摘要： PROBLEM TO BE SOLVED: To prepare a consistent plan by obtaining the number of division of a precast concrete block from the total weight obtained from the sectional shape and the execution length and the condition of restriction of a manufacturing equipment, and determining the schedule corresponding to the manufacturing cycle. SOLUTION: A preparing equipment 10 comprises a CPU 10b to be connected through a bus line 10a, a keyboard switch 10c, a display 10d, a printer 10e, a ROM 10f to store the processing procedure, and a RAM 10g. The same symbol is attached to water feeding/discharging ducts installed in a nuclear power station, etc., of the same shape. The dimensions of the sectional shape and the extension of the execution are inputted, and the sectional area of each duct, the unit weight of each duct, and the total block numbers by the weight class are successively operated while making correction as necessary. Then, the frequency for using the molds, the number of necessary molds are obtained, and the manufacturing period for each duct is obtained to determine the manufacturing schedule. The consistent manufacturing plan can be planned, and simply and rapidly corrected in the case of the review.

摘要： PROBLEM TO BE SOLVED: To make out a consistent plan. SOLUTION: A manufacturing of longer structure and installation work planning device is so constituted that when a procedure is started, an initial setting is made in S1, sectional area SA1 -SAn every duct A1-An is calculated in S2, and unit weight wA1 -wAn every duct A1-An is calculated from an obtained sectional area in the successive S3. In the successive S4, gross weight WAn every duct A1-An is calculated with a formula SAn ×LAN×wAn . Partition function every duct A1-An is obtained with a formula WAn ÷Wo in S5, and temporary article number BN'An of block corresponding to partition are calculated. Temporary length BL'An of the partitioned block is obtained with LAn ÷N'An in S6, and temporary weight BW'An of the block is calculated with BL'An ×wAn in S7. Temporary weight BW'An is totalled by weight class in S8, it is indicated as total number of temporary block, and the necessity of correction is decided in the successive step. Then, based on an installation work plan of the duct set in advance, and based on the number of blocks and manufacturing cycle set in advance, a block manufacturing plan for making a specific period prior to the completion of the installation work plan as the termination is determined.

摘要： PROBLEM TO BE SOLVED: To provide an air- and water-tight protecting method of a concrete conduit for a power cable or a communication cable laid in a common-use cable tunnel. SOLUTION: A concrete conduit in a common-use cable tunnel has a plurality of conduit holes for pausing cables. A polyethylene tube 2 with each trumpet- shaped hook member 3 on both ends is embedded in each conduit hole in a way that a linear hook part 4 of the trumpet-shaped hook member 3 is made flush with an end face 1a of the conduit. Then, a porous face of the porous concrete conduit is sealed, and an annular gasket 5 is bonded to the linear hook part 4. When a next concrete conduit is connected, the annular gasket 5 is deformed tightly under pressure to seal the inside from the outside of the connected conduits.

摘要： PROBLEM TO BE SOLVED: To increase strength and to increase a tensile strength to the member to be fixed mounting side by a method wherein an insert element body embedded in a structure is formed in the shape of a barrel the outer peripheral surface of which forms a curved surface and a notch being a detent is formed in an end part. SOLUTION: An insert element body 7 in the shape of a barrel having a curved surface-form outer periphery is formed such that an axial screw hole 7a for fixing is formed at a central part in a radial direction, a detent notch 7b is formed in one end, and the outside diameter of the other end is reduced to a value lower than that of 7c. The insert element body 7 is embedded such that a cylinder body 9 having a fixing tool insertion hole 9a formed in an inner periphery is located between the surface of the structure 8 and the insert element body and the small part side forms the surface side of the structure 8. A fixing tool 10 is inserted in a member 6 to be fixed and the fixing tool insertion hole 9a and a coupling part 10a is joined in a screwed-in state with a hole 7a for fixing of the insert element body 7 and the member 6 to be fixed is attached to the structure 8. By forming the insert element 7 in the shape of a barrel, strength is increased and further the tensile strength of the insert element body 7, embedded in the structure 8, to the member to be fixed mounting side is increased.

摘要： PROBLEM TO BE SOLVED: To prevent fissure, crack and deterioration and to prevent the damage of an inserted cable by applying a permeable concrete strengthening agent of a water glass system on the concrete surface of a precast concrete perforated pipe. SOLUTION: If the outside surface of the perforated pipe is in a gritty state, the chemical materials included in rainwater and ground water are liable to penetrate such pipe and the deterioration of the pipe is worried. If the inside surface of the pipe is in the gritty state, the danger of damaging the cable at the time of insertion is high. An aq. soln. of sodium silicate expressed by Na2 O.nSiO2 (n is 2 to 4) is used as the chief material of the strengthening agent. This agent permeates the concrete and reacts with the calcium compd., aluminum compd., etc., in the concrete to form glass-like cured matter, thereby filling the gaps among the pores on the surface, making the surface structure denser and smoother and increasing its strength. While a method of applying the agent by immersing the pipe for specified time in a strengthening agent bath is simple and sure, the application of the agent on the inside and out of the pipe by the procedure for spray coating is equally well.

摘要： PROBLEM TO BE SOLVED: To make it possible to prevent the generation of cracks or voids by leaving a peripheral edge slightly on the rear surface of a PC board and constructing a concrete product construction foundation PC board on which a normal temperature hardened elastic body is laminated, on a crushed stone layer and forcing the board to follow an uneven surface. SOLUTION: A polyurethane-based normal temperature hardened elastic body 2 is laminated on the whole surface with an uniform thickness except for a peripheral edge which is slightly left over on one surface of a PC board which forms a joint comprising a projected part 3 and recessed part 4 on the end in the longitudinal direction, thereby forming a foundation PC board. The foundation PC boards are constructed on the crushed stone layer consolidated on an excavated ground with the normal temperature hardened elastic body 2 placed downward while they are being jointed with the uneven joint of the PC board. The normal temperature hardened elastic body 2 follows with the uneven or undulated areas on the crushed stone and buries the cavity, thereby supporting the layer PC boards elastically. At that time, the normal temperature hardened elastic body 2, while being subjected to deformation, is pushed and extended toward the peripheral edge but it is not extended to the outside of the peripheral edge. This construction makes it possible to lay concrete products on the top of the PC boards lined up horizontally.

摘要： PURPOSE: To provide a method to mold a PC pipe using a centrifugal molding process by which it is possible to mold easily the PC pipe with an uneven pattern, on the surface, such as a stacked stone pattern or a chipped pattern. CONSTITUTION: When molding a PC pipe using a PC pipe molding form 4, an uneven pattern molding mat 5 for molding an uneven pattern on the surface of the PC pipe is caused to adhere to the internal surface of the PC pipe molding form 4. Further, a separating agent and an adhesive material are sprayed sequentially over the internal surface of the uneven pattern molding mat 5. Next, decorative powder of a specified thickness is sprayed over the inner surface of the adhesive material to form an uneven pattern layer 2. In addition, concrete is placed inside of the uneven pattern layer 2.
