[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A construction method for anti-drainage and waterproofing of a concealed diversion trough bathroom comprises a base layer 2 cleaning process, a leveling layer 3 laying process, a waterproof layer coating process 4, a water-tightness test process, a waterproof protective layer 5 laying process, a concealed diversion trough 6 process and a surface layer paving process.

[0022] The cleaning process of the base layer 2 includes the steps of cleaning the surface of the base layer 2 and filling the uneven places with composite mortar. In the process of cleaning the surface of the base layer 2 and filling the uneven places with composite mortar, first clean the dust and debris on the base layer 2, then flatten and clean the mortar lumps and protruding parts remaining on the surface of the base layer 2, and smooth the corners into arcs or obtuse angles. The composite mortar is prepared by mixing 108 glue, cement and sand in a ratio of 1:1.5:2.5. After the composite mortar is added to the uneven places, use a scraper to scrape off the mortar that is higher than the base layer 2.

[0023] The process of laying the leveling layer 3 includes: A. applying the leveling layer 3 on the base layer 2; B. drying and curing the leveling layer 3. In step A of applying the leveling layer on the base layer 2, the leveling layer 3 slopes toward the floor drain 9 with a slope of 3%, and the intersection of the leveling layer 3 and the wall corner is smeared into a circular arc with a diameter of 30 mm, wherein the leveling layer 3 is a cement mortar layer, and the cement mortar is prepared by mixing cement, sand and water in a ratio of 1:3:0.6. In step B of drying and curing the leveling layer, the curing time is seven days, and the curing method is static curing.

[0024] The process of applying the waterproof layer 4 includes: A1. Applying waterproof coating around the pipe root, the floor drain 9, and the wall root; B1. Applying waterproof coating on the whole. In step A1 of applying waterproof coating on the pipe root, the floor drain 9, and the wall root, the redundant reserved pipe of the floor drain 9 is cut off at the root, so that the waterproof layer 4 can be circled inside the pipe. When the waterproof coating is not sticky, the whole waterproof coating is applied. In the whole waterproof coating B1, the coating is applied in four layers. After the waterproof coating is cured, the sewer pipe where the floor drain 9 is installed is blocked with cotton cloth to prevent foreign objects from falling into the pipe. The waterproof layer 4 completes the water-tightness test after 24 hours.

[0025] The closed water test process includes A2. Indoor water storage; B2. Leakage detection. Among them, in the indoor water storage step A2, the indoor water storage depth is 20 mm and the water storage time is one day; the leak detection step B2 includes the water storage surface drop inspection and the lower ceiling leakage inspection. During the implementation of steps A2 and B2, if there is no obvious drop in the water level and no leakage in the lower ceiling inspection, it is qualified. In the early stage of water storage, check downstairs once every 1 hour, and in the later stage, check downstairs once every 3 hours. If water leakage is found, drain the water immediately, improve the waterproof layer 4, and re-store water after the treatment is qualified.

[0026] The step of laying the waterproof protective layer 5 is to lay the waterproof protective layer 5 on the waterproof layer 4 .

[0027] The process of burying the guide trough includes the steps of preparing the opening of the guide trough 6 , installing the guide trough 6 , and temporarily fixing the guide trough 9 . In the preparation step for the opening of the guide groove 6, a square water inlet with a side length of ten millimeters is opened along the side of the guide groove 6, and the spacing between the square water inlets is thirty centimeters. A water guide hole with a diameter of three millimeters is opened along the top edge of the guide groove 6, and the spacing between the water guide holes is thirty centimeters. A U-shaped 20×40㎜PVC wire trough is selected as the guide groove 6, and the guide groove 6 is laid with the opening downward. The installation steps of the guide groove 6 include a. pre-placing the vertical guide groove 6 at the floor drain 9 and the waterproof sill 10 at the door; b. pre-placing the horizontal guide groove 6 at a position that does not cross the door sill 1. In steps a and b, the waterproof sill 10 is installed on both sides of the upper surface of the door sill 1. The guide groove 6 at the waterproof sill 10 is parallel to the waterproof sills 10 on both sides, and the horizontal intersection with the vertical guide groove 6 is unobstructed. The vertical guide groove 6 is connected to the floor drain 9 so as to remove the accumulated water in time. In the step of temporarily fixing the guide groove 9, the guide groove 6 is temporarily fixed to the waterproof protective layer 5 with transparent tape. On, in order to initially stabilize the placement position of the guide groove 9.

[0028] The surface paving process includes A3. laying the floor tile adhesive layer 7; B3. laying the floor tile 8. In step A3, the floor tile adhesive layer 7 is plain cement slurry, which is formed by mixing water and cement in a ratio of 0.42:1. The floor tile adhesive layer 7 slopes toward the floor drain 9 with a slope of 3%. During the implementation of step A3, step B3 is simultaneously implemented to ensure that the plain cement slurry does not dry and lose viscosity. When laying the floor tile 8, it is laid at a slope of 3% toward the floor drain 9. The floor drain position is cut in the middle of the floor tile, and the four sides are cut at 45 degrees. When installing the floor drain head, first plug the drain pipe mouth with an empty bottle, lay dry hard cement mortar around the drain pipe to test the floor drain head, and take out the floor drain head after completion, and use tools to clean the mortar at the edge of the opening on the guide groove 6 to ensure smooth drainage. After the floor tile 8 is laid, the floor drain head will be formally installed.

[0029] Horizontal and vertical guide grooves 6 are installed on the waterproof protective layer 5 of the bathroom, and are connected with the floor drain 9. Through the openings opened along the top and side of the guide groove 6, the accumulated water in the floor tile adhesive layer 7 can be gathered into the guide groove 6 and discharged into the floor drain 9 through the guide groove 6, which can effectively drain the accumulated water in the floor tile adhesive layer 7 of the bathroom. The guide groove 6 parallel to the door sill 1 is installed under the floor tile adhesive layer 7 on the inner side of the door sill 1 of the bathroom door, which can effectively prevent the accumulated water in the floor tile adhesive layer 7 of the bathroom from invading the adjacent room through the waterproof sill 10.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
