The stubble blocking and separating air bag for casting high and low grade concrete comprises an air bag body 1, wherein the upper end of the air bag body 1 is connected with an inflating nozzle 2 as shown in figures 1-4. The charging nozzle 2 is a valve in the prior art, and when the valve is opened, gas enters the air bag body 1, and then the valve is automatically closed and sealed to store the gas. The air bag body 1 is cylindrical, a hard supporting part is arranged in the air bag body 1, the supporting part is flat, and the width of the supporting part is matched with the inner diameter of the air bag body 1 in the full-gas state. The length direction of the supporting part is consistent with the length direction of the air bag body 1, and the upper end and the lower end of the supporting part are respectively spaced 5mm-20mm from the inner side of the corresponding end of the air bag body 1; when the airbag body 1 is fully inflated, the left and right ends of the supporting part are propped against the airbag body 1. The supporting part is a rectangular frame 3, both the left end and the right end of the rectangular frame 3 are propped against the inner side of the air bag body 1, and the upper end and the lower end of the rectangular frame 3 are respectively spaced by 5mm-20mm from the inner side of the corresponding end of the air bag body 1. The middle part of the rectangular frame 3 is provided with a plurality of cross bars 4, and the left end and the right end of each cross bar 4 are respectively fixedly connected with the rectangular frame 3 at the corresponding end, so that the deformation resistance of the rectangular frame 3 is ensured, and meanwhile, the whole weight of the supporting part can be avoided. The rectangular frame 3 and the cross bar 4 are made of hard PVC plastic or other materials with better rigidity. The front side of the upper end part of the air bag body 1 is communicated with a deflation port 5, and the outlet end of the deflation port 5 is connected with a valve 6. The outlet end lock of the air release opening 5 is connected with a second protective cover 8, and concrete is prevented from entering the air release opening 5 through the second protective cover 8. The upper end fixedly connected with protection pipe 9 of gasbag body 1, charging connector 2 are located the protection pipe 9 inboard, and protection pipe 9 upper end detachably is connected with first protective cover 7. The first protection cover 7 covers the upper end of the protection circular tube 9, and the first protection cover 7 is in threaded connection with the protection circular tube 9. The outer side of the lower section of the protection circular tube 9 is integrally formed with an annular rib 10, and the annular rib 10 and the air bag body 1 are arranged at intervals. The protective circular tube 9 is sleeved with a sleeve ring 11, the sleeve ring 11 is positioned between the annular convex edge 10 and the air bag body 1, and the sleeve ring 11 can rotate around the protective circular tube 9. An elastic connecting piece 12 is fixedly connected between the lantern ring 11 and the first protective cover 7, and a pull ring 13 is fixedly connected to the middle part of the upper side of the first protective cover 7.
Working principle: in the initial state, the inside of the airbag body 1 is in a vacuum state, and the airbag body 1 is contracted into a flat shape attached to the support portion. When the air bag is used, the air bag body 1 is inserted between the adjacent beam steel bars and between the beam steel bars and the adjacent side templates, and the width direction of the adjusting support part is parallel to the length direction of the beam steel bars during insertion. The air bag body 1 is inflated through the inflation nozzle 2, after the air bag body 1 is inflated, the air bag body 1 is abutted against beam steel bars on two sides, so that the air bag body 1 and the beam steel bars are fixed together, and the adjacent air bags are abutted against each other, so that a circulation channel at the joint of high-grade concrete and low-grade concrete is blocked, and further waste caused by the fact that the high-grade concrete flows into a low-grade concrete pouring range is avoided.
