For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The embodiment of the utility model provides a waterproof and anti-seepage structure and building, in which the waterproof consolidation slurry part, the flexible sealing slurry part and the structure are consolidated into one, which meets the requirements of three-dimensional structural protection and ensures the reliability and durability of the building structure.

[0029] Combine the following Figure 1-Figure 3The technical solution provided by the utility model is described in more detail.

[0030] like Figure 1 As shown, the waterproof and anti-seepage structure provided by the utility model includes a structure 1, a waterproof consolidation slurry part 4 and a flexible sealing slurry part 5, wherein: a first channel 2 and a second channel 3 are arranged in the structure 1, the first channel 2 connects the back water side and the front water side of the structure 1, and the waterproof consolidation slurry part 4 is filled in the first channel 2 and the front water side of the structure 1; the second channel 3 connects the back water side of the structure 1 and the joint 101 (such as Figure 1 and Figure 2 ), or the second channel 3 connects the backwater side of the structure 1 with the bulging crack 102 of the structure 1 (such as Figure 3 ), the flexible sealing slurry portion 5 is filled in the second channel 3, the joint seam 101 of the structure 1 or the bulging and cracking portion 102 of the structure 1.

[0031] The waterproof consolidation slurry of this embodiment is the YYG consolidation slurry (also known as RD-502 underwater fast-hardening anti-seepage reinforcement slurry) in the prior art, which is an inorganic grouting material specially used in water environment, or the RD-AM slurry in the prior art, which is a new type of acrylic resin curtain waterproof grouting material with a slight acidic smell and no other irritating smell. Alternatively, the waterproof consolidation slurry is a mixture of the YYG consolidation slurry and the RD-AM slurry. The "waterproof consolidation slurry part 4" is a structural layer 106 formed by the above-mentioned material filling the first channel 2 and the water-facing side of the structure 1.

[0032] The flexible sealing slurry of this embodiment is the RD-R flexible sealing slurry in the prior art. The "flexible sealing slurry portion 5" is a structural layer 106 filled with the RD-R flexible sealing slurry in the second channel 3 and the joint 101, or the bulging and cracking part 102 of the second channel 3 and the structure 1.

[0033] See also Figure 1 As shown, the above-mentioned "backwater side" refers to the side A in the figure, and the "frontwater side" refers to the side B in the figure. For the basement, water seepage usually occurs underground. Therefore, the backwater side refers to the side of the structure 1 facing the basement room, and the frontwater side refers to the underground side of the structure 1.

[0034] In the waterproof and anti-seepage structure of this embodiment, the waterproof consolidation slurry is squeezed into the water-facing side of the structure 1 through the first hole 2, forcibly filling and occupying the water storage space, and the water and air on the water-facing side of the structure 1 are squeezed out through the first hole 2 to form a waterproof consolidation slurry part; the flexible sealing slurry is squeezed into the joint seam 101 and the bulging crack 102 of the structure 1 through the second hole 3, and the water and air in the joint seam 101 and the bulging crack 102 are squeezed out through the second hole 3 to form a flexible sealing slurry part 5. The waterproof consolidation slurry part 4 and the flexible sealing slurry part 5 are consolidated with the structure 1 as a whole, meeting the requirements of three-dimensional structural protection and ensuring the reliability and durability of the building structure.

[0035] As an optional implementation, the number of the first channels 2 is one or at least two. When the number of the first channels 2 is more than two, the first channels 2 are distributed in a matrix on the structure 1 .

[0036] When the number of the first channels 2 is two or more, a waterproof consolidation slurry portion 4 can be quickly formed on the water-facing side of the structure 1, thereby improving construction efficiency.

[0037] See also Figure 1 As shown, in this embodiment, the waterproof and anti-seepage structure is applied to the water leakage of the tower crane foundation and the joint 101 of the structure 1.

[0038] The waterproof and anti-seepage structure also includes a water-stopping steel plate 6, which connects two adjacent structures 1. The above structure can tighten the two structures 1 to improve the waterproof effect.

[0039] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the second channel 3 connects the backwater side of the structure 1 and the joint 101 between the connected structures 1, and the flexible sealing slurry part 5 is filled on the upper and lower sides of the water-stopping steel plate 6.

[0040] The joint seam 101 of the structure 1 is prone to water seepage. Therefore, in this embodiment, the flexible sealing slurry part 5 is filled at the joint seam 101 and in the second channel 3 through the second channel 3, which can improve the waterproof effect and prevent groundwater from seeping out from the joint seam 101.

[0041] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the waterproof and anti-seepage structure further includes a waterproof slurry layer 7 , which is located on the backwater side of the structural layer 106 and covers the joint seam 101 between two adjacent structural bodies 1 .

