Desludging recovery method in the high-pressure injection system ground improvement and its desludging recovery unit

摘要

To provide a high-pressure injection system ground improvement in existing structures immediately below and ground of the surrounding order to eliminate it from lead to extremely serious situation in can not use the existing structures, hydro ejected from the hole providing hydro recovery method and recovery apparatus desludging using the apparatus for recovering without leaking to the surroundings. Using the A high-pressure injection system ground improvement construction machine 1, a cylindrical solid sintered body in to fill the existing structures directly under or Insert and curing material the tube rod 5 in the excavated hole in the ground of the ambient ground The in ground improvement of construction, provided with a trough-like hydro receiving tank 2 to the hole 13 to be connected is formed in the bottom plate 11 to seal the tubular structure sealing material 14 to the upper end of the drilled hole in the ground, the desludging Place the receiving vessel 2 to the lower portion of the construction machine 1, and pressed hydro receiving vessel 2 in the construction machine 1 from above, when cutting the ground hydro receiving vessel without leaking hydro ejected from the hole around is hydro recovering method using hydro recovery apparatus incorporated into the 2.
