摘要： PROBLEM TO BE SOLVED: To provide an earth retaining wall/RC composite structure and its construction method capable of simply connecting a steel material as the core of the earth retaining wall and a reinforcement of the body structure or dowel at a site, and promoting thereby the integrality of the earth retaining wall and the body structure. SOLUTION: A mechanical joint 2a having a female screw is mounted on the body structure side of a steel bar 2 connecting between inside and outside flanges of the steel material 1 as the core of the earth retaining wall, and it is so constituted that it can be opened in the surface position of the steel material 1. A mechanical joint 7a having a similar female screw is mounted to the end of the reinforcement 7 of the body structure. Both mechanical joints 2a and 7a have inverse screws, a relay bolt 5 having different directions of screws in right and left is used, and the relay bolt 5 is rotated around the shaft to connect the steel material 1 to the reinforcement 7 while pulling both mechanical joints 2a and 7a near to each other.

摘要： PURPOSE:To eliminate damage to the cross section of top plate by shortening the setting depth of sheathing materials by a method in which a coping stone serving as guide wall in combination is connected to the top of a sheathing material, the inside of the sheathing material is excavated for an underground continuous wall to the lower end of the top plate, and the top plate is constructed on the head. CONSTITUTION:The ground on both sides of a place where an underground continuous wall is to be constructed is improved while mixing it with a hardener, and sheathing materials 8, e.g., H-steel, etc., are vertically set. Concrete for guide wall 6 in an underground continuous wall construction method is placed up to the height of the excavated face of a top plate 2 in such a way as to bury its head. A coping stone 4 serving as guide wall 6 is provided for the head of the material 3 for connecting and underground continuous wall 1 is constructed to the height of the top plate 2 until a given depth is reached inside of the material 3. The ground surrounded by the material 3 is excavated to the lower end of the top plate, and the top plate 2 is constructed on the wall 1. The needs for shoring strut construction can be eliminated during the excavation of top plate portion, and the construction work can thus be economized.

摘要： PURPOSE:To exactly support horizontal forces to be applied by a method in which a bearing wall, a form box, and a reinforcing bag cage are set in a trench, the bearing walls on both ends of the form box are connected with tie rods, concrete is placed into the form box, and cover plates are set in front of the excavating direction. CONSTITUTION:A given depth of trench 1 is excavated in the ground, and a form box 2 consisting of a bearing wall 3 and side plates 4 and reinforcing bars 6 are integrally penetrated into the trench 1. The form box 2 is fixed with tie rods 10 through the wall 3 by using nuts 11. Concrete 13 is placed in the rare part of the excavating direction of the box 2, and cover plates 14 are set in front of the excavating direction of the box 2 to close the trench 1. The ground in front is excavated. The underground wall can thus be exactly constructed without causing the displacement of the form box because of support by the tie-rods and can withstand the horizontal forces such as soil pressure, etc.

摘要： PROBLEM TO BE SOLVED: To provide an earth-retaining wall and an RC synthetic structure capable of considerably facilitating field work by perforated steel plate dowels previously mounted to the core material of an earth-retaining wall and superior in incorporatedness by the dowels. SOLUTION: A perforated steel plate dowel 2 is previously mounted by shop- welding in a longitudinal direction to H-shaped steel 1, which is the core material of an earth-retaining wall to be previously constructed. Holes 2a are formed at regular intervals in a band-shaped steel plate in the perforated steel plate dowel 2, and the perforated steel plate dowel 2 functions as a dowel by the entrance of the concrete of a main body wall 3 into the holes 2a and the increase of adhesion with the concrete. Vertical reinforcements 5a and horizontal reinforcements 5b are arranged in the main body wall 3, and insertion reinforcements 4 are inserted into the holes 2a of the perforated steel plate dowel 2 as necessary to place concrete.

摘要： PURPOSE:To prevent instrusion of paste and debris into a bracket metal by connecting the bracket metal to a horizontal reinforcement, making it free to insert and remove an engagement fitting installed on a coupler into and from the bracket metal and attaching a thin iron plate to close a slit at the time of no insertion. CONSTITUTION:A thin iron plate 7 is fixed on both sides of a slit 3 of a bracket metal 1 by tapping screws 8. At that time, the head end of the thin iron plate 7 is projected in the direction of the slit 3, and both of them are reciprocally butted each other. At the time when an engagement fitting 2 is not inserted into the bracket metal 1, the head end of the thin iron plate 7 is adhered and the slit is closed. When the engagement fitting 2 is inserted from an opening of the bracket metal 1, a coupler plate 6 is adhered at the head end part of the thin iron plate 7. Consequently, at the time of depositing concrete of a following element and drilling, it is possible to prevent instrusion of paste and debris into the bracket metal 1.

摘要： PROBLEM TO BE SOLVED: To provide a cast-in-place construction method according to which a stabilizing liquid in an excavated hole is maintained in a good quality condition, and adhesion of mud cake to a hole wall at excavation is prevented or suppressed.
SOLUTION: The cast-in-place construction method is comprised of the following four steps. In the first step, a rod pipe 24 of an excavator 10 is driven for rotation and lowered, and excavation is carried out by a cutter head 26 arranged on a lower end of the rod pipe. In the second step, the stabilizing liquid is supplied from a lower opening of the rod pipe into the excavated hole 28. In the third step, the stabilizing liquid is supplied from the vicinity of a hole aperture of the excavated hole 28 to the excavated hole. In the fourth step, a suction port of a slurry lifting pump 60 is arranged in the excavated hole in a range of a predetermined height from a deepest bottom of the hole, and the slurry on the bottom of the excavated hole is recovered. According to the method, the above four steps are simultaneously carried out, and thereafter ready mixed-concrete is placed in the excavated hole. Therefore, according to the method, the stabilizing liquid in the excavated hole is maintained in a good quality condition.
