摘要： PURPOSE:To reduce the construction period and the construction cost by throwing banking materials on a reinforcing sheet in one end of which sandbags are wrapped, to construct a banking body, thereafter mounting forms along the slope by means of spacer-rods capable of being expanded and contracted to construct a retaining wall. CONSTITUTION:Banking materials 3 are thrown on a water-permeable reinforcing sheet 2 such as geo-textile, etc., in one end of which sandbags 1 are wrapped, up to the same height as that of the sandbags 1. In this case, the upper stage of a banking is shifted inward from the lower stage to repeat the operations in sequence to pile up the banking body. After construction of the banking body, the end parts of the reinforcing sheet 2 are pinched by steel plates of the end parts of spacer-rods 4 to be connected to the slope of the banking body. Then, the spacer-rods 4 are expanded and contracted to position forms 6 along the slope at fixed intervals, and between the formes and the slope concrete 71. is placed to construct a retaining wall 7. The concrete placing pressure can thus be applied to the banking body, and thereby the retaining wall 7 can be positively constructed.

摘要： PURPOSE:To simplify building operations of a banking and improve drainage capacity in the banking by laying a reinforcing sheet on one end of a water- permeable slope forming frame, and charging drainage materials and banking materials to form laminated plural layers. CONSTITUTION:A slope frame 11 to which water permeable wire nettings 14 are fixed and a ground contact frame 12 are joined and reinforced with an angle steel to manufacture a slope forming frame 1. Then the end part of a strong and water-permeable reinforcing sheet 2 such as geo-textile, etc., is fixed to the ground contact frame 12. Next a water-permeable sheet 3 is put over the slope frame 11 and the lower part of the sheet is overlapped with the reinforcing sheet 2. Further, drainage materials 4 are charged inside the slope forming frame 1 and wrapped with the upper part of the water-permeable sheet 3 not to drop down from the wire nettings. Banking materials 5 are charged in the area except the area where the drainage materials are charged, and thereafter the above operations are repeated to form a laminated banking body 5. Thus, the operating efficiency of building up banking, and drainage in the banking can be improved.

摘要： PURPOSE:To shorten the construction period by driving an anchor bolt into the face of slope of natural ground, mounting a spacer-hardware capable of expanding and contracting in the axial direction of the bolt to the bolt end exposed from the face of slope, and mounting a form to the free end of the spacer-hardware at a certain distance away from the face of slope to place concrete. CONSTITUTION:An anchor bolt 2 is driven into the face of slope of natural ground, and a spacer-hardware 1 formed by a joint 11, a double-end stud bolt 14, a form-fixture is mounted to the tip projected from the face of slope in the axial direction of the anchor bolt. Further, the head thread part 21 of the anchor bolt is screwed into one tapped hole 12 of the spacer-hardware, and one end thread part of the double-end stud bolt 14 is screwed into the other tapped hole 13. The fixture of a form 3 is mounted to the free end part of the double-end stud bolt 14 to screw one end face side of a cone 15 onto the free end part of the double-end stud bolt 14, and to screw a short screw bolt 16 into the other end face side of the cone in the extending direction of the double-end stud bolt 14.

摘要： PURPOSE:To simplify the construction work and improve the draining ability in a banking by throwing in drainage materials and banking materials inside slope forming frames on which a reinforcing sheet is laid to form a banking body, thereafter constructing a retaining wall by spacer-rods and forms. CONSTITUTION:A slope forming frame 1 is installed on the ground, and the end parts of spacer-rods 2 capable of being adjusted to expand and contract the length are penetrated through slope frames 11 and fixed to them. Next drainage materials 5 and banking materials 6 are thrown on the upper face of a reinforcing sheet 3 such as geo-textile, etc., and the end part of the drainage materials is wrapped up with the upper part of a water-permeable sheet put on the slope frames 11 to prevent fall-down of the drainage materials. After these operations are repeated in sequence to form a banking body, forms 7 are assembled to the spacer-rods 2 along the slope frames 11 at specified intervals, and between the slope frames and the forms, concrete is placed to construct a retaining wall 8. Thus, the banking body can be reinforced to improve its stability.
