Movable construction platform for bridge foundation building

Abstract

The invention provides a movable construction platform for bridge foundation building. The movable construction platform for bridge foundation building comprises floating bodies, horizontal support frameworks, horizontal backing plates, a lifting system, temporary fixing devices and support body systems; the horizontal support frameworks are laid on the upper surfaces of the floating bodies, the horizontal backing plates are laid on the upper surfaces of the horizontal support frameworks, filling pile holes formed according to bridge foundation building are formed in the horizontal backing plates, the lifting system is erected on the horizontal backing plates, and the support body systems are arranged on the peripheries of the floating bodies; each support body system comprises an anchor head, a support leg, support seats, hydraulic lifting equipment and bolt pins, wherein bolt pin holes longitudinally extending in a separated mode are formed in the support leg, through holes correspondingly communicated with the bolt pin holes are formed in the support seats, and the bolt pins are correspondingly inserted into the bolt pin holes and the through holes which are communicated with each other. The movable construction platform for bridge foundation building has the advantages that the platform can be steadily and firmly fixed on the construction water surface, cannot be shaken under the influences of tides or waves when construction is performed and is suitable for arrangement of various filling piles in bridge building; in addition, the size of the platform can be regulated, and construction is easy.

Description

Technical field [0001] The invention belongs to the field of construction platforms for bridge infrastructure construction in water, and in particular relates to a movable construction platform for bridge infrastructure construction. Background technique [0002] The rapid development of today's society has promoted the widespread rise of basic engineering construction, and the construction of bridges is also increasing. When building a bridge in deep water, large-diameter cast-in-place piles are generally used as the pier foundation of the bridge. During construction, it is easy to be restricted by water depth, flooding, navigation, etc., so it is necessary to set up a temporary construction platform to eliminate construction interference and solve precise positioning And other issues. In view of the existing bridge deep-water pile foundation construction platform, the use of fixed construction platform can no longer meet the construction needs. [0003] Due to the difficulty of...

AI Technical Summary

Problems solved by technology

However, in the process of actual use, the above-mentioned traditional floating platform construction foundation has defects that are greatly restricted by geographical conditions. When water transportation such as reservoir areas and dam areas is underdeveloped, and large barges cannot enter, this floating platform construction plan cannot be used. Meet construction requirements

However, in the coastal or inner river waters with developed traffic, it is greatly affected by tides or waves, and floating on the water will cause the platform to shake and become unstable, which will affect the construction
