[0027] The cross section of the waterproof liner 13 is U-shaped.
[0028] The drainage portion 17 is a drainage ditch or a water collection well.
[0029] In a possible embodiment, a water repellent 14 is provided on the outer wall 23 within a height range of 600 mm above the ground outdoors. The water repellent 14 is connected to the gel body 11 . The water repellent 14 , the gel body 11 and the bottom plate 21 together form a waterproof closure.
[0030] In a possible embodiment, the gel 11 is formed by solidifying an organic chemical grouting material, and the organic chemical grouting material is an acrylate or polyurethane slow-setting water-blocking grouting material.
[0031] Please combine Figure 2 As shown, in a possible embodiment, the base plate 21 includes a non-reinforced concrete plate 212 and a plain concrete cushion layer 213.

The paint layer 12 is applied on the surface of the plain concrete cushion layer 213, the surface of the inner wall 22 and the surface of the outer wall 23 away from the soil layer 3.
[0032] In this embodiment, the non-reinforced concrete slab 212 may be mortar.
[0033] Please combine Figure 3 As shown, in a possible embodiment, the base plate 21 includes a reinforced concrete plate 211 , and a coating layer 12 is applied on the reinforced concrete plate 211 , the bottom of the inner wall 22 , and the surface of the outer wall 23 away from the soil layer 3 .
[0034] In a possible embodiment, the coating layer 12 is a cement-based penetrating crystalline waterproof coating.
[0035] In a possible embodiment, the waterproof liner 13 includes reinforced waterproof fine stone concrete formed by casting, and the reinforced waterproof fine stone concrete is arranged on the surface of the coating layer 12 .
[0036] In a possible embodiment, the waterproof liner 13 further includes a shear key 15, which is respectively arranged at the root of the inner wall 22 and the root of the outer wall 23, and the shear key 15 is inserted into the masonry structure basement 2 from the reinforced waterproof fine stone concrete.
[0037] In this embodiment, when the underground water level rises, the shear key 15 is used to prevent the buoyancy of water from lifting the waterproof liner 13, thereby preventing the waterproof liner 13 from being separated from the masonry.
[0038] In a possible embodiment, the waterproof liner 13 further includes shear reinforcement 16 , and the shear reinforcement 16 includes tension reinforcement 161 and anchor reinforcement 162 . The tension reinforcement 161 is provided on the inner wall 22 , and the anchor reinforcement 162 is provided on the outer wall 23 .
[0039] The waterproof system 1 for the masonry structure basement of this embodiment includes a first waterproof treatment, a second waterproof treatment and a third waterproof treatment. The first waterproof treatment: fill the grouting material between the outer wall 23 and the soil layer 3, and form a gel 11 after solidification; the second waterproof treatment: when the bottom plate 21 is a reinforced concrete plate 211, a coating layer 12 is applied on the surface of the bottom plate 21, the inner wall 22 and the outer wall 23 away from the soil layer 3; when the bottom plate 21 is a non-reinforced concrete plate 212, a plain concrete cushion layer 213 is provided on the surface of the bottom plate 21, and a coating layer 12 is applied on the surface of the plain concrete cushion layer 213, the inner wall 22 and the outer wall 23 away from the soil layer 3; the third waterproof treatment: a waterproof liner 13 is provided on the surface of the coating layer 12, and the waterproof liner 13 is fixedly connected to the masonry structure basement 2.
[0040] Specifically, the first waterproofing treatment includes the following steps: cleaning the inner surface of the outer wall 23; drilling a hole on the inner surface of the outer wall 23, the hole penetrating to the outer surface of the outer wall 23; installing a grouting pipe into the hole with a rubber hammer, and sealing the gap between the grouting pipe and the hole wall with a quick-hardening admixture; injecting the grouting material from the inner side of the outer wall 23 to the outer side of the outer wall 23 under high pressure through the grouting pipe, and the order of injecting the grouting material is from the bottom of the outer side of the outer wall 23 to the top of the outer side of the outer wall 23, and from the outer side of the outer wall 23 along the horizontal direction of the outer side of the outer wall 23. Push from one end to the other end, open multiple holes, and set the multiple holes at intervals. The next hole opening position is used to judge whether the current position is full of grouting material. When the pressure on the pressure gauge of the grouting machine increases significantly or the grouting material overflows from the next hole opening position, it means that the current position is full of grouting. At this time, stop the pressure grouting and change to the next grouting hole. After the organic chemical grouting material in the grouting hole is solidified, take out the grouting pipe and seal the hole with a quick-hardening external admixture. Scrape off the organic chemical grouting material on the base of the brick wall to keep the surface of the brick wall flat.
