AI Technical Summary
In heavy rainy weather, the existing drainage pipes for road and bridges increase the weight of the pipe body and the working pressure of the lifting ring. The thickness of the pipe wall is required to avoid breakage, but this increases the cost and is difficult to adapt to the needs of mass production.
A drainage pipe for road bridges is designed. By setting up a gasket ring, limit ring, expansion rod, stiffener rib, hanging parts, locking ring, pressure plate and other structures on the pipe body, the stress area of the pipe body is expanded, the thickness of the pipe body is reduced, and the cost is reduced.
By reducing the thickness of the pipe body, the overall cost of the drainage pipe is reduced, which can better adapt to the needs of mass production, and at the same time improve the stability and stress uniformity of the pipe body.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drain pipes, in particular to a drain pipe for road bridges. Background Technique
[0002] In order to ensure driving safety and smoothness and prevent the bridge deck structure from being eroded by precipitation and affecting the durability of the bridge, a perfect bridge drainage system should be set up according to relevant national specifications. When draining water from a bridge or elevated road, drain pipes are often laid on the bottom surface of the bridge or elevated road, and most of these drain pipes are fixed to the bottom of the bridge or elevated road through suspension rings.
[0003] In heavy rain weather, a large amount of flowing rainwater will fill the drain pipe, greatly increasing the weight of the drain pipe. This will not only increase the working pressure on the suspension ring, but also the force of the suspension ring on the drain pipe poses certain requirements for the strength of the drain pipe, resulting in the need for a certain thickness of the pipe wall of the drain pipe to avoid being pulled off. However, this type of drainage pipe is installed at the bottom of the bridge and is rarely affected by external factors. But only for this reason, thickening the drain pipe has a poor economic effect and is difficult to meet the needs of mass production. Therefore, a drain pipe for road bridges is proposed for improvement. Content of the Utility Model
