Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building waterproof design, in particular to a rigid composite waterproof structure suitable for a high-salt environment and a construction process thereof. BACKGROUND

[0002] At present, in order to reduce the water seepage of buildings, waterproof structures are often designed, and the method adopted by the common waterproof structure mainly depends on single rigid or flexible waterproof materials, wherein the most common method is to use concrete self-waterproofing, apply cement-based waterproof mortar and coating, and use flexible sealing materials to process detail joints. These technologies are widely used in various underground structure engineering such as subways, tunnels and underground garages.

[0003] However, when the building is located in a high-salt environment, the waterproof structure in the high-salt environment is easily eroded by the long-term erosion of high-salt groundwater due to the chemical corrosiveness of high-salt groundwater to the waterproof structure, and thus the waterproof structure is prone to deformation, cracking or damage, thereby causing the waterproof structure to fail. Therefore, the existing waterproof structure has weak strength and short service life in the high-salt environment. SUMMARY

[0004] The application provides a rigid composite waterproof structure suitable for a high-salt environment and a construction process thereof, which aims to improve the waterproof performance of the waterproof structure in the high-salt environment, improve the service life and waterproof effect of the waterproof structure.

[0005] In a first aspect, the rigid composite waterproof structure suitable for a high-salt environment provided by the application adopts the following technical scheme:

[0006] The rigid composite waterproof structure suitable for a high-salt environment comprises a bottom plate, a plurality of side walls are arranged on the bottom plate, the side walls are vertically arranged, and an indoor space is formed between the bottom plate and the plurality of side walls; a water collecting cavity is arranged in the side wall, and a plurality of water collecting cavities are sequentially and spacedly arranged along the length direction of the side wall; an outer wall waterproof layer is arranged on the outer side wall of the side wall, an inner wall waterproof layer is arranged on the inner side wall of the side wall, and a buffer waterproof layer is arranged on the inner wall of the water collecting cavity.

[0007] By adopting the above technical scheme, the indoor space is formed under the cooperation of the bottom plate and the plurality of side walls, which meets the basic requirements of the corresponding waterproof building.

[0008] On this basis, the water collecting cavity is arranged in the side wall, the outer wall waterproof layer is arranged outside the side wall, the buffer waterproof layer is arranged on the inner wall of the water collecting cavity, and the inner wall waterproof layer is arranged in the side wall, so that three layers of waterproof barriers are sequentially stacked under the cooperation of the outer wall waterproof layer, the buffer waterproof layer and the inner wall waterproof layer.

[0009] Specifically, the first waterproof barrier: the outer wall waterproof layer can block the erosion and osmotic pressure of the high-salt underground water in the backfill layer outside the building. The second waterproof barrier: when the outer wall waterproof layer is damaged and the high-salt underground water seeps into the side wall, the buffer waterproof layer coated on the inner wall of the water collecting cavity can block the further penetration of the high-salt underground water. Even if the buffer waterproof layer is damaged, the high-salt underground water will be directly collected into the buffer waterproof layer, and if the high-salt underground water needs to continue to penetrate the side wall, the second buffer waterproof layer needs to be damaged, which can further block the penetration of the high-salt underground water. The third waterproof barrier: the inner wall waterproof layer can prevent water in the indoor space from penetrating into the side wall, and also prevent the high-salt underground water that has penetrated into the side wall from penetrating into the indoor space, which can further block the penetration of water.

[0010] Therefore, the application forms three layers of waterproof barriers in sequence under the cooperation of the outer wall waterproof layer, the buffer waterproof layer and the inner wall waterproof layer, which can effectively enhance the waterproof performance and service life of the waterproof structure, thereby improving the applicability of the waterproof structure in a high-salt environment.

[0011] Optionally, a concrete cushion layer is arranged below the bottom plate, a waterproof layer is arranged on the concrete cushion layer, the bottom plate is cast on the waterproof layer, and the outer wall waterproof layer is overlapped with the waterproof layer.

[0012] By adopting the above technical solution, the design of the waterproof layer can improve the waterproof performance of the bottom plate, and further enhance the waterproof performance of the waterproof structure. On this basis, since the outer wall waterproof layer is overlapped with the waterproof layer, a waterproof shell wrapping the building can be formed outside the building, thereby ensuring the integrity of the waterproof structure, and effectively reducing the risk of high-salt underground water seeping from between the bottom plate and the side wall.

[0013] Optionally, a plurality of drainage pipes are pre-embedded in the side wall, the drainage pipes are arranged one-to-one corresponding to the water collecting cavities, one end of the drainage pipe is communicated with the corresponding water collecting cavity, and the other end extends into the indoor space.

[0014] By adopting the above technical solution, the design of the drainage pipe provides an active drainage channel for the corresponding water collecting cavity. After the high-salt underground water seeps into and converges in the water collecting cavity, the drainage pipe can drain the high-salt underground water in the corresponding water collecting cavity, thereby reducing the further erosion of the buffer waterproof layer by the high-salt underground water in the water collecting cavity. At the same time, the high-salt underground water drained in the drainage pipe can also serve as an indication signal of the failure of the outer wall waterproof layer, which is convenient for timely determining whether the side wall is seeped and the position of the seepage.

