摘要： PURPOSE:To prevent discoloration of the surface of the concrete, which is placed before, to be caused by flow-down of the moisture at the time of placing concrete with permeable form. CONSTITUTION:A form 10 is provided with an upper and a lower form plates 12, 14 and permeable materials 16, 18, which are attached to the concrete placement side of each form plate 12, 14. Each form plate 12, 14 has a height corresponding to the height of one time placement of concrete. The permeable materials 16, 18 attached to each form plate 12, 14 are folded at the ends of the form plates 12, 14 so that ends of the permeable materials 16, 18 are pinched by the upper and the lower form plates 12, 14. An impermeable sheet 20 is interposed between the ends of the permeable materials 16, 18, which are pinched by the upper and the lower form plates 12, 14.

摘要： PROBLEM TO BE SOLVED: To realize omission of processing of placing joint. SOLUTION: According to the method for placing joint, a pre-cast concrete layer 10 is placed, and after hardening of the pre-cast concrete layer 10, a post-cast concrete layer 12 is placed on an upper side of the pre-cast concrete layer 10. At the time of placing the pre-cast concrete layer 10, when placed concrete reaches a location proximate to a joint portion 14, reinforcing short fibers 16 against shearing are mixed in the concrete. The short fibers 16 are cut to the length of about 2 to 6 cm. The mixing ratio of the short fibers 16 to concrete is set, e.g. in the range of 0.5 to 1.5% by voluminal ratio.

摘要： PROBLEM TO BE SOLVED: To prevent propagation to an imitation rock material of a crack even when the crack occurs in a hydraulic material by forming an easily deformable flexible layer between the hydraulic material and an imitation rock. SOLUTION: In the method, an imitation rock material 10 is installed beforehand at a specified place before the construction of a concrete structure. A flexible layer 12 is formed on the rear side of the imitation rock material 10. The flexible layer 12 has waterproofness and deformation following properties as seen in urethane, asphalt, etc., and is applied on an imitation rock factory and an execution field. When the imitation rock material 10 is assembled, steel materials 14 for a timbering are mounted on the rear side of the imitation rock material 10, anchor materials 16 are set up among the imitation rock material 10 and the steel materials 14, and the imitation rock material 10 is supported. When the assembly and installation of the imitation rock material 10 are completed, concrete C for forming the new concrete structure is placed on the rear side of the imitation rock material 10. When placed concrete C is cured, the concrete structure is built while the imitation rock material 10 unified on the surface side of the concrete structure is mounted.

摘要： PROBLEM TO BE SOLVED: To prevent cracks on a form by providing a deformation absorbing layer such as a rubber sheet on the back side of a precast concrete form becoming a product as it is, and absorbing the relative deformation of placed concrete. SOLUTION: A form 1 for forming a wall, a beam, a column, a ceiling, or a floor is manufactured with reinforced concrete, prestressed concrete, or fiber-reinforced concrete at a factory, and a deformation absorbing layer 4 such as a rubber sheet is provided on its back side. The sheet-like deformation absorbing layer 4 may be stuck, or an elastic film may be formed by spraying or coating. When a relative change is generated between concrete and the form 1 due to thermal expansion characteristics, drying shrinkage property, and temperature distribution after concrete is placed into the form 1, the change is absorbed by the deformation absorbing layer 4. The cracking of the form 1 is prevented, and the generation of gaps between the form 1 and concrete can be prevented.

摘要： PROBLEM TO BE SOLVED: To prevent such troubles that the inside is dried if no repairing material is placed immediately after the erection of a form, a puddle is easily generated on the inner face (upper face) of the form, material peeling may occur, the drained treatment for the draining work is troublesome, and the construction cost for man-hours and material cost is increased. SOLUTION: A form 2 is arranged below a chipped face 1a. A humidification port 10 penetrating the form 2 is opened on the lower face of the form 2, multiple bleeder ports 12 are opened at proper intervals around the humidification port 10, and the inside and outside of the form 2 are communicated. An ultrasonic humidifier 14 is arranged below the humidification port 10. The ultrasonic humidifier 14 is connected to the humidification port 10 via the hose joint 16a of a bellows type hose 16 extended from its discharge port 14a. When water mist is fed into the form 2 by the drive of the ultrasonic humidifier 14 after its connection, water mist is stuck to the chipped face 1a in the form 1 to wet it.

CONSTITUTION: The bottom of a concrete building frame 10 is chipped (a), and an anchorage member 14 is driven almost perpendicularly into the bottom of the concrete building frame 10. Then, a grid 22 is stretched, opposite to the entire face of the chipped surface 12, and a hexagonal nut 18 with a vane member 16 fixed in parallel therewith is screwed into the projecting part of the anchorage member 14 and a wood-concrete beam 20 is screwed (b) onto the lower end of the anchorage member 14. After that a form 24 is erected, being in contact with the underside of the wood-concrete beam 20. After the form 24 is erected, a repairing material 30 such as concrete or mortar is placed (c) into a space between the form 24 and the chipped surface 12. After hardening of the repairing material 30, the form 24 is removed and the wood-concrete beam 20 is removed after the surplus length of the anchorage member 14 is cut, and an appropriate surface treatment is applied.

摘要： PROBLEM TO BE SOLVED: To provide an operation control device for a dust collector which can efficiently and economically operate the dust collector that is for use in civil engineering work including specific work steps in which dust generation is expected. SOLUTION: At the execution of a tunnel excavation work, when the specific work steps in which dust generation is expected including "a blasting step", "a muck removing step", "a spotting step", and "a spraying step" are started, a blasting step detecting sensor 3, a muck removing step detecting sensor 4, a spotting step detecting sensor 5, and a spraying step detecting sensor 6 output respective detecting signals corresponding to the steps, and the control device 2 controls the dust collector 1 according to the detected signal. In the steps other than the steps in which dust generation is expected, the specific work step detecting sensors halt the outputting of the detecting signals, and therefore the control device 2 sets the dust collector 1 in a quiescent mode or a slow-operating mode.

摘要： PURPOSE:To provide a muddy water treatment system which surely prevents water pollution of a river. CONSTITUTION:In a muddy water treatment system in which muddy water generated in water utilization facility 1 is treated and the treated water 4 is discharged to a river 3 through a discharge channel 7, the water quality of water 4 before discharge is measured with a treated water quality measuring instrument 16, the values of water quality upstream 3a and downstream 3c from the channel 7 in the river 3 are measured with river water quality measuring instruments 12a, 12c. The water quality signals of the instruments 16, 12a, 12c are converted into the water quality signals of a standard unit system by a programmable logic controller 10 to be stored in a memory 9, the water quality signals in the memory 9 are monitored by a controller 4, and the channel 7 is opened to discharge the water 4 when the water quality is within a specified drainage standard. The upstream water quality and the downstream water quality in the memory 9 are monitored when the channel 7 is opened, and the channel 7 is closed when the difference between the upstream water quality and the downstream water quality becomes a specified tolerance value or more.
