Description

Technical Field

[0001] This invention relates to the field of basement waterproofing technology, and more specifically to a basement exterior wall waterproofing system and method. Background Technology

[0002] Currently, many basement waterproofing solutions are relatively traditional, focusing mainly on solving waterproofing problems, which has many drawbacks: (1) The construction process is cumbersome and the waterproofing effect is generally poor. The maintenance process requires a lot of manpower and resources, resulting in high maintenance costs; (2) There is a lack of drainage system, making it impossible to optimize the drainage system to solve the waterproofing problem; (3) There is a lack of intelligent monitoring system, making it impossible to understand the water level changes, water quality and seepage areas in real time and to make data analysis; (4) It is impossible to observe the seepage points in time and implement effective measures for repair. At the same time, the existing waterproofing system focuses on the laying of waterproof membrane during the construction process, neglecting some corners and edges that are prone to seepage. If the seepage points cannot be detected in time, water will accumulate in the corners of the basement all year round, the walls will become damp, and the strength will be reduced.

[0003] Therefore, proposing a waterproofing system and method for basement exterior walls to solve the problem of drainage from the inside to the outside, improve the accuracy and timeliness of monitoring, and avoid serious water blockage are problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the present invention provides a basement exterior wall waterproofing system and method, achieving efficient waterproofing on the basis of effective waterproofing measures, thereby improving the functionality and structural durability of underground engineering projects. Environmentally friendly, high-performance waterproofing materials are used during construction to reduce environmental pollution. Electro-osmotic waterproofing technology is employed to minimize the problem of drainage from the inside to the outside. Furthermore, internet cloud transmission improves the accuracy and immediacy of monitoring, preventing serious water blockage problems. To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A basement exterior wall waterproofing system includes: a basement waterproofing structure, an electro-osmotic waterproofing system, a basement waterproofing and damp-proofing monitoring system, and a drainage system. The electro-osmotic waterproofing system, the basement waterproofing and damp-proofing monitoring system, and the drainage system all interact with the basement waterproofing structure. The electro-osmotic waterproofing system utilizes an electric field generated by low-voltage and low-current pulse charges to cause water molecules and hydrated ions in the basement waterproofing structure to move from the positive electrode to the negative electrode, thereby expelling moisture. The drainage system collects and processes the expelled moisture. The basement waterproofing and damp-proofing monitoring system acquires and analyzes real-time data through sensors, shares data with the electro-osmotic waterproofing system via Internet of Things (IoT) technology, and controls the operation of the electro-osmotic waterproofing system.

[0006] Optionally, the electro-osmotic waterproofing system applies low voltage and low current pulse charges through the central control box, forming an electric field between the positive and negative electrodes. This causes the hydrated ions and water molecules in the diffusion layer to detach from the negative electric field on the surface of the soil particles in the pore structure. The hydrated ions and water molecules then move along the direction of the electric field force along the pore structure towards the negative electrode, thus expelling the water.

[0007] Optionally, the basement waterproofing and damp-proofing monitoring system includes: sensors and a basement management server. The sensors collect real-time data and communicate with the basement management server through Internet of Things (IoT) technology.

[0009] Optionally, the drainage system includes: an edge drainage water supply system, an internal buried pipe drainage system, and a groundwater system, which are connected in sequence.

[0010] Optionally, the basement waterproofing structure includes the bottom of the pit, the edge of the pit, and the outer wall of the basement. The pit is formed by the bottom of the pit, the edge of the pit, and the outer wall of the basement.

[0012] Optionally, a method for waterproofing the exterior walls of a basement includes:

[0013] Real-time data on the waterproofing structure of the basement is collected through a basement waterproofing and damp-proofing monitoring system.

[0014] Through the interconnection of data between the basement management server and the Internet of Things (IoT) technology, the basement management server uses big data technology to analyze and summarize data, and predict and analyze the water seepage situation in the basement.

[0015] The basement management server shares data with the electro-osmotic waterproofing system via IoT technology, controlling the operation of both the electro-osmotic waterproofing and drainage systems.

