Description

一种海岸边坡排水***Coastal slope drainage system 技术领域Technical field
本发明属于岩土工程、海岸工程领域，尤其涉及一种海岸边坡排水***。The invention belongs to the field of geotechnical engineering and coastal engineering, and particularly relates to a coastal slope drainage system.
背景技术Background technique
中国经济发展迅速，大量基础设施建设，然而中国大部分地区地质地形环境复杂，地质灾害频发，其中滑坡灾害对人类生产生活构成巨大威胁。大多数滑坡灾害的发生与地下水位变化有关。地下水位的上升导致滑坡体容重增加，滑面有效应力降低，抗剪强度减小，进而导致滑坡失稳。对于边坡，当坡前水位快速下降时，坡内地下水向坡外渗流，产生渗透力，增加下滑力，促使滑坡失稳。因此及时排出边坡中的地下水，保持地下水位稳定，对防治滑坡灾害与应急处理都极为关键。China's economy is developing rapidly and a large amount of infrastructure has been constructed. However, most areas of China have complex geological topography and frequent geological disasters. Among them, landslide disasters pose a huge threat to human production and life. Most landslide disasters are related to changes in groundwater level. The rise of the groundwater level causes the bulk density of the landslide body to increase, the effective stress of the sliding surface decreases, and the shear strength decreases, which in turn leads to the instability of the landslide. For a slope, when the water level in front of the slope drops rapidly, the groundwater in the slope seeps to the outside of the slope, generating seepage force, increasing the sliding force, and promoting the instability of the landslide. Therefore, timely drainage of groundwater from the slope and maintaining the stability of the groundwater level are extremely critical for preventing landslide disasters and emergency treatment.
目前山区的边坡排水方法中：水平重力式排水效率低，需要很长的钻孔，长时间使用会出现阻塞的问题；地下排水洞施工复杂，工程量大，成本高；集水井抽水需要持久的动力源，同时维护困难。The current slope drainage methods in mountainous areas: horizontal gravity drainage is inefficient and requires a long drill hole, which will cause blockage when used for a long time; the construction of underground drainage tunnels is complicated, the amount of work is large, and the cost is high; the water collection well needs long-lasting pumping The power source is difficult to maintain at the same time.
综合上述边坡排水方法，近年来提出了虹吸排水技术，边坡虹吸排水方法具有排水孔布置方便、集水能力强、截排水效果好、需要的钻孔长度小、工程建设速度快等优点，然而在使用虹吸排水方法的工程中，遇到干旱少雨季节时，地下水位降低，坡体没有水需要通过虹吸作用排出，虹吸排水***就会处于停止工作状态，溶解于水中的空气会以气泡的形式逐渐析出，虹吸管中就会不断累积空气，使虹吸管中的真空度降低，导致虹吸难以再次启动甚至虹吸现象消失。沿海地区由于交通发展的需要，往往会修建诸多沿海公路、铁路，会形成很多海岸边坡，虹吸排水技术在海岸边坡应用依然会存在上述问题。Based on the above slope drainage methods, siphon drainage technology has been proposed in recent years. The slope siphon drainage method has the advantages of convenient drainage hole arrangement, strong water collection capacity, good drainage effect, small drilling length required, and fast construction speed. However, in projects that use the siphon drainage method, in the dry and rainy season, the groundwater level decreases, and there is no water on the slope that needs to be drained through the siphon effect. The siphon drainage system will be in a stopped working state, and the air dissolved in the water will become air bubbles. The form gradually precipitates, and air will continue to accumulate in the siphon tube, which reduces the vacuum in the siphon tube, which makes it difficult for the siphon to start again or even the siphon phenomenon disappears. Due to the needs of transportation development in coastal areas, many coastal roads and railways are often built, and many coastal slopes are formed. The application of siphon drainage technology on coastal slopes still has the above problems.

The slope groundwater flows through the siphon 3 and the outlet pipe 6 and is discharged into the sea;
(3)海上波浪或潮水运动时，海水涌入水槽17中，冲击水轮叶片16，水轮叶片16转动带动转轴14和圆轮9转动，旋片11随着圆轮9转动，旋片11受到离心力和弹簧作用力，旋片11的顶端与旋片腔8内壁始终保持接触滑动，旋片11逆时针旋转，进水室7压强减小，排水管13内压强增加，虹吸管3中累积的空气被吸入 旋片腔8，而后又从排水管13排出，虹吸管3真空度增加，虹吸作用恢复，海岸边坡1正常进行虹吸排水；(3) When sea waves or tides are moving, seawater pours into the water trough 17 and impacts the water wheel blades 16. The rotation of the water wheel blades 16 drives the shaft 14 and the round wheel 9 to rotate. The rotary vane 11 rotates with the round wheel 9 and the rotary vane 11 Subject to centrifugal force and spring force, the top of the rotary vane 11 always keeps sliding contact with the inner wall of the rotary vane cavity 8. The rotary vane 11 rotates counterclockwise, the pressure in the water inlet chamber 7 decreases, the pressure in the drain pipe 13 increases, and the accumulation in the siphon 3 The air is sucked into the rotary vane cavity 8 and then discharged from the drain pipe 13, the vacuum degree of the siphon pipe 3 is increased, the siphon effect is restored, and the coastal slope 1 is normally siphoned and drained;
(4)海上波浪或潮水停止运动时，海岸边坡1发生虹吸排水，边坡地下水流经虹吸管3、出水管6排到海中。(4) When sea waves or tides stop moving, siphon drainage occurs on the coastal slope 1, and the slope groundwater flows through the siphon 3 and the outlet pipe 6 and is discharged into the sea.
