During specific implementation, the preset length and the preset value-added can be determined according to actual conditions, and the present embodiment does not impose any restrictions on this. In the present embodiment, the preset length is 50 cm, and the preset value-added is 10 cm, then the plane size of the cushion layer 1 is 50 cm × (the width of the through-wall pipe + 10 cm). Among them, the width of the through-wall pipe is the overall width of all through-wall pipes.
[0020] The material of the cushion layer 1 can be determined according to actual conditions, and this embodiment does not impose any limitation on this. Preferably, the cushion layer 1 is made of concrete, and specifically, the cushion layer 1 is made of C15 concrete.
[0021] The cushion layer 1 is in contact with the side wall of the basement 5. Specifically, the cushion layer 1 is perpendicular to the side wall of the basement 5, and the backfill soil below the cushion layer 1 is compacted layer by layer.
[0022] The permeable retaining layer 2 is in a rectangular parallelepiped shape, and the permeable retaining layer 2 is in a closed state, and the inside of the permeable retaining layer 2 is hollow. The bottom of the permeable retaining layer 2 is placed on the cushion layer 1, one side of the permeable retaining layer 2 is in contact with the side wall of the basement 5, the outside of the permeable retaining layer 2 is in contact with the backfill soil, and the inside of the permeable retaining layer 2 is filled with a permeable filler 3. Specifically, the permeable retaining layer 2 is a reverse filter geotextile, and the permeable filler 3 is graded crushed stone. The permeable retaining layer 2 has the functions of water permeability and soil retaining.
[0023] During specific implementation, the anti-filter geotextile is laid along six directions of the rectangular parallelepiped, one side of the anti-filter geotextile is placed on the cushion layer 1, and the inside of the anti-filter geotextile is filled with the permeable filler 3. The filling of the permeable filler 3 and the backfill soil outside the anti-filter geotextile are constructed simultaneously. The anti-filter geotextile separates the permeable filler 3 from the backfill soil, and the anti-filter geotextile is an isolation layer between the permeable filler 3 and the backfill soil.
[0024] The first end of the through-wall pipe 7 ( Figure 1 The left end of the through-wall pipe 7 is placed in the basement 5, and the through-wall pipe 7 is passed through the two opposite side walls of the permeable retaining layer 2 and the permeable filler 3. The second end of the through-wall pipe 7 ( Figure 1 The right end of the through-wall pipe 7 is used to be placed in the well chamber 6. Specifically, the first end of the through-wall pipe 7 is placed inside the basement 5, and the through-wall pipe 7 is sequentially passed through the side wall of the basement 5, the side wall of the permeable retaining layer 2 in contact with the side wall of the basement 5, the permeable filler 3, the side wall of the permeable retaining layer 2 opposite to the side wall of the basement 5, and the side wall of the well chamber 6, and the second end of the through-wall pipe 7 is placed inside the well chamber 6.
[0025] Preferably, the through-wall pipe 7 is placed in the middle of the permeable retaining layer 2, and the top of the through-wall pipe 7 and the permeable retaining layer 2 are placed at the top ( Figure 1 The second preset distance is between the wall-penetrating pipe 7 at the bottom and the bottom of the permeable retaining layer 2 ( Figure 1 In specific implementation, the second preset distance and the third preset distance can be determined according to actual conditions, and this embodiment does not impose any restrictions on this. In this embodiment, the second preset distance is 20 cm.
[0026] The first end of the drain pipe 4 ( Figure 1The left end of the drain pipe 4 is placed inside the permeable retaining layer 2, and the first end of the drain pipe 4 is in contact with the bottom of the permeable retaining layer 2. The drain pipe 4 is arranged on the side wall of the permeable retaining layer 2 opposite to the basement 5, and the second end of the drain pipe 4 is used to communicate with the rainwater well. Specifically, the pipe section of the drain pipe 4 placed inside the permeable retaining layer 2 is in contact with the bottom wall inside the permeable retaining layer 2. The drain pipe 4 only needs to be placed inside the permeable retaining layer 2, and the permeable filler 3 compacts and fixes the drain pipe 4. The drain pipe 4 is used to discharge the groundwater in the permeable retaining layer 2 into the rainwater well.
