粉喷桩是通过深层搅拌机械,利用水泥或石灰作为固化剂与软土强制搅拌所形成的水泥土桩或石灰桩。桩体在经过一定凝期后,其物理力学性质较之天然土有明显的变化,形成具有整体性、水稳定性和足够强度的加固地基,以提高地基的承载力、增大变形模量和减少压缩沉降。文章对软弱地基如何应用粉喷桩技术进行加固作了探讨。 DJM is through deep mixing machinery, the use of cement or lime as a curing agent and forced mixing of soft soil formed by the cement pile or lime pile. After a certain period of solidification, the physical and mechanical properties of the pile body obviously change compared with the natural soil to form a consolidated foundation with integrity, water stability and sufficient strength to improve the bearing capacity of the foundation and increase the deformation modulus and Reduce the compression settlement. The article discusses how to apply DJM technology to soft foundation reinforcement.
