Pile-anchor combined supporting structure for building foundation pit
The invention provides a pile-anchor combined supporting structure for a building foundation pit. The pile-anchor combined supporting structure comprises a plurality of anchor rod assemblies and supporting piles arranged along the inner wall of the periphery of the foundation pit, the anchor rod assemblies randomly penetrate through the supporting piles and then are inserted into a foundation pitsoil body, each anchor rod assembly comprises a steel strand and a hollow anchor pipe, and the inner end, extending into the foundation pit soil body, of each anchor pipe is provided with a bearing head. Anchor heads are arranged at the outer ends, exposed out of the outer surfaces of the supporting piles, of the anchor pipes, the steel strands are contained in the anchor pipes and circuitously wound between the bearing heads and the anchor heads by at least one circle, and gaps between the anchor pipes and the steel strands are filled with cement mortar. By the adoption of the technical scheme, the soil body on the inner wall of the foundation pit is protected through the supporting piles, the anchor rod assemblies are inserted into the supporting piles, reinforcing ribs are inserted intothe supporting piles, thus the foundation pit soil body and the supporting piles are connected into a whole, the supporting effect is enhanced, and safety is improved; and after foundation pit engineering is constructed, the reinforcing ribs and the steel strands can be taken out by chiseling away concrete, and steel resources can be saved advantageously.
本发明提供一种建筑基坑桩锚联合支护结构，包括多根锚杆组件和沿着基坑四周内壁布置的支护桩，锚杆组件随机的贯穿支护桩之后插入基坑土体以内，锚杆组件包括钢绞线和中空状锚管，锚管伸入基坑土体以内的里端安装有承接头，锚管暴露于支护桩外表面的外端设置为锚头，钢绞线容纳于锚管内并且迂回缠绕在承接头与锚头之间至少一圈，锚管与钢绞线之间的空隙内填充有水泥砂浆。采用本发明的技术方案，通过支护桩对基坑内壁土体进行防护，通过向支护桩内插入锚杆组件，在支护桩内插入加强筋，使基坑土体与支护桩连接为一体，增强了支护效果，提升了安全性，当基坑工程施工结束后，通过凿除混凝土可取出加强筋和钢绞线，有利于节省钢铁资源。
