Bridge full-prefabricated substructure and construction method thereof
The invention relates to the technical field of bridge prefabrication and assembly, and discloses a bridge full-prefabricated lower structure which comprises a prefabricated pile and a combined bearing platform, the combined bearing platform comprises a prefabricated bearing platform body and a prefabricated pile cap, the prefabricated bearing platform body is provided with a prefabricated pile cap groove, and the prefabricated pile cap groove is used for placing the prefabricated pile cap; a grouting material is poured into a gap between the prefabricated pile cap groove and the prefabricated pile cap, an open groove is formed in the bottom of the prefabricated pile cap, a prefabricated pile open hole is formed in a bottom plate of the prefabricated bearing platform body and used for driving a prefabricated pile into the open groove, and the grouting material is poured into a gap between the prefabricated pile open hole and the prefabricated pile. The prefabricated pier is installed through the prestressed tendons, one ends of the prestressed tendons are anchored to the bottom of the prefabricated bearing platform body, the other ends of the prestressed tendons are anchored to the top of the pier, and the gap between the prefabricated pile cap and the prefabricated bearing platform covers the prefabricated pile driving deviation, so that the problem that the prefabricated bearing platform is not easy to install due to poor prefabricated pile driving precision is solved; and therefore, reliable and quick connection of the fully-prefabricated and assembled lower structure is realized.
本发明涉及桥梁预制拼装技术领域，公开了一种桥梁全预制下部结构，包括预制桩和组合承台，组合承台包括预制承台主体和预制桩帽，预制承台主体上设有预制桩帽槽，预制桩帽槽用于放入预制桩帽，预制桩帽槽与预制桩帽之间的缝隙中灌注灌浆料，预制桩帽的底部设有开槽，预制承台主体的底板设有预制桩开孔，预制桩开孔用于供预制桩打入至开槽，预制桩开孔与预制桩之间的缝隙中灌注灌浆料。本发明通过预应力筋安装预制桥墩，预应力筋一端锚固在预制承台主体的底部，另一端锚固在桥墩顶部，通过预制桩帽和预制承台间的空隙涵盖预制桩打入偏差，解决了由于预制桩打入精度差导致的预制承台不易安装的问题，进而实现了全预制拼装下部结构的可靠、快速连接。
