The invention relates to a high pressure-resistant leak stoppage agent and leak stoppage slurry containing the same. The high pressure-resistant leak stoppage agent consists of the following components in percentage by mass: 25.0 to 27.0 percent of soybean particles, 31.0 to 32.0 percent of walnut shell flour, 7.1 to 7.5 percent of vermiculite, 2.1 to 2.5 percent of peanut hull meal, 22.0 to 22.5 percent of cement and 10.0 to 11.0 percent of flocculation coating agent LHB-105 for drilling fluid. The leak stoppage slurry consists of base slurry and the high pressure-resistant leak stoppage agent, wherein 3 to 9 grams of high pressure-resistant leak stoppage agent is added into every 100 milliliters of base slurry. The leak stoppage agent and the leak stoppage slurry stop leaking by combining chemical leak stoppage with particle bridging leak stoppage, so that the technical problems of aperture leak, crack leak and fracture leak under a well can be solved. The leak stoppage agent and the leak stoppage slurry are suitable for severe well leakage caused by a pore formation, a crack formation, a long-section broken formation and the like and can be applied to leak layer construction of which the leak position is difficultly determined.

The invention discloses a life-cycle treatment method of water inrush in a tunnel. The method comprises the steps that three-dimensional morphologic features of a water conductive structure of a water inrush zone in the tunnel are obtained by combining geological data, excavation data, detection results of comprehensive geophysical detection and numerical calculation results; grouting sealing water inrush is taken into account, surrounding rock physical mechanical parameters are improved simultaneously, design of a treatment scheme is conducted on the water inrush zone in the tunnel, and design of a keyhole and a drainage keyhole is conducted according to a water inrush main controlling structure; the stability of the tunnel in the construction period and the safety in the operation period are guaranteed by conducting numerical simulation on the tunnel section which is reinforced according to the design scheme; grouting construction is conducted according to the design scheme, a monitoring device is buried during the construction process, and feedback optimal design is implemented; inspection is conducted on the treatment effect of the grouting reinforcement section in the tunnel, and the excavation time is determined. According to the life-cycle treatment method of the water inrush in the tunnel, it is guaranteed that the surrounding rock in the tunnel construction period is stale and water inrush of the tunnel does not occur in the operation period, the chronic problem that nine of the ten tunnels leak is completely eradicated, and the effective treatment of the water inrush in the tunnel and the environmental protection are achieved.

The invention provides a pipe opening plugging device which comprises a body, a blocking ring, a plugging rubber ring and a piston, wherein the body is in a cylindrical structure having the hollowing inside and one opened end; a penetrating hole is formed in the end part, opposite to the opened end, of the body; the piston, the plugging rubber ring and the blocking ring are arranged in the body in a sleeving manner in sequence; the piston comprises a piston head and a piston rod; the piston rod extends out of the penetrating hole; the piston head is positioned in the hollow cavity of the body; a clamping ring for limiting the blocking ring, the plugging rubber ring and the piston head in the hollow cavity of the body is fixedly clamped outside the blocking ring. The pipe opening plugging device is wide in application range, namely the pipe piece opening can extend into the hollow cavity; the tolerances of the end surfaces of the pipe piece opening are inconsistent; the plugging effect can not be influenced by uniformity, lacking or redundance, compacting in a transportation process or installation process, and the like; the service life is long, so that parts, such as the plugging rubber ring, are not required to be replaced frequently; the plugging effect is good, and the plugging rubber ring and the outer wall of the pipe piece opening are in flexible fastening, so that a sealing performance is good.

The invention discloses an underground communication pipe anti-rat cover comprising two pipe filling half bodies. Each pipe filling half body comprises a semicircular cover plate and an annular guide plate arranged at the lower end of the semicircular cover plate. The straight edge of each semicircular cover plate is provided with two symmetrical semicircular openings. The outer arc edge near each semicircular cover plate is provided with a filling through hole, a fixed duct is fixedly arranged at the lower end of the filling through hole, and the lower end of the fixed duct is fixedly connected with an elastic filling capsule. A clamping device is arranged on each pipe filling half body. When the two pipe filling half bodies are in butt joint, every two semicircular openings facing each other form a threading hole. The large threading holes formed through butt joint of the two pipe filling half bodies allow communication cables of different types to pass through. Meanwhile, gaps around a cable can be filled by filling an appropriate amount of filler in the elastic filling capsules, and dustproof and anti-rat effects are achieved.
