[0006] In order to achieve the above objectives, the technical solution adopted by the utility model is:

[0007] A device for sealing a reserved pipe on the outer wall of a basement, comprising outer wall steel bars, a template and an embedded pipe, and also comprising a sealing plate, a plurality of screw rods and a plurality of fasteners, wherein the screw rods are arranged around the embedded pipe, the left end of the screw rods is fixed to the outer wall steel bars, the right end of the screw rods passes through the sealing plate, a plurality of fastening holes for the screw rods to pass through are arranged on the sealing plate, the sealing plate is arranged at the right end of the embedded pipe, the fasteners are threadedly connected to the screw rods, and the fasteners are fastened to make the sealing plate press-fit with the right end of the embedded pipe to seal the embedded pipe.

[0008] Furthermore, the right end of the screw rod extends from the exterior wall reinforcement along the embedded pipe, and the circumference of the screw rod is evenly distributed around the embedded pipe.

[0009] Furthermore, the screw rod is provided with an external thread, and the fastener is a nut, which cooperates with the external thread of the screw rod so that the sealing plate is press-fitted with the right end of the embedded pipe.

[0010] Furthermore, the blocking plate is a square steel plate.

[0011] Furthermore, the template is provided with an avoidance hole for avoiding the screw rod.

[0012] Furthermore, the diameter of the blocking plate is larger than the diameter of the reserved pipe opening.

[0013] Furthermore, the fastening holes are arranged on the edges of the blocking plate.

[0014] Beneficial effects of the utility model:

[0015] The utility model discloses a basement outer wall reserved pipe sealing device, which can effectively seal the basement outer wall embedded pipe by sealing the steel plate of the embedded pipe opening and the screw rod connecting the steel plate, so as to prevent outdoor backfill soil and rainwater from flowing into the basement through the embedded pipe, thereby forming an effective finished product protection for the basement.
