Combined type building seepage-proofing device for water pipes penetrating boards

Abstract

The invention relates to accessorial components for water drainage pipes, particularly to a combined type building seepage-proofing device for water pipes penetrating boards. The combined type building seepage-proofing device comprises a pre-buried pipe penetrating a floor, and a water bearing component; a bell mouth is formed at the upper end of the pre-buried pipe; the water bearing component comprises a water receiving plate and a dust cap; the water receiving plate adopts a ring-shaped structure; a pipe orifice at the lower part of the water receiving plate is matched with the bell mouth of the pre-buried pipe; a water receiving tank is arranged at the excircle of the water receiving plate; a water diversion slope surface is arranged on the outer edge of the water receiving tank; a drainage opening leading to the bell mouth of the pre-buried pipe is formed at the bottom of the water receiving tank; the dust cap is ring-shaped and is arranged over the water receiving tank in a covering manner; and a gap allowing water to flow through is left between the bottom of the dust cap and the water diversion slope surface of the water receiving tank. When the device is in use, ponding water at the upper part of the floor can flow into the water receiving tank along the water diversion slope surface and finally enters a water drainage pipe through the drainage opening, so that the problem that the water drainage pipe leaks water when penetrating the floor due to untightness in combination can be eliminated fundamentally.

Description

technical field [0001] The invention relates to an accessory component of a drainage pipe, in particular to a combined seepage preventer for a through-board water pipe used in buildings. Background technique [0002] In modern buildings, especially high-rise buildings, the design and installation of drainage pipes is a must. In the construction process, the wall is first built or the slabs between the layers are poured. Reserve a hole for installing the pipe at the position where the drain pipe passes, so that the drain pipe can be installed in the later stage of the building construction project. During the installation process, pour cement mortar between the contact pores between the pipe and the wall or floor to prevent leakage and seepage. However, due to the technical difficulty of secondary grouting to plug holes, the control of water-cement ratio is difficult, the workload is heavy, and the operation requirements are high. In actual construction, after the first hol...
