Instant pulling type prestress anchoring structure for supporting and anchoring method for supporting
The invention provides an instant pulling type prestress anchoring structure for supporting and an anchoring method for supporting. A prestress anchor rod is obliquely arranged, a bearing plate is arranged at one end of the prestress anchor rod, and the other end of the prestress anchor rod sequentially penetrates through a supporting pile, a steel pedestal and a steel waist beam and is locked on the steel waist beam through an anchorage device; a spiral blade is arranged on the outer side wall of the anchoring section and sleeves the pre-stressed anchor rod, one end of the anchoring section is clamped on the bearing plate, and the other end of the anchoring section is connected to one end of the connecting section; the prestressed anchor rod is sleeved with the connecting section, and the other end of the connecting section abuts against one side wall of the supporting pile. The steel pedestal is mounted on the other side wall of the support pile; and the steel waist beam is mounted on the steel pedestal. According to the device and method, grouting maintenance is avoided, the construction period is shortened, and the construction efficiency can be improved; the length of the pre-stressed anchor rod can be effectively shortened by adjusting the sizes of the spiral blades of the anchoring sections, the occupied area of foundation pit supporting is reduced, meanwhile, after a foundation pit is used, all used devices can be recycled, and the method is environmentally friendly.
本申请提供一种支护用即拉式预应力锚固结构及支护用锚固方法，其预应力锚杆倾斜设置，且一端上设有承压板，另一端依次穿过支护桩、钢台座以及钢腰梁，并通过锚具锁固于钢腰梁上；锚固节段的外侧壁上具有螺旋状叶片并套设于预应力锚杆上，且一端卡接于承压板上，另一端连接于连接节段的一端上；连接节段套设于预应力锚杆上，且另一端抵接于支护桩的一侧壁上；钢台座安装于支护桩的另一侧壁上；钢腰梁安装于钢台座上。该装置及方法无注浆养护，缩短了施工周期，可提高施工效率；其通过调节锚固节段的螺旋状叶片的大小可有效缩短预应力锚杆的长度，减少基坑支护占地范围，同时基坑使用完成后，所用器具均可回收再利用，绿色环保。
