construction accuracy are its remarkable features. The construction quality of the pier is very high, and if the construction joints of the high pier are not handled properly, it will become the weak point of the pier body. [0003] In...
