Embodiment Construction
[0035]The technical solution of the present invention is: based on the principle of high-pressure water jet, that is, using high-pressure water generating device and using water as the working medium, after obtaining huge energy, it can be pre-installed in the soil bin partition, knife The specific nozzles and nozzles on the panel panel produce high-speed jet water jets to wash and cut the soil at different positions on the panel of the cutterhead, the back of the cutterhead and the soil bin to remove the generated mud cake or avoid the consolidation of the slag The mud cake is formed into blocks, so as to achieve the goal of synchronous mud cake prevention and shield tunneling. The use of this system also helps to improve the effect of muck improvement.
[0036] The mud cake prevention and control system of the present invention comprises: panel fixed nozzle, cutter head, shield body, earth bin partition, flushing gun, flushing point and pipeline connection, high-pressure pipe...
