摘要： PROBLEM TO BE SOLVED: To provide a U-groove block for not generating a shaking noise by an automobile or the like running on a cover plate block by eliminating an independent distortion between a body block and the cover plate block and a method for molding the same. SOLUTION: A method for molding the U-groove block having one set of the body blocks 10 and the cover plate block 20 comprises the steps of previously molding the one block, and curing to harden the block. The method further comprises the steps of filling a ready mixed concrete 20 partly in its molding form in order to mold the another block, and separably placing joint molding both the blocks.

摘要： PURPOSE:To improve the curing efficiency, save energy and secure the required strength by forming a part or a front section of a site of a mold being in contact with concrete in the form of a double structure and feeding a heat developing substance or a heating medium as the minimum required in compliance with the thickness and volume of respective sites of a product into a space. CONSTITUTION:For example, a mold of block 1 for a U-shaped side gutter is divided into, for example, mold sections 2, 12, 4 and 3 formed by dividing the outer side face and the inner peripheral face of a standing section into two, upper and lower respectively, and a mold section 5 of the lower face of a bottom wall section, and the divided sections are formed into a double structure provided with hollow sections 11 respectively. Heating medium injection openings 13 and discharge openings 14 are formed on respective mold sections 2-5 and 12 to feed the heating medium. For supplying the heat for accelerating curing, the method of filling the spaces 11 with a heat developing material (agent), the method of flowing the heating medium such as high pressure vapor, or hot air, hot water or oil or making the same remaining in, the method of filling water, oil or the like and heating by electric heat or the like can be applied selectively and properly. The curing temperature is adjusted in compliance with the thickness and volume of respective sites.

摘要： PURPOSE:To obtain a composite function type gutter, in which initial polluted water is drained quickly, an outflow inhibiting function is controlled and improved, a storage space is ensured and a function recovery measure at the time of clogging is taken simply and which has a water control and intake function and a storage infiltration function. CONSTITUTION:A water control and intake post body 7, which is formed in an upper section closed type or a cover type and in which the whole surface is opened or a part is opened in a lower section and a plurality of intakes 9 are formed to a top section 8 projected near a center, is installed to the upper section of the sidewall of a gutter body 1, and the internal space of a gutter is divided into an upper drainage ditch 18 and a lower drainage ditch 19 by a bottom block 15 mounted to the intermediate section of the sidewall. Exchangeable filters 20a, 20b, 21 for preventing clogging are set up to the intakes 9 of the water control and intake post body 7, and an exchangeable sheet 22 for obviating clogging is laid on the opening section 5 of the bottom of the gutter.

摘要： PURPOSE:To prevent the intrusion of water to a transmission line as well as to cut down the cost of construction and maintenance by a method in which a water-passing hole and a housing hole for a transmission line are provided and a water-stop sealing member is provided between the connected ends. CONSTITUTION:Water-passing holes 2 and 3 with or without an opening on the ground's surface and a housing hole 4 for a transmission line of energy, information, etc., are provided for a composite functional pipeline 1. A water- stop seal 44 is also provided between the connected ends 1c and 1d. The pipeline 1 is set in an excavated trench, a desired transmission line is inserted into the hole 4, and a given number of the pipelines 1 are connected with each other. Soil is then back-filled in the surrounding of the pipelines 1, 1.

摘要： PURPOSE:To manufacture a concrete-steel pipe composite pile having a high strength and an uniform inside diameter and enabling auger machine to be used properly without any trouble by a small-size manufacturing apparatus in which an expandible concrete is packed into the inner and outer pipes of a double steel pipe, consolidated and hardened. CONSTITUTION:The one end opening of concentrically set inner and outer steel pipes 1 and 2 is closed by a ringed end wall plate 4, concrete 3 is packed into the steel pipes 1 and 2, and the other end opening is closed by a ringed end wall plate 4. Since the pile has an uniform inside diameter, an auger machine can be used properly without any trouble. Also, since the pile has a high strength, the size of the diameter can be reduced and also the pile can be driven by a small driving force.

摘要： PURPOSE:To obtain a concrete-steel pipe composite pile having a high strength by a method in which cylindrical pieces having small holes through which a PC steel material are pierced are fitted on the outside of a steel pipe, a grout is injected into the aperture between the cylindrical pieces and the steel pipe, and then a prestress is applied through the PC steel material. CONSTITUTION:A large number of concrete cylindrical pieces 2 are fitted on the outside of a steel pipe 1, PC steel materials 6 are pierced through small holes 5 axially formed in the cylindrical pieces 2, and a grout is injected into the aperture between the steel pipe and the cylindrical pieces and between the cylindrical pieces. Then, a prestress is applied through the PC steel materials whose both ends are fixed to the steel pipe 1. By this, a composite pile having a high strength can be obtained because the steel pile 1 is integrately and pressingly combined with the concrete cylindrical pieces 2.
