SGP铁路桥梁预应力加固技术上海建泰预应力工程有限公司(简称SGP),是一家以预应力技术为特色,从事特种工程设计、施工、技术咨询的专业公司。在铁路桥梁加固工程领域,SGP应用创新的体外预应力加固技术,在完全不影响列车正常行车的情况下,采用体外预应力碳纤维带、体外预应力拉索等对桥梁进行加固,不仅大幅提高了桥梁的纵向刚度,减小了桥梁挠度,还可以释放桥梁受压区过大的压应力,使桥梁挠度校验系数和压应力校验系数恢复到规范常值范围。SGP体外预应力加固技术具有很好的技术经济性能,应用前景广阔。
SGP Railway Bridge prestressed reinforcement technology Shanghai Jian Tai Prestressed Engineering Co., Ltd. (hereinafter referred to as SGP), is a prestressed technology to engage in special engineering design, construction, technical advice of professional firms. In the field of railway bridge reinforcement engineering, SGP applies innovative external prestressing reinforcement technology to reinforce the bridge by externally prestressed carbon fiber ribbons and external prestressing cables, etc., not only greatly improving the normal operation of the train The longitudinal stiffness of the bridge reduces the deflection of the bridge and releases excessive compressive stress in the compression zone of the bridge to restore the bridge deflection calibration coefficient and the compressive stress calibration coefficient to the normal constant range. SGP external prestressed reinforcement technology has good technical and economic performance, broad application prospects.
