Pull-anchor combined type foundation pit supporting structure suitable for soft soil area and construction method of pull-anchor combined type foundation pit supporting structure
The invention discloses a pulling and anchoring combined type foundation pit supporting structure suitable for a soft soil area and a construction method of the pulling and anchoring combined type foundation pit supporting structure, and belongs to the technical field of foundation pit construction. The pulling and anchoring combined type foundation pit supporting structure comprises a row pile supporting component arranged on the excavation boundary of a foundation pit and a soil layer reinforcing body constructed in a deep and thick soft soil layer, and a pulling and anchoring fixing assembly is arranged between the row pile supporting component and the soil layer reinforcing body; the row pile supporting component is tensioned through the combination of the pulling anchor fixing assembly and the soil layer reinforcing body, and a stable foundation pit supporting structure is formed. According to the pulling and anchoring combined type foundation pit supporting structure suitable for the soft soil area, the structure is simple, the lengths of the free section and the anchoring section of the anchor rod can be effectively reduced, the overall stability of the foundation pit supporting structure is guaranteed, meanwhile, the application range of the pulling and anchoring supporting structure under the conditions of a deep and thick soft soil layer and the complex ground surrounding environment is widened, the engineering cost is reduced, and the economic benefit is increased. The construction difficulty is reduced, resources are saved, the strategic requirement of sustainable development is met, and good social and economic benefits are achieved.
本发明公开了一种适用于软土地区的拉锚组合式基坑支护结构及其施工方法，属于基坑施工技术领域，其包括设置于基坑开挖边界的排桩支护构件和施工于深厚软土层中的土层加固体，并在两者之间设置拉锚固定组件，以拉锚固定组件和土层加固体的组合形成对排桩支护构件的张拉，形成稳固的基坑支护结构。本发明的适用于软土地区的拉锚组合式基坑支护结构，其结构简单，能有效减少锚杆自由段和锚固段的长度，在保证基坑支护结构整体稳定性的同时，提高拉锚支护结构在深厚软土层且地面周边环境复杂情况下的适用范围，减小工程成本，降低了施工难度，节约资源，符合可持续发展的战略要求，具有很好的社会及经济效益。
