Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] A concrete construction process in form-turning construction of a high pier without support, comprising step A: concrete raw material, step B: concrete mixing ratio, step C: concrete mixing, step D: concrete transportation, step E: concrete pouring, step F: Section 1 Concrete Strength and Step G: Curing.

[0016] Step A: Concrete raw materials, the quality of various raw materials and mixtures used for concrete mixing have been inspected and are in compliance with the provisions of the current "Test Regulations for Cement Concrete in Highway Engineering" (JTJ053).

[0017] Step B: Concrete mix ratio, the concrete mi...

Abstract

The invention discloses a concrete construction technology in high-pier non-bracket turnover formwork construction. The concrete construction technology comprises the steps of 1 concrete raw material preparing; 2 concrete mixing proportion setting; 3 concrete blending; 4 concrete transporting; 5 concrete pouring; 6 first-segment concrete intensity forming; 7 maintaining. According to the concrete construction technology in high-pier non-bracket turnover formwork construction, the significant superiority and scientificity are achieved, and compared with support construction, the advantages that labors and materials are saved, and the speed is high are achieved, and the construction safety coefficients are increased while the good economic benefit is created.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a concrete construction technology in the formwork construction of a high pier without support. Background technique [0002] In recent years, the expressways in western my country have developed rapidly, and the highway construction has begun to extend to mountainous areas. However, in these areas, the mountains are steep, the height difference is large, and the site is narrow, which makes a large number of high pier structures used in bridge construction. The commonly used support construction requires a large number of scaffolds, which not only consumes a lot of manpower and material resources, but also has complicated procedures, slow progress, and low safety factor. Contents of the invention [0003] The object of the present invention is to provide a concrete construction technology in the formwork construction of high pier without support, which has solved the pro...
