Description of the Invention (1) [Technical Field] The present invention relates to wall panels and reinforced soil structures that can be used to maintain the supplementary soil layer of supplemental soil. [Technical background] For example, an example of the reinforced soil structure constructed by the replenishing soil construction shown in FIG. 5 is provided along the front side of the soil replenishing layer 1 at the front end of the soil replenishing layer 2 formed by the soil replenishing. A plurality of wall panels 2 1 laterally adjacent to the vertical direction. In addition, a connecting metal piece 22 is protruded on the back of each wall panel 21, and each of the wall panels 21 is connected to a component made of steel and the like buried in the soil layer 20 through the connecting metal piece 22. The soil reinforcing material 23 is fixed to the front end of the soil replenishment layer 20. However, the wall panel 2 1 is generally formed of rigid materials such as concrete, but on the other hand, since the supplementary soil forming the supplemental soil layer 20 is granular, it is easily deformed due to compression during rolling. In particular, the connecting portion a connecting the metal pieces 22 and the reinforcing material 23 is easily displaced during the rolling of the reinforcing layer 20, affecting the movement of the surrounding soil particles, and finally causing a crack. ^ Also, although the use of on-site output materials as supplementary soil is extremely economical, the compressibility of the supplementary soil is poor due to its poor texture, and the wall panel is prone to displacement and deformation. And i ', because the thickness of the concrete wall panel of the general reinforced earth retaining wall is 18 cm ~ 2 2 cm, not only because a large amount of material is required, this paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ) (Please read the notes on the back to write this page).

Description of the invention (2) It lacks economic benefits, and because of its heavy weight, it has transportation costs and poor workability of assembling wall panels on site. Among the problems mentioned above, to solve the problems caused by the use of compressive supplementary soil, the method of connecting the concrete wall panel and the supplementary soil reinforcement material by a pulley joint is generally known. Although the method of using this pulley joint is a method that responds to the compression of the supplemental soil and makes the connection portion a highly compliant, the position of the connection portion a of the wall panel and the reinforcement reinforcement material tends to occur due to the compression of the supplemental soil. The displacement and deformation cause the stress state to easily change, and there is a problem that the joint portion a is liable to cause undefined stress to cause deformation. Therefore, the stress generated by the joint portion a changes with time, which is unpredictable and complicated. There is a risk that stress may cause deformation of the connecting portion a. Generally speaking, the displacement and deformation of the wall panel of this reinforced soil structure will spread the load caused by the transversion pressure toward the compression side of the supplementary soil layer 20, and the compensation generated by the compression of the supplementary soil. Changes in the horizontality of the soil reinforcement material, and the resulting decrease in the tensile resistance of the soil reinforcement material, as well as the stress concentration in the connection portion, the relaxation caused by the connection portion a during rolling, and the connection portion a Deformation occurs. In addition, the compression of the supplementary soil layer 20 due to the loaded load causes deformation of the supplementary soil reinforcement material 23 and the wall panel 21 'or the stress concentration of the connecting portion a may cause displacement and deformation of the wall surface. As a result, in order to respond to the unclear stress changes as described above, it is necessary to increase the thickness of the wall panel or increase the connection with the function of a pulley joint.

Description of Invention (9) 4A ·. At this time, the connection plate 3 a of the soil reinforcing material 3A can be inserted between the connection plates 4 b and 4 b of the connection metal piece 4A ', and the connection bolt 4 can be connected to the connection hole 4 c and the connection hole 3 b'. The end of the soil reinforcing material 3 A is connected to the connecting metal 4 A. At this time, a pull screw 7 may be provided on the soil reinforcing material 3A to adjust the verticality of the wall panel 2. (3) Furthermore, the soil is reinforced to the position where the metal piece 4 B is connected on the soil reinforcement material 3 A, and the soil layer 1 b is carefully rolled. (4) Then, the second layer of the soil reinforcing material 3 B is laid on the soil layer 1 b. The end of the soil reinforcing material 3 B is further connected to the connecting metal member 4. In the following, the second and third wall panels 2B and 2C and the supplementary soil reinforcements 3B and 3C are provided in the same manner as the complementary soil to constitute the entire reinforced soil structure. In the above-mentioned construction, especially when the supplementary reinforcement material 3 sinks due to the rolling of the supplementary soil, the end portion of the supplementary reinforcement material 3 may be directed downward along the connection hole 4 c connecting the metal pieces 4. The sliding prevents the stress from being concentrated on the connecting portion a of the wall panel 2 and the soil reinforcing material 3, so that the damage of the connecting portion a and the displacement and deformation of the wall panel can be reliably prevented. [Industrial application fields] · The wall panel of the present invention is constituted as described above, and in particular, the parts other than the part with the reinforcing bracket are formed to the thinnest, so it can save materials and reduce manufacturing. Cost can also achieve light weight and improve performance. _ In addition, because the soil-reinforcing material is connected to the metal parts [connection part] This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) -12- — 一-: ------- installation 1 ^ 1 (please read the note on the back to write this page) *?

Description of the invention (10) and a thick reinforced bracket, so for The strong earth pressure generated during the rolling of the supplementary soil layer can also be reliably resisted, and it is an extremely solid reinforcement reinforcement material. In addition, the connecting metal piece [connecting part] with a pulley function is protrudingly provided on a reinforcing bracket with a substantially rectangular plate-shaped wall panel as the left and right object and is continuously arranged in the vertical direction. The simple structure of left-right symmetry makes it difficult to generate undefined stress even if the soil-reinforcing material moves along the long hole of the connecting portion. Therefore, it is possible to form a solid and stable wall panel with the smallest connecting metal pieces. In addition, even if the sinking of the reinforcing reinforcement material occurs due to the sinking caused by the compression during the rolling or the sinking occurring over a long period of time, the ends of the reinforcing reinforcement material will be elongated along the slenderness. The connection hole slides downward so that stress is not concentrated on the connection portion between the wall panel and the reinforcing material. Therefore, it is possible to reliably prevent damage to the connection portion and displacement and deformation of the wall panel. In addition, since the wall panel is generally rectangular plate-shaped, with wide brackets at the edges of the left and right ends, and its wide brackets are convexly arranged at obtuse angles or substantially circular arcs, even for thin wall panels, No corner damage will occur. In addition, in the reinforced soil structure of the present invention, the wall panel itself maintains the mobility of the left and right spaces, and the compression in accordance with the vertical direction of the supplementary soil moves below the supplemental soil reinforcement material of the joint portion, so it can constitute a structure that is not easily damaged Strong reinforced soil construction.