[0015] Optionally, a sealing cover is detachably arranged at one end of the drainage pipe, the sealing cover closes the drainage pipe, and the sealing cover is located in the indoor space.

[0016] By adopting the technical scheme, the sealing cover can seal the drain pipe, so that moisture or foreign matter in the indoor space cannot enter the pipe, thereby ensuring that the drain pipe can work normally. When it is necessary to determine whether the side wall leaks, the management personnel can open the sealing cover, thereby realizing the determination of the leakage condition.

[0017] Optionally, the anti-seepage monitor and a plurality of humidity sensors are further included, the plurality of humidity sensors are electrically connected with the anti-seepage monitor, the humidity sensors are arranged in one-to-one correspondence with the drain pipes, and the detection end of the humidity sensor is located in the corresponding drain pipe.

[0018] By adopting the technical scheme, under the cooperation of the humidity sensor and the anti-seepage monitor, the humidity sensor can monitor the humidity change in the drain pipe in real time, and early warning of failure of the outer wall waterproof layer can be realized. Once leakage occurs, the corresponding humidity sensor can immediately detect humidity anomaly, and the anti-seepage monitor can issue an alarm, so that invisible underground leakage problems are converted into visual data signals, and the management personnel can timely find and accurately locate the fault area.

[0019] Optionally, the humidity sensor is arranged on the corresponding sealing cover, the drain pipe is arranged in an inclined manner in the vertical direction, the upper end of the drain pipe is in communication with the corresponding water collecting cavity, and the lower end of the drain pipe is detachably connected with the corresponding sealing cover.

[0020] By adopting the technical scheme, since the drain pipe is arranged in an inclined manner, high-salt underground water entering the drain pipe can quickly gather at the lower end of the drain pipe, so as to enter the detection area of the humidity sensor, which facilitates the humidity sensor to quickly detect the seepage condition, thereby improving the sensitivity and response speed of the seepage condition monitoring.

[0021] Optionally, the water absorption mechanism further includes a plurality of support frames, the support frames are arranged in one-to-one correspondence with the water collecting cavities, and the support frames are located in the corresponding water collecting cavities; a one-way water seepage sleeve is arranged outside the support frame, and a high-salt medium layer is filled in the support frame; and the drain pipe is in communication with the corresponding support frame.

[0022] By adopting the technical scheme, the water absorption mechanism is designed in cooperation with the support frame and the one-way water seepage sleeve. The design of the one-way water seepage sleeve makes the high-salt underground water only enter the support frame from outside the support frame, and the high-salt underground water in the support frame cannot seep back to outside the support frame, so that the support frame has a water locking function.

[0023] On this basis, through the design of the high-salt medium layer, when the high-salt underground water enters the water collecting cavity, under the action of osmotic pressure, the high-salt medium layer will suck the high-salt underground water outside the support frame into the support frame, and greatly inhibit the reverse osmosis of water, which can realize the water absorption function.

[0024] Therefore, under the cooperation of the support frame, the high-salt medium layer and the one-way water permeable sleeve, the high-salt underground water seeping into the corresponding water collecting cavity can be timely absorbed, which can reduce the residual of the high-salt underground water in the water collecting cavity, thereby further reducing the erosion of the buffer waterproof layer and improving the service life of the buffer waterproof layer.

[0025] Since the drain pipe is in communication with the support frame, the drain pipe can timely drain the high-salt underground water absorbed in the support frame, and it is also convenient to confirm whether the side wall seeps water through the drain pipe.

[0026] Optionally, the water collecting cavity is filled with a water guiding particle layer, and the water guiding particle layer is filled between the inner wall of the water collecting cavity and the outer wall corresponding to the support frame.

[0027] By adopting the above technical solution, the water guiding particle layer is filled between the inner wall of the water collecting cavity and the support frame, so that after the high-salt underground water seeps into the water collecting cavity, the high-salt underground water will flow inside the water guiding particle layer, preventing the high-salt underground water from directly gathering at the bottom of the water collecting cavity. Since the high-salt underground water flows inside the water guiding particle layer, it is easier for the high-salt underground water to contact the support frame, and under the action of the high-salt medium layer, the high-salt underground water is more easily absorbed into the support frame, which can improve the water absorption efficiency of the support frame. Therefore, the retention time of the high-salt underground water in the water collecting cavity can be reduced, thereby improving the service life of the buffer waterproof layer.

[0028] Optionally, a plurality of support steel meshes are arranged on the periphery of the support frame, each of the support steel meshes is covered with a one-way water permeable film, each of the plurality of support steel meshes is detachably connected with the support frame, and the plurality of one-way water permeable films are spliced to form the one-way water permeable sleeve.

[0029] By adopting the above technical solution, the support steel mesh provides reliable skeleton support for the one-way water permeable film, preventing it from deforming or being damaged under high water pressure, and ensuring the stability and effectiveness of its long-term work. At the same time, the detachable connection mode also provides convenience for subsequent maintenance or replacement.