[0027] Preferably, the drain pipe 4 is in an inclined state, and the drain pipe 4 gradually inclines downward from the first end to the second end. In this way, groundwater in the permeable retaining layer 2 can be discharged to the rainwater well through the drain pipe 4. More preferably, the inclination of the drain pipe 4 is greater than or equal to 0.3%.
[0028] Preferably, the drain pipe 4 is a PVC drain pipe.

Moreover, the groundwater seeps through the permeable filling material 3 to the bottom of the permeable retaining layer 2, and is then transported to the rainwater well through the drainage pipe 4. In this way, it can not only prevent groundwater from leaking into the basement, but also discharge groundwater, achieving the effect of "prevention and drainage combined", reducing the leakage risk of the basement wall-penetrating pipe, and solving the problem of leakage in the gap between the wall-penetrating pipe and the concrete structure of the basement in the prior art.
[0030] See also Figure 1 When the through-wall pipe 7 is an electric power or communication pipe, the through-wall pipe 7 gradually tilts downward from the first end to the second end. In this way, it is possible to effectively prevent groundwater from flowing back to the basement 5 along the through-wall pipe 7.
[0031] Preferably, the inclination gradient of the wall-penetrating pipe 7 is greater than or equal to 0.3%.
[0032] See also Figure 1 The construction process of the basement wall-penetrating pipe drainage waterproof structure is as follows:
[0033] (1) Backfill the side wall of the foundation pit to 30 cm below the bottom of the basement wall pipe 7, and backfill the soil layer by layer. Perform compaction tests on each layer to ensure that it meets the design and specification requirements.
[0034] (2) A 10 cm thick C15 concrete cushion layer 1 is poured close to the side wall of the basement 5. The plane size of the cushion layer 1 is 50 cm × (the outer wall width of the through-wall pipe + 10 cm).
[0035] (3) On the cushion layer 1 and along the six directions of the cuboid, a filter geotextile is laid as an isolation layer between the graded crushed stone and the backfill soil. The filter geotextile and the graded crushed stone form a water interception zone.
[0036] (4) Insert the first end of the drainage pipe 4 above the anti-filter geotextile, and connect the second end of the drainage pipe 4 to the municipal rainwater pipe well. Set the drainage pipe 4 with a longitudinal slope of not less than 0.3% from the interception area to the rainwater pipe well to facilitate drainage.
[0037] (5) Fill the interior of the geotextile with 20 cm of graded gravel. The graded gravel filling is synchronized with the backfill soil. The graded gravel and backfill soil are separated by geotextile.
[0038] (6) Install the basement through-the-wall pipe 7. When the through-the-wall pipe 7 is a drainage pipe for electricity or communication, a longitudinal slope of not less than 0.3% is set outward to prevent groundwater from flowing back into the basement 5 along the drainage pipe.
[0039] (7) After the through-wall pipe 7 is installed, continue to fill the graded gravel upwards according to the method (5) until it reaches 20 cm above the top of the through-wall pipe 7.
[0040] (8) Wrap the anti-filter geotextile tightly and wrap all the graded gravel in the anti-filter geotextile.
[0041] (9) Continue to backfill until the outdoor floor level is reached.
[0042] In summary, in this embodiment, the cushion layer 1 is placed below the wall-penetrating pipe 7, the permeable retaining layer 2 is in a closed state, the bottom of the permeable retaining layer 2 is placed on the cushion layer 1, the permeable retaining layer 2 isolates the permeable filling material 3 from the backfill soil, and the permeable retaining layer 2 and the permeable filling material 3 form a water interception area to intercept groundwater and prevent groundwater from entering the basement. Moreover, the groundwater seeps through the permeable filling material 3 to the bottom of the permeable retaining layer 2, and is then transported to the rainwater well through the drainage pipe 4. In this way, it can not only prevent groundwater from leaking into the basement, but also discharge groundwater, thereby achieving the effect of "combining prevention and drainage" and reducing the leakage risk of the wall-penetrating pipe in the basement.
