Embodiment 2

[0040] The construction method of the present embodiment round arch bridge is the same as embodiment 1, and its difference is that this round arch bridge needs to be divided into the number of section arch section bar of section number and the setting long connector and hull supporting frame by actual bridge and form.

[0041] The arch profile is composed of 81kg of carbon steel, 36kg of engineering plastics, 12kg of dodecyl methacrylate, 15kg of ammonium lauryl sulfate, 6kg of tetradecyl thioacetic acid, 2-acetamido 14kg of ethanol, 7kg of 2-allyl methacrylate, 13kg of 2-acrylic acid, and 6kg of (Z)-oxocyclohexadec-8-en-2-one are produced by rolling, extrusion, and casting processes.

[0042] The hull support frame is composed of 72kg of low-alloy corrosion-resistant steel, 4kg of 2-ethyl-1-hexanol, 7kg of isobutyl acrylate, 3-(N,N-dimethyldodecyl Ammonium) propanesulfonate 4kg, 3,4,5-trihydroxy-1-cyclohexene-1-carboxylic acid 8kg, 4-ethylcyclohexanol 9kg.

Embodiment 3

[0044] The construction method of the present embodiment round arch bridge is the same as embodiment 1, and its difference is that this round arch bridge needs to be divided into the number of section arch section bar of section number and the setting long connector and hull supporting frame by actual bridge and form.

[0045] The arch profile is composed of 84kg of carbon steel, 38kg of engineering plastics, 14kg of dodecyl methacrylate, 17kg of ammonium lauryl sulfate, 4kg of tetradecyl thioacetic acid, 2-acetamido 15kg of ethanol, 9kg of 2-allyl methacrylate, 11kg of 2-acrylic acid, and 7kg of (Z)-oxocyclohexadec-8-en-2-one are produced by rolling, extrusion, and casting processes.

[0046] The hull support frame is composed of 60kg of low-alloy corrosion-resistant steel, 6kg of 2-ethyl-1-hexanol, 5kg of isobutyl acrylate, 3-(N,N-dimethyldodecyl Ammonium) propanesulfonate 5kg, 3,4,5-trihydroxy-1-cyclohexene-1-carboxylic acid 10kg, 4-ethylcyclohexanol 7kg.

Abstract

The invention belongs to the field of buildings and particularly relates to a circular arch bridge. The circular arch bridge comprises arching profiles, connecting pieces and a ship bracket, wherein the arching profiles and the connecting pieces are divided by section according to actual circular arch bridge needs. The arching profiles are manufactured from carbon steel, engineering plastics, lauryl methacrylate, ammonium lauryl sulfate, tetradecylthioacetic acid, 2-acetamido ethyl alcohol, 2-allyl methacrylate and the like through rolling, extrusion and casting processes. The ship bracket is prepared from low alloy corrosion resistant steel, 2-ethyl-1-hexanol, isobutyl acrylate, 3-(N,N-dimethyl dodecyl ammonium) propane sulfonate and the like. The circular arch bridge breaks through the ultimate strength of existing bridges, is high in strength and tolerance and long in service life, meets current social development needs and accords with sustainable development national conditions of China. The bridge is easy and convenient to construct, manpower and material resources are greatly saved, bridge building cost is reduced, and rapid construction of the infrastructure can be conveniently promoted.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a round arch bridge. Background technique [0002] A bridge is a structure built for roads to cross natural or man-made obstacles, for example, bridges across rivers and ravines. According to different purposes, bridges can be divided into road bridges and railway bridges. [0003] In recent years, with the development of railway transportation and road transportation, higher requirements have been put forward for the strength of bridges. Taking railway transportation as an example, in order to improve the transportation capacity of railway transportation, heavy-haul railway transportation has been produced. The so-called heavy-duty railway transportation refers to the transportation method that uses high-power locomotives to pull heavy-duty trains under certain railway technical equipment conditions. [0004] Compared with the past few years, the current traffic flow...
