Method for reinforcing expansive soil foundation pit slope
The invention discloses a method for reinforcing an expansive soil foundation pit slope through microwaves. The method for reinforcing the expansive soil foundation pit slope through the microwaves comprises the following steps of: 1, determining a treatment area according to engineering construction requirements; 2, using a drilling machine or a vibration pile driver to drill a hole in the expansive soil foundation pit slope to a preset position, and placing a grouting pipe in the hole; 3, injecting prepared slurry into a to-be-reinforced soil body through the grouting pipe; 4, during grouting, starting a microwave heating system to accelerate early hydration of cement, so that the early strength of the slurry is formed quickly; And fifthly, after grouting is completed, continuing to conduct microwave irradiation continues on the slurry and soil body mixture, so that rapid solidification and condensation of slurry in the rock and soil body are accelerated, meanwhile, the water contentof the rock and soil body is reduced, the expansibility of the soil body is reduced, and the shear strength of the soil body is improved; and after the design standard is reached, moving to the nextdrilling hole, and repeating the steps. According to the method for reinforcing the expansive soil foundation pit slope through the microwaves, the construction period is shortened through a microwavetechnology, and the stability of the foundation pit slope is greatly enhanced.
本发明公开了一种微波加固膨胀土基坑边坡的方法。其包括以下几个步骤：一、根据工程建设需求，确定处理区域；二、利用钻机或震动打桩机在膨胀土基坑边坡钻孔至预定位置，并将注浆管置入孔内；三、将制备完成的浆液通过注浆管注入至待加固土体中；四、注浆同时，启动微波加热系统，加速水泥的早期水化，使得浆液早期强度较快形成；五、注浆完成后，继续对浆液‑土体混合体进行微波辐照，促进岩土体中的浆液快速固化凝结，同时降低岩土体本身的含水率，降低土体的膨胀性，提高土体的抗剪强度。达到设计标准后移至下一钻孔，重复以上步骤。本发明利用微波技术缩短了工期，且大大增强基坑边坡稳定性。
