Abstract
The utility model discloses a kind of speedway underpass type channel drainage system, be respectively equipped with anti-fluid barrier in the inlet and outlet of passage, the transverse direction of passage is provided with several transverse cutting ditch, the both sides of passage are provided with longitudinal drainage ditch, transverse cutting ditch is connected with longitudinal drainage ditch, and longitudinal drainage ditch is communicated with collecting well.The top in transverse cutting ditch is provided with connection and combs, in two-sided slope bottom transverse cutting ditch.The import of passage and outlet are respectively equipped with water proof band.Beneficial effect: water-proof part and water discharging part acting in conjunction, relies mainly on prevention, and row is auxiliary.By for structures such as the custom-designed anti-fluid barrier of speedway underpass type passage, water proof bands, can effectively by most of rainwater and garbage blocking outside passage; For the rainwater in admission passage, drainage system can be got rid of rapidly, effectively ensures in passage without ponding.
Description
Technical field
The utility model relates to a kind of drainage system, particularly a kind of speedway underpass type channel drainage system.
Background technology
For a long time, the speedway of China generally adopts the mode of high embankment to build, and express highway roadbed height is generally 3m ~ 4m.The speedway of the developed countries such as America and Europe generally adopts low embankment, and average height is at 0.5m ~ 1.0m.Compare low embankment, high embankment can take more soil, and that causes view isolates sense, increases the weight of the extent of injury of traffic accident, easily occurs differential settlement and slope instability etc.At present, the key restraining factors that the express highway roadbed height of China can fall all the time are exactly the interference of cross traffic.Therefore, many speedways adopt underpass type passage scheme for reducing roadbed height.But this scheme makes interconnection draining difficulty, existing drainaging scheme solely arranges gutter in passage both sides or adopts collecting well, will ponding in one to rainy day passage, have impact on the daily current of the local masses, cause bad social influence.
Summary of the invention
The purpose of this utility model is in order to solve the Poor construction quality of terrace-bank of existing speedway underpass type passage and a kind of speedway underpass type channel drainage system provided.
The speedway underpass type channel drainage system that the utility model provides is respectively equipped with anti-fluid barrier in the inlet and outlet of passage, the transverse direction of passage is provided with several transverse cutting ditch, the both sides of passage are provided with longitudinal drainage ditch, transverse cutting ditch is connected with longitudinal drainage ditch, and longitudinal drainage ditch is communicated with collecting well.
The top in transverse cutting ditch is provided with connection and combs, in two-sided slope bottom transverse cutting ditch.
The import of passage and outlet are respectively equipped with water proof band.
Waterproof shed top surface is the form of updip, and section form is triangle, and the both sides of anti-fluid barrier are provided with masonry retaining walls.
Use principle of the present utility model:
First at the anti-fluid barrier of passage two ends setup of entrances and exits, but also be provided with water proof band, anti-fluid barrier and water proof band can be got rid of precipitation in passage outside in the rainy day and can not enter in passage, the transverse direction of passage is provided with several transverse cutting ditch, the top in transverse cutting ditch is provided with connection and combs, in two-sided slope bottom it, its slope aspect tilts from centre to both sides.The rainwater worn before the minimum point of road surface under arrival can be tackled by transverse cutting ditch layer by layer, then flows in collecting well through the longitudinal drainage ditch being arranged on passage both sides, slope aspect tilts to collecting well.The last place according to local circumstance, the water in collecting well being extracted into other drainage systems or applicable draining by water pump.
The beneficial effects of the utility model:
Water-proof part and water discharging part acting in conjunction, rely mainly on prevention, and row is auxiliary.By for structures such as the custom-designed anti-fluid barrier of speedway underpass type passage, water proof bands, can effectively by most of rainwater and garbage blocking outside passage; For the rainwater in admission passage, drainage system can be got rid of rapidly, effectively ensures in passage without ponding.This system plays vital effect for the unimpeded of speedway underpass type passage, has popularizing value widely.

Detailed description of the invention
Refer to shown in Fig. 1 and Fig. 2:
The speedway underpass type channel drainage system that the utility model provides is respectively equipped with anti-fluid barrier 2 in the inlet and outlet of passage 1, the transverse direction of passage 1 is provided with several transverse cutting ditch 3, the both sides of passage 1 are provided with longitudinal drainage ditch 4, transverse cutting ditch 3 is connected with longitudinal drainage ditch 4, and longitudinal drainage ditch 4 is communicated with collecting well 5.
The top in transverse cutting ditch 3 is provided with connection and combs, in two-sided slope bottom transverse cutting ditch 3.
The import of passage 1 and outlet are respectively equipped with water proof band 6.
Anti-fluid barrier 2 end face is the form of updip, and section form is triangle, and the both sides of anti-fluid barrier 2 are provided with masonry retaining walls 7.
Use principle of the present utility model:
First at the anti-fluid barrier 2 of passage 1 two ends setup of entrances and exits, but also be provided with water proof band 6, anti-fluid barrier 2 and water proof band 6 can be got rid of precipitation in passage 1 outside in the rainy day and can not enter in passage 1, the transverse direction of passage 1 is provided with several transverse cutting ditch 3, the top in transverse cutting ditch 3 is provided with connection and combs, in two-sided slope bottom it, its slope aspect tilts from centre to both sides.The rainwater worn before the minimum point of road surface under arrival can be tackled by transverse cutting ditch 3 layer by layer, and the longitudinal drainage ditch 4 that then process is arranged on passage 1 both sides, slope aspect tilts to collecting well 5 flows in collecting well 5.The last place according to local circumstance, the water in collecting well 5 being extracted into other drainage systems or applicable draining by water pump.
