Supporting structure and box culvert integrated construction method for underneath passing existing bridge in limited space
The invention provides a supporting structure and box culvert integrated construction method for underneath passing of an existing bridge in a limited space. The method comprises the following steps that S1, construction preparation is conducted; s2, construction of cast-in-place piles; s3, high-pressure jet grouting pile construction; s4, breaking the pile head; s5, supporting structure construction; s6, earth excavation is conducted; s7, planting steel bars; the pile head of the third cast-in-place pile 7 is broken, and chiseling and bar planting treatment is conducted on the second cast-in-place pile 5; s8, box culvert formwork erecting pouring construction is completed; and S9, earthwork layered filling and rolling construction are conducted. On the premise that traffic operation safety of the existing road is guaranteed, the use requirement of a new project is met, meanwhile, the excavation earth volume of the foundation pit and the formwork project amount are reduced, the problems are solved, and the method has the advantages of being high in operability, reliability and safety.
本发明提供了一种有限空间内下穿既有桥梁的支护结构与箱涵一体化施工方法，包括以下步骤：S1、施工准备；S2、灌注桩施工；S3、高压旋喷桩施工；S4、破除桩头；S5、支护结构施工；S6、土方开挖；S7、植筋；破除第三灌注桩7桩头，进行第二灌注桩5桩凿毛、植筋处理；S8、完成箱涵立模浇筑施工；S9、土方分层填筑、碾压施工。本发明在保证既有公路交通运营安全前提下满足新建工程使用需要的同时，减少基坑开挖土方量和模板工程量，解决上述问题，具有可操作性强，可靠性高，安全性高的优点。
