Embodiment 1
[0047] On the basis of the above structure, in this embodiment, step S2 specifically includes the following steps:
[0048] S21: Manually insert a plurality of grouting pipes 3 at intervals in the vertical direction on the upper part of the surface of the slag 1 that has collapsed in the roadway;
[0049] S22: Inject grout into a plurality of grouting pipes 3 in order from bottom to top. In two adjacent grouting pipes 3, when grouting occurs in the upper grouting pipe 3, the grouting pipe below will be grouted. The grouting pipe 3 is closed, and the grouting of the grouting pipe 3 above is started, and the grouting is performed sequentially.
[0050] In this embodiment, grout is injected into a plurality of grouting pipes 3 sequentially from bottom to top. In two adjacent grouting pipes 3, when grouting occurs in the upper grouting pipe 3, the grouting pipe 3 that is being grouted will be The lower grouting pipe 3 is closed, and the grouting of the upper grouting pipe 3 is st...
Embodiment 2
[0053] On the basis of Embodiment 1, in this embodiment, in step S21, three grouting pipes 3 are inserted into the upper part of the surface of the slag 1 that has collapsed in the roadway. The structure is simple and the design is reasonable, ensuring that all parts of the slag 1 are Filled with slurry, so as to ensure the stability of the slag 1 cementation.
[0054] Among them, when grouting and filling the collapsed part of the tunnel vault, single-liquid grouting is used, and the grouting pipe 3 is grouted in order from low to high, and the lower grouting pipe 3 is terminated according to the grouting situation of the upper grouting pipe 3 of grouting. Taking the three grouting pipes 3 as an example, the three grouting pipes 3 from top to bottom become the upper grouting pipe, the middle grouting pipe and the lower grouting pipe; When grouting occurs in the pipe, close the lower grouting pipe 3; then, grout into the middle grouting pipe; when grouting occurs in the upper...
Embodiment 3
[0058] On the basis of Embodiment 1, in this embodiment, one end of each grouting pipe 3 inserted into the slag 1 collapsed in the roadway is in the shape of a pointed cone, with a simple structure and reasonable design, which is convenient for quickly inserting the grouting pipe 3 into the slag. Within 1 stone, saving time and effort.
