摘要： PROBLEM TO BE SOLVED: To provide a leaked air recovery device for use in a caisson method, which is simple in structure, recovers leaked air leaking outside from a caisson work chamber, and preferably returns air contained in the leaked air to the atmosphere and groundwater to the ground, respectively, without fail, by separating the former from the latter.
SOLUTION: The leaked air recovery device is formed of: leaked air recovery holes 24 opened in a peripheral surface of a caisson body 11 at locations above a cutting edge portion 14; leaked air recovery passages 25 each having one end thereof tied to the leaked air recovery hole 24 and the other end thereof communicating with the atmosphere; air feeding passages 26 each having one end thereof tied to the leaked air recovery passage 25 at a location close to the leaked air recovery hole 24; and a compressed air feeding means (e.g. an air compressor 18) tied to the other end of each air feeding passage 26. The leaked air recovery holes 24 are formed in the peripheral surface of the caisson body 11 at a plurality of locations along the horizontal direction. Further the leaked air recovery device has a groundwater returning means (e.g. a separating reservoir tank 31) arranged across each leaked air recovery passage 25 at an end on an atmosphere communicating side.

摘要： PROBLEM TO BE SOLVED: To reduce an embedded depth of an earth retaining wall, by preventing settlement and drying-up of a well of the surrounding ground by excessive pumping of underground water.
SOLUTION: In this ground excavation method, first of all, an air injection well 2 is arranged in the ground 3 so as to surround an excavation expected area 1, and the earth retaining wall 10 is built up along a boundary of the excavation expected area 1 (Step 101). Next, the boundary ground 6 sandwiched between the lower ground 4 positioned under the excavation expected area 1 and the surrounding ground 5 adjacent to the side of the lower ground, is changed to the unsaturated ground from the saturated ground by injecting air into the ground 3 via the air injection well 2, and water permeability of the boundary ground 6 is reduced (Step 102). Next, while pumping the underground water from a pumping well 9 arranged in the excavation expected area 1 in such a state, and while supporting earth pressure by the earth retaining wall 10, the excavation expected area 1 is excavated (Step 103).

摘要： PURPOSE:To prevent the infiltration and permeation of underground water into the underground cavity of a mine, etc. by feeding air, an inert gas, etc. into the cavity from the outside and holding the internal pressure of the cavity at a value higher than external ambient pressure. CONSTITUTION:Roads 8, 9, 10 communicated with the underground cavity 2 of a mine, etc. are sealed with pressureproof plugs 5, 5', 5'', and fine cracks 6 communicated with ground surface are sealed. Air, an inert gas, etc. are force-fed into the cavity 2 through a pipe 3 by a compressor 4. The internal pressure of the cavity is held at a value higher than external ambient pressure at all times. Accordingly, the infiltration and permeation of underground water into the cavity from a stratum can be prevented.

摘要： PROBLEM TO BE SOLVED: To surely prevent the air in a work chamber from leaking to the outside of a caisson body automatically without a need for human labor. SOLUTION: The air leakage prevention device 10 in a pneumatic caisson method includes an underground water pressure detecting means (water pressure metering sensors 28a-28d) detecting underground water pressure Pw of the ground G near a cutting edge of a blade 14 of a caisson body 11, an in-caisson actual air pressure detecting means (an air pressure metering sensor 30) detecting an in-caisson actual air pressure Pc inside the work chamber 16, and a pressure control means (a controller 35). The pressure control means sets a standard in-caisson air pressure P1 in the work chamber 16 for obtaining the water level inside the work chamber that can prevent the air from leaking to the outside of the blade 14 based on the underground water pressure Pw detected by the underground water pressure detecting means (28a-28d), and adjusts the air pressure inside the work chamber 16 so that the in-caisson actual air pressure Pc can come closer to the standard in-caisson air pressure P1.
