The utility model discloses an existing tunnel lining leakage water drainage structure, relates to the field of tunnel lining structures, and aims to solve the problem of poor tunnel stability after existing tunnel lining leakage water disease treatment, in a region with serious leakage water, a secondary lining is chiseled away to form a stepped groove, a first groove accommodates a water diversion pipe to collect leakage water, and a second groove accommodates a water diversion pipe to collect leakage water. And a reinforcing mesh is laid in the second groove and connected with anchor rods implanted into the surrounding rock to form a reinforcing structure, so that the strength of the tunnel after the secondary lining is chiseled away is guaranteed, and the stability and safety of the tunnel after water leakage damage treatment are guaranteed.

The utility model discloses a color steel tile clamping structure, which comprises a color steel tile, purlins and a clamping piece, the clamping piece comprises two L-shaped mounting seats and a clamping head integrally connected between the upper ends of the two L-shaped mounting seats, the two L-shaped mounting seats are respectively, correspondingly and fixedly mounted on the two corresponding purlins, and the two purlins are respectively and fixedly mounted on the two L-shaped mounting seats. The clamping head is of a trapezoidal structure matched with a tile ridge of the color steel tile, and the clamping head is clamped on the lower side of the tile ridge. On the basis that the color steel tiles do not need to be punched and fasteners do not need to be assembled, rapid installation and reliable fixation of the color steel tiles can be achieved, the installation steps are simplified, and the installation efficiency is improved; besides, the color steel tile does not need to be punched, so that the waterproof performance of the color steel tile is ensured, the possibility of rainwater leakage is reduced, and the color steel tile is convenient to renovate and replace.

The application provides a downhole grouting method for plugging a water-conducting space of laterally burned rock, comprising the following steps: determining a water-conducting space of laterally burned rock of a coal seam and a working face to be mined in the coal seam affected by the water-conducting space, and drawing a curtain line of the water-conducting space outside a mining disturbance damage range of the working face to be mined; arranging a plurality of first grouting holes between the curtain line and the burned rock, grouting the first grouting holes, and determining diffusion ranges of slurries with different concentrations; determining a slurry concentration corresponding to a second grouting hole and a diffusion range of a slurry corresponding to the slurry concentration, determining a spacing of the second grouting hole according to the diffusion range of the slurry corresponding to the slurry concentration; arranging a plurality of second grouting holes between the curtain line and the burned rock according to the spacing of the second grouting hole, and grouting the second grouting holes from the working face to be mined according to the slurry concentration corresponding to the second grouting hole. The application improves the accuracy of grouting plugging, reduces the grouting time, saves the amount of grouting slurry, and reduces the grouting cost.

The utility model discloses a breathable waterproof male erection assisting device which comprises an erection assisting device body, a sealing valve and an air inlet mechanism, the sealing valve is arranged on the erection assisting device body, the sealing valve comprises a valve body and a waterproof breathable film, the valve body is arranged on the erection assisting device body in an airtight mode, the waterproof breathable film is arranged on the valve body, and the air inlet mechanism is arranged on the valve body. The sealing valve is arranged on the valve body, the waterproof breathable film is arranged on the sealing valve, so that the waterproof breathable film prevents liquid in the erection assisting device body from flowing into the valve body, the air inlet mechanism is arranged on the sealing valve, and external air is injected into the valve body through the air inlet mechanism, so that the liquid in the erection assisting device body generates bubbles under the action of the air. According to the utility model, soft treatment is carried out by utilizing bubble hydrodynamic massage, so that the treatment effect is enhanced, and sensitive parts cannot be damaged.

The utility model discloses a solar module frame locking structure, including solar frame, pressing plate spare, U type card spare and bolt, its characterized in that: through pressing plate spare and U type card spare to the adjacent solar frame form the upper and lower compression, and utilize bolt and lock, pressing plate spare, including arched cover, arched cover is located the junction line just above of both sides solar frame, the both sides fixed of arched cover are pressed together section abutting on the upper portion of corresponding solar frame, and the screw is gradually tightened after screwing into the inside of the abdominal rib plate, so that arched cover forms certain lower pressure tight, so that the compression section and sealing strip of both sides are closely attached in solar frame top surface, and form effective sealing to solar frame top edge under the cooperation of waterproof convex rib, and such design not only guarantees the connection firmness and water -resistant effect of adjacent frame, can prevent the adjacent frame from displacement and vibration and cause sealing element to loosen the seam simultaneously.
