DESIGN FOR corrugated metal culverts

摘要

The invention relates to the field of pipe systems and can be used, for example, in the construction and reconstruction of destroyed small and medium-sized bridges and culvert systems. Corrugated metal culverts design for large-block is formed from prefabricated elements with two flanges and longitudinal openings. Krupnoblochnogo elements are in the form of arcs, a compound formed along the tube axis between an individual sheet of metal corrugated circumferential segments. Along the edges of the corners of the arches are fixed. The longitudinal displacement of one of the corners of the sheet with respect to the segment edge is not less than 1/3 of the width of the sheet segment of a circle. Connecting two or more coarse-arch elements forms a single closed structure of the metal corrugated tube. At the input and output portions of the metal corrugated pipes vertically mounted flanges. The upper edges of flanges formed mounting holes. Flanges formed with a width and a height of not less than 1.3 times the outer diameter of the corrugated metal pipe. On the inner side of the flanges on the lower level of metal corrugated tubes are arranged connecting elements. The connecting elements are designed as combining parts from the plates. On uniting parts and the plates on the one hand vertically mounted pins, and the other holes for pins are made. The plates are made with a pin length of at least the magnitude of the inner radius of the metal corrugated tube. 1 n.p.f. 5 yl.
