The technical solution adopted in the present invention is: a kind of air-spacer comprises sealing bag, gasbag, sealing bag is located in gasbag, liquid raw material A is loaded in sealing bag, and solid raw material B is loaded in gasbag, and liquid raw material A, solid raw material B mixing produces gas.
Further, air-spacer also comprises fixed bar, fixed bar hollow, and fixed bar one end is located at that gasbag is outer, one end is located in gasbag, and fixed bar is communicated with sealing bag by rubber seal, the one end be located in gasbag establishing the one end outside gasbag.
All right, fixed bar hollow wall is provided with internal thread, and needle penetration surfaces screw thread is connected with hollow wall internal thread, and close gasbag outer end of threading a needle is provided with holddown groove.
Further, air-spacer also comprises pressure ram, and pressure ram one end is located at outside gasbag, the other end is located in gasbag, and the one end in gasbag is connected with sealing bag.
Further, air-spacer also comprises feed tube, and feed tube one end is communicated with gasbag, the other end is communicated with sealing bag, and liquid raw material A is housed in sealing bag, and solid raw material B is housed in gasbag.
Further, liquid raw material A is NaHCO
3or Ca (HCO3) 2 solution; Described solid raw material B is Al2 (SO4) 3 or CuSO4.
Further, liquid raw material A is water; Described solid raw material B is CaC
2.
Further, liquid raw material A is hydrochloric acid; Described solid raw material B is Zn.
The present invention is safe and reliable, simple to operate, easy to utilize, utilize gas that is fixing and liquid production, effectively can realize the shutoff to hole, the benefit of this device is, need not inflate in advance, liquid and solid reaction is allowed to produce gas after first this device can being put into hole again, easy and simple to handle and cost is lower.
