However, this structure has two defects: first, the new waterproof layer can only solve the leakage problem of the new side wall, but the new side wall structure still has uneven settlement, resulting in cracks at the connection between the wall structure of the new side wall and the structural wall of the existing side wall, which in turn causes leakage water to rush up along the cracks into the room; second, the new waterproof layer cannot fit the existing side wall, and a gap will be generated in the middle to cause the leakage water to rush up; and the waterproof layer encounters the problem of a broken wall at the existing side wall and the new side wall and the top plate, which are obvious leakage risk points, and there is no effective solution.

DETAILED DESCRIPTION

[0045] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are intended only to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of more restrictions, the elements defined by the sentence "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0046] The existing technology uses the external waterproofing and internal pasting method to deal with the leakage of the basement side wall, but the inventor found that the new side wall in the basement is a new structure, and there is still uneven settlement, which leads to cracks at the connection between the wall structure of the new side wall and the existing structure wall, and then causes leakage water to rush up along the cracks into the room. Secondly, the new waterproof layer cannot fit the existing side wall, and a gap will appear in the middle; coupled with the uneven settlement of the wall structure of the new side wall, the new side wall and the existing side wall will have relative displacement, so that a gap will appear between the new and old side wall structures, and the existing side wall itself has a leakage problem, forming a channel from the existing side wall and along the gap between the existing side wall and the new side wall to the basement. It can be seen that the new waterproof layer cannot solve the problem of leakage water rushing up along the gap between the new side wall and the existing side wall, and the new waterproof layer encounters the problem of broken wall between the existing side wall and the new side wall in the room, and the new side wall and the top plate are obvious leakage potential points at the broken position. In addition, when a new side wall is built on the inside of an existing side wall in a basement, there will be a load-bearing wall that cannot be removed, or a non-removable wall that changes from an exterior wall to an interior wall, or a man-air defense door. The new wall cannot penetrate the existing side wall, and the new waterproof layer cannot be closed, and can only break along with the break of the new side wall structure; and the new side wall is designed with an inner column at the break to anchor it to the existing side wall, but the new waterproof layer cannot enter the inner column at the break. The new waterproof layer cannot form an intersection with the structural wall, and groundwater can easily penetrate into the room along the existing side wall.

[0047] In order to solve the problems of the prior art, the embodiments of the present application provide a waterproof structural layer, a side wall waterproof structure and a construction method of the side wall waterproof structure.

[0048] In a first aspect, an embodiment of the present application provides a waterproof structural layer. Figure 1 The waterproof structural layer 4 includes: a first waterproof layer 41, covering the existing side wall 1, located between the existing side wall 1 and the newly built side wall 2, to the position of the inner wall column 3; a second waterproof layer 42, connected to the first waterproof layer 41, and the second waterproof layer 42 extends along the existing side wall 1, extends to the inner wall column 3, and extends away from the newly built side wall 2.

[0049] The waterproof structural layer of the embodiment of the present application is provided between the existing side wall and the newly built side wall to fill the gap between the existing side wall and the newly built side wall, thereby preventing leakage water from seeping into the room along the gap between the existing side wall and the newly built side wall; at the same time, the waterproof structural layer can block the leakage water from seeping into the room through the existing side wall itself, thereby better playing the role of waterproofing the side wall.

[0050] In an embodiment of the present application, the first waterproof layer is made of or includes a material that can bond well with the existing side wall and the newly built side wall and has a certain toughness, so as to adapt to the uneven settlement of the newly built side wall, so that the existing side wall and the newly built side wall maintain good integrity and waterproofness, avoid relative displacement between the existing side wall and the newly built side wall due to uneven settlement of the newly built side wall, and cause gaps, thereby preventing leakage water from seeping into the room through the gaps.

[0051] In some embodiments, Figure 1 and 2 The first waterproof layer 41 includes a waterproof mortar layer 410 and a waterproof roll material layer 411; the second waterproof layer 42 includes a waterproof mortar layer 410 and a rigid waterproof coating layer 420. The second waterproof layer is connected to the first waterproof layer, that is, the first waterproof layer 41 is connected to the waterproof mortar layer 410 of the second waterproof layer 42 through the waterproof mortar layer 410, and the waterproof mortar layer is respectively combined with the waterproof roll material layer and the rigid waterproof coating layer to form a waterproof structural layer covering the existing side wall, located between the existing side wall and the new side wall, and extending out of the wall column and extending away from the new side wall.

