摘要： PROBLEM TO BE SOLVED: To provide a construction method of a concrete structure attaining efficient construction without interfering with arrangement of reinforcements while sufficiently suppressing cracking even if using ordinary concrete.
SOLUTION: Reinforcements 1 and a plurality of ducts (spiral ducts) 2 are built in a concrete placing space. In this case, priority is given to building-in of the reinforcements 1, and after building in the required number of reinforcements 1 according to a design basis, the plurality of ducts 2 are built in utilizing a space not interfering with the reinforcements 1. Concrete is then placed in two stages divided into the peripheries of the ducts 2 and the inside of the ducts 2. Since concrete is placed in two stages, even if ordinary concrete is used as concrete, the total calorific value by hydration is kept low, and a temperature gradient in a peripheral concrete layer 3, not to mention concrete layers in the ducts 2, becomes small to suppress cracking.

摘要翻译：要解决的问题：提供一种获得有效结构的混凝土结构的施工方法，而不会干扰加强件的布置，同时充分抑制裂纹，即使使用普通混凝土。解决方案：加固件1和多个管道（螺旋管道）2内置在混凝土浇筑空间中。在这种情况下，优先考虑加固件1的加入，并且在根据设计基础构建所需数量的加强件1之后，利用不与加强件1干涉的空间来内置多个管道2。然后将混凝土分为两段，分成管道2的周边和管道2的内部。由于混凝土分为两个阶段，即使使用普通混凝土作为混凝土，水合物的总发热量保持较低，并且周边混凝土层3中的温度梯度，更不用说管道2中的混凝土层变小，以抑制开裂。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a pier reusing method for reusing a structure that cannot exert functions of a pier due to its aging, deterioration, or the like, without crushing the same.
SOLUTION: In reusing the structure that cannot exert the functions of the pier 1, the pier reusing method comprised of the following steps is employed. In the first step, a steel pipe pile 2 is cut away from the pier 1 and superstructure work 10 formed of a floor slab portion 5, a beam portion 4, and a pile head portion 3 is removed. In the second step, the removed superstructure work 10 in its original condition or in a condition in which a new structure or a new object is added to the original superstructure work, is set on the ground, in the ocean, or in a river, to thereby form a new structure having new functions. Thus the pier 1 can be reused without crushing the same, and therefore dust or noise which is unavoidable when crushing is carried out, occurs, whereby a large load is not imposed on the environment.