[0030] In the second aspect, a construction process of a rigid composite waterproof structure suitable for a high-salt environment provided by the present application adopts the following technical solution:

[0031] The application discloses a construction process of a rigid composite waterproof structure suitable for a high-salt environment.

[0032] By adopting the technical scheme, the construction process can form the water-collecting cavity in the side wall, and the buffer waterproof layer is arranged on the inner wall of the water-collecting cavity, so that the inner wall waterproof layer, the buffer waterproof layer and the outer wall waterproof layer cooperatively form three-layer waterproof barriers which are stacked in sequence, thereby optimizing the waterproof performance of the waterproof structure.

[0033] To sum up, the application has at least one of the following beneficial technical effects:

[0034] 1. The application cooperatively forms three-layer waterproof barriers which are stacked in sequence through the outer wall waterproof layer, the buffer waterproof layer and the inner wall waterproof layer, so that the waterproof performance and the service life of the waterproof structure can be effectively improved, thereby improving the applicability of the waterproof structure in the high-salt environment.

[0035] 2. The application cooperatively designs the outer wall waterproof layer and the anti-seepage layer, so that the water seepage at the connecting position of the side wall and the bottom plate can be effectively reduced, thereby improving the waterproof performance of the waterproof structure.

[0036] 3. The application cooperatively designs the drainage pipe and the water absorption mechanism, so that the high-salt underground water seeping into the water-collecting cavity can be quickly drained, thereby reducing the influence on the buffer waterproof layer, so that the stability of the waterproof structure can be improved, and the waterproof performance and the service life of the waterproof structure can be further improved.

DETAILED DESCRIPTION

[0049] The following will be described in detail with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 11 , the present application will be further described in detail.

[0050] Embodiment 1: A rigid composite waterproof structure suitable for high-salt environment, referring to Figure 1 and Figure 2 , comprising a bottom plate 1 and a plurality of side walls 2, the plurality of side walls 2 are vertically cast on the bottom plate 1, and the indoor space 3 is formed between the bottom plate 1 and the plurality of side walls 2.

[0051] Referring to Figure 1 and Figure 2 , before the construction of the bottom plate 1, a concrete cushion layer 11 is cast on the soil layer, and an anti-seepage layer 12 is arranged on the concrete cushion layer 11, and the bottom plate 1 is cast on the anti-seepage layer 12.

[0052] Referring to Figure 1 and Figure 2 ​After pouring the side wall 2, an outer wall waterproof layer 21 is arranged outside the side wall 2, an inner wall waterproof layer 22 is arranged inside the side wall 2, and the outer wall waterproof layer 21 extends downward to overlap the anti-seepage layer 12 between the bottom plate 1 and the concrete cushion 11.

[0053] With reference to Figure 1 and Figure 2 , a plurality of water collecting cavities 23 are arranged in the side wall 2, the plurality of water collecting cavities 23 are sequentially and spacedly arranged along the length direction of the corresponding side wall 2, and a buffer waterproof layer 24 is arranged on the inner wall of each water collecting cavity 23.

[0054] With reference to Figure 1 and Figure 2 , the waterproof structure further comprises a top plate 4, the top plate 4 is located in the indoor space 3, and the plurality of side walls 2 are connected with the top plate 4, the top plate 4 is spacedly arranged above the bottom plate 1, and a top waterproof layer 41 is arranged on the upper side of the top plate 4.

[0055] With reference to Figure 1 and Figure 2 , in the embodiment, the anti-seepage layer 12 adopts a pre-paved and reversely-stuck high-molecular waterproof roll; the outer wall waterproof layer 21, the inner wall waterproof layer 22 and the top waterproof layer 41 all adopt a polymer-modified cement waterproof mortar; and the buffer waterproof layer 24 adopts a cement-based permeable crystalline waterproof material.

[0056] The main components of the polymer-modified cement waterproof mortar are: taking cement and quartz sand as the basic framework, and introducing a high-molecular polymer (such as an acrylate emulsion) as a modifier. The mechanism of the waterproof effect is the synergistic effect between the rigid inorganic framework formed by the hydration of cement and the flexible waterproof film formed by the cross-linking solidification of the high-molecular polymer. The synergistic effect is reflected in that the cement provides high strength and basic impermeability, while the high-molecular polymer fills and blocks the capillary pores in the cement hardened body at the micro level, and at the same time, the polymer-modified cement waterproof mortar after solidification has excellent flexibility and adhesion, effectively resisting the micro deformation and cracking of the cement.

[0057] Based on the characteristics of the polymer-modified cement waterproof mortar, the outer wall waterproof layer 21 and the inner wall waterproof layer 22 can form a firm and wear-resistant surface protection, effectively resist external environmental erosion and provide an internal final barrier.

[0058] The main components of the cement-based capillary crystalline waterproofing material are: special cement (such as high-salt underground cement) and quartz sand as the carrier platform, and the introduction of various special active chemicals (such as alkali metal silicate, complex, etc.). The waterproof effect mechanism is: the active chemicals are carried by water, penetrate into the concrete, and catalyze the chemical reaction of free calcium ions in the concrete to generate water-insoluble crystals. The function brought by the mechanism is: the crystals fill, block and seal the capillary channels and microcracks of the concrete at the micro level, so that the concrete structure itself is transformed into a dense and permanent waterproof body. More importantly, the reaction has self-repairing properties. When new microcracks occur in the structure later, the latent active chemicals can be activated again when they come into contact with water, generating new crystals to seal the cracks and achieve secondary impermeability.