[0052] In some embodiments, Figure 1 , one end of the waterproof mortar layer 410 covers the existing side wall 1 between the existing side wall 1 and the newly made side wall 2, and the other end of the waterproof mortar layer 410 opposite to the one end extends toward the wall column 3 and is connected to the existing side wall 1; one end of the waterproof roll material layer 411 covers the waterproof mortar layer 410 and is set between the existing side wall 1 and the newly made side wall 2, and the other end of the waterproof roll material layer 411 opposite to the one end extends toward the wall column 3 and is sealed and connected to the existing side wall 1. Among them, one end of the waterproof mortar layer, that is, the waterproof mortar layer covers the part of the existing side wall set between the existing side wall and the newly made side wall, and the other end of the waterproof mortar layer, that is, the waterproof mortar layer covers the part of the existing side wall facing the wall column. Optionally, the other end of the waterproof mortar layer, that is, the waterproof mortar layer covers the part of the existing side wall to the groove. One end of the waterproof roll layer, i.e., the waterproof roll layer covers the waterproof mortar layer, which is located between the existing side wall 1 and the newly constructed side wall 2, and the other end of the waterproof roll layer, i.e., the waterproof roll layer covers the waterproof mortar layer, which extends toward the inner column of the wall and is sealed and connected to the existing side wall. Optionally, the other end of the waterproof roll layer, i.e., the waterproof roll layer covers the waterproof mortar layer and is sealed in the groove.

[0053] In some embodiments, Figure 3The waterproofing membrane layer 411 includes a first waterproofing membrane layer 4110 and a second waterproofing membrane layer 4111; the first waterproofing membrane layer 4110 is made of a non-asphalt-based strong cross-membrane self-adhesive polymer waterproofing membrane, and the second waterproofing membrane layer 4111 is made of a pre-laid butyl self-adhesive TPO polymer waterproofing membrane. For example, the first waterproofing membrane layer can use a non-asphalt-based strong cross-membrane polymer waterproofing membrane model APF-5000. The non-asphalt-based strong cross-membrane self-adhesive polymer waterproofing membrane is a double-sided self-adhesive waterproofing membrane, which plays the role of bonding the pre-laid butyl self-adhesive TPO polymer waterproofing membrane with the waterproof mortar on the existing side wall. At the same time, the non-asphalt-based strong cross-membrane self-adhesive polymer waterproofing membrane itself also serves as a waterproof structure to prevent water leakage. As part of the waterproofing membrane, the non-asphalt-based strong cross-membrane self-adhesive polymer waterproofing membrane has a break elongation of 200%, which can adapt to the relative displacement of the new side wall and the existing side wall due to uneven settlement, avoid the formation of seepage channels, and prevent the new side wall from causing cracks caused by the relative displacement of the new side wall and the existing side wall due to uneven settlement, causing the leakage water to rush into the room. The pre-laid butyl self-adhesive TPO polymer waterproofing membrane is used as the main waterproofing layer of the new side wall. There is no need to make a membrane protective layer on the new side wall. After the waterproofing structure layer is constructed, the steel bars can be directly tied to support the template, and the concrete can be poured to form the new side wall, completing the construction of the entire side wall waterproofing structure.

[0054] In some embodiments, the rigid waterproof coating layer 420 extends from the end connected to the first waterproof layer 41 along the existing side wall 1 to the wall column 3 and extends in a direction away from the newly constructed side wall 2, and the waterproof mortar layer 410 covers the rigid waterproof coating layer 420 and extends from the end connected to the first waterproof layer 41 to the wall column 3 and extends in a direction away from the newly constructed side wall 2.

[0055] In the embodiment of the present application, the waterproof mortar layer can use commercially available waterproof mortar with waterproof function, and can also preferably use KS-100X waterproof fiber waterproof mortar. The rigid waterproof coating layer can use special functional back water pressure waterproof coating to form a rigid waterproof coating layer firmly connected to the existing side wall. The waterproof mortar layer is used to form an anti-seepage measure for the existing side wall as a whole, blocking the leakage channel from the structural wall of the existing side wall to the interior.

