SURVEY HOLE-CUM-HARDENER INJECTION DEVICE, AND METHOD OF SURVEYING GROUND AND INJECTING HARDENER FOR STRUCTURE WHERE SURVEY HOLE-CUM-HARDENER INJECTION DEVICE IS SET

摘要

PROBLEM TO BE SOLVED: To provide a survey hole-cum-hardener injection device which can safety carry out hardener injection by detecting blowout of groundwater etc.;SOLUTION: The survey hole-cum-hardener injection device 1A has: a cylindrical body 10 which communicates between the ground 3 and a space 4; and a water cutoff device 11 which is set in the cylindrical body 10, for blocking the interior of the cylindrical body 10, and provided with a female member 28. The female member 28 has a communication hole 28a formed therein, for communicating between the ground 3 and the space 4, and a water cutoff valve arranged therein, for blocking the communication hole 28a. When a male member 38 pairing with the female member 28 of the water cutoff device 11 is connected to the female member, blocking of the communication hole 28a by the water cutoff valve is released.;COPYRIGHT: (C)2010,JPO&INPIT
