The utility model relates to a waterproof flow guide blind ditch structure at the connecting place of diaphragm wall, it includes flow guide blind ditch main part, flow guide blind ditch main part sets up at the connecting place of diaphragm wall, is used for guiding the ground water flow, prevents the ground water and accumulates at the connecting place, the utility model discloses a flow guide blind ditch is established, effectively guides the ground water flow, prevents the ground water and accumulates at the connecting place, reduces the seepage risk, improves the overall waterproof performance of diaphragm wall, guarantees the engineering quality. The application still has the advantages such as convenient construction, low cost, can satisfy the efficient and economic demand of modern underground engineering construction.

This utility model discloses an integrated low-flow-resistance pipeline valve assembly system for equipment outlets, including a support frame, a main pipe, a connecting pipe, an outlet pipe, valve assemblies, and instrument assemblies. The main pipe is fixed on the support frame; the first end of the connecting pipe connects to the inner cavity of the main pipe; the angle between the axis of the connecting pipe and the axis of the main pipe is 40-60°; the first end of the outlet pipe is fixed to the second end of the connecting pipe; the second end of the outlet pipe connects to the equipment; the valve assembly includes multiple low-flow-resistance valves and is fixed on the connecting pipe; the instrument assemblies are fixed on the connecting pipe or the outlet pipe. This utility model adopts a prefabrication assembly method, avoiding the cumbersome on-site pipeline connection, and making construction efficient and quick; by replacing the traditional right-angle elbow with a connecting pipe, water flow resistance can be reduced, fluid dynamics performance can be optimized, and kinetic energy loss during fluid turning can be reduced, thereby reducing water resistance and lowering the energy consumption of the equipment.
