Problems solved by technology

[0003] For tunnels passing through water-rich ground or weak interlayers, the risk of water inrush during construction is currently extremely high
In particular, local water gushing accidents occur. Although such accidents affect a small area, due to the special geological structure environment, the water consumption in a short period of time is extremely large.
If the local water gushing is not blocked, it is easy to cause a wider range of accidents, which will have a huge negative impact on the progress of the project and construction safety.
At present, the common method is to use sandbags to block the working face, and then carry out grouting reinforcement. This process is very dangerous, heavy workload and time-consuming. During this process, the sandbags completely block the working face, which also makes it impossible for rescuers to deal with the problem. Collect and analyze the source and pressure of water gushing to affect accident analysis and subsequent construction progress

Embodiment 1

[0057] in as Figure 1-5 In the illustrated embodiment 1, the embodiment 1 provides a local water gushing protection device for a tunnel, which is used to block a local water gushing working face of the tunnel, and the water gushing protective device includes a lifting device, at least two first support rods, Guide rail 2, slider 6, at least two second support rods and waterproof cloth; the first end of the lifting device is rotatably installed on the tunnel floor 19, and the second end of the lifting device is slidably connected to the guide rail 2 , the first end of each first support rod is rotatably connected to the second end of the lifting device, the second end of each first support rod is rotatably connected to the first end of each second support rod, The slider 6 is slidably connected to the guide rail 2, and the second end of each second support rod is rotatably connected to the slider 6, wherein at least one set of the first support rod and the second support rod a...

Embodiment 2

[0108] like Figure 6-8 As shown, Embodiment 2 provides a tunnel local water gushing protection device for blocking the local water gushing working face of the tunnel, and the water gushing protective device includes a jack 8, 4 outer steel rods 1, a guide rail 2, a slider 6. 4 inner layer steel rods 5 and outer layer high-strength waterproof cloth 3 (not shown); the first end of the jack 8 is rotated and installed on the tunnel ground 19 through the ground anchor 16, and the second end of the lifting device It is rotatably connected to an outer steel rod 1 , that is, the second end of the lifting device is rotatably installed in the rotation shaft installation notch 121 of an outer steel rod 1 to avoid interference.

[0109] An outer steel rod 1 is provided with a sliding end 111, the sliding end 111 is slidably connected to the guide rail 2, the first end of each outer steel rod 1 is rotatably connected to the sliding end 111, and the outer steel The second end of the rod 1...

Embodiment 3

[0111] like Figure 9 As shown, the outer high-strength waterproof cloth 3 is provided with a valve 12 for opening and closing the drainage hole 10 . Before installing the device, the valve 12 on the drain hole 9 should be closed to prevent water gushing, so that it is safer to use. The valve 12 is provided with a tightening bolt 121 for opening and closing the valve 12 , and a hole pressure sensor 122 is provided at the valve 12 .

[0112] like Figure 10 As shown, the outer layer of high-strength waterproof cloth is provided with a one-way valve 3. The one-way valve includes a gate 14 and a gate fastener 15. The gate fastener 15 is fixed in the grouting hole 10. One end of the gate is connected with the inner surface of the grouting hole 10 through the rotating shaft 13, and the other end of the gate 13 is in contact with the side of the gate fastener 14 facing the inner end of the grouting hole 10. When grouting is required, the slurry Enter from the outer end of the gro...

Abstract

The invention relates to a tunnel partial water inrush protection device and a method of using the same, comprising a lifting device; the lifting device rotates on the tunnel floor, the lifting device slides on a guide rail, each first support rod rotates on the lifting device, and each first support rod rotates on each The second support rod, the slider slides on the guide rail, each second support rod rotates on the slider, and at least one hinge point of the first support rod and the second support rod rotates on the ground, in the use state, each second support rod and the tunnel are partially flooded with water The working surfaces are arranged opposite to each other. When the lifting device drives it to slide on the guide rail, each first support rod forms a first umbrella-shaped space, and the waterproof cloth is wrapped and arranged in the first umbrella-shaped space. The invention has the advantages of simple structure, ingenious design and convenient installation. The umbrella-holding method is applied to effectively protect the local water gushing in the tunnel, and the operation is easy, and the water gushing in the local working face in the tunnel can be blocked faster; The collection and analysis of water inrush sources and pressure will not affect accident analysis and subsequent construction progress.

Description

technical field [0001] The invention relates to the technical field of tunnel water gushing prevention technology, in particular to a tunnel local water gushing protection device and a method for using the same. Background technique [0002] The local water influx in the tunnel is due to the destruction of the surrounding rock aquifer structure due to the tunnel excavation operation, resulting in a sharp change in the mechanical balance between the hydrodynamic conditions and the surrounding rock, causing the energy stored in the groundwater to migrate instantaneously in the form of high-speed fluid. A phenomenon of release. The principle of tunnel water inrush treatment is the combination of "prevention, drainage, interception and blocking", and at the same time, taking into account the impact on the surrounding environment, the governance concept of "combining drainage and blocking, focusing on blocking" is adopted. [0003] Currently, for tunnels traversing water-rich fo...
