Construction process of underground drainage system under high fill
The invention relates to the technical field of drainage system construction, and discloses a construction process of an underground drainage system under a high fill, which comprises the construction of a main blind ditch, a secondary blind ditch and a branch blind ditch, and the same construction procedures of the main blind ditch, the secondary blind ditch and the branch blind ditch comprise ditch excavation, ditch bottom leveling, ditch drainage, drainage and drainage. After the bearing capacity of the dug ditch is detected to be qualified, geotextile is laid, and gravel is filled; the construction procedure of the secondary blind ditches and the branch blind ditches further comprises the step of laying plastic blind ditches after the geotechnical cloth is laid, the construction of the secondary blind ditches further comprises the step of paving broken stone hardcore layers before the plastic blind ditches are laid and paving inverted filter layers and water-permeable geotechnical cloth after the broken stones are filled, and precipitation tanks are arranged at the intersections of the branch blind ditches and the main blind ditches; the construction process of the main blind ditch further comprises the steps that before the geotechnical cloth is laid, a concrete cushion layer and a reinforced concrete bottom plate are sequentially poured in the ditch, a masonry ditch wall is constructed, after the geotechnical cloth is laid, a broken stone cushion layer is laid, an HMMP drainage pipe is laid, and finally a coarse-grained stone drainage body is constructed.
本发明涉及排水系统施工技术领域，本发明公开了一种高填方下地下排水系统施工工艺，包括了主盲沟、次盲沟以及支盲沟的施工，主盲沟、次盲沟以及支盲沟的相同施工工序包括了开挖沟渠，平整沟渠底部，对挖好的沟渠进行承载力检测合格后，铺设土工布，填充碎石；次盲沟和支盲沟的施工工序还包括了在土工布铺设后的铺设塑料盲沟，次盲沟的施工还包括了塑料盲沟铺设前的摊铺碎石垫层以及填充碎石后的铺设反滤层和透水土工布，在支盲沟和主盲沟的交汇处设置沉淀槽；主盲沟的施工工序还包括了在土工布铺设前的在沟渠内依次浇筑混凝土垫层和钢筋混凝土底板，施工浆砌石沟壁以及在土工布铺设后的摊铺碎石垫层，以及铺设HMMP排水管，最后施工粗粒石排水体。
