The invention discloses an echelon pressurizing grouting anchor rod and a construction method thereof. The echelon pressurizing grouting anchor rod comprises a grouting anchor rod, wherein five layersof grouting holes are formed in the grouting anchor rod in the length direction of a rod body at equal intervals, the number of the layers of the grouting holes is one to five in sequence from the head to the tail of the grouting anchor rod, a first layer of rubber check rings are arranged on the inner wall of the grouting anchor rod in the direction from the position of the first layer of the grouting holes to the tail of the rod body of the grouting anchor rod at a half layer distance, four rubber check rings are arranged on the grouting anchor rod and are located on the rear part of the first layer of the rubber check rings in sequence, and the distance between every two adjacent rubber check rings is the same as that between every two adjacent grouting holes. The echelon pressurizinggrouting anchor rod has the advantages of simplicity, easiness and high efficiency in manufacturing, high utilization rate, high continuous cohesive force and high economy and applicability, the grouting area can be effectively enlarged, the grouting uniformity and compactness are enhanced, the grouting anchor rod can be tightly combined with surrounding soft soil, and the anchor rod can be prevented from falling off.
本发明公开了一种梯次加压注浆锚杆及其施工方法，包括注浆锚杆，所述注浆锚杆上沿杆体长度方向设置有五层等距的注浆孔，且由注浆锚杆头部向尾部依次为一~五层，所述第一层注浆孔位置向注浆锚杆杆体尾部方向距离半个层距处的注浆锚杆内壁布设有第一层橡胶止回圈，所述注浆锚杆上位于第一层橡胶止回圈的后部依次设置有四个橡胶止回圈，且每相邻两个橡胶止回圈之间的间距与每相邻两个注浆孔之间的间距相同。优点在于：装置简易，制作简单高效、利用率高，具有较高的持续粘结力，可有效扩大注浆面积，增强注浆均匀性和密实度，使注浆锚杆能够与周边软土紧密结合，可防止锚杆脱落，具有较高的经济性和适用性。
