Abstract
Description
Technical Field
[0001] The utility model belongs to the field of domestic sewage and wastewater drainage in building interiors, and relates to a water-passing type drainage and waterproof combination part. Background Art
[0002] The building interior drainage system collects the water used by people in daily life and industrial production indoors respectively, and directly or after partial treatment, discharges it into the outdoor sewage pipeline in a timely manner. Some water will be collected into the drainage system through the ground slope. To prevent the ground water from penetrating into the next floor, a waterproof layer is usually made on the ground. The waterproof layer collects the ground drainage and discharges it into the indoor drainage pipeline. Here, it involves the drainage pipeline passing through the waterproof layer. At present, the method of the drainage pipeline passing through the waterproof layer in China is simple. Mainly, a sealing treatment is carried out at the place where the pipeline passes through the waterproof layer. Because the waterproof material and the pipeline are made of different materials, its sealing treatment highly depends on the plugging material and process. If there is a slight carelessness, this place will become a water leakage point. Content of the Utility Model
[0003] In order to solve the above technical problems existing in the prior art, the utility model provides a water-passing type drainage and waterproof combination part, and its specific technical solution is as follows:
[0004] A water-passing type drainage and waterproof combination part includes a pipe fitting main body located under the ground. An outer edge of the top of the pipe orifice of the pipe fitting main body is provided with a support connection ring, and a waterproof cloth is hermetically connected to the support connection ring. The waterproof cloth is lapped and matched with a waterproof layer made later in the ground; on an inner side wall of the pipe orifice of the pipe fitting main body, a plurality of protruding ribs are annularly arranged at intervals, and drainage grooves are formed between adjacent protruding ribs. A boss is provided at the bottom of each protruding rib, and they together form a support rib platform.
[0005] Further, the waterproof cloth is a flexible material, and its surface is a fibrous material.
[0006] Further, an upper surface of the waterproof cloth is lapped and matched with the waterproof layer made later in the ground.
[0007] Further, the drainage grooves communicate upward to the pipe orifice to access the wastewater flowing in from the waterproof cloth, and communicate downward to a lower drainage channel in the pipe fitting main body to discharge the wastewater.
[0008] Further, the bosses corresponding to the bottoms of the protruding ribs have equal heights.
[0009] Further, a limit support ring is further provided on an outer side wall of the pipe fitting main body, and the limit support ring is cast in a concrete floor slab under the ground.
[0010] Further, it further includes a drainage pipe inserted into the pipe fitting main body, and the support rib platform supports the drainage pipe.
[0011] Further, it also includes a decorative piece located on the ground and installed at the top pipe orifice of the drainage pipe.
[0012] Beneficial effects: By adding a transition piece when the pipe penetrates the waterproof layer in the present utility model, a sealed transition between the pipe and the waterproof layer is achieved, converting the waterproof problem of the pipe penetrating the waterproof layer into a problem of sealed connection between waterproof materials, and solving the problem of easy water leakage when the traditional pipe penetrates the waterproof layer.

Specific implementation manners
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0017] As Figure 1 and Figure 2 shown, a water-passing type drainage and waterproof combination part in this embodiment includes: a pipe body 1 located under the ground, a drainage pipe 2 inserted into the pipe body 1, and a decorative piece located on the ground and installed at the pipe orifice of the drainage pipe. An outer edge at the top of the pipe orifice of the pipe body 1 is provided with a support connection ring 3, and a waterproof cloth 4 is hermetically connected to the support connection ring 3. The support connection ring 3 and the waterproof cloth 4 are connected by a process and are very firm, achieving complete sealing. The upper surface of the waterproof cloth 4 is lapped and matched with the later-made waterproof layer 5 in the ground. The waterproof cloth 4 is a flexible material with a fibrous material on the surface. Therefore, the later-made waterproof layer 5 and the waterproof cloth 4 can be safely lapped, and based on the characteristics of the flexible material, this structural design is not afraid of the tiny gaps generated by the deformation between the pipe and the concrete.
[0018] A plurality of protruding ribs 6 are annularly arranged on the inner side wall of the pipe orifice of the pipe body 1 at intervals, and drainage grooves 7 are formed between adjacent protruding ribs 6. The drainage grooves 7 communicate upward to the pipe orifice to receive the waste water flowing in from the waterproof cloth 4, and communicate downward to the lower drainage channel in the pipe body 1 to discharge the waste water. Bottoms of the respective protruding ribs 6 are provided with bosses 8 having equal heights and together form a support rib platform, and the support rib platform supports the drainage pipe 2.
[0019] A limiting support ring 9 is provided on the outer side wall of the pipe fitting body 1. The limiting support ring 9 is cast in the concrete floor slab 10 below the ground, which can limit the up and down movement of the pipe fitting.
[0020] During use, the water on the floor tile 11 can flow into the drainage pipe 2 through the flower piece 12. The water between the floor tile 11 and the waterproof layer 5 made later can flow into the pipe through the rib grooves, namely drainage grooves 7, provided in the pipe fitting. Because there are protruding ribs 6 in the pipe fitting and there are gaps between the ribs, after the drainage pipe 2 is inserted, the water collected on the waterproof cloth 4 can flow into the drainage channel of the pipe, that is, the pipe fitting body 1, from the gaps at the bottom of the drainage grooves 7.
[0021] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If this specific posture changes, then the directional indication also changes accordingly. In the present invention, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
[0022] The above is only the preferred embodiment of the present invention and does not impose any form of limitation on the present invention. Although the implementation process of the present invention has been described in detail above, for those familiar with the art, they can still modify the technical solutions recorded in the foregoing examples or make equivalent replacements for some of the technical features. Any modifications, equivalent replacements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
