FILLING DEVICE, FILLING METHOD, PLATE INSERTION METHOD, AND ELEMENT INSERTION METHOD |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a filling device and a filling method, which allow a long cavity formed in the ground in approximately horizontal direction to be filled with a curable filler under accurate pressure control even for a long filling distance; and a plate insertion method and an element insertion method using the filling method. <P>SOLUTION: A filling method allows a space in a natural ground 400 surrounded by a flange plate 152 and a halved guide pipe 41 which are long in approximately horizontal direction to be filled with a curable filler 91. An injection bag 90 for injecting the filler 91 is arranged in the longitudinal direction X of the halved guide pipe 41, and a pressure control hose 81 for transmitting the pressure between the injection bag 90 and a pipe inner surface 41a in the longitudinal direction X is arranged between the injection bag 90 and the pipe inner surface 41a in the longitudinal direction X of the halved guide pipe 41. Under pressure control based on the pressure in the pressure control hose 81, the filler 91 is sequentially injected from an arrival shaft side to a start shaft side of the injection bag 90. <P>COPYRIGHT: (C)2013,JPO&INPIT |
