摘要:
运煤栈桥是大型矿场和燃煤电厂的重要运输设施,而混凝土的碳化对运煤栈桥的使用寿命有着极大的影响,对其进行科学的耐久性评估和使用寿命预测有着重要的意义.对陕北地区某栈桥的气候环境、工作环境、外观质量、混凝土强度、混凝土碳化深度及混凝土保护层厚度耐久性参数进行了调查与检测,基于检测结果,分析了运煤栈桥的主要病害及结构性能劣化原因,并预测了栈桥的剩余寿命,为栈桥的正常运营及维护加固提供了科学依据.
Abstract:
A trestle of transportation coal is an important facility to large mines and coal-fired power plants. Concrete carbonation  has a great impact on the service life of trestle, and the evaluation of durability and the prediction of life is extremely significant to structure of the trestle. The durability of the coal trestle, including climate environment, work environment, the visual quality, concrete strength, concrete carbonation depth and concrete cover thickness, was inspected and tested and the results of the inspection and testing were all analyzed in this paper. The main disease and the reason of deterioration of the trestle were analyzed based on the result of testing, and the remaining life of the trestle was predicted. The research provides the scientific basis for maintenance and reinforcement of the trestle.