[0056] In the process of improving the prior art, the inventors of the present application discovered that because the waterproofing coiled material layer of the newly constructed side wall continues to extend to the outside of the wall column between the existing side wall and the newly constructed side wall, water seepage and bulging may occur between the waterproofing coiled material layer and the existing side wall. In response to this problem, the present application replaces the waterproofing coiled material layer with a rigid waterproofing coating layer on the inner side of the newly constructed side wall where the wall column is connected to the existing side wall (i.e., the side where the newly constructed side wall is provided), to avoid water seepage and bulging between the external waterproofing coiled material layer where the wall column is connected to the existing side wall and the existing side wall. At the same time, the waterproofing structural layer of the present application, on both sides of the wall column where the existing side wall and the newly constructed side wall are connected, adopts a combination of closing the large surface of the waterproofing coiled material layer to the inside of the existing side wall and using a rigid waterproofing coating layer for transition, to form an integral waterproofing structural layer on the inner side of the existing side wall, thereby solving the problem of the waterproofing coiled material layer disconnecting the new side wall from the existing side wall.

[0057] In the embodiment of the present application, the distance that the second waterproof layer 42 extends from the existing side wall to the inner column 3 and away from the new side wall can be set according to the scope of leakage and spread of the existing side wall 1 in the room. In principle, the minimum requirement is to exceed the scope of leakage of the existing side wall. For example, the distance that the second waterproof layer 42 extends from the inner column 3 along the existing side wall 1 and away from the new side wall 2 is 0.5, 1, 1.5, 2.0, and 3 meters.

[0058] In a second aspect, an embodiment of the present application provides a side wall waterproof structure, such as Figure 1 As shown, it includes: a newly built side wall 2, which is arranged on the inner side of the existing side wall 1 along the extension direction L of the existing side wall 1, and the newly built side wall 2 is provided with an inner wall column 3 connected to the existing side wall 1, and the newly built side wall 2 is extended along the height direction H; a waterproof structural layer 4, which is arranged between the existing side wall and the newly built side wall; the waterproof structural layer 4 includes a first waterproof layer 41 and a second waterproof layer 42, and the first waterproof layer 41 covers the existing side wall 1 and is located between the existing side wall 1 and the newly built side wall 2 to the position of the inner wall column 3; the second waterproof layer 42 extends along the existing side wall 1 from the connection with the first waterproof layer 41 to the inner wall column 3, and extends in the direction away from the newly built side wall 2.

[0059] The side wall waterproof structure of the embodiment of the present application fills the gap between the existing side wall and the new side wall by setting a waterproof structural layer between the existing side wall and the new side wall, thereby preventing leakage water from flowing up into the room along the gap between the existing side wall and the new side wall; at the same time, the waterproof structural layer can block the leakage water from leaking into the room through the existing side wall itself, thereby better playing the role of waterproofing the side wall of the basement.

[0060] The side wall waterproof structure of the embodiment of the present application blocks the leakage water from rising along the gap between the existing side wall and the newly built side wall through the first waterproof layer of the waterproof structural layer, and prevents the leakage water from leaking into the room through the weak link between the existing side wall and the inner column through the second waterproof layer connected to the first waterproof layer and extending out of the wall column and extending in the direction away from the newly built side wall, and avoids the leakage water from leaking into the room through the existing side wall, so as to play a role of continuous waterproofing at the position of the inner column of the new side wall.

[0061] In an embodiment of the present application, the extension direction L of the existing side wall refers to the direction in which the side wall extends around the basement space or the ground indoor space. In some embodiments, the extension direction L of the existing side wall refers only to the direction along the straight surface or curved surface of the side wall of the basement space or the ground space. The newly made side wall is arranged on the inner side of the existing side wall along the extension direction L of the existing side wall to form a newly made side wall of a certain length. The height direction H refers to the direction in which the existing side wall or the newly made side wall extends from the bottom to the top around the basement space or the ground indoor space to form a three-dimensional existing side wall or the newly made side wall, so that the newly made side wall has a corresponding height.

[0062] In the embodiments of the present application, Figure 1 A groove 8 is provided on the side where the existing side wall 1 is connected to the new side wall 2 and adjacent to the inner wall column 3, and the groove 8 extends upward from the bottom of the existing side wall 1. It should be noted that the depth of the groove 8 provided on the existing side wall 1 is less than the distance from the surface of the existing side wall to the existing side wall structural steel bar, so as not to affect the strength of the existing side wall.

