Static pressure anchor rod pile combined pile with expanded underground space and construction method thereof
The invention relates to an underground expanded space static pressure anchor rod combined pile and a construction method thereof, and belongs to the technical field of rock-soil body engineering, and the underground expanded space static pressure anchor rod combined pile comprises a plurality of anchor rod piles implanted into a soil body in an array mode, inner core soil among the anchor rod piles and a concrete wall poured on the peripheral sides of the anchor rod piles. The concrete walls are poured on the outer peripheral sides of the anchor rod piles and the inner core soil, stable supporting force can be provided for the underground expansion space, the situation that an original building is shaken during underground space expansion construction is avoided, and the safety and stability of underground space expansion construction are improved on the premise that the construction efficiency and the construction progress are guaranteed.
本发明涉及一种地下拓展空间静压锚杆组合桩及其施工方法，属于岩土体工程技术领域，包括：多根呈阵列式植入土体内的锚杆桩、多根锚杆桩之间的内核心土及浇筑在多根锚杆桩外周侧的混凝土壁。本发明通过在多根锚杆桩及内核心土的外周侧浇筑混凝土壁，可以为地下拓展空间提供稳定的支撑力，避免地下空间拓展施工晃动原有建筑，在确保施工效率和施工进度的前提下，提高地下空间拓展施工的安全性和稳定性。
