Description

TECHNICAL FIELD

[0001] The secondary drainage structure capable of preventing the water of the primary drainage from entering the backfill layer belongs to the technical field of bathroom drainage and specifically relates to the technical field of the secondary drainage structure capable of preventing the water of the primary drainage from entering the backfill layer. BACKGROUND

[0002] In the construction and decoration process of the current houses, the drainage of the bathroom includes the primary drainage and the secondary drainage. The primary drainage refers to the water flow to the floor drain for drainage by using the ground slope and the water ditch, and the secondary drainage refers to the water containing the accumulated water above the waterproof layer below the ground ceramic tile or stone material to be drained to drain the accumulated water in the backfill layer and avoid the leakage to affect the normal use of the house.

[0003] The existing secondary drainage mode generally buries a drainage pipeline at the bottom of the backfill layer, and the accumulated water in the backfill layer is drained through the top inlet of the drainage pipeline, but this secondary drainage mode makes the drainage pipeline only be buried at the bottom of the backfill layer and cannot pass through the backfill layer to the ground of the bathroom, so that the primary drainage and the secondary drainage need to be provided with a drainage pipeline respectively, the number of the pipelines is increased, the difficulty of pipeline arrangement is increased, and the drainage hole of the secondary drainage is arranged at the top of the drainage pipeline and is easily blocked by the concrete or impurities in the backfill layer, which affects the drainage effect.

[0004] In order to solve these problems, we applied for the secondary drainage structure patent with the application number 202121742268.4 to solve the above problems, but in the actual use process, we found that although one drainage pipeline can be shared for drainage operation, part of the water of the primary drainage will enter the backfill layer through the drainage opening, in order to prevent the above problems, we propose the secondary drainage structure capable of preventing the water of the primary drainage from entering the backfill layer. CONTENT OF THE INVENTION

[0005] The technical problem to be solved by the present application is to overcome the defects of the prior art and provide the secondary drainage structure capable of preventing the water of the primary drainage from entering the backfill layer, so as to solve the problem that the water of the primary drainage will enter the backfill layer through the drainage opening when the primary drainage and the secondary drainage share one drainage pipeline for drainage operation.

[0006] To achieve the above object, the present application provides the following technical scheme.

[0007] The secondary drainage structure capable of preventing primary drainage water from entering the backfill layer comprises a mounting pipe, drainage openings for water in the backfill layer to pass through are distributed on the mounting pipe, a filter screen is fixedly mounted outside the mounting pipe at the top end of the drainage openings, a blocking ring is arranged inside the mounting pipe at a position corresponding to the inner side of the top end of the drainage openings, and the bottom end of the blocking ring is arranged inside the sewage pipe of the bathroom drainage.

[0008] As a preferred technical scheme of the present application, the mounting pipe comprises a lower drainage pipe and an upper connecting pipe arranged in sequence from bottom to top, the lower drainage pipe is mounted at the top end of the sewage pipe of the bathroom drainage, the drainage openings are arranged at the joint position of the lower drainage pipe and the upper connecting pipe, and part of the drainage openings is arranged inside the sewage pipe of the bathroom drainage, and the other part of the drainage openings is arranged above the top end of the sewage pipe of the bathroom drainage.

[0009] As a preferred technical scheme of the present application, the filter screen can be arranged to fully cover the drainage openings above the top end of the sewage pipe of the bathroom drainage, and the bottom end of the blocking ring is between the bottom end of the drainage openings and the bottom end of the filter screen.

[0010] As a preferred technical scheme of the present application, a partition ring is mounted outside the upper connecting pipe, the filter screen is fixed at the bottom end of the partition ring, and positioning bosses are distributed at the bottom end of the partition ring outside the filter screen.

[0011] Compared with the prior art, the present application has the following beneficial effects: the blocking ring is arranged inside the mounting pipe at a position corresponding to the inner side of the top end of the drainage openings, and the bottom end of the blocking ring is arranged inside the sewage pipe of the bathroom drainage, so that the water of the primary drainage can directly enter the inside of the sewage pipe of the bathroom drainage, thereby effectively preventing the water from entering the backfill layer, and the filter screen is used to filter the secondary drainage, thereby preventing sundries from entering the sewage pipe of the bathroom drainage.
