Deep foundation pit supporting device and construction method
The deep foundation pit supporting device comprises an outer side cast-in-place pile, a middle cast-in-place pile and an inner side cast-in-place pile which are sequentially arranged from outside to inside, the height of the inner side cast-in-place pile and the height of the middle cast-in-place pile are the same and smaller than the height of the outer side cast-in-place pile, and the outer side cast-in-place pile is used for being arranged on the outer side of the outermost side wall of an underground structure. The inner side cast-in-place pile is used for being arranged on the outer side of the innermost side wall of an underground structure, an inclined strut is arranged between the top beam of the top of the outer side cast-in-place pile and the top beam of the top of the inner side cast-in-place pile, a connecting beam is arranged between the top beam of the inner side cast-in-place pile and the top beam of the top of the middle cast-in-place pile, and the connecting beam extends to the outer side cast-in-place pile and is fixed to the outer side cast-in-place The supporting device is good in stability, and the supporting requirement of a foundation pit with the excavation depth larger than 10 m is met.
本发明涉及一种深基坑支护装置及施工方法，包括由外向内依次设置的外侧灌注桩、中间灌注桩和内侧灌注桩，内侧灌注桩和中间灌注桩的高度相同且小于外侧灌注桩的高度，外侧灌注桩用于设置在地下结构最外侧墙体外侧，内侧灌注桩用于设置在地下结构最内侧墙体外侧，外侧灌注桩顶部冠梁和内侧灌注桩顶部冠梁之间设有斜撑，所述内侧灌注桩和中间灌注桩顶部冠梁之间设有连梁，连梁延伸至外侧灌注桩且与外侧灌注桩固定以形成三角形支撑结构，本发明的支护装置稳定性好，满足了开挖深度大于10米基坑的支护需求。
