[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0027] It should be noted that the open-cut prefabricated and assembled subway station in the embodiment of the present application, wherein the subway station body can be composed of multiple prefabricated components, and the assembled station body can include top-level components, middle-level components and bottom-level components. The use of open-cut prefabricated construction method can shorten the construction period, improve construction efficiency and reduce costs.

[0028] The above-mentioned middle-layer components can be called side walls, and the side walls can be assembled by assembling several sections of lining rings. When assembling the side walls, usually every time several sections of lining rings are assembled, the fertilizer trough on one side of the side wall needs to be backfilled. The quality of the fertilizer trough backfill has a key impact on the prefabricated structure, the stress of the joints, and the stability of the structural system. During the fertilizer trough backfill stage, the backfill materials and the density of the fertilizer trough backfill have a significant impact on the internal force, deformation and displacement of the prefabricated structure. Poor fertilizer trough backfill may cause the main body of the station (i.e. the station body) to settle, affecting the stability of the components and the waterproof performance of the station, thereby causing serious safety problems. Therefore, the quality of the fertilizer trough backfill must be guaranteed.

[0029] The multiple prefabricated components in the main body of the subway station in the embodiment of the present application are assembled structural components, such as Figure 1 As shown, the assembly structure components include: a station bottom plate 1, a strain sensor 2, a microseismic sensor 3, a station side wall block 4, and a station top plate 5;

[0030] Every N station floor panels 1 are assembled into a loop, and strain sensors 2 are set on the side of the odd-numbered station floor panels in a loop, and microseismic sensors 3 are set on the side of the even-numbered station floor panels in a loop; the assembly structure assembly includes multiple loops; N is a positive integer;

[0031] In a specific example, the value of N can be determined according to actual needs. For example, the value is 8, which means that every 8 station floors form a cycle. Figure 2 As shown in the figure, it is a schematic diagram of the assembly cycle of the assembly structure components. Figure 2 There are 3 assembly cycles in it.

[0032] Station side wall blocks 4 are hoisted on both sides of each station floor block, and station top blocks 5 are set on the two station side wall blocks of the same station floor block;

[0033] Two strain sensors 2 are evenly spaced on the station side wall blocks 4 corresponding to the odd-numbered station floor blocks 1 in a cycle, and two microseismic sensors 3 are evenly spaced on the station side wall blocks 4 corresponding to the even-numbered station floor blocks 1 in a cycle.

[0034] Further, such as Figure 3 As shown, the station roof block 5 in the embodiment of the present application includes a first ring dome block 51 and a second ring dome block 52;

[0035] The first ring arch block 51 and the second ring arch block 52 are aligned and locked on the two station side wall blocks 4 of the same station floor block;

[0036] A microseismic sensor 3 is provided on the first annular dome block 51 , and a microseismic sensor 3 is provided on the second annular dome block 52 .

[0037] The following is a detailed description of the assembly process of the assembly structure components in the embodiment of the present application. After the foundation pit of the subway station is excavated to the bottom and the concrete cushion layer is poured, the assembly section structure assembly construction begins. The process includes the following steps:

[0038] Step 101: assemble the station floor panels 1, install strain sensors 2 on the assembled odd-numbered station floor panels 1, and install microseismic sensors 3 on the even-numbered station floor panels 1. Each assembly of 8 station floor panels 1 constitutes a cycle. Figure 4 As shown, the strain sensor 2 and the microseismic sensor 3 are closely mounted on the assembly structure component (ie, the station body). After the strain sensor 2 and the microseismic sensor 3 are installed, the troughs on both sides of the station floor plate 1 and the inverted arch are backfilled.

[0039] Step 102: After the station floor panel 1 is assembled, the first ring center column and the center longitudinal beam are assembled. After the assembly is completed, the first ring station side wall panel 4 is hoisted so that the side wall panel 4 gradually approaches the predetermined position and settles on the station floor panel 1 after fine-tuning. Then, the strain sensor 2 is installed on the station side wall panel 4. The installation position of the strain sensor 2 can be located at 1 / 3 and 2 / 3 of the height of the station side wall panel 4. For details, see Figure 5 .

[0040] Step 103, after the installation of the side wall block 4 of the first ring station is completed, the upper trolley is installed, the upper trolley is lifted by the hydraulic system, the left eccentric ring arch block 51 and the right eccentric ring arch block 52 are hoisted, the left eccentric ring arch block 51 and the right eccentric ring arch block 52 are aligned and locked, close to the predetermined position, and then installed and settled on the side wall block 4 of the first ring station. The strain sensor 2 is installed just above the tenon connection of the left eccentric ring arch block 51 and the right eccentric ring arch block 52, and the microseismic sensor 3 is installed in the center of the top of the left eccentric ring arch block 51 and the right eccentric ring arch block 52. Here, the strain sensor 2 and the microseismic sensor 3 are used to monitor the backfill quality of the backfill soil above the station and the deformation state of the station. For details, see Figure 5 .

