Underground chamber collapsible loess foundation reinforcing structure and construction method
The invention discloses an underground chamber collapsible loess foundation reinforcing structure and a construction method, the underground chamber collapsible loess foundation reinforcing structure comprises a chamber, a primary support and an advance support are constructed on the chamber, and feet of the primary support are provided with feet-lock bolts; the primary support is provided with grating steel frames, micro piles are arranged between the grating steel frames, and the micro piles penetrate through the collapsible loess layer and go deep into the non-collapsible loess layer. According to the method, the collapsible loess foundation is treated in the underground excavation chamber, the collapsibility of loess can be effectively reduced, and the safety risk in the use period is reduced. The underground chamber has the advantages that the structural integrity is high, the construction quality is easy to guarantee, and the influence on the surrounding environment is small, and the conditions for building the underground chamber in the self-weight collapsible loess area are effectively expanded.
本发明公开了一种地下硐室湿陷性黄土地基加固结构及施工方法，包括硐室，所述硐室上施做初期支护和超前支护，所述初期支护脚部打设锁脚锚杆；所述初期支护设有格栅钢架，所述格栅钢架之间布置微型桩，所述微型桩穿过湿陷性黄土层并深入非湿陷性黄土层。本发明实现了在暗挖硐室内对湿陷性黄土地基进行处理，能有效减少黄土的湿陷量，降低使用期的安全风险。具有结构整体性强、施工质量易保证、对周边环境影响小的优点，有效拓展了在自重湿陷性黄土地区修建地下硐室的条件。
