[0020] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described.

[0021] Embodiment

[0022] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a deep basement floor anti-seepage structure, including a clay compaction layer 1, a waterproof layer 2, a filling layer 3 and a building concrete layer 4. The waterproof layer 2 is laid on the clay compaction layer 1, the filling layer 3 is filled and laid on the waterproof layer 2, and a buried blind ditch 5 for water collection is buried in the filling layer 3. The buried blind ditch 5 is arranged in a ∪-shaped structure with a large opening at the top. A drain pipe 51 for drainage is arranged inside the buried blind ditch 5. Gravel filter layers 52 are filled on both sides of the drain pipe 51 inside the buried blind ditch 5 through gravel. A wire mesh plate 53 for support is arranged at the top of the buried blind ditch 5. The building concrete layer 4 is laid on the filling layer 3 on both sides of the wire mesh plate 53; water permeable holes 511 are uniformly arranged on the outer circumferential wall of 2 / 3 of the upper part of the drain pipe 51; a geotextile 512 for preventing large particles from entering the inside of the drain pipe 51 is arranged between the water permeable holes 511 on both sides of the drain pipe 51 and the gravel filter layer 52; the gravel filter layers 52 on both sides above the drain pipe 51 are arranged in a thirty-degree inclined structure; the drain pipe 51 is connected to a sump; a building leveling layer is laid on the top of the building concrete layer 4, and drainage ditches are arranged on both sides of the building leveling layer. The drainage ditches are connected to the sump; the top of the wire mesh plate 53 is on the same horizontal plane as the building concrete layer 4.

[0023] It should be noted that this application reduces the risk of basement leakage, effectively guarantees the safety of basement personnel and equipment; enhances the waterproof ability of the basement, reduces the maintenance and repair costs caused by leakage; improves the use value and experience of the basement;

[0024] Furthermore, by arranging a drain pipe 51 inside the buried blind ditch 5, water permeable holes 511 are opened on the drain pipe 51, a gravel filter layer 52 is arranged outside the water permeable holes 511, and a geotextile 512 is arranged in the middle. The water collection ability is extremely strong, and the collected water can be quickly drained away, avoiding soil erosion. The bottom of the drain pipe 51 is a non-porous part, which is conducive to the rapid drainage of the collected water and prevents secondary leakage. At the same time, the outside of the drain pipe 51 is wrapped with a geotextile 512, which can not only ensure that groundwater penetrates through the gravel filter layer 52 and the geotextile 512 into the drain pipe, but also effectively prevent large particle objects from entering the drain pipe 51, preventing adverse factors caused by the blockage of the drain pipe 51 and ineffective diversion. By intercepting and filtering the sand and gravel in the flowing water through the gravel filter layer 52, the occurrence of basement leakage problems can be effectively prevented, the safety of the basement foundation can be guaranteed to the greatest extent, the normal use of the underground parking lot can be ensured, and the service life of the underground parking lot can be extended;

[0025] Furthermore, the filling layer 3 is a sand or gravel layer made of a material with a certain thickness. The filling layer 3 forms a protective layer and can also serve as a temporary storage space when water penetrates.

[0026] Furthermore, when the groundwater at the bottom of the soil compaction layer 1 enters the filling layer 3 through the gap between the waterproof layer 2 and the building wall, the drain pipe 51 inside the buried blind ditch 5 on one side of the filling layer 3 cooperates with the gravel filter layer 52 to collect water. The groundwater reaches the gravel filter layer 52 arranged in an inclined structure through the filling layer 3, enters the inside of the drain pipe 51 through the water permeable holes 511 and the geotextile 512 on the drain pipe 51, and the water collected inside the drain pipe 51 is quickly discharged to prevent secondary leakage. At the same time, the outside of the water permeable holes 511 of the drain pipe 51 is wrapped with the geotextile 512, which can not only ensure that the groundwater seeps into the drain pipe 51 through the geotextile 512, but also effectively prevent large particle objects from entering the drain pipe 51, thus avoiding the adverse factors caused by the blockage of the drain pipe 51 and the inability to effectively divert the flow.

[0027] Coarse-grained materials such as broken stones and gravel are filled outside the water permeable holes 511 on both sides of the drain pipe 51, so that a filter layer is arranged between the buried blind ditch 5 and the filling layer 3 for interception and filtration.

