The hydrophobic cavity 10 is filled with corrosion-resistant particles 18, preferably spherical ceramsite in this embodiment. The particles 18 are mutually abutted and crowded together, and a gap which can be passed by water flow and basically can not be circulated by cement can be formed, so that the drainage cavity 10 is filled with the ceramsite, and the problem that accumulated water can not be circulated due to the fact that the drainage cavity 10 is filled with the cement when cement is poured on the periphery side of the floor drain can be prevented.

With reference to fig. 3 and 4, the upper end of the rubber ring 7 extends into the gap between the water retaining ring 5 and the housing 9, and plays a certain role in blocking and sealing, so as to prevent silt from entering the drainage cavity 10 from the gap, and blocking the drainage cavity 10.

With reference to fig. 3 and 6, an annular step portion 12 is disposed at the edge of the lower nozzle 2, a plurality of water through holes two 13 are disposed on the wall surface of the step portion 12, and the water through holes two 13 communicate the lower nozzle 2 with the water through holes one 6. The inner side wall of the rubber ring 7 is matched with the step part 12 to form the floor drain installation position 3, the side surface of the floor drain core is attached to the inner side wall of the rubber ring 7, and the upper surface of the step part 12 is attached to the bottom of the floor drain core, so that the installation of the floor drain 20 on the floor drain installation position 3 is completed.

As shown in fig. 1, a circle of waterproof water guiding cloth 14 is further attached to the periphery of the water receiving platform 1, and in the present embodiment, polypropylene cloth is preferred. The water-diverting cloth 14 is arranged slightly inclined downward from the outside to the inside. Therefore, accumulated water can flow to the inner side from the outer side of the water accumulation cloth after the ground at a far place is infiltrated conveniently, and finally flows to the lower water port 2 to be discharged.

Further, with reference to fig. 3 and 6, a plurality of support ribs 17 are further disposed in the drainage cavity 10, and the upper sides of the support ribs 17 abut against the lower side of the housing 9, so as to support the housing 9 and prevent the housing 9 from collapsing downward due to the large pressure received by the outer side of the housing 9, which affects the use of the drainage cavity 10.

Meanwhile, as shown in fig. 6, a plurality of flow channels 16 which are inclined downward are further arranged on the circular table top of the water receiving platform 1, and the plurality of flow channels 16 respectively pass through the corresponding areas between the plurality of support rods. The outer end part of the support rib 17 in the drainage cavity 10 is provided with a plurality of auxiliary shielding plates 15. The auxiliary shielding plate 15 is right opposite to the flow guide hole 11 on the side part of the housing 9, a certain distance is arranged between the auxiliary shielding plate 15 and the flow guide hole on the side part of the housing 9, and the two sides of the auxiliary shielding plate 15 are also inclined towards the inner side of the whole device, so that accumulated water is guided to flow towards the area between the supporting rods on the two sides of the auxiliary shielding plate 15, and then is converged to the flow channel 16 to flow towards the lower water gap 2.

Finally, the seeped water under the ground is discharged through the structure, so that the seeped water is prevented from remaining on the cement bottom plate to cause the peculiar smell generated in a room and even damage to the cement bottom plate.

The specific working process of the scheme is as follows:

when the accumulated water enters the ground from the opening of the floor drain on the ground, the accumulated water flows to the pipeline from the drain opening 2 of the floor drain and is discharged as indicated by the arrow direction of the middle bent line in figure 3.

As shown in fig. 3, when the accumulated water permeates into the cement layer 19 from the ground around the floor drain, the flow direction of the water flow is as indicated by the arrow direction of the curved line at the side of fig. 3, the water flow is blocked by the water receiving platform 1 or the water guiding cloth 14, then the water flow naturally flows to the drainage cavity 10 through the flow guiding hole 11 due to the inclined arrangement of the water receiving platform 1 and the water guiding cloth 14, and then flows to the drain port 2 from the drainage cavity 10 through the water hole one 6 and the water through hole two 13 to be discharged.

A construction method of bathroom floor based on anti-seepage floor drain is applied to the anti-seepage structure of the launching device and mainly comprises the following steps:

as shown in fig. 7, S1, a water receiving platform 1 is installed at an upper port of a downcomer 25 of a floor 21; an auxiliary sleeve 26 is arranged in the middle of the water platform 1.

The inner and outer calibers of the auxiliary sleeve 26 are matched with the inner and outer calibers of the floor drain 20 to be installed, so that some states of the floor drain 20 installed on the water receiving platform 1 can be known in advance through the auxiliary sleeve 26, such as whether the lower end of the floor drain 20 can be inserted into the water receiving platform 1, whether the floor drain 20 is inclined and stable after being inserted, whether the floor drain 20 is matched with the water receiving platform 1, and the like. And then can handle some problems in advance, reduce floor drain 20 and install the possibility that the connection problem appears behind water receiving platform 1.

As shown in fig. 8, S2, paving a cement mortar layer 22 on the floor 21, wherein the cement mortar layer 22 covers the water receiving platform 1; the cement mortar layer 22 on the peripheral side of the horizontal table 1 is appropriately compacted.

