High fill bottom drainage system and construction method
The invention discloses a high-fill bottom drainage system and a construction method, which comprises a main blind ditch, a secondary blind ditch and a branch blind ditch which are arranged according to the surface catchment area and flow rate, a gully with large catchment area and flow rate, a low-lying ditch which is provided with the main blind ditch along the main gully, and a small gully or the low-lying ditch which is provided with the secondary blind ditch, branch blind ditches should be arranged for spring water and seepage at exposed positions by combining the field terrain; the system further comprises a spring opening drainage structure and a horizontal drainage layer structure, the spring opening drainage structure is provided with spring opening blind ditches according to spring opening grouping to be connected with the main blind ditches, the horizontal drainage layer structure is arranged in a gravel pile or dynamic compaction replacement treatment area, and a horizontal drainage layer is arranged on the surface of the original foundation to be connected with the blind ditch drainage network. A plurality of underground water level monitoring pumping wells are arranged at the connecting part of the main blind ditch and the secondary blind ditch and the downstream part of the main blind ditch; according to the high-fill bottom drainage system, the drainage requirement can be effectively met under the condition that underground water supply sources of a high-fill field area are rich, and meanwhile the expected effect of drainage monitoring can be achieved.
本发明公开一种高填方底部排水系统及施工方法，包括按地表汇水面积和流量设置主盲沟、次盲沟及支盲沟，汇水面积和流量大的冲沟、低洼沟渠沿主要冲沟设置主盲沟，在小冲沟或低洼沟渠设置次盲沟，结合场地地形对出露处的泉水和渗流应设置支盲沟；还包括泉眼排水构造和水平排水层构造，泉眼排水构造根据泉眼分组设置泉眼盲沟连接主盲沟，水平排水层构造为在碎石桩或强夯置换处理区域，原地基表面设置水平排水层与盲沟排水网络连接；主盲沟和次盲沟连接部位、主盲沟下游部位设置若干地下水位监测抽水井；本发明的高填方底部排水系统，在高填方场区地下水补给来源丰富的情况下可有效满足排水需求，同时对于排水的监测也能达到预期效果。
