Novel prestress bag type anchor rod system
The invention relates to a novel prestress bag type anchor rod system which comprises a prestress anchor rod and a grouting pipe. The pre-stressed anchor rod is sleeved with a sleeve, and the pre-stressed anchor rod is connected into the bag through a lock catch connecting device; the upper end of the cage core is connected to the bottom of the lock catch connecting device, and the lower end is fixed at the inner bottom of the bag; the grouting pipe extends into the bottom of the cage core, and the bag is filled with cement paste through grouting; cement paste is arranged outside the bag, and a bottom plate cushion layer is arranged at the top of the cement paste outside the bag; the pre-stressed anchor rod is sleeved with a spiral stirrup, a nut base plate is arranged at the top of the pre-stressed anchor rod, the nut base plate and the spiral stirrup are pressed on the bottom plate cushion layer by screwing an end nut into the upper end of the pre-stressed anchor rod, basement structure bottom plate pouring construction is carried out on the upper portion of the pre-stressed anchor rod, and a pre-stressed bag type anchor rod system is formed. According to the anti-floating anchor rod, the pulling resistance of the anti-floating anchor rod can be effectively improved, the anti-corrosion performance is good, the service life of parts is prolonged, and the engineering construction quality is improved.
本发明涉及一种新型预应力囊式锚杆系统，包括预应力锚杆和注浆管；预应力锚杆上套设有套管，且预应力锚杆通过锁扣连接装置接入到囊袋中；笼芯的上端连接到锁扣连接装置的底部，下端固定在囊袋的内底部；注浆管伸入到笼芯的底部，注浆使囊袋内充满水泥浆体；囊袋外设置有水泥浆体，并在囊袋外水泥浆体顶部设置底板垫层；预应力锚杆套设有螺旋箍筋，预应力锚杆顶部设置有螺母垫板，并通过端头螺母旋入预应力锚杆的上端将螺母垫板、螺旋箍筋压紧在底板垫层上，对预应力锚杆上方进行地下室结构底板浇筑施工，形成预应力囊式锚杆系统。本发明能有效提高抗浮锚杆的抗拔力，防腐性能好，既提高了零部件的使用寿命，又提高了工程施工的质量。
