Description

Secondary drainage structure of toilet

Technical Field

The application relates to the technical field of waterproof structures of caisson toilets, and particularly discloses a toilet secondary drainage structure.

Background

In house decoration, the floor and the wall of a toilet are generally paved with floor tiles, building materials or building garbage are used as fillers under the floor tiles, water on the surface of the floor tiles can easily permeate into the bottom of a filling layer through gaps of the floor tiles after the toilet is used for a long time, and the water permeating for a long time can fill the bottom space and even permeate into households below the floor from the floor tiles.

The present invention provides a secondary drainage structure for a toilet to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that water on the ground of the toilet permeates the backfill layer, so that the wall surface of the partition wall gets damp, becomes mildewed, returns alkali and the filling layer seeps water to permeate downstairs.

In order to achieve the purpose, the utility model provides a secondary drainage structure for a toilet, which comprises a caisson arranged in the toilet ground, a floor drain communicated with the toilet ground and the caisson, and a main drainage pipe penetrating through the caisson, wherein the side wall and the bottom of the caisson are both provided with waterproof layers, and the upper wall of the caisson comprises a floor brick layer, a mortar layer and a backfill layer which are sequentially arranged from top to bottom;

the floor drain comprises a water inlet and a water outlet, the water inlet is communicated with the ground of a toilet, the water outlet is arranged on the backfill layer, the water outlet is communicated with a secondary drain pipe, the free end of the secondary drain pipe is communicated with a main drain pipe, and the top of the backfill layer is provided with a plurality of grooves communicated with the floor drain.

The principle and effect of this basic scheme lie in:

1. the utility model provides a backfill layer top is equipped with the drainage concave groove of a plurality of not equidirectionals, and the water that permeates the mortar layer from ceramic tile layer gap continues to permeate the recess in, and water flows into the delivery port of floor drain from the recess, in the total drain pipe is gone into from the secondary drain pipe.

2. Compared with the prior art the utility model discloses be equipped with the recess between mortar layer and backfill layer, in the water that gets off from the mortar layer infiltration flows to the recess in concentrating, water collects the floor drain from the recess, in the secondary drain pipe row arrives total drain pipe again, can not continue to permeate the backfill layer but follow the secondary drain pipe and discharge from the water that the ceramic tile gap infiltration got off, the water infiltration that has solved bathroom ground leads to the wall to get damp and return alkali and the problem that backfill layer ponding permeates downstairs to the backfill layer.

Further, backfill layer bottom is equipped with the outlet, and backfill layer bottom surface is the slope, and the outlet is located the minimum, and the outlet rigid coupling has the drain pipe, and the free end and the total drain pipe intercommunication of drain pipe. The bottom of the backfill layer is provided with a water outlet to prevent water from flowing into the backfill layer to form accumulated water after the main water discharge pipe and the secondary water discharge pipe are aged.

Furthermore, the floor drain is a conical hidden floor drain, and a net cover is detachably connected to a water inlet of the conical hidden floor drain. The conical floor drain is beneficial to draining water, and the net cover prevents hairs or garbage from blocking the secondary drainage pipeline.

Further, a waterproof layer is arranged between the backfill layer and the mortar layer. The water of the waterproof layer further permeates into the backfill layer.

Furthermore, the backfill layer filler is foaming cement. The foamed cement has light weight and is heat-insulating.

Further, the recess is U type recess, and the both sides of recess are gone up the mouth edge and all are 45 degrees bevels, and the recess intussuseption is filled with the alum stone. 45-degree oblique angles of edges on two sides of the groove are favorable for water to flow into the groove, and the groove is filled with alumite to prevent mortar on a mortar layer from blocking the groove.

fig. 2 shows a top view of a U-shaped groove of a toilet drainage structure according to an embodiment of the present application.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the objects of the present invention, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.

Reference numerals in the drawings of the specification include: the device comprises a caisson wall 1, a mortar layer 2, a waterproof layer 3, a U-shaped groove 4, a conical hidden floor drain 5, a secondary drain pipe 6, a main drain pipe 7, a water outlet 8, a backfill layer 9 and alumite 10.

An example is shown in fig. 1 and 2. The caisson comprises a caisson, a main drainage pipe 7 penetrating through the caisson and a conical floor drain 5 embedded at the upper end of the caisson, waterproof layers 3 are laid on the side wall and the bottom of the caisson, a floor tile layer, a mortar layer 2 and a backfill layer 9 are sequentially arranged at the top of the caisson from top to bottom, the waterproof layers 3 are arranged between the mortar layer 2 and the backfill layer 9, the conical floor drain 5 comprises a water inlet and a water outlet, the water inlet is detachably connected with a net cover, the water inlet is flush with the floor tile layer, the water outlet is positioned on the backfill layer 9, the water outlet is fixedly connected with a secondary drainage pipe 6, the left end of the secondary drainage pipe 6 is communicated with the main drainage pipe 7, eight U-shaped grooves 4 are further formed in the top surface of the backfill layer 9 of the caisson, the eight U-shaped grooves 4 are symmetrically arranged, one ends of the U-shaped grooves 4 extend to the wall 1 of the caisson, the other ends of the U-shaped grooves 4 are gathered around the conical funnel and communicated with the conical funnel, the edges of the two sides of the U-shaped grooves 4 are inclined angles of 45 degrees, the U-shaped grooves 4 are filled with alumite 10, and the backfill layer 9 is filled with foaming cement;
