Temporary foundation pit pile-anchor supporting device and method for underneath passing existing road channel
The invention relates to a temporary foundation pit pile-anchor supporting structure and method for underneath passing an existing road passageway, an existing road is divided into a first half road needing excavation of a foundation pit and a second half road needing to keep passing of vehicles through a middle division zone, and the temporary foundation pit pile-anchor supporting structure comprises a plurality of supporting piles arranged along the middle division zone at intervals; the waist beam is connected with the pile bodies of the support piles in series; the pre-stressed anchor cables are arranged in the length direction of the waist beam at intervals, the first ends of the pre-stressed anchor cables are connected to the waist beam, and the second ends of the pre-stressed anchor cables are obliquely and downwards anchored into the lower portion of the second half-range road. The passage of the existing road is ensured by adopting a half-range construction form, and the passage of the existing road can be ensured while the underpass passage is constructed by matching with the foundation pit pile anchor temporary support.
本发明涉及一种下穿既有道路通道的临时基坑桩锚支护结构及支护方法，既有道路由中分带分成需开挖基坑的第一半幅道路以及需保持车辆通行的第二半幅道路，临时基坑桩锚支护结构包括：多根支护桩，沿所述中分带间隔设置；腰梁，串接多根所述支护桩的桩身；沿所述腰梁的长度方向间隔设置的多根预应力锚索，所述预应力锚索的第一端连接于所述腰梁，所述预应力锚索的第二端斜向下锚入所述第二半幅道路的下方。本发明采用半幅施工形式保证了既有道路的通行，配合基坑桩锚临时支护，可以在施工下穿通道的同时保证既有道路的通行。
