Problems solved by technology

[0002] The existing viaduct caps mainly adopt the cast-in-place construction mode, which has the advantages of long construction time and large floor area, which seriously affects the normal operation of the city
At the same time, due to the large size of the cap components, the use of overall prefabrication leads to limited transportation in the urban area; the overall weight of the components makes the on-site hoisting construction difficult. Therefore, we propose a new cap structure and construction method

Abstract

The invention discloses a novel bearing platform structure. The novel bearing platform structure comprises a bearing platform and a reinforced concrete anti-shear plate; a pile foundation is connectedto the bottom of the bearing platform; the reinforced concrete anti-shear plate is positioned at the bottom of the bearing platform; the bearing platform comprises a boundary segment and a transitionsegment and a middle segment; axial prestressed tendon hole passages are formed in the boundary segment and the transition segment and the middle segment; concave grooves are reserved in the bottomsof the boundary segment and the transition segment and the middle segment; tendon inserting holes are formed in the tops of the concave grooves; the boundary segment is positioned on one side of the middle segment; and the transition segment is positioned between the boundary segment and the middle segment. According to the novel bearing platform structure, the difficult problems of low construction efficiency and large city operation interference of an existing cast-in-place bearing platform are mainly solved; and meanwhile, by using the prefabricated sub-assembly bearing platform structure,the difficult problem that an ultra-large and superheavy member is hard to transport and hoist as a large-dimension bearing platform is integrally prefabricated at one time is solved.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and in particular relates to a novel bearing platform structure and a construction method. Background technique [0002] The existing viaduct caps mainly adopt the cast-in-place construction mode, which has the advantages of long construction time and large floor area, which seriously affects the normal operation of the city. At the same time, due to the large size of the cap components, the use of overall prefabrication leads to limited transportation in the urban area; the overall weight of the components makes the on-site hoisting construction difficult. Therefore, we propose a new cap structure and construction method. Contents of the invention [0003] The object of the present invention is to provide a novel cap structure and construction method to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the pres...
