摘要： PROBLEM TO BE SOLVED: To simplify a structure of a soil retaining panel and improve the ease of use by fixing a binding plate at a position where a groove opening in an end part of a vertical beam having a groove fixed on fringes on both sides of a face plate is blocked and providing a connection pin of upper and lower panels in an end part of the vertical beam by utilizing the binding plate. SOLUTION: Vertical beams 1, 1 are fixed in the vertical direction along fringes on both sides of an inner face of a face plate which is formed in such a manner that it has the same size and shape as a soil retaining panel and a plurality of horizontal reinforcing rigid members 2 are fixed in parallel across an interval in the right and left directions and in the vertical direction between the vertical beams 1, 1 on the right and left. The vertical beam 1 is provided with a groove 16 of which front is opened in the vertical direction, and a binding plate 4 is fixed at a position where an opening of the groove 16 in an upper end part and a lower end part is blocked by welding. A connection pin 7 which connects soil retaining panels which are accumulated in the vertical direction is provided in such a manner that it faces up or down in at least one part of the upper end part and the lower end part of the vertical beam 1 by utilizing the binding plate 4. The connection pin 7 is inserted into the groove 16, and a set screw 6 is inserted into a through hole 4a in a condition in which a stopper comes into contact with an end face of the vertical beam 1 and is screwed in a screw hole of the connection pin 7.

摘要： PROBLEM TO BE SOLVED: To provide a strut operating tool capable of surely and smoothly carrying out rolling operation of a strut. SOLUTION: A waiting operating tool 7B has a first strut corbel 21 and a second strut corbel 22 as one body on the lower end of a bar material 15. The first strut corbel 21 is narrow and has an upward projection on the front end (wale member 3 side) and an arc-shaped corbel surface on the bar material 15 side. The second strut corbel 22 is formed in the shape of a plate and has the upward projection on the front end. When the waiting operating tool 7B is pulled out by placing a strut corbel 20 thereof under a strut 4, the strut 4 is lifted up by the first strut corbel 21 of the strut corbel 20 and the second strut corbel 22 and, at the same time, it is rotated upward with a second horizontal hinge bearing shaft 8d of the basic end bearing section 8 as the center. The strut 4 falls down from the first strut corbel 21 of the strut corbel 20 and the projection of the second strut corbel 22 in proper timing to put on the wale member 3 by rotating at an angle of 90 deg.. By the constitution, the strut 4 is sheltered on the wale member 3 to enable an embedded pipe to lower from above.

摘要： PROBLEM TO BE SOLVED: To improve efficiency in execution of work by a method wherein a sheathing panel is formed with jack connecting members and distance adjustment members provided at both ends of face plates attached to the surface and the reaverse side of skelton frames formed into a gridlike shape, and the panels are heaped up along a side wall of an excavated trench. SOLUTION: Skelton frames 1' and 2' are attached in a gridlike shape to a space formed by vertical beams 1 and horizontal beams 2 and face plates 3 are stuck to the surface and the reverse side of the skelton frames while jack connecting members 4, distance adjustment members 5, projected fitting members 6 and the like are provided at both ends of the face plates, and thereby an edge-equipped sheathing panel 10 is formed. The sheathing panels 10 in plural numbers are installed in heaping-up at a side wall of an excavated trench for laying potable water pipes, sewer pipes or the like therein. On installation, recessed fitting members of the sheathing panel that comes to the upper tier are fitted onto the projected fitting members 6 at both ends, and both of the panels are connected together with pins or the like inserted through pin holes 6a. The sheathing panels are heaped up similarly until they get to a specified height equivalent to the depth of the trench. Therefore, the structure is simplified for the sheathing panel while the number of component parts therefor is reduced, making manufacture and transport easy. Thereby, sheathing work can be executed efficiently.

摘要： PROBLEM TO BE SOLVED: To simplify structure and to make manufacture and execution of work easy by a method wherein channel steels or the like are fixed to both ends of a sheathing plate protecting a side wall of an excavated trench while a reinforcement member is fixed at the center, and vertical frames are formed therewith while the sheathing plates are being heaped up. SOLUTION: Channel steels each having a projected fitting part and a recessed fitting part at its upper and lower part are fixed back to back to both sides of a horizontal stiffness reinforcing member (sheathing plate) 2 made up of a beltlike steel plate or the like by bend-forming, and a reinforcement member 1' made from a channel steel is fixed at the center. The sheathing plates 2 in plural numbers are installed in heaping-up at a side wall of an excavated trench for laying portable water pipes, sewer pipes or the like therein, and thereby a sheathing panel 10 is formed. With the shathing plates 2 heaped up on installation, the projected parts and the recessed parts of the channel steels on both sides are fitted together and a vertical beam 1 is formed thereby while the reinforcement members 1' at the center are connected together to form a vertical beam. Connecting parts of the channel steels are fixed with pins or connecting metal fixtures. The structure of the sheathing plate 2 is simplified while the number of component parts are reduced, making manufacture and transport easy. Thereby, sheathing works can be executed efficiently.

摘要： PROBLEM TO BE SOLVED: To load and unload a wale bearing member from a post when to-be- embedded pipes are laid and to make it possible to freely adjust its position. SOLUTION: Post construction of sheet pile timbering is so constructed that a wale member for bearing sheet piles arranged to an interior wall of an excavated ditch in the horizontal direction is mounted to prevent the collapse of the excavated ditch. An engaging device 4a for engaging a post 1 with the side of the square wale member 3 is mounted, a pushing lever 6 forming an eccentric curved surface 7 on the front end thereof is mounted to the bottom of the wale bearing member in a turnable manner, and the engaging device 4a is engaged with the end 1a of the sheet pile post. The pushing lever 6 is brought into contact with the inside 1c of the sheet pile post, and the pushing lever is turned to push the wale bearing member against the sheet pipe post to fix. By the constitution, even in a stage where ditch excavation work is carried out, the wale bearing member is slidably fixed to a required position at all times to make it possible to carry out earth retaining work.

摘要： PROBLEM TO BE SOLVED: To obtain a field welding work device for steel pipes which efficiently executes pipe embedment work of gas and water supply pipes by making the change of roll gaps and roll movement independent. SOLUTION: There is a steering handwheel 6 for imparting a directional switching function to a front wheel 2a. A controller 9 for actuating a brake shoe 10 for the purpose of applying the brake on trucks is disposed. The brake force is applied to a rear wheel 3a by operation of a brake handle 11. Pipes are placed on the front and rear of the trucks in the upper part of a truck body and turning rolls 40a, 40b adjustable in the spacings between each other are disposed to support a steel pipe 60. The one truck is kept fixed by the brake device at the time of groove mating and welding work. The steel pipes are disposed to face each other in the state of maintaining the specified spacing therebetween by operating the initial moving device of the other one truck and are fixed by the controller 9. The work to mate the grooves of the steel pipes and the work to tack weld the steel pipes are executed by integrally moving a pair of the rolls. The welding after the tack welding work is executed while the tack welded steel pipes are rotated.
