Description

  The present invention relates to a portal block manufacturing form in which a required width and left and right channel walls can be formed at an arbitrary angle.

FIG. 12 (a) shows a gate-shaped block 10 that is frequently used for a conduit or connected to the top and bottom in civil engineering work, and is shown in FIG. 12 (b). Is a culvert block 20 connected to However, in the conventional gate-form block manufacturing form, few widths can be adjusted, and the right and left water channel walls 11 and 12 are perpendicular to the end portions 10F and 10R in a plan view (hereinafter, the angle of the water channel wall). Means an angle in plan view with respect to the end portions 10F and 10R) .

For the above reasons, at the construction site where the waterway and the road or the road and the road intersect three-dimensionally, the gate-shaped block 10 or the culvert block 20 connected to the top and bottom is hidden under the road or the like. In the site other than the extension line C1 indicated by the alternate long and short dash line in the figure and the road etc. are orthogonal to each other, the front end portion 10F, the rear end portion 10R, etc. It is often desirable to add an angle to the required position. Usually, a partition plate with the required angle is created at a predetermined position on the front and rear ends of the portal block manufacturing formwork, and is temporarily attached by electromelting. In many cases, the end blocks 10F and 10R before and after the portal block 10 manufactured in the manufacturing process are cut with a wire saw or the like (indicated by a broken line in the figure) and delivered. Answer to processing request However, it was not possible to form the right and left water channel walls 11 and 12 of the portal block 10 at an angle from the initial stage of manufacture.

There is a patent document described below as a form for manufacturing a water channel block corresponding to a product having different required water channel width, water channel wall thickness, water channel depth, etc. by exchanging or adjusting members.
