Description

Technical Field

[0001] The invention relates to the technical field of earthquake damage to a multi-cabin structure of an underground utility gallery, and in particular to a comprehensive observation device for earthquake damage experiments on a multi-cabin structure of an underground utility gallery. Background Art

[0002] Urban underground utility corridors can not only solve the problem of urban traffic congestion, but also greatly facilitate the maintenance and inspection of municipal facilities such as electricity, communications, gas, water supply and drainage. However, it also brings a series of new safety issues: first, multiple dangerous sources coexist in the corridor, especially high-risk pipelines such as gas, heat, and high-voltage electricity; second, the underground utility corridor itself is particularly vulnerable to certain external disasters, such as earthquakes and geological disasters.

[0003] At present, there are few technical solutions related to earthquake damage experiments of urban underground utility corridors. The existing experimental device has studied the stress and strain of underground utility corridors during earthquakes, but the experimental device is a corridor model with a single-compartment structure. The purpose of the existing multi-compartment structure experiment is to obtain basic physical parameters such as stress, strain and acceleration, without focusing on observing the damage of the corridor structure.

[0004] The current experiments all focus on the structural response of the pipeline corridor under the single disaster of earthquake, which is a study based on the perspective of building structure. From the perspective of safety assessment, the most unfavorable scenario for underground integrated pipeline corridors is a multi-disaster coupling accident. In order to minimize the possibility of multi-disaster coupling, the underground integrated pipeline corridor design adopts a compartment structure, which separates high-risk pipelines such as gas into compartments and physically isolates them from other pipelines. However, under earthquake conditions, structures such as partition walls may be damaged or cracked, thereby making the physical isolation ineffective and posing the risk of gas leakage to adjacent compartments.

[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0051] The following describes a comprehensive observation device 1000 for earthquake damage experiments of multi-cabin structures in underground utility corridors according to an embodiment of the present invention.

[0052] like Figure 1 and Figure 2 As shown, according to an embodiment of the invention, a comprehensive observation device 1000 for earthquake damage experiment of multi-cabin structure of underground pipeline gallery includes an underground pipeline gallery multi-cabin structure experimental model 1, an inflation device 2, a data acquisition instrument component 3 and an experimental display and analysis terminal 4; the underground pipeline gallery multi-cabin structure experimental model 1 is a concrete structure and has a plurality of cabins 11, the plurality of cabins 11 are isolated from each other and extend in the same direction, the two ends of the plurality of cabins 11 are sealed, and one cabin 11 of the plurality of cabins 11 is a gas cabin 111; the inflation device 2 is used to fill the gas cabin 111 with tracer gas according to the requirements of the earthquake damage experiment; the data acquisition instrument component 3 is used to detect the leakage of tracer gas in the gas cabin 111 according to the requirements of the earthquake damage experiment; the experimental display and analysis terminal 4 is used to receive and analyze the tracer gas leakage detection information of the data acquisition instrument component 3, and obtain the damage analysis result of the underground pipeline gallery multi-cabin structure experimental model 1, and the experimental display and analysis terminal 4 is also used to display the damage analysis result.

[0053] Specifically, the underground pipeline corridor multi-cabin structure experimental model 1 is a concrete structure and has a plurality of cabins 11. The plurality of cabins 11 are isolated from each other and extend in the same direction. Both ends of the plurality of cabins 11 are sealed, and one of the cabins 11 is a gas cabin 111. It can be understood that the underground pipeline corridor multi-cabin structure experimental model 1 is made of concrete, which can better restore the real underground pipeline corridor multi-cabin structure and ensure the reliability of the experimental results; since the underground pipeline corridor includes a variety of pipelines, among which gas pipelines, thermal pipelines, high-voltage power pipelines, etc. are high-risk pipelines, when a plurality of cabins 11 are provided in the underground pipeline corridor multi-cabin structure experimental model 1, the high-risk pipelines such as gas pipelines, thermal pipelines, high-voltage power pipelines, etc. can be separately arranged in a cabin 11 and physically isolated from other pipelines, which can avoid the possibility of coupling of multiple disasters to the greatest extent and improve the underground pipeline corridor. The safety of the underground utility corridor. Further, the underground utility corridor multi-cabin structure experimental model 1 may include four cabins 11, and the two ends of the multiple cabins 11 are sealed. The wall damage of the underground utility corridor multi-cabin structure experimental model 1 caused by earthquake can be studied in the experiment. For example, when cracks appear in the wall of the gas cabin 111, the accident scenario and disaster mechanism of gas leakage to the adjacent cabin 11 or the outside world can be studied; the outermost cabin 11 of the underground utility corridor multi-cabin structure experimental model 1 is used as the gas cabin 111, which can conveniently detect the attenuation law of gas leakage and diffusion in the underground utility corridor multi-cabin structure.

