Cast-in-place pile hole side wall reinforcing device

Abstract

The invention relates to a cast-in-place pile hole side wall reinforcing device. The cast-in-place pile hole side wall reinforcing device comprises a lifting mechanism, wherein the lifting mechanism is connected with a driving mechanism; the driving mechanism is connected with an inner tube and an outer tube which are vertically and coaxially arranged, and can drive the inner tube and the outer tube to synchronously and reversely move in the axis direction of the inner tube and the outer tube; the inner tube is inserted in the outer tube and is slidably connected with the outer tube; the outer tube is hinged to one end of a first hinge rod; the other end of the first hinge rod is hinged to a connecting plate; the connecting plate is hinged to one end of a second hinge rod; the other end of the second hinge rod is hinged to the inner tube; the connecting plate is detachably connected with a reinforcing element through a connecting component; and the reinforcing element is used for reinforcing soil of a pile hole. By the reinforcing device, hole collapse is avoided effectively, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of underground engineering construction equipment, in particular to a reinforcement device for the side wall of a cast-in-place pile hole. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Large-diameter pile foundations are generally deep, and because the pile foundation passes through complex strata, problems such as hole collapse are more likely to occur in areas with poor geological development. At present, methods such as mud retaining walls or steel sleeves of a certain length are generally used to deal with it, but the inventors have found that when using mud retaining walls or steel sleeves to reinforce the pile holes of large-diameter pile foundations, due to the deep depth of the pile holes, More reinforcement materials are used, which increases the construction cost, but ...

AI Technical Summary

Problems solved by technology

[0003] Large-diameter pile foundations are generally deep. At the same time, because the pile foundation passes through complex strata, problems such as hole collapse are more likely to occur in areas with poor geological development.

At present, methods such as mud retaining walls or steel sleeves of a certain length are generally used to deal with it, but the inventors have found that when using mud retaining walls or steel sleeves to reinforce the pile holes of large-diameter pile foundations, due to the deep depth of the pile holes, More reinforcement materials are used, which increases the construction cost, and only the set part of the pile hole has bad geology, thus causing a waste of reinforcement materials
