Background
When the earth pressure balance shield tunnel is constructed, soil in an excavation range enters a pressure chamber under the cutting and stirring action of a cutter head, the earth output of a spiral earth output device is controlled to balance the earth input and output of shield excavation, so that the stability of an excavation surface is kept, but the states of the soil entering the pressure chamber have great difference due to different properties of stratum soil. If silt and clay enter the pressure chamber, the pressure chamber has certain fluidity and good water-stopping property, but the viscosity is higher, and the silt and the clay are easy to adhere to the cutter head to form mud cakes, so that the excavation and the soil discharge are difficult; when the gravel layer enters the pressure chamber, the water permeability is high, the fluidity is lacked, and the problems of unsmooth soil discharge or gushing of the spiral soil discharging device, too fast abrasion of a cutter head and the like are easily caused. The problems of mud cake accumulation of the cutter head, unsmooth soil discharge or gushing of the spiral soil discharging device, high abrasion of the cutter head and the like directly influence the tunneling speed and the tunneling cost of the shield machine, and the success or failure of the project can be influenced in serious cases, so that the improvement of the residual soil in the shield soil cabin is very necessary.
The slump can reflect the workability of the muck, including the water retention property, the fluidity and the cohesiveness of the muck, the muck is improved by adopting modifiers such as bentonite, foam, high-molecular polymer and the like on a shield construction site, and the workability after the muck is improved is judged through a slump test. When a muck-improved slump test is carried out, muck needs to be fully mixed with selected modifying agents such as bentonite, foam and high-molecular polymer, at present, testers generally place muck in a container and stir the muck by using a shovel, so that the mixing is very uneven, time and labor are consumed, and the test is greatly influenced.