[0054] The gas filling device 2 is used to fill the gas chamber 111 with tracer gas according to the requirements of the earthquake damage experiment. It is understandable that during the experiment, since natural gas is a flammable and explosive gas, it is not suitable for direct use in the gas leakage detection experiment. Therefore, the gas chamber 111 is filled with tracer gas through the gas filling device 2, and the tracer gas is used to replace the natural gas in the actual situation, which can ensure the safety of the experiment. At the same time, by detecting the tracer gas, it is possible to detect whether the gas chamber 111 is leaking, which is convenient for detection.

[0055] It should be noted that the tracer gas can be SF6 gas. SF6 gas is an inert gas with strong chemical stability. It does not decompose under high temperature conditions of 500-600°C and does not react with acids, alkalis, salts, ammonia, water, etc. At the same time, SF6 gas has high detection sensitivity. When SF6 gas is used as a tracer gas for leak detection, the detection results are reasonable and reliable, and the experimental accuracy is high.

[0056] The data acquisition instrument assembly 3 is used to detect the tracer gas leakage in the gas chamber 111 according to the earthquake damage experiment requirements. It can be understood that the tracer gas leakage in the gas chamber 111 can be detected by detecting the tracer gas concentration changes inside and outside the multiple chambers 11 through the data acquisition instrument.

[0057] The experimental display and analysis terminal 4 is used to receive and analyze the tracer gas leakage detection information of the data acquisition instrument component 3, and obtain the damage analysis result of the underground pipeline gallery multi-cabin structure experimental model 1. The experimental display and analysis terminal 4 is also used to display the damage analysis result. In this way, the damage of the underground pipeline gallery multi-cabin structure experimental model 1 can be analyzed and displayed in real time through the experimental display and analysis terminal 4, which is intuitive and convenient.

[0058] According to the comprehensive observation device 1000 for earthquake damage experiment of multi-cabin structure of underground pipeline gallery according to the embodiment of the present invention, there are two experimental methods. The first experimental method is to simultaneously conduct vibration experiment and data collection of the experimental model 1 of the multi-cabin structure of the underground pipeline gallery, wherein, before the experiment starts, the data acquisition instrument component 3 is firstly arranged inside and outside the multiple cabins 11, and the two ends of the multiple cabins 11 are sealed, and the tracer gas is filled into the gas cabin 111 through the inflation device 2 according to the requirements of the earthquake damage experiment, and then the vibration experiment is carried out on the experimental model 1 of the multi-cabin structure of the underground pipeline gallery. During the vibration experiment, the tracer gas leakage in the gas cabin 111 is detected according to the requirements of the earthquake damage experiment through the data acquisition instrument component 3 and the detection result is transmitted to the experimental display and analysis terminal 4, the experimental display and analysis terminal 4 receives and analyzes the tracer gas leakage detection information of the data acquisition instrument component 3, and obtains the damage analysis result of the experimental model 1 of the multi-cabin structure of the underground pipeline gallery. The display and analysis terminal 4 also displays the damage analysis results; the second experimental method is to first conduct a vibration experiment on the underground pipeline corridor multi-cabin structure experimental model 1, and then conduct data collection on the underground pipeline corridor multi-cabin structure experimental model 1, wherein the underground pipeline corridor multi-cabin structure experimental model 1 is first subjected to a vibration experiment. After the vibration experiment is completed, the data acquisition instrument component 3 is arranged inside and outside the multiple cabins 11, and the two ends of the multiple cabins 11 are sealed, and tracer gas is filled into the gas cabin 111 through the inflation device 2 according to the requirements of the earthquake damage experiment, and the tracer gas leakage in the gas cabin 111 is detected through the data acquisition instrument component 3 according to the requirements of the earthquake damage experiment and the detection result is transmitted to the experimental display and analysis terminal 4, the experimental display and analysis terminal 4 receives and analyzes the tracer gas leakage detection information of the data acquisition instrument component 3, and obtains the damage analysis result of the underground pipeline corridor multi-cabin structure experimental model 1, and the experimental display and analysis terminal 4 also displays the damage analysis result.

