摘要： PROBLEM TO BE SOLVED: To provide a device for attaching a check valve to a peripheral wall of a manhole.
SOLUTION: The device has a core drill 25, a fixture 26 for taking out the core, and a valve-insertion fixture 27. A projection 265, which is projected high gradually toward the rear, is projected and formed at the center of the inside of the semicircular part 262 in cross section of the fixture 26 for taking out the core, and the part 262 is semicircular in cross section. Then the check valve is attached by making a cutting angle, which has the thickness equal to about 90 percent of the thickness of the peripheral wall of the manhole, in the peripheral wall 15 of the manhole with the core drill 25, then by switching to the fixture 26 for taking out the core and inserting the fixture 26 for taking out the core to an annular groove formed by a core bit 251. Because of the insertion, the projection ruptures the core from its roots, and the core is taken out by pulling out the fixture 26 for taking out the core. After the core has been pulled out, the check valve is inserted and attached to the hole, from which the core has been pulled out, by rupturing the bottom of the hole by the valve-insertion fixture 27.

摘要： PROBLEM TO BE SOLVED: To provide a valve device which opens when underground soil gap water pressure outside a buried object reaches a preset pressure to allow a great amount of underground water to flow into the buried object at once through the opening.
SOLUTION: The valve device 11 is attached extrusibly to a case 21 fixed to a conduit hole 23 bored open on the peripheral wall of a manhole. The valve device 11 includes a fixing pin 19 which appears and disappears to engage separably with an engaging hole 24 formed on the case 21 to fix the valve device 11 to the case 21, a pressure detecting switch 17 which is turned on when water pressure outside the manhole peripheral wall reaches a preset value, and an electromagnet 18 which is excited when the pressure detecting switch 17 is turned on to separate the fixing pin 19 from the engaging hole 24 to release the valve device 11 from the fixation to the case 21. When the valve device 11 is released from the fixation, the valve device 11 is extruded into the manhole by water pressure outside the manhole peripheral wall to open the case 21.

摘要： PROBLEM TO BE SOLVED: To provide a method for installing a check valve on a peripheral wall of a manhole for cutting off a flow of water to the outside of the manhole from the inside of the manhole and allowing the flow of the water into the manhole from the outside of the manhole when inter-soil clearance water pressure outside the manhole increases, for preventing the manhole from floating by a liquefaction phenomenon of the ground in an earthquake.
SOLUTION: A hole is bored in the manhole peripheral wall by using a core drill. Hole boring is stopped once after reaching about 80 to 90 percent of the thickness of the peripheral wall, and a core formed of an annular groove is taken out by extracting a core bit. Then, a notch is formed again in a core taken-out hole up to reaching near an outer peripheral surface by the core bit. After notching, a rupture metal fitting 37 is installed on the tip by extracting the core bit, and the check valve 35 having a slipping-out preventive claw 15 on the outer periphery is installed in the core drill, and is pushed in the core taken-out hole 32, and a wall part 33 remaining at the bottom of the hole 32 is broken through by the rupture metal fitting 37, and is ruptured into a small piece.
