Construction method for soft soil foundation reinforcement treatment
The invention discloses a construction method for reinforcement treatment of a soft soil foundation. The construction method comprises the steps that S1, the soft soil foundation is drilled; s2, a reinforcement cage is placed in the drill hole; s3, the water pumping and grouting pipe is rotated and lowered through a stepping type pipe fitting conveying mechanism; s4, a hydraulic road roller is used for rolling the surface of the soft soil foundation; s5, multiple layers of sealing films are laid on the surface of the soft soil foundation; s6, the upper end of the water pumping and grouting pipe is connected with a water suction pump, and the water suction pump is used for discharging underground water in the soft soil; and S7, concrete is pumped into the water pumping and grouting pipe, the water pumping and grouting pipe is gradually pulled out upwards through a stepping type pipe conveying mechanism, the concrete is gradually injected from the lower portion of the drilled hole, and the reinforcement cage is located in the concrete. According to the method, underground water and air in the soft soil foundation are effectively discharged, drilling collapse is avoided, and the procedures of reinforcing the soft soil foundation and pouring the concrete pile foundation become simple and convenient. The method is suitable for the technical field of soft soil foundation construction in building construction.
本发明公开了一种用于软土地基加固处理的施工方法，S1、对软土地基进行钻孔；S2、在钻孔内下放钢筋笼；S3、通过步进式管件输送机构将抽水注浆管旋转并下放；S4、使用液压压路机对软土地基表面进行辊压；S5、在软土地基的表面上铺设多层密封膜；S6、将抽水注浆管的上端与抽水泵连接，使用抽水泵将软土内的地下水排出；S7、对抽水注浆管进行混凝土的泵入，并使用步进式管件输送机构将抽水注浆管逐渐向上拔出，使得混凝土由钻孔的下部逐渐注入，而且使得钢筋笼位于混凝土内。本发明有效地排出软土地基内的地下水及空气，并避免钻孔坍塌，使得软土地基的加固及混凝土桩基的浇筑工序变得简单、便捷。本发明适用于建筑施工中软土地基施工的技术领域。
