INJECTION METHOD OF SLURRY MATERIAL IN METHOD OF SLURRY SHIELD CONSTRUCTION

摘要

PURPOSE: To remove a stable quality of cut soil and cope with changes of natural ground by kneading resin, water, and oil by a specific weight ratio to then be discharged in the front of a cutter or within a compression chamber. CONSTITUTION: Oil in an oil tank 1 is force fed by a pump 2 so as to be put in a kneading tank 3, and in kneading tank 3, resin, water, and oil are kneaded at a weight ratio of 1:0.5, 0.5-1.5. Then, kneaded matter is stored in a storage tank 5 for stirring; which is then force fed to a double tube nozzle 8 after its quality control is performed by a variable quantitative pump 7. While, water in a reservoir 11 is force fed to the double tube nozzle 8 an underwater electric pump 12 via a water tank 13 after its quantity control is effected by a variable quantitative pump 14 and valve 15. These are further mixed within the double tube nozzle 8 and then discharged in the front of the cutter or within the compression chamber.
