Abstract

The invention relates to a pile mould with draw-pull type movable feed ports and a construction method. A plurality of draw-pull type movable feed ports are arranged on the lateral side of the immersed tube pile mould in the longitudinal direction. Each draw-pull type movable feed port is composed of a rail, an open hole, an arc inserting plate and a movable connector, wherein the open hole is formed in the lateral side of the pile mould, the rail is fixedly connected with the periphery of the pile mould with the open holes, the rail is in a U shape, the inner side of the rail is provided or connected with a waterproof rubber gasket, the movable connector is arranged on the arc inserting plate, the movable connector is in a T shape, the movable connector is hinged to one end of the arc inserting plate, a clamping groove is formed in the bottom of the U-shaped rail, the clamping groove is matched with the movable connector, and the movable connector is inserted into the clamping groove to fix the arc inserting plate. The pile mould overcomes the defects that the feed ports are large in power demand with the increasing height, can damage formed piles and the like. The draw-pull type movable inserting plates are convenient, quick and easy to operate, capable of saving energy, good in sealing performance and high in pile forming quality.

Description

technical field

[0001] The invention belongs to the technical field of civil engineering, and in particular relates to a pile form with a pull-type movable feeding opening and a construction method. Background technique

[0002] Immersed tube pile is a commonly used pile foundation technology in civil engineering. It uses hammering pile driving equipment or vibrating pile driving equipment to sink steel pipes with prefabricated reinforced concrete pile tips or valve-type pile shoes into the soil. In the process, the pile hole is formed, and then the reinforced skeleton is put in and the concrete is poured through the fixed feeding hopper set on the pile formwork, and the concrete is poured while the pipe is pulled out while vibrating, and the concrete is compacted by the vibration during the pipe pulling, and the required concrete is formed. cast-in-place piles.

[0003] Before the present invention, the pipe-immersed cast-in-place piles such as circular sunken pipe piles, ...
