Problems solved by technology

[0002] During the excavation process of the roadway using the hand bag drill, the roadway is under the influence of relatively complex geology, water gushing in the roadway, roof collapse and other phenomena occur, and the surrounding rock of the roadway collapses in case of water collapse. It is difficult to pass a single This support method passes through this section of the area smoothly. If the construction detour is adopted, the cost required is high, the roadway for re-construction is long, and the construction period is seriously affected.
[0003] In order to solve this problem, the existing technology adopts: due to the complexity of the surrounding rock on site, it is difficult to pass according to the current construction technology, and it affects the construction period. In order to ensure construction safety, the roadway in the collapsed section is abandoned and the roadway is re-diverted. , according to the geological occurrence, the corresponding support work should be done in advance for the newly diverted roadway
The existing technology has the following disadvantages: the abandoned roadway is long, and the newly diverted roadway has a large engineering volume, high cost, and long impact on the construction period

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.

Abstract

The invention relates to a well and lane engineering treatment method under complex engineering geological conditions. The well and lane engineering treatment method specifically comprises the following steps that concrete is sprayed to the surface of the lower part of slag stone collapsing in a laneway to form a grouting rock cap; and grouting is carried out on the upper part of the dropped slag stone of the roadway. The well and lane engineering treatment method under the complex engineering geological conditions has the beneficial effects that safe and effective passing through the section of dangerous area under the conditions of water burst and collapse of the roadway is realized in the mode of grouting, advanced pipe shed, concrete support, steel bracket support and the like; and according to the construction mode, the grouting and water plugging process is flexibly applied, concrete spraying supports are used as grouting rock caps of caving surrounding rocks, the ultrahigh grouting technology is used, caved slag stones are cemented together to serve as a base for grouting of the top of the roadway, a good foundation is laid for grouting of the top of the roadway, and safe construction is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering treatment, in particular to a tunnel engineering treatment method under complex engineering geological conditions. Background technique [0002] During the excavation process of the roadway using the hand bag drill, the roadway is under the influence of relatively complex geology, water gushing in the roadway, roof collapse and other phenomena occur, and the surrounding rock of the roadway collapses in case of water collapse. It is difficult to pass a single This support method passes through this section of the area smoothly. If the construction detour is adopted, the cost required is relatively high, the roadway for re-construction is long, and the construction period is seriously affected. [0003] In order to solve this problem, the existing technology adopts: due to the complexity of the surrounding rock on site, it is difficult to pass according to the current construction technol...
