Soft soil layer foundation pit supporting device and supporting method thereof
The invention provides a soft soil layer foundation pit supporting device. The soft soil layer foundation pit supporting device comprises a spiral anchor rod, an extension rod and a grouting rod. The spiral anchor rod and the extension rod are further provided with retaining mechanisms. The spiral anchor rod comprises a spiral rod body, an advancing cone fixedly arranged at the front end of the spiral rod body and a spiral piece fixedly arranged on the outer side wall of the spiral rod body, the invention further provides a soft soil layer foundation pit supporting method using the supporting device, and the supporting device has the beneficial effects of being low in construction cost, small in construction amount, environmentally friendly, capable of being recycled and good in supporting effect; the anchor rod can be recycled and reused, the call for green and energy-saving building construction is responded, the tension of the anchor rod can be increased by using the soil stabilizer in combination with the spiral structure, and therefore the depth of the anchor rod is reduced.
本发明提供了一种软土层基坑支护装置包括：螺旋锚杆、延长杆以及注浆杆，所述螺旋锚杆与延长杆还设置有止退机构；所述螺旋锚杆包括螺旋杆体固定设置在螺旋杆体前端的前进锥、固定设置在螺旋杆体外侧壁的螺旋片，本发明还提供了利用上述支护装置的软土层基坑支护方法，具有施工成本低、施工量小、环保可回收和支护效果好的特点，锚杆可以回收重复使用，响应对绿色节能建筑施工的号召，土壤固化剂的使用结合螺旋结构可以增加锚杆的拉力，从而减少锚杆的深度。