[0016] Optionally, the basement waterproofing structure includes the bottom of the pit, the edge of the pit, and the outer wall of the basement. The pit is formed by the bottom of the pit, the edge of the pit, and the outer wall of the basement. An electro-osmotic waterproofing system is installed on the edge of the pit and the outer wall of the basement. A drainage system and a basement waterproofing and damp-proofing monitoring system are installed at the bottom of the pit.

[0017] Optionally, the electro-osmotic waterproofing system, after applying low voltage and low current pulse charges through the central control box, forms an electric field between the positive and negative electrodes, causing the hydrated ions and water molecules in the diffusion layer to detach from the negative electric field on the surface of the soil particles in the pore structure, and causing the hydrated ions and water molecules to move along the direction of the electric field force along the pore structure towards the negative electrode, thereby expelling the water.

[0021] This invention proposes a basement exterior wall waterproofing system, comprising: a basement waterproofing structure, an electro-osmotic waterproofing system, a basement waterproofing and damp-proofing monitoring system, and a drainage system. The electro-osmotic waterproofing system, the basement waterproofing and damp-proofing monitoring system, and the drainage system all interact with the basement waterproofing structure. The electro-osmotic waterproofing system utilizes an electric field generated by low-voltage and low-current pulse charges to cause water molecules and hydrated ions in the basement waterproofing structure to move from the positive electrode to the negative electrode, thereby expelling moisture. The drainage system collects and processes the expelled moisture. The basement waterproofing and damp-proofing monitoring system acquires and analyzes data in real time through sensors, shares data with the electro-osmotic waterproofing system via Internet of Things (IoT) technology, and controls the operation of the electro-osmotic waterproofing system.

They contain no organic solvents or have low volatile organic compound content, thus preventing air pollution. The structure is simple and allows for rapid construction. The system has a fast response time and supports low power consumption. Unlike existing methods that rely on backfilling the space between the foundation pit boundary and the basement walls, this invention uses electro-osmotic waterproofing technology to significantly reduce the seepage of moisture from the backfill soil into the basement walls through capillary action. Low pressure forces water molecules to move in a specific direction, effectively waterproofing and preventing moisture in the basement. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention discloses a basement exterior wall waterproofing system, comprising: a basement waterproofing structure, an electro-osmotic waterproofing system, a basement waterproofing and damp-proofing monitoring system, and a drainage system. The electro-osmotic waterproofing system, the basement waterproofing and damp-proofing monitoring system, and the drainage system all interact with the basement waterproofing structure. The electro-osmotic waterproofing system utilizes an electric field generated by low-voltage and low-current pulse charges to cause water molecules and hydrated ions in the basement waterproofing structure to move from the positive electrode to the negative electrode, thereby expelling moisture. The drainage system collects and processes the expelled moisture. The basement waterproofing and damp-proofing monitoring system acquires and analyzes data in real time through sensors, shares data with the electro-osmotic waterproofing system via Internet of Things (IoT) technology, and controls the operation of the electro-osmotic waterproofing system.

[0030] Furthermore, the electro-osmotic waterproofing system applies low voltage and low current pulse charges through the central control box, creating an electric field between the positive and negative electrodes. This causes the hydrated ions and water molecules in the diffusion layer to detach from the negative electric field on the surface of the soil particles in the pore structure. The hydrated ions and water molecules then move along the direction of the electric field force along the pore structure towards the negative electrode, thus expelling the water.

[0031] Water is a polar molecule. In the microporous structure of concrete, the adsorbed ions close to the solid surface are in close contact with the solid, while the diffused ions, at a certain distance from the surface, are free in the gas / liquid, forming a double-layered positive electric field. After applying low-voltage and low-current pulse charges through the central control box, an electric field is formed between the positive and negative electrodes. This causes the hydrated ions and water molecules in the diffused layer to detach from the negative electric field on the surface of the soil particles in the pore structure. This allows the ions in the diffused layer to escape the electrostatic attraction field of the soil particle surface, causing the hydrated ions and water molecules to move along the direction of the electric field force along the pore structure towards the negative electrode, thereby achieving the effect of electroosmotic dehumidification.

