Method for reinforcing house foundation based on grouting steel pipe piles
The invention relates to the technical field of building construction, in particular to a method for reinforcing a house foundation based on grouting steel pipe piles. Digging a digging groove in the bottom soil of the building needing to be reinforced, and processing a pile hole in the bottom of the digging groove; a hollow steel pipe is inserted into the pile hole, and grouting holes are formed in the pipe wall of the steel pipe; a grouting pipe is inserted into the steel pipe, and fine aggregate concrete is poured into the steel pipe; cement paste is poured into the steel pipe; a concrete cushion layer is constructed at the bottom of the excavation groove; constructing a foundation on the concrete cushion layer; and building supporting columns are constructed on the foundation. The problems that construction cannot be carried out in a narrow space, normal production or life of a reinforced building user is affected, drilling cannot be carried out in hard stratums such as block stones and pebbles, and hole collapse is prone to occurring in construction are solved.
本发明涉及建筑施工技术领域，具体涉及一种基于注浆钢管桩进行房屋基础加固的方法。在需要加固的建筑物底部土壤中挖掘出挖掘槽，在挖掘槽底部加工出桩孔；在桩孔中插入中空的钢管，钢管的管壁上开设有注浆孔；将注浆管插入钢管，向钢管内灌注细石混凝土；向钢管内灌注水泥浆；在挖掘槽底部施工出混凝土垫层；在混凝土垫层上施工出基础；在基础上施工出建筑物支撑柱。解决了狭小空间无法施工、影响加固建筑物使用者正常生产或生活、在块石、卵石等坚硬地层不能钻进、施工中容易塌孔等问题。