[0042] The waterproof slurry layer 7 is any waterproof slurry in the prior art, which can form the last waterproof barrier on the back-water side surface of the structure 1 to improve the waterproof effect.

[0043] Figure 3 The structure of the flexible sealing slurry part 5 at the joint seam 101 of the structure 1 and the second channel 3 is shown in FIG.

[0044] Embodiment 2:

[0045] In this embodiment, the waterproof and anti-seepage structure is applied to the overall curtain of the basement.

[0046] See also Figure 1 As shown, the structure 1 in this embodiment includes, from top to bottom, a structural layer 106 (the structural layer 106 is the base of the structural body 1), a waterproof layer 105, a cushion layer 104, a waterproof consolidation slurry, and a backfill layer 103. Among them, the structural layer 106, the waterproof layer 105, the cushion layer 104 and the backfill layer 103 are the existing structural layer 106 of the basement.

[0047] The waterproof consolidation slurry layer is a structural layer 106 formed by filling the waterproof consolidation slurry part 4 on the water-facing side of the cushion layer 104 .

[0048] join Figure 1 As shown, when water seepage occurs at the underground roots of the pedestal column 9, the backwater side of the structure 1 and the bulging and cracking part 102 of the structure 1 (the pedestal column 9, which is a part of the structure 1) are connected through the second channel 3, so that the flexible sealing slurry part 5 is filled in the second channel 3 and the bulging and cracking part 102 of the structure 1.

[0049] See also Figure 1 As shown, the backwater side and the frontwater side of the structure 1 (specifically, the frontwater side is the frontwater side of the cushion layer 104 ) are connected through the first channel 2 , so that the waterproof consolidation slurry part 4 is filled to form the first channel 2 and the frontwater side of the structure 1 .

[0050] The difference between this embodiment and embodiment 1 is that the waterproof and anti-seepage structure further includes a flash-setting slurry portion, and the flash-setting slurry portion 8 is filled at the root of the pedestal column 9 and is flush with the back-water side surface of the structure 1 .

[0051] The flash setting slurry part 8 can be a structure formed by YY-16 flash setting slurry. The flash setting slurry part 8 is filled in the root of the foundation column 9, which can prevent groundwater from seeping out from the root of the foundation column 9.

[0052] As an alternative embodiment, see Figure 3 As shown, the waterproof slurry layer 7 is located on the backwater side of the structural layer 106 , and the waterproof slurry layer 7 covers the root of the foundation column 9 .

[0053] As an optional embodiment, the thickness of the flash setting slurry portion is 5-10 cm.

[0054] As an optional embodiment, the thickness of the waterproof slurry layer 7 is 2-5 mm.

[0055] In this embodiment, the waterproof consolidation slurry part 4, the flexible sealing slurry part 5 and the structure 1 are consolidated into one, meeting the requirements of three-dimensional structural protection and ensuring the reliability and durability of the building structure.

[0056] This embodiment provides a building, including a structure 1 and the above-mentioned waterproof and anti-seepage structure. The building is particularly suitable for a basement building, such as an underground garage.

[0057] In this embodiment, the problem of water seepage in the basement of a high-rise building can be solved by solving the problems of water seepage and water storage cavities, inhibiting or reducing the buoyancy damage caused by water, and reliably and durably solving the problem of floating water on the structure.

[0058] Taking the basement building as an example, in order to reduce the penetration of groundwater into the underground garage, the first channel 2 and the second channel 3 are set along the bottom plate and construction joints of the treatment range for space replacement grouting. The grouting depth reaches the spatial cavity of the water-facing surface of the bottom plate. The first channel 2 is spaced 1.5-2m apart. The grouting holes are arranged in a plum blossom shape with a row spacing of 1.5-2m. The grouting pressure is 0.5-0.8Mpa.

[0059] Grouting construction of waterproof consolidation slurry part 4 and flexible sealing slurry part 5 usually adopts the grouting method of "injection one by one, injection first and then blocking". It is different from the "jump injection" method of traditional chemical grouting. When grouting is arranged along both sides of the crack, the crack generally does not need to be closed, and special cases are analyzed specifically. Continuous grouting should at least ensure the continuity of grouting within an operating time period in a receiving area. For large-area multi-porous grouting, it is gradually promoted layer by layer in the order of first the periphery and then the interior. After the last first channel 2 or second channel 3 changes from clear water → turbid water → slurry, do not seal it immediately. Continue to fill in this grouting hole to ensure that the first channel 2 or second channel 3 adjacent to it is also full of slurry.

[0060] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0061] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
