Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model.

The temporary sealing device for the reserved pipeline comprises a square steel plate 1, wherein a square rubber pad 2 is fixed on the square steel plate 1 through solid glue, the size of the square rubber pad 2 is slightly smaller than that of the square steel plate 1, but the side length of the square rubber pad 2 is larger than the diameter of the reserved pipeline 3, and in practical application, the size of the square rubber pad 2 can be designed larger, so that the temporary sealing device can be suitable for reserved pipelines 3 with more pipelines.

Four hollowed square 4 are uniformly arranged on the square rubber pad 2, a small U-shaped frame 5 is welded on a square steel plate 1 exposed out of the hollowed square 4, the opening of the small U-shaped frame 5 is downward, and a screw hole A6 is formed in the upper surface of the small U-shaped frame 5.
