Suspension box body bearing platform foundation construction trestle and construction method

Abstract

The invention discloses a suspension box bearing platform foundation construction trestle and a construction method. The trestle comprises trestle sections and an upper structure laid on the trestle sections. The trestle segments are formed by splicing a plurality of suspension box body bearing platform foundations through truss connecting pieces; each suspension box bearing platform foundation comprises a plurality of supporting assemblies and a lower structure, and the supporting assemblies are fixed to the lower structures. The lower structure comprises a suspension box body bearing platform and a plurality of fixing cables used for fixing the suspension box body bearing platform. The suspension box body bearing platform is of a hollow box body structure and comprises a box body and a cover plate arranged on the box body in a sealing and covering mode, and a vent hole and a water injection and drainage hole are formed in the box body. The interior of the box body is divided into cavity arrays by transverse partition plates and longitudinal partition plates, drainage holes are formed in the bottoms of the transverse partition plates and / or the longitudinal partition plates of the edge cavities, and water inlet channels are arranged between the non-edge cavities and the adjacent edge cavities. The method can reduce the high engineering cost, and solves the problems that the water environment is polluted and the water level cannot be adapted to rapid change.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a trestle bridge and a construction method for the foundation construction of a suspension box bearing platform. Background technique [0002] With the rapid development of infrastructure construction in my country, the construction of bridges spanning deep, long and large waters is increasing. In bridge construction, in order to solve the problems of personnel passage and transportation of construction facilities during the construction of bridge piles, the construction of bridges in deep water areas and high water and deep sea areas usually requires the construction of a construction trestle parallel to the axis of the main bridge before the main construction. The construction trestle is used for Mechanical equipment input, material and personnel transportation. The current water construction trestle usually uses sinking steel pipe piles as the substruc...
