结合佛山市三水区某工程的实际情况,提出了高压旋喷+压力注浆固结法处理桩基下持力层溶洞的方案,并阐述了具体的施工技术与设计方法,通过静载试验表明,处理后桩基的竖向承载力满足设计要求。
Combined with the actual situation of a project in Sanshui District of Foshan City, a scheme of high-pressure rotary jet grouting and pressure grouting consolidation for the treatment of underground caverns under piles was proposed and the specific construction techniques and design methods were described. Through the static load test It shows that the vertical bearing capacity of pile after treatment meets the design requirements.
