In the actual construction process, each unit groove section of the constructed underground diaphragm wall has great influence, once a problem occurs, great cost and construction period are needed for repairing or reworking, and the construction process is quite uneconomical. And the construction of the underground diaphragm wall needs a lot of heavy equipment, and the entering and exiting field and the construction preparation work are time-consuming and labor-consuming, so that the economic benefit is not high when the engineering quantity is too small. In the experimental simulation of the underground continuous wall, the configuration of the underground continuous wall is generally carried out step by step, but errors in various settings are easy to occur in the process and need to be adjusted.

Disclosure of Invention

The invention aims to provide a self-digging underground continuous wall simulation device for overcoming the defects of large influence of various errors on precision and incapability of being used repeatedly in the prior art.

The purpose of the invention can be realized by the following technical scheme:

the utility model provides a from digging formula underground continuous wall analogue means, includes the fixed body, lift module, rotating electrical machines, cuts native shell and controller, lift module and rotating electrical machines are connected with the controller and are controlled by the controller, lift module's both ends are fixed in on the fixed body, rotating electrical machines locates the lift module top, cut the native shell including cutting the native shell and removing the inner shell, remove the side sliding connection of inner shell and lift module, cut native shell and be connected to rotating electrical machines.

The structure of the fixing body is a cuboid structure.

Preferably, the number of the lifting modules is 2, and the 2 lifting modules are symmetrically arranged at two ends of the long edge of the fixed body.

The structure of the soil cutting shell is an annular structure.

Preferably, the soil cutting shell is provided with a plurality of soil cutting sheets.

The distance between the soil cutting pieces is equal.

The distance between the lifting module and one end of the fixing body close to the lifting module is greater than the length of the soil cutting piece.

Compared with the prior art, the invention has the following beneficial effects:

1. according to the invention, the lifting module, the rotating motor and the soil cutting shell are arranged on the fixed body at a certain distance, and the soil cutting shell can complete the arrangement of the soil cutting and the underground diaphragm wall while deeply cutting, so that the working efficiency of construction is improved.

2. The invention can independently control the two soil cutting shells through the controller according to the requirements of actual terrains, thereby increasing the adaptability of the device to various terrains.

3. The invention is provided with a plurality of soil cutting pieces, so that the excavating capacity of the device is improved, and meanwhile, the length of the soil cutting pieces is smaller than the distance between the lifting module and one end of the fixing body close to the lifting module, so that the soil cutting pieces are prevented from being influenced by the fixing body in the operation engineering.

4. After the earth excavation and the underground continuous wall are arranged, the device is reset by controlling the lifting module to move towards the other end, so that the device can be repeatedly used in a construction site, and the economy of the device is improved.

Detailed Description

The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1, a from formula underground continuous wall analogue means that digs, including the fixed body 1, the lifting module 2, the rotating electrical machines 3, cut the soil shell and controller, the lifting module 2 and the rotating electrical machines 3 are connected with the controller and are controlled by the controller, the both ends of lifting module 2 are fixed in on the fixed body 1, the rotating electrical machines 3 is located the top of lifting module 2, cut the soil shell including cutting the soil shell 5 and removing inner shell 4, remove the side sliding connection of inner shell 4 and lifting module 2, cut the soil shell 5 and be connected to rotating electrical machines 3.

The fixing body 1 and the earth-cutting housing 5 are made of steel structures.

The structure of the fixing body 1 is a rectangular parallelepiped structure.

The number of the lifting modules 2 is 2, and the two ends of the long edge of the fixed body 1 are symmetrically arranged on the 2 lifting modules 2.

The structure of the soil cutting shell is an annular structure.

As shown in fig. 2, a plurality of soil-cutting blades 6 are provided on the soil-cutting housing 5, and the spaces between the soil-cutting blades 6 are equal.

As shown in fig. 3, the distance between the single lifting module 2 and the end of the fixed body 1 adjacent thereto is greater than the length of the soil cutting blade 6.

Example one

Constructor places the solid 1 in the foundation ditch department that needs dig deeply, is cut native shell 5 rotation by the rotatory drive of controller control rotating electrical machines 3, cuts the soil layer 6 and begins to cut the soil layer, and lifting module 2 sends the slip with removing the inner shell under the control of controller after the cutting of current soil layer is accomplished, cuts native shell 5 and moves down, cuts the more dark soil layer of piece 6 continuation cutting, and the setting of digging and underground continuous wall is accomplished until lifting module 2 removes to the end of cutting the soil shell. If an underground continuous wall needs to be built in the trapezoid with the gradient, the two soil cutting shells are independently controlled, and the arrangement of the trapezoid underground continuous wall can be completed when the downward moving depths of the lifting modules are different.