[0041] Step 104, after the first ring components are assembled, during the assembly of the second ring components of the station, microseismic sensors 3 are installed at the 1 / 3 and 2 / 3 positions of the height of the side wall block 4 of the second ring station. The installation method of the second ring station vault sensor is the same as that of the first ring. In the subsequent installation process of the prefabricated components, the installation method of the sensors on the odd rings is the same as that of the first ring, and the installation method of the sensors on the even rings is the same as that of the second ring. The assembly method is to assemble the prefabricated components in the order of the side wall block 4 of the station → the top plate of the station. After every 4 rings are assembled, the main body circumferential and longitudinal joints are grouting, and the middle plate and side wall joints are grouting. Every 8 rings are assembled as one cycle. For details, see Figure 6 .

[0042] Step 105, each time the structural components are assembled, the fertilizer tank of the current cycle is backfilled. The fertilizer tank backfilling is carried out in sections, and the height of each section is fixed. After the backfilling of the current cycle is completed, the next section of the cycle is assembled. After the next cycle is assembled, the section backfilling of the current cycle is carried out, and at the same time, another section of the previous cycle is backfilled. This process is repeated until the structure is formed into a ring and the fertilizer tank backfilling construction is completed. For details, see Figure 2 .

[0043] Step 106: After the structure is formed into a ring, the top plate is finally backfilled.

[0044] In this way, through the above-mentioned assembly method, multiple strain sensors and multiple microseismic sensors can be installed at multiple locations of the station body, and the monitoring indicators of the strain sensors and microseismic sensors can be extracted to obtain the amount of damage to the fertilizer tank and the amount of deformation of the components. The early warning range of the fertilizer tank damage can be obtained through the microseismic wave velocity, which effectively evaluates the quality of the fertilizer tank backfill and realizes the monitoring of the fertilizer tank backfill quality evaluation information. The following will be based on the assembly structure components to explain in detail the monitoring method of the fertilizer tank backfill quality evaluation information in the embodiment of the present application. Figure 7 As shown, the steps of the method include:

[0045] Step 701: obtaining strain information of the assembly structure component monitored by the strain sensor; wherein the strain information is used to characterize the deformation of the surface of the assembly structure component after the fertilizer tank is backfilled for a preset period of time;

[0046] It should be noted that the deformation in the embodiment of the present application is caused by the squeezing of the surrounding rock and the fertilizer trough in the station body.

[0047] Step 702: Acquire damage information of the manure trough of the open-cut prefabricated subway station monitored by microseismic sensors, and information on the propagation velocity of microseismic waves within the manure trough monitored by the microseismic sensors. The damage information is used to characterize the amount of damage to the manure trough backfill, and the velocity information is used to determine the warning range for manure trough damage.

[0048] In the embodiment of the present application, the amount of damage refers to the degree of damage to the fertilizer tank, specifically, it may refer to damage inside the fertilizer tank and damage on the surface of the fertilizer tank.

[0049] Step 703: monitor the backfill quality evaluation information of the fertilizer tank based on the rate information, strain information, and damage information.

[0050] It can be seen that in the embodiment of the present application, strain information and damage information can be obtained by means of strain sensors and microseismic sensors arranged on the assembly structure components, so that the deformation of the surface of the assembly structure components and the amount of damage to the fertilizer tank backfill can be determined. Combined with the rate information used to determine the early warning range of fertilizer tank damage, the backfill quality evaluation information of the fertilizer tank can be monitored to realize the monitoring of the backfill quality of the fertilizer tank, that is, monitoring can be carried out while construction is being carried out. For example, when damage occurs inside the fertilizer tank, remedial measures can be taken in time during the construction stage to stop the loss in time.

[0051] In an optional implementation of the embodiment of the present application, the method of obtaining the strain information of the assembly structure component monitored by the strain sensor involved in the above step 701 may further include:

[0052] Step 11, obtaining the strain value of the assembled structural component in each cycle monitored by the strain sensor, and determining the average strain value of the assembled structural component in N cycles based on the strain value;

[0053] Step 12: determining the standard deviation corresponding to the average strain value, and determining the deformation of the assembly structure component based on the standard deviation and the average strain value.

