[0002] For the exterior walls of building basements, numerous metal sleeves are often installed to enter and exit the walls. Temporary sealing is required before the formal installation of pipes and wiring. Improper sealing can easily allow water to seep into the sleeves and into the building when the external soil water level rises, causing flooding and economic losses. Common sealing methods, such as mortar sealing or steel plate welding, are relatively cumbersome to install and difficult to remove later, and can also damage the pipes themselves. Therefore, a temporary sealing structure that is easy to install and dismantle is needed. Utility Model Content

[0005] Furthermore, the cover plate includes a plate body connected to the lead screw and rubber pads disposed around the lower perimeter of the plate body, wherein the size of the plate body corresponds to the size of the steel sleeve.

[0006] Furthermore, the rubber pad is arranged in a ring along the entire length of the main body of the plate, and the width of the rubber pad is not less than the thickness of the outlet pipe.

[0007] Furthermore, the support foot plate is threadedly connected to the lead screw and a first fastening nut is provided on the top surface. The support foot plate is a circular rigid plate.

[0008] Furthermore, the second fastening nut is tightly attached to the top surface of the main body of the plate, and the position of the second fastening nut is adapted to the main body of the plate being pressed and connected to the top of the outlet pipe.

[0009] Furthermore, the support arm is an elastic element, with two opposing support arms arranged in a figure-eight shape, and the vertical tilt angle is adapted to the support foot being pressed and connected to the side wall of the outlet pipe.

[0010] Furthermore, the support foot is a rectangular piece with a width and length greater than the width and length of the bottom end face of the support arm; the side of the support foot adjacent to the side wall of the outlet pipe is set as a rough surface.

[0011] The beneficial effects of this utility model are reflected in: This utility model, through the design of a cover plate, facilitates the sealing of the outlet pipe, and the second fastening nut ensures easy positioning and pressure sealing of the cover plate onto the outlet pipe. The support legs facilitate convenient temporary fixation of the support assembly to the inner wall of the outlet pipe.

[0014] Taking a circular steel inlet sleeve as an example, such as Figures 1 to 4As shown, the structure for temporarily blocking the outlet pipe includes an outlet pipe 1, a support component 3 temporarily connected to the outlet pipe 1, and a cover plate 2 disposed on the support component 3 and detachably connected to the top of the outlet pipe 1. In this embodiment, the cover plate 2 includes a plate body 21 connected to the lead screw and rubber pads 22 disposed around the lower perimeter of the plate body 21, wherein the dimensions of the plate body 21 correspond to the dimensions of the steel sleeve. The rubber pads 22 are arranged in a ring along the entire length of the plate body 21, and the width of the rubber pads 22 is not less than the thickness of the outlet pipe 1. The thickness of the plate body 21 is not less than 2 mm.

[0015] In this embodiment, the support assembly 3 includes a lead screw 31, a rod base 32 connected to the bottom of the lead screw, a support foot 33 detachably connected to the lead screw, and a first fastening nut 34 and a second fastening nut 35 connected to the lead screw; the first fastening nut 34 is located above the support foot 33 and below the cover plate 2, and the second fastening nut 35 is located above the cover plate 2.

[0016] In this embodiment, the support member 33 includes a support top plate 331 disposed on the lead screw, a support arm 332 connected to the lower periphery of the support top plate 331, and a support foot 333 disposed at the bottom of the support arm 332; the support arm 332 is arranged circumferentially on the support top plate 331, and each support foot 333 is connected to the side wall of the outlet pipe 1.

[0017] In this embodiment, the support plate 331 is threadedly connected to the lead screw 31 and a first fastening nut 34 is provided on its top surface. The support plate is a circular rigid plate. The second fastening nut 35 is tightly attached to the top surface of the plate body 21, and the position of the second fastening nut 35 is adapted to the plate body 21 to be pressed and connected to the top of the outlet pipe 1.

[0018] In this embodiment, the support arm 332 is an elastic element, and the two opposing support arms 332 are arranged in a figure-eight shape, with the vertical inclination angle adapted to the support foot 333 being pressed and connected to the side wall of the outlet pipe 1. The support foot 333 is a rectangular element, and its width and length are both greater than the width and length of the bottom end face of the support arm 332; the side of the support foot 333 adjacent to the side wall of the outlet pipe 1 is set as a rough surface.
