摘要： PURPOSE:To strengthen the repair of piles of a pier and the like by a method wherein annular concrete blocks are deposited fitting outerward at outer peripheries of eroded steel pipe piles, the upper block and the lower block are connected by a steel bar, and concrete is placed in between the block and the pile. CONSTITUTION:At the submerged part of a steel pipe pile 2 scarcely eroded, a plate 13 is placed to the periphety of a steel pipe 2 and the plate 13 is fixed by an inner wedge 11 and an outer wedge 12. Next, annular concrete blocks 16 fitted outward into the pile 2 are stacked successively onto the plate 13 to surround the eroded part of the pile. Then, the concrete block 16 is connected in the vertical direction by steel bars 10 and concrete is placed between the block 16 and the pile 2. Consequently, the pile 2 supporting the pier can be firmly repaired.

摘要： PURPOSE:To form a working space for steel tube struts below the water surface in a short time by a method in which vertically split bodies are connected in an opening and closing manner to form a partition wall, and a float is attached to the periphery of the partition wall in such a way as to enable the partition wall to be towed over the water surface. CONSTITUTION:Vertically split bodies 20a and 20b are connected with a hinge 21 in an opening and closing manner to form a partition wall body 20, in which the other separated portion is designed to be fixed by a connector 22. A float 25 is attached to the periphery of the wall body 20. The reinforcing operation device is floated, transported, and set on the periphery of a steel tubular strut 3 under water while regulating the buoyancy of the flat 25, and the strut 3 and the wall body 20 are fixed by a jack 28. Water-stopping operation is also made by a packing tube 23. Water is discharged from the wall body 20, and a corrosion-preventing cover is formed on the strut 3.

摘要： PURPOSE:To make repairing work easier by drying the surface of a revetment by a method in which a casing whose upside and one side are opened is settled along the revement, the lower anchor plate of the casing is penetrated into the ground, and water in the casing is drained. CONSTITUTION:To dry up the portion under water of a revement for repairing a sheet pile 1 for revetment, water is first charged into the tank 6 of a drainage structure and a casing 2 is settled along the sheet pile 1. When the anchor plate 11 reaches the bottom under water, jet water is jetted through a jet nozzle 18 to penetrate the plate 11 into the ground. Water in the casing 2 is drained by an underwater pump 12, and when the difference in water level between the inside and the outside becomes about 50cm, an air bag 14 below the lattice 5 is inflated to stop the flow of water. After water is completely drained from the casing 2, sheet pile 1 is repaired.

摘要： PURPOSE:To repair existing long pipes by a method in which plural new pipes are penetrated into an existing pipeline from a vertical pit by means of an end- press jack until a given length of the pipes are penetrated, and the new pipes are further penetrated by means of a mid-press jack. CONSTITUTION:New pipes 17a and 17b are orderly inserted into a superannuated existing pipeline 11 by means of an end-press jack 15. When a limit strength to withstand the pressure of the pipe is reached, a mid-press oil-pressure jack 20 is interposed between the new pipes 17e and 18a, and the new pipes 17 and 18 are further penetrated by repeated operations of the jacks 15 and 20. When the top pipe 17a reaches the forward vertical pit 13, the jack 20 is removed out and the new pipe 18 is advanced to complete the construction work.
