Embodiment approach 1

[0061] A corrugated steel sheet for corrugated steel arch bridges and culverts, such as figure 1 As shown, the corrugated steel sheet used for the corrugated steel arch bridge and culvert comprises a corrugated steel sheet main body 1 and two end steel connecting plates 2-1 and 2-2.

[0062] The two end steel connecting plates 2-1 and 2-2 are rectangular steel plates with the same shape and size, and the width of the rectangle is larger than the wave height of the corrugated steel plate The row has n through holes in total.

[0063] A piece of end steel connecting plate is vertically welded to the middle of the two broad sides of the corrugated steel sheet main body 1. The width l of the corrugated steel sheet main body 1 is 2 Grow the length l of the steel connecting plate at the end 3 The two ends of each half wavelength l 4 .

[0102] In engineering cases, l 0 = 15m, L = 6m, l 1 = 2m, l 2 =1.7m, l 3 =1.5m, l 4 =0.1m.

[0103] Step 1: Calculate the number of rows N of corrugated steel sheet used for corrugated steel arch bridges and culverts used in the construction of corrugated steel 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 bridges and culverts:

[0106] M=6 / 1.5=4m

[0107] In step 2, the long-side cutting method of the two first rows of corrugated steel plate sheets directly connected to the first and second arch platforms D-1 and D-2 for corrugated steel plate arch bridges and culverts is as follows:

[0108] The fractional part n of N resulting from the calculation 0 < 0.6, the corrugated steel sheet used for the corrugated steel arch bridge and culvert is cut to 1.5m along the direction perpendicular to the long side;

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 plate sheet of a corrugated steel plate bridge and culvert and a bridge and culvert installation method thereof. More specifically, the present invention relates to a corrugated steel plate sheet structure, and adopts a corrugated steel plate arch bridge and culvert installation method to ensure and improve the convenience and reliability of the corrugated steel plate arch bridge and culvert. Background technique [0002] The corrugated steel plate arch bridge and culvert is a structure with corrugated steel plate as the main bearing member. The corrugated steel plate and the roadbed filler are used to form an arch structure to jointly bear external loads. It has strong anti-seismic ability, can adapt to the settlement and deformation of alpine climate, and can be applied to roadbeds with various filling heights. Compared with reinforced concrete and masonry masonry, it has the advantages of convenient const...
