Problems solved by technology

This greatly limits the scope of goaf governance
[0006] When there is water in the goaf and the slurry transport distance is long, the water will have a great impact on the properties of the slurry. For dilute slurry, such as slurry composed of fine particles such as cement and fly ash, the addition of water will greatly dilute the original slurry. Some slurry concentration can reduce the stone rate and stone body strength, and affect the grouting effect; for thick slurry, such as concrete and mortar, the addition of water will cause the slurry to segregate and cause pipe blockage, so that the slurry cannot be sent to the area to be treated. bulk material, water will cause the slurry to disperse directly and lose its fluidity

Embodiment 1

[0065] refer to figure 1 , figure 2 , image 3 As shown, a specific embodiment of the present application provides a prefabricated slurry storage device for filling deep underwater confined spaces, including a plurality of storage storage units connected end to end, and each storage storage unit includes a pipe body 1. Plug 2 and plug 3. Each slurry storage unit is relatively independent and detachable threaded.

[0066] The length of pipe body 1 is about 3 meters, preferably cylindrical, and its interior is hollow, has a cavity with the same axial direction. The body 1 includes a first port and a second port. The inner wall of the first port of the pipe body 1 is provided with an internal thread 11, and an annular boss 13 is provided below the internal thread 11. The surface of the annular boss 13 is also provided with a thread 131 for convenience. The plug 2 is connected with the thread of the pipe body.

[0067] In other technical files, the plug 2 can also be fixed on...

Embodiment 2

[0096] In this embodiment, the plug assembly adopts a one-way valve, through which the slurry can only be poured into the goaf from the outside, and at the same time prevents the groundwater in the goaf from seeping into the pipe.

[0097] The outer side of the one-way valve has an outer threaded surface that is rotatably matched with the plug, and the outer threaded surface can be formed on an annular sleeve, and the sleeve is sleeved and fixed on the outer side of the one-way valve.

[0098] The outer threaded surface of the sleeve body can be rotatably matched with the plug 2, and can also be rotatably matched directly with the inner wall surface of the pipe body.

[0099] The one-way valve can be purchased directly on the market, and its principle and structure will not be described in detail.

Abstract

The invention discloses an assembly type slurry storage device for filling a deep underwater confined space. The assembly type slurry storage device comprises a plurality of slurry storage device units connected end to end. Each slurry storage device unit comprises a tube body with a cavity communicating in the axial direction and two plug assemblies which are correspondingly arranged at the two ends of the cavity, and each plug assembly is used for closing or unidirectionally opening one end of the cavity. The invention further provides an assembly method of the assembly type slurry storage device for filling the deep underwater confined space. The assembly type slurry storage device and the assembly method have the advantages that a separate assembly type slurry storage device is filledin the ground, then the assembly type slurry storage device units are connected end to end and are placed into a hole, the contact between slurry and water is effectively blocked, and the problem thatthe slurry cannot be delivered in the underwater environment is solved.

Description

technical field [0001] The invention belongs to the technical field of underground mined-out area treatment, and in particular relates to an assembled slurry storage device and an assembly method thereof for filling underwater deep confined spaces. Background technique [0002] The goaf refers to the mining space formed underground after the underground resources are mined. According to the different mining types and mining methods, the goaf roof shows different failure modes, and the ground surface also produces different deformation characteristics. For example, when using the full subsidence method for mining, the roof of the ore body will continue to collapse with the expansion of the mining area, thereby forming a subsidence basin on the surface, and the destruction of the surface occurs immediately after the mining of the ore body; while for When the non-full sinking method (room-and-pillar) is used for mining, the roof of the ore body is relatively stable. When the or...
