Research And Implementation Of Durability Detection And Assessment Of The North Gravity Wharf

There are the kinds of problems after the completion of the pier. Some are not inuse，existing crack, corrosion, freezing and thawing and other damage；Some in theprocess of using the concrete deterioration, failure problems such as anticorrosionmeasures，results in the decrease of durability of concrete structure. Then re-enabledbefore the pier or the continued use of the pier are required durability can be detectedand assessed.In recent years, due to the rapid expansion of port capacity, department oftransportation to enhance our ongoing ability to berth alongside the pier constructionreinforcement structure. before the design scheme is put forward, the detection andevaluation of the durability of the wharf structure is an important content.Assess the durability of concrete piers mainly based on physical properties,durability testing direct conclusions can be derived from the use of certain analyticalmethods to assess the durability of concrete structures on the pier were graded.The current watertransportation industry standards have the rules on the northdurability testing and evaluation method, but slightly on specific parameters andtesting number conflict,is not comprehensive enough For concrete resistance tochloride ion penetration and freeze-thaw resistance detection method,and to improvethe test accuracy and test efficiency also has shortcomings.In this paper, combining the current, water transport, railway standard provisionsof the state, to the north of gravity wharf number from the test parameters, test method,evaluation method and so on has carried on the summary and supplement, it makesthe north pier evaluation system to assess the durability of concrete detectiontechnology based on more comprehensive, more maneuverability.In this paper, the test evaluation system has been validated in rizhao port, west12berth,it can become the durability of the pier reinforcement and reconstruction.
