Segmented construction method for large tunnel
The invention relates to a large tunnel segmented construction method which comprises the following steps: step S101, dividing a whole foundation pit into a preceding segment and a plurality of subsequent segments, and constructing a sealing partition wall at the adjacent positions of the preceding segment and the subsequent segments; s103, the first section is excavated, then a supporting assembly and a main body structure are sequentially constructed in the first section, and finally a force transmission belt is constructed between the main body structure and the sealing partition wall; s105, a plurality of follow-up sections are sequentially constructed until the whole foundation pit is constructed; the construction step of the subsequent section is the same as the construction step of the preceding section and the sealing partition wall in the step S101 and the construction step of the preceding section and the force transmission belt in the step S103. According to the construction method, the type of the sealing wall is the same as that of the foundation pit support structure, so that the sealing integrity of a plurality of separated small foundation pit support structures is guaranteed, and the construction quality of the small foundation pit support structures is improved; and according to different types of the sealing walls, the force transmission belts adopt different structures, matching is flexible, construction methods are diversified, and the construction effect is improved.
本发明涉及一种大隧道分段施工方法，包括以下步骤：步骤S101：将整个基坑划分为先行段和若干后续段，在先行段与后续段相邻处施工封隔墙；步骤S103：先对先行段进行开挖，再在先行段内依次施工支撑组件、主体结构，最后在主体结构与封隔墙之间施工传力带；步骤S105：对若干后续段依次进行施工，直至整个基坑施工完毕；后续段的施工步骤与步骤S101施工先行段及封隔墙、步骤S103施工先行段及传力带相同。本施工方法的封隔墙采用与基坑围护结构相同的类型，保证分隔成的若干小基坑围护结构封闭的完整性，提高小基坑的围护结构施工质量；且根据封隔墙的不同类型，传力带采用不同的结构，灵活配合，施工方法多样，提升施工效果。