[0059] Based on the characteristics of the cement-based capillary crystalline waterproofing material, the buffer waterproof layer 24 can self-repair, thereby further improving the reliability of the waterproof structure.

[0060] Referring to Figure 1 and Figure 2 , in cooperation with the waterproof layer 21 and the waterproof layer 12, the building exterior is closed, so that the high-salt underground water in the backfill layer 200 can be effectively prevented from seeping between the side wall 2 and the bottom plate 1, thereby effectively improving the waterproof performance. Based on the design of the buffer waterproof layer 24, a buffer layer can be formed between the inner wall waterproof layer 22 and the outer wall waterproof layer 21. When the high-salt underground water on the outside of the building corrodes and damages the outer wall waterproof layer 21, the design of the buffer waterproof layer 24 can block the further corrosion of the high-salt underground water to the side wall 2, thereby ensuring the service life of the side wall 2. When the outer wall waterproof layer 21 and the buffer waterproof layer 24 are both ineffective, the inner wall waterproof layer 22 can effectively block the penetration of the high-salt underground water, thereby providing a final safety barrier for the indoor space 3 and ensuring the long-term dryness and structural safety of the basement interior.

[0061] Referring to Figure 2 , in this embodiment, the connection between the side wall 2 and the bottom plate 1 and the connection between the side wall 2 and the top plate 4 are both provided with a node reinforced waterproof layer 100, and the node reinforced waterproof layer 100 is made of cement-based capillary crystalline waterproofing material. In addition, the expansion joints and connecting joints on the side wall 2, the bottom plate 1 and the top plate 4 are all provided with a node reinforced waterproof layer.

[0062] Therefore, based on the characteristics of the cement-based capillary crystalline waterproofing material, the node reinforced waterproof layer 100 can convert the construction joint with structural weakness into a dynamic waterproof area with self-healing ability and integrity by its unique mechanism of capillary crystallization and self-repairing. It does not adapt to deformation by the physical elasticity of the material, but realizes the dynamic waterproof effect by the active repair ability of chemical reaction, so as to greatly improve the long-term reliability and durability of the key node.

[0063] The implementation principle of the embodiment of the present application is that, by cooperation of the outer wall waterproof layer 21 and the anti-seepage layer 12, the buffer waterproof layer 24 and the inner wall waterproof layer 22, the following three waterproof barriers are formed from outside to inside:

[0064] The first waterproof barrier: the outer wall waterproof layer 21 and the anti-seepage layer 12 construct a physical isolation layer on the outside of the building, which is mainly used to block the erosion and osmotic pressure of the high-salt underground water in the backfill soil layer on the outside of the building.

[0065] The second waterproof barrier: under the design of the water collecting cavity 23, when the outer wall waterproof layer 21 is damaged and the high-salt underground water seeps into the side wall 2, the buffer waterproof layer 24 coated on the inner wall of the water collecting cavity 23 can block the further penetration of the high-salt underground water. Even if the buffer waterproof layer 24 is damaged, the high-salt underground water will be directly collected into the buffer waterproof layer 24, and if the high-salt underground water needs to continue to penetrate the side wall 2, the second buffer waterproof layer 24 needs to be damaged, which can further block the penetration of the high-salt underground water.

[0066] The third waterproof barrier: the inner wall waterproof layer 22 can prevent the water in the indoor space 3 from penetrating into the side wall 2, and also can prevent the high-salt underground water penetrating into the side wall 2 from penetrating into the indoor space 3, which can further block the penetration of water.

[0067] The embodiment also discloses a construction process of a rigid composite waterproof structure suitable for a high-salt environment, which comprises the following steps:

[0068] Foundation pit excavation and cushion construction: the foundation pit is excavated at a preset position, and the foundation pit is checked, and then the concrete cushion 11 is constructed.

[0069] Bottom plate 1 construction: the anti-seepage layer 12 is laid on the concrete cushion 11, and the anti-seepage layer 12 is ensured to extend to all around according to the construction requirement; after the anti-seepage layer 12 is laid, the bottom plate 1 steel bars are bound, and the bottom plate 1 is poured.

[0070] Side wall 2 construction: the side wall 2 steel bars are bound on the bottom plate 1, the outer mold is arranged outside the side wall 2 steel bars, and finally the side wall 2 is poured, and the water collecting cavity 23 is formed in the side wall 2.

[0071] Specifically, when binding the side wall 2 steel bars, the inner mold is fixed in the side wall 2 steel bars, so that the design of the inner mold is used to ensure that the water collecting cavity 23 is formed in the side wall 2 after pouring.

[0072] The first waterproof layer construction: when the side wall 2 reaches the design strength, the inner mold and the outer mold are removed, and the buffer waterproof layer 24 is arranged on the inner wall of the water collecting cavity 23.