[0041] The second waterproofing treatment includes the following steps: after cleaning and leveling the inner side of the outer wall 23, the two sides of the inner wall 22 and the surface of the bottom plate 21, the second waterproofing treatment is performed according to the condition of the bottom plate 21. The bottom plate 21 is divided into two cases: the first case is that the bottom plate 21 includes a reinforced concrete slab 211; the second case is that the bottom plate 21 includes a non-reinforced concrete slab 212 and a plain concrete cushion layer 213, and the non-reinforced concrete slab 212 is made of mortar or other materials. In the first case, a cement-based penetrating crystalline waterproof coating is evenly applied on the inner side of the outer wall 23, the two sides of the inner wall 22 and the surface of the bottom plate 21, and the coating is left to dry. In the second case, after the plain concrete cushion layer 213 is first cast on the non-reinforced concrete slab 212, a cement-based penetrating crystalline waterproof coating is evenly applied on the inner side of the outer wall 23, the two sides of the inner wall 22 and the surface of the bottom plate 21, and the coating is left to dry.
[0042] The third waterproofing treatment includes the following steps: at the bottom of the inner wall 22 and the bottom of the outer wall 23, a small amount of masonry is chiseled off at a certain interval, and steel supports are placed in the chiseled area; bidirectional steel bars are laid on the inner side of the outer wall 23, on both sides of the inner wall 22, and on the surface of the bottom plate 21; fine stone concrete is poured at the bottom of the inner wall 22, the bottom of the outer wall 23, and the bottom plate 21, and then the concrete is vibrated to make it dense and then cured; formwork is supported on the inner side of the outer wall 23 and on both sides of the inner wall 22, and fine stone concrete is poured, and then the concrete is vibrated to make it dense and then cured.
[0043] Furthermore, the construction method of the waterproof system 1 for a masonry structure basement also includes drainage treatment: a drainage portion 17 is provided in the waterproof inner liner 13 , and the drainage portion 17 is used to discharge sewage in the waterproof inner liner 13 .
[0044] The implementation principle of the waterproof system 1 for a masonry structure basement in this embodiment is:
[0045] The gel 11, the base plate 21 and other water-repellent measures together serve as the first waterproof layer. The inner wall 22, the outer wall 23 and the back surface of the concrete base plate 21 are coated with a cement-based penetrating crystalline waterproof coating. The silicate ions dissolved in the cement-based penetrating crystalline waterproof coating penetrate and diffuse in the masonry (or concrete) along with the surface water, and react chemically with the calcium ions in the masonry (or concrete) to produce water-insoluble calcium silicate hydrates, and then form dendrite-like crystals. Once the cement-based penetrating crystalline waterproof material encounters water, it can continuously produce chemical reactions. The generated crystals are combined with the masonry (or concrete) into a whole, and the pore channels inside the masonry (or concrete) are continuously filled, so that the masonry is gradually dense, forming a second waterproof layer. As the third waterproof layer, the U-shaped waterproof liner 13 is made of reinforced fine stone concrete cast in situ, which further prevents water seepage in the masonry structure basement 2. Shear reinforcement 16 and shear key 15 are arranged between the waterproof liner 13 and the masonry structure basement 2, so that the new and old structures work together, thereby enhancing the integrity and bearing capacity of the foundation of the masonry structure basement 2.
[0046] In summary, the advantages of waterproof system 1 for masonry basements are:
[0047] (1) Good waterproofing effect: By adopting targeted waterproofing measures on the water-facing and water-receiving surfaces of the masonry structure basement 2, and adding reinforced concrete waterproof liner 13 structure and drainage measures, a "three-proof and one-drain" waterproofing system 1 for the masonry structure basement is formed, which significantly improves the overall waterproofing effect of the basement.
[0048] (2) Simple construction, wide applicability, and strong operability: The waterproof system 1 for masonry basements is suitable for the waterproof upgrade and renovation of most masonry basements. Especially for basements with complex underground pipe networks and a small distance from temporary buildings, if outdoor excavation is used to apply waterproof coatings on the water-facing surface, the construction will be difficult and the construction period will be long. Improper handling may even cause safety hazards. The waterproof system 1 for masonry basements avoids outdoor excavation. By drilling holes from the indoor to the outdoor of the masonry basement 2, acrylate (or polyurethane) slow-setting water-blocking grouting material is injected into the hole under high pressure, forming a water-stopping isolation layer on the water-facing surface of the outer wall 23 of the masonry basement 2, which greatly reduces the construction difficulty and shortens the construction period.
[0049] (3) It has both structural reinforcement effect and improves structural safety: Considering that the structural load will increase to a certain extent due to the need for the later use of the upper building during the renovation of the entire building, higher requirements are often placed on the bearing capacity of the masonry structure basement 2. On the other hand, due to long-term water leakage and waterlogging, the structural strength and durability of the masonry structure basement 2 have also been significantly weakened, posing certain safety hazards. Therefore, during the waterproof renovation and upgrading of the masonry structure basement 2, by adding a reinforced concrete waterproof liner 13, not only can the risk of water leakage and waterlogging be more effectively reduced, but also the structural durability can be improved, and the integrity and bearing capacity of the foundation can be significantly improved.
[0050] The above implementation modes are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
