The invention relates to a pit supporting structure of underground engineering. The pit supporting structure comprises a pit, a horizontal plate-shaped support is arranged on the inner bottom surfaceof the pit in a super-ahead mode, a plurality of vertical supporting piles are arranged on the inner circumferential side of the pit, and the tops of the supporting piles are connected into an integral supporting structure through surrounding purlins. The pit supporting structure of the underground engineering is simple in structure and safe and stable in structure, the defects that a supporting pile of a traditional pit supporting structure is long, needs to penetrate through a soft soil layer, is large in deformation, long in construction period, multiple in procedure intersection and the like are overcome, moreover, a shaping tool type supporting structure is achieved, the construction speed is high, and repeated use can be achieved. The pit supporting device is suitable for supportingsmall-area pit excavation of basement pits, basement elevator shafts, tower crane foundations, pump rooms, septic tanks, underground pipelines and the like, and foundation pit supporting can be safely, economically, rapidly and effectively achieved.
本发明涉及一种地下工程的地坑支护结构，包括地坑，地坑内底面超前设置水平板状支撑，地坑内周侧排列设置有若干根竖直的支护桩，若干根支护桩顶部通过围檩联成整体的支承结构。该地下工程的地坑支护结构的构造简单，结构安全稳定，不仅克服了传统基坑支护结构的支护桩长度长，需穿透软土层，变形大、施工周期长、工序交叉多等不足，而且实现了定型工具式支护结构，施工速度快，可多次周转使用。适用于地下室坑中坑、地下室电梯井、塔吊基础、泵房、化粪池、地下管线等小面积地坑开挖的支护，更能实现安全、经济、快速、有效地基坑支护。
