Bridge floor water drain pipe device for bridge and construction method

Abstract

The invention provides a bridge floor water drain pipe device for a bridge and a construction method. According to the bridge floor water drain pipe device for the bridge, a bridge floor is composed of a waterproof layer I, a lower layer asphalt concrete layer and a surface asphalt concrete layer, the bridge floor water drain pipe device for the bridge includes a water drain pipe preformed hole, awater drain pipe and a water drain pipe tray, wherein the water drain pipe preformed hole penetrates through the bridge, the water drain pipe is arranged in the water drain pipe preformed hole, and agrouting space is reserved between the water drain pipe preformed hole and the water drain pipe; and the water drain pipe tray is mounted outside the water drain pipe, and the water drain pipe tray is attached to the bottom of the bridge. According to the bridge floor water drain pipe device for the bridge, ponding can be drained, the good waterproof effect is provided, and the service life of the surface asphalt concrete layer is prolonged.

Description

technical field [0001] The invention relates to the technical field of bridge waterproofing, in particular to a bridge deck drainage pipe device and a construction method for bridges. Background technique [0002] The drainpipe is an important facility for the drainage of the bridge deck. When the conventional drainpipe is installed, the gap between the drainpipe and the reserved hole of the bridge cannot be effectively controlled, and the gap between the drainpipe and the reserved hole of the bridge cannot be filled or filled. Phenomena such as uneven compaction make the water accumulated between the bridge deck or the bridge deck asphalt pavement layer seep downward along the manhole cover during the operation of the bridge, and finally flow down through the reserved hole wall of the drain pipe, polluting the appearance quality of the bridge . Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a...
