Groove construction method based on assembly type section steel inner support
The invention provides a groove construction method based on an assembly type section steel inner support. The groove construction method comprises the following steps: surveying and setting out; manual exploration and excavation are conducted through a wang-shaped exploration and excavation method; performing trench excavation and supporting by matching a worker with an excavator; constructing a cushion layer; pipeline installation; backfilling layer by layer; and disassembling the finished supporting frame. A layered excavation and layered supporting mode is adopted for groove supporting, and after each soil layer is excavated, a plurality of finished product supporting frames are adopted for supporting and resisting soil pressure on the two sides of the formed groove; the finished supporting frame is made of profile steel, materials are easy to obtain, installation is convenient and fast, flexible adjustment can be carried out according to different excavation supporting lengths, depths and widths, universality is high, standard knot customizing and on-site splicing can be carried out on the whole by a manufacturer, construction is convenient, operation efficiency can be greatly improved, and construction time can be greatly shortened. When the structural steel inner support is used for groove construction, the safety of a foundation pit can be well guaranteed, the structural steel inner support can be matched with a steel plate to form a road, and traffic is recovered in the daytime on the basis that construction safety at night is guaranteed.
本发明提供一种基于装配式型钢内支撑的沟槽施工方法，包括：测量放线；“王字”探挖法人工探挖；人工配合挖机进行沟槽开挖与支护；垫层施工；管道安装；分层回填；成品支护架拆卸。沟槽支护采用分层开挖分层支护的方式，每一层土层开挖后均采用若干成品支护架支撑抵抗成型沟槽两侧土压力；成品支护架为型钢制成，材料易得、安装方便快捷，还可根据不同开挖支护长度、深度、宽度进行灵活调整，通用性强，整体可由厂家进行标准节定做，现场拼装，施工方便，能大大提高作业效率，缩短施工时间；利用本发明所设计的型钢内支撑进行沟槽施工时，能很好地保证基坑安全性，而且可配合钢板形成道路，在保证夜间施工安全基础上，白天恢复交通。
