Reservoir bank slope filling area prepressing drainage system and method utilizing reservoir water pressure
The invention provides a reservoir bank slope filling area prepressing drainage system and method utilizing reservoir water pressure. A drainage body is pre-buried in a filling area of a slope soil body and connected with a drainage reinforcing device. The filling area is provided with an inverted filter layer formed by filling sand gravel; a sealing layer formed by a sealing film is laid on the upper portion of the inverted filter layer; a buffer layer is arranged on the outer surface of the sealing layer and provided with a mortar stone layer; a drill hole is formed in the position, located at the drainage body, in the filling area and internally provided with a grouting pipe; the drainage reinforcing device is located in the filling area; the drainage body is embedded into the bottom of an anchoring section sleeve of the drainage reinforcing device and is grouted and reinforced through the grouting pipe; and a one-way valve is arranged at an outlet of a free section sleeve of the drainage reinforcing device. According to the reservoir bank slope filling area prepressing drainage system and method utilizing the reservoir water pressure, an existing mortar stone slope protection parting system is optimized, cracks generated by uneven settlement are avoided, a prepressing drainage system and a water pumping system are additionally arranged on the basis of an existing mortar stone slope protection structure, and the protection problem of a reservoir area slope hydro-fluctuation belt can be solved.
一种利用库水压力的库岸边坡填土区预压排水系统及方法，边坡土体的填土区域内预埋有排水体，排水体连接排水加固装置。填土区域设有充填砂砾石构成的反滤层，反滤层上部铺设有密封膜构成的密封层，密封层外表面设有缓冲层，缓冲层上设浆砌石层。填土区域内部在定位的排水体位置处设有钻孔，钻孔内设注浆管。排水加固装置位于填土区域内部，排水体嵌套入排水加固装置的锚固段套管底部并通过注浆管注浆加固，排水加固装置的自由段套管出口设置单向阀。本发明装置及方法优化现有浆砌石护坡的分缝体系，避免不均匀沉降产生的裂缝，并在现有浆砌石护坡结构基础上增加预压排水系统和抽水系统，可以解决库区边坡消落带的防护问题。
