后压浆挖孔灌注桩技术工程应用

Engineering Application of the Casting Pile Technique with the Post-pressurized Mortar in the Excavated Hole

文章对后压浆挖孔灌注桩技术作了简介,并就其工程应用加以探讨,其施工要点是:做导墙挖桩孔、做砼桩放注浆管、桩底注浆、试桩。

The paper briefly introduces the casting pile technique with the pest - pressurized mortar in the excavated hole, and inquires its engineering application. The main technics of construction are constructing the excavated hole with duide wall, constructing the casting tubes for concrete mortar, casting mortar into the pile bottom and testing piles.
