Construction of a lattice-like slope structure on a slope has been carried out. The method of constructing this slope structure is to arrange and assemble a formwork made of deformable materials such as wire mesh and cardboard on the slope of the site, install reinforcing bars, and then pour concrete. There is an on-site pouring method for constructing a lattice-like structure.

Beam members are manufactured in advance at a factory, and then made into vertical beams,
There is a method of assembling horizontal beams in a lattice shape on site (see JP-A-48-62205). This construction method is shown in Figs. 11, 12, and 13. Reference numeral 1 indicates a longitudinal beam, and reference numeral 2 indicates a horizontal beam, both of which are made of a steel pipe 3 serving as a core material, with both ends exposed and covered with concrete. 4 is a steel joint. These are all pre-manufactured in a factory, and the construction method involves connecting vertical beams 1 and horizontal beams 2 in a lattice-like manner through joints 4 on the slope at the site, and anchoring them at the 4 joints at the intersections of the lattice.

Since a lattice-like slope frame structure is constructed by simply welding the vertical beams 1 and the horizontal beams 2 to the joints 4, the slope surface must be flat, and there should be no undulations (unevenness) in the slope ground. In some cases, it is necessary to cut down the ground and level the ground. In addition, if the slope is a curved surface that is curved in the horizontal direction of the slope, it is necessary to use a joint with a connection angle that corresponds to the curved surface, but this is complicated and it is difficult to It is not easy to deal with the shape of the slope. In addition, with the on-site pouring method, the formwork can be assembled according to the slope of the site, so the above-mentioned cutting and leveling of the ground is not required, but it is time-consuming to construct, as in the case of "double construction."
