The present invention, the pipe base to rotate freely at any angle depending on the angle of the tension member to be tension as it passes through the pipe the seat of the pressure plate on the sleeve of the various angles that are installed at the underground continuous wall of the bracket for the anchor head of the underground continuous wall and, because of this that can be settled without the upper part of the tension member is a bending of course, to be actively respond to one type of sleeves of different angles.
Bracket anchor head of the underground continuous wall according to the invention, it doedoe downwardly inclined perforations alone construction through the sleeve of the underground continuous wall is supported on a wall or a fixed pressure plate of the underground continuous wall surrounding the sleeve tension member top of the parts forming the anchor the guides, including an anchor head bracket for the underground continuous wall for fixing the anchor head anchorage, the anchor head bracket is in surface contact with the fixed pressure plates and is provided in the sleeve upper end of the elongated lower yen fixed pressure plate of and the pressure plate of the through hole group is to be arc-shaped obstacle to take on the lower inner surface protruding square, is through a long hole of the pressure plate rotatably provided in the small intestine angle range hollow base of the blank pipe-shaped pipe, and a middle of the pipe base pan-fitted into through holes provided in the angle part which slot is allowed around the two through holes Forms a straight line on the pressure plate can be rotated in the slot on both sides and being composed of two support pins mounted.
