Annular self-locking anchoring support construction method for foundation pit
The invention discloses a foundation pit annular self-locking anchoring support construction method. The construction method comprises the steps of secant pile construction, first-layer earth excavation, ring beam construction, retard-bonded prestressed steel strand tensioning, second-layer earth excavation, ceramic hanging plate installation and the like. The mechanical properties of the retard-bonded prestressed steel strands and the ring beam made of the concrete are fully exerted, and the method has the advantages that the process is reliable, construction is simple, anchor cables and anchor rods do not need to be driven, damage to a center island soil body is small, the construction period is short, and stress is uniform.
本发明公开了基坑环形自锁锚固支护施工工法，包括咬合桩施工、第一层土方开挖、环梁施工、缓粘结预应力钢绞线张拉、第二层土方开挖以及陶瓷挂板安装等步骤。本发明充分发挥缓粘结预应力钢绞线以及混凝土制成的环梁的力学性能，具有工艺可靠，施工简洁，无需打锚索锚杆，对中心岛土体破坏小，施工周期短，受力均匀等优点。
