摘要： PROBLEM TO BE SOLVED: To provide a method of constructing an arch culvert capable of easily depositing shotcrete and taking measure against water discharge on the outer periphery thereof without assembling an external scaffold and without impairing landscape.
SOLUTION: In this method of constructing an arch culvert, a plurality of timbering of H-shape in cross section are installed at intervals while the flanges thereof are positioned parallel to the mine shaft of the arch culvert to be constructed. A water conducting sheet and a net covering the surface of the water conducting sheet which faces the inside of the arch culvert to be constructed are arranged so that the water conducting sheet is brought into contact with the inner surfaces of the flanges disposed further on the outer side than the arch culvert to be constructed so as to close the intervals between the timbering. After the shotcrete is sprayed at the portion where the water conducting sheet and the net are overlapped with the flanges, the shotcrete is sprayed on the water conducting sheet through the net.

摘要： PROBLEM TO BE SOLVED: To provide a method for comparatively easily removing a steel pipe without using any specially structured pipe body. SOLUTION: An H-shaped member is used for an arch type timbering arranged along a tunnel inside face, and the timbering 501 is installed just in front of a present face 521. A steel outer pipe 24 is placed in the natural ground D at a predetermined tiling angle upward from the lower side of the timbering 501. In the outer pipe 24, a third terminal pipe 24e is arranged so that the rear end side is slightly protruded from the face 521. In the first-third terminal pipes 24c-24e, thin parts 24i are arranged in the vicinities of connection parts. Before excavating forward from the present face 521, vibration or shock is applied to the end part of the third terminal pipe 24e protruded from the face 521 by means of a breaker or the like, so that the third terminal pipe 24e is broken from the thin part 24i so as to be removed.

摘要： PROBLEM TO BE SOLVED: To provide a ground reinforcing construction method, in which the linearity of a pipe body inserted into a ground is ensured easily and the buried pipe body need not be extracted and removed. SOLUTION: The ground reinforcing construction method is executed in order of a drilling process, a core-material inserting process and a fixing-material injection process, and a reinforcing section is fixed and buried into a ground finally. In the drilling process, an inner pipe rod 22, in which a drill bit 20 is installed at a front end, an outer pipe 24, in which the inner pipe rod 22 is housed, and a drifter 42 are used. A hollow pipe material made of a fiber-reinforced synthetic resin or polyvinyl chloride is employed as the outer pipe 24, and the outer pipe 24 is composed of the quality of a material capable of being excavated by an excavator. The outer pipe 24 is inserted into a drilled pit 62 by a front drawing system. When the outer pipe 24 is inserted into the ground 60, a part of the drill bit 20 and the inner pipe rod 22 are extracted, the inside of the outer pipe 24 is cleaned, and a core-material insertion process, in which a core material 64 is inserted into the outer pipe 24, is executed. When the insertion of the core material 64 is completed, a fixing-material injection process is conducted. Since an injected fixing material 66 has curability, the fixing material 66 is cured with the lapse of time.

摘要： PROBLEM TO BE SOLVED: To provide a method for predicting settlement in a relatively simple manner when excavation of a tunnel is carried out by adopting an auxiliary method.
SOLUTION: The method for predicting the settlement is available in excavation of the tunnel by adopting the auxiliary method employing longer section preliminary installed works, leg reinforcing works, etc., and setting timbering on an excavated wall surface. According to the method, the settlement is predicted based on a ground characteristic curve A showing the relationship between timbering internal pressure and wall surface deformation, and a timbering characteristic curve B showing the relationship between the timbering internal pressure and the settlement. Reinforcement in a cross sectional direction, by virtue of execution of the auxiliary method is reflected on the natural ground characteristic curve A as an arch effect, and reinforcement in a longitudinal sectional direction, by virtue of execution of the auxiliary method is reflected on the timbering characteristic curve B as a beam effect.
