Foundation pit dewatering and enclosing method of carbon fiber cloth reinforced concrete porous spiral pipe pile
The invention discloses a foundation pit dewatering and enclosing method of a carbon fiber cloth reinforced concrete porous spiral pipe pile. According to the foundation pit dewatering and enclosing method of the carbon fiber cloth reinforced concrete porous spiral pipe pile, the prefabricated carbon fiber cloth reinforced concrete porous spiral pipe pile is adopted, the construction is convenient, the good compression resistance and pulling resistance are achieved, and the pile can be smoothly drilled into the ground when the outer portion is wrapped with carbon fiber cloth. After the carbon fiber cloth wraps the pipe pile, the bearing capacity and stability are relatively improved, so that the concrete mark number can be reduced, the material cost is saved, meanwhile, the carbon fiber cloth serving as an electroosmosis electrode material can give full play to the advantages of an electroosmosis method in soft soil foundation pit dewatering, and compared with a metal electrode, the carbon fiber cloth is not easily affected by corrosion and is high in durability; and due to the fact that a spiral drilling mode is in tight contact with a soil body, the good electric contact working performance is provided. In the construction process, firstly, a drilling machine drills a prefabricated pipe pile into soil, then a power source is switched on for electroosmosis drainage, water is pumped out through a drainage system, the pipe pile continues to be used as an enclosing pile after dewatering is completed, and the underground water level can be regulated and controlled in time in the subsequent service process.
本发明公开了一种碳纤维布钢筋混凝土多孔螺旋管桩的基坑降水及围护方法。本发明采用预制碳纤维布钢筋混凝土多孔螺旋管桩，施工方便、具有较好的抗压与抗拔能力，并且在外部包裹碳纤维布时能够顺利钻入地下。碳纤维布包裹管桩后承载力、稳定性相对提高，从而可以降低砼标号、节约材料成本，同时碳纤维布作为电渗电极材料能够充分发挥电渗法在软土基坑降水中的优势，相较于金属电极不易受腐蚀影响、耐久性强，且由于螺旋钻入的方式与土体接触紧密从而提供良好的电接触工作性能。施工过程中先由钻机将预制管桩钻入土中，再接通电源进行电渗排水，并由排水系统将水抽出，降水完成后管桩继续作为围护桩使用，并在后续服役过程中能够及时调控地下水位。
