Existing expressway culvert in-situ demolition and newly-built structure and construction method thereof
The invention provides an existing highway culvert in-situ demolition and new construction structure and a construction method thereof, and belongs to the technical field of highway culvert construction.The existing highway culvert in-situ demolition and new construction structure comprises a jacking device arranged at an old culvert opening and used for circularly jacking a plurality of prefabricated culvert sections in alignment with an old culvert; the dismantling device is used for dismantling the old culvert step by step when the jacking device jacks the prefabricated culvert section; the supporting device is located in the old culvert and used for supporting the old culvert; and the slag ash cleaning device is used for cleaning the waste materials of the old culvert dismantled by the dismantling device and conveying the waste materials out of the old culvert. According to the method, the manufacturing cost of in-situ demolition and new construction of the culvert with the large soil covering depth can be effectively reduced, and the construction period and safety management and control are achieved.
本发明提供了一种既有高速公路涵洞原位拆除与新建结构及其施工方法，属于公路涵洞施工技术领域，包括顶进装置：设置在旧涵洞洞口，且用于将多个预制涵洞节段对准旧涵洞分别循环顶入；拆除装置：用于在顶进装置顶入预制涵洞节段时逐步拆除旧涵洞；支撑装置：位于旧涵洞内，且用于支撑旧涵洞；渣灰清理装置：用于清理拆除装置拆除的旧涵洞废料并运送至旧涵洞外。本发明能够有效降低原位拆除与新建覆土深度较深的涵洞的造价成本、实现工期以及安全的管控。
