摘要： PROBLEM TO BE SOLVED: To provide a cutoff apparatus which includes an elastic body of a cellular structure, and is further improved in cutoff performance. SOLUTION: The cutoff apparatus (10) is available for an underground structure which has an opening through which an excavator or the like is penetrated, for forming a tunnel or a conduit in the ground. The cutoff apparatus is composed of the elastic body (12) of the cellular structure, which is mounted on a peripheral wall surface (22) of the opening of the underground structure, and a single or a plurality of bag bodies (14) embedded in the elastic body and sequentially or intermittently arranged along a hole of the elastic body. The elastic body (12) has the hole (26) formed therein, for allowing the excavator or the like to pass therethrough, and presses the excavator or the like from around when it passed through the hole. The bag bodies (14) are inflatable or deflatable via at least one pipe by supplying fluid or discharging the same. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To keep an invert part in the dry state by constituting a water barrier bag from a flexible hollow sealed body, a water feed valve, and an air vent valve. SOLUTION: A water barrier bag A is formed of a hollow sealed body 1, and an air vent valve 2 and water feed valve 3 set on the upper surface 1a thereof. When the water barrier bag A is set on both ends of a water barrier section on an invert part, the setting is performed in the state where no water is supplied into the water barrier bag A, and after the set, the air vent valve 2 is opened to feed water into the hollow sealed body 1 through the water feed valve 3 while deaerating the hollow sealed body 1. According to this, the hollow sealed body 1 can be curved and closely fitted according to the form of a set structure to close a clearance. After the work is completed, the water in the hollow sealed body 1 is drained to reduce the weight, whereby the removing and moving work can be facilitated.

摘要： PROBLEM TO BE SOLVED: To improve water stop performance at an uneven overlap part of the excavated cross section of different circular arcs in the case of work execution of an entrance packing in a multi-circular shield tunnel. SOLUTION: A jack is disposed in a recessed part 10 of a hole wall 3 of a skeleton 4 in front of an entrance packing 6, at an uneven overlap part of the excavated cross section of different circular arcs of a multi-circular shield tunnel. When the entrance packing 6 is curved in contact with a shield machine or an outer peripheral part 7 of a segment, a jack shaft 12 is extended to press the curved part of the entrance packing 6 outward. The entrance packing 6 therefore adheres closely to the shield machine or the outer peripheral part 7 of the segment.

摘要： PURPOSE: To improve the handling properties of a segment with a bag used for excellently filling a back-filling material while reducing cost. CONSTITUTION: Bag bodies 3, to which bag members 7 consisting of a cloth material having air permeability are fitted while mutual fringes are sewn together, are mounted on the internal surfaces of sheet members 6 composed of a vinyl sheeting, etc., on the outer circumferential side of a segment body 2. Hole sections 8 communicated with filler holes 4 formed to the segment body 2 are formed to the bag members 7. Mutually adhesive fasteners 5a, 5b are set up to each fringe of the outer circumferential surface of the segment body 2 and the internal surfaces of the bag bodies 3. Rings made up of segments 1 with bags are installed at intervals in the axial direction in an excavated pit. Sections among the sheet members 6 of the bag bodies 3 and the bag members 7 are filled with grout from the filler holes 4 of the segment body 2, and the bag bodies 3 are expanded and the sheet members 6 are fast stuck on a bedrock G. Tail voids T partitioned by the bag bodies 3 are filled with a back-filling material.

摘要： PURPOSE:To effectively prevent the run-off of muddy water, sludge, and sand into a shaft by a method in which a pipe for injection is attached in parallel with the advancing direction to the periphery of a skin plate and an elastic part is attached so as to smoothen the periphery of the skin plate, including both skirts of the pipe. CONSTITUTION:In attaching an injecting pipe 3 to the periphery of a skin plate 2, an elastic part which is separated comparatively easily with advancement of excavation is used. The part 4 is an expanded urethane rubber or well-known caulking part preferably. The end portion of the part 4 in the axial and circumferential directions of a shield machine 1 is so slantedly shaped that it is not deformed abruptly and comes near the periphery of the plate 2 gradually. The contact between the entrance packing and the machine 1 can thus be improved, permitting higher shielding effect to be obtained.
