1.混凝土结构加固方法与技术混凝土结构的加固分为直接加固与间接加固两类,设计时可根据实际条件和使用要求选择适宜的方法和配套的技术。直接加固的一般方法有:1.1加大截面加固法该法施工工艺简单、适应性强,并具有成熟的设计和施工经验;适用于梁、板、柱、墙和一般构造物的混凝土的加固;但现场施工的湿作业时间长,对生产和生活有一定的影响,且加固后的建筑物净空有一定的减小。1.2置换混凝土加固法该法的优点与加大截面法相近,且加固后不影响建筑物的净空,但同样存在施工的湿作业时间长的缺点;适用于受压区混凝土强度偏
1. Reinforcement methods and techniques for concrete structures Reinforcement of concrete structures is divided into two types: direct reinforcement and indirect reinforcement. The appropriate method and supporting technology can be selected according to actual conditions and application requirements. The general methods of direct reinforcement are: 1.1 Increasing section reinforcement method This method has simple construction process, strong adaptability, and has mature design and construction experience; it is suitable for concrete reinforcement of beams, slabs, columns, walls and general structures; However, the on-site construction of wet operation for a long time has a certain impact on production and life, and the building clearance after reinforcement has a certain reduction. 1.2 Replacement Concrete Reinforcement Method The advantages of this method are similar to that of the enlarged section method, and it does not affect the building clearance after reinforcement, but it also has the disadvantage of long wet construction time; it is applicable to the concrete strength of the compression area.
