Problems solved by technology
[0005]
In order to solve the above-mentioned technical problems, a tunnel mud inrush disaster control equipment and its method according to the present invention are used to solve the lack of mud pumping design in the prior art, it is difficult to perform rapid grouting, and the initial grouting may be blocked by water pressure question
[0006]
Further, in order to solve the problem that it is not easy to compact and cover the mud intrusion position in the prior art and form a sealing effect, the pressure design is used to make the deformed pressure plate pressed against the tunnel wall to seal

The invention discloses tunnel mud burst disaster treatment equipment and method. The equipment part comprises a tank body, a spiral conveying grouting mechanism and a deformation pressing disc. One end of the spiral conveying grouting mechanism is connected with the tank body, the deformation pressure disc is arranged at the other end of the spiral conveying grouting mechanism, the working angle of the spiral conveying grouting mechanism can be adjusted relative to the tank body, and the relative height between the tank body and the earth surface can be adjusted. According to the tunnel mud burst disaster treatment equipment and method, the structure is reasonable and reliable, mud can be pumped, during preliminary grouting, mud water in the deep position inside is pumped, mud water gushing during grouting is reduced or prevented, grouting plugging is facilitated, meanwhile, the deformation pressing disc is arranged, a filling position can be provided for the later period of grouting, and the filling and plugging effect outside the grouting part is improved, so that the overall grouting and plugging effect is improved.
Description
technical field [0001] The invention is applied in the field of mud inrush disaster control, and in particular relates to a tunnel mud inrush disaster control device and method. Background technique [0002] Tunnel mud-outburst accidents are mainly caused by the sudden collapse of the critical surface in the large karst cavity in front of the tunnel face or around the excavation contour during the construction process, resulting in geological disasters of tunnel mud-outburst [0003] In the existing patent document "CN204283443U vertical mixing and grouting integrated machine", although grouting can be performed, it lacks a mud pumping design, and it is not easy to perform rapid grouting. The initial grouting may be blocked by water pressure, and the grouting effect It may not be good, and at the same time, it is not easy to leave a large-scale and large-area blockage on the tunnel wall after grouting. Still do not have a kind of reasonable and reliable structure and can ca...
