Foundation reinforcement method
The invention relates to a foundation reinforcement method. The method comprises the steps that foundation reinforcement is conducted in a foundation pit through first piles in a strong reinforcementand weak reinforcement alternate mode, the reinforcement range in the foundation pit is a first strong reinforcement area and a first weak reinforcement area, the first distance below the bottom of the foundation pit is the first strong reinforcement area, and the first weak reinforcement area is from the bottom of the foundation pit to the ground; the cement mixing amount ratio of the first weakreinforcement area to the first strong reinforcement area is 7:20; the foundation reinforcement is conducted on the periphery of the foundation pit through second piles in a strong reinforcement mode,the reinforcement range of the periphery of the foundation pit is a second strong reinforcement area, the cement mixing amount ratio of the first strong reinforcement area to the second strong reinforcement area is 4:5, and therefore the unconfined compressive strength of a foundation reinforcement body reinforced in the foundation pit and the unconfined compressive strength of a foundation reinforcement body reinforced on the periphery of the foundation pit are consistent. According to the method, aiming at different conditions in the foundation pit and on the periphery of the foundation pit, a simple and feasible method is utilized, so that the strength of a reinforced soil body in the foundation pit and on the periphery of the foundation pit in engineering is approximate or accurate and consistent, the construction cost is saved, and the construction safety is improved.
本发明涉及一种地基加固方法，包括：利用第一桩采用强加固和弱加固交替的方式对基坑内进行地基加固，其中基坑内的加固范围为第一强加固区和第一弱加固区，基坑底以下第一距离为第一强加固区，基坑底至地面为第一弱加固区，第一弱加固区和第一强加固区的水泥掺量比为7:20；利用第二桩采用强加固的方式对基坑周边进行地基加固，其中基坑周边的加固范围为第二强加固区，第一强加固区和第二强加固区的水泥掺量比为4:5，从而使基坑内和基坑周边被加固后的地基加固体的无侧限抗压强度一致。该方法针对基坑内和基坑周边的不同情况，利用简单可行的办法，使工程中基坑内和基坑周边加固后的土体强度近似或精准一致，从而节约施工成本并提升施工的安全性。
