The limiting structure 3 includes a U-shaped groove 31, an inclined side 32 and a through hole. The U-shaped groove 31 is embedded inside the surface of the edge of the base surface 1. The inclined side 32 is arranged on the side wall at one end of the U-shaped groove 31. The through hole is arranged on the inner bottom surface at the corner of the U-shaped groove 31; a drainage structure 4, and the drainage structure 4 is installed inside the U-shaped groove 31. The drainage structure 4 includes a drain pipe 41 and an interface 42. The drain pipe 41 penetrates through the inside of the U-shaped groove 31 through the through hole. The interface 42 is arranged on the side wall of the drain pipe 41; a waterproof structure 5, and the waterproof structure 5 is laid on the surface of the base surface 1 and the inner surface of the secondary structural wall 2. The waterproof structure 5 includes a waterproof coiled material 51, and the waterproof coiled material 51 is laid on the surface of the base surface 1 and the inner surface of the secondary structural wall 2; a cover plate 6, and the cover plate 6 is fixed on the top surface of the secondary structural wall 2.
[0022] In the specific implementation process, such as Figure 1 , Figure 3 and Figure 4As shown, the drainage structure 4 further includes a drain pipe 43, a drain net 44, and a geotextile 45. One end of the drain pipe 43 is installed on the side wall of the drain pipe 41 through the interface 42. The drain net 44 is installed on the inner side wall at the top end of the drain pipe 41. The geotextile 45 is wound around the side wall of the drain pipe 43. One end of the drain pipe 43 is internally connected to the drain pipe 41 through the interface 42. The side wall of the drain pipe 43 is provided with round holes, and the round holes are only provided on the side wall of the upper end of the drain pipe 43. The bottom end of the drain pipe 43 is wrapped by the waterproof coiled material 51.
[0023] It is convenient to wrap the side wall of the drain pipe 43 with the geotextile 45 so that the round holes provided on its surface will not be blocked when the concrete layer 52 is poured on the surface, and the rainwater isolated by the waterproof coiled material 51 can be collected and discharged through the round holes provided on its surface, enabling the rainwater absorbed in the concrete layer 52 to be quickly discharged.
[0024] In the specific implementation process, as Figure 1 and Figure 4 shown, the waterproof structure 5 further includes a concrete layer 52 and a slope 53. The concrete layer 52 is poured on the surface of the waterproof coiled material 51. The slope 53 is provided at the edge of the joint between the base surface 1 and the secondary structural wall 2. The concrete layer 52 completely covers the surface of the waterproof coiled material 51. The thickness of the concrete layer 52 is greater than the distance between the interface 42 and the drain net 44. The top end position of the drain pipe 41 is slightly lower than the surface height of the slope 53. The slope 53 is provided at the edge of the base surface 1, and the slope 53 is directly above the position of the drain pipe 43.
[0025] The waterproof effect of the construction joint between the secondary structural wall 2 and the base surface 1 is strengthened by the waterstop plate 8. Through the setting of the slope-forming layer, a certain gentle slope is formed at the edge of the base surface 1 by the slope 53 to facilitate the collection of rainwater. The U-shaped groove 31 is provided at the included angle between the secondary structural wall 2 and the base surface 1. Through the radian inside the U-shaped groove 31 and the inclined side 32 at one end, the laying of the waterproof coiled material 51 can be facilitated, preventing rainwater from directly contacting the root of the secondary structural wall 2.
[0026] In the specific implementation process, as Figure 1 、 Figure 2 and Figure 4As shown, one end of the U-shaped groove 31 is flush with the base surface 1, and the other end of the U-shaped groove 31 is higher than the height of the base surface 1. The other end of the U-shaped groove 31 blocks the joint between the base surface 1 and the secondary structural wall 2. The other end of the U-shaped groove 31 delays the slope with the secondary structural wall 2 through the inclined side 32. The waterproof coiled material 51 is laid in a U shape inside the U-shaped groove 31.

