Tool type operating platform for pile foundation tremie extension

Abstract

The invention discloses a tool type operating platform for pile foundation tremie extension. The tool type operating platform for pile foundation tremie extension is characterized by comprising an operating platform body and a movable door plate, the operating platform body is formed by fixing channel beams and two anti-skid steel plates, the channel beams form a frame in the shape of three stacked square blocks, and the two anti-skid steel plates are fixed on two sides of the channel beam frame. The movable door plate is composed of two high-strength steel plates, circular pull rings and pin shafts, the outer side edge of each high-strength steel plate is connected with the middle of the channel beam frame through the pin shafts, each pull ring is fixed on the top face of each high-strength steel plate, and semicircles are arranged at inner side contact edges of the two high-strength steel plates to jointly form a circular hole for a tremie to pass through. The tool type operating platform is convenient and efficient to operate and simple and stable in tremie fixation during tremie extension and underwater concrete construction and demolishing, and is recyclable and reusable at various cast-in-place pile heads with different diameters.

Description

technical field [0001] The invention relates to the technical field of building engineering construction; in particular, it relates to a tool-type operating platform for extending concrete conduits of pile foundations. Background technique [0002] During the underwater concrete pouring process of cast-in-situ piles, the length of the conduit is generally fixed by a temporary frame. This method is time-consuming and laborious, the fixation is not firm, and it is dangerous during the construction process. A tool-type operating platform for pile foundation concrete conduit extension can be directly erected at the wellhead, and the operator directly stands on the platform for operation, and the extension and removal of the conduit can be realized by opening and closing the movable door panel. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tool-type operating platform for the extension of pile foundation concrete ...
