- Grouting reinforcement technique is analyzed and designed in foundation pit which were damaged by rainstorm. Heavy rains led to a deep foundation pit are soaked and some slopes were collapse and the foundation of surrounding buildings were sunken. The causes of the accident are analyzed after emergency rescue. The main reason is foundation pit lateral groundwater with high water pressure, carrying a large number of soil particles of slope to foundation pit, and led to a collapse of the upper soil. Then the foundation pit reinforcement schemes are designed, which are active area of soil grouting reinforcement and self-drilling bolt added. Grouting can be filled dense with soil that damaged by rain, improve soil shear strength, increase the bearing capacity of anchor, thereby increasing the safety factor of foundation pit. Since the sealing curtain damaged, grouting in the pit top of slope will help repair sealing curtain and to prevent buildings around foundation pit generating uneven settlement. Using the grouting technology, the foundation pit is successfully completed and can provide technical references for similar projects.