[0028] The working principle of the secondary structure anti-seepage and anti-leakage structure provided by the present utility model is as follows:
[0029] During use, when initially constructing the primary structure of the base surface 1, the water stop plate 8 is pre-embedded at the position of the secondary structure wall 2. And according to the thickness of the secondary structure wall 2, the U-shaped groove 31 is pre-embedded at the edge position of the base surface 1 in accordance with the thickness of the secondary structure wall 2, so that one end inside the U-shaped groove 31 is flush with the base surface 1, and the other end is slightly higher than the base surface 1. The water stop plate 8 is vertically pre-embedded at the position on the surface of the edge of the base surface 1, and its position is at the midpoint of the thickness of the secondary structure wall 2, making the water stop plate 8 become the water stop partition between the secondary structure wall 2 and the base surface 1, further strengthening the measure for the joint of new and old concrete due to the non-compact concrete pouring. When constructing the secondary structure wall 2, its inner sidewall is built closely against the sidewall of one end of the U-shaped groove 31, and the surface of the joint between the base surface 1 and the secondary structure wall 2 is roughened. Then the secondary structure wall 2 is constructed, so that the two construction surfaces of the secondary structure wall 2 and the base surface 1 can be firmly bonded through the roughened joint 7. Then the waterproof coiled material 51 is laid on the surface of the base surface 1 and the inner surface of the secondary structure wall 2. The inclined side 32 of one end of the U-shaped groove 31 can slow down the angle at which the waterproof coiled material 51 is pasted on the wall of the secondary structure wall 2. Through the radian of the inner sidewall of the U-shaped groove 31, the included angle between the secondary structure wall 2 and the base surface 1 is mitigated, so that when the waterproof coiled material 51 is laid at the included angle, the connection between its two ends and the base surface 1 and the secondary structure wall 2 can be made smoother, thus preventing the phenomenon of stress concentration and preventing rainwater from directly contacting the root of the secondary structure wall 2. The waterproof coiled material 51 can wrap the top surface of the secondary structure wall 2. Then the cover plate 6 is covered on the top surface of the secondary structure wall 2 to fix the edge of the laid waterproof coiled material 51. Then the drain pipe 41 is installed through the through hole, so that one end of the drain pipe 43 is connected to the drain pipe 41 through the interface 42. Then its surface is wound with the geotextile 45, making the end of the drain pipe 43 with round holes face upward, and it is placed inside the U-shaped groove 31, so that the waterproof coiled material 51 wraps the bottom end of the drain pipe 43. The waterproof coiled material 51 wraps the lower sidewall position of the interface 42 provided on the sidewall of the drain pipe 41 to seal the gap between the drain pipe 41 and the through hole. Then the concrete layer 52 is laid on the surface of the waterproof coiled material 51 to seal the waterproof coiled material 51. The concrete layer 52 at the included angle between the secondary structure and the base surface 1 is provided with the slope 53, making the edge plane of the base surface 1 lower than other planes, so that rainwater can be collected and discharged through the slope 53. This structure has the function of strengthening the interfacial connection force between new and old concrete,The advantage of preventing leakage at the connection between the secondary structure and the primary structure.
[0030] Compared with the related technologies, the anti-seepage and leakage-preventing structure of the secondary structure provided by the present utility model has the following beneficial effects:
[0031] The present utility model provides an anti-seepage and leakage-preventing structure for a secondary structure. When constructing the base surface 1, first, according to the thickness of the secondary structure wall 2, in order to avoid water leakage at the construction joint, the water stop plate 8 is vertically embedded inside the edge of the surface of the base surface 1 at the mid-thickness of the wall. At the same time, according to the position of the thickness of the secondary structure wall 2, the limiting structure 3 is pre-embedded on the surface of the base surface 1, with its inner end flush with the base surface 1 and its other end higher than the height of the base surface 1. Then, the surface of the secondary structure wall 2 constructed on the edge of the base surface 1 is roughened, so that when constructing the secondary structure wall 2, the roughening can strengthen the bonding firmness of the construction surfaces in two construction stages. At the same time, the water stop plate 8 can further prevent the measure of strengthening water stop due to the non-compact pouring of concrete at the joint of new and old concrete. Then, the waterproof coiled material 51 in the waterproof structure 5 is laid on the inner side of the secondary structure wall 2 and the surface of the base surface 1. When the waterproof coiled material 51 is laid at the angle between the secondary structure wall 2 and the base surface 1, the angle between the secondary structure wall 2 and the base surface 1 is mitigated through the radian of the inner side wall of the limiting structure 3, so that when the waterproof coiled material 51 is laid at its angle, the connection between its two ends and the base surface 1 and the secondary structure wall 2 can be made smoother, facilitating the laying of the waterproof coiled material 51. Then, the drainage structure 4 is installed inside the limiting structure 3, so that the waterproof coiled material 51 wraps the bottom end of the drainage structure 4 and seals the gap between the drainage structure 4 and the limiting structure 3. Then, concrete is laid according to the height of the strainer 44, and the waterproof coiled material 51 is sealed inside the concrete layer 52, thereby preventing the phenomenon of air bubbles appearing inside due to temperature difference and time change. The edge of the waterproof coiled material 51 is sealed and fixed by the cover plate 6, so that the edge of the waterproof coiled material 51 will not be debonded and warped. This structure has the advantage of strengthening the interfacial connection force between new and old concrete and preventing leakage at the connection between the secondary structure and the primary structure.
