摘要： PROBLEM TO BE SOLVED: To eliminate the need for the penetration section of a continuous underground wall, to reduce cost and to shorten the term of works by forming an uplift-receiving section near a bottom section on the inside of the continuous underground wall constructed around a structure body. SOLUTION: A structure body 1 is constructed in the ground, a continuous underground wall 2 is built around the structure body 1, and bottom slabs 3 are erected on a bottom section on the inside of the continuous underground wall 2. Uplift receiving sections 21, 21 having continuously or intermittently projected or recessed shapes, etc., are formed to sections slightly upper than the base of the internal surface of the continuous underground wall 2. Consequently, uplift working to the bottom slabs 3 by the reaction of a base ground is transmitted to the continuous underground wall 2 through the uplift receiving sections 21, and the floating of the structure body 1 is prevented surely. Accordingly, the penetration section of the continuous underground wall 2 is unnecessitated, and cost is reduced and the term of works is shortened while construction management can be facilitated.

摘要： PROBLEM TO BE SOLVED: To provide a device and method for continuously arranging a reinforcing bar, in a construction step of an underground continuous wall, in which a flexible reinforcing bar is used. SOLUTION: A reinforcing bar curing base 29 comprising a beam material is provided at the top end of a continuous wall construction groove and a reinforcing bar arranging device comprising a frame body 10, a reinforcing bar feed means, and a reinforcing bar guiding means is provided on the upper part of the groove. Reinforcing bars are delivered by the reinforcing bar feed means and after a required number of reinforcing bars are formed into a predetermined bundled state by means of the reinforcing bar guiding means, the bars are bundled together at a predetermined pitch to form main reinforcing bars S. And the bars S are pulled out to the base 29 and a lower frame F1 is inserted into the interior of the bars S so as to be suspended therein. Next, while a horizontal reinforcing bar panel Y is being attached to the bars S, the frame F1 is lowered to the groove and an intermediate frame and a top frame are attached at a predetermined interval. Top parts of the main reinforcing bars are fixed to the base 29 using a wedge member and the main bars S are cut off at a level above the fixed point. And concrete is placed up to the lower part of the base 29 to construct a continuous wall and then the base 29 is removed.

摘要： PROBLEM TO BE SOLVED: To dispense with a high working space at the upper part of an exavation hole, by attaching lateral reinforcements taken out of a containing device of the lateral reinforcements to the periphery of vertical reinforcements in turn while inserting a plurality of vertical reinforcements at a specified position in an excavated hole. SOLUTION: A containing device 2 of lateral reinforcements is installed at the inner peripheral face of the opening end of an excavated hole 1. A guide frame 5 is arranged above a curing base 4 by supporting it by legs 51. Required number of vertical flexible reinforcements 6 drawn from a drum are inserted in the guide pipes 52 corresponding thereto respectively and inserted into the excavated hole 1 after a shape-retaining frame has been fitted. Lateral reinforcements 3 taken out of the containing device 2 are fitted to the periphery of the vertical flexible reinforcements 6 by welding or the like in parallel to the above insertion work. The lateral reinforcements 3 are urged so as to be extruded upward and hence, they can be taken out of the containing space 23 of the lateral reinforcements with a little force.

摘要： PURPOSE:To make it possible to prevent water leakage and enhance economical efficiency by reducing the wall thickness of a thin wall area. CONSTITUTION:In a continuous underground foundation 1 which builds up integrally a thin wall area 13 on the lower part of a thick wall area 11 by way of an offset portion 12, one end of the thick wall area 11 on the upper end side is opened, and what is more, an injection passage 3, whose other end is opened, is formed on the side of the offset portion 12. A water stop material is injected into a ground around the offset portion 12, thereby improving the ground.

摘要： PURPOSE:To lower overhead clearance restriction in the case of excavation by making it possible to separate an excavator main body from a pump unit, and bearing them on a bearing device to make it possible to move them to an excavating position. CONSTITUTION:An excavator main body (a first main body) 100 suspended by a bearing device 300 and a pump unit (a second main body) 200 are moved to an excavating position by a self-traveling device 39 and are fixed with a jack 40. The main body 100 is lowered by using a hanging cylinder 37 and a hanging chain 38 to excavate. After excavation is made down to a specific depth, a slide cylinder 34 of the device 300 is operated to move a head sheave 35 forward, and the unit 200 is moved toward above the main body 100. A hydraulic winch 31 and a hydraulic reel 32 are operated, the unit 200 is gradually lowered, a connecting section 18b of the unit 200 is inserted in a connecting section 18a of the main body 100 and is fixed with a connecting pin 17. The chain 38 is removed, the hydraulic winch 31, the hydraulic reel 32, a hose reel 43, a submerged pump 21, a motor 14 and guides 15 and 25 are operated, and a drum cutter 11 and a ring cutter 12 are revolved to excavate.

摘要： PURPOSE:To simplify the construction work and reduce the cost, by erecting guide walls on the ground and arranging them on constructing a continuous wall in the underground with a shallow water level and keeping the level difference between the underground water level and a stabilizing liquid with a specified value. CONSTITUTION:The underground water level is measured in advance and a guide wall 13 provided with an upper retaining wall 14a to get a necessary water level difference 5 is installed in the ground 11 and a ditch 12 is excavated. A stabilizing liquid preventing collapse of the side walls on cutting this ditch, is injected so that the water difference (t) shows a specified figure (about 2m or more). After cutting the ditch, a steel rod cage is erected inside and concrete is placed to constrtuct a continuous wall. In this way, the construction work can be simplified without subsidence of the ground.
