Problems solved by technology

[0006] But the structure is complicated: the steel bars are leaning outward and dense, space positioning is difficult, the formwork is outwardly leaning and the operation space in the mold is small, and there are many embedded parts on the top of the pier
[0007] The traditional construction method is that the main reinforcement of the pier body is lengthened one by one on site, the horizontal stirrups are bound layer by layer, the formwork of the standard section and the curved section of the pier body are installed in stages, and the concrete is poured in stages. Appearance and quality defects such as seams and protective layer pass rate are low

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] The construction method provided by the invention has the characteristics of fast construction, reasonable structure, economic benefits, etc., and is widely applicable to urban high-pier bridges, especially urban high-pier landscape bridges.

[0022] The technological principle of the construction method provided by the present invention is as follows: steel pipe scaffolding is erected around the pier body as a working platform for installation of the pier body reinforcement skeleton, formwork installation and dismantling, and concrete pouring. Installed as a whole, the formwork of the pier body is assembled in sections using shaped steel formwork in the form of a pier body curve.

[0023] The operation plan of the present invention is: 1. The pre-embedded main reinforcement of the pier column is positioned and welded firmly with the reinforcemen...

Abstract

The invention discloses a construction method for pouring and forming an urban viaduct curve type pier stud in a one-off mode. The construction method includes the following steps of 1 positioning pier stud pre-buried main reinforcement, 2 chiseling the combined portion of a pier body and a pile cap, 3 staking out in survey, 4 putting up a scaffold, 5 machining and installing reinforcement, 6 machining and installing a formwork, 7 pouring concrete, 8 disassembling the formwork and curing, and 9 removing the scaffold. According to the construction method for pouring and forming the urban viaduct curve type pier stud in the one-off mode, the pier stud has the advantages of being fast to construct, reasonable in structure, economical, practical and the like and is widely applicable to an urban high-pier bridge, particularly an urban high-pier landscape bridge.

Description

technical field [0001] The invention relates to a construction method of a viaduct, in particular to a construction method of one-time casting and forming of curved pier columns of an urban viaduct. Background technique [0002] With the rapid development of economy and urban traffic, the bridges in viaducts gradually require "landscape", and the shaping of the image of the city or region by the bridge landscape is also more and more concerned by people, and it must match the shaping of the image of the city or region . [0003] Compared with beams, piers are closer to people's point of view. The shape, volume, surface treatment and appendages of pier columns all form landscape elements and are the focus of aesthetic design. [0004] In recent years, bridge piers have also developed from early cylindrical piers to slender and beautiful light-weight piers, especially curved piers are widely used in China. [0005] The curved piers have strong applicability and beautiful app...
