Problems solved by technology

However, this solution will cause the water in the drainage standpipe to flow back into the drainage device when the pipeline is undergoing water irrigation test, leaving a hidden danger of water coming out of the drainage device, and even cause the irrigation test to be suspended

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 with figure 2 As shown, the drainage standpipe platform includes a casing 3 sleeved on the drainage riser, a pipe fitting 7 for removing accumulated water, a water accumulation grate cover 5, and a waterproof wall 2 surrounding the sleeve pipe 3 and a waterproof wall 6 surrounding the pipe fitting 7.

[0019] The casing 3 and the exterior of the pipe 7 are connected together through a connecting piece 1 , and the waterproof walls 2 and 6 are substantially vertically arranged on the connecting piece 1 .

[0020] The above-mentioned accumulated water grate cover 5 communicates with the internal channel of the pipe fitting 7, and the accumulated water accumulated between the waterproof wall 2, waterproof wall 6, casing 3, and pipe fitting 7 can flow into the pipe fitting 7 through the through hole on the accumulated wate...

Abstract

The invention relates to a building water discharge vertical pipe table opening, which comprises a sleeve pipe and an accumulated water discharge pipe element, wherein the sleeve pipe can be sheathed on a water discharge vertical pipe, the sleeve pipe and the pipe element are connected into a whole through a connecting element arranged at the outer sides of the sleeve pipe and the pipe element, in addition, at least one waterproof wall which is basically vertical to the connecting element and surrounds the sleeve pipe and the pipe element is arranged around the outer sides of the sleeve pipe and the pipe element, and an accumulated water discharge hole is formed in the connecting element and is communicated with an internal passage of the pipe element. The internal passage of the sleeve pipe is not communicated with an internal passage of the accumulated water discharge pipe element, so all accumulated water in a pad layer of a water discharge system arranged at the same floor can be discharged out from the accumulated water discharge pipe element; during the water filling test of a water discharge vertical pipe, the water in the sleeve pipe cannot backwards flow out of the accumulated water discharge pipe element, so the water filling test of the water discharge vertical pipe can be normally carried out, and the backward flowing of gas in the water discharge vertical pipe cannot be caused.

Description

technical field [0001] The invention relates to a building drainage component, in particular to a platform opening of a building drainage standpipe on a floor. Background technique [0002] In the current bathroom drainage system on the same floor, the connection between the drainage standpipe and the horizontal branch pipe is above the floor. Therefore, for the sake of aesthetics, the connection nozzle position of the drainage riser pipe and the horizontal branch pipe must be below the ground decoration layer. When there is water seepage in the ground decoration layer, water may accumulate under the ground decoration layer, and even leak to the lower layer at the weak link at the position of the standpipe, or escape under the ground decoration layer to the bottom of the decoration layer in other rooms. [0003] At present, in response to this problem, there is a plan to set up a drainage device to drain the accumulated water under the ground decoration layer into the draina...
