Abstract

PURPOSE:To enable simultaneous construction above or under the ground and reduce cost by constructing floor on the first floor which becomes a work floor after sinking a caisson and constructing cloth foundation. CONSTITUTION:A cotter 3 made with metallic cotter reinforcement is mounted at a caisson blade mouth section 2 of a side wall 1a after a caisson 1 is sunk. A continuous footing 4 is constructed by placing concrete and integrated with the caisson blade mouth section 2. A floor on the first floor 5 which becomes a work floor 5 is constructed by preventing sink of the caisson 1 and ensuring support force with the construction of the continuous footing 4. Then, a pile 6 is constructed, and the underground section of a foundation slab 7, an underground body 8 and the like is constructed. At the same time, a body 9 on the ground is constructed. It is possible to reduce construction period and cost when a building A is built sequentially.

(Means for Solving the Problems) The gist of the method for simultaneously constructing above-ground and underground structures according to the present invention is to solve the above-mentioned problems and achieve the objectives. build the foundation,
After this, by constructing the first floor which will be the work floor,
The purpose is to be able to construct above-ground and underground sections at the same time. (Function) As described above, according to the method for simultaneously constructing above-ground and underground structures according to the present invention, after the caisson is sunk, the cloth foundation is first constructed, thereby preventing the caisson from sinking and increasing the bearing capacity. This makes it possible to secure a work floor (first floor) and proceed with the construction of the underground and above-ground sections at the same time.Then, as in the past, after the construction of the piles and foundation slab, This eliminates the constraint of having to build from the underground part to the above-ground part in sequence.

FIG. 1 is an explanatory diagram showing the construction order of the simultaneous construction method according to the present invention. FIG. 2 is also a partially enlarged longitudinal sectional view. In the present invention, the procedure for sinking the geson 1 to a predetermined position is the same as that described in the conventional example (Fig. 3 (a), part 9), and will therefore be omitted. After caisson 1 was sunk,
A cotter 3 is provided at the caisson blade opening 2 of this side wall 1a. As shown in FIG. 2 (A), the cotter 3 consists of a metal cotter line at the caisson blade opening 2. Then, concrete is poured to construct a cloth foundation 4, which is integrated with the caisson blade opening 2.

As another embodiment, the cotter 3 may be provided by protruding a protrusion 3a from the cutting edge portion 2 of the side wall 1a of the geson 1, as shown in FIG. 2 (portion), for example. In short, this cloth foundation 4 is n! The purpose of this construction is to prevent caisson 1 from sinking and ensure its supporting capacity. Then, construct the first floor 5, which will be the work floor (Figure 1 (b)