[0063] In some embodiments, Figure 1 , one end 41a of the first waterproof layer 41 is connected and extended along the first end 101 to the second end 102 of the existing side wall 1 and connected to the newly made side wall 2; the other end 41b of the first waterproof layer 41 opposite to the one end 41a is sealed in the groove 8; the second waterproof layer 42 is connected to the first waterproof layer 41 in the groove 8, and extends along the existing side wall 1 to the inner wall column 3 and away from the newly made side wall 2. The other end 41b of the first waterproof layer 41 is connected to the second waterproof layer 42. In the embodiment of the present application, by closing the other end 41b of the first waterproof layer 41 into the groove 8 of the existing side wall, the first waterproof layer 41 is better connected to the existing side wall 1, which plays a role in better sealing and waterproofing between the existing side wall 1 and the newly made side wall 2; the groove cooperates with the newly made side wall 2, and can tightly connect the first waterproof layer 41 between the existing side wall 1 and the newly made side wall 2, so as to better waterproof the existing side wall.

Optionally, the second waterproof layer 42 extends on the second side wall 110 to cover the area of ​​the existing side wall leakage as a minimum requirement, and can be set according to the leakage of the existing side wall at the construction site. Exemplarily, the second waterproof layer 42 extends on the second side wall 110 for more than 1 meter.

The third side wall 112 and the fourth side wall 113 are connected, and the inner wall column 3 is at least connected to the inner side of one side of the third side wall 112 and the fourth side wall 113 at the position of the dihedral angle α; one end 41a of the first waterproof layer 41 covers the space between the third side wall 112 and the newly made side wall 2; the other end 41b opposite to the one end 41a is sealed to the side where the third side wall 112 is connected to the newly made side wall 2 and is adjacent to the inner wall column 3; the second waterproof layer 42 extends from the connection with the first waterproof layer 41 along the third side wall 112 to the inner wall column 3 and extends to the fourth side wall 113 through the dihedral angle α; the first side wall 100 and the third side wall 112 are connected at the dihedral angle α, and the second side wall 110 and the fourth side wall 113 are connected at the dihedral angle α.

One end 41a of the first waterproof layer 41 covers between the first side wall 100 and the newly constructed side wall 2, and the other end 41b of the first waterproof layer 41 is connected to the newly constructed side wall 2 along the first side wall 100 and the third side wall 112 respectively and is sealed in the groove 8 adjacent to the side of the inner wall column 3; the second waterproof layer 42 extends from the connection with the first waterproof layer 41 along the first side wall 100 in the groove 8 to the inner wall column 3 and extends to the second side wall 110 through the dihedral angle α; the second waterproof layer 42 extends from the connection with the third waterproof layer 43 along the third side wall 112 in the groove 8 to the inner wall column 3 and extends to the fourth side wall 113 through the dihedral angle α, and the second waterproof layer 42 extends from the third side wall 112 to the fourth side wall 113 through the dihedral angle α to form an "L"-shaped structure. The first waterproof layer and the second waterproof layer are tightly connected to the existing side wall on the inner side of the existing side wall 1 with a dihedral angle, which can more effectively play a waterproof role and reduce the impact of cracks between the existing side wall and the new side wall caused by uneven settlement of the new side wall.

In the embodiment of the present application, the dihedral angle α also satisfies 0°<α<180° or 180°<α<360°.

[0083] In some embodiments, an outdoor waterproof layer 5 is provided along the water-facing surface 13 of the dihedral angle α region between the first side wall 100 and the third side wall 112, and an overlapping area 6 is provided on both sides of the first side wall 100 between the outdoor waterproof layer 5 and the waterproof structural layer 4 on the inner surface of the first side wall 100, and an overlapping area 6 is provided on both sides of the third side wall 112 between the outdoor waterproof layer 5 and the water-facing surface 13 of the third side wall 112 and the waterproof structural layer 4 on the inner surface of the third side wall 112. By arranging an outdoor waterproof layer 5 on the water-facing surfaces 13 of the first side wall 100 and the third side wall 112, the leakage positions of the water-facing surfaces 13 of the first side wall 100 and the third side wall 112 (i.e., the outdoor side of the existing side wall) are sealed and protected to prevent leakage water from leaking into the room along the first side wall 100 and the third side wall 112, and cooperate with the waterproof structural layer 4 on the indoor side of the first side wall 100 and the third side wall 112 and the newly built side wall 2 to form a waterproof structure that prevents leakage water from leaking into the room along the existing side wall itself and the gap between the existing side wall and the newly built side wall.

