摘要： PROBLEM TO BE SOLVED: To accurately specify positions of a support layer and a weak intermediate layer when constructing a pile. SOLUTION: This construction method adopts a rotary press-in pile having the constitution for rotatably pressing the whole in the ground by axially connecting a lower pile 6 having the tip deeply embedded in the support layer 3, an intermediate pile 7 arranged in a position of the intermediate layer 4, and an upper pile 8 arranged in an upper part of the intermediate layer. First of all, only the lower pile is rotatably pressed in, and after specifying a position of the intermediate layer, the thickness, and a position of the support layer by determining an N value in the respective depths of the ground 1 from a required torque value at that time, the lower pile is inversely rotated and pulled up, and the length of the lower pile, the intermediate pile, and the upper pile is properly adjusted. The whole is rotatably pressed in the ground by connecting these piles, and a tip part is deeply embedded in the support layer. When rotatably pressing in only the lower pile, the length is preset to the length by adding embedment depth length to a supposed distance up to the intermediate layer from the support layer, and the part is rotatably pressed in by using a spline pile. The intermediate pile is connected by a hinge structure for substantially transmitting no bending moment to the lower pile and the upper pile. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To obtain a reasonable turbine-building which is able to support the horizontal load caused by such as seismic force or earth pressure by a building structure entirety, by connecting building structural columns close to a supporting frame to each ether by means of transmitting/supporting the horizontal load with spaced in a side-edge direction of the supporting frame. CONSTITUTION:A turbine-building 1 has in its center a supporting frame 2 for a turbine or a generator installed on the same foundation slab with a gap 4 secured between the building structure body and the supporting frame 2. In the center of the building 1, an opening is formed on respective floor slabs 5 of the building. Respective building columns 6a, 6b which are adjacently disposed to the supporting frame 2 in the direction perpendicular to the longitudinal edge direction of the supporting frame 2 are connected to each other with a bearing wall 8 such as reinforced concrete construction through the range from the foundation slab to the under part of the deck of the supporting frame 2. Thus the horizontal load produced in the above mentioned orthogonal direction is transmitted to the building structural body through the bearing wall 8, whereby the horizontal forces produced on respective structural bodies of the turbine-building 1 are uniformly distributed.