[0032] During the process of hydrated cations moving from the anode to the cathode, water molecules carried by the hydrated cations are propelled towards the negative electrode by friction. At the cathode, they gain electrons and release water molecules. This process removes bound and free water from the soil through electroosmosis. When the electroosmotic moisture-proof system continuously applies current, creating an electric field, water molecules continuously move from the anode to the cathode, achieving a fundamental drainage effect.

[0033] Furthermore, the basement waterproofing and damp-proofing monitoring system includes: sensors and a basement management server. The sensors collect real-time data and communicate with the basement management server through Internet of Things (IoT) technology. The basement management server uses big data technology to analyze and summarize the data, and predict and analyze the water seepage situation in the basement.

[0034] Furthermore, the sensor includes a soil moisture sensor, a water pressure sensor, and a groundwater level sensor. The soil moisture sensor monitors the water content and outputs different analog or digital signals based on changes in resistance. The water pressure sensor monitors changes in water pressure and outputs different voltage or current signals based on the magnitude of the water pressure. The groundwater level sensor monitors the height of the groundwater level and outputs different resistance or frequency signals based on the level of the water.

[0035] A water pressure sensor can sense the measured information and transform it into an electrical signal or other required form of information output according to a certain rule, in order to meet the requirements of information transmission, processing, storage, display, recording, and control. The working principle is as follows: the water pressure sensor core is usually made of diffused silicon. The pressure of the water being measured acts directly on the diaphragm of the sensor, causing the diaphragm to produce a micro-displacement proportional to the water pressure. This causes a change in the sensor's resistance value. Electronic circuitry detects this change and converts it into a standard measurement signal corresponding to the pressure.

[0036] Soil moisture sensors employ the FDR (Frequency Domain Reflectometry) principle. They utilize the electromagnetic pulse principle and measure the apparent dielectric constant of the soil based on the propagation frequency of electromagnetic waves in a medium, thereby obtaining the relative soil moisture content. Types include capacitive, resistive, and ion-based soil moisture sensors.

[0037] Water level sensor: The LC-SW1 water level sensor consists of a fully sealed, oil-filled diaphragm sensor and a built-in high-performance microprocessor. It can digitally correct for nonlinearity and temperature drift across the entire sensor range, and features HART communication protocol output and analog output. The water level sensor transmits the sensed water level signal to the controller. The computer within the controller compares the measured water level signal with the set signal, calculates the deviation, and then, based on the nature of the deviation, issues "open" or "close" commands to the water supply electric valve to ensure the container reaches the set water level.

[0038] Furthermore, the drainage system includes: an edge drainage water supply system, an internal buried pipe drainage system, and a groundwater system. The edge drainage water supply system, the internal buried pipe drainage system, and the groundwater system are connected in sequence. The internal buried pipe drainage system performs drainage by burying pipes inside the waterproof structure of the basement. The edge drainage water supply system buries and discharges water at the edge of the waterproof structure of the basement. The groundwater system connects to the edge drainage water supply system outside the waterproof structure of the basement through buried pipes to draw water in and drain water, and discharges the accumulated water in the edge drainage water supply system into the groundwater system.

[0039] Furthermore, the basement waterproof structure includes the bottom of the pit, the edge of the pit 7, and the outer wall of the basement 4. The pit is formed by the bottom of the pit, the edge of the pit 7, and the outer wall of the basement 4. An electro-osmotic waterproofing system is installed on the edge of the pit 7 and the outer wall of the basement 4. A drainage system and a basement waterproofing and damp-proofing monitoring system are installed at the bottom of the pit.

[0040] Furthermore, it also includes the use of water-based epoxy resin moisture-proof membrane for waterproof membrane construction; the use of polymer cement elastic waterproof coating or penetrating crystalline waterproof coating for waterproof coating construction; the addition of two-component water-based epoxy resin to concrete for foundation pit filling; and the mixing of ink with water-sensitive color-changing properties into wall paint for painting the interior wall 11 of the basement exterior.

[0041] Waterproof coatings: Acrylic waterproof coatings are single-component water-emulsion type waterproof coatings made from pure acrylic polymer emulsion as the base material and with the addition of other additives. After curing, the waterproof film formed by the coating has certain extensibility, elasticity, crack resistance, impermeability, and weather resistance, and can play a role in waterproofing, seepage prevention, and protection.

