Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a bottom layer structure of a toilet is shown in figure 1 and comprises a water main 2 arranged inside a wall body 1, a pit 3 integrally formed with the wall body 1, a drain pipe 4 arranged inside the pit 3, a backfill layer 5 filled inside the pit 3 and a ground base layer 6 arranged above the backfill layer 5 and used for sealing the pit 3, wherein the backfill layer 5 is made of sand, concrete and the like, one end of the drain pipe 4 is connected to the water main 2, a part of the drain pipe 4 far away from the water main 2 is connected with a plurality of sewer pipes 7 upwards penetrating through the ground base layer 6, the sewer pipes 7 are respectively connected to drainage equipment (not shown in the figure), and the drainage equipment can be a wash platform, a washing machine, a closestool, a floor drain and the like. Be provided with a plurality of piers 12 between pit 3 bottom and ground basic unit 6 to play the effect of supporting ground basic unit 6, improve the steadiness of ground basic unit 6 structure, with the possibility that prevents that backfill layer 5 subsides and lead to ground basic unit 6 to sink.

As shown in fig. 1, in long-term rain weather, the inside of the backfill layer 5 is easy to be wet, and after a long time, the backfill layer is easy to be settled to affect the stability and durability, and the inside of the pit 3 is easy to get moldy and smelly, at this time, the moisture inside the backfill layer 5 can be slowly diffused through the breathing holes 10 which are formed in the upper surface of the ground base layer 6 and downwards penetrate through the ground base layer 6, so that the dryness inside the backfill layer 5 is kept as much as possible. And a rubber plug 11 for sealing the breathing hole 10 is further arranged on the ground substrate 6, so that an operator can plug the rubber plug 11 into the breathing hole 10 to prevent accumulated water on the upper surface of the ground substrate 6 from flowing into the backfill layer 5 from the breathing hole 10 to cause the possibility of moisture inside the backfill layer 5.

As figure 1, laid waterproofing membrane 13 in pit 3 bottom, waterproofing membrane 13 passes through the adhesive bonding in pit 3 bottom to when drain pipe 4 leaked in pit 3 is inside, sewage can permeate to pit 3 bottom through backfill layer 5, can effectively prevent it to continue to permeate downwards through waterproofing membrane 13 this moment, thereby has avoided lower floor's resident's wall body 1 to be soaked by ponding.

Referring to fig. 1 and 2, a dredging mechanism 8 for dredging the drain pipe 4 is provided at a portion of the ground substrate 6 between the water main 2 and the plurality of sewer pipes 7, the dredging mechanism 8 includes a square dredging opening 81 opened on the upper surface of the ground substrate 6 and downwardly penetrating the ground substrate 6, a square dredging groove 82 opened on the backfill layer 5 downwardly along the dredging opening 81, a ground substrate 83 provided on the groove wall and the groove bottom of the dredging groove 82, and a square cover plate 84 provided on the ground substrate 6 for closing the dredging opening 81, the drain pipe 4 penetrates the dredging groove 82, and a portion of the drain pipe 4 disposed in the dredging groove 82 is provided with a service pipe 85, both ends of the service pipe 85 are socket-connected to the drain pipe 4 by socket-fittings 86, which facilitates the service pipe 85 to be quickly detached from the drain pipe 4 by means of socket-connection, so that when the drain pipe 4 is clogged, the operator simply opens the cover plate 84 to expose the dredging channel 82 and then removes the service pipe 85 from the drain pipe 4, so that the drain pipe 4 can be dredged.

As shown in fig. 2, the thickness of the cover plate 84 is made to be consistent with the thickness of the ground substrate 6, a protrusion 841 is fixed on the upper portion of the cover plate 84 along the peripheral wall, and a slot 9 matched with the protrusion 841 is formed on the upper surface of the ground substrate 6 along the periphery of the dredging hole 81, so that when the cover plate 84 covers the dredging hole 81, the upper surface of the cover plate 84 can be flush with the upper surface of the ground substrate 6, and the bottom of the protrusion 841 is lapped on the bottom of the slot 9, thereby playing a role of supporting the cover plate 84 to prevent the cover plate 84 from falling into the dredging slot 82. In addition, the rubber sealing gaskets 842 arranged on the outer side wall and the bottom wall of the protrusion 841 play a role in sealing between the protrusion 841 and the slot 9 so as to prevent accumulated water on the upper surface of the ground substrate 6 from flowing into the dredging groove 82 from the gap between the protrusion 841 and the slot 9, thereby ensuring dry and clean inside the dredging groove 82.

As shown in fig. 2, a handle 843 is disposed on the upper surface of the cover plate 84, so that an operator can lift the cover plate 84, and meanwhile, a sinking groove 844 for the handle 843 to rotate into is disposed on the upper surface of the cover plate 84, and two ends of the handle 843 are rotatably connected to two side groove walls of the sinking groove 844, so that when the cover plate 84 closes the dredging hole 81, the operator can rotate the handle 843 into the sinking groove 844 to ensure the flatness of the upper surface of the cover plate 84, and the handle 843 is prevented from protruding out of the upper surface of the cover plate 84 and tripping over the operator.

As shown in fig. 1, a water outlet 821 is provided at one side of the bottom of the dredging groove 82, a water outlet pipe 822 having the other end connected to the water main 2 is connected to the water outlet 821, and a filter screen 823 for sealing the water outlet 821 is fixed at the bottom of the dredging groove 82, so that when the service pipe 85 is detached from the water discharge pipe 4 and the water discharge pipe 4 is dredged, the residue and the residual sewage in the water discharge pipe 4 flow into the dredging groove 82, and at this time, the sewage can flow into the water outlet pipe 822 through the water outlet 821 and then flow into the water main 2 through the water outlet pipe 822, so as to discharge the sewage in the dredging groove 82; in addition, the residues falling into the dredging groove 82 can be effectively intercepted by the filter screen 823, so that the residues are prevented from flowing into the water outlet pipe 822 along with sewage to block the water outlet pipe 822, and the residues can be taken out of the dredging groove 82 in a manual cleaning mode.

As shown in fig. 1, in order to facilitate the sewage inside the dredging groove 82 to be discharged quickly and completely to reduce the possibility of the sewage remaining at the bottom of the dredging groove 82, the bottom of the dredging groove 82 may be an inclined surface, and the water outlet 821 is provided at the lowest position of the bottom of the dredging groove 82.

The operation process is as follows: when the drain pipe 4 is blocked, the operator only needs to open the cover plate 84 to expose the dredging groove 82, and then the maintenance pipe 85 is detached from the drain pipe 4, so that the drain pipe 4 can be dredged.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