[0054] The fertilizer tank is not backfilled all at once during the backfilling process, but can be divided into several stages of cyclic backfilling. After each cyclic backfilling is completed, damage information can be monitored at least once, so m damage information can be obtained, specifically: ε1, ε2, ....ε m Therefore, for the above steps 11 and 12, in a specific example, they can be implemented by the following formula:

[0055] 1) First calculate the mean value μ of the surface strain value of the assembly component output by the strain sensor in the first few cycles ε :

[0056]

[0057] 2) Calculate the standard deviation δ of the output of the first few cycles 2 :

[0058]

[0059] 3) Perform normalization:

[0060]

[0061] Among them, ε approaches 0. ε x To describe the deformation level of the surface of the assembled structural components within a period of time after the fertilizer tank is backfilled, that is, the strain information.

[0062] In an optional implementation manner of the embodiment of the present application, the method of obtaining damage information of the fertilizer trough of the open-cut prefabricated subway station monitored by the microseismic sensor involved in the above step 702 may further include:

[0063] Step 21: obtaining a count of microseismic events outputted by the microseismic sensor during each cycle of the fertilizer tank backfill, and determining an average count of microseismic events during N cycles based on the count of microseismic events;

[0064] Step 22 determines the standard deviation corresponding to the average microseismic event count, and determines the damage amount of the fertilizer tank backfill based on the standard deviation and the average microseismic event count.

[0065] It should be noted that the microseismic sensor can monitor the corresponding microseismic monitoring parameters, wherein the microseismic monitoring parameters may include: the cumulative microseismic event count at a certain moment, the microseismic wave propagation speed, and the time when the sensor receives the microseismic wave. Therefore, in the embodiment of the present application, by extracting the cumulative microseismic event count β at a certain moment obtained by the microseismic sensor monitoring, m , the amount of damage inside the fertilizer tank can be described, and the cumulative microseismic event count-time curve relationship can be obtained to monitor the spatiotemporal changes of backfill damage inside the fertilizer tank. The slope k of the cumulative event count graph can also be used to provide early warning of fertilizer tank damage. Furthermore, in a specific example, the above steps 21 and 22 can be:

[0066] First, calculate the mean μ of the microseismic event counts output by the microseismic sensors for the first few cycles of fertilizer tank backfilling. β :

[0067]

[0068] Calculate the standard deviation δ of the output of the first few cycles 2 :

[0069]

[0070] Perform normalization:

[0071]

[0072] Among them, ε approaches 0, β x To describe the damage level of fertilizer tank backfill in the first few cycles, that is, the damage amount.

[0073] Furthermore, for the microseismic wave velocity a in the embodiment of the present application, a is defined as the velocity of the microseismic wave propagating inside the fertilizer tank to determine the conditions of crack initiation and expansion inside the fertilizer tank. x (%) increased to ε x +dε x(%), and the probability density of the number of microseismic events generated in this process is defined as f(ε x ), then:

[0074] f(ε x )=a / ε x +b

[0075] Among them, a is the microseismic wave velocity parameter, b is the test parameter;

[0076] Also available:

[0077] f(ε x )dε x =dN / N

[0078] Where N is the strain level of the microseismic sensor in the fertilizer tank from the initial strain level to the strain level of the component to ε x The total number of microseismic events at .

[0079] Combining the two equations, we have: N = cε x a exp(bε x ), we get: Where c is a constant.

[0080] When the strain level gradually increases, the damage amount gradually increases, and the microseismic wave velocity gradually decreases, thereby obtaining the relationship between the strain level, the damage amount of the fertilizer tank, and the microseismic wave velocity a, as shown in the following example: Figure 8 shown.

[0081] In an optional implementation of the embodiment of the present application, the method of determining the backfill quality evaluation information of the fertilizer tank based on the rate information, strain information and damage information involved in the above step 703 may further include:

[0082] Step 31, scoring and calculating the rate information, strain information, and damage information according to the rank sum ratio method to obtain a target score;

[0083] Step 32: determine the preset score value interval that the target score falls into, and determine the backfill quality evaluation information of the fertilizer tank according to the preset score value interval that the target score falls into, wherein different preset score value intervals correspond to different backfill quality evaluation information.

