Description

Technical Field

[0001] The utility model relates to the technical field of grouting and filling, in particular to a grouting and filling device for overburden rock separation layer. Background Art

[0002] During the movement of the overburden, there will be a delamination zone, that is, during a certain period of the dynamic process of the overburden movement, there is a delamination zone composed of multiple delamination layers above the water-conducting fracture zone, which can be used for grouting. The engineering control method of using grouting technology in the delamination zone inside the overburden to slow down the surface subsidence is an effective method to control the surface subsidence. First, drill a hole from the ground into the overburden, and inject grout into the delamination space from the drill hole, thereby inhibiting the continued destruction of the rock mass above the delamination space.

[0003] In the prior art, conventional overburden separation grouting and filling devices lack filtering and crushing functions during use. The presence of coagulants or large particles of raw materials in the slurry can easily cause blockage of the slurry outlet holes. The slurry in the grouting pipe will also have coagulation problems. There is also a lack of cleaning function at the slurry outlet holes, which causes slurry coagulation and other particles to block the slurry outlet holes. When the grouting pipe is inserted into the overburden, it is blocked by obstacles, making the insertion of the grouting pipe time-consuming and labor-intensive, and very inconvenient to use.

[0022] In this embodiment, the mechanical seal 15 provides a better sealing effect between the rotating shaft 9 and the upper side of the sealing cylinder 6 and the lower side wall of the grouting pipe 2, and is not prone to leakage.

[0023] Specifically, the crushing mechanism 10 includes a filter screen 101, an arc groove 102 and a crushing blade 103. There are two filter screens 101 on the left and right. The filter screen 101 is clamped and fixed on the upper surface of the mounting plate 1 and the lower surface of the sealing cylinder 6. The filter screen 101 is a semicircular structure, and a breathing portion is provided on the side of the filter screen 101 close to the rotating shaft 9. The crushing blade 103 is fixedly installed on the outer surface of the rotating shaft 9 on the upper side of the filter screen 101.

[0024] In this embodiment, the left and right filter screens 101 are spliced ​​into a circular filter assembly to filter the slurry entering through the liquid inlet pipe 7, filter the condensate or large particle raw materials, and the crushing blade 103 rotates with the rotating shaft 9 to crush the condensate or large particle raw materials.