[0073] The roof 4 construction: the roof 4 formwork is erected, the roof 4 steel bars are bound, and the roof 4 is poured.

[0074] The second waterproof layer construction: the node reinforcing waterproof layer is arranged at the connection between the bottom plate 1, the roof 4 and the side wall 2, and then the inner wall waterproof layer 22, the outer wall waterproof layer 21 and the top waterproof layer 41 are constructed.

[0075] The implementation principle of the embodiment of the application is that the water collecting cavity 23 is formed inside the side wall 2, and the buffer waterproof layer 24 is arranged on the inner wall of the water collecting cavity 23, so that the inner wall waterproof layer 22, the buffer waterproof layer 24 and the outer wall waterproof layer 21 cooperate to form three layers of waterproof barriers which are stacked in sequence, thereby optimizing the waterproof performance of the waterproof structure.

[0076] Embodiment 2: A rigid composite waterproof structure suitable for a high-salt environment, referring to Figure 1 and Figure 3 The difference between the embodiment and the embodiment 1 is that the side wall 2 comprises an outer wall 25, an inner wall 26 and a connecting wall 27, the inner wall 26 and the outer wall 25 are both vertically arranged on the bottom plate 1, the inner wall 26 and the outer wall 25 are parallel and spaced apart, and the outer wall 25 is located on the side of the inner wall 26 facing the backfill soil layer 200. The connecting wall 27 is located between the inner wall 26 and the outer wall 25, and the connecting wall 27 is arranged on the bottom plate 1, the bottom of the outer wall 25 and the bottom of the inner wall 26 are all connected with the connecting wall 27.

[0077] Referring to Figure 3 and Figure 4 The side wall 2 further comprises a plurality of reinforcing walls 28. The reinforcing walls 28 are vertically arranged, the lower ends of the reinforcing walls 28 are connected with the connecting wall 27, the opposite sides of the reinforcing walls 28 are respectively connected with the outer wall 25 and the inner wall 26, and the plurality of reinforcing walls 28 are sequentially and spaced apart along the length direction of the outer wall 25.

[0078] Referring to Figure 3 and Figure 4 A corresponding water collecting cavity 23 is formed between the adjacent two reinforcing walls 28, the outer wall 25, the inner wall 26 and the connecting wall 27.

[0079] Referring to Figure 3 and Figure 4, based on the structural design of the side wall 2, under the action of the connecting wall 27 and the reinforcing wall 28, the outer wall 25, the inner wall 26, the connecting wall 27 and the reinforcing wall 28 can be integrally poured, which can improve the integrity of the side wall 2 structure, thereby optimizing the bearing capacity of the side wall 2, and also making the definition of the water collecting cavity 23 more clear and standardized.

[0080] With reference to Figure 3 , the side wall 2 further comprises an upper sealing wall 29, the upper sealing wall 29 is arranged at the top of the inner wall 26, and the upper sealing wall 29 seals the top of the corresponding water collecting cavity 23 in the side wall 2.

[0081] In this embodiment, with reference to Figure 3 and Figure 4 , the upper sealing wall 29 is crimped on the inner wall 26, one side of the upper sealing wall 29 is connected with the inner side wall of the outer wall 25, and the other side is flush with the inner side wall of the inner wall 26, and the upper end of the reinforcing wall 28 and the upper end of the inner wall 26 are connected with the upper sealing wall 29. The roof 4 is arranged on the upper side of the upper sealing wall 29, the roof 4 is crimped on the upper sealing wall 29, and the roof 4 is connected with the inner side wall of the corresponding outer wall 25.

[0082] The upper sealing wall 29 can seal the water collecting cavity 23, thereby preventing sundries, surface water and the like from falling into the water collecting cavity 23 during subsequent construction or use, thereby ensuring the influence of the construction process of the building roof 4 and the like on the buffer waterproof layer 24 on the inner wall of the water collecting cavity 23. Secondly, the upper sealing wall 29 serves as a transverse tie beam at the top, firmly connecting the upper ends of the outer wall 25, the inner wall 26 and the reinforcing wall 28 together, thereby further improving the stability of the side wall 2 structure. In addition, the position design of the upper sealing wall 29 and the roof 4 together constructs an efficient load transfer path, so that the vertical load borne by the roof 4 is uniformly distributed to the side wall 2, fully utilizes the cooperative bearing capacity of the side wall 2, avoids stress concentration, and improves the safety of the overall structure. Moreover, the outer wall 25 directly seals the joint between the roof 4 and the upper sealing wall 29, thereby further improving the waterproof performance of the waterproof structure.

[0083] With reference to Figure 3 , in this embodiment, the outer wall 25 is provided with an outer wall waterproof layer 21 on the outside, the inner wall 26 is provided with an inner wall waterproof layer 22 on the inside, and the roof 4 is provided with a top waterproof layer 41 on the upper side, under the cooperation of the outer wall waterproof layer 21, the top waterproof layer 41, the inner wall waterproof layer 22 and the impermeable layer 12, each direction of the indoor space 3 can be covered, thereby preventing high-salt underground water from seeping into the indoor space 3.

