UHPC (Ultra High Performance Concrete) thin-shell system and method for reinforcing existing concrete structure by using UHPC thin-shell system
The invention discloses a UHPC thin shell system and a method for reinforcing an existing concrete structure, the UHPC thin shell system comprises a chamfered shell, a planar shell, a detachable steel plate, a bolt and UHPC which are installed on the periphery of the reinforced concrete structure, and the invention relates to the technical field of building structures. According to the UHPC thin-shell system and the method for reinforcing the existing concrete structure through the UHPC thin-shell system, the UHPC thin-shell system and the method for reinforcing the existing concrete structure through the UHPC thin-shell system are provided for carrying out external wrapping reinforcement on plateau high-altitude areas, coastal areas and other concrete structures with concrete structure freezing and thawing, salt and alkali corrosion and chemical corrosion. An isolation layer, a sealing layer and a protection layer are built between a reinforced body and an external erosion environment, the effect of the reinforcing system is reliable, UHPC with the thickness of 5-10 cm wraps and reinforces, the effect is higher than that of common concrete with the thickness of 30 cm, and permeation damage and freeze-thaw damage of external water and acid and alkali substances to a concrete structure can be prevented.
本发明公开了一种UHPC薄壳体系及其加固既有混凝土结构的方法，包括安装在被加固混凝土结构四周的倒角膜壳、平面膜壳、拆卸式钢板、螺栓、UHPC，本发明涉及建筑结构技术领域。该UHPC薄壳体系及其加固既有混凝土结构的方法，是针对高原高海拔地区、沿海地区以及其他存在混凝土结构冻融、盐碱、化学侵蚀的混凝土结构，进行外包裹加固所提出，该体系利用UHPC的抵抗冻融循环及化学侵蚀的优异性能，在被加固体与外部侵蚀环境之间建立起一个隔离层、封闭层、保护层，本加固系统效果可靠，5‑10cm的UHPC包裹加固，效果高于30cm的普通混凝土，可以防止外界水及酸碱物质对混凝土结构的渗透损害及冻融破坏。
