Description

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

  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, there are few prior art portal block manufacturing forms that can adjust the required width, and the left and right water channel walls 11 and 12 can only be a right-angle product in plan view.

  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. At sites other than where the extension line C1 in the figure and the road etc. are orthogonal to each other, in order to improve the field of view, the profit is not taken into account and the angle is set at the required positions such as the front end portion 10F and the rear end portion 10R of the gate block at the manufacturing plant. It is often desired to attach a partition plate of the required angle to a predetermined position on the front and rear ends of a portal block manufacturing formwork, and it is temporarily attached by electromelting, or it is normally manufactured In many cases, the end 10F, 10R of the block 10 before and after the desired one is cut and delivered with a wire saw or the like, and the demand for the end processing is answered by such a complicated method. From gate to gate It could not be formed at an angle to the right and left water channel walls 11, 12 of the lock 10.