[0059] According to the embodiment of the present invention, the comprehensive observation device 1000 for earthquake damage experiments of underground utility corridor multi-cabin structures can analyze and display the damage and gas leakage of the underground utility corridor multi-cabin structure experimental model 1 in real time, so as to study the accident scenarios and disaster-causing mechanisms of the damage to the underground utility corridor multi-cabin structure in earthquake disasters and the gas leakage caused by the damage to the underground utility corridor multi-cabin structure, and the experimental results are accurate and safe.

[0060] According to one embodiment of the present invention, sealing partitions 12 are provided at both ends of the underground pipe gallery multi-cabin structure experimental model 1 to seal both ends of the multiple cabins 11. It can be understood that the sealing partitions 12 are fixed to both ends of the multiple cabins 11 by fixing bolts to seal the multiple cabins 11, so as to facilitate the accident scenario and disaster mechanism of gas leakage to adjacent cabins 11 or the outside world when cracks appear in the wall of the gas cabin 111 of the underground pipe gallery multi-cabin structure experimental model 1 caused by an earthquake in the experiment.

[0061] According to one embodiment of the present invention, the plurality of compartments 11 are arranged in a linear manner, so that the structure is reasonable and the arrangement is convenient.

[0062] According to one embodiment of the present invention, the data acquisition instrument assembly 3 includes a plurality of infrared quantitative detectors 31 for tracer gas concentration, and a portion of the plurality of infrared quantitative detectors 31 for tracer gas concentration are correspondingly distributed in the remaining cabins 11 of the plurality of cabins 11 except the gas cabin 111, so as to respectively detect the concentration of the tracer gas in the corresponding cabins 11, and the remaining portion of the plurality of infrared quantitative detectors 31 for tracer gas concentration are correspondingly distributed on the outer sides and the outer top side of the underground corridor multi-cabin structure experimental model 1, so as to respectively detect the concentration of the tracer gas outside the plurality of underground corridor multi-cabin structure experimental models 1. Specifically, the number of infrared quantitative detectors 31 for tracer gas concentration is selected according to the number of cabins 11 of the underground corridor multi-cabin structure experimental model 1, such as Figure 1 and Figure 2 As shown, there are six infrared quantitative detectors 31 for tracer gas concentration. The outermost compartment 11 of the underground pipe gallery multi-cabin structure experimental model 1 is used as the gas compartment 111. The three infrared quantitative detectors 31 for tracer gas concentration are respectively and one by one arranged in the other three compartments 11 except the gas compartment 111. For example, the three infrared quantitative detectors 31 for tracer gas concentration can be respectively and one by one arranged on the top walls of the other three compartments 11 except the gas compartment 111. The infrared quantitative detectors 31 for tracer gas concentration can be used to conveniently detect the corresponding The concentration of the tracer gas in the cabin 11 can be used to determine whether the wall of the corresponding cabin 11 has structural damage that may cause tracer gas leakage. In addition, based on the detection results of the tracer gas concentration infrared quantitative detector 31, the attenuation law of gas leakage and diffusion in the multi-cabin structure of the underground corridor can be studied; the remaining three tracer gas concentration infrared quantitative detectors 31 are respectively set on the external sides and external top side of the underground corridor multi-cabin structure experimental model 1 to detect whether the tracer gas has leaked to the outside of the underground corridor multi-cabin structure experimental model 1.

[0063] According to a further embodiment of the present invention, a part of the plurality of infrared quantitative tracer gas concentration detectors 31 transmits the tracer gas leakage detection information to the experimental display and analysis terminal 4 via wireless transmission, and the remaining part of the plurality of infrared quantitative tracer gas concentration detectors 31 transmits the tracer gas leakage detection information to the experimental display and analysis terminal 4 via wired transmission. Specifically, Figure 1 and Figure 2 As shown, the three infrared quantitative detectors 31 for tracer gas concentration located inside the cabin 11 can transmit the tracer gas leakage detection information to the experimental display and analysis terminal 4 through the wireless transceiver module respectively. In this way, the structure is reasonable and it is convenient to seal multiple cabins 11; the three infrared quantitative detectors 31 for tracer gas concentration located outside the cabin 11 can transmit the tracer gas leakage detection information to the experimental display and analysis terminal 4 through the data transmission line respectively.