[0028] Furthermore, when there is water on the top surface of the building concrete layer 4, the water on the top surface moves down through the building concrete layer 4 to the filling layer 3. The bottom of the filling layer 3 is provided with a waterproof layer 2, and the water is intercepted at the top of the waterproof layer 2. Since there is a buried blind ditch 5 arranged below the filling layer 3, through the buried blind ditch 5 arranged in a ∪-shaped structure with a large top opening and cooperating with the gravel filter layer 52, a drain pipe 51 is arranged inside the buried blind ditch 5, water permeable holes 511 are opened on the drain pipe 51, a gravel filter layer 52 is arranged in the middle outside the water permeable holes 511, and a geotextile 512 is arranged. The water collected on the top of the waterproof layer 2 is collected through the drain pipe 51 and quickly discharged to the catch basin.

[0029] Furthermore, the top of the wire mesh plate 53 is on the same horizontal plane as the building concrete layer 4, and the top of the wire mesh plate 53 is lower than the building leveling layer on the top of the building concrete layer 4. On the one hand, it ensures the normal walking of pedestrians, and on the other hand, the water collected on the top of part of the building leveling layer can be diverted into the inside of the drain pipe 51 at the bottom of the wire mesh plate 53.

[0030] The working process of the utility model:

[0031] In use, a drain pipe 51 is arranged inside the buried blind ditch 5. Water permeable holes 511 are formed in the drain pipe 51. A gravel filter layer 52 is arranged outside the water permeable holes 511, and a geotextile 512 is arranged in the middle. The water collection capacity is extremely strong, and the collected water can be quickly drained away, avoiding soil erosion. The bottom of the drain pipe 51 is a non-porous part, which is conducive to the rapid discharge of the collected water and prevents secondary leakage. At the same time, the outside of the drain pipe 51 is wrapped with a geotextile 512. It can not only ensure that groundwater passes through the gravel filter layer 52 and penetrates through the geotextile 512 into the drain pipe, but also effectively prevent large particles from entering the drain pipe 51, preventing adverse factors caused by the blockage of the drain pipe 51 and ineffective diversion. By intercepting and filtering the sand and gravel in the flowing water through the gravel filter layer 52, the occurrence of basement leakage problems can be effectively prevented, ensuring the safety of the basement foundation to the greatest extent, and also ensuring the normal use of the underground parking lot and extending the service life of the underground parking lot;

[0032] When the groundwater at the bottom of the soil compaction layer 1 enters the filling layer 3 through the gap between the waterproof layer 2 and the building wall, the drain pipe 51 inside the buried blind ditch 5 on one side of the filling layer 3 cooperates with the gravel filter layer 52 to collect water. The groundwater reaches the gravel filter layer 52 arranged in an inclined structure through the filling layer 3, and enters the inside of the drain pipe 51 through the water permeable holes 511 and the geotextile 512 on the drain pipe 51. The water collected inside the drain pipe 51 is quickly discharged to prevent secondary leakage. At the same time, the outside of the water permeable holes 511 of the drain pipe 51 is wrapped with a geotextile 512. It can not only ensure that groundwater penetrates through the geotextile 512 into the drain pipe 51, but also effectively prevent large particles from entering the drain pipe 51, thereby preventing adverse factors caused by the blockage of the drain pipe 51 and ineffective diversion;

[0033] When there is water on the top surface of the building concrete layer 4, the top surface water moves down through the building concrete layer 4 to the filling layer 3. A waterproof layer 2 is arranged at the bottom of the filling layer 3, and the water is intercepted at the top of the waterproof layer 2. Since there is a buried blind ditch 5 arranged below the filling layer 3, through the buried blind ditch 5 arranged in a ∪-shaped structure with a large top opening and cooperating with the gravel filter layer 52, a drain pipe 51 is arranged inside the buried blind ditch 5. Water permeable holes 511 are formed in the drain pipe 51. A gravel filter layer 52 is arranged outside the water permeable holes 511, and a geotextile 512 is arranged in the middle. The water collected at the top of the waterproof layer 2 is collected through the drain pipe 51 and quickly discharged to the catch pit.
