Foundation pit supporting structure serving as corridor underpinning pile foundation and construction method of foundation pit supporting structure
The invention provides a foundation pit supporting structure serving as a corridor underpinning pile foundation and a construction method of the foundation pit supporting structure. The foundation pitsupporting structure comprises foundation pit fender piles, an underpinning bearing platform, underpinning pile foundations, a grouting reinforcement body, a concrete supporting structure, steel latticed columns, stand column piles and an existing corridor pile foundation, wherein the underpinning pile foundations are arranged at the two sides of the existing corridor pile foundation; the underpinning pile foundation at the side adjacent to the foundation pit is also used as a foundation pit fender pile, and the underpinning pile foundation at the side deviating from of the foundation pit isindependently arranged; and annular notches and radial embedded steel bars distributed in a quincunx shape are arranged on the outer surface of the corridor pile foundation, and additional longitudinal steel bars and additional annular steel bars are arranged at the outer side of the corridor pile foundation. The foundation pit supporting structure constructed through the method is convenient to construct and organize and low in construction cost, and meanwhile the safety control requirement of a corridor structure is met.
本发明提供一种兼作连廊托换桩基的基坑支护结构及其施工方法，该基坑支护结构包括基坑围护桩、托换承台、托换桩基、注浆加固体、砼支撑结构、钢格构柱、立柱桩和既有连廊桩基，其中托换桩基布置于既有连廊桩基的两侧，邻近基坑一侧的托换桩基由基坑围护桩兼作，背离基坑一侧的托换桩基独立设置。连廊桩基的外表面布置有环形槽口和梅花形分布的径向植筋，并在连廊桩基外侧设置了附加纵向钢筋和附加环形钢筋。本发明建设的基坑支护结构施工组织便捷，工程造价较低，同时满足连廊结构的安全控制要求。
