Abstract:
In Jingta Tower project of Tianjin, the support and protection structure foundation pit is a diaphragm wall integrated two walls together and high-pressure rotary jet grouting pile is used as water-stop curtain wall. GDP-22 high-pressure jet drill is adopted for high-pressure jet grouting to form a solidified structure with certain strength in soil. Some construction problems, such as pile forming failure, drill burying, slurry discharge, blocked and frozen pipeline, etc., are treated properly.
