Fabricated grouting joint structure and construction method thereof
The invention designs a fabricated grouting node structure and a construction method thereof. The fabricated grouting node structure comprises an upper module, a pile foundation and a prefabricated pile core structure, and the upper module is connected with the pile foundation through the prefabricated pile core structure; the prefabricated pile core structure comprises a straight pile prefabricated pile core and an inclined pile prefabricated pile core, the inclined pile prefabricated pile core comprises steel corrugated pipes and a conversion steel disc, the two ends of the conversion steel disc are connected with the steel corrugated pipes, and the conversion steel disc is of an arc-shaped structure; the straight pile prefabricated pile core adopts a steel corrugated pipe as a template; the pile foundation comprises an inclined steel pipe pile and a straight steel pipe pile, the top of the inclined steel pipe pile is connected with the upper module through an inclined pile prefabricated pile core, and the straight steel pipe pile is connected with the upper module through a straight pile prefabricated pile core. The prefabricated pile core structure is placed between the upper module and the pile foundation and fixed through the grouting material, so that the upper module and the pile foundation are more stable, and meanwhile the problem of post-pouring plain concrete and the problem of cracks caused by shrinkage between new concrete and old concrete are solved.
本发明设计了一种装配式灌浆结点结构及其施工方法；其中，装配式灌浆结点结构包括上部模块、桩基以及预制桩芯结构，上部模块通过预制桩芯结构与桩基进行连接；预制桩芯结构包括直桩预制桩芯和斜桩预制桩芯，斜桩预制桩芯包括钢波纹管和转换钢盘，所述转换钢盘两端连接有钢波纹管，且转换钢盘为弧形结构；所述直桩预制桩芯采用钢波纹管作为模板；所述桩基包括斜钢管桩和直钢管桩，斜钢管桩顶部通过斜桩预制桩芯与上部模块连接，直钢管桩通过直桩预制桩芯与上部模块连接。本申请将预制桩芯结构放置在上部模块与桩基中间，并使用灌浆材料进行固定，使上部模块与桩基更加稳固，同时也解决了后浇素混凝土问题和新老混凝土间由于收缩出现裂缝的问题。
