Compound stratum slurry shield slurry high-efficiency circulation ratio
The invention discloses a mud rock and round gravel compound stratum slurry balance shield slurry admixture selecting and proportioning, a proportioning method and a simulation device. The slurry is mainly composed of bentonite, water and an admixture, a ratio of the bentonite to the water is 0.15: 1-0.3: 1, and a concentration range of potassium methyl silicate is 4.1%-7.5%. A determination method is scientific and high in feasibility. The simulation device comprises a circulation system, a tunneling system and a pressurization system. The tunneling system is mainly composed of an air cylinder, a motor, a speed reducer, a cutterhead and an organic glass cylinder. The pressurization system mainly comprises an air compressor and an oil-water separator; the circulation system is mainly composed of a slurry storage pool and a slurry pump. According to the mud rock and the round gravel compound stratum slurry balance shield slurry admixture selecting and proportioning, the proportioning method and the simulation device, different stratum conditions can be controlled, grouting pressure, grouting speed, slurry admixtures and the like to measure basic performance parameters of the slurry are changed, field practical problems to be solved, and formation and quality of a slurry film can be observed more intuitively.
本发明公开了泥岩圆砾复合地层泥水平衡盾构泥浆外加剂选择及配比、配比方法及模拟装置。该泥浆主要由膨润土、水及外加剂三者组成，膨水比0.15：1～0.3:1，甲基硅酸钾浓度范围4.1％～7.5％。确定方法科学、可行性高。模拟装置包括环流系统、掘进系统及加压系统，掘进系统主要由气缸、电动机、减速机、刀盘及有机玻璃筒组成；加压系统主要为空气压缩机及油水分离器；循环系统主要为泥浆储备池及泥浆泵组成。该装置可控制不同地层条件、改变注浆压力、注浆速度泥、浆外加剂等测定泥浆的基本性能参数，拟解决现场实际问题,并且能够更加直观的观察泥膜的形成及泥膜质量。
