Technical Field

[0001] The invention belongs to the technical field of building leakage monitoring, and in particular relates to an intelligent waterproofing coiled material based on optical fiber grating and a monitoring method. Background Art

[0002] As the construction industry ushered in tremendous development, it gradually became an important driving force for my country's national economy. The possibility and importance of rational use of building roof space are gradually being recognized. The difficulty in dealing with building leakage problems lies in the difficulty of accurately locating the leakage location and finding the damaged point of the membrane, and the timeliness of the treatment is poor, resulting in the safety hazard of long-term water leakage in the building. Building leakage has always been a major pain point in the current building waterproofing industry. Building leakage is extremely harmful and the leakage rate remains high. It is difficult to locate the source of leakage during the leakage treatment process, which will lead to the failure of the internal structural layer of the building. In addition, it is difficult and expensive to plug the leak in the later stage.

[0003] Therefore, in order to solve the above problems, an intelligent waterproof membrane based on fiber grating and a monitoring method are proposed. Summary of the invention

[0004] The purpose of the present invention is to provide an intelligent waterproof membrane based on fiber grating and a monitoring method to solve the problems raised in the above-mentioned background technology, solve the problems such as huge harm to building leakage, high leakage rate, difficulty in locating the leakage source, and high cost of plugging leakage. An intelligent waterproof membrane based on fiber grating and a monitoring method are proposed to effectively solve the problem of accurate positioning of leakage.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An intelligent waterproofing coiled material based on fiber grating comprises a structural layer and a waterproofing coiled material base layer, wherein the structural layer is bonded to the bottom of the waterproofing coiled material base layer; a non-woven double-sided adhesive layer, a mixed layer and a honeycomb waterproofing adhesive paper layer are sequentially laid on the waterproofing coiled material;

[0007] The mixed layer includes polyester resin, fiber Bragg grating and EVA copolymer resin, the fiber Bragg grating is located between the polyester resin and the EVA copolymer resin; and the EVA copolymer resin is suitable for sealing the fiber Bragg grating on the polyester resin; the honeycomb waterproof adhesive tape is laid on the EVA copolymer resin.

[0008] A monitoring method based on fiber grating intelligent waterproofing coiled material comprises the following steps:

[0009] Step 1: After the waterproofing membrane is constructed, mark the overlapping area and the structural stress position on the surface of the waterproofing membrane, mark the stress area, and paste the non-woven double-sided tape on the surface of the waterproofing membrane base;

[0010] Step 2: Paste a polyester resin strip on the double-sided adhesive area of ​​the non-woven fabric, and use the good mechanical properties, corrosion resistance, and air and water barrier functions of the polyester resin as a supporting baseband for the fiber Bragg grating on the waterproof roll;

[0011] Step 3, laying the fiber Bragg grating on the polyester resin strip, and sealing the fiber Bragg grating on the polyester resin strip with EVA copolymer resin, and using the sealed pore structure of the EVA copolymer resin to protect the fiber Bragg grating from external damage;

[0012] Step 4: Use honeycomb waterproof tape to stick on the fiber Bragg grating sensor to prevent the fiber Bragg grating from being completely exposed to the outside, so as to protect the monitoring signal optical fiber and prevent the fiber Bragg grating from being corroded by the external environment;

[0013] Step 5: After the fiber Bragg grating sensors are connected in series with armored cables, the wavelength data is obtained through the FBG demodulator. The leakage positioning monitoring system and the visual monitoring platform form a leakage monitoring system, which can effectively monitor the leakage conditions inside the building and accurately locate the leakage point and range.

[0014] The present invention embeds a fiber Bragg grating sensor into a traditional waterproofing membrane to realize the leakage location detection function. The intelligent waterproofing membrane is used as the basic monitoring sensing unit, and the leakage location monitoring system and the visual monitoring platform form a leakage monitoring system. The intelligent waterproofing membrane sensing unit collects information, collects the internal leakage information of the building, uses STM32 as a microprocessor to complete the leakage location alarm host, and displays the specific location on the visual monitoring platform, so as to analyze the cause of the leakage and accurately plug the leak.

[0015] Furthermore, a ceramic heating tube is installed outside the fiber Bragg grating sensor, and a plurality of fiber Bragg sensors are provided, and the groups are connected by installing armored optical fibers;

[0016] A monitoring tube is arranged on the outer jacket of the ceramic heating tube, and the monitoring tube is suitable for covering a plurality of groups of fiber Bragg grating sensors and armored optical fibers.

[0017] Furthermore, a temperature measuring point is formed at the location of each grating of the fiber Bragg grating, and the gratings are arranged every 15 cm; the monitoring tube is made of carbon fiber material, and the temperature of the carbon fiber layer increases when power is turned on. The temperature of the leakage point will produce heat exchange with the size of the leakage to take away part of the heat. The fiber Bragg grating sensor captures the temperature distribution of the temperature measuring point, and after analysis, it accurately locates and monitors the leakage position and range.

