Hillside drainage system with underneath-penetrating box culvert
The invention discloses a hillside drainage system with an underneath-penetrating box culvert, and belongs to the technical field of side slope drainage. The device comprises an intercepting ditch, a sand blocking pool, a water collecting vertical shaft, a stilling pool, a drainage box culvert, an apron and an anti-scour groove, the intercepting ditch parallel to the water conveying box culvert is arranged at the slope toe and is positioned above the water conveying box culvert; the sand blocking pool is arranged in a natural river or a lower local terrain position, is communicated with the intercepting ditch and is used for collecting slope rainwater, depositing large-particle-size bed load gravel and enabling the collected and filtered rainwater to enter the stilling pool through the water collecting vertical shaft; the water collecting vertical shaft is arranged on the inner side of the water conveying box culvert and communicated with the sand blocking pond. The stilling pool is arranged at the bottom of the water collecting vertical shaft; the drainage box culvert is arranged below the water conveying box culvert, is communicated with the water collecting vertical shaft and transversely penetrates through the water conveying box culvert; the apron and the scour prevention groove are sequentially arranged at a downstream outlet of the drainage box culvert. Surface water on the slope surface can be effectively removed, box culvert foundation failure caused by rain wash is avoided, and therefore safe operation of a water conveyance project is guaranteed.
本发明公开了一种下穿箱涵的山坡排水系统，属于边坡排水技术领域。它包括截流沟、拦砂池、集水竖井、消力池、排水箱涵、海漫及防冲槽；所述截流沟傍山平行输水箱涵布置于坡脚且位于输水箱涵上方；所述拦砂池设置于自然河沟或局部地势较低处与截流沟连通，用于汇集坡面雨水并沉积大粒径推移质砂石并将收集过滤的雨水通过集水竖井进入消力池；所述集水竖井布置于输水箱涵的内侧与拦砂池连通；所述消力池设置于集水竖井底部；所述排水箱涵布置于输水箱涵底下与集水竖井连通并横穿输水箱涵；所述海漫和防冲槽依次设置于所述排水箱涵下游出口。本发明能够有效的排除坡面的地表水，避免雨水冲刷导致箱涵基础失效，从而保证输水工程安全运行。
