[0002] Tunnel construction water gushing refers to the phenomenon that groundwater enters the tunnel through the tunnel wall, stratum cracks or other infiltration channels during the tunnel construction process. In order to gain time for subsequent rescue and drainage work, water retaining structures are usually set up in the direction of water flow in the tunnel to block it.

[0003] At present, the existing water retaining structures used to prevent water gushing into tunnels have weak thrust resistance. When the impact of the gushing water is large, the water retaining structures are easily washed away by the water flow and lose their water retaining capacity, thereby causing scouring and erosion of the rock and soil around the tunnel, which can easily lead to safety accidents.

[0004] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention. The terms "connected" and "connected" used in the present invention should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0030] Embodiment: This embodiment aims to provide a tunnel water inrush blocking device, the main function of which is reflected in its extremely strong and stable anti-slip ability, which can withstand strong tunnel water inrush and prevent the rock and soil around the tunnel from being scoured and eroded.

[0031] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6The trolley case 3 is a pair of vertical trolley cases 1, and the trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The trolley case 3 is a pair of vertical trolley cases 1. The water baffle 3 is swung toward the direction of the water gushing from the tunnel so that the middle part of the water baffle 3 is concave toward the direction of the water gushing from the tunnel, so that the water pressure is first gathered toward the middle part of the water baffle 3. A support frame is provided between the middle part of the water baffle 3 and the hinge of the two shaping plates 1. The support frame includes: a front pressure plate 7, a support arm 8 and a rear pressure plate 9. The front side of the front pressure plate 7 is tightly attached to the middle part of the water baffle 3, the front end of the support arm 8 is fixedly docked with the middle part of the rear side of the front pressure plate 7, and the rear end of the support arm 8 is fixedly docked with the front side of the rear pressure plate 9. The two rear plate edges of the rear pressure plate 9 are respectively against the front of the two shaping plates 1. After the front of the water baffle 3 is pressurized, pressure is applied to the two shaping plates 1 through the support frame, so as to avoid the increase of the concave depth of the water baffle 3 and the tendency of the two shaping plates 1 to shrink.

[0032] In this embodiment, refer to Figure 3 A cover plate 10 is provided on the top of the rear pressure plate 9, and the cover plate 10 is located on the top of the shaping frame. One end of the cover plate 10 is placed on the top of one of the shaping plates 1, and the other end of the cover plate 10 is placed on the top of the other shaping plate 1. The cover plate 10 facilitates quick positioning of the rear pressure plate 9.

[0033] In this embodiment, the support arm 8 can be telescopic, and the telescopic method can be a traditional screw barrel method, thereby enhancing the flexibility of the support frame to adapt to different distances between the water retaining plate 3 and the shaping frame.

[0034] Reference Figure 1-3The anti-push frame is composed of a pair of vertical anti-push plates 4. The ends of the two anti-push plates 4 that are close to each other are hinged, and the ends of the two anti-push plates 4 that are away from each other are inclined at the same angle toward the direction of tunnel water flow and fit tightly with the corresponding tunnel side walls. The ends of the two shaping plates 1 that are away from each other are fixed to the tunnel ground by ground nails 5 to limit the displacement of the anti-push frame toward the direction of tunnel water flow. The hinge of the shaping frame and the hinge of the anti-push frame are connected as a whole through a hinge plate 6. The pressure exerted on the water retaining plate 3 will be transmitted to the anti-push frame through the shaping frame, and the anti-push frame is restricted by the ground nails 5 from sliding in the direction of tunnel extension. Therefore, when the anti-push frame is under pressure, the pressure will be transmitted to the side walls on both sides of the tunnel, so as to use the tunnel side walls to assist in supporting the anti-push frame, while at the same time it can also reduce the impact on the ground nails 5, highlighting its extremely strong stability.

[0035] In this embodiment, refer to Figure 1 and Figure 5 A pair of vertical holes 11 are provided inside the hinge plate 6, and the two vertical holes 11 are respectively used for the hinge shafts of the shaping frame and the anti-push frame to pass through.

[0036] In this embodiment, refer to Figure 2 and Figure 3 The ends of the two anti-thrust plates 4 that are away from each other are both provided with sleeve holes 12 for the ground nails 5 to be inserted. The formation of the sleeve holes 12 can be directly welded to the ends of the anti-thrust plates 4 with steel pipes that are flush with them above and below.

[0037] During actual use, the water baffle 3 should be placed in front of the shaping frame first, and then the front of the water baffle 3 will be concave into an arc shape as the two shaping plates 1 of the shaping frame swing. After that, the entire device can be placed horizontally in the tunnel, and ensure that the water baffle 3 faces the direction of the water gushing from the tunnel. It should be understood that whether it is a shaping frame or an anti-thrust frame, its overall length must be greater than the width of the tunnel. If it is less than or equal to the width of the tunnel, the true effect of the device cannot be achieved.

[0038] The blocking device provided in this embodiment has extremely strong anti-slip ability, can withstand tunnel water gushing with strong impact, ensure the integrity of the rock and soil around the tunnel, and ensure the safety of on-site rescue and drainage environment.

[0039] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
