Method and system for quickly improving bonding strength of concrete repairing interface in short time
The invention belongs to the field of concrete repairing, and particularly relates to a method and system for rapidly improving the bonding strength of a concrete repairing interface in a short time. The method for quickly improving the bonding strength of the concrete repair interface in a short time comprises the following steps: pouring a repair material on an existing concrete repair surface in a layered manner; wherein each layer of repairing material is provided with a power-on network formed by fibers; the fiber sizes of all layers of electrified networks are different; after the to-be-repaired material is poured, a positive electrode metal wire mesh and a negative electrode metal wire mesh are inserted into the to-be-repaired material; the positive electrode metal wire mesh and the negative electrode metal wire mesh penetrate through all the repairing layers and are in contact with the repairing surface of the existing concrete matrix; the positive electrode wire mesh and the negative electrode wire mesh are electrified, gradient heat is generated in each layer of repairing material, and high bonding performance is achieved on a repairing interface in a short time.
本发明属于混凝土修复领域，尤其涉及一种短期快速提升混凝土修复界面粘结强度的方法及系统。其中，短期快速提升混凝土修复界面粘结强度的方法包括在既有混凝土修复表面分层浇筑修复材料；其中，每层修复材料均具有纤维构成的通电网络；各层通电网络的纤维尺度不同；待修复材料浇筑完成后，在修复材料中插入正极金属丝网片和负极金属丝网片；正极金属丝网片和负极金属丝网片均贯穿浇筑所有修复层，且与既有混凝土基体修复表面接触；将正极金属丝网片和负极金属丝网片通电，在各层修复材料中产生梯度热量，以短期在修复界面实现高粘结性能。
