Description

A drainage device for road and bridge construction

Technical field

The utility model relates to the technical field of road and bridge construction, and in particular to a drainage device for road and bridge construction.

Background technique

Roads and bridges tend to accumulate water during heavy rains. Long-term accumulation of water on the road and bridge deck will not only affect the service life of the asphalt layer on the bridge deck, but also cause a water film, which greatly reduces the anti-skid ability of the bridge deck and prevents high-speed vehicles from braking normally. It is prone to sideslip. At the same time, the high-speed driving of vehicles will splash water on the bridge, affecting the driver's vision and leading to driving accidents in rainy days. Therefore, a drainage device is required to drain water from the road and bridge deck in heavy rain. However, the existing There are some problems when using the drainage device:

1. The drainage efficiency is not high and it is easy to get clogged. When the existing drainage device is in use, a sudden heavy rain will bring a large amount of leaves and other impurities mixed with it. When they are concentrated at the drainage device, the leaves and other impurities will block the water inlet at the top of the drainage device. , resulting in a significant reduction in drainage efficiency;

2. Internal cleaning is cumbersome. During the drainage process of existing drainage devices, the water body will be mixed with many impurities, and a large amount of impurities will accumulate inside the drainage device after passing through the interior of the drainage device, which requires regular cleaning. Most of the existing cleaning methods Manual cleaning is used for processing, resulting in cumbersome cleaning.

For this reason, Chinese patent (Application No. 202020402846.9) discloses "a new type of road and bridge drainage device". This device has a height difference between the water baffle and the drainage bucket, and the surface of the drainage bucket is arranged in an arc shape. At the same time, one side of the water baffle The side is arranged in an arc shape, so that the water flow will impact downward when draining, thereby impacting the impurities on the drain bucket, effectively reducing the clogging of the water inlet hole, ensuring the normal discharge of the water flow, and at the same time, no need for primary drainage. Manual cleaning is done multiple times, reducing the labor burden. However, when impurities accumulate on the side walls of the arc-shaped housing, they still cannot be cleaned out in time, which will still block the water inlet of the side wall, affect the water drainage efficiency, and water accumulation will still occur.
