Guangzhou X Bridge Pier Strengthening Construction Technology Management

Nearly20years research on the properties of bridge pier column has been a hotissue.Existing a large number of existing urban Bridges due to the unreasonable earlydesign specification, structure, function change, construction defects and damage in theprocess of long-term use, aging caused by poor seismic performance, bearing capacityis insufficient, and many other affect their safety and use function problem is verycommon, continue to use it is necessary to adopt practical and effective method fortheir reinforcement and reconstruction for reinforcement.Through maintenance cityBridges, can prevent and avoid the city bridge collapse caused economic loss andpersonnel casualties, city bridge maintenance, not only can prolong the service life ofexisting Bridges, use less as far as possible funding, restore the urban bridge trafficdemand, also can delay the concentration of urban bridge construction investment,bring huge economic benefits and social benefits to the nation.Briefly introduced in this paper, the existing various methods, combined withsouth China road3period yongtai interchange mainspan T compose pier reinforcementproject, to focus on the commonly used method has carried on the comparison, theintegrated use of several strengthening technology, in the process of implementation, inthe process of strengthening technology, environmental protection, quality, safety,civilization and progress is introduced in detail.Old bridge reinforcement engineering is a complex, system engineering, need todevelop the corresponding specification of urban bridge reinforcement, and should setup a professional maintenance company, specializing in city bridge maintenancemanagement, design and construction of the reinforcement engineering.With thedevelopment of various new materials, new construction technology and the use of new materials, makes the bridge maintenance objects, broader construction moreconvenient and quick.By south China road3period yongtai interchange mainspan Tcompose the implementation of the pier reinforcement project, solve the practicalproblems encountered in engineering, and considerable economic benefit and socialbenefit, has great popularization value.