[0084] In some embodiments, the overlapping area 6 of the outdoor waterproof layer 5 along the water-facing surface 13 of the first side wall 100 and the waterproof structural layer 4 on the inner surface of the first side wall 100 on both sides of the first side wall 100 is more than 1 meter, and the overlapping area 6 of the outdoor waterproof layer 5 along the water-facing surface 13 of the third side wall 112 and the waterproof structural layer 4 on the inner surface of the third side wall 112 on both sides of the third side wall 112 is more than 1 meter. A certain overlapping area is formed on both sides of the existing side wall by the outdoor waterproof layer and the waterproof structural layer on the inner side of the existing side wall to prevent leakage water from leaking into the room through the existing side wall and the gap between the existing side wall and the new side wall.

[0085] In some embodiments of the present application, the inner side where the first side wall 100 and the second side wall 110 are connected is used to set the fire door 7; in the area inside the connection between the first side wall 100 and the third side wall 112, opposite to the outdoor waterproof layer 5, a third waterproof layer 43 is set along the second side wall 110 extending from the fire door 7 in a direction away from the first side wall 100, so as to further enhance the waterproof performance between the first side wall 100 and the fire door 7 through the third waterproof layer 43.

Optionally, the second waterproof layer 42 extends to the window frame where the fire door 7 is set, and one end of the third waterproof layer 43 extends from the window frame where the fire door 7 is set to the fourth side wall 113 through the dihedral angle α.

[0086] The inventor of the present application found that, because the newly constructed side wall is a newly constructed structure, the top plate connected to the existing side wall has no new waterproof layer, and the overall waterproof layer between the existing side wall and the top plate is in an unclosed state, that is, a complete waterproof structure has not been formed. Groundwater or seepage water is easy to leak along the unclosed parts of the newly constructed coiled material, the roughened parts of the interface, and the unpoured parts of the newly constructed side wall concrete, resulting in potential leakage indoors. In response to this, the inventor of the present application has made corresponding improvements to the leakage problem between the newly constructed side wall and the top plate on the basis of improving the waterproof structure of the side wall.

[0087] In some embodiments, Figure 8 and 9A groove 8 is provided at the connection between the existing side wall 1 and the top plate 9 along the extension direction L of the existing side wall 1; one end of the waterproof structural layer 4 extending upward along the existing side wall 1 is sealed in the groove 8 and sealedly connected to the top plate 9; the new side wall 2 is sealedly connected to the top plate 9.

[0089] In some embodiments, Figure 8 and 9 The waterproof structural layer 4 is mechanically fixed at one end in the groove 8 by a pressure strip 14, and the end is sealed by a sealing paste 15 and a waterproof mortar 16 to prevent water from leaking into the room through the gap between the waterproof structural layer 4 and the top plate 9. Fig.10 The joint between the newly made side wall 2 and the top plate 9 is sealed and connected by a sealing waterproof coating layer 10. The sealing waterproof coating layer can be made of cement-based penetrating crystalline waterproof coating. Figure 8 and 10 A grouting pipe 11 is buried at the connection between the new side wall 2 and the top plate 9, so that a sealing waterproof coating is poured into the connection between the new side wall 2 and the top plate 9 through the grouting pipe to form a sealing waterproof coating layer 10. Optionally, the grouting pipe 11 is arranged on the outside of the groove 8, so that the grouting pipe 11 is buried at the connection between the new side wall 2 and the top plate 9. After the settlement of the new side wall 2 is completed, the grouting pipe 11 can be grouted between the new side wall 2 and the top plate 9 through the grouting pipe 11, and the structural gap between the new side wall and the top plate is filled to block the channel of the leaking water. A drainage channel 12 is arranged at the connection between the new side wall 2 and the top plate 9, so that the leaking water that may be generated through the gap between the waterproof structural layer 4 and the top plate 9 is discharged through the drainage channel 12 reserved for drainage, so as to prevent the leaking water from infiltrating into the room. Optionally, the drainage channel 12 is arranged on the outside of the grouting pipe 11. The drainage channel 12 can be formed by burying a pipeline, or placing a mold to form a drainage trough when pouring concrete to form a new side wall as the drainage channel 12. The drainage vertical pipe connected to the drainage channel 12 can be arranged according to the position of the sump for drainage on site.

