Abstract
The invention discloses a karst depression drainage system which comprises a drainage tunnel (6). A radial drainage ditch (1) and an annular intercepting ditch (2) are formed in a karst depression, the radial drainage ditch (1) crosses with the annular intercepting ditch (2), the radial drainage ditch (1) is connected with a bottom annular stagnant pool (4), the bottom annular stagnant pool (4) is connected with a bottom energy dissipation pool (5), and the bottom energy dissipation pool (5) is connected with a water outlet energy dissipation pool (7) through the drainage tunnel (6). The karst depression drainage system can effectively prevent the depression from generating waterlogging disasters, influence on an engineering project in the depression is reduced, the karst depression drainage system is suitable for drainage of a depression project, and is safe, reliable and convenient to maintain and manage, and the problems that in the prior art, the waterlogging disasters caused by rainfall in the karst depression project implementation process cannot be handled is solved.
Description
Technical field
The invention belongs to karst depression water discharge technology, relate in particular to a kind of karst depression drainage system.
Background technology
Karst refers to that solubility rock stratum is mainly carbonate rock distribution area, and rock is subject to water corrosion and unique geology of forming, and wherein karst depression is karst area, particularly the landform unit of huge, the ecology fragility of a kind of quantity in Rocky Desertification Region.Karst depression does not have top drainage outlet, subterranean stream usually bury very dark, nearly all Atmospheric precipitation all will by infiltrate pipeline, be input to drainage pipe.Generally, the drainability of underground piping system can adapt to local amount of precipitation and precipitation intensity, but when torrential rain and continuous rainfall amount are when excessive, because impeded drainage makes depression, waterlogging occurs.Therefore for addressing for the object of construction production of such karst depression, in depression, solve in time drainage problem particularly important.At present, take comprehensive control measures for karst depression waterlogging, utilize ecological environment measure to combine with engineering measure, ecological environment measure is to close hillsides to facilitate afforestation, conserve water and soil, prevent mudstone blocking underground karst, and hydraulic engineering measure is to expand sinkhole entrance, increases the lithic drainage bottleneck cross-section of river, and excavation open channel to dredge be main, there is no the concrete measure technology for karst depression engineering, in karst depression, implement object of construction production, easily because rainfall causes waterlogging disaster.
Summary of the invention
The technical problem to be solved in the present invention: a kind of karst depression drainage system is provided, can not solves to solve prior art the waterlogging disaster problem that rainfall causes in karst depression project implementing process.
Invention technical scheme:
A kind of karst depression drainage system, it comprises outlet tunnel, in karst depression, there are radially gutter and hoop catchwater, hoop catchwater is with radially gutter is crossing, radially gutter is connected with base circle plash, base circle plash is connected with bottom energy dissipation tank, and bottom energy dissipation tank is connected with delivery port energy dissipation tank by outlet tunnel.
Radially gutter has three at least.
Hoop catchwater has one at least.
Hoop catchwater and radially intersection, gutter are provided with energy dissipation tank, and energy dissipation tank is without top cover energy dissipation tank.
Bottom energy dissipation tank and base circle plash junction are provided with grid.
Bottom energy dissipation tank is half ground type and is provided with top cover.
The entrance width of delivery port energy dissipation tank is identical with outlet tunnel width.
Bottom energy dissipation tank and outlet tunnel junction are provided with energy dissipating and hinder husky step.
Energy dissipating hinders the 20%-30% that husky shoulder height is outlet tunnel height.
Beneficial effect of the present invention:
The flood segmentation that hoop catchwater of the present invention collects enters respectively radially in gutter, every section of gutter design flood discharge calculates according to actual catchment area, hold concurrently one of sediment trapping energy dissipation tank of energy dissipating is set in hoop catchwater and junction, gutter radially, current after energy dissipation tank sediment trapping and energy dissipating enter depression base circle plash by gutter radially, flow into again bottom energy dissipation tank, the Main Function of bottom energy dissipation tank is energy dissipating and collects silt, for guaranteeing safety, the extreme case stopping up according to karst region lower channel, the outlet tunnel that design is connected with bottom energy dissipation tank, by outlet tunnel, water is discharged to delivery port energy dissipation tank, water is drained into closing in river or depression lower than this depression by delivery port energy dissipation tank, the present invention can effectively prevent generation waterlogging disaster in depression, reduce the impact on object of construction production in depression, the present invention is applicable to the draining of depression engineering, and safe and reliable, be convenient to maintenance management, solve prior art and can not process the waterlogging disaster problem that rainfall causes in karst depression project implementing process.
