Drainage channels 612 are formed in the water permeable layer 61, and the drainage channels 612 extend into the drainage grooves 7 so as to discharge water vapor permeating into the water permeable layer 61. The ventilation mechanism comprises an air inlet device 80 arranged outside the single villa, a main air duct 81 arranged in the patio 5 and communicated with the air inlet device 80, a first air inlet duct 83 communicated with the main air duct 81 in the patio 5 to introduce the outside air into the basement 200, and a first air outlet duct 84 used for discharging the air in the basement 200 into the patio 5; a fan for guiding the air is arranged on the main air duct 81 and/or the air outlet 50 of the courtyard 5, and an air duct opening 842 for exhausting the air flow from the first air outlet duct 84 to the courtyard 5 is arranged above the drainage groove 7, so that the air outlet of the first air outlet duct 84 is blown into the drainage groove 7.

Based on the design concept, as shown in fig. 2 and fig. 3, the basement moisture-proof ventilation system of the present embodiment mainly includes several parts, such as the patio 5, the ventilation mechanism, and the permeable layer 61 and the waterproof layer 62 in the ground.

Specifically, the ground of the present embodiment includes a foundation layer 60, a water permeable layer 61 below a waterproof layer 62, a water permeable layer 61 above the waterproof layer 62, a filling layer 63, and a finishing layer 64 sequentially laid from the foundation 1 upward. The basement 200 is provided with a base layer 60 on the ground to provide a stable foundation for the laying of the permeable layer 61 and the waterproof layer 62, and a filling layer 63 to facilitate the leveling of the ground to provide a good condition for the laying of the cover layer 64.

The foundation layer 60 may be a concrete layer, and may be formed by laying a layer of cement mortar after tamping the foundation of the foundation 1, and a reinforcement frame may be added to the foundation layer 60. When the base layer 60 is not hardened and formed, the permeable layer 61 below the waterproof layer 62 is laid to ensure that the permeable layer 61 and the base layer 60 are tightly attached. After waiting for the base layer 60 to be completely hardened, a waterproof layer 62 and a water permeable layer 61 above the waterproof layer 62 are laid. After the waterproof layer 62 is completely cured and formed, the filling layer 63 can be filled and the finish coat layer 64 is laid; the filling 63 is preferably provided with coarse sand mixed with a certain proportion of concrete. The portion in contact with the water permeable layer 61 needs to be increased in the amount of concrete to contribute to the strength of the filling layer 63 after molding. The top layer 64 is finished by paving floor tiles and the like.

The waterproof layer 62 is formed by laying an existing waterproof material. The main function of the permeable layer 61 is to form a drainage channel 612 for water vapor to flow through, for example, it can be laid by coarse aggregates such as ceramsite and pebble with a particle size of about 10mm, at this time, the gap in the ceramsite or the gap between the coarse aggregates form a drainage channel 612 for water to flow through, water permeating from the upper part of the ground enters the permeable layer 61 above after passing through the filling layer 63, water vapor permeating upwards from the base layer 60 enters the permeable layer 61 below, and water in the two permeable layers 61 can be drained into the drainage tank 7 through the drainage channel 612.

In this embodiment, the permeable layer 61 is in the form of splicing a plurality of permeable components. As shown in fig. 2, 3 and in conjunction with fig. 4. In this embodiment, the water permeable assembly includes a skeleton 611 and an inner lining member 610 disposed within the skeleton 611; the liner 610 is tubular and is used to shape the drainage channels 612 in the skeleton 611 to block the material of the filler layer 63 and the base layer 60 that has not been shaped from entering the drainage channels 612 formed in the skeleton 611 by the liner 610. The liner 610 can be peeled off from the skeleton 611, and when the liner 610 is peeled off, a drain channel 612 for collecting moisture from the filler layer 63 or the base layer 60 is formed in the skeleton 611. Permeable stratum 61 adopts the construction mode of the subassembly concatenation of permeating water, is convenient for provide the efficiency of construction, through the interior backing member 610 of the subassembly that permeates water, can peel off interior backing member 610 from the subassembly that permeates water after the construction on completion ground to form the drainage channel 612 that is used for discharging steam in permeable stratum 61, can fine realization permeable stratum 61's drainage dehumidification effect.

Specifically, the inner liner 610 includes an inner liner 6100 having an outer wall bonded to the frame 611, a sleeve embedded wire 6102 embedded in the wall of the inner liner 6100, and a pull wire 6101 disposed in the inner liner 6100. One end of the pull wire 6101 is located at one end of the inner sleeve 6100 and connected with the sleeve embedded wire 6102, and the other end of the pull wire 6101 is located outside the other end of the inner sleeve 6100. The inner lining 610 adopts the structure of the inner lining sleeve 6100, the sleeve embedded line 6102 and the pull wire 6101, so that the whole inner lining 610 is stripped from the water permeable assembly by pulling the pull wire 6101, which is beneficial to reducing the construction difficulty. The framework 611 can be formed by weaving iron wires or hard fiber nets, and includes a tubular water channel forming portion 6110 and connecting portions 6111 connected to two sides of the water channel forming portion 6110; the inner sleeve 6100 is bonded in the water passage forming portion 6110, and when the water permeable modules are spliced, the connecting portions 6111 of the two adjacent water permeable modules are abutted to complete the laying of the whole water permeable layer 61. The inner sleeve 6100 may be in the form of a flexible tube, such as a plastic tube; the pull wire 6101 and the sleeve-embedded wire 6102 may be nylon cords.

After the base layer 60 and the filling layer 63 in the ground have been hardened and set, the lining member 610 can be removed. It should be noted that, when laying the respective water permeable modules, preferably, the end of the pull wire 6101 connected with the casing embedded wire 6102 is arranged at the end far from the drainage groove 7; thus, the free end of the stay 6101 outside the inner sleeve 6100 is exposed to the drainage groove 7. When the liner 610 is stripped, by pulling the free end of the pull wire 6101, the pull wire 6101 pulls the sleeve embedded wire 6102 connected to the other end, and the sleeve embedded wire 6102 drives the liner sleeve 6100 to invert; as the pull wire 6101 is continuously pulled, the inner liner 6100 is continuously turned inward from the end away from the drain chute 7 toward the drain chute 7 to disengage from the backbone 611 until the entire inner liner 610 is peeled away.
