Cover-excavation top-down underground passage structure and construction method thereof
The invention discloses a cover-excavation top-down underground passage structure and a construction method thereof. The cover-excavation top-down underground passage structure comprises first supportpiles, hanging walls, a top plate, first side walls and a first bottom plate, the first support piles are arranged at intervals along the outer side lines of two sides of a passage, a top beam is arranged at the tops of each group of first support piles, the two hanging walls are arranged on the left side and the right side of the top plate correspondingly, the top plate is hung at a designed position through the two hanging walls, the upper ends of the hanging walls are fixedly connected with the top beams, the two first side walls are arranged at the bottoms of the two hanging walls correspondingly, the first bottom plate is arranged between the bottoms of the two first side walls, filling layers fill the portions between the first side walls and the first support piles on the corresponding sides and between the hanging walls and the first support piles on the corresponding sides, open excavation underground passage structures are constructed on the two sides of the cover-excavationtop-down underground passage structure correspondingly, the open excavation underground passage structures comprise second support piles, second side walls and second bottom plates. According to thecover-excavation top-down underground passage structure and the construction method thereof, the technical problems of narrow operation space, long construction period and high construction cost of traditional cover-excavation construction are solved.
一种盖挖逆作地下通道结构及其施工方法，包括第一支护桩、吊墙、顶板、第一侧墙和第一底板；第一支护桩沿着通道的两侧外边线间隔设置；每组第一支护桩顶部设有冠梁；吊墙有两块、分别设置在顶板的左右两侧，两块吊墙将顶板吊设在设计位置处；吊墙的上端与冠梁固定连接；第一侧墙有两块，对应设置在两块吊墙的底部；第一底板设在两块第一侧墙的底部之间；第一侧墙和吊墙与对应一侧的第一支护桩之间填充有填充层；在盖挖逆作地下通道结构两侧分别施工有明挖地下通道结构；明挖地下通道结构包括第二支护桩、第二侧墙和第二底板。本发明解决了传统的盖挖施工的作业空间狭小、施工工期长和施工成本高的技术问题。
