Method for quickly and nondestructively reinforcing existing structure through UHPC (Ultra High Performance Concrete)
The invention discloses a method for rapidly reinforcing an existing structure in a lossless mode through UHPC. The method comprises the following steps that S1, light UHPC anchor blocks are prefabricated; s2, the to-be-reinforced surface of the existing structure is cleaned and wetted, high-viscosity UHPC is sprayed, spraying is stopped after the preset thickness is achieved, and a bonding layer is formed; s3, a light UHPC anchor block is installed on the bonding layer before initial setting of the bonding layer; s4, early-strength UHPC is sprayed to the to-be-reinforced surface again until the required thickness is achieved, and reinforcement of the existing structure is completed. According to the construction method for rapidly reinforcing the existing structure through the UHPC, vertical face and top construction is facilitated, the reinforcement efficiency and quality of a permanent structure and a temporary structure can be improved on the basis that an original structure is not damaged, and the construction period is shortened. And meanwhile, the period of reinforcement construction is shortened, and good economical efficiency and application prospects are achieved.
本发明公开了一种UHPC快速无损加固既有结构的方法，包括以下步骤：S1、预制轻质UHPC锚块；S2、对既有结构的待加固表面进行清理润湿，喷射高粘性UHPC，达到预定厚度后停止喷射，形成粘接层；S3、在粘结层初凝前向所述粘接层安装轻质UHPC锚块；S4、再次向待加固表面喷射早强UHPC，直至达到所需厚度，完成对既有结构的加固，本发明的UHPC快速无损加固既有结构施工方法便于立面和顶部施工，不破坏原有结构物的基础上可提升永久结构物、临时结构物的加固工效和质量，同时也缩短了加固施工的周期，具有较好的经济性及应用前景。
