摘要： PURPOSE: To improve reliability, to simplify the control of a forcible feed amount and to improve durability without lowering strength for a long period of time by mixing the two liquids of respectively specified constitution near a ground mountain by two flow passages and backfill-grouting them. CONSTITUTION: The liquid A composed of 100 pts.wt. of alumina cement, 20-200 pts.wt. of slag powder and water and sand or clay slurry is constituted. Also, the liquid B composed of 0-300 pts.wt. of normal Portland cement to 100 pts.wt. of the alumina cement in the liquid A, 30-200 pts.wt. of gypsum, 5-60 pts.wt. of calcium hydroxide, 20-200 pts.wt. of the slag powder and the water and the sand or the clay slurry is constituted. Then, 50% pts.wt. of the liquid A is supplied to the flow passage A, 50% pts.wt. of the liquid B is supplied to the flow passage B and both liquids A and B are merged and mixed near an ejection port and backfill-grouted to the tunnel ground. Thus, a mixture is not diluted, materials are hardly separated and the reliability is improved.

摘要： PURPOSE:To make is possible to shorten spray distance, by providing a constriction part reducing the area of a flow passage to a spray nozzle pipe for a construction method for spraying concrete and providing an air suction port to the pipe wall of a section through which contraction flows from said throttled part. CONSTITUTION:For example in a spray nozzle pipe wherein construction parts and air suction ports are constituted in two stages in series, concrete M fed under pressure flows so that a coarse particle part L runs through the central part of the pipe 18 and a fine particle part S flows along the pipe side wall thereof at first. The concrete is converged by a first stage constriction part 20 to flow as contraction. Pressure is lower than atmospheric pressure in this contraction section and air is taken in the pipe 18 from a first stage air suction port 24 to lower recovery pressure. Further, turblent flow generates in the downstream side of the contraction and the coarse particle part L and the fine particle part S are uniformly mixed. both parts L, S are mixed in a level increased as compared with the previous time by a second stage construction part 22 and a second stage air suction port 26. By this method, the concrete is uniformly mixed and spray pressure is lowered and, therefore, operation can be performed in a short spray distance.
