Abstract

The invention discloses a switching device of cast equipment of a concrete bored pile, comprising a hollow steel box (1), wherein the upper end of the steel box (1) is communicated with the lower end of a hopper (2), and the lower end of the steel box (1) is communicated with the top end of a main conduit (3); the steel box (1) is internally hinged with a division plate, the shape and the area ofwhich are matched with those of a cross section in the steel box (1); and the steel box (1) is provided with a position limiting device capable of keeping the division plate in a horizontal state. The switching device of the cast equipment of the concrete bored pile can ensure that the process for pouring concrete for the first time is uniform and continuous and no sandbag is mixed in the concrete in a pile foundation.

Description

technical field [0001] The invention relates to a construction device for pile foundations in civil engineering, in particular to a switch device for pouring equipment for concrete bored piles. Background technique [0002] Concrete bored pile is a pile foundation with holes formed on site and concrete poured on site. Concrete bored piles have the advantages of large diameter, high bearing capacity, and relatively low cost, but they need to use a large amount of mud during construction, and these muds will cause environmental problems when they are discharged. Therefore, the environmental requirements for the construction site are relatively low. In less strict occasions (such as roads, bridges and other projects) concrete bored piles are still commonly used. [0003] The construction of concrete bored piles includes the following processes: [0004] 1. Forming a hole, that is, using a drilling rig to form a hole according to the diameter and depth required by the design, ...
