Description

Viaduct water collection and drainage system

technical field

The utility model relates to a viaduct system, in particular to a viaduct water collection and drainage system.

Background technique

At present, there is a problem of poor drainage in urban viaducts, which will cause water accumulation on the bridge surface, which will be directly discharged under the bridge, causing water accumulation and other problems under the bridge. The travel of urban residents brings many troubles, and these problems are also a hot spot and difficulty in urban municipal drainage.

In real life, when rainwater falls on the bridge deck, it will be discharged directly from the drain outlet to the bridge deck along the bridge deck with vertical and horizontal slopes; or it will be drained to the bridge deck through sewer pipes without rainwater treatment and collection. On the one hand, it leads to the waste of rainwater, on the other hand, it is easy to flow directly into the green belt along the water pipe. However, the green belt is not designed with drainage facilities, and the entire green belt becomes a "reservoir" with serious water accumulation.

Utility model content

Aiming at the defects of the above-mentioned technologies at present, the utility model provides a viaduct water collection and drainage system capable of dealing with the problem of viaduct water accumulation and recycling water resources.

The technical scheme adopted by the utility model is a viaduct water collection and drainage system, which includes a water collection device arranged in the viaduct and a drainage device arranged in the viaduct or/and outside the viaduct. An intercepting device and a rectifying diversion device for intercepting impurities, and the drainage device includes a drainage pipeline and a reservoir connected to the drainage pipeline.

By installing water collecting devices and drainage devices on the viaduct, the rainwater on the viaduct is collected, and a storage tank is set up for recycling, which effectively solves the problem of water accumulation caused by the rainwater on the viaduct being directly discharged to the bottom of the bridge and saves water. resource.

Further, the intercepting device includes a rainwater grate arranged on the road surface of the viaduct, the rectification and deflector includes a deflector, and the water collection device also includes a rainwater bucket arranged under the rainwater grate, and the flow guide The plate is arranged on the lower surface of the rainwater grate or on the rainwater bucket, and the rainwater bucket is connected with the drainage pipeline.

The rainwater grate here is mainly to intercept the large-sized debris in the rainwater and filter the rainwater for the first time. When the rainwater passes through the rainwater grate, it begins to enter the rainwater bucket. In the process of entering the rainwater bucket, the rainwater will be guided The diversion and rectification function of the deflector prevents the formation of vortices, so that the rainwater on the bridge surface enters the rainwater bucket smoothly and smoothly, and can reduce the amount of air in the rainwater. At the same time, the deflector also plays a certain role in preventing impurities in the rainwater. Intercepting effect.

Further, the intercepting device also includes a filter screen arranged in the rainwater bucket.

After the rainwater is filtered by the rainwater grate (or after the rainwater grate and the deflector intercept the impurities in the rainwater), the rainwater will be filtered by the filter again to intercept the smaller-sized impurities.

Further, the intercepting device also includes a filter screen arranged in the drainage pipeline.

The filter screen can also be set in the drainage pipeline. Generally, the filter screen can be set in a place that is easy to remove, such as near the ground or near the bridge deck.

Further, a grit chamber is arranged around the rain bucket.

The grit chamber here is mainly used to precipitate impurities for later cleaning.

Further, the drainage pipeline is fixed on the bridge pier of the viaduct through a locking member.

Further, the locking member includes a detour structure adapted to the diameter of the drainage pipeline and bolts for fixing the detour structure on the bridge pier of the viaduct.

Further, the said locking piece is a metal locking piece.

Further, the water storage pool is arranged below the ground and connected with water facilities.

The beneficial effects of the utility model are:

By setting water collecting devices and drainage devices on the viaduct, the rainwater on the viaduct is collected, and a storage tank is set for recycling. It effectively solves the problem of water accumulation caused by the direct discharge of rainwater on the viaduct to the bottom of the bridge and saves water resources.

detailed description

The following embodiments will be described in conjunction with the accompanying drawings to illustrate the utility model in detail.

As shown in Fig. 1-4, the water collection and drainage system of the viaduct includes a viaduct pier 1, and the system also includes a water collecting device 2 arranged in the viaduct and a drainage device arranged outside the viaduct, and the described water collecting device 2 includes an intercepting device, The deflector 2021 for diverting and rectifying the rainwater and the rainwater bucket 202 for collecting the rainwater. The intercepting device includes a rainwater grate 201 and a filter screen 3 for intercepting impurities in the rainwater. The rainwater bucket 202 is arranged on the rainwater grate 201 Below, the deflector 2021 is arranged on the rainwater bucket 202 (the deflector here adopts 12 deflectors), and the drainage device includes the drainage pipeline 4 arranged along the pier 1 and the drainage pipeline 4 Connected reservoir 5, the reservoir 5 is arranged underground and connected with the water installation, where the water facility can be a waterworks, and rainwater is sent to the waterworks for recycling. The rainwater grate 201 intercepts the impurities in the water flow for the first time, mainly to prevent the coarse impurities in the water flow, isolate the coarse impurities in the periphery of the water collection device 2, and regularly clean up the debris around it to ensure the concentration of the bridge deck. The water device 2 is not blocked by impurities.

The rainwater grate 201 is arranged on the bridge deck 6 of the viaduct, close to both sides of the viaduct, because generally the viaduct has vertical and horizontal slopes, and the rainwater will flow to both sides, and the rainwater bucket 202 is connected with the drainage pipeline 4. The filter screen 3 is arranged in the drainage pipeline 4, close to the ground, so as to facilitate the removal and cleaning of the filter screen 3. A grit chamber 7 is arranged around the rainwater bucket 202 to deposit impurities for later cleaning.

The drainage pipeline 4 is fixed on the bridge pier of the viaduct through a metal lock 8. Generally, an iron lock can be used to extend the pier 1 downward. The metal lock 8 includes a detour adapted to the diameter of the drainage pipeline 4. A piece 801, the detour piece 801 fixes the drainage pipeline on the viaduct pier 1 through bolts 802.
