Embodiment approach 1
[0061] A corrugated steel sheet for corrugated steel arch bridge culverts, such as figure 1 As shown, the corrugated steel plate used for the corrugated steel plate arch bridge culvert includes a corrugated steel plate main body 1, two end steel connecting plates 2-1, 2-2.
[0062] The two end steel connecting plates 2-1, 2-2 are rectangular steel plates with the same shape and size, the width of the rectangle is greater than the wave height of the corrugated steel sheet main body 1, and two end steel connecting plates 2-1, 2-2 are provided with two There are a total of n through holes in a row.
[0063] In the middle of the two wide sides of the corrugated steel sheet main body 1, a piece of end steel connecting plate is vertically welded respectively, and the width of the corrugated steel sheet main body 1 is l 2 The length l of the end steel connecting plate 3 Half a wavelength l at each end of 4 .

[0102] In engineering cases, l 0 = 15m, L = 6m, l 1 = 2m, l 2 = 1.7m, l 3 = 1.5m, l 4 = 0.1 m.
[0103] Step 1 calculates the number of rows N of corrugated steel plates used for corrugated steel plate arch bridges and culverts for building corrugated steel plate arch bridges and culverts:
[0104] N=15 / 2=7.5m
[0105] Calculate the number M of corrugated steel sheets for each row of corrugated steel arch culverts:
[0106] M=6 / 1.5=4m

Abstract
The invention provides corrugated steel sheets for corrugated steel arch bridges and culverts and a bridge and culvert installation method utilizing the same, relating to corrugated steel sheets and solving the following problems in the installation methods of the existing sheets for corrugated steel bridges and culverts: the overall mechanical performances of the sheets are unreasonable, the connecting bolts bear large shearing force and the reliability is low. Each corrugated steel sheet comprises a corrugated steel sheet main body (1) and two end steel connecting sheets (2-1, 2-2) vertically welded on the two wide sides. The method comprises the following steps of: cutting the long sides of the first row of corrugated steel sheets connected with first and second arch abutments (D-1, D-2) and the wide sides of the corrugated steel sheets at the end of each row, installing the corrugated steel sheets for the corrugated steel arch bridges and culverts from the first tips to the second tips of the first and second arch abutments in sequence, installing the second row of corrugated steel sheets for the corrugated steel arch bridges and culverts in sequence above the first row and lapping the third row on the second row until cloture, wherein the first row of corrugated steel sheets and the second row of corrugated steel sheets are connected by bolts and nuts. The arch bridges and culverts have high reliability and construction convenience.
Description
technical field [0001] The invention relates to a corrugated steel sheet of a corrugated steel bridge culvert and a bridge and culvert installation method thereof. More specifically, the present invention relates to a structure form of corrugated steel plates, and adopts a corrugated steel plate arch bridge culvert installation method to ensure and improve the convenience and reliability of the corrugated steel plate arch bridge culverts. Background technique [0002] The corrugated steel plate arch bridge culvert is a structure that uses corrugated steel plate as the main load-bearing component. The corrugated steel plate and roadbed filler are used to form an arched structure to jointly bear the external load. It has strong anti-seismic ability, can adapt to the settlement deformation of alpine climate, and can be applied to roadbeds with various filling heights. Compared with reinforced concrete and masonry, it has the advantages of convenient construction, short constru...
