Abstract

The utility model discloses a sewer leakage-proof device, which comprises a round pipe (1), wherein a water receiving disc (2) is arranged on the periphery of the round pipe (1), and a reflux hole (1a) which can communicate the round pipe (1) and the water receiving disc (2) is opened on the round pipe (1) which is close to the bottom of the water receiving disc (2). The water receiving disc (2) and the round pipe (1) have the same shaft core, and are formed integrally, wherein the water receiving disc (2) is a round disc whose diameter is 1.5-2 times of the that of the round pipe (1). The utility model can collect water leaking from the cracks between a sewer pipe and concrete into the water receiving disc, and water can flow into the sewer pipe through the reflux hole. And the sewer leakage-proof device can be installed both undecorated houses and decorated houses to realize the purpose of leakage prevention. The sewer leakage-proof device has simpler structure, can be easily processed through one-time injection molding, and has lower cost.

Description

The sewer leak-proof device

Technical field

The utility model belongs to the device that is installed in sewer, specifically, is a kind of leak-proof device of sewer pipe.

Background technology

At present, in the building various pipes from flooring reserve or punch pass through after, in order to prevent that flooring poling place from leaking, generally be to do technical finesse usually from construction means and construction technology.Be after pipeline installs, take the concrete casting shutoff second time is carried out in the slit, hole the flooring concrete casting of poling place again.Because pipe is combining between two kinds of different materials with concrete, and tube outer wall smoother, bad adhesion between the two, especially plastic pipe is different with concrete temperature influence variation difference, pipe is through overexpansion-contraction-expansion-contraction, the slit appears in tube wall and concrete bonding place easily after a period of time, leaks thereby produce.In case and flooring produces the crack and leaks, and makes being difficult to effectively be solved again up.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of leak-proof device that prevents clearance leakage between sewer pipe and the concrete.

The technical solution of the utility model is as follows: a kind of sewer leak-proof device, comprise pipe, and its key is: described pipe excircle is provided with drip tray, has the return port that pipe is communicated with drip tray on the pipe near this drip tray bottom.Water channel leak-proof device pipe upper end is connected with the draining mouth of pipe of sewer.The water that seepage is got off between sewer gutter and the concrete crack has all flow in the leak-proof device drip tray.The backwater hole of water on drip tray that arrives drip tray flows back to pipe again discharges.The water that seepage is got off between sewer gutter and the concrete crack can not leak into down first floor always like this.When mounted, can directly be embedded in the concrete if newly spruce up.If the house of having fitted up, be installed in the below of flooring.

Above-mentioned drip tray of work in-process and pipe coaxial core, and be global formation, can open a mould, single injection-molded is processed more convenient.Above-mentioned drip tray is a circular discs, and diameter is 1.5～2 times of pipe.

Beneficial effect: the utility model can be collected in the water of seepage between sewer pipe and concrete crack in the drip tray, flows back to pipeline by backwater hole then.The house can be installed this sewer leak-proof device and reaches the purpose that prevents seepage before finishing and behind the finishing.This sewer leak-proof device is relatively simple for structure, and single injection-molded processing also is very easy to, and cost is also cheaper.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model first user mode figure;

Fig. 3 is the utility model second user mode figure;

Fig. 4 is the utility model the 3rd user mode figure.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, the utility model sewer leak-proof device, described pipe 1 excircle is provided with drip tray 2, is having the return port 1a that pipe 1 is communicated with drip tray 2 near on the pipe 1 of these drip tray 2 bottoms.Described drip tray 2 and pipe 1 coaxial core, the Pan Kou of drip tray and are global formation up.Described drip tray 2 is circular, and diameter is 1.5～2 times of pipe 1.

As shown in Figure 2, the house has been fitted up and has been finished, and the sewer leak-proof device is installed in the below of flooring 3, is contained between bedpan 4 sewer gutters and the bend pipe 5.These bedpan 4 sewer gutter mouths of pipe are inserted into the sewer leak-proof device pipe 1 upper end mouth of pipe.Following bend pipe 5 interfaces are inserted in the sewer leak-proof device pipe 1 lower end mouth of pipe.Sewer leak-proof device drip tray Pan Kou embeds in the cannelure that has below the flooring, and clings with glazing compound.

As shown in Figure 3, the sewer leak-proof device of installing during house decoration, sewer leak-proof device are installed in the concrete 6 between bedpan 4 and the flooring 3, and these bedpan 4 sewer gutter mouths of pipe are inserted into the sewer leak-proof device pipe 1 upper end mouth of pipe.Following bend pipe 5 interfaces are inserted in the sewer leak-proof device pipe 1 lower end mouth of pipe.

As shown in Figure 4, a sewer leak-proof device is installed in the concrete 6 of house decoration between bedpan 4 and flooring 3, the bedpan 4 sewer gutter mouths of pipe are inserted into the sewer leak-proof device pipe 1 upper end mouth of pipe.Following drain interface is inserted in the sewer leak-proof device pipe 1 lower end mouth of pipe.For another sewer leak-proof device is also installed in insurance more below flooring 3, this sewer leak-proof device upper end by gutter and a top sewer leak-proof device string together.This sewer leak-proof device lower end is connected with bend pipe 5.Reached duplicate protection.

Claims

1, a kind of sewer leak-proof device comprises pipe (1), it is characterized in that: described pipe (1) excircle is provided with drip tray (2), has the return port (1a) that pipe (1) is communicated with drip tray (2) on the pipe (1) near this drip tray (2) bottom.

2, according to the described sewer leak-proof device of claim 1, it is characterized in that: described drip tray (2) and pipe (1) coaxial core, and be global formation.

3, according to claim 1 or 2 described sewer leak-proof devices, it is characterized in that: described drip tray (2) is circular discs, and diameter is 1.5～2 times of pipe (1).
