High-impermeability concrete drainage ditch system and construction method thereof
The invention relates to a high-impermeability concrete drainage ditch system and a construction method thereof.The drainage ditch takes a reinforced concrete collecting ditch as a whole, a composite geomembrane is attached to the outer wall of the reinforced concrete collecting ditch in a matched mode, the composite geomembrane wraps the top of a soil structure, and a cushion layer is arranged outside the composite geomembrane below the reinforced concrete collecting ditch; soil structures are arranged outside the composite geomembranes on the two sides of the reinforced concrete collecting gutter, seepage water is effectively isolated through the composite geomembranes, and smooth drainage is guaranteed. Different positions of the drainage ditch are coated with the composite geomembrane, the wall body of the drainage ditch is turned outwards after reaching the design strength, and the anti-seepage performance of the drainage ditch is greatly improved; drainage reverse osmosis pieces are embedded in the diversion corners of the drainage ditch and fixed to the drainage ditch body, water seepage is prevented, water and sundries in the drainage ditch are effectively discharged, and blocking is prevented; the stability of the combined steel formwork is ensured through the detachable fixing units and the supporting units, and the construction speed is high; the water stopping effect is good; construction is safe and convenient, and quality is easy to control; the method is especially suitable for high-grade water seepage prevention projects.
本发明涉及一种高抗渗混凝土排水沟系统及其施工方法，排水沟以钢筋砼集水沟为整体，配合其外壁贴设复合土工膜并以复合土工膜包覆于土结构的顶部，钢筋砼集水沟下的复合土工膜外设置垫层，钢筋砼集水沟两侧的复合土工膜外设置土结构，以复合土工膜有效隔离渗水，确保排水顺畅。本发明以复合土工膜包覆排水沟的不同位置，在排水沟的墙体达到设计强度后外翻，大大提高排水沟的抗渗性能；排水沟导流拐角处埋设排水反渗件并与排水沟主体固定，防止渗水，有效将排水沟内的水及杂物进行排出、防止阻塞；以可拆卸的固定单元和支撑单元确保组合式钢模板的稳定度，施工速度快；止水效果佳；施工安全、便利，质量易于控制；特别适用于高等级防渗水项目。
