Bridge Engineering Application And Study On Clear Water Concrete Construction Technology

Clear water concrete construction Technology is directly by concrete nature appearanceeffect as decorative style. In last few years，With the country trend to transited fromdeveloping mode into infrastructure investment. City bridge especially city overpassengineering are also speed development. The civilization of the whole society，Architecturalaesthetics constantly sublimating，Building materials began tend to simplicity andnatural， Clear Water Concrete material just emerge at the right moment. Today is“low-carbon green”has become a philosophy of life of contemporary people， old concreteraw material and technology has not been adapted to the it. Result in city overpass bridgeengineering wide application to fair-faced concrete Construction Technology.In clear water concrete bridge engineering construction， Demanding strict onconstruction management，Demanding careful on construction process. In bridge engineering,the key to control the quality of the appearance is that clear Water Concrete have stabilityand durability，Bridge construction present completeness and appearance effect. The thesisbased on the experience that the author personally participates in Song Shan Nanlu bridgeengineering project, a mass of construction data is gained. Here is the analysis of the clearwater concrete technology application the bridge engineering project. There are several mainaspects are as follows:At first，completes deployment scheme about the begun preparation constructionactivities，Completes task about the preparation fair-face concrete technology，Solid itapplication the bridge foundation.Secondly，the key to research clear water concrete major construction technology， It ismainly discussed that the technological process three factors about the angle of engineeringquality requirements，the key technique of reinforcement engineering，the late age ofmaintenance concrete engineering，Clear water concrete bridge to ensure that they are in linewith quality requirement.Thirdly, Get the right fair-faced concrete mixture ratio to choose meet standard ofengineering raw material. By the massive of experimental contrast result about the fair-facedconcrete outer color and mixture performance, It is deeply discussed that the factors (the cement varieties content, coal ash content, admixture content, sand stone content and wateruse), To compare and calculate of the intensive grade C25,C30,C50’s fair-faced concrete,which final ensure the best approach of concrete.Fourthly，To attain bridge appear to look like smoothly and go though freely, To ensureeffective control in the construction details，Analysis of the outer quality acceptance standardabout the fair-face, During construction, Aim at the main influencing factor of the externalsurface quality. Take effective measures to avoid damage of the overall effect bridge.Finally, take the Zhengzhou city Song Shan Nanlu new bridge engineering constructionfor example, this prove that fair-faced concrete technology bridge in the actual construction,the some various reasons about the existence problems，Depend on accumulated that theauthor personally engineering experience，Puts out actual solutions deals with the problem offair-faced concrete bridge.The outer quality feel fine，the surface flat and smooth，uniform color，shiny anddazzling，looks like nature itself，All these present of natural marble texture and attain theeffect of fair-faced concrete. Practice has proved the project that the plan of fair-faceconcrete mix proportion, the measures of construction quality control and the schedule ofconstruction management are feasible. This research achievement can play a positive role inthe engineering bridges adoption of fair-faced concrete construction technology.
