摘要： PURPOSE:To raise the slippery function of a foundation pile by forming a protective layer of polyurethane resin containing an inorganic filler having a given linear expansion coefficient on the outside of a slip layer of visco-elastic substance on a pile. CONSTITUTION:A slip layer 2 of a visco-elastic substance is formed on the periphery of a foundation pile 1, e.g., steel tubular pile, H-steel pile, etc., for relieving negative frictional forces, which is to be used is soft ground. A protective layer 3 of polyurethane resin prepared from reaction of a compound with two or ore hydroxyl groups and a compound with two or more isocyanate groups, containing 5-200wt% an inorganic filler having a linear expansion coefficient of 0.1X10 / deg.C or less, is formed on the surface of the layer 2. The occurrence of deformation, cracking, delamination, and blistering, etc., of the protective layer 3 can thus be prevented.

摘要： PURPOSE:To accurately measure the quantity of a difference in the outer surface level of a weld by a simple instrument by detecting the quantity of the displacement in the horizontal direction orthogonally intersecting the direction of the pipe axis of an object to be measured and the quantity of the rotation of the object in a circumferential direction and correcting differences in the values of detected distances in accordance with both of the quantities. CONSTITUTION:Distance detectors D1 and D2 are arranged above a pipe P and on both sides of a feed center line CL with suitable distances therefrom. Distance detectors D3 and D4 are arranged on both the sides of the pipe P and the line CL with suitable distances between the line CL and the detectors D3 and D4. All the detectors detect the distances between the outer surface of the pipe P and the detectors. When the profile of the outer surface near the weld of the pipe P is approximated by, for example, the accompanying elliptic expression I, the level differences Ys1 and Ys2 produced by the lateral displacement and the rotation of the pipe, respectively, are given by a solution Ys1=[(Bl1-C)+{(bl1+C) -4A(Dl1 -El1+ F} ]/2A and another solution. When the pipe is laterally displaced and rotated and the values of the distances detected by the distance detectors D1 and D2 are L1a and L2a, respec tively, the quantity dW1 of the difference in the outer surface level of the weld corrected in accordance with the lateral displacement quantity dh and the circumferential rotational quantity dQ is obtained from the accompanying expression II.

摘要： PURPOSE:To measure the quantity of a difference in the outer surface level of a weld on-line by a simple instrument by detecting the quantities of displacement in a horizontal direction and of rotation in a circumferential direction and, in accordance with both of the quantities, correcting differences in the detected values of circumferential distances using the equation of an outer surface profile obtained from the group of the detected values of the distances in the circumferential direction. CONSTITUTION:Equations Y=FL(x), Y=FR(x) indicative of the profiles of outer surfaces in a circumferential direction on both sides of a weld are obtained from the group of the values of detected distances by displacing a distance detector D1 or D2 with a suitable step in a horizontal direction orthogonally intersecting the direction of the axis of a pipe P. Then, a coordinate transformation is applied to the equations of X and Y at a given measuring time in accordance with a horizontal displacement quantity dh and a rotational quantity dQ to be changed to Ya=FL(Xa) and Ya=Fa(Xa), respectively. When the X coordinates (l1, L2) of the measuring points S1a and S2a on the outer surface of the pipe in an X-Y coordinate system are transformed to l1a and l2a, respectively, in an Xa-Ya coordinate system, the quantity dWa of the difference in the outer surface level of the weld that is corrected in accordance with the displacement and rotational quantities dh and dQ, respectively, can be obtained by an accompanying expression, where L1a and L2a are the values of detected distances at the measuring points S1a and S2a, respectively.

摘要： PURPOSE:To easily form a corrosion-resistant layer on the periphery of a steel tubular pile even on construction site by a method in which a tape having a hot- bonding adhesive layer on its one side is spirally wound in a partly lapped state on the periphery of a steel tubular pile preheated. CONSTITUTION:A heat-shrinkable polyolefin tape 1, having a adhesive layer 2 composed of a hot-bonding polyolefin with adhesive functional groups on its one side, is spirally wound in a partly lapped state on the periphery of a steel tubular pile 4 preheated, whereupon the adhesive layer 2 between the pile 4 and the tape 1 is thermally joined with the adhesive layer 2 in the lapped portion of the tape 1. A high-strength and high-performance anticorrosive layer can thus be obtained on the periphery of the pile.

摘要： PURPOSE:To produce steel having superior corrosion resistance and sulfide corrosion cracking resistance by subjecting low alloy steel contg. C, Si, Mn, Co to a high temp. oxidation treatment and forming a Co-enriched layer at the boundary between oxide scale and steel base. CONSTITUTION:The product produced from the molten steel contg. 0.05-0.50% C, 0.05-1.00% Si, 0.10-2.00% Mn, and 0.03-0.55% Co by wt%, and consisting of the balance Fe and unavoidable impurities or the product consisting in applying a heat treatment to this product is subjected to a high temp. oxidation treatment. Then, a layer enriched of the concn. of Co at a number of times the content of Co is formed at the boundary between oxide scale and steel base. The Co-enriched layer acts as a protecting film which prevents the entry of the hydrogen produced by corrosion into the steel in a wet environment contg. H2S and prevents the occurrence and propagation of sulfide corrosion cracking.

摘要： PURPOSE:To provide a high tensile steel with superior yield strength and superior sulfide corrosion crack resistance by subjecting steel contg. Mn and Co or further contg. special added elements to hardening and tempering. CONSTITUTION:To steel contg. 0.05-0.50% C and 0.10-1.0% Si are added 0.1-2.0% Mn for enhancing the hardenability, strength and toughness of the steel and 0.05-1.50% Co as an element for enhancing the sulfide corrosion crack resistance and corrosion resistance of the steel. To the steel may further be added 0.10- 0.50% Cu, 0.20-2.0% Cr, 0.05-1.0% Mo, 0.05-1.0% W, 0.01-0.15% Nb, 0.01-0.15% V, 0.01-0.15% Ti and 0.0003-0.0050% B. The resulting high tensile steel is used to construct the weld zones of an oil well pipe, a line pipe or an LPG tank, and by subjecting the zones to perfect hardening and sufficient tempering, a tempered martensite structure is formed to impart >=60kg/mm. yield strength and superior sulfide corrosion crack resistance.

摘要： PROBLEM TO BE SOLVED: To improve the working property of measurement by providing an optical wave range finder on a clamp attachably and detachably mounted within a steel pipe pile, and measuring the height of the pipe earth at the time of penetrating the pipe into the ground. SOLUTION: A clamp 3 attachably and detachably mounted within an open end steel pipe pile 1 has an optical wave range finder 4 to measure the height (h) of the pipe earth 2 intruding into the pile 1 in no contact. The position of the range finder 4 is set within a limit distance related to the clamp set error and the beam characteristic so that an optical wave beam 5 never interferes with the inner wall of the pile 1. When an open end steel pipe pile having a blade on the lower end outer surface thereof is rotated and pressed into the ground, the range finder 4 is provided on the pile in the same manner, and the pipe earth height measurement data is radio transmitted from a transmitter provided at the top of the pile to a receiver on the ground to measure the height of the pipe earth intruding into the pipe in no contact in the penetration of the pile to the ground. According to this, the measurement can be safely performed without interrupting the penetrating work of the pile, and the tip support force of the pile can be precisely evaluated.
