The present invention relates to a jet grouting method for ground improvement (PSMG), and the purposes of the present invention are to increase a ground improvement range by improving liquidity of a ground conditioner, cutting and collapsing the ground using an extra-high pressure jet and a rotary type extended injection arm, and simultaneously closely filling a gap with the ground conditioner, and to improve (reinforce) the ground for increasing a ground improvement range for expressing predetermined strength in a short time. The jet grouting method for ground improvement, comprises: a step of punching the ground up to a planned depth by injecting high pressure construction water into the rotary type extended arm; and a step of reinforcing the ground, wherein a consolidated body is formed in the ground by injecting an environment-friendly ground conditioner with high pressure into the rotary type extended injection arm, and rotating, drawing, and raising the rotary type extended injection ...

The present invention relates to an elastic repair tube in which copper powder is impregnated and a non-excavating type water and sewage repair method using the same. The purpose of the present invention is to provide an elastic repair tube in which copper powder is impregnated, which is thermally cured in a short period of time at a low temperature of about 80°C to repair an old pipe, and a non-excavating type water and sewage repair method using the same. The elastic repair tube is integrally formed on an inner wall of an old pipe by thermal curing to repair and reinforce the old pipe. The elastic repair tube (10) is configured such that a thermosetting resin composition is impregnated in a tube sheet (11), wherein the thermosetting resin composition consists of: a base material consisting of 60 to 70 wt% of low viscosity bisphenol F-type epoxy resin, 25 to 35 wt% of a cross-linking agent, 3 to 7 wt% of copper powder and 1 to 2 wt% of an anti-foaming agent; and a curing agent consisting ...
