Abstract

The invention discloses an openable skirt type steel reinforcement cage of a reamed pile and belongs to piling building materials. According to the openable skirt type steel reinforcement cage, a reaming section of a pedestal pile has a horizontal expansion function, the reinforced concrete structure forms of the existing rotary expanding piles are changed, and the load capacity of the rotary expanding piles is increased; the steel reinforcement cage is unfolded at the bottom of a hole through a plurality of link mechanisms, the appearance of the unfolded steel reinforcement cage is basically similar to the contour of the reamed hole, the link mechanisms are simultaneously opened and are connected with an existing steel reinforcement cage through steel stranded wires, then, concrete is cast, the link mechanisms serve as steel reinforcement members, and thus, the strength of concrete members of rotary expanding pile bodies is enhanced.

Description

technical field [0001] The invention relates to a steel bar mechanism combination of building reaming piles, in particular to an openable skirt type reinforcement cage of reaming piles. technical background [0002] At present, domestic and foreign engineering and construction widely use rotary drilling rigs as piling machines. However, most of the rotary drilling rigs are vertical hole drills of various diameters. Advanced drilling tools make the concrete pile hole partially enlarged, increase the stability of the structure, and improve the tensile, compressive and bending strength of the pile body. However, there is no reinforcement at the reamed portion, which reduces the strength of the concrete member. Contents of the invention [0003] In order to solve the problem that the part of the reamed hole is not supported by steel bars after the pile hole is partially enlarged, the invention provides an openable skirt-type reinforcement cage for the reamed pile. [0004] T...