Thereby closing the peripheral side of the water platform 1 by the cement mortar layer 22 and fixing the water platform 1 to the sewer pipe 25 of the floor 21. Meanwhile, the auxiliary sleeve 26 is further arranged in the middle of the water receiving platform 1, so that cement mortar can be blocked by the complex sleeve, and the cement mortar is prevented from entering the water outlet 2 in the middle of the water receiving platform 1. Meanwhile, the auxiliary sleeve 26 can also shape the cement mortar layer 22, so that enough installation space can be reserved after the cement mortar layer 22 is compacted and solidified, and the floor drain 20 is convenient to install.

As shown in fig. 9, S3, the auxiliary sleeve 26 is taken out, and the floor drain 20 is placed in the middle of the water platform 1.

After the inner and outer calibers of the auxiliary sleeve 26 are matched with the inner and outer calibers of the floor drain 20 and the sleeve is taken out, the cement mortar layer 22 can leave a groove matched with the floor drain 20, so that the floor drain 20 can be directly installed in the middle of the water receiving platform 1, and the operation is simpler and faster.

As shown in fig. 10, in S4, tiles 23 are laid on the cement mortar layer 22 on the periphery of the floor drain 20.

Thereby preventing a large amount of standing water on the ground from penetrating into the floor 21 by the tiles 23. Most of the accumulated water on the ground is finally drained out from the floor drain 20 to the sewer pipe 25 due to the shielding of the tiles 23, and a small amount of the accumulated water can permeate underground along gaps among the tiles 23, small crack gaps on the ground or gaps between the tiles 23 and the floor drain 20, and at the moment, the water receiving platform 1 in the anti-seepage structure can block the permeated accumulated water, and the accumulated water is guided to flow to the sewer port 2 through the drainage surface 4 to be collected and drained.

When the height of the lower water pipe 25 extending out of the base layer (i.e. the upper surface of the floor 21) is less than the expected height, an extension pipe can be installed on the port of the lower water pipe 25, and then the water receiving platform 1 is installed on the extension pipe, i.e. the height of the lower water pipe 25 is extended, so that the water receiving platform 1 can have enough installation space. Therefore, the water platform 1 can be arranged on the sewer pipes 25 with different extending heights through the extension pipes, and the water platform 1 can be adapted to more conditions and environments.

Further, in S2, the cement mortar layer 22 is formed by mixing sand and cement in a ratio of 3:1, adding a small amount of water, and mixing cement and sand to a viscous consistency which can be held to be a ball by hand.

According to the proportion and the viscosity reaching the degree, the sufficient plasticity during the pouring of the cement mortar layer 22 can be ensured, namely the viscosity and the sufficient hardness and strength after the cement mortar layer 22 is solidified can be ensured.

S3, before the auxiliary sleeve 26 is taken out, the auxiliary sleeve 26 is slightly shaken circumferentially; when the floor drain 20 is installed in the water receiving platform 1, cement paste needs to be smeared below the side part of the floor drain 20.

Thus, the auxiliary sleeve 26 slightly shakes in the circumferential direction, so that the floor drain 20 can have a space for applying cement paste when being arranged on the cement mortar layer 22. An installer firstly applies cement paste below the side part of the floor drain 20, then when the floor drain 20 is installed in the water receiving platform 1, the side part of the floor drain 20 abuts against the upper surface of the cement mortar layer 22, and the cement paste below the side part of the floor drain 20 can fill the gap between the floor drain 20 and the cement mortar layer 22, so that the sealing performance between the floor drain 20 and the cement mortar layer 22 is improved, accumulated water is further prevented from permeating underground from the gap between the floor drain 20 and the cement mortar layer 22, and the waterproofness of the anti-seepage mechanism is further improved.

In S4, when the tile 23 is laid, cement paste is applied to the lower surface of the tile 23.

The stability of the tile 23 when laid on the cement mortar layer 22 can be effectively improved through the viscosity of the cement mortar per se in the step. Meanwhile, gaps between the ceramic tiles 23 and the cement mortar layer 22 can be filled with cement paste, seeper is prevented from permeating to a certain extent, and certain waterproofness is improved.

Further, in the step S1, a seepage-proof film is laid on the floor 21 in advance, and the cement mortar layer 22 is laid on the seepage-proof film; the cement mortar layer 22 is leveled after the completion of the laying.

Thereby lay on floor 21 through prevention of seepage membrane, prevent that the ponding that is not caught by water receiving platform 1 from permeating floor 21 in and leading to floor 21 to damage, further strengthen the protection to floor 21, and then prevent that basic floor 21 from going wrong, and lead to the unable change of relevant structure of offal, influence the life-span of house even.

With reference to fig. 3 and 5, an upwardly extending step mounting portion 27 is formed at the upper end of the downcomer 25, and the water receiving platform 1 is sleeved on the step mounting portion 27, so that an installer only needs to align the downcomer 2 of the water receiving platform 1 with the step mounting portion 27 and then move the water receiving platform 1 downward, and the installation of the water receiving platform 1 on the downcomer 25 can be completed simply and quickly.

Meanwhile, with reference to fig. 3 and 6, a sealing ring 28 is further disposed between the water platform 1 and the step mounting portion 27. Therefore, the two sides of the sealing ring 28 are respectively abutted against the water receiving platform 1 and the step mounting part 27, the sealing of the gap between the two is realized, and cement mortar in the cement mortar layer 22 outside the water receiving platform 1 is prevented from entering the lower water opening 2 and the lower water pipe 25 of the water receiving platform 1 from the gap.

The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
