Background
The mining body can form a goaf due to mining, so that in order to prevent the earth surface from sinking, the hidden production trouble is eliminated, and the safety of operators in the pit is ensured, so that the goaf needs to be treated timely and timely in a planned manner. When the goaf is treated, a filling method is often adopted to treat the goaf, and a filling wall is an essential link before filling after mining.
In the prior art, a wall body is often poured by cement concrete, one side of the wall body is covered with a layer of non-woven fabric, a layer of reinforcing steel mesh is arranged in the poured wall body, and after the concrete is completely condensed, the filling wall is represented to finish construction. However, the filling wall generally formed by pouring reinforced cement only has low strength, and when the earth surface falls, the surrounding is pressed due to insufficient bearing capacity, cracks are easy to generate, and even the wall collapses.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provide the high-strength mine filling wall capable of resisting the gravity of the subsidence of the ground surface and effectively ensuring the safety of operators in a pit.
The technical scheme adopted by the utility model for solving the technical problems is that the high-strength mine filling wall comprises a rigid surface, a filling body and a flexible surface, wherein the rigid surface is connected with one surface of the filling body, and the flexible surface is connected with the other surface of the filling body.
By adopting the technical scheme, the rigid surface is arranged as a first layer of protection against the gravity of the earth surface collapse, the filling body is arranged as a second layer of protection against the gravity of the earth surface collapse, and the inner flexible surface enables the compressive strength in the whole wall body to be high and the buffering performance to be high.
When the larger collapse condition occurs, the flexible surface can lighten the pressure brought by the earth surface collapse and the outer wall body to the internal operators to a certain extent, and a certain buffering force is given to the human body, so that the possibility that the operators are survived in the rescue process is higher.
Further, the center of the filling body is provided with a reinforcing column, two sides of the reinforcing column are symmetrically provided with bearing plates, and the outer sides of the bearing plates are provided with reinforcing bars.
Through adopting above-mentioned technical scheme, set up the spliced pole and make the stability between two bearing plates higher, set up the bearing plate and accept the pressure that the earth's surface brought, the setting of reinforcing bar makes the intensity of whole packing body higher.
Further, the rigid face is the outermost side of the infill wall, and the flexible face is the innermost side of the infill wall.
By adopting the technical scheme, the rigid surface can resist the gravity brought by the earth surface at the outermost side, and the flexible surface can effectively protect the safety of operators at the innermost side.
Furthermore, concrete pouring is adopted between the two bearing plates, between the bearing plates and the rigid surface and between the bearing plates and the flexible surface.
By adopting the technical scheme, concrete is poured between the two bearing plates, so that the concrete and the two bearing plates form a bearing column, the strength of the whole wall is higher, concrete pouring is adopted between the bearing plates and the rigid surface and between the bearing plates and the flexible surface, the concrete is solidified with the reinforcing steel bars between the bearing plates and the rigid surface and between the bearing plates and the flexible surface after solidification, and the integral strength is higher.
Compared with the prior art, the utility model has the following beneficial effects: the first layer protection of setting up the rigidity face as the gravity of keeping out the earth's surface and falling, the filler is as the second floor protection of keeping out the gravity of earth's surface and falling, and the flexible face in makes compressive strength and buffering performance in the whole wall body improve, lightens the earth's surface and collapses and the outer wall body to a certain extent and bring to the pressure of inside operating personnel, gives certain buffering power to the human body for operating personnel is later in the in-process of rescue possibility more, effectively ensures the safety of operating personnel in the hole.
