Tunnel section construction method
The invention relates to the field of civil engineering, and discloses a tunnel section construction method which comprises the processes of survey lofting, foundation pit segmented excavation, pump room supporting construction, pump room foundation pit excavation and the like, the processes of foundation pit segmented excavation and pump room foundation pit excavation both adopt a multi-layer excavation mode, and net hanging shotcrete anchor construction is conducted every time when one layer is excavated. And meanwhile, the structure of the temporary slope is dug out. The construction method has the beneficial effects that survey lofting, foundation pit segmented excavation, pump room supporting construction and pump room foundation pit excavation are adopted, construction of the tunnel section can be rapidly and effectively completed, the excavation task can be better completed through the segmented and layered excavation mode, a temporary slope is excavated in the excavation process, the stability can be improved, and the construction efficiency is improved. The net hanging and shotcreting mode can prevent the side slope from being subjected to weathering erosion and rainfall scouring from the outside to the inside, meanwhile, the pump house supporting construction and the pump house foundation pit excavation can guarantee that the construction of the pump house is completed, and the drainage effect in the tunnel is guaranteed.
本发明涉及土木工程领域，公开了一种隧道段施工方法，其包括测量放样、基坑分段开挖、泵房支护施工和泵房基坑开挖等过程，基坑分段开挖和泵房基坑开挖的过程均采用多层开挖的方式，并且每开挖一层均进行挂网喷锚施工，同时挖出临时边坡的结构。本发明的有益效果为：采用测量放样、基坑分段开挖，辅以泵房支护施工和泵房基坑开挖，能够快速有效的完成隧道段的施工，并且分段分层的开挖方式能够更好的完成挖掘任务，开挖过程中挖出临时边坡，可提高稳定性，挂网喷锚的方式可以防止边坡由表及里遭受风化侵蚀和降雨冲刷，同时泵房支护施工以及泵房基坑开挖可以保证泵房的施工完成，保证隧道内的排水效果。
