Problems solved by technology
[0013] In addition, the water stop member should be closed in a ring shape according to the end face shape of the concrete underdrain. When the water stop member is closed and the butt welded seam is performed, the elongated structure formed in the center of the water stop member will be squeezed if not careful. Welding, and large interferences can cause problems where butt welded seams are practically impossible to achieve

Embodiment Construction
[0038] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is described with reference to the embodiment shown in the accompanying drawings, however, this is only illustrated as an example, and the technical idea, core structure and function of the present invention are not limited thereto.
[0039] First, if figure 1 and figure 2 As shown, the corrugated hollow closed water-stop plate 1 according to an embodiment of the present invention can be fixedly installed on the joint surface of a box-shaped underdrain 10a on one side. The corrugated hollow closed water-stop plate 1 is composed of horizontal plate parts, and has the following structure formed by extruding synthetic resin materials: a hollow corrugated part 102 in the central part and two corrugated parts in the hollow corrugated part 102 respectively. The first plate-shaped part 101 and the second plate-shaped part...

A concrete culvert using a corrugated hollow closed water stop and a construction method thereof, according to one embodiment of the present invention, enables: a hollow corrugated part to be inserted, in a close state, into an expandable groove, which is a part of a joining groove, by using the corrugated hollow closed water stop having the hollow corrugated part formed on a culvert unit joining surface so as to not be partially filled with a grout material and thus to be adaptively expandable according to crack behavior of a concrete culvert; the hollow corrugated part to be easily inserted and set into concave parts of first and second concrete culvert units by itself without resistance through the use of a plate-shaped part of the corrugated hollow closed water stop; and the number of grout material injection paths and outputs to be reduced since the grout material can move along the first and second plate-shaped parts, and thus the present invention is economical and a complicated construction method can be simplified.
Description
technical field [0001] The invention relates to a corrugated hollow closed water stop board, a concrete underdrain structure using the water stop board and a construction method thereof. More specifically, it relates to a wave-shaped hollow closed water-stop plate (hereinafter referred to as “wave-shaped closed water-stop plate”), a concrete underdrain structure using the water-stop plate, and a construction method thereof. The edge of the wave-shaped closed water-stop plate The corner portions can be closed in a ring shape according to the shape of the end face of the concrete underdrain without using other connection means and can be butt-welded to each other, so that the watertight joint between adjacent concrete underdrains can be made durable. Background technique [0002] For the concrete underdrain structure (hereinafter referred to as "underdrain structure") formed by connecting multiple precast concrete underdrains (hereinafter referred to as "concrete underdrains")...
