Then, sampling is made from the uppermost 5cm part and the lowermost 5cm part of the hardened cement paste and the specific gravities of the samples are measured by a testing method, and a tackifier, e.g., polyvinyl alcohol, by which the specific gravity difference of both the samles is made 0.1 or less by binding the cement particles is added in an amount of 0.2W4.0wt% on the basis of cement to form a fresh concrete having a maximum coarse aggregate dimension of 10W20mm, an aggregate amount per unit phase of 1,100W1,800kg/m
3 , an unit cement amount of 250W400kg/m
3 , an unit water content of 80W140kg/m
3 , and a porosity of 15W35%. The fresh concrete is dropped onto a given position.

摘要： PURPOSE:To cause an anchor and a drain member to reliably remain in the ground, by a method wherein the anchor is secured to the end of the drain member inserted into a casing, and after the casing is pressed in, a projecting tool is protrued from the casing. CONSTITUTION:After a beltlike drain member 2 is inserted into a hollow casing 1 and the drain member 2 is slightly pulled off through a slit formed at the forward end of the casing 1, an anchor 3 is secured to the end of the drain member 2. A projecting rod 4 is contained in the casing 1, and the casing 1 is inserted down to a given depth L in the ground in a condition in that the anchor 3 is firmly adhered to the bottom at the forward end of the casing 1. By protruding downward the projecting rod 4 when the casing 1 is pulled up, the anchor 3 and the projection part of the drain member 2 are pushed away to remain in the ground.
