Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of foundation pit monitoring, in particular to a deep foundation pit construction monitoring system and a monitoring method thereof. BACKGROUND

[0002] The deep foundation pit excavation method includes slope excavation, center island excavation, basin excavation and reverse construction method excavation. The foundation pit excavation site environment is usually complex, and the geological conditions and the surrounding environment hide various risk factors, which cannot be accurately predicted in the construction design, and appear with the construction excavation process. The foundation pit excavation is a process of unloading the excavation surface and the surrounding soil, and the soil has rheological properties. During the process of unloading the soil, the characteristics will cause the soil pressure imbalance between the inside and outside of the foundation pit, and finally cause the foundation pit bottom to rise or the foundation pit horizontal displacement.

[0003] As can be seen from the above, foundation pit monitoring is an important link in foundation pit engineering construction, which refers to various observation and analysis work on the changes of foundation pit soil properties, support structure displacement and surrounding environment conditions during foundation pit excavation and underground engineering construction, so as to adaptively adjust the construction scheme according to the above monitoring results. Specifically, the existing foundation pit monitoring method generally involves third-party monitoring personnel irregularly surveying foundation pit environmental data through sensors (such as water level meters, leveling instruments, etc.), and manually recording the above survey data for subsequent foundation pit environmental state analysis.

[0004] According to the above-mentioned technology, the human operation in the current foundation pit monitoring process is too much, the human cost of manual survey will increase with the increase of the size of the foundation pit to be excavated, and the survey efficiency will also decrease with the increase of the size of the foundation pit to be excavated, so it needs to be improved. SUMMARY

[0005] In order to solve the technical problems of large human cost and low survey efficiency in the existing foundation pit monitoring process, the present application provides a deep foundation pit construction monitoring system and a monitoring method thereof.

[0006] In the first aspect, the present application provides a deep foundation pit construction monitoring system, which adopts the following technical scheme:

[0007] A deep foundation pit construction monitoring system, comprising a monitoring module, an intelligent acquisition terminal and a cloud platform, the monitoring module being communicatively connected to the intelligent acquisition terminal, and the intelligent acquisition terminal being communicatively connected to the cloud platform;

[0008] The monitoring module is used for monitoring the environmental change data of the foundation pit, wherein the environmental change data at least includes water level data, inclination data and displacement data.

[0009] The intelligent acquisition terminal is used for acquiring the environmental change data and transmitting the environmental change data to the cloud platform.

[0010] The cloud platform is configured to acquire and store the environmental change data, and to issue an alert information when the environmental change data is abnormal, so that the construction personnel can learn the alert information.

[0011] By using the above technical solution, the environmental change data, such as water level data, vertical displacement data, horizontal displacement data, and inclination data, near the foundation pit is automatically monitored by the monitoring module. The environmental change data is acquired by the intelligent acquisition terminal, and is transmitted to the cloud platform. The cloud platform stores and processes the environmental change data, and automatically issues an alert information when the environmental change data is abnormal, so that the construction personnel can learn the alert information. The human resource consumption caused by human intervention is reduced, the automatic monitoring and the intelligent alert of data abnormality are realized, and the monitoring efficiency is improved.

[0012] Optionally, the deep foundation pit construction site is provided with a plurality of monitoring points, each of the monitoring points corresponds to at least one monitoring module, so as to monitor the environmental change data at the corresponding monitoring point.

[0013] The cloud platform further comprises a processing module configured to draw and display a curve graph of the environmental change data changing with time based on the acquisition time of the environmental change data; and to mark and display all the monitoring points and the monitoring results of each monitoring point in the form of a map based on the position information of the monitoring points corresponding to the environmental change data.

[0014] By using the above technical solution, the cloud platform provides a plurality of ways for displaying the environmental change data, such as displaying in the form of a curve graph or a map. The change of the environmental change data with time can be more intuitively learned through the curve graph, and the positions of the monitoring points and whether the corresponding monitoring points are abnormal can be more intuitively learned through the map. When there is an abnormality, the corresponding abnormal monitoring point can be more quickly located, so that subsequent abnormality investigation and maintenance work can be carried out.

[0015] Optionally, the cloud platform further comprises a display module configured to acquire a review instruction triggered by a user, to retrieve and display data corresponding to review content based on a keyword and the review content in the review instruction, and to take the keyword as an index. The review instruction comprises the keyword and the review content.

[0016] By using the above technical solution, the cloud platform further provides a function of centrally displaying the content that the user wants to review. The keyword and the review content that the user wants to review can be preselected, and then the review instruction can be triggered. At this time, the cloud platform can take the keyword in the review instruction as a search term, retrieve the data consistent with the review content from the stored data, and display the data.

[0017] Optionally, the intelligent acquisition terminal is configured to acquire the environmental change data based on a preset acquisition frequency; and the cloud platform comprises an adjustment module.

