    • PROBLEM TO BE SOLVED: To provide an earth retaining wall capable of being installed on a soldier pile without assembling a block and accordingly increasing construction efficiency as well as its construction method and its block and to provide the earth retaining wall facilitating the installation and pile of the block, having the high effect of permeability, sufficiently bearing up soil pressure and becoming familiar with the soldier pile and the block.
      SOLUTION: In the block (1) installed around the erected soldier pile (3) and piled up to construct the earth retaining wall (2), a main body section (11) having a hole (12) wherein the soldier pile (3) is inserted and a flange section (13) extended in the longitudinal direction of the earth retaining walls (2) constructed on both sides of the main body section (11) are integrally constituted, and there is positioning unevenness in the flange section (13) in the case the block is piled up.

    • PURPOSE:To reduce a construction period, construction cost and labor in the construction of an open-cut tunnel. CONSTITUTION:Reinforcing steel 6 formed of shape steel is fitted to the outer peripheral surface of extremely thin PC lining form plates 1, 1, 1', along the circular direction thereof through connecting steel 7, and supporting material for supporting the PC lining form plates is installed expandably by a jack along the arch shape of a tunnel to be constructed, thus forming a temporary bearing assembled frame 14. This temporary bearing assembled frame 14 is installed in the movable and travelable state at the invert part 13 of channel cross section of a tunnel lower half part constructed at the bottom part of the open-cut ground. In this temporary bearing assembled frame, the PC lining form plates are assembled in arch shape and fixedly placed on both side parts of the invert part 13, and the adjacent end parts of the reinforcing steel fitted to the PC lining form plates adjacent in the ring direction are jointed in the integrated state. After arranging a series of reinforcements 26 on the outer peripheral part of the PC lining form plates, an outer form 29 is assembled in arch shape on the outside of the reinforcements 26. Cast-in-place concrete is filled in a gap between the outer form and the PC lining form plates, and a process of removing the outer form after the curing-hardening of the concrete is performed continuously in regular succession by moving the temporary bearing assembled frame 14 forward.