[0042] Waterproof membrane: Water-based epoxy resin moisture-proof film is used instead of waterproof membrane. It is environmentally friendly, uses water as a solvent, and the odorless paint film is permeable to water vapor and has dustproof and mildew-proof properties.

[0043] Water-sensitive color-changing inks: based on the mechanism of pigment and solvent separation. A special pigment is added to the coating; this pigment is insoluble in water but compatible with other coating components. When moisture comes into contact with the coating surface, the moisture penetrates the coating and causes the pigment to separate from it, resulting in a color change.

[0044] Furthermore, a method for waterproofing the exterior walls of a basement includes:

[0045] Real-time data on the waterproofing structure of the basement is collected through a basement waterproofing and damp-proofing monitoring system.

[0049] Furthermore, the electro-osmotic waterproofing system, after applying low voltage and low current pulse charges through the central control box, forms an electric field between the positive and negative electrodes, causing the hydrated ions and water molecules in the diffusion layer to detach from the negative electric field on the surface of the soil particles in the pore structure. This causes the hydrated ions and water molecules to move along the direction of the electric field force along the pore structure towards the negative electrode, thereby expelling the water.

[0050] The basement waterproofing and damp-proofing monitoring system includes: sensors and a basement management server. The sensors collect real-time data and communicate with the basement management server through Internet of Things (IoT) technology. The basement management server uses big data technology to analyze and summarize the data, and predict and analyze the water seepage situation in the basement.

[0051] The drainage system includes: an edge drainage and water conveyance system, an internal buried pipe drainage system, and a groundwater system. The edge drainage and water conveyance system, the internal buried pipe drainage system, and the groundwater system are connected in sequence. The internal buried pipe drainage system carries out drainage by burying pipes inside the waterproof structure of the basement. The edge drainage and water conveyance system buries and discharges water at the edge of the waterproof structure of the basement. The groundwater system connects to the edge drainage and water conveyance system outside the waterproof structure of the basement through buried pipes to draw water in and drain water, and discharges the accumulated water in the edge drainage and water conveyance system into the groundwater system.

[0052] In a specific implementation, a schematic diagram of a basement waterproofing structure is shown, as follows: Figure 1 As shown, it includes:

[0053] The foundation pit includes the bottom of the foundation pit, the edge of the foundation pit 7, and the outer wall of the basement 4.

[0054] like Figure 2As shown, the edge drainage water supply system, the internal buried pipe drainage system, and the groundwater system are connected in sequence. The internal buried pipe drainage system drains water through the internal buried pipe 13 inside the waterproof structure of the basement. The edge drainage water supply system drains water through the edge drain pipe 12 at the edge of the waterproof structure of the basement. The groundwater system connects to the edge drainage water supply system outside the waterproof structure of the basement through buried pipes to draw water in and drain water, and discharges the water accumulated in the edge drainage water supply system into the groundwater system.

[0055] The interior wall of the basement exterior wall 11 is painted by mixing water-sensitive ink with wall paint.

[0056] In a specific implementation, a construction diagram of a basement exterior wall is shown, as follows: Figure 3 As shown, it includes:

The exterior wall 4 of the basement is then subjected to internal corner treatment with a PVC waterproof layer, internal corner treatment with a PVC counter-pressure layer, and internal corner sealing layer in sequence.

The pit backfill soil between the positive electrode plate 6 and the negative electrode plate 5 is filled by adding two-component water-based epoxy resin to the concrete.

[0060] Furthermore, this also includes the use of water-based epoxy resin moisture-proof membranes for waterproof membrane construction; and the use of polymer cement elastic waterproof coatings or penetrating crystalline waterproof coatings for waterproof coating construction.

[0061] After applying low-voltage and low-current pulse charges through the central control box, the positive electrode plate 6 is placed on the outside of the waterproof and seepage-proof material on the wall, close to the backfill soil of the foundation pit. The negative electrode plate 5 is placed on one side of the backfill soil and the edge 7 of the foundation pit. A stable low-voltage electric field is formed outside the structure, causing water molecules and hydrated ions to move from the positive electrode to the negative electrode, thereby expelling moisture from the structure and preventing moisture from the outside from entering the structure, thus preventing the structure from being affected by leakage and dampness.
