Problems solved by technology

[0004] In the prior art, when building an arch bridge, it is necessary to carry out follow-up construction based on the topography of the construction site, and a support structure needs to be built during the construction process, and the support structure needs to ensure its strength in order to ensure the construction of the arch bridge. Therefore, in the construction process In the middle, the supporting structure will be deformed due to terrain problems, which will affect the effect and progress of arch bridge construction

Embodiment 1

[0052] Obtain construction environment data, in the present invention, obtain the building position information of arch bridge in the construction environment respectively; Obtain the load information of arch bridge after construction; Specifically can obtain the aerial photograph picture of construction environment by the mode of aerial photography, and aerial photograph picture is converted into electronic drawing , and analyze the drawings to form digital data for storage; in the present invention, to obtain the use environment data, in addition to obtaining the information of the construction environment film, it is also necessary to obtain the climate information of the construction site; it is necessary to predict the follow-up data in combination with the climate;

[0053] Of course, the load information of the arch bridge after construction is obtained according to the obtained construction environment information; that is, the passing capacity of the bridge is predicted...

Embodiment 2

[0070] Obtain the load information of the arch bridge after construction according to the obtained construction environment information; that is, predict the passing capacity of the bridge to ensure the use of the bridge after completion;

[0071] Specifically, the load information is obtained by the following formula:

[0072] in,

[0073] N is the passing capacity of a single trunk line; the unit is cubic meters;

[0074] V is the driving speed of the vehicle; combined with the actual traffic situation, take 25km / h;

[0075] N is the number of traffic lanes; among the present invention, go two-way lane, the number of traffic lanes taken is 1;

[0076] S is the inter-vehicle distance; according to the actual data acquisition, take 50m;

[0077] Kh is an imbalance coefficient, and the value range is 0.5~0.7; Considering factors such as equipment maintenance and climate, 0.5 is taken in the present invention;

[0078] It can be obtained from this: N=(1000*25*1) / 50*0.5=250...

Abstract

The invention provides a construction method of a corrugated steel arch bridge. The construction method comprises the following steps: acquiring construction environment data; performing modeling according to the obtained data; building a corrugated steel support structure according to the modeling data; building an arch bridge on the built corrugated steel supporting mechanism; according to the construction method of the corrugated steel arch bridge, data are reasonably used for building the arch bridge, the building effect of the arch bridge can be guaranteed, and the building progress of the arch bridge is improved.

Description

technical field [0001] The invention relates to the technical field of arch bridges, in particular to a construction method of a corrugated steel arch bridge. Background technique [0002] An arch bridge refers to a bridge that uses the arch as the main load-bearing member of the structure in the vertical plane; in the construction process of the arch bridge, it is necessary to build the supporting structure of the arch bridge and culvert first, and then carry out the construction of the arch bridge on the completed supporting structure. There will be arch culverts in the completed arch bridge; among them, [0003] The arch culvert is actually a kind of channel, which is used for water or people and vehicles to pass under the arch culvert, and uses the good compressive performance of the arch structure to improve the stability of the arch bridge; [0004] In the prior art, when building an arch bridge, it is necessary to carry out follow-up construction based on the topogra...