[0084] Furthermore, after monitoring the backfill quality evaluation information of the fertilizer tank based on the rate information, strain information, and damage information, the method of the embodiment of the present application further includes:

[0085] Step 41: When the target score falls within a first preset score value interval, determining the backfill quality evaluation information of the fertilizer tank as first backfill quality evaluation information;

[0086] Step 42: if the target score falls within the second preset score value interval, determining the backfill quality evaluation information of the fertilizer tank as the second backfill quality evaluation information;

[0087] Step 43: If the target score falls within the third preset score value interval, determine the backfill quality evaluation information of the fertilizer tank as the third backfill quality evaluation information, and strengthen support for the fertilizer tank corresponding to the location of the target sensor;

[0088] Among them, the damage degree corresponding to the first backfill quality evaluation information is lower than the damage degree corresponding to the second backfill quality evaluation information, and the damage degree corresponding to the second backfill quality evaluation information is lower than the damage degree corresponding to the third backfill quality evaluation information; the target sensor is at least one of multiple strain sensors, and / or the target sensor is at least one of multiple microseismic sensors.

[0089] For the above steps 31 and 32, as well as steps 41 and 42, in a specific example, the following can be achieved: using the rank sum ratio method (RSP) to calculate the strain level ε x , the fertilizer tank damage level βx, and the rate parameter a are comprehensively evaluated, and the internal damage of the fertilizer tank is evaluated based on the RSR score. For example, the RSR score obtained by the rank sum ratio method is divided into three intervals: (0.3, 0.5), (0.5, 0.7), and (0.7, 0.9), corresponding to three types of internal fertilizer tank damage.

[0090] Among them, when RSR∈(0.7, 0.9), the inside of the fertilizer tank is in good condition, damage signals begin to appear inside the fertilizer tank, and the damage inside the fertilizer tank is controllable and maintained at a low level.

[0091] When RSR∈(0.5, 0.7), the internal damage of the fertilizer tank increases. During this stage, the rate parameter a generally changes in a small range and remains within a certain range. However, the internal damage of the fertilizer tank continues to increase. At this time, the damage of the fertilizer tank needs to be closely monitored.

[0092] When RSR∈(0.3, 0.5), the interior of the fertilizer trough is severely damaged. At this time, the microseismic sensor detection signals are more frequent, the microseismic wave velocity a is greatly attenuated, and the interior of the fertilizer trough begins to be damaged on a large scale. At this time, relevant support measures need to be taken immediately.

[0093] By using the rank sum ratio method for comprehensive judgment, the quality of the fertilizer tank backfill can be intuitively judged. At the same time, the various indicators of the assembled components can be monitored by strain sensors and microseismic sensors to prevent dangerous accidents. In particular, during the segmented cyclic backfilling of the fertilizer tank, the quality of the fertilizer tank backfill is monitored each time the backfill reaches the preset height of the sensor. During the current cycle of fertilizer tank backfilling, the effect of the fertilizer tank backfilling in the previous cycle can be monitored at the same time. That is, during the entire construction period of the fertilizer tank backfilling, the quality of the fertilizer tank backfilling of each part can be accurately monitored, and early warnings can be given for dangerous parts. In addition, when the assembled subway station is put into use, the embodiment of the present application can be used to monitor the internal damage of the fertilizer tank, monitor the internal damage of the fertilizer tank and the surrounding pressure of the station. The microseismic sensor can accurately locate the location where the fertilizer tank is damaged, and when an early warning is issued, measures can be taken to support the damaged part.

[0094] In a specific application scenario, the overall scheme of the backfill quality evaluation method of the open-cut assembled station fertilizer trough in the embodiment of the present application can be found in Figure 9 As shown, it can be seen that since the existing prefabricated station construction does not monitor the quality of fertilizer trough backfill, and the fertilizer trough backfill construction phase lasts for a long time, this application can monitor the quality of fertilizer trough backfill during the construction phase of the fertilizer trough backfill, preventing damage to the inside of the fertilizer trough during the long construction period, which is conducive to timely warning and taking safety measures. Furthermore, in this application, microseismic sensors installed on the lining side wall blocks are used to apply microseismic technology to the detection of fertilizer trough backfill in prefabricated stations. The microseismic sensors monitor the damage parameters related to the inside of the fertilizer trough, and the damage rate a is obtained by combining the deformation of the components obtained by the strain sensor, thereby obtaining the warning range of fertilizer trough damage, which can more intuitively evaluate the safety status of the fertilizer trough.

[0095] Corresponding to the above Figure 7 , the present application provides a monitoring device for evaluating the quality of fertilizer tank backfilling, such as Figure 10 As shown, the device includes:

[0096] The first acquisition module 1002 is used to obtain strain information of the assembly structure component monitored by the strain sensor; wherein the strain information is used to represent the deformation of the surface of the assembly structure component after the fertilizer tank is backfilled for a preset period of time;

[0098] The monitoring module 1006 is used to monitor the backfill quality evaluation information of the fertilizer tank based on the rate information, strain information and damage information.
