Constructing method of underground continuous wall
专利汇可以提供Constructing method of underground continuous wall专利检索，专利查询，专利分析的服务。并且PURPOSE: To excavate gravel up to large depth, by building a cylindrical locking pipe produced by mounting a PVC pipe and two cylindrical bags in resin in the longitudinal direction of a flank to an end portion of an excavation ditch, which one end is U-shaped, and by filling a fluid, such as, water, etc. in the cylindrical bags.
CONSTITUTION: An excavation ditch 1, which one end is U-shaped, is formed in the ground by means of a bucket system excavator, and a cylindrical locking pipe 2 manufactured by installing a PCV pipe 3 and two cylindrical bags 4 in resin along the longitudinal direction is built to the U-shaped end portion. The bags are expanded by filling a fluid 8, such as, sand, water, etc. in the bags 4 in order to block triangular voids 7. Sand is beforehand filled into the pipe 3, concrete 9 is placed to the excavation ditch 1 while the pipe 3 is buried at an approximate centeral location of the thickness of the concrete 9. After the concrete 9 is hardened, the fluid 8 is removed from the bags 4, and the bags 4 are faded. The locking pipe 2 is extracted while the pipe remains as it is by using a jack, the next excavation ditch 10 is continuously mounted from a location where the pipe 2 is extracted and similar work is repeated.
