Method for reinforcing foundation by rigid sleeve valve pipe pile
The invention discloses a method for reinforcing a foundation by a rigid sleeve valve pipe pile. According to the method for reinforcing the foundation by the rigid sleeve valve pipe pile, on the basis of traditional vertical grouting reinforcement and steel pipe pile reinforcement, a structure of a steel pipe pile is changed, a large-diameter rigid sleeve valve pipe is formed, then the large-diameter rigid sleeve valve pipe is utilized, and a special grouting plug is used for performing segmented and graded targeted grouting on a stratum. Targeted grouting reinforcement of the stratum is achieved, and the function of a traditional steel pipe pile can be achieved. According to the method for reinforcing the foundation by the rigid sleeve valve pipe pile, procedures of grouting and repeated drilling in steel pipe pile construction are avoided, and the cost of materials such as sleeve valve pipes for grouting can be saved.
本发明公开了一种刚性袖阀管桩加固基底的方法，其在传统的垂直注浆加固、钢管桩加固的基础上，改变钢管桩结构，形成大直径刚性袖阀管，然后利用大口径刚性袖阀管，使用特制注浆塞对地层进行分段、分次靶向注浆，既实现了靶向注浆加固地层，又能实现传统钢管桩的作用。此种方法不仅避免了注浆和钢管桩施工重复钻孔的工序，而且可以节省注浆用袖阀管等材料的费用。
