Specific embodiment

The utility model is further described below in conjunction with attached drawing:

The present embodiment provides a kind of bridge drainage structures, as Figure 1-Figure 4, including collection water assembly 300, screen assemblies 100 and top cover 200.

Collecting water assembly 300 includes shell 310, drip pan 320 and the drain interface 330 for connecting drainpipe.Shell 310 be cylindrical body, and internal is cavity.It is provided with first through hole 311 at the top of 310 cavity of shell, at the bottom of 310 cavity of shell Portion is provided with the second through-hole 312.First through hole 311 and the second through-hole 312 are oppositely arranged, and are set on the hole wall of the second through-hole 312 It is equipped with screw thread 112.Drip pan 320 is cylindrical in shape, and in order to facilitate rainwater-collecting, drip pan 320 is funnel-shaped.Drip pan 320 it is big Diameter end is set up, and is fixedly connected on shell 310, so that first through hole 311 is connected to drip pan 320；The path of drip pan 320 Hold inside that is down-set, and extending to shell 310.Drain interface 330 is set to shell 310 and is connected to the sky of shell 310 Bottom of chamber portion.

Screen assemblies 100 include pedestal 110 and sieve 120.Sieve 120 is cylindrical in shape, if 120 surface of sieve is provided with dry screen Hole 121.120 lower end of sieve is fixedly connected on 110 top of pedestal.The top of 110 side of pedestal is provided with screw thread 112, the screw thread 112 match with the screw thread 112 of the second through-hole 312, so that pedestal 110 is connect with 310 screw thread 112 of shell；110 side of pedestal Lower part is convexly equipped with anti-skid bulge 111, turns pedestal 110 when facilitating disassembly pedestal 110.Pedestal 110 and 310 screw thread 112 of shell Connection is so that screen assemblies 100 are fixedly connected on shell 310, and 320 lower end of drip pan is made to be placed in 120 upper end of sieve.In order to Guarantee flow into drip pan 320 rainwater can fully flow into sieve 120, the miner diameter end of drip pan 320 be provided with vertically to The extension 321 of lower extension, so that 320 lower end of drip pan is more placed in 120 upper end of sieve.Meanwhile rain in order to prevent Water seeped the connecting sewing of pedestal 110 and shell 310 and water leakage situation occurred, was arranged in pedestal 110 and 310 junction of shell There is sealing ring 400.

The bridge drainage structure of the utility model is used for bridge drainage system.When bridge 500 is constructed, by the utility model The shell 310 of bridge drainage structure pours or is embedded in bridge 500, and the bridge drainage structure of the utility model is made to be fixed on bridge In 500 structures, and first through hole 311 is made to be connected to bridge roof 510, i.e. connection bridge floor.Then drainage pipeline is made to be connected to draining Interface tube 330.In general, the top surface of shell 310 is lower than bridge floor, and bridge floor is provided with 200 mounting groove of top cover.Top cover 200 is in Tabular, top cover 200 are provided with the permeable hole 210 between the two sides of several connection plate-shaped lid parts 200, rainwater are passed through Top cover 200.200 activity of top cover is embedded in 200 mounting groove of top cover and is carried on bridge 500.Top cover 200 is embedded at top cover 200 After in mounting groove, top cover 200 covers first through hole 311.After the bridge drainage structure of the utility model is installed on bridge 500, The anti-skid bulge 111 of pedestal 110 protrudes from the bridge bottom wall 520 i.e. bottom surface of bridge 500, facilitates the disassembly of screen assemblies 100.

In use, the rainwater of bridge floor is flowed into again by removing impurity by 200 primary filtration of top cover after the confluence of transverse and longitudinal slope Drip pan 320；Drip pan 320 will flow into its internal rainwater catchment to sieve 120, and sieve 120 filters in rainwater again Impurity simultaneously flows into rainwater in the cavity of shell 310；Rainwater in the cavity of shell 310 is discharged by drainage pipeline again.For a long time After use, the impurity stockpiled in sieve 120 is more and more.At this point, pedestal 110 can be turned and remove sieve 120 and cleaning screen The impurity stockpiled in net 120.In order to avoid long-term ponding in screen assemblies 100, the roof of pedestal 110 is higher than 310 bottom of shell Inner wall, the rainwater for flowing into screen assemblies 100 can be discharged completely, avoid and stockpile when removing screen assemblies 100 Rainwater brings inconvenience.

The advantages of bridge drainage structure of the utility model is: top cover 200 covers first through hole 311, when rainwater passes through Impurity when top cover 200, in 200 primary filtration rainwater of top cover；The rainwater for flowing into drip pan 320 is mingled with impurity and then flows into sieve Screen component 100 effectively avoids impurity from entering drainage pipeline at this point, the impurity being mingled with is filtered again by sieve 120.Meanwhile it sieving Screen component 100 is detachable, can easily clean out the impurity in screen assemblies 100, improves maintenance efficiency, reduce maintenance at This.
