摘要： PROBLEM TO BE SOLVED: To construct a parking space pit being square in plan with ease during the short period of time by laying side by side precast concrete U-shaped blocks being equal to the width of an underground space, and closing its opened faces with end plate blocks. SOLUTION: U-shaped blocks 2 are manufactured by precast concrete, which is laterally elongated and having the distance of sidewall 2a rising at both ends being equal to one width of a pit 1. The one rising sidewall 2a is made higher slightly, and holes of a safety fence are made on the upper surface, furthermore, a drainage gutter 2 is formed at the inside of a corner part with a bottom plate 2b, and a drainage pump pit 6 is formed every required number of the U-shaped blocks 2. A pit 1 is excavated, and after constructing a foundation at the bottom part, U-shaped blocks 2 are juxtaposed; then connecting recessed parts 7 at end parts by bolts by interposing water prevention rubber between the connection surfaces. The opened faces are closed by a end plate block 3, and a safety fence is secured in the holes 4. Thus, a pit for parking space can be constructed even in a limited area in a short construction period of time by excavating only for the width of the pit 1, and disposing only U-shaped blocks 2 and end plate blocks 3 in the inner part.

摘要： PROBLEM TO BE SOLVED: To provide a corrosion protective method of a tension anchor body for a steel product for prestressed concrete used for a common cable (C.C. box culvert), a bridge beam, and the like. SOLUTION: In this corrosion protective method of a tension anchor body for a steel product for prestressed concrete, a protective cap 6 made of plastic and slightly larger than a tension anchor body 5 is fitted to the tension anchor body 5 for clipping a steel product for prestressed concrete protruded from the end of a specified precast concrete construction, and then resin adhesive material 9 is filled from a filling hole 7 provided at the tip of the protective cap 6. Filling is stopped upon confirming that the resin adhesive filled in a clearance part 10 formed between the tension anchor body 5 and the protective cap 6 overflows out of an air vent hole 8 provided at the base end part of the protective cap 6. Corrosion protection of the whole area of the tension anchor body 5 including a steel end part is performed by outside air cutoff of this resin adhesive material 9.

摘要： PROBLEM TO BE SOLVED: To provide a junction structure for segments in which generation of excessive stress can be prevented when a large bend moment is applied to a segment junction part, and in which assemblage precision and water stopping performance are excellent in a shield tunnel lining body comprising plural segments of concrete assembled in circumferential and axial directions by prestress introduced for integrating them with each other. SOLUTION: A protruded part 11 of a trapezoid-shaped cross sectional surface is provided on an end surface of a segment 1a to be jointed with another segment 1b. On an end surface of the segment 1b to be jointed with the segment 1a, a recessed part 12 is provided in which the protruded part 11 is contained having a gap between them. In the gap, a seal member 13 comprising elastic material or viscoelastic material and compression-deformed to the width of the gap is inserted. For the seal member 13, water-swollen rubber is used, favorably, and it is applied to the end surface of one segment before jointing both segments with each other.

摘要： PROBLEM TO BE SOLVED: To make it possible to prepare a consistent schedule and estimate a manufacturing factory. SOLUTION: When a procedure is started, initialization is executed, the cross-sectional area of each duct is calculated and each duct unit weight is calculated from the cross-sectional area. Next the total weight W of each duct is obtained to obtain the temporary number of blocks corresponding to division. After then, the number of necessary molding flasks is calculated at s19 and based on the installing constructing schedule of a previously set duct, and based on the number of blocks and a previously set manufacturing cycle, the manufacturing schedule of the block whose finish time is previously period before the completion of an installing constructing schedule at s21. At a continual s22, the day manufacturing quantity of the block is calculated and smoothed and after then the arrangement of optimum molding flask on a bed of each manufacturing day is decided based on the smoothed day manufacturing quantity, the kind and the number of molding frames to use the present day and the dimension of a bed. Then the necessary and maximum number of the beds are estimated by the arrangement of optimum molding flasks.
