Embodiment 1

[0047] In a typical embodiment of the present invention, refer to figure 1As shown, a reinforcement device for grouting treatment of leakage water in operational tunnels, including a base 7, a moving mechanism that can move relative to the base 7 is provided under the base 7, and a telescopic support leg 8 is also provided under the base, A base support bracket is provided above the base 7, and a grouting mechanism is arranged inside the bracket 1, and the grouting mechanism is connected with the slurry delivery pipe 14, and each side of the support 1 is provided with an opening 16 for the slurry delivery tube 14 to pass through, and the support 1 A plurality of telescopic mechanisms 5 are arranged on the side of the tunnel, and each telescopic mechanism 5 is movably connected with the corresponding support plate 2 so that the support plate 2 can fit the inner wall of the tunnel. The support plate 2 has a grouting hole 4 for the grout delivery pipe 14 and the tunnel. The secon...

Embodiment 2

[0067] This embodiment provides a working method for a reinforcement device for grouting treatment of leakage water in an operating tunnel, which specifically includes the following steps:

[0068] A reinforcement device for grouting treatment of seepage water in operating tunnels is pushed into the tunnel that needs grouting through casters 9;

[0069] Start the switch of the telescopic mechanism 5, so that the electric dowel rod drives the support plate 2 to move, stretch the support plate 2 until the support plate 2 contacts the inner wall of the tunnel, and then close the switch of the telescopic mechanism 5;

[0070] Start the switch of the caster 9, retract the moving mechanism relative to the base 7, so that the caster 9 shrinks to the inside of the base 7, until the caster 9 is retracted to the inside of the base 7, at this time, when the support plate 2 supports the inner wall of the tunnel, the reinforcement device is suspended;

[0071] Place the support base 10 und...

Abstract

The invention discloses a reinforcing device for grouting treatment of leakage water of an operating tunnel and a working method, solves the problems that a ballast bed in the tunnel and the inner wall of the tunnel are bulged, low in pressure resistance and easy to damage in the prior art, and has the beneficial effects that the stability of the ballast bed and the inner wall of the tunnel during grouting is ensured, the grouting pressure is prevented from being too large, and the service life is prolonged. The reinforcing device has the beneficial effects that the problem that a track bed and the inner wall of a tunnel bulge due to tunnel grouting is solved, and according to the specific scheme, the reinforcing device comprises a base, the base is provided with a moving mechanism, the moving mechanism is movably arranged relative to the base, and the base is provided with telescopic supporting legs; a plurality of telescopic mechanisms are arranged on the side portion of the base supporting support and movably connected with the corresponding supporting plates, the supporting plates are matched with the interior of a tunnel in shape, a grouting mechanism is arranged on the inner side of the support and connected with a slurry conveying pipe, and the support is provided with an open hole for the slurry conveying pipe to penetrate through. And a grouting hole is formed in the supporting plate so that the slurry conveying pipe can be connected with a tunnel lining preset grouting pipe.

Description

technical field [0001] The invention relates to the technical field of tunnel treatment and reinforcement, in particular to a reinforcement device and a working method for grouting treatment of seepage water in operating tunnels. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Tunnels are engineering buildings buried in the ground, which are divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, military tunnels, etc. In recent years, domestic subway tunnels have developed rapidly. Due to the different construction times of tunnels, the design of tunnels Different standards and construction technology levels, coupled with differences in geological conditions along the subway, most tunnels have problems such as cracks, lining cracks, and voids to varying degrees, resulting in a large amount of water leakage in the...
