The bridge drainage facility is used as an auxiliary structure of the bridge, and plays an important role in the durability and the driving experience of the bridge. The existing bridge drainage design is that bridge deck longitudinal and transverse slopes are adopted to collect bridge deck rainwater to enter a water collecting well, and then the rainwater is drained to ground drainage facilities or rivers through a downpipe.

But bridge designers often neglect the problem of ponding collection and drainage of the under-bridge side roads. When the condition of the pavement of the auxiliary road is special or the rainfall is too large, rainwater can not be prevented from falling onto the auxiliary road under the bridge, and cannot be effectively drained into a drainage device.

For example, when the ground auxiliary channels on two sides below the bridge are bidirectional large longitudinal slopes, rainwater directly falls onto the auxiliary channels due to overlarge rainwater amount, and when the drainage device does not reach the water drainage time, accumulated water on the bridge also falls onto the auxiliary channels through the downpipes. The large longitudinal slope auxiliary road surface longitudinal slope is big, and the auxiliary road both ends are high middle low, if there is a large amount of ponding on the auxiliary road, ponding can be in the lowest slope bottom of auxiliary road middle department long-term deposit can't the drainage to among the drainage device, and the washing away that receives water for a long time can make the road infiltration. If the temperature is low, the surface water is frozen, and the durability and the usability of the road are greatly influenced. However, if the auxiliary channel is separately provided with the drainage device, the two drainage paths can mutually influence in the collection and drainage processes.

Meanwhile, the flood control box culvert is built at the slope bottom, and the connecting device of the drainage device does not need to be built with time. When the auxiliary road 4 is constructed, a certain slope is set, so that accumulated water on the auxiliary road is drained to the rainwater side ditch 5.

On the other hand, the utility model provides a bridge drainage system with auxiliary road, it can use above-mentioned mounting method to install, include: a water collecting tank 2, a rainwater connecting pipe 3, a rainwater side ditch 5 and a drainage device 11.

The following is a detailed description of a specific embodiment.

Referring to fig. 2, 3 and 5, the auxiliary road 4 is a bidirectional longitudinal slope road, and the whole of the road is high at two ends and low in the middle in the longitudinal direction. And the drainage system includes: a water collecting tank 2, a rainwater connecting pipe 3, a rainwater side ditch 5 and a drainage device 11.

Wherein the water receiving tank 2 is arranged on the side surface of the lower part of the pier bottom ground of the pier. The downpipe installed along the bridge pier body is communicated with the water collecting groove 2 on the bridge, and the water collecting groove 2 at the bottom of the bridge is collected by the accumulated water on the bridge. The water collecting tanks are arranged in a plurality of numbers, and a plurality of water collecting tanks 2 are arranged at the bottom of each pier position and are of a reinforced concrete structure. The rainwater connecting pipe 3 adopts a phi 300 reinforced concrete socket pipe. The rainwater side ditch 5 adopts a reinforced concrete cast-in-place structure, the top plate adopts a prefabricated reinforced concrete cover plate 6, and a plurality of slender small holes are formed in the cover plate 6 and are used for accumulated water to flow in. The rainwater side ditch 5 is arranged on the outer side of the under-bridge auxiliary channel 4. Drainage device 11 sets up in the lower of the two-way longitudinal slope of auxiliary road 4 for adopting the flood control box culvert of dark culvert structure construction, transversely wears the auxiliary road 4 of bridge both sides down, and at 11 open-tops of drainage device simultaneously, the rivers that make rainwater gutter 5 collect are discharged from the opening part.

The drainage means 11 shown in fig. 2 is arranged to pass through the secondary channel obliquely because the bottom of the secondary channel has an existing culvert in the embodiment, and the technicians can easily construct the flood control culvert by means of the culvert. In this scheme, however, the flood control box culvert can obliquely pass through the lower part of the auxiliary channel and can be constructed in other directions, and only the lower part of the auxiliary channel needs to be communicated with the rainwater side ditch. The direction of the culvert does not influence the drainage of accumulated water.

Referring to fig. 3, the construction sub-track 4 may be continued to form a first layer of asphalt 9 and a second layer of asphalt 10.

To sum up, the utility model provides a drainage system has solved the problem of the easy ponding of the auxiliary road under the bridge, especially has the auxiliary road condition of certain slope to auxiliary road 4, builds the box culvert and can more efficient discharge the accumulational ponding at the bottom of the slope. The rainwater side ditch 5 collects the accumulated water from the auxiliary road continuously, so that the accumulated water is prevented from being accumulated on the auxiliary road. The water collecting tank 2 and the rainwater connecting pipe 3 are both buried on the ground and are buried under the road surface without influencing the normal work of the road surface of the auxiliary road 4. Accumulated water on the auxiliary channel and collected water on the bridge are drained to the rainwater side ditch 5 communicated with the box culvert through different paths, the length of the rainwater side ditch 5 is extended along with the auxiliary channel, the whole longer accumulated water containing capacity is larger, the rainwater side ditch can be discharged through the top cover hole even if the rainwater side ditch is filled with water, the rainwater side ditch 5 is refilled with the discharged water when the precipitation is smaller, and the accumulated water on the auxiliary channel cannot be accumulated for a long time. Therefore, the accumulated water discharge on the bridge and the accumulated water discharge on the auxiliary road have less mutual influence.
