Example Embodiment
[0022] Example one:
[0023] A landfill material suitable for burying an earth pressure box, which is a mixture of cement, bentonite, fine sand, water, etc., see Table 1, which is the experimental data and experimental results of 7 different ratios given in this example. According to the experimental results: when the mass ratio of cement, bentonite, fine sand, and water is 0.1:0.2:4.7:1.5, the prepared landfill material also has good fluidity, good drainage characteristics, and rapid strength growth. It meets the requirements of earth pressure box landfill materials with its characteristics, such as easy dispersion after forming and low cost.
[0024] Table 1: Landfill material test table of Example 1
[0025]
[0026] The above test materials, the cement is Q32.5 cement, fine sand (the mass of particles larger than 0.075mm exceeds 85% of the total mass), different types of fine sand need to adjust the amount of cement, bentonite and water in a small range.
Example Embodiment
[0027] Embodiment two:
[0028] A landfill material suitable for burying an earth pressure box, which is a mixture of cement, bentonite, fine sand, water, etc., see Table 2, which is the experimental data and experimental results of 5 different ratios given in this example. According to the experimental results: when the mass ratio of cement, bentonite, fine sand, and water is 0.12:0.28:4.7:1.6, the prepared landfill material also has good fluidity, good drainage characteristics, and easy molding. The characteristics of bulk and low cost meet the requirements of earth pressure box landfill materials; when the mass ratio of cement, bentonite, fine sand, and water is 0.1:0.2:4.7:1.5, the resulting landfill material also has good flow Performance, good drainage characteristics, easy to disperse after molding, low cost and other characteristics, which meet the requirements of earth pressure box landfill materials; when the mass ratio of cement, bentonite, fine sand, and water is 0.08...
Example Embodiment
[0031] Embodiment three:
[0032] A landfill material suitable for burying an earth pressure box, which is a mixture of cement, bentonite, fine sand, water, etc., see Table 3, which is the experimental data and experimental results of 5 different ratios given in this example. According to the experimental results: when the mass ratio of cement, bentonite, fine sand, and water is 0.11:0.25:4.6:1.5, the prepared landfill material also has good fluidity, good drainage characteristics, and easy molding. The characteristics of bulk and low cost meet the requirements of earth pressure box landfill materials; when the mass ratio of cement, bentonite, fine sand, and water is 0.1:0.2:4.7:1.5, the resulting landfill material also has good flow Performance, good drainage characteristics, easy to disperse after forming, low cost and other characteristics, which meet the requirements of earth pressure box landfill materials; when the mass ratio of cement, bentonite, fine sand and water is 0.1...
