摘要： PROBLEM TO BE SOLVED: To assemble and disassemble an earth retaining wall, a container, and a bank body with excellent workability using a liner plate, and to provide the tensile strength required for a large structure. SOLUTION: A circumferential flange 12 and an axial flange 13 having connection holes are provided in four sides of a corrugated steel plate 11 which is curved in an arc shape. The circumferential flange 12 is projected in the curved outer circumferential side, and the connection holes 15 in the axial flange 13 are provided in an outer circumferential groove part of the corrugated steel plate 11. A notch 17 of the shape to prevent a wire from being detached is preferably provided in a part of the outer circumferential groove part of the axial flange 13. The liner plates 1 are connected to each other by bolts in the vertical and right-to-left direction to make a cylindrical structure, and the wire is wound for tightening, if necessary. The assembling and disassembling works can be performed only on the outer side of the cylindrical structure to improve the workability, and the number of bolts to be used for joining can be reduced.

摘要： PURPOSE:To shorten the term of work and reduce the cost of execution by easily executing an avalanche preventing fencing. CONSTITUTION:Steel materials 21 for mounting are joined with the lower end sections of main materials 11 installed at intervals respectively, and steel materials 22 for pull-out resistance are stretched and joined onto top faces among each steel material 21 for mounting. Steel materials 23 for slide resistance are stretched and united onto rears among sections near to the lower ends of each main material 11. Steel materials 25 for mounting are connected at the lower end sections of bearing materials 13, and steel materials 26 for the bearing power of a ground are stretched and joined onto rears among each steel material 25 for mounting. When snow pressure P1 is applied, the steel materials 22 for pull-out resistance apply pull-out resistance Q2 to the main materials 11. The steel materials 26 for the bearing power of the ground transmit the bearing power of the ground Q3 over the bearing materials 13. The steel materials 23 for slide resistance apply slide resistance force Q4 to the main materials 11. Each member can be assembled by bolts and nuts. Concrete need not be placed. All materials can be transported by manpower up to places near by the position of execution including foundation members.

摘要： PROBLEM TO BE SOLVED: To ensure work space in the water by removing mud deposited on the bottom of water without a problem of water contamination by use of a structure which is good for work execution and can be easily removed after the completion of works in the case of constructing a bridge pier. SOLUTION: Corrugated sheets 17 with a radius enough for ensuring the work space in the water are connected to each other in the horizontal circumferential direction and in the vertical direction to assemble a corrugated pipe 18, and a knife edge member 19 made by a steel plate is fixed to the lower end of the corrugated pipe 18 to construct a water mudiness preventing steel frame. The steel frame is set in the mud 14 at the bottom of the water, thereby removing mud in the range surrounded with the steel frame. This setting of the steel frame and removal of mud 14 are performed until reaching the top of the foundation 13. In the case of ensuring the work space 1 in the water in the periphery for reinforcing the existing underwater bridge pier 11, the corrugated pipes 18 are assembled in such a manner as to surround the underwater bridge pier 11.

摘要： PURPOSE:To make it possible to install an opening/closing member for resting arranged in a shaft lining material at any level in a shaft and enable ascenders and descenders to safely and easily ascend and descend in the shaft by attaching the opening/closing member to a foot bar and vertical framing bars of a ladder for ascending and descending so that the member may be freely connected and disconnected from the ladder. CONSTITUTION:A fitting 5 having grooves fitting vertically extending vertical framing bar and foot bar is pivoted through a vertical shaft 6 to the base end part of one end part located in the cross direction of an opening/closing member 2 for resting arranged in a shaft lining material 1. Next, a foot bar 8 and one vertical framing bar 9 of a ladder for ascending and descending fixed to the shaft lining material 1 are fitted into each fitting groove of the fitting 5 so that they may be freely connected and disconnected. An engaging bracket 10 attached to the base end of the other end part in the cross direction of the opening/closing member 2 for resting is engaged with the foot bar 8, and freely disengaged by an operating lever 11 for releasing the engaging bracket.

摘要： PURPOSE:To permit the compaction of soil and sand by a traveling type compactor by a method in which a front plate and a back plate are set on the setting position of a box-shaped retaining wall and connected with a connec tor, and soil is packed up to the upper part of the connector in such a way as to eliminate projections on the upside of the soil. CONSTITUTION:In constructing a fabricated type steel box-shaped retaining wall with filling soil and sand, a steel front strut 1A with an L-shaped front supporter 11 and a back strut 3A are set bilaterally at an interval on a cobble stone layer 9 and a soil layer 10. A corrugated steel front plate 2 and a back plate 4 are set and fixed between the strut 1A and the back strut 1B, and the strut 1A and the back strut 3B are connected with a corrugated steel plate connector 5. A filling soil 6 and back-filling soil 18 are packed to the upper part of the connector 5 and compacted by a traveling type compactor 7. The same construction work is made for laminating the compacted soil layers to build up a retaining wall.

摘要： PROBLEM TO BE SOLVED: To solve a problem of the deformation of an earth retaining wall of a rectangular shaft making use of liner plates to the inside thereof by earth pressure without increasing any reinforcing member. SOLUTION: Linear liner plates 2 with grooves in a corrugated steel plate section are arranged upward and downward, and both up and down ends of each of the liner plates 2 are supported by reinforcing members 3. Flanges adjacent to both right and left of each of the liner plates 2 are connected to each other with bolts, if necessary. The length of the lower liner plate 2 is shortened in comparison with the upper part of a shaft, and it is favorable that an interval between the reinforcing members 3 is narrowed.

摘要： PROBLEM TO BE SOLVED: To make up for the shortage of tensile strength when having assembled a vessel or a bank with a liner plate. SOLUTION: A notched area whose shape is preferably designed to prevent a strip from coming off, is provided in one to three locations along the groove on the outer periphery of a flange in the axial direction of a liner plate 1. This liner plate 1 is jointed with a bolt in every direction, thereby forming a cylinder-shaped structure. The strip 2 is wound up along the groove on the outer periphery of the liner plate 1 and fastened. The strip 2 is so shaped that it may run along the groove of the outer periphery of the liner plate 1. Favorably, the strip 2 is connected with an anchor member which slants a bearing surface and a through hole in conformity with the direction of the strip 2 and fastened. So as to uniform the tensile force, the strip 2 is connected in a plurality of locations on the outer periphery and fastened. The number of winding of the strips 2 is reduced at the upper part while it is increased at the lower part. This construction makes it possible to reduce the number of bolts used when they are jointed to a satisfactory extent.
