[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing earthwork method such as roadbed reinforcement, embankment, slope, roadbed, and road body reinforcement, and a concrete block retaining wall formwork. When constructing reinforced soil such as reinforcement, slope reinforcement, etc., it is used for the reinforced earth construction method that can drain gravity water inside the roadbed etc. without pulling out the underdrain pipe etc. to the reinforced soil, and this reinforced earth construction method etc. A concrete block retaining wall formwork.

[0002]

2. Description of the Related Art Conventionally, as a method of constructing soil for roadbed reinforcement, embankment reinforcement, slopes, roadbeds, road bodies, etc., reinforcement soil such as roadbed reinforcement, embankment reinforcement, etc. ) Is laid, a roadbed is provided on the reinforcing net by a roadbed material, and the surface of the roadbed is used as a road surface. According to this method, the mesh of the reinforcing net is integrated with the soil of the roadbed and the roadbed by the interlocking (anchoring) effect of soil particles in the upper and lower parts of the mesh, so that it is simple. The roadbed can be strengthened by construction.

However, this reinforced earthwork method has the following problems. That is, depending on the type of the reinforcing net, in the case of single-layer laying or multi-layer laying, the end of the reinforcing net may be rolled up during the reinforcement work, resulting in a roadbed portion where the reinforcing net is not laid. In the case of mattress construction, much work is required to cover the roadbed material. It takes time to fix the end of the reinforcing net. It takes time to fix the roadbed and the side of the embankment. There is a problem such as.

Therefore, the inventor of the present invention has proposed a reinforced earth construction method which solves the above problems. This construction method is "a hollow bottomed surface having a concrete block-like surface on one side of a reinforced soil construction site, and a block stacking fitting portion at the bottom portion thereof and a concrete flow-down or overflow portion, and A form having a reinforcing body insertion part such as a reinforcing net or a reinforcing rope on a part of the surface is installed such that the reinforcing body insertion part faces the other side of the reinforcing soil construction site, and the form After directly or indirectly inserting the end portion of the reinforcing body into the reinforcing body inserting portion, the concrete is poured and filled into the formwork to integrate the end portion of the reinforcing body directly or indirectly. And a concrete block body for fixing the reinforcing body to the reinforced soil construction site ".

It has the advantages that it can be done, requires no skill, the construction period can be shortened, and the workability can be improved.

[0006]

However, it has been found that the following problems may occur in the case of this reinforced earthwork method. That is, since the connecting portions formed by the concavities and convexities of the left and right molds are fitted and connected to each other, concrete is filled in the molds to form a retaining wall, and a reinforcing soil is applied between the retaining walls. Water such as gravity water in the reinforced soil cannot be drained to the outside. Since it is necessary to install a separate drainage facility, the construction becomes complicated. That is, since it is necessary to construct the drainage facility before the reinforcement soil construction, the construction period of the reinforcement soil construction becomes long. Drainage equipment is difficult to maintain. Problems such as remain.

The present invention has been made in response to the above-mentioned problems, and its purpose is to strengthen roadbed reinforcement, embankment reinforcement, slope reinforcement, roadbed reinforcement, road body reinforcement and the like. When constructing soil, drainage facilities can be installed by performing formwork installation work without pulling out drainage pipes etc. outside the reinforced soil, and without separately installing drainage facilities.

That is, the formwork 2, 2, ... Is installed at predetermined places on the left and right where roads and railroads are made, and is stacked in multiple stages (usually two stages).
This is the process of installation.

As shown in FIGS. 2 to 11, the mold 2 is made of synthetic resin, concrete, metal or other material having a hollow bottomed flat rectangular shape whose surface is formed in the same shape as a concrete block. A formwork, in which a pattern or the like is formed on a front surface (in other words, a front surface) 4, similar to a concrete block, an opening 6 is formed in an upper portion, and a reinforcing member 3 is formed in an upper rear surface. Reinforcement body insertion portions 5 for inserting the end portions 3a and 3b are formed, further, a convex portion 7 forming a fitting portion is formed on the bottom surface, and a drainage guide passage 8 is further formed on the lower portion of the side surface. ing. The opening 6 is a filling port for engaging with the convex portion 7 of another formwork 2 to be stacked and for pouring and filling fresh concrete. Further, the convex portion 7 is an engaging portion for engaging with the opening portion 6 of the other formwork 2 to be stacked, and has a shape which is smaller than the peripheral wall surface 9 of the formwork 2 and protrudes downward. . Further, one or a plurality of ready-mixed concrete flow-down holes (or overflow holes) 10 are formed on the surface of the convex portion 7, in other words, on the bottom surface 9 of the formwork 2.

Here, the flow-down hole 10 is usually 3 although it differs depending on the shape and form of the concrete block itself.
The holes are formed at intervals of 0 cm, and the size is about 3 to 10 cm in diameter. However, other sizes may be selected.
A notch 11 is provided on the upper side surface of the mold 2. The notch 11 is a notch for installing the rebar 12 that connects the formwork 2, 2 ... In the lateral direction. here,
