Description

Special current-collecting drainage device for treating water damage of underground roadway

Technical Field

The utility model relates to a mass flow drainage guide device, in particular to a special mass flow drainage guide device for underground tunnel water damage treatment.

Background

When a tunnel is constructed in underground mining, water damage conditions such as karst fissure water, a marble aquifer, fissure zone water seepage and the like are frequently encountered. The general treatment method is as follows: waterproof layers are paved around the roadway and poured with concrete to isolate flood disasters, or drainage pipes are arranged at water seepage points and led to drainage ditches. The unconventional treatment method comprises the following steps: grouting method, freezing method, blasting extrusion method, etc., but the cost is high, the cycle is long, and the method is suitable for water plugging of large aquifer.

The waterproof layer casting concrete water-insulation method has the following defects:

1. the cost is high and the engineering quantity is large. The cost of casting concrete in the underground roadway is not lower than 1000 yuan per m, the cast concrete needs to completely cover the flood area and exceed a certain distance, and the flood can be effectively isolated by continuously casting concrete for several meters or even tens of meters.

2. The process is complicated and the material is used in a large amount. The waterproof layer needs to be fixed by manual paving, and then the procedures of arch centering, formwork erection, reinforcement framework laying, concrete pouring, vibration, maintenance, formwork removal and the like are carried out. The materials such as waterproof materials, cement, sand, vibrating rods, templates, reinforcing steel bars, arch frames and the like are used, and time, labor and materials are wasted.

3. Difficult to be circulated and easy to be out of service. After concrete is poured, the concrete body is fused with the roadway bedrock, and when the next flood spot is met, additional concrete pouring and water isolation are needed. The concrete body is a rigid body, and after deformation occurs due to underground blasting vibration, original rock ground pressure and the like, the waterproof effect is affected and even fails.

The drainage method has the following defects:

1. the effect is general, and the material is changeable. In some mines, sheet iron, plastic films, PVC pipes and the like are fixed on a roadway water outlet point to isolate water, but the situations of water leakage at the seam of the sheet iron, leakage of the films and the pipelines and the like often occur, and the drainage effect is poor.

2. The turnover is difficult and not smart. Whether the material is made of iron sheet or plastic film, the material is generally fixed around a roadway water outlet point by bolts, and the material is damaged greatly by being taken down again, is difficult to be used for the next water outlet point and is difficult to turnover. The material needs manual handling, cutting, fixing and the like, and the length, the area and the like of the material are large.
