{Form of Steel for Underground Passage Using Multiform}

The present invention relates to an underground passage wing steel wall formwork using a multi-foam, and more particularly, to a wing wall for preventing the inflow of gravelly matter by installing a wing wall formable on both sides of an underground passage.

Generally, underground passage is a structure that is constructed so that a vehicle or a person can pass safely under a highway, a national road, a local road or a railroad.

As a prior art for constructing such an underground passage, there have been proposed a registra- tion utility model No. 20-0253874 (name of a design: a steel form for a road crossing underground passage) and a registered patent No. 10-1540406 .

Among these prior arts, a steel form for a road crossing underground passage comprises a rail having at least a length equal to a passage width of an underpass structure and constituting a steel form for a road crossing underground passage structure; A die support rotatably coupled to the rails and arranged in a longitudinal direction; A hydraulic jack vertically installed on the die support and horizontally installed on both sides of the die support; An upper mold plate horizontally installed to be supported by the upper hydraulic jack to form a ceiling of the underground passage structure; A side mold plate hinged to both sides of the upper mold plate and connected to the side hydraulic jack inside to form a side wall of the underground passage structure; A lower mold plate hinged to a lower end of the side mold plate; And a lower hydraulic jack connected between the side mold plate and the lower mold plate to diffract the lower mold plate inwardly. Since the structure is made of a steel material, the structure is robust enough to cope with the concrete insertion pressure and can be recycled Since disposable wooden formwork is not used, disadvantages are expected for users and nationality. Therefore, it is possible to save a lot of cost and time when using a lease type, and since the disassembling / assembling is simple, It is also expected to be easy to use and easy to use.

In addition, prior art rock deformation formwork devices have been used to place concrete between the outer formwork assembly and the inner formwork assembly, to cure the inner formwork assembly from the cured concrete culvert, Since the side support plates are connected and the side support plates are separated from the side walls of the concrete culter by the rotational force (moment) of the side support plates and a little external force, it is easy to separate the side support plates from the cured concrete cullet, It becomes easy and quick. In addition, when the upper and lower side support plates of the inner die assembly are installed, the upper side support plate and the side support plates are connected by the hinge unit, thereby facilitating the installation work.

However, since the formwork of the prior art for constructing the underground passageway and the culvert is not equipped with the anti-slip dock formwork, the formwork is individually assembled and assembled at the site every time the work is performed, The wing wall could not be constructed and the appearance was deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the conventional art, and it is an object of the present invention to provide an underfloor, Which is configured to construct a wing wall for blocking an underground passageway wing wall.

In order to achieve the above object, a wing wall formwork for constructing a gravel-blocking wall is installed on both sides of an underground passage constructed as a concrete structure so that a passageway space is formed on the inner side, A front panel on which a side plate is detachably fastened; A rear panel spaced apart from the front panel and being detachably coupled to rear surfaces of both sides of the underground passage; A lower horizontal finishing panel in which front and rear panels are detachably and horizontally fastened between a rear plate and a bottom plate of the front and rear panels, and a side plate is detachably fastened to both sides of the underpass; A lower angle adjusting panel rotatably connected to the side plates of the lower horizontal finishing panel so as to be rotatable and being detachably fixed by a fixing member between a rear plate and a front plate of the front and rear panels; A plurality of inclination adjusting devices mounted horizontally and vertically below the front panel of the front panel, the front panel of the rear panel, and the lower angle adjusting panel to adjust the inclination angle of the lower angle adjusting panel; And an upper vertical finishing panel in which a lower panel and a side panel are removably fastened and fixed between the upper panel of the lower angle adjusting panel and the front panel of the front panel and the front panel of the rear panel, .

According to the present invention, a wing wall form can be detachably mounted on both sides of a front surface of an underground passage, so that a standardized wing wall for preventing the entrance of gravel to the front surface of an underground passage can be easily installed. In addition, the angle of the lower surface can be selectively adjusted, thereby providing an excellent compatibility.
