Steel structure bridge cofferdam construction equipment capable of mechanically removing steel sheet pile

Abstract

The invention relates to steel structure bridge cofferdam construction equipment capable of mechanically removing a steel sheet pile. The steel structure bridge cofferdam construction equipment comprises a bottom plate, wherein a moving fixing device is mounted at the lower end of the bottom plate, a regulating lifting device is mounted at the upper end of the bottom plate, and a removing clampingdevice is mounted on the regulating lifting device; a placing box is mounted on the bottom plate; and the moving fixing device comprises moving regulating mechanisms which are uniformly arranged at the lower end of the bottom plate, the lower ends of the moving regulating mechanisms are mounted on a moving support plate, a fixing telescopic cylinder is mounted on the moving support plate, and thetop end of the fixing telescopic cylinder is mounted on the bottom plate through a flange. The steel structure bridge cofferdam construction equipment can solve the problem that in the existing process of removing the steel sheet pile during bridge cofferdam construction, the steel sheet pile needs to be manually pulled out by using the existing crane equipment, the steel sheet pile needs to be manually fixed, and the steel sheet pile needs to be manually pulled out under the assistance of a vibrating tool, so that time and labor are wasted. The function of a machine mechanically removing thesteel sheet pile during bridge cofferdam construction can be realized.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to a steel structure bridge cofferdam construction equipment capable of mechanized removal of steel sheet piles. Background technique [0002] The steel sheet pile is a kind of linkage device on the edge, and the linkage device can be freely combined to form a continuous and compact steel structure for retaining soil or water retaining wall. The steel sheet pile is a type of steel with a lock. There are U-shaped and Z-shaped cross sections, and various sizes and interlocking forms. The common ones are Larson type, Lackawanna type and so on. Its advantages are: high strength, easy to drive into hard soil; it can be constructed in deep water, and if necessary, it can be added with oblique supports to form a cage. Good waterproof performance; cofferdams of various shapes can be formed according to needs. It is widely used in steel structure bridge cofferdams. Th...

Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a steel structure bridge cofferdam construction equipment that can mechanized remove the steel sheet piles, which can solve the existing problem in the process of removing the steel sheet piles in the existing bridge cofferdams that need to be manually lifted with the help of existing equipment When the equipment removes the steel sheet piles, it is necessary to manually fix the steel sheet piles and manually transport the removed steel sheet piles. The difficult-to-pull steel sheet piles need to be removed manually with the aid of vibration tools. Manually fixed steel sheet piles have poor stability and pose safety hazards. The steel sheet piles of different specifications need to be manually adjusted accordingly, and the operation is complicated. It is time-consuming and laborious to remove the steel sheet piles manually with the help of vibration tools, which affects the removal of the steel sheet piles. The labor intensity is high, the time is long, and the work efficiency is low. The function of the machine for mechanized demolition of steel sheet piles for bridge cofferdams does not require manual operation, there is no potential safety hazard, and it has the advantages of simple operation, time saving, good stability, high labor intensity and low work efficiency.
