Further, the top surface of the prefabricated water drain hole water drain pipe is provided with a gradient which is not less than 2%.
Further, the slope of the bottom surface of the drain pipe with the prefabricated drain holes is consistent with that of the bottom surface of the main beam flange plate.
The invention has the beneficial effects that:
the prefabricated water drain pipe with the water drain hole is effectively connected with the flange plate of the main beam through the connecting piece, so that gaps between the water drain hole and the main beam caused by various factors during the operation of the bridge are avoided, and accumulated water on the surface of the bridge is prevented from being discharged along the outer contour of the water drain hole; the prefabricated water drain hole water drain pipe is provided with water dropping rocks, and when water leaks between the prefabricated water drain hole water drain pipe and the water drain pipe, the water dropping edges can block the water from flowing to bridge wing plates and web plates; the prefabricated water drain hole drain pipe is provided with a drain pipe fixing device, and can be effectively connected with the existing drainage facility for a bridge provided with centralized drainage; in conclusion, the prefabricated water drain pipe with the water dropping edge can fundamentally solve the problems of water seepage, saltpetering and the like of the main beam concrete caused by water leakage of the bridge water drain hole, and the integrated structure of the water drain pipe with the water dropping edge is convenient for construction. The prefabricated water drain pipe with the water dropping edge can be widely applied to various concrete bridge structures and steel structure bridges.
The prefabricated outlet water-drain pipe adopts the ultra-high performance concrete, make full use of its super high tensile strength, shock resistance and good impermeability, advantages such as durability, prefabricated outlet water-drain pipe can effectively avoid because the girder disease that leaks and lead to in outlet department, improve the bridge durability, and the structure of outlet water-drain pipe integration is convenient for be under construction, the installation of prefabricated outlet water-drain pipe goes on simultaneously with bridge major structure construction, the on-the-spot location installation that only needs, compare with the original design of bridge, do not increase the engineering volume basically, construction progress has been accelerated.