[0084] With reference to Figure 3 and Figure 4In the embodiment, the inner side wall of the outer wall 25, the upper side wall of the connecting wall 27, the outer side wall of the inner wall 26, and the opposite side walls of the reinforcing wall 28 are all provided with the buffer waterproof layer 24, so that the inner wall of the water collecting cavity 23 and the bottom inner wall are all covered with the buffer waterproof layer 24.

[0085] Based on the design of the buffer waterproof layer 24, the water collecting cavity 23 forms a water collecting liner, so that the water collecting cavity 23 can collect the high-salt underground water that seeps into the side wall 2, and further prevent the high-salt underground water that seeps into the water collecting cavity 23 from further penetrating into the inner wall 26 under the action of the buffer waterproof layer 24.

[0086] Referring to Figure 3 and Figure 5 , a plurality of drainage pipes 5 are pre-buried in the inner wall 26, the length direction of the drainage pipe 5 is arranged along the thickness direction of the inner wall 26, and the drainage pipe 5 penetrates through the inner wall 26 along the length direction of the drainage pipe 5. The drainage pipe 5 is arranged in one-to-one correspondence with the water collecting cavity 23, one end of the drainage pipe 5 is in communication with the corresponding water collecting cavity 23, and the other end extends to the indoor space 3.

[0087] Under the action of the drainage pipe 5, the drainage pipe 5 is in communication with the corresponding water collecting cavity 23, so that the drainage pipe 5 can actively discharge the high-salt underground water collected in the corresponding water collecting cavity 23. On the one hand, the discharged high-salt underground water can serve as an indication signal of water seepage of the outer wall 25; on the other hand, discharging the high-salt underground water can reduce the further penetration of the high-salt underground water into the inner wall 26, thereby prolonging the service life of the inner wall 26 and ensuring the stability of the waterproof structure.

[0088] Referring to Figure 3 and Figure 4 , in the embodiment, the drainage pipe 5 is in communication with the bottom of the corresponding water collecting cavity 23. This can reduce the internal water accumulation of the water collecting cavity 23 and avoid the problems of long-term soaking and water quality deterioration caused by water accumulation.

[0089] Referring to Figure 3 and Figure 5 , one end of the drainage pipe 5 is provided with a sealing cover 51, the sealing cover 51 seals the drainage pipe 5, the sealing cover 51 is detachably connected with the drainage pipe 5, and the sealing cover 51 is located in the indoor space 3. In the embodiment, the sealing cover 51 is screwed with the drainage pipe 5.

[0090] In daily use, the sealing cover 51 can prevent indoor moisture, dust or foreign matter from entering the drainage pipe 5. While in daily inspection, the sealing cover 51 can be detached, thereby facilitating water seepage inspection and drainage pipe 5 dredging.

[0091] The implementation principle of the embodiment of the present application is that when the outer wall waterproof layer 21 on the outer layer wall 25 is damaged and high-salt underground water seeps into the outer layer wall 25, the high-salt underground water continues to seep into the outer layer wall 25, at this time, the buffer waterproof layer 24 on the inner wall of the water collecting cavity 23 has a secondary waterproof function, thereby being able to block the further penetration of the high-salt underground water.

[0092] After that, when the buffer waterproof layer 24 is damaged and the high-salt underground water seeps out of the outer layer wall 25 and gathers in the water collecting cavity 23, since the inner wall of the water collecting cavity 23 and the bottom inner wall are covered with the buffer waterproof layer 24, this can gather the high-salt underground water seeping into the water collecting cavity 23 and prevent the further penetration of the high-salt underground water. At this time, in the process of daily inspection, the water in the water collecting cavity 23 is discharged through the corresponding drain pipe 5, which can prevent the high-salt underground water from continuing to penetrate into the inner layer wall 26 and can facilitate timely determination of whether the outer layer wall 25 is seeping water.

[0093] Since the water collecting cavity 23 is provided with a plurality of water collecting cavities 23 arranged in sequence, when the corresponding drain pipe 5 discharges the high-salt underground water in one water collecting cavity 23, it can be determined that the outer layer wall 25 at the position of the corresponding water collecting cavity 23 is seeping water, so it can timely determine the seepage position and facilitate repair of the seepage position.

[0094] Embodiment 3: A rigid composite waterproof structure suitable for a high-salt environment, referring to Figure 6 and Figure 7 The difference between the present embodiment and embodiment 2 is that it further comprises a plurality of water absorbing mechanisms 6, the water absorbing mechanisms 6 are one-to-one corresponding to the water collecting cavities 23, and the water absorbing mechanisms 6 are located in the corresponding water collecting cavities 23.

[0095] Referring to Figure 6 and Figure 7 The water absorbing mechanism 6 comprises a support frame 61, the support frame 61 is one-to-one corresponding to the water collecting cavities 23, and the support frame 61 is vertically arranged in the corresponding water collecting cavity 23, and a one-way water seepage sleeve 62 is sleeved outside the support frame 61.