[0018] Furthermore, the waterproof coiled material is provided with an overlap area, and the overlap areas of adjacent waterproof coiled materials are divided into upper and lower installations;

[0019] One group of overlapping areas is equipped with a first connector, and the other group is equipped with a second connector; the first connector and the second connector are adapted to each other.

[0020] Further, the connecting member 1 is a notch plate, the notch plate comprises a first sub-plate and a second sub-plate, and the first sub-plate and the second sub-plate are both provided with an arc-shaped opening 1 and an arc-shaped opening 2; the diameter of the arc-shaped opening 1 is greater than the diameter of the arc-shaped opening 2;

[0021] The first and second split plates are installed in pairs at the ends and are provided with adjusting bolts;

[0022] The second connecting member comprises a soft board 1, on which a connecting column is installed. The connecting column is in a "T" shape and is suitable for connecting in two sets of arc-shaped openings 1 installed oppositely.

[0023] Furthermore, the diameter of the arc-shaped opening 1 is smaller than the top diameter of the connecting column; in step 5, glue is injected into the outside of the connecting member 1 to bond the overlapping areas of the two sets of waterproof membranes.

[0024] The first aspect of the present invention is to provide a fiber Bragg grating leakage monitoring sensor having the following characteristics, including:

[0025] 1) The fiber grating leakage monitoring sensor uses a temperature tracer method to monitor the leakage of the building waterproof layer, monitor the integrity of the waterproof layer, and check the leakage after the leakage occurs to facilitate successful plugging.

[0026] 2) The fiber grating leakage monitoring sensor can be applied to leakage detection of waterproof projects, can accurately locate the damaged point of the coiled material, and has high timeliness, effectively solving the problem of accurate positioning of leakage inside the building.

[0027] 3) The fiber Bragg grating leakage monitoring sensor uses distributed optical fiber-based temperature sensing technology to identify the leakage of the waterproof layer, and determines the leakage state by the phenomenon that the temperature field near the leakage channel is significantly different from that in the normal leakage state.

[0028] 4) The fiber Bragg grating leakage monitoring sensor can identify leakage status by utilizing the sudden change of temperature field near the leakage location, as the heat exchange caused by leakage will take away part of the heat. Accurate temperature monitoring can provide higher spatial leakage location characteristics.

[0029] 5) The fiber grating leakage monitoring sensor adopts a point heat source leakage monitoring method and multi-point distributed heating to reduce the heating power demand. At the same time, it uses the cooling characteristics of the heat source to determine the leakage state, which can improve the stability and accuracy of monitoring.

[0030] The second aspect of the present invention is to provide the above-mentioned fiber grating intelligent waterproofing membrane monitoring system, which uses the intelligent waterproofing membrane as the basic monitoring sensor unit, and forms a leakage monitoring system with the leakage positioning monitoring system and the visual monitoring platform. During the waterproofing construction phase, the intelligent sensing unit is laid inside the building to build an intelligent monitoring system, which can be used for waterproofing layer construction and can also be used to check leakage inside the building at any time.

[0031] The third aspect of the present invention is to provide a fiber grating-based intelligent waterproofing coiled material structure having the following characteristics, including:

[0032] 1) A fiber Bragg grating-based intelligent waterproofing coiled material structure, whose structural features from top to bottom include: honeycomb waterproof adhesive tape, fiber Bragg grating sensor, EVA copolymer resin, polyester resin, and non-woven double-sided adhesive.

[0033] 2) The honeycomb waterproof adhesive tape of the fiber Bragg grating intelligent waterproof coiled material structure described above is used to prevent the fiber Bragg grating from being completely exposed, thereby protecting the fiber Bragg grating sensor and preventing corrosion from the external environment;

[0034] 3) The fiber Bragg grating intelligent waterproofing coiled material structure described above has a fiber Bragg grating sensor that is spaced to set a measuring point sensor, and the sensor is added with a ceramic heating tube heating unit. The fiber Bragg grating sensor is connected in series with an armored optical cable, and the wavelength data is obtained by means of an FGB demodulator and transmitted to a leakage positioning monitoring system to visually monitor the precise position and range of the leakage point;

[0035] 4) The fiber Bragg grating intelligent waterproof coiled material structure described above has an EVA copolymer resin characterized by a sealed pore structure, excellent waterproof performance, shock resistance, and corrosion resistance, and plays a sealing and protective role for the fiber Bragg grating sensor;

[0036] 5) The fiber Bragg grating-based intelligent waterproof coiled material structure, wherein the polyester resin is used as a supporting base band of the optical fiber in the fiber Bragg grating sensor by utilizing its good mechanical properties, corrosion resistance, and air and water barrier functions;

[0037] 6) The non-woven double-sided adhesive tape of the fiber grating-based intelligent waterproofing coiled material structure has good adhesion to rubber and plastic materials, and is used in the present invention to make the fiber grating sensor and the traditional waterproofing coiled material tightly bonded.

