Description

Technical Field

[0001] This utility model relates to the installation technology of water supply and drainage pipes passing through buildings, and in particular to a device for preventing water leakage and accumulation in the basement. Background Technology

[0002] During basement construction, the water supply and drainage pipes from the first floor need to be extended to the basement. To prevent water accumulation on the first floor from leaking into the basement through the pipe's penetration holes, anti-leakage measures are installed on the ground at these holes. However, the existing anti-leakage measures for the first-floor pipes are too low. When water accumulates on the first floor and the water level is higher than the top of the anti-leakage structure, water can easily leak from the top of the structure through the joint between the structure and the pipes into the basement. Furthermore, the existing anti-leakage measures lack protective devices and the pipes are not properly positioned and secured at the penetration holes. Utility Model Content

[0003] The purpose of this invention is to solve the problem of water leakage from the first floor to the basement through the through hole of the floor conduit. It provides a device that has good sealing performance, high leakage level, strong anti-leakage capability, convenient installation, can position and fix the floor conduit passing through the through hole, and protects the anti-leakage device from damage, thus preventing water leakage into the basement.

[0004] The purpose of this utility model can be achieved. This utility model's device for preventing water leakage into the basement includes a floor slab, a through hole, and a conduit. The device is characterized by: a lower positioning sleeve fixed below the floor slab and through hole using expansion bolts; an upper positioning sleeve fixed above the floor slab and through hole using expansion bolts; the lower and upper positioning sleeves constitute the positioning and fixing structure for the conduit; the conduit passing through the lower and upper positioning sleeves is positioned in the through hole; a large sealing gasket is provided between the lower part of the upper positioning sleeve and the floor slab; the large sealing gasket is pressed onto the floor slab by the upper positioning sleeve; the upper positioning sleeve, the floor slab, the through hole, and the large sealing gasket pressed between them constitute a primary leak-proof structure; the upper outer side of the upper positioning sleeve has external threads; the external threads of the upper positioning sleeve are connected to a protective cover through the internal threads of a protective cover; the protective cover constitutes the outer protective structure of the upper positioning sleeve.

[0005] This utility model relates to a device for preventing water leakage into basements. The upper positioning sleeve has a groove on its upper surface, forming an annular groove between the groove and the outer wall of the floor guide pipe. A small sealing gasket is placed on the bottom surface of the annular groove. An extension sleeve is provided on top of the upper positioning sleeve, with an annular boss at its bottom. External threads are provided on the outer vertical surface of the annular boss, and internal threads are provided on the vertical inner wall of the annular groove. The internal thread of the annular groove is threaded to the extension sleeve via the external thread of the annular boss. The threaded connection between the upper positioning sleeve and the extension sleeve, along with the small sealing gasket pressed between them, constitutes a two-stage leak-proof structure.

[0006] This utility model relates to a device for preventing water leakage into basements. The raised sleeve has a groove on its upper surface, forming an annular groove between the groove and the outer wall of the floor conduit. A small sealing gasket is placed on the bottom surface of the annular groove. A sealing sleeve is provided on the raised sleeve, with an annular sealing protrusion on its bottom surface. The annular sealing protrusion has an external thread on its vertical outer surface, and an internal thread on the vertical inner wall of the annular groove. The internal thread of the annular groove connects to the sealing sleeve via the external thread of the annular sealing protrusion. The raised sleeve, the sealing sleeve, and the small sealing gasket pressed between them constitute a three-stage leak-proof structure.

[0007] This utility model relates to a device for preventing water leakage into basements, wherein the lower positioning sleeve, upper positioning sleeve, protective cover, heightening sleeve, sealing sleeve, large sealing gasket, small sealing gasket, and floor-passing conduit are all coaxial.

[0008] This utility model relates to a device for preventing water leakage into the basement, wherein the inner diameters of the lower positioning sleeve, upper positioning sleeve, heightening sleeve, and sealing sleeve are dynamically matched with the outer diameter of the floor-passing conduit.

[0009] This utility model relates to a device for preventing water leakage into the basement, wherein the inner diameters of the large and small sealing gaskets are tightly fitted with the outer diameter of the floor conduit to form a sealing structure.

[0010] This utility model relates to a device for preventing water leakage into basements, wherein the lower or upper positioning sleeve is annular and the base is provided with several expansion bolt holes.

[0011] This utility model's device for preventing water leakage into basements differs from existing technologies in that it features a lower positioning sleeve fixed below the first-floor slab and the through-hole, and an upper positioning sleeve fixed above it. The lower and upper positioning sleeves together form the positioning and fixing structure for the floor-to-ceiling conduit. A large sealing gasket is provided between the upper positioning sleeve and the first-floor slab. The upper positioning sleeve, the first-floor slab, and the large sealing gasket pressed between them constitute a primary leak-proof structure. A protective cover is threaded onto the outer side of the upper positioning sleeve, forming a protective structure on the outside. A raised sleeve is threaded onto the upper positioning sleeve. The upper positioning sleeve, the raised sleeve, and the small sealing gasket pressed together by them constitute a secondary leak-proof structure. A sealing sleeve is threaded onto the raised sleeve. The raised sleeve, the sealing sleeve, and the small sealing gasket pressed together by them constitute a tertiary leak-proof structure. This utility model's device for preventing water leakage into basements has a reasonable structure and strong leak-proof capability, increasing the water level through the raised sleeve. It can position and fix the floor-to-ceiling conduit and protect the leak-proof device from damage.
