摘要： PROBLEM TO BE SOLVED: To provide a cut-off method for construction of an underground structure, which enables a bedrock section to be more accurately constructed than by excavation without timbering and a New Austrian Tunnelling Method, by constructing natural ground having an upper section with a high coefficient of permeability by a pneumatic caisson method.
SOLUTION: The natural ground 21 with the high coefficient of permeability until a leading end of a cutting edge 2 of the caisson reaches bedrock 22 is excavated by the pneumatic caisson method, so that the caisson can be settled. When the leading end of the cutting edge 2 of the caisson reaches the bedrock 22, a grout material is infilled into a void between an outer surface of a caisson skeleton 1 and the natural ground 21. Subsequently, the bedrock section is excavated by the excavation without timbering and the New Austrian Tunnelling Method. In the case of the production of sump water from the bedrock 22 during the excavation of the bedrock section, after the sump water is temporarily stopped by applying working air pressure consistent with sump water pressure, cut-off grouting is performed, and the bedrock section is excavated to a predetermined depth, so that the prescribed underground structure can be constructed.

摘要： PROBLEM TO BE SOLVED: To reduce an adverse effect on a marginal environment by increasing the efficiency of removal of dust, in a wet dust collector which collects and removes the dust produced during tunnel boring work under the ground and in a mountain.
SOLUTION: This wet dust collector 1 comprises a water storage tank 3, an introduction portion 19, a water spray portion 21, an air pipe 22, and an air blower 23. The water storage tank 3 is provided with an air bubble generator 7 for bubbling a liquid surface in a casing 5, and an air filter 20 for removing the mist of dust air. The dust air is mixed with water in two locations, that is, the water spray portion 21 and the water storage tank 3, and passes through the water in the bubbled state of the liquid surface in the water storage tank 3. Thus, the dust is firmly mixed with the water, so that dust removal efficiency can be increased. Additionally, since the air is discharged after the mist is removed by the air filter 20, the adverse effect on the marginal environment is reduced.
