Method for reinforcing existing structure by spraying UHPC (Ultra High Performance Concrete)
The invention relates to the technical field of building construction, in particular to a method for reinforcing an existing structure by spraying UHPC. The method comprises the following steps that S1, the to-be-reinforced surface of the existing structure is cleaned, and anchor bars with hooking structures are implanted into the cleaned to-be-reinforced surface; s2, an injection pipe is installed, UHPC is injected to the to-be-reinforced surface through the injection pipe, and after the to-be-injected UHPC reaches the set thickness, injection is stopped; s3, a reinforcing mesh is manufactured, the reinforcing mesh is hung on the anchor bars, and the reinforcing mesh is fixed through a hooking structure; s4, the UHPC is sprayed to the surface to be reinforced again till the required thickness is achieved; and S5, the steps from S2 to S4 are conducted in sequence till the surface to be reinforced is reinforced, the reinforced surface is corrected and maintained, and reinforcement of the existing structure is completed. The reinforcing method for the existing structure is extremely simple and extremely convenient to operate, the reinforcing effect on the existing structure is extremely good, the reinforcing strength is guaranteed, and the dead weight of the existing structure cannot be greatly increased.
本发明涉及建筑施工技术领域，具体地指一种采用喷射UHPC加固既有结构的方法。按照以下步骤进行：S1、对既有结构的待加固表面进行清理，在清理后的待加固表面植入带有钩挂结构的锚筋；S2、安装喷射管，利用喷射管向待加固表面喷射UHPC，待喷射的UHPC达到设定厚度后，停止喷射；S3、制作钢筋网，将钢筋网挂在锚筋上，通过钩挂结构对钢筋网进行固定；S4、再次向待加固表面喷射UHPC，直至达到所需厚度；S5、按照S2～S4的步骤依次进行，直至完成对待加固表面的加固，修正加固表面并进行养护，完成对既有结构的加固。本申请对于既有结构的加固方法极为简单，操作极为方便，对既有结构的加固效果极好，加固强度有保证，不会大幅度增加既有结构的自重。
