Auxiliary device for construction barricade and method of constructing barricade of auxiliary device

Abstract

The invention discloses an auxiliary device for construction a barricade and a method of constructing the barricade of the auxiliary device. The auxiliary device comprises a bottom plate and top platemine rocks. Stand columns are arranged between the bottom plate and the top plate mine rocks. The bottom ends of the stand columns extend into fixing holes excavated in the bottom plate in advance. Aplurality of supporting parts arranged obliquely are arranged between the bottom ends of the stand columns and the bottom plate. The auxiliary device further comprises carrier top fixing nuts and a plurality of following rods which are connected in a head-to-tail manner and are connected detachably. The following rods located at the head end and the tail end are detachably connected with the stand columns and the carrier top fixing nuts. The auxiliary device is simple in structure and wide in application range, the requirements for constructing the barricade with the top plate mine rocks of different heights can be met, the method of adopting the auxiliary device for constructing the barricade is simple and high in operability, in the filling process, when the stand columns are filled, the lateral bearing ability is high, and safety and the construction efficiency of barricade constructing are improved.

Description

technical field [0001] The invention relates to the technical field of mining and mining, in particular to an auxiliary device for constructing a retaining wall and a method for constructing a retaining wall with the auxiliary device. Background technique [0002] With the gradual depletion of shallow buried and easy-to-mining mineral resources, the contradiction between the ever-growing demand for mineral resources and the difficulty of resource mining and the pressure of safety and environmental protection has become more and more prominent. The filling mining method has played an important role in solving this contradiction. It is widely used in the field of mining because of its characteristics of safe operation, delaying surface subsidence, and effectively preventing engineering geological disasters such as deep rockbursts. In the filling mining process, the construction of the filling retaining wall is an important work that must be completed before filling. The constr...

AI Technical Summary

Problems solved by technology

The retaining wall still has the following disadvantages during construction: 1) The column is not suitable for the construction of the retaining wall when the height of the top rock is inconsistent, so that the scope of application of the retaining wall is narrow; 2) When the retaining wall is constructed, the column is used Concrete is poured underground. After the construction is completed, the column is not easy to disassemble, and it is easily damaged after disassembly from the concrete, which reduces its compressive capacity and is not suitable for repeated use, which increases the cost of retaining wall construction and reduces the reuse of materials. 3) One end of the support bar of the retaining wall is directly in contact with the bottom plate. When the lateral pressure of the retaining wall is too large during pouring and filling, it is difficult for the end of the support bar in contact with the floor to withstand a large lateral force. The pressure is prone to deformation and slippage, and the unstable contact between the column and the top rock can easily lead to the collapse of the retaining wall and the pollution of the underground environment, which poses a great safety hazard

[0004] Therefore, there is an urgent need to provide an auxiliary device to solve the problems of low construction efficiency and collapse of the retaining wall and the difficulty of supporting the auxiliary support device to withstand the large lateral pressure during the pouring process