[0090] The side wall waterproof structure of the embodiment of the present application adopts a method of roughening the connection between the top plate and the newly built side wall and applying a sealing waterproof coating, burying a grouting pipe, and setting a drainage channel, that is, a method of combining blocking the leakage water with discharging the leakage water is adopted to prevent the connection between the new side wall and the top plate from leaking due to the failure to form a complete waterproof structure.

[0091] In a third aspect, the present application also provides a construction method for a side wall waterproof structure, such as Figure 1 , including: a first waterproof layer 41 covering the existing side wall 1 is arranged along the inner side of the existing side wall 1 from the first end 101 to the second end 102; a second waterproof layer 42 connected to the first waterproof layer 41 and away from the first waterproof layer 41 is arranged along the inner side of the existing side wall 1 from the second end 102 to the third end 103, and the first waterproof layer 41 and the second waterproof layer 42 form a waterproof structural layer 4; a new side wall 2 is arranged along the first waterproof layer 41; and an inner wall column 3 connected to the existing side wall 1 is arranged at the connection between the second waterproof layer 42 and the first waterproof layer 41.

[0092] In an embodiment of the present application, the third end, i.e., the end of the second waterproof layer extending out of the wall column along the existing side wall and away from the first waterproof layer, can be set according to the scope of leakage and spread of the leaking water in the existing side wall.

[0093] The construction method of the side wall waterproof structure of the present application is to fill the gap between the existing side wall and the new side wall by arranging a waterproof structural layer including a first waterproof layer and a second waterproof layer on the inner side of the existing side wall, and arranging a new side wall connected to the first waterproof layer along the waterproof structural layer, and an inner wall column connected to the existing side wall, so as to prevent leakage water from flowing up into the room along the gap between the existing side wall and the new side wall; at the same time, the waterproof structural layer can prevent leakage water from leaking into the room through the existing side wall itself, thereby better playing the role of waterproofing the side wall.

[0094] In some embodiments, the construction method of the side wall waterproof structure further includes: performing surface treatment on the existing side wall 1. By performing surface treatment on the existing side wall 1 by removing or chiseling the plaster layer or the finishing layer on the surface, the structural wall surface of the existing side wall can be tightly connected with the waterproof structural layer. Optionally, performing surface treatment on the existing side wall further includes spraying water on the surface of the existing side wall for wetting treatment so as to more firmly combine with the waterproof mortar.

[0095] In some embodiments, the construction method of the side wall waterproof structure further includes: a groove extending upward from the bottom is formed on the inner side of the existing side wall along the second end 102 of the existing side wall, so that the other end 41b of the first waterproof layer can be better sealed in the existing side wall 1, preventing the leakage water from leaking into the room along the first waterproof layer and the existing side wall.

[0096] In some embodiments, a first waterproof layer 41 covering the existing side wall 1 is provided along the first end 101 to the second end 102 of the inner side of the existing side wall 1, including: coating waterproof mortar along the inner side of the existing side wall from the first end 101 to the second end 102 to cover the existing side wall 1, forming a waterproof mortar layer 410; and providing a waterproof roll material layer 411 along the waterproof mortar layer 410 from the first end 101 to the second end 102 and sealingly connecting it to the existing side wall 1, forming a first waterproof layer 41. The first waterproof layer seals and waterproofs the area where the existing side wall with leakage is connected to the new side wall, and prevents the leakage water from flowing up into the room along the cracks due to the uneven settlement of the new side wall, which causes cracks between the new side wall and the existing side wall.

[0097] In some embodiments, the second waterproof layer 42 connected to the first waterproof layer 41 and away from the first waterproof layer 41 is provided along the inner side of the existing side wall 1 from the second end 102 to the third end 103, including: coating the rigid waterproof coating along the existing side wall 1 from the second end 102 to the third end 103 to form a rigid waterproof coating layer 420; coating the waterproof mortar along the rigid waterproof coating layer 420 from the second end 102 to the third end 103 to form a waterproof mortar layer 410 connected to the waterproof mortar layer 410 of the first waterproof layer 41. The second waterproof layer 42 is composed of a rigid waterproof coating layer and a waterproof mortar layer.
