Construction device for floor support with ribbed trough

Abstract

The invention relates to a construction device for a floor support with a ribbed trough. Before a foundation pit earthwork is excavated completely, a construction horizontal direction is set on the floor support with the setting depth in a soil body in a foundation pit, the construction device is propelled in the soil body along the horizontal direction so as to form the floor support, the construction device sets the depth in the soil body so as to form a columnar reinforcer, the ribbed trough is arranged between the top surface of the reinforcer and a floor, and a cemented soil slurry in theribbed trough is solidified to form a ribbed plate. The construction device comprises a trough forming propeller, a floor support forming device and an auxiliary power device, wherein the ribbed trough propeller forms the ribbed trough and is used for enabling the device to horizontally move in the ribbed trough without the need to be pulled out from the soil body; and the floor support forming device forms the floor support. By adopting the construction device for the floor support with the ribbed trough provided by the invention, the construction device can be used as a concealed support ofthe bottom of the foundation pit so as to form a support for a fender post wall, so that supporting and pit bottom reinforcing are combined into one; and when the foundation pit earthwork is excavated, an engineering pile can be prevented from being squeezed and broken, and the pit bottom reinforcement is carried out in advance, so that the engineering cost is reduced, soil can be excavated conveniently, the convenience in construction is realized, and the construction period is reduced.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to the technical field of foundation pit engineering, in particular to construction equipment with ribbed ground supports. Background technique [0002] The existing traditional soil reinforcement at the bottom of the foundation pit usually adopts the method of occlusion and lap joint of multiple vertical cylindrical cement-soil reinforcements, which has the following problems: [0003] First of all, the work efficiency is not high. The high-pressure rotary grouting pile driver frequently connects and unloads the drill pipe, frequently moves the machine to reposition, and the work efficiency is low; the mixing pile machine repeatedly stirs up and down, and it also needs to be idle, and the machine is moved frequently, which affects the efficiency. [0004] Second, material waste. When it is necessary to provide horizontal support from reinforcement, such as to prevent en...

AI Technical Summary

Problems solved by technology

The high-pressure rotary grouting pile machine frequently connects and unloads the drill pipe, frequently moves the machine to reposition, and the work efficiency is low; the mixing pile machine repeatedly stirs up and down, and it also needs to be idle, and the machine is moved frequently, which affects the efficiency

[0004] Second, material waste

When it is necessary to provide horizontal support from reinforcement, such as to prevent engineering piles in soft soil from being crushed during earthwork excavation, or to provide horizontal support to the foundation pit wall at the bottom of the pit, the vertical support in the prior art The occlusal overlap of the cylindrical reinforcement body, each protruding arc part (a part of the cylinder) is invalid, and the stirring pile is invalid in the soil above the bottom of the foundation pit, so the existing traditional reinforcement technology does not economy

[0005] In addition, the traditional existing cement-soil reinforcement method produces a vertical cylindrical reinforcement. The mechanical equipment is frequently moved and repositioned in the horizontal direction. It is inevitable that there will be positioning errors and the errors will exist in all directions. When the horizontal support force is provided, the effective section of the reinforced body will be weakened

[0006] In recent years, there are also some reinforcement equipment for horizontal reinforcement, but it is necessary to make a deep and large end well, put the construction equipment completely in the well, and complete it by jacking pipes or making horizontal cement-soil reinforcement, and the end well itself is Reinforcement of the enclosure is required, which is expensive and not economical enough for shallow foundation pit soil reinforcement
