加固型地铁预应力梁体及制造方法
摘要：
本发明公开了一种加固型地铁预应力梁体及制造方法，其中，加固型地铁预应力梁体包括预应力混凝土梁和预应力孔道；所述预应力孔道的一端设置了一段长度的预应力孔道空洞和固体绝缘保护层；且所述预应力孔道空洞上设置了预留加固孔；通过预留加固孔对所述预应力孔道的一端的预应力孔道空洞内腔进行填充绝缘加固浆体可形成固体绝缘保护层。本发明提供的加固型地铁预应力梁体及制造方法，具有结构构造简易合理，制造方便、结构稳固可靠，耐久性强等多方面的技术优势。
摘要（英）：

The invention discloses a reinforcing type subway pre-stressed beam body and a manufacturing method. The reinforcing type subway pre-stressed beam body comprises a pre-stressed concrete beam and a pre-stressed duct; a pre-stressed duct cavity and a solid insulation protection layer with a certain length are arranged at one end of the pre-stressed duct; a reserved reinforcing hole is formed in thepre-stressed duct cavity; the pre-stressed duct hollow inner cavity in one end of the pre-stressed duct is filled with insulation reinforcing slurry through the reserved reinforcing hole, and thus thesolid insulation protection layer can be formed. The reinforcing type subway pre-stressed beam body and the manufacturing method have the technical advantages that the structure construction is simple and reasonable, manufacturing is convenient, the structure is stable and reliable, and the durability is high.
