The present invention provides a technique for manufacturing a prefabricated retaining wall block using a prefabricated retaining wall block formwork which prevents the occurrence of fatal cracks in the block due to traffic restrictions and excessive impact during transportation.

       Conventionally, a retaining wall using reinforced concrete forms a footing and a wall integrally to support the back soil pressure of a retaining wall installed on an inclined surface, thereby casting concrete to secure activity, conduction, and supporting force, and to maintain a cross section of the retaining wall. However, the reinforced concrete retaining wall has to go through reinforcement assembly, form assembly, scaffold installation, concrete placing, curing, etc. by reinforcing steel reinforcement and concrete casting in the field. There are problems of environmental pollution due to noise and dust caused by external weather and construction, and concrete installation for installation of retaining wall. In winter, construction has been stopped due to freezing.

       In order to overcome the above problems, we have been using the technology of prefabricating walls and foundations when installing retaining walls.

       When assembling and installing the retaining wall using the above technology, the formwork should be manufactured to manufacture the block, but the size of the retaining wall block varies, so to satisfy all of these, the form of the mold of various specifications should be produced to produce the block. It is a problem that the manufacturing cost is increased exponentially, and it is not used in reality at present, and the technology for the "retaining wall frame" filed with the utility model registration on September 5, 2003 under application No. 20-2003-28621 As shown in (a) (b) of Figure 1, in the case of Figure (a), the side plate is installed on the mold base 100 and the side plate moving member 110 is installed and the side plate moving member 110 Blocks of various standards by installing the anchor mounting device 600 while installing a vertical frame on the inner end of the side plate moving member 110 while installing the first side plate unit 210 on the top In order to induce the side plate movement by moving the plate moving member 120 installed below the mold base 100, and to adjust the thickness of the first side plate unit up and down to adjust the thickness, Figure (b) In the case of), a pair of mounting board units are installed, a wall joint unit 840 is installed at one side, and a mounting board unit is installed at the other side, and a wall ceiling unit 850 is installed therein to produce various walls. As shown in Figs. (A) and (b), when manufacturing the retaining wall using the mold, it is necessary to operate the plurality of devices to manipulate the size of the retaining wall mold, so that the retaining wall can be manufactured. It is not easy to assemble and install near the site, and it is not easy to make a block easily by using it, and a large number of related devices when making a block by using a mold It is a hassle to operate all of them, and the production cost of the mold and the hassle of manipulating it are accompanied by the increase of construction cost according to the production and the hassle that an experienced operator must perform to manufacture and install the mold and produce it using the same. There is a problem that the retaining wall can be produced only through a complicated manufacturing step.

On the other hand, the prior art Figure 1 is to install the retaining wall of a large number of devices in order to manufacture a retaining wall of a variety of standards, while manufacturing the retaining wall after operating these devices when manufacturing the retaining wall corresponding to each standard, In order to manufacture the retaining wall, formwork is installed on the site and the device is Produced by a single retaining wall after groping then again to produce a mold of a different size must go through the cumbersome process of making a retaining wall after the operation a large number of devices will be produced in the retaining wall,

       Even in the case of manufacturing using the above apparatus, the present invention simply installs steel in a rectangular parallelepiped shape in order to manufacture the wall and the foundation block, and in the case of the wall block in order to vary the size of the block, only the bottom plate is the basic block. In order to manufacture the prefabricated retaining wall simply by replacing only the foundation block top plate formwork and casting concrete, Figure 1 of the prior art installs a large number of devices related to the retaining wall form to retaining wall form and different specifications Each time a retaining wall is manufactured, there is a difference in that manufacturing has always been involved in manufacturing the retaining wall after operating all related equipment.
