Pile Foundation Construction on Complex Terrain in Longhu Town of Zhengzhou

Abstract:

The construction site of the cast-in-place pile foundation near Shengda University’s complex building in Longhu Town, Xinzheng, Zhengzhou, is located on a complex terrain, and spans an existing slope with an elevation difference of 8.5m. The composite soil nailing wall was used to retain the slope permanently. The grouted pile was used for the down-slope pile with the manual Luoyang shovel used for construction of the upper section of the pile and the direct circulation drilling for the lower section. Horizontally buried PVC pipes were used to make semi-pile circulating holes with the remaining completed by are grouted pile drilling. Good construction results have been achieved, providing reference for similar projects.
