[Means for Solving the Problems] In order to solve the above problems, the present invention uses standardized shaped steel such as T-shaped steel, scalene shaped steel, etc., to implant through-holes for connection in the substrate. Underground beams are drilled into the upright boards, and upright temporary pillars with connecting holes protruding from the base plate.
Longer than bracing material in which through-holes for connection are drilled at both ends of a vertical plate that is vertically installed on the substrate, and underground beam material in which through-holes for connection are drilled in the vertical plate that is vertically installed on the substrate. The reinforcing beam material and the front plate, which has a concave cross-section by pouring concrete into the reinforcing section with flat steel with through-holes for connection fixed to both ends, are pre-formed in a factory and then transported to the construction site. After transporting the underground beams to the base of the construction site and fixing them horizontally in multiple rows at predetermined intervals, push the bolts into the connecting holes on the underground beams and tighten them with nuts. In addition to fixing and planting the reinforcement materials, insert bolts into the through holes for each connection between the underground beam materials and the column materials and fix them with nuts, and connect the reinforcing beam materials to the column materials as necessary. Insert bolts into the through-holes and fix them with nuts, and then form an independent or continuous anchor member by pouring concrete behind the reinforcing beams, and at least attach the bolts to the underground beams or the reinforcing beams. One of the stages is made to protrude rearward to form a floating body, and a plurality of front plates are attached to the front of the pillars of the adjacent structures, and bolts are inserted into the through holes for each connection and fixed with nuts.

To explain the operation of the embodiment, the present invention is based on the above-mentioned theory of the principle of retaining walls not collapsing, and as mentioned above, at the construction site, underground beam materials are 1. The pillars 2 and braces 3 are connected and fixed to form the structure 4, but the underground beams 1 located at the lower level relative to the pillars 2 must protrude rearward, and if necessary, The reinforcing beam 30 connected and fixed to the structure 4 will protrude rearward from the underground beam 1. That is, in the present invention, it is necessary that at least one stage of the underground beam 1 or the reinforcing beam 30 protrudes rearward. The underground beam material 1 or the reinforcing beam material 30 that protrudes rearward in one step serves as the bottom plate B in the retaining wall principle shown in FIG. 2.

There are three possible combinations of the positions of the underground beams 1 or reinforcing beams 30 that protrude rearward. The first is the case where the underground beam 1 is protruded backwards at the bottom as shown in Fig. 12 (base shape), and the second is the case where the reinforcement beam is protruded backwards at the center as shown in Fig. 13. When having material 30 (
The third case is a case (upper side type) in which a reinforcing beam member 30 is provided at the upper part and protrudes rearward as shown in FIG.

These three types of forms can be used either when constructing the retaining wall upright or on a slope, and because the structure 4 is fixed to the construction site with a plurality of front plates 7 spaced apart from each other, Although it is necessary, the structure 4 and the reinforcing beams 30 are fixed by performing work such as foundation, back-filling concrete, back-filling chestnut stone paving, anchor work, etc. depending on the situation of the construction site and the purpose of construction, and then fixing the structure 4. The retaining wall construction work is completed by laminating and fixing the front plate 7 to the front part of the pillar material 2.

[Effects of the Invention] Since the present invention is as described above, all of the members constituting the structure, such as underground beams, columns, braces, and reinforcing beams, can be formed from standardized steel shapes. It is inexpensive, and each of the above-mentioned components can be separated and transported to the construction site in a relatively lightweight state, so transportation costs are low, and each component can be connected and assembled to form a structure. Furthermore, since the front plate is not high in height, it is easy to transport, and it is also easy to stack and fix to the structure, which not only shortens the construction period of the retaining wall, but also reduces the construction cost. It has the excellent effect of being inexpensive.

In addition, since the structure has at least one stage of underground beams or reinforcing beams that protrudes rearward, the underground beams or reinforcing beams that protrude rearward are used to prevent the retaining wall from collapsing. In principle, it can serve as a bottom plate and increase the strength of the retaining wall. Furthermore, according to the present invention, not only upright walls but also nearly upright walls can be easily constructed, so a large passage width can be obtained, and
Also, a large amount of usable area can be taken up in the residential area.

Using standardized steel shapes such as T-type steel and scalene type steel, underground beams are drilled into upright plates with connecting holes planted in the substrate, and connecting holes are installed between the substrates. Pillar material drilled on a protruding upright board, through-holes for connection installed vertically on the board, bracing material drilled at both ends of the vertical board, and through-holes for connection installed vertically on the board Reinforcement beams that are longer than the underground beams drilled into the vertical plates are formed, and concrete is poured into the reinforcing sections with flat steel holes drilled for connection that are fixed at both ends to form concave cross-sections. After forming a front plate with a 100-degree angle, and horizontally fixing multiple underground beams at specified intervals at the base of the construction site, bolt the columns onto the underground beams through the connecting holes. At the same time, bolts are inserted between the underground beams and the pillars, and bolts are inserted into the connecting holes and fixed with nuts. Insert bolts into each connecting hole and fix the reinforcing beams with nuts, and then form an independent or continuous anchor member by pouring concrete behind the reinforcing beams, at least for underground beams. A structure is formed by making one stage of either the timber or reinforcing beam protrude rearward, and bolts are inserted into the connecting holes of multiple front plates on the front of the pillars of the structure that are adjacent to each other. A retaining wall construction method characterized by stacking and fixing with nuts.
