欠点がある。 As one of the slope protection methods, it is known to install a frame-like structure, that is, a slope frame, on the slope. In this construction method, reinforced concrete slopes are often constructed on slopes, but the disadvantage is that assembling the formwork is troublesome and requires a lot of labor and time. A construction method has also been implemented in which a steel plate is used instead of the formwork and the steel plate is embedded by spraying mortar, but this method has the drawback of insufficient rigidity and strength.

護を図らんとするものである。 This invention aims to solve the above-mentioned drawbacks of the conventional slope construction method, and involves applying mortar at required intervals in the longitudinal direction of the upper surface of the slope frame, which is formed into a tubular or cross-sectional shape. An inflow hole is opened, this frame is installed on the slope, and it is fixed to the slope with an anchor, and then mortar is poured into the hollow part of the frame from the mortar inlet and the upper end of the slope frame. By doing so, it is possible to construct a slope structure that is easy to construct and has great strength, thereby stabilizing and protecting the slope.

もできる。 Figure 1 shows a metal legal frame used as the framework of the legal frame in this invention.
This legal framework frame 1 is formed into a tubular shape with a square cross section, and on its upper surface, inflow ports 2 through which mortar such as concrete and mortar flows are provided at required intervals along the longitudinal direction of the legal framework frame 1. At the same time, a through hole 3 is provided at an appropriate position through which an anchor for fixing the slope frame 1 to the slope is inserted. Further, the slope frame 1 is not limited to a tubular frame as shown in Fig. 1, but may also be a frame with a round cross-section, with the lower part in contact with the slope open, as shown in Fig. 2, for example. can.

して地中に打込んで法面に固定させる。 In this invention, the above-described legal framework frame 1 is installed on a slope as a skeleton of a structure, but if the slope is extremely uneven, the ground is leveled in advance. If the slope frame 1 is tubular (FIG. 1), mortar may be applied on the slope and then installed thereon. If the legal framework frame 1 is required to have even greater strength, reinforcing reinforcing bars 4 are installed inside the legal framework frame 1.
Place reinforcement. The reinforcing reinforcing bars 4 can be easily arranged by assembling several main reinforcing bars in advance into the legal framework frame 1 so that they can be inserted, and inserting them from the opening at the upper end of the legal framework frame 1. and,
Anchors 5 are inserted into the through holes 3 of the slope frame 1 and driven into the ground to be fixed to the slope.
法枠フレーム１の固定後は、第３図に示したよ

填させるのである。 After fixing the legal framework frame 1, as shown in Fig. 3, first pour mortar 6 from the lowest inlet hole 2 as shown by arrow A, then pour mortar 6 from the upper inlet hole 2 as shown by arrow A. Then, from the inflow hole 2 above it, pour it in order as shown by the arrow C.
Finally, mortar is poured into the frame 1 from the opening at the upper end thereof in the direction of arrow D to fill the frame 1 with mortar.

Adhesion of mortar 7 is good.

果をあげ得ることはいうまでもない。 In this invention, the above-mentioned structure does not have to be applied to all structures formed in a lattice shape as a legal frame. For example, as shown in Fig. 8, only the slope of the slope in one direction of the slope is constructed using the structure according to the present invention, and the slope of the slope in the direction that intersects with the slope is constructed using the conventional structure. It can also be constructed by assembling the frame 9, arranging reinforcing bars 10, and pouring mortar. However, even in a slope that is long in the direction that crosses the slope line of the slope, it is possible to pour concrete 6 times into the slope frame 1 by opening the inflow hole 2, so all of the slope It goes without saying that even more effects can be achieved if the construction according to the present invention is applied to objects.

発揮するものである。 As explained above, the present invention provides inflow holes for mortar at required intervals in the longitudinal direction on the upper surface of a slope frame formed into a tubular shape or a square cross section. The structure was installed in the slope and fixed to the slope with anchors, and then mortar was poured into the hollow part of the slope frame from the mortar inlet and the upper end of the slope frame, making it easier to assemble the formwork. In addition to saving labor and significantly shortening the construction period, it is more efficient than the mortar spraying method because the mortar flows into the slope frame and is poured into the slope frame. Since pouring can be carried out through the inflow hole opened at the top of the slope, filling the slope frame is reliable and easy, especially for construction on slopes with gentle slopes or slopes in the direction across the slope line. It can also be applied to construction, and has many excellent effects, such as being able to construct a slope structure with excellent slope stability and protection.
