Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of toilet drainage, in particular to a toilet caisson secondary drainage structure. Background Art
[0002] A sunken bathroom refers to a bathroom structure that is partially or completely sunken from the corresponding floor to a certain height (usually 40cm) during the main construction, so that the bathroom's horizontal drainage pipe can be buried in it, and then backfilled with lightweight materials. The structural surface only needs to have one hole for the drainage riser. The drainage riser can be set in the corner of the wall, and the owner can use an external arc partition to cover it during decoration. At present, the drainage construction of the bathroom is to apply a waterproof layer on the bottom and wall of the bathroom, so that the bathroom constitutes an independent structure with a waterproof effect, and then fill the ground with sand and soil below the bathroom. After filling, the floor tiles are laid on the surface of the sand layer to complete the installation and laying of the bathroom floor.
[0003] Caisson-type toilets are very common in residential buildings. Because of the gravel layer in the middle of the caisson-type toilet, it will gradually sink over time. The cement layer and waterproof layer above will have cracks, and water will leak into the fill area. At the same time, when the water pipes buried in the fill layer burst and seep water, it will also cause water accumulation in the caisson. Because there is a waterproof layer below, the water cannot leak out, and as a result, it accumulates in the fill layer. Over time, the entire fill layer is filled with water; in order to prevent sewage from accumulating in the caisson, a small opening will be opened on the bottom side of the drainage pipe main for sewage discharge. However, there are two problems with this structure: First, there is no obstruction at the side opening of the drainage pipe main, and mud and sand are easy to block the drainage port during the backfilling of gravel and drainage. Once the drainage port on the side of the drainage pipe is blocked, sewage will accumulate in the caisson. Long-term water accumulation will make the wall damp and may also cause hidden dangers to the structure. Second, the drainage port is directly opened on the drainage pipe main, without any blocking equipment, and the gas cannot be isolated, and there is a smell in the bathroom. Utility Model Content

[0028] Reference Figure 1-5 A secondary drainage structure of a bathroom caisson in this embodiment includes a bathroom caisson 1, a drainage main pipe 2 is fixedly installed in the inner cavity of the bathroom caisson 1, and the outer surface of the drainage main pipe 2 is connected to a secondary drainer 3, the secondary drainer 3 includes a drainage box 31, a spring 32, a rotating rod 33, a baffle 34, a connecting plate 35, a first filter screen 36 and a second filter screen 37, and an infiltration water guide mechanism 4 is fixedly installed at the bottom of the inner cavity of the bathroom caisson 1, and the infiltration water guide mechanism 4 includes a concrete guide platform 41, a storage cavity 42, a filter plate 43, foam concrete 44, waterproof paint 45 and ceramic tiles 46.
[0029] like Figure 2 and 3 As shown, the top of the drainage box 31 is fixedly connected to the bottom of the No. 1 filter screen 36 , and the right side of the drainage box 31 is fixedly connected to the left side of the No. 2 filter screen 37 .
[0030] like Figure 2 and 3 As shown, the top of the inner cavity of the drainage box 31 is fixedly connected to the top of the connecting plate 35 , the left side of the connecting plate 35 is fixedly connected to one side of the spring 32 , and the other end of the spring 32 is fixedly connected to the right side of the baffle 34 .
[0031] like Figure 2 and 3 As shown, both ends of the rotating rod 33 are rotatably connected to the inner wall of the drainage box 31 , and the outer surface of the rotating rod 33 is fixedly connected to the inner surface of the baffle 34 .
[0032] like Figure 2 , 4 As shown in FIG. 5 , the top of the concrete guide platform 41 and the inner surface of the storage cavity 42 are fixedly connected to the outer surface of the waterproof paint 45 , the storage cavity 42 is opened on the concrete guide platform 41 , and the bottom of the filter plate 43 is fixedly connected to the top of the storage cavity 42 .
[0033] like Figure 2 , 4 As shown in FIG. 5 , the top of the waterproof paint 45 is fixedly connected to the bottom of the foamed concrete 44 , and the top of the foamed concrete 44 is fixedly connected to the bottom of the tile 46 .

[0035] In summary, when the toilet caisson 1 is constructed, the drainage box 31 is first fixed to the drainage main pipe 2 to connect the drainage main pipe 2 with the drainage box 31, and then the concrete guide platform 41 is filled into the toilet caisson 1, and a storage cavity 42 is reserved on the concrete guide platform 41 and the right side of the drainage box 31, and a slope toward the drainage box 31 is built on the concrete guide platform 41, and then waterproof paint 45 is applied to the concrete guide platform 41, the storage cavity 42 and the wall of the toilet caisson 1, and then the filter plate 43 is placed above the storage cavity 42 and the drainage box 31 to cover the storage cavity 42 and block the foam concrete 44 from the outside, and then the foam concrete 44 is spread on the toilet caisson 1. After the foam concrete 44 solidifies, tiles 46 are laid on top. When water seepage occurs in the bathroom caisson 1, the seeped water will penetrate to the bottom of the foam concrete 44, be blocked by the waterproof paint 45, and then follow the slope of the concrete guide platform 41, be introduced into the storage chamber 42, and will flow to the top of the drainage box 31, and then pass through the No. 1 filter 36 and the No. 2 filter 37 to enter the drainage box 31. When the thrust of the accumulated water is greater than the elastic force of the spring 32, it will push the baffle 34, and the baffle 34 will rotate in time to open the baffle 34, and the accumulated water will be discharged into the drainage main pipe 2. When the thrust of the accumulated water is less than the elastic force of the spring 32, the spring 32 drives the baffle 34 to rotate, so that the baffle 34 is closed again.