[0038] 7) In the fiber Bragg grating-based intelligent waterproofing membrane structure, honeycomb-shaped holes are reserved above the honeycomb waterproofing tape. When the holes are flooded by leaking water, the seepage will shuttle between the honeycomb-shaped holes, and the generated heat exchange will take away part of the heat. The fiber Bragg grating sensor below senses the sudden change of the nearby temperature field to identify the leakage state.

[0039] Beneficial Effects

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The present invention is based on a fiber grating intelligent waterproofing membrane and a monitoring method. Through intelligent waterproofing membrane monitoring, a leakage positioning monitoring system and a visual monitoring platform form a leakage monitoring system, which can effectively monitor the leakage conditions inside the building and accurately locate the leakage point and range.

[0042] (2) The fiber grating intelligent waterproofing membrane and monitoring method of the present invention are more difficult to accurately locate the damaged point of the membrane than in the past, which leads to the hidden danger of long-term waterlogging in buildings. A real-time leakage monitoring method is described to monitor leakage, and the leakage state is judged by the difference between the temperature field near the leakage channel and the normal seepage state.

[0043] (3) The fiber Bragg grating intelligent waterproofing membrane and monitoring method of the present invention adopts a fiber Bragg grating sensor. Compared with the traditional leakage detection, the fiber Bragg grating sensor has higher accuracy and can more accurately sense the temperature field changes near the leakage location, directly detect the leakage inside the building, and locate the leakage source more accurately.

[0044] (4) Compared with the traditional leakage detection method, the fiber grating intelligent waterproofing membrane and monitoring method of the present invention can detect leakage in the building at any time by laying intelligent sensor units and setting up an intelligent monitoring system during the waterproofing construction stage, thereby continuously improving the waterproofing strength of the intelligent waterproofing system.

[0045] (5) The present invention is a fiber Bragg grating intelligent waterproofing membrane and monitoring method, which adopts a structure of a fiber Bragg grating sensor wrapped with carbon fiber. The water flow at the leakage point causes the temperature of the area around the temperature measuring point to change. The fiber optic sensor captures the ambient temperature change and analyzes the leakage speed and position. Compared with the past, it is difficult to find the leakage position, and blind plugging is used to achieve the purpose of repairing the waterproof layer. The intelligent technology support makes the leakage monitoring reasonable and effective.

[0046] (6) The present invention is a fiber Bragg grating-based intelligent waterproofing membrane and monitoring method, which utilizes the temperature tracing method of a fiber Bragg grating sensor and the temperature sensing technology of a distributed optical fiber to identify leakage status. The FBG-based point heat source seepage monitoring method uses multi-point distributed heating to reduce the heating power requirement. At the same time, the heat source cooling characteristics are used to identify the leakage status, which can eliminate the influence of uneven resistance on the identification result and improve the stability and accuracy of the monitoring system.

[0060] A monitoring method based on fiber grating intelligent waterproofing coiled material comprises the following steps:

[0061] Step 1: After the waterproofing membrane is constructed, mark the overlapping area 11 and the structural stress position on the surface of the waterproofing membrane, mark the stress area, and paste the non-woven double-sided tape on the surface of the waterproofing membrane base 2; its function is to better bond the rubber and plastic materials and ensure that the fiber Bragg grating sensor is tightly bonded to the waterproofing membrane.

[0062] Step 2, stick 4 strips of polyester resin on the double-sided adhesive area of ​​the non-woven fabric, and use the good mechanical properties, corrosion resistance, and air and water barrier functions of the polyester resin 4 as the supporting base tape of the fiber Bragg grating 7 on the waterproof coiled material to prevent the fiber Bragg grating from being broken due to the tensile stress of the waterproof coiled material;

[0063] Step 3, laying the fiber Bragg grating 7 on the polyester resin 4 strips, and sealing the fiber Bragg grating 7 on the polyester resin 4 strips with EVA copolymer resin 5, and using the sealed pore structure of the EVA copolymer resin 5 to protect the fiber Bragg grating 7 from external damage;

[0065] Step 5: After the fiber Bragg grating 7 sensors are connected in series with armored cables, the wavelength data is obtained through the FBG demodulator. The leakage positioning monitoring system and the visual monitoring platform form a leakage monitoring system, which can effectively monitor the leakage conditions inside the building and accurately locate the leakage point and range.