[0018] The adjustment module is configured to increase and update the acquisition frequency when a difference between the environmental change data and a preset alert threshold falls within a specified difference range; and the frequency adjustment module is further configured to determine a construction amount every specified time length, and increase and update the acquisition frequency if the current construction amount is greater than the construction amount of the previous specified time length.

[0019] By using the above technical solutions, the monitoring module can monitor the environmental change data in real time, the intelligent acquisition terminal can acquire the environmental change data monitored by the monitoring module according to the preset acquisition frequency, and transmit the environmental change data to the cloud platform, so as to reduce the data processing amount of the cloud platform and reduce the data processing burden. As for the acquisition frequency, it can be adjusted according to the actual situation. For example, when the environmental change data approaches the preset alert threshold, it indicates that the environmental change data fluctuates greatly and is likely to become abnormal data, and therefore the acquisition frequency needs to be increased. In addition, when the construction amount increases, the risk of foundation pit environmental accidents caused by the construction amount will also increase, and therefore the acquisition frequency needs to be increased.

[0020] Optionally, the deep foundation pit construction site is provided with a plurality of monitoring points, each monitoring point corresponds to at least one monitoring module, and each monitoring module is configured to monitor the environmental change data at the corresponding monitoring point.

[0021] The intelligent acquisition terminal is configured to acquire the environmental change data monitored by the monitoring module corresponding to the target monitoring point according to the preset acquisition frequency during the construction period of the target monitoring point.

[0022] By using the above technical solutions, the deep foundation pit in the construction period has a higher risk degree of displacement, deformation and other accidents than the deep foundation pit not in the construction period. Therefore, the intelligent acquisition terminal highlights the environmental monitoring of the deep foundation pit in the construction period, so as to strengthen the monitoring intensity and risk prevention strength during the construction period.

[0023] Optionally, the cloud platform further comprises a construction period determination module, the construction period determination module is configured to divide a monitoring area for each monitoring point, and is further configured to acquire the distribution of construction personnel and the power-on operation of construction equipment in each monitoring area in real time, and is further configured to determine a construction time of a target monitoring area when there is a construction personnel in the target monitoring area or when the corresponding time of the power-on operation of the construction equipment, wherein the construction period of the monitoring point is a set of construction times corresponding to the monitoring point.

[0024] By adopting the technical scheme, according to the number of monitoring points, a monitoring area is divided for each monitoring point, and once a construction personnel enters any monitoring area or there is a construction equipment in operation in the monitoring area, it indicates that the monitoring area and the corresponding monitoring point are in a construction period.

[0025] Optionally, the cloud platform further comprises a risk avoidance module, the risk avoidance module is configured to determine a monitoring area where abnormal environmental change data is located, a construction personnel in the corresponding monitoring area, and send a risk avoidance path to the construction personnel terminal when the abnormal environmental change data occurs, so that the construction personnel can move to a safe area along the risk avoidance path.

[0026] By adopting the technical scheme, when the environmental change data is abnormal, it indicates that there is a risk of an accident about to occur, and the existing technology generally only issues warning information that can be known by the construction personnel, but for the construction personnel still in the construction site, there is still a risk of injury due to not avoiding the risk in time. Therefore, the application sends a risk avoidance path to the construction personnel in the risk area when the warning is issued, so as to guide the construction personnel to move away from the risk position and move to a safe position.

[0027] Optionally, the intelligent acquisition terminal comprises a master acquisition terminal and a slave acquisition terminal; the master acquisition terminal and the slave acquisition terminal are respectively communicatively connected to the monitoring module, and the master acquisition terminal and the slave acquisition terminal are both configured to sequentially and alternately acquire the environmental change data collected by the monitoring module.

[0028] The cloud platform further comprises a fault determination module, the fault determination module is configured to acquire and calculate a first difference value of the environmental change data acquired by the master acquisition terminal and the slave acquisition terminal, and push maintenance information to the maintenance personnel terminal when the first difference value is greater than a preset difference threshold.

[0029] By adopting the technical scheme, the master acquisition terminal and the slave acquisition terminal acquire the environmental change data collected by the monitoring module in sequence, correspondingly, the acquisition time of the environmental change data acquired by the master acquisition terminal and the slave acquisition terminal is different and has a sequence, and by setting the two acquisition terminals to acquire the environmental change data respectively, the effect of mutual comparison can be achieved to avoid the situation that the acquired environmental change data is incorrect due to failure of the acquisition terminal or connection line, and if the first difference value of the environmental change data acquired by the master acquisition terminal and the slave acquisition terminal in sequence is greater than the preset difference threshold, the maintenance information is pushed to the maintenance personnel terminal.

