Construction method for active drainage layer of basement bottom plate
The invention provides a construction method for an active drainage layer of a basement bottom plate. The construction method comprises the steps that S1, mortar is smeared on the surface of the basement bottom plate to form a leveling layer; s2, positioning steel bars are erected on the edge of the basement bottom plate, angle steel is welded to the tops of the positioning steel bars, and the outer edge of the basement bottom plate is excavated to form a drainage ditch; s3, a prefabricated plate is laid, a cylindrical groove is formed in the top of the prefabricated plate, a water guide groove is formed in the bottom of the prefabricated plate, and the upper edge of the ending closing opening of the prefabricated plate is flush with the lower edge of the angle steel; s4, binding floor steel bars above the prefabricated slabs, and pouring cement mortar to form a reinforced concrete layer; and S5, the reinforced concrete layer is leveled and maintained. On the basis, cement mortar can enter the cylindrical groove after being poured so as to enhance the connection strength of the reinforced concrete layer and the prefabricated slab, meanwhile, reverse osmosis water blocked by the bottom of the prefabricated slab can flow into a drainage ditch along a drainage channel formed by the water guide groove and the leveling layer, and the situation that the reinforced concrete layer cracks is reduced; and the leakage possibility of the basement bottom plate is reduced.
本申请提供了一种地下室底板主动排水层施工方法，包括：步骤S1，地下室底板表面涂抹砂浆形成找平层；步骤S2，地下室底板边缘位置支设定位钢筋，定位钢筋顶部焊接角钢，地下室底板外边缘开挖形成排水沟；步骤S3，铺设预制板，预制板顶部具有柱形槽，预制板底部具有导水槽，预制板的终止收口上沿与角钢下沿齐平；步骤S4，预制板上方绑扎地坪钢筋，浇筑水泥砂浆形成钢筋混凝土层；步骤S5，钢筋混凝土层整平、养护。基于此，水泥沙浆浇筑后可以进入柱形槽以增强钢筋混凝土层与预制板的连接强度，同时预制板底部阻截的反渗水可以沿着导水槽与找平层所形成的排水通道流入排水沟，减少钢筋混凝土层开裂的情况，降低地下室底板出现渗漏的可能性。
