摘要： PURPOSE:To raise the corrosion resistance of steel materials for civil construction work as well as to protect the anticorrosive film formed on the surface of steel materials from damage during handling and driving operations by integrally forming a heavily anticorrosive film of urethane elastomer on the surface of the steel materials, e.g. steel pipe, etc., to be driven. CONSTITUTION:Anticorrosive covering film 18 of urethane elastomer, having excellent corrosion resistance, excellent impact resistance, and excellent wear resistance, is integrally provided through a primer on both sides of the surface of a steel tubular sheet pile consisting of a steel tube 1 and partly notched round steel couplers 2 to be fixed to both sides in the diametrical direction of the steel tube 1. The urethane elastomer used is prepared by mixing an isocyanate and a polyol. Damage to the paint film can thus be prevented during the driving operations, and the corrosion resistance of the sheet pile can be kept for long period of time.

摘要： PURPOSE:To provide the titled steel sheet pile covered with coating film which is not marred by handling and driving operation and retains corrosion resistance over a long period, prepared by applying a heavy-duty corrosion preventive coating which contains coating film reinforcing material on one or both sides of steel sheet pile. CONSTITUTION:A heavy-duty corrosion preventive coating with excellent scratch and corrosion resistance is prepared by adding 10-1,000pts.vol. coating film reinforcing material selected from among glass flake, silica sand and BaSO4 to 100pts.vol. epoxy or polyester resin coating. Linear, U-shaped or Z-shaped steel pile 1 is blasted with shot, grid or sand on the surface except fitting groove 2 to the Swedish Standard SIS-Sa 2.1/2 or higher and is then coated with the above coating in the thickness of 500-5,000mu, followed by drying for formation of heavy-duty rustproof coating film 5.

摘要： PURPOSE:To prevent occurrence of uncoated portion by breaking the bubbles to form finely splashed coating material by a method wherein a swelling coating material is mixed with bubbles of compressed air and ejected from a nozzle. CONSTITUTION:Swelling coating material is sent to a nozzle 3 via pipe 8 by the pressure of compressed air in the upper part of tank 2 which is sent from a compressor. During this transfer, compressed air enters from hole 9 located at undipped zone and is mixed as bubble 10. Mixing of air bubble 10 increases the flow rate of liquid in flexible pipe 11 and the fricational loss is reduced. The swelling coating material including bubbles 10 of compressed air passes through a flexible pipe 11 and reaches to the nozzle 3. The coating material 1 ejected from the nozzle 3 causes, at ejection, the breakage of bubbles contg. compressed air into fine splashes so that they are sprayed on the entire internal surface of paws of steel sheet pile 6. As a result, occurrence of uncoated portion is prevented.

摘要： PURPOSE:To reinforce a portion in the vicinity of the corrosion part of a steel pipe pile by means of a corrosion proof part, by a method wherein a position, where the corrosion part of the steel pipe pile is present, is surrounded with a split cylindrical reinforcing body made of steel, and forms are additionally installed to fill a space between the forms and the steel pipe pile with a curable filling material. CONSTITUTION:A split cylindrical reinforcing body 1 made of steel is formed such that a number of semicircular reinforcing bars 10 are vertically arranged at intervals, and the reinforcing bars 10 and longitudinal reinforcing bars 11 are secured to each other by welding and the like. The reinforcing body 1 is located so that it surrounds a position where a corrosion part 3 in a steel pipe pile 2 is present to form a cylindrical reinforcing body 4. After forms 5 surrounding the cylindrical reinforcing body 4 are arranged, a space between the forms 5 and the steel pipe pile 2 is filled with a curable filling material 6. This enables easy and rapid installation of a structure for reinforcing the corrosion part through reduction in a work in water, and permits a sharp decrease in a cost.

摘要： PURPOSE:To perform a repairing work which is reduced in a work in water, by a method wherein division type bands, in which dowels are previously filled, are secured to the upper and the lower part of the corrosion part of a steel pipe pile, and reinforcing bars and forms are installed to the outer peripheries of the bands between the two bands to place concrete. CONSTITUTION:Repair of a steel pipe pile 4 in which a hole 5 is caused by corrosion is such that division type bands 1, in which dowels 2 are previously filled, are secured to the upper and the lower part of the hole 5 by tightening bolts 10, and reinforcing bars 14 and 15 are arranged on the outer periphery of the two bands 1. Further, after forms 7 and 12 are installed to the outer periphery and the lower end part of the reinforcing bars, a curable filling material 8, such as concrete, is placed between the forms 7, 12 and the steel pipe pile 4, and after the curable filling material 8 is cured, the forms 7 and 12 are removed to complete a work. This eliminates welding of the dowels 2 in water, resulting in the decrease in performing repair work in water.