[0096] The water absorbing mechanism 6 is designed by the cooperation of the support frame 61 and the one-way water seepage sleeve 62, so that the high-salt underground water seeping into the corresponding water collecting cavity 23 can pass through the one-way water seepage sleeve 62 and enter the support frame 61, which can reduce the retention of the high-salt underground water in the water collecting cavity 23 and further reduce the erosion of the high-salt underground water to the inner wall of the water collecting cavity 23.

[0097] Referring to Figure 7 and Figure 8The support frame 61 is provided with a support steel mesh 611 on each side, and the support steel mesh 611 is detachably connected with the support frame 61. The one-way water permeable sleeve 62 comprises a plurality of one-way water permeable membranes 621, the support steel mesh 611 and the one-way water permeable membrane 621 are arranged one by one, and the one-way water permeable membrane 621 covers the corresponding support steel mesh 611, and the one-way water permeable membrane 621 seals the corresponding support steel mesh 611.

[0098] Based on the cooperation design of the plurality of support steel meshes 611, since the support steel mesh 611 can support the one-way water permeable membrane 621, the plurality of one-way water permeable membranes 621 can be spliced into the one-way water permeable sleeve 62, and the plurality of support steel meshes 611 form the framework supporting the one-way water permeable sleeve 62, effectively preventing the one-way water permeable sleeve 62 from deforming or being damaged under high water pressure or external extrusion, and ensuring the long-term effective working mode and the filtration / penetration area.

[0099] Referring to Figure 8 The one-way water permeable membrane 621 comprises a filtration membrane layer, a semi-permeable membrane layer and a reinforcing mesh layer which are stacked in sequence, and the filtration membrane layer is located on the side of the semi-permeable membrane layer away from the support frame 61, and the reinforcing mesh layer is located on the side of the semi-permeable membrane layer facing the support frame 61. The filtration membrane layer adopts non-woven geotextile or polyester fiber felt, the semi-permeable membrane layer adopts composite polyamide reverse osmosis membrane or cellulose acetate membrane, and the reinforcing mesh layer adopts stainless steel mesh or high-strength glass fiber mesh.

[0100] Based on the structural design of the one-way water permeable membrane 621, first, the filtration membrane layer is used to intercept particulate impurities in water to prevent the particulate impurities from affecting the semi-permeable membrane layer. Then, the semi-permeable membrane layer can realize one-way water permeation, ensuring that water can pass through the semi-permeable membrane into the corresponding support frame 61, and preventing water in the support frame 61 from passing through the semi-permeable membrane in the opposite direction; finally, the reinforcing mesh layer is used to provide structural support for the one-way water permeable membrane 621, ensuring the stability of the one-way water permeable membrane 621.

[0101] Referring to Figure 6 and Figure 8 The support frame 61 is filled with a high-salt medium layer 63.

[0102] Specifically, the high-salt medium layer 63 is preferably high-purity industrial salt. When the high-purity industrial salt is placed in the support frame 61, under the action of osmotic pressure, water in the water collection cavity 23 will be absorbed into the support frame 61 after the high-salt groundwater seeps into the water collection cavity 23, and the reverse osmosis of water is greatly inhibited, thereby realizing efficient water collection and water control functions.

[0103] Referring to Figure 8 and Figure 9The bottom of the support frame 61 is provided with a connecting pipe 612, which is embedded on the corresponding support steel mesh 611 and communicates with the support frame 61 at one end and extends downward and inward to the inner layer wall 26 at the other end.

[0104] With reference to Figure 9 The connecting pipe 612 is arranged one-to-one with the drain pipe 5, and the drain pipe 5 is coaxially and detachably connected to the end of the corresponding connecting pipe 612 facing the inner layer wall 26. In this embodiment, the drain pipe 5 is screwed with the corresponding connecting pipe 612.

[0105] Based on the design of the connecting pipe 612, the drain pipe 5 communicates with the support frame 61, which facilitates the drainage of high-salt groundwater in the support frame 61. On this basis, since the drain pipe 5 is detachably connected to the connecting pipe 612, the assembly of the drain pipe 5 and the support frame 61 is facilitated, thereby reducing the complexity of on-site construction.

[0106] With reference to Figure 6 and Figure 9 The inner layer wall 26 is pre-buried with a plurality of through pipes 64, which communicate with the water collecting cavity 23, and one end of the through pipe 64 communicates with the corresponding water collecting cavity 23, and the other end communicates with the indoor space 3. The drain pipe 5 is arranged one-to-one with the through pipe 64, and the drain pipe 5 is coaxially inserted and matched with the corresponding through pipe 64, and the drain pipe 5 is slidingly connected with the inner wall of the corresponding through pipe 64.

[0107] The through pipe 64 is pre-buried on the inner layer wall 26, which facilitates the insertion of the drain pipe 5 into the water collecting cavity 23, and facilitates the connection of the drain pipe 5 with the corresponding connecting pipe 612. After the drain pipe 5 is stably installed with the corresponding connecting pipe 612, sealant or a sealing ring is applied between the drain pipe 5 and the corresponding through pipe 64, which can ensure the sealing of the inner layer wall 26.