[0064] It should be noted that the remaining tracer gas concentration infrared quantitative detectors 31 among the multiple tracer gas concentration infrared quantitative detectors 31 also have sound and light alarm functions. Specifically, the three tracer gas concentration infrared quantitative detectors 31 located outside the cabin 11 have sound and light alarm functions. When tracer gas leakage to the outside of the cabin 11 is detected, an alarm is issued so that ventilation equipment can be started in time and emergency treatment can be carried out to ensure the safety of the experiment.

[0065] According to one embodiment of the present invention, the data acquisition instrument assembly 3 is also used to detect cracks in the underground utility corridor multi-cabin structure experimental model 1 according to the earthquake damage test requirements. It can be understood that when cracks occur in the walls of multiple compartments 11 of the underground utility corridor multi-cabin structure experimental model 1 but no tracer gas leakage occurs, the data acquisition instrument assembly 3 can more comprehensively detect the structural damage of the underground utility corridor multi-cabin structure experimental model 1, and the experimental results are more reliable.

[0066] According to a further embodiment of the present invention, the data acquisition instrument component 3 also includes a plurality of intelligent crack scanners 32, each of which has its own lighting device. A portion of the plurality of intelligent crack scanners 32 are correspondingly distributed in a plurality of cabins 11 to detect crack conditions on the inner wall surfaces of the corresponding cabins 11, and the remaining portion of the plurality of intelligent crack scanners 32 are correspondingly distributed on the outer sides and outer top side of the underground utility corridor multi-cabin structure experimental model 1 to detect crack conditions on the outer wall surfaces of the underground utility corridor multi-cabin structure experimental model 1. Specifically, the number of intelligent crack scanners 32 is selected according to the number of cabins 11 of the underground utility corridor multi-cabin structure experimental model 1, such as Figure 1 and Figure 2As shown, there are seven intelligent crack scanners 32, and four intelligent crack scanners 32 are respectively and one-to-one arranged in the four cabins 11. For example, the four intelligent crack scanners 32 can be respectively and one-to-one arranged on the bottom walls of the four cabins 11, so that the four intelligent crack scanners 32 can better scan the cracks on the inner wall surfaces of the corresponding cabins 11; the three intelligent crack scanners 32 are respectively and correspondingly arranged on the outer sides and the outer top side of the underground corridor multi-cabin structure experimental model 1, so as to conveniently detect the cracks on the outer wall surfaces of multiple underground corridor multi-cabin structure experimental models 1; the multiple intelligent crack scanners 32 all have their own lighting devices, which can be illuminated when the brightness is insufficient, so as to facilitate the detection of cracks on the inner wall surfaces of the cabins 11 and cracks on the outer wall surfaces of the underground corridor multi-cabin structure experimental model 1, and the detection results are accurate and reliable.

[0067] It should be noted that a part of the multiple intelligent crack scanners 32 sends the crack conditions of the inner wall surface of the cabin 11 to the experimental display and analysis terminal 4 through wireless transmission, and the remaining part of the multiple intelligent crack scanners 32 sends the crack conditions of the outer wall surface of the underground corridor multi-cabin structure experimental model 1 to the experimental display and analysis terminal 4 through wired transmission. Specifically, Figure 1 and Figure 2 As shown, the three intelligent crack scanners 32 located inside the cabin 11 can transmit the crack conditions of the inner wall of the cabin 11 to the experimental display and analysis terminal 4 through the wireless transceiver module. In this way, the structure is reasonable and it is convenient to seal multiple cabins 11; the three intelligent crack scanners 32 located outside the cabin 11 can transmit the crack conditions of the outer wall of the underground corridor multi-cabin structure experimental model 1 to the experimental display and analysis terminal 4 through the data transmission line.

It can be understood that the three-axis panoramic image stabilization brushless gimbal 33 has an automatic stabilization function, and the influence of the vibration pile intelligent crack scanner 32 in the experiment can be greatly reduced by installing some of the multiple intelligent crack scanners 32 on the multiple three-axis panoramic image stabilization brushless gimbals 33, thereby improving the accuracy of the experiment; specifically, there are four three-axis panoramic image stabilization brushless gimbals 33, and the four three-axis panoramic image stabilization brushless gimbals 33 are fixedly arranged on the bottom walls of the four cabins 11 one by one, and the four intelligent crack scanners 32 are respectively and one by one installed on the three-axis panoramic image stabilization brushless gimbal 33.
