The utility model discloses a waterproof connector group and female seat waterproof connector thereof, the female seat waterproof connector contains a pipe body, a water valve subassembly and a waterproof washer, the inner ring wall of pipe body is inwards protruding a retraction, and the retraction is near the pipe orifice, the water valve subassembly sets up between the retraction and rear pipe orifice, and the waterproof washer is located between the pipe body and the movable valve piece of water valve subassembly, and sets up after the retraction of pipe body, so, even if the front end of male waterproof connector is inserted from the front pipe orifice of female seat waterproof connector when being inclined, cannot reach the waterproof washer, and when the male waterproof connector passes the retraction, has not inclined any longer, and the waterproof washer can be pressed and compactly attached the male waterproof connector evenly, thereby prolongs its service life, maintains the waterproof function of female seat waterproof connector.

A construction method for enhancing the joint waterstop effect of an underground diaphragm wall comprises the steps that after an underground diaphragm wall formwork is placed in a foundation pit, an underground diaphragm wall framework unit at the starting end, a plurality of underground diaphragm wall framework units at the middle sections and an underground diaphragm wall framework unit at the terminating end are sequentially placed in the formwork, and each underground diaphragm wall framework unit comprises a reinforcement cage and H-shaped steel at the end; a limiting inclined plate is arranged at the included angle position of the outer side face of the H-shaped steel, after the outer side face of the H-shaped steel in the previous underground diaphragm wall framework unit is cleaned, the next underground diaphragm wall framework unit continues to be placed, and after placing is completed, a grouting pipe and a water stop steel plate are vertically inserted into the included angle position in the limiting inclined plate; concrete grout is injected into the position of the reinforcement cage to form the underground diaphragm wall, before the underground diaphragm wall is condensed and hardened, cement grout is injected into the grouting pipe, the grout at the position of the replacement included angle is squeezed out, and the cleaning quality of the grout is improved.

The invention discloses a tunnel composite lining drainage system, and relates to the technical field of tunnel engineering, a waterproof and drainage layer is arranged between a primary support and a secondary lining, a first side ditch and a second side ditch are respectively arranged on two sides of the bottom of a tunnel, the second side ditch is communicated with a central drainage ditch through a transverse drainage pipe, and the inner layer of the waterproof and drainage layer is a woodworking cloth layer. Drainage plates are evenly laid below the woodworking cloth layer, waterproof plates are connected between the drainage plates in a lap joint mode, annular blind pipes are arranged in the middles of the drainage plates, longitudinal blind pipes are embedded into the bottoms of the drainage plates and the bottoms of the annular blind pipes, and the longitudinal blind pipes are communicated with the first side ditch; the secondary lining construction joint is provided with a middle-buried type water stop belt, and the positions, on the two sides of the middle-buried type water stop belt, of the construction joint are filled with water stop sealing materials. And the construction joints are filled with high-elasticity water stop sealing materials, the sealing performance is high, the failure probability of the water stop belt can be reduced, and the waterproof and drainage effects are improved.

This utility model discloses a folded plate structure and its installation structure for a through-wall component, including an upper folded plate and a lower folded plate for covering the surface of the outdoor portion of the through-wall component and preventing it from being eroded by rainwater. The upper folded plate includes an upper connecting plate fixed to the wall, an upper top plate fixedly connected to the bottom of the upper connecting plate for covering the top surface of the outdoor portion of the through-wall component, and an upper outer plate fixedly connected to the side of the upper top plate away from the upper connecting plate for covering the side surface of the outdoor portion of the through-wall component. The lower folded plate includes a lower connecting plate fixed to the wall and a lower bottom plate fixedly connected to the top of the lower connecting plate for covering the bottom surface of the outdoor portion of the through-wall component. The side of the upper folded plate away from the wall is located on the outer side of the side of the lower folded plate away from the wall. This utility model has excellent waterproof capability, effectively extends the life of the through-wall component, avoids the risk of water leakage, reduces construction difficulty, and has high promotional value.

The invention provides a wave-absorbing heating composite material, an asphalt composite coiled material and an asphalt coiled material laying method, the wave-absorbing heating composite material comprises a discharge material and a dielectric material, and the length-diameter ratio of the discharge material is greater than or equal to 5. According to the wave-absorbing heating composite material, the microwave heating efficiency of the asphalt coiled material can be improved, the requirement for the heating rate in the construction process that the asphalt coiled material is laid on the surface of a base layer such as a cement board is met, the asphalt coiled material is bonded to the base face, and the waterproof function of the asphalt coiled material is guaranteed.

The utility model discloses a lamp which comprises a lamp body, and a containing cavity with an opening is formed in the lamp body. A groove is formed in the surface of the elastic ring, and the cavity wall at the opening of the containing cavity is inserted into the groove; the light-transmitting cover is arranged on the surface, deviating from the groove, of the elastic ring; and the connecting assembly is used for locking or unlocking the light-transmitting cover on the lamp main body, so that the accommodating cavity is sealed or opened. The waterproof function of the lamp is guaranteed, and meanwhile maintenance of internal photoelectric elements is facilitated.
