Embodiment Construction

[0025] like Figure 1 to Figure 7 As shown, the bridge drainage device of embodiment 1 includes the drain pipe 2 arranged in the reserved hole on the concrete beam 6 of the bridge and the nozzle seat 1 pressed on the top surface of the drain pipe 2, the bridge of the bridge The surface waterproof layer 3 extends to within the outer edge of the mouth of the drain pipe 2, the bottom edge of the mouth seat 1 is pressed on the bridge deck waterproof layer 3, and the bridge within the outer edge of the mouth of the drain pipe is lapped. The surface waterproof layer and the drain pipe are independent parts, and there is a spout seat on the waterproof layer. Even frequent vibrations caused by vehicles passing by will not cause the problem of cracking of the waterproof layer and the drain pipe, and the water between the layers cannot Penetrating the waterproof layer can only flow into the drain pipe along the waterproof layer, so that the purpose of no water leakage around the drain p...

Abstract

The invention relates to a bridge drain system which comprises a drain pipe (2) arranged in a foreseen hole of the bridge and a pipe outlet seat (1) pressed on the top surface of the drain pipe (2); abridge deck water barrier (3) of the bridge extends within the outer margin of the pipe outlet of the drain pipe (2). The bridge drain system can exclude interlayer water between asphalt concrete anda water barrier of a bridge and avoid dripping water and water leakage of the periphery of the drain pipe (2).

Description

technical field [0001] The invention relates to an accessory facility in the field of bridges, in particular to a bridge drainage device. Background technique [0002] The structure of existing bridges generally includes concrete beams and asphalt concrete decks arranged on top of the concrete beams. Due to the gaps in the asphalt concrete bridge decks, water on the bridge deck will permeate through the asphalt concrete decks, causing erosion and damage to the concrete beams below. Damage to the bridge constitutes a safety hazard. In order to prevent the complex seepage water from damaging the concrete beam, a waterproof layer is generally installed between the concrete beam and the asphalt concrete bridge deck, and the bridge deck near the bridge guardrail or curb is lower. When it rains, most of the water on the bridge surface is discharged into the drain pipe, and a small part penetrates into the waterproof layer of the asphalt concrete bridge deck through the asphalt gap...
