Technical Field

[0001] The invention relates to an assembled anti-leakage drainage structure and a construction method thereof, belonging to the technical field of building decoration. Background Art

[0002] The building drainage system collects the water used by people in daily life and industrial production, and discharges it into the sewage pipe in time directly or after local treatment. According to the type of sewage accepted by the system, it is divided into three categories: domestic drainage system, industrial wastewater drainage system and rainwater drainage system.

[0003] Especially in water-related areas such as bathrooms, kitchens, and balconies, once leakage occurs due to poor drainage, it will not only cause inconvenience to the owners, but also have a significant impact on the quality and reputation of the entire decoration project. When poor drainage occurs, in addition to the possibility of leakage in the lower floor slab, it is very easy to cause the moisture in the cushion layer and bonding layer to penetrate along the floor to other rooms, and form water marks, mildew, blackening, etc. on the walls and floors of other rooms. To repair the leakage problem, only local surface plugging cannot achieve a thorough repair effect. The finishing layer must be chiseled off and waterproofed again, which may sometimes even damage the buried heating pipes, causing more serious leakage problems.

[0057]

[0058] During the construction of the traditional process, it is necessary to first construct the leveling mortar layer. The drain pipe part is plastered into a bowl shape to form a slope towards the drain pipe. Then, the waterproof additional layer enhancement treatment is carried out, and finally, the overall waterproof layer is constructed. The construction operation of this process is complex, and the requirements for detail treatment are relatively high. Once the treatment is not in place, it is extremely easy to cause local leakage.

[0059] In the present invention, by prefabricating a bowl-shaped anti-seepage part in the back field, it can be directly installed and fixed on-site, having the advantages of convenient construction, stable quality, and controllable cost. This drainage structural part can be combined with the mortar leveling layer to form an integral body, directly forming a slope towards the drain pipe and extending into the inner wall of the drain pipe by no less than 3 cm. When constructing the waterproof layer, it can be firmly attached to the surface of this structure to form a uniform and continuous waterproof layer structure that extends into the drain pipe, without the need for additional waterproof additional layer treatment. In addition, the upper opening of the drain pipe of the present invention is cut flush with the structural layer, and a circular groove is chiseled at the junction, and a waterproof sealing material is embedded to avoid potential leakage problems caused by the loose connection between the drain pipe and the structural layer. The present invention can save about 30% of the overall cost, save about 20 - 30% of the overall construction period, and reduce the leakage rate from 20 - 25% to zero leakage.

[0060] Adopting the above scheme, by setting an anti-seepage part in the mortar layer plane, and inserting the water guiding pipe part of the anti-seepage part smaller than the drain pipe into the drain pipe. After the waterproof layer is brushed on the surface of the mortar layer and the anti-seepage part, the waterproof layer can guide the sewage on the mortar layer to enter the water guiding pipe and the drain pipe in sequence, and the anti-seepage and drainage effect is excellent; and it does not need to use mortar to pour the funnel structure, and the installation is convenient and the quality is stable.

[0061] In addition, through the setting of the annular support plate, it can not only support the anti-seepage part, but also use the water permeable holes on the annular support plate to drain the water in the mortar layer into the drainage gap between the drain pipe and the water guiding pipe, so as to drain the seeping sewage.

[0062] In addition, by opening a waterproof groove at the junction of the drain pipe and the floor base layer and filling it with a waterproof sealing material, it can prevent sewage from seeping into the gap between the drain pipe and the floor base layer and damaging the connection structure.

[0063] The above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
