。Generally speaking, in the reinforcement method for sloped ground, as shown in Figure 3, it is common to construct a so-called slope framework in the form of a lattice of beam-shaped concrete structures. In such a case, the formworks 1.1 will be assembled in a crosswise manner at the intersection of the legal frames. In addition, the thickness of each side of the frame varies depending on the construction conditions.The formwork 1 used in the construction site is manufactured as a fixed object with a length suitable for transportation, so at the site, It is then cut to the required length or added to the required length, and then assembled to the predetermined dimensions. In addition, when constructing a legal framework as shown in Figure 3, the anchor 7 facility is driven into the ground at the intersection of the legal framework, or in the case of hard ground, holes are drilled with a drilling machine and anchor bolts, etc. Insert it to connect it with the ground. Also,
Anchor 7 is the above idiot 1t71. As shown in Figure 3, the upper shaft bar 2.21rA passes through the intersection.
It is also possible to connect the formwork 1.1 and the ground 4 by erecting an anchor connecting member 6 and connecting the anchor 7 thereto.
このようにすれば、アンカー7は連結材6で支持される
ため、法枠の寸法の大小にかかわらず確実な抵抗力が得
られる。In this way, since the anchor 7 is supported by the connecting member 6, a reliable resistance force can be obtained regardless of the size of the frame.

The axial reinforcements 2.2 are positioned at intervals in the transverse direction of the plane. In this case, the net-like body 3 is formed without the axial reinforcement 2.2, and the axial reinforcement 2.2 is formed separately from the net-like body 3.

Then, as shown in the figure, attach the connecting bars 9.9 to the mesh body 3 and use PA fat! ! Binding material 10 such as wire rod
.. 10. In the formwork 1 of this embodiment, as shown in Figure tjSB, when the formwork 1.1 is assembled, the shaft reinforcement 2.2 can be positioned considerably inward from the mesh body 3.3. Therefore, since the shaft reinforcement 2.2 is buried sufficiently deep from the surface of the poured concrete 8, there is no problem even if the concrete cover of the mesh body 3.3 is small, so that the formwork 1, Concrete 8 to 1 room
After the pouring of the formwork (1.1M)
It becomes possible to reduce or omit the spraying of t, which makes it possible to simplify layer construction and reduce costs.

工ができる。As explained above, the earth reinforcement structure of the present invention integrates the shaft reinforcement and the net-like body using a fiber bundle made of lightweight, high-strength fibers impregnated with a highly corrosion-resistant resin material. The method is characterized in that the formwork is formed by molding and hardening to form a formwork, the formwork is arranged in parallel on a slope, a concrete neck is poured between the formworks, and the formwork is buried in concrete. Since the formwork is also used as reinforcement,
Assembling the formwork can be done immediately with reinforcement, greatly simplifying the work of assembling the formwork and arranging the reinforcement.
Compared to conventional construction steel materials, it is arranged with a corner from the net in the direction transverse to the plane of the net and the shaft reinforcement and the net are connected by horizontal connecting reinforcements. Very! ! It is a plate, which greatly reduces work, especially on slopes where workability is poor, and enables efficient and inexpensive construction.