[0108] With reference to Figure 6 and Figure 9 The water collecting cavity 23 is filled with a water guiding particle layer 65, and the support frame 61 is located in the water guiding particle layer 65, and the water guiding particle layer 65 is filled between the inner side wall of the corresponding water collecting cavity 23 and the one-way water permeable film 621 on the corresponding support frame 61. The water guiding particle layer 65 is made of gravel or ceramic particles.

[0109] On the one hand, since there are a large number of inter-connected voids between the granular materials, water channels can be formed in the water guide granular layer 65, so when the high-salt underground water seeps into the inner wall of the water accumulation cavity 23, the seeped high-salt underground water will flow along the water channels to the support frame 61 and enter the support frame 61 under the action of osmotic pressure, which can prevent the high-salt underground water from accumulating between the inner wall of the water accumulation cavity 23 and the outer wall of the support frame 61, thereby reducing the erosion of the buffer waterproof layer 24. On the other hand, the water guide granular layer 65 can completely wrap and fix the support frame 61 in the center of the water accumulation cavity 23, providing uniform lateral support for the support frame 61 and effectively preventing it from shifting or toppling during installation or long-term use.

[0110] The implementation principle of the embodiment of the present application is that the support frame 61 is additionally arranged in the water accumulation cavity 23, and when the high-salt underground water seeps into the water accumulation cavity 23, the water channels in the water guide granular layer 65 will quickly guide the high-salt underground water into the support frame 61. At this time, due to the presence of the high-salt medium layer 63 in the support frame 61, water outside the support frame 61 will be quickly absorbed into the support frame 61 based on the osmotic pressure principle. Under the action of the one-way water seepage film 621, the high-salt underground water is enclosed in the support frame 61, and the high-salt underground water sinks to the bottom of the support frame 61 under the action of its own gravity. During daily inspection, the water in the support frame 61 will be discharged from the drain pipe 5 after the drain pipe 5 is opened.

[0111] Under the action of the support frame 61, the water seeping into the water accumulation cavity 23 will be absorbed into the support frame 61, thereby reducing the erosion of the buffer waterproof layer 24 on the inner wall of the water accumulation cavity 23 by the high-salt underground water and improving the service life of the waterproof structure.

[0112] Embodiment 4: A rigid composite waterproof structure suitable for a high-salt environment, referring to Figure 10 With Figure 11 The difference between the present embodiment and embodiment 3 is that the present embodiment further comprises an anti-seepage intelligent monitoring mechanism 7, the anti-seepage intelligent monitoring mechanism 7 comprises an anti-seepage monitor 71, a plurality of humidity sensors 72 and a plurality of salinity sensors 73, and the plurality of humidity sensors 72 and the plurality of salinity sensors 73 are electrically connected to the anti-seepage monitor 71. The humidity sensors 72 are one-to-one correspondingly arranged with the sealing covers 51, the salinity sensors 73 are one-to-one correspondingly arranged with the sealing covers 51, the humidity sensors 72 and the salinity sensors 73 are arranged on the corresponding sealing covers 51, and the detection ends of the humidity sensors 72 and the detection ends of the salinity sensors 73 extend into the corresponding drain pipes 5.

[0113] The anti-seepage intelligent monitoring mechanism 7 is designed in cooperation with the humidity sensor 72, the salinity sensor 73 and the anti-seepage monitor 71. The humidity sensor 72 detects the humidity in the drain pipe 5, so as to determine whether there is water in the support frame 61, and thus determine whether the side wall 2 leaks. The salinity sensor 73 can detect the salt content in the water in the drain pipe 5, so as to determine whether the high-salt medium layer 63 is invalid. When the high-salt medium layer 63 is valid, the salt content in the water is stable at a maximum value, and when the high-salt medium layer 63 is invalid, the salt content in the water will be significantly reduced. The anti-seepage monitor 71 uses PLC as a controller, and uses a buzzer or an audible and light alarm or a display screen for real-time feedback of the detection results.

[0114] With reference to Figure 9 and Figure 10 The drain pipe 5 is arranged in a vertical direction and is inclined. The upper end of the drain pipe 5 is coaxially connected with the corresponding connecting pipe 612, and the lower end of the drain pipe 5 is detachably connected with the corresponding sealing cover 51.

[0115] The drain pipe 5 is designed to be inclined, so that the water in the support frame 61 is gathered to the lower end of the drain pipe 5. Such a design, on the one hand, facilitates the water to be gathered to the detection area of the humidity sensor 72 and the salinity sensor 73, so as to improve the sensitivity and response speed of the anti-seepage intelligent monitoring mechanism 7, and ensure that early and small leakage can also be detected. On the other hand, it is convenient for the water in the support frame 61 to be drained and drained.

[0116] The implementation principle of the embodiment of the present application is that the anti-seepage intelligent monitoring mechanism 7 can detect whether there is water in the drain pipe 5 through the humidity sensor 72, so as to monitor whether the outer wall 25 leaks. With the cooperation of a plurality of humidity sensors 72, the entire side wall 2 can be monitored in real time, so as to facilitate the timely discovery of the leakage position of the side wall 2.

The same parts are indicated by the same reference numerals. Therefore, equivalent changes made according to the structure, shape and principle of the present application should be covered by the protection scope of the present application.
