摘要： PROBLEM TO BE SOLVED: To allow a PC steel strand withdrawal operation without dispersing filler.
SOLUTION: A device body 14 comprises a hollow case body 30 disposed at a position for covering an unbonded sheath terminal 18a with the unbonded PC steel strand passed therethrough, a scraper 56 disposed and held so as to be brought into slidable contact with the surface of the PC steel strand 16 in the hollow case, and a fixing means 46 for non-movably fixing and holding the hollow case body to the unbonded sheath 18. The filler on the surface of the PC steel strand can be scraped off by the sliding of the scraper 56 on the PC steel strand following the withdrawal of the PC steel strand 16 from the unbonded sheath 18. The filler scraped off by the scraper can be discharged from a discharge port 31 provided in the hollow case body 30 to the outside of the hollow case body.

摘要： PURPOSE:To stuff up an anchor setting hole definitely and firmly by pressurizing and holding a hardening fluid only in a limited specified area around the anchor setting hole when constructing a ground anchor. CONSTITUTION:An anchor member 11 is installed into an excavation hole casing 9 which forms an excavated hole 10 by way of an anchor setting hole 2 while cement milk is injected thereinto, thereby pulling out the excavation hole casing 9 by a definite length at time with water stopped and separating gradually. When pulling out the final casing unit body 6, the anchor setting hole 2 is water-stopped by means of a primary packer 14 installed to the anchor member 11 and a closing means. Then, a hardening pressure fluid is supplied to a secondary packer 15 installed to the anchor member 11 and the size of the secondary packer is expanded, thereby stuffing up the anchor setting hole 2.

摘要： PURPOSE:To sucre the covering thickness of grout by a method in which a linked centralizer is fixed to the tip of earth anchor and projected outwards in an excavated skew pit to position the earth anchor at the center of the pit. CONSTITUTION:A tip centralizer 2 is attached to the tip cap 5 of a tension member 1 and an intermediate centralizer 3 is also provided to an attached steel tube 6 at need. The centralizers 2 and 3 are each made up of a link device projected outwards by spring and a stopper to hold the projected position. A cylindrical casing is inserted into an excavated slew pit and the centralizers 2 and 3 in the contracted state are inserted into the casing. The casing is drawn out and the centralizers 2 and 3 are expanded to position a tension member 1 at the center of the pit. During the period, a grout is injected to form an anchor body 4, and after it hardens, the head of the member 1 is tensed and fixed by a tenser jack. An essential covering thickness of the grout in the skew pit can thus be sufficiently secure.

摘要： PURPOSE:To increase the effect of an anchor by providing a tip holder to the front end of a load resisting body, providing an upper end spacer to the rear end of the load resisting body, and lifting the load resisting body in a diagonal excavated hole by the holder and spacer to support. CONSTITUTION:A pilot cap 7 is provided to the end of a load resisting body 1. An upper end spacer 8 capable of controlling the expansion and reduction of the diameter is provided to the rear end of the load resisting body 1. The load resisting body 1 is lifted to the height equivalent to the thickness of the protective concrete cover for filler 4 upward of the lower bottom of a diagonal excavated hole 3 by the cap 7 and spacer 8. In addition, the force-fit of the filler 4 in the peripheral part of the load resisting body 1 is made over the range of at least the length of the load resisting body 1 in the excavated hole 3 to fill.
