Pressure self-balancing type capsule body and anchor rod with same

The utility model relates to the field of anchor rod construction, in particular to a pressure self-balancing type bag body and an anchor rod with the bag body, and the pressure self-balancing type bag body comprises the anchor rod, a steel pipe, the bag body and an exhaust hose. After the anchor rod is inserted into a soil body, grouting is conducted on the bag body, and the bag body achieves balance of internal pressure and external pressure of the bag body through the action of the scheduling hose, so that the bag body can be stably expanded till the bag body is completely opened, the bag body is filled with grout, and the grout in the bag body can play a bearing role after being solidified. The problems that the valve body is opened in advance due to insufficient pressure borne by the valve body in the bag body, slurry in the bag body is leaked, and then the bag body is difficult to fully open are solved. 本申请涉及锚杆施工领域，尤其是涉及一种压力自平衡式囊体及带有该囊体的锚杆，包括锚杆、钢管、囊体以及排气软管。通过将锚杆插入土体内后，对囊体进行灌浆，囊体通过排期软管的作用，实现囊体内外压力的平衡，从而使
