摘要： PROBLEM TO BE SOLVED: To provide a building foundation with increased resistance to not only vertical seismic motion but also directional seismic motion.
SOLUTION: A method of constructing a building foundation includes constructing a stack of numerous water-permeable, cup-shaped structures under the ground below the building foundation, and interconnecting the stack of water-permeable cup-shaped constructions at each step to compact soil around and between the steps of interconnected water-permeable cup-shaped structures to construct a number of layers of water-permeable blocks under the ground.

摘要： PROBLEM TO BE SOLVED: To provide a nozzle bit capable of carrying out work preventing a water permeable cement from being reversely jetted so that the influence of reaction force resulting from tearing force of a stratum by the water permeable cement jetted from the nozzle bit jetting water permeable cement milk can be diminished to the utmost to exhibit a conical tearing function close to ideal even in such a nature of stratum as a tough clayey stratum or a stratum including a tough clayey layer and that an umbrella-shaped discoid conical structure close to ideal can be formed.
SOLUTION: The nozzle bit, used for the improvement method for the soft ground and constituted by perforating a plurality of nozzle bits at a required interval with a downward angle θ1 in the vertical direction and a lead angle θ2 in the rotational direction of the nozzle bit, is provided.

摘要： PROBLEM TO BE SOLVED: To provide a method which solves inconveniences occurring when an existing railway track constructed on a concrete surface of viaduct is removed and replaced by a railway track of a newly developed direct-coupled track type, and saves labor of transforming the viaduct surface into a surface suitable for arranging blocks for use in laying the railway track of the direct-coupled type.
SOLUTION: The method is provided for removing the existing railway track constructed on the concrete surface of the viaduct, and transforming the viaduct surface into the surface suitable for constructing the railway track of the direct-coupled type. According to the method, a cement layer is formed on the viaduct surface so as to have suitability for laying the concrete blocks which are component members for laying the railway track of the direct-coupled type, by using a nozzle bit. The nozzle bit has injection holes formed therein, which tilts at a downward angle θ1 with respect to an insertion direction into the ground and a lead angle θ2 with respect to a rotating direction.

摘要： PROBLEM TO BE SOLVED: To provide a method of maintaining and repairing ballast and a track in a labor-saving manner by using a nozzle bit developed by the present inventor, the method intending not only to reinforce ground having a roadbed built thereon while maintaining the ballast and the track fixed to sleepers as they are, but also to reinforce the railway track by injecting cement milk into the ballast, and combining the ballast with the sleepers having the track fixed thereto, the injection of the cement milk into the ballast laid on the roadbed conventionally assumed tube difficult due to heavy pressure of the track applied to the ballast.
SOLUTION: According to the method, conical disk structures are formed in the ground in multiple stages along the railway track on the railway roadbed which has been compacted, by using the nozzle bit which has a desired number of injection holes formed therein. Each injection hole tilts at a downward angle θ1 with respect to an insertion direction into the ground and a lead angle θ2 in a lead angle direction with respect to a rotating direction. Then the nozzle bit is operated in the ballast laid on the roadbed similarly to the operation of forming the conical disk structures, and the permeable cement milk is force-fitted in gaps in the ballast, whereby the ballast and the sleepers having the rail firmly laid thereon are hardened in one body to obtain a foundation floor. In this manner, the foundation floor is successively extended in a railway track direction.