[0030] Optionally, the fault determination module is further configured to increase the acquisition frequency when the first difference value is greater than the preset difference threshold.

[0031] By adopting the above technical solution, if the difference between the environmental change data obtained by the main acquisition terminal and the environmental change data immediately obtained by the slave acquisition terminal is greater than the preset difference threshold, then there may be two situations: situation 1 is equipment or line failure, and situation 2 is that the environmental change data fluctuates suddenly during this period. Therefore, in order to avoid missing the possibility of situation 2, the fault determination module of this application can further increase the acquisition frequency while pushing maintenance information, thereby achieving the effect of further improving the risk prevention.

[0032] Secondly, this application discloses a method for monitoring deep foundation pit construction, comprising the following steps:

[0033] The monitoring module monitors environmental change data during the construction of the foundation pit, wherein the environmental change data includes at least water level data, tilt data, and displacement data;

[0034] The intelligent data acquisition terminal acquires the environmental change data collected by the monitoring module and transmits the environmental change data to the cloud platform;

[0035] The cloud platform receives and stores the environmental change data, determines whether the environmental change data is abnormal, and issues a warning message when the environmental change data is abnormal, so that construction personnel can be informed of the warning message.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The monitoring module automatically monitors environmental change data near the foundation pit, such as water level data, vertical displacement data, horizontal displacement data, and tilt data. The intelligent acquisition terminal then acquires the above environmental change data and transmits it to the cloud platform. The cloud platform stores and processes the environmental change data and automatically determines whether the environmental change data is abnormal. When an anomaly occurs, it issues a warning message that can be known by construction personnel, reducing the manpower consumption caused by human intervention, realizing automated monitoring and intelligent judgment and warning of data anomalies, and improving monitoring efficiency.

[0038] 2. Furthermore, the cloud platform provides a variety of ways to display environmental change data, such as in the form of graphs or maps. Graphs can provide a more intuitive understanding of how environmental change data changes over time, while maps can provide a more intuitive understanding of the location of each monitoring point and whether the corresponding monitoring point is abnormal. This makes it easier to quickly locate the corresponding abnormal monitoring point when anomalies are found, so as to carry out subsequent anomaly investigation and maintenance work.

[0039] 3. Further, the cloud platform also provides a function of centralized display of the content that the user wants to review, and the function is used for pre-selecting a keyword and review content that the user wants to review, triggering a review instruction, at this time, the cloud platform can take out the data consistent with the review content from the stored data with the keyword in the review instruction as a search term, and display the data.

DETAILED DESCRIPTION

[0044] The following will be described in detail with reference to the drawings. Figures 1-2 The present application will be further described in detail.

[0045] The embodiments of the present application disclose a deep foundation pit construction monitoring system, which is suitable for real-time monitoring of the stability of surrounding adjacent buildings and auxiliary facilities in a foundation pit excavation stage, a support construction stage, an underground building construction stage and a completed stage, including underground water level monitoring, support stress monitoring and horizontal displacement monitoring, and undertakes the responsibilities of on-site monitoring data acquisition, review, summary, arrangement, analysis and data transmission, and alarms for data exceeding the warning limit, and provides reliable data support for design and construction.

[0046] Specifically, refer to Figure 1, the deep foundation pit construction monitoring system comprises a monitoring module 1, an intelligent acquisition terminal 2 and a cloud platform 3, wherein a plurality of monitoring points are preset on a deep foundation pit construction site, each monitoring point corresponds to the monitoring module 1, the monitoring module 1 is used for monitoring and collecting environmental change data of the foundation pit in real time, and the environmental change data can specifically include water level data, inclination data, vertical displacement data, horizontal displacement data, support shaft force data and the like; correspondingly, the monitoring module 1 can be a dual-axis inclinometer for detecting the horizontal displacement of the supporting slope, or a static leveling instrument for detecting the vertical displacement of the supporting slope, or a fixed inclinometer for detecting the deep horizontal displacement, or an immersion type water level gauge for detecting the water level, or a shaft force meter for detecting the support shaft force, or any combination of all the above instruments.

[0047] With reference to Figure 1 , the intelligent acquisition terminal 2 is communicatively connected to the monitoring module 1, and the intelligent acquisition terminal 2 is communicatively connected to the cloud platform 3, and the intelligent acquisition terminal 2 is used for transmitting the environmental change data collected by the monitoring module 1 to the cloud platform 3 according to a preset acquisition frequency. The intelligent acquisition terminal 2 specifically comprises a master acquisition terminal 21 and a slave acquisition terminal 22, and the master acquisition terminal 21 and the slave acquisition terminal 22 are both communicatively connected to all the monitoring modules 1, so as to acquire the environmental change data monitored and collected by the monitoring modules 1 according to the preset acquisition frequency, and the difference lies in that the master acquisition terminal 21 and the slave acquisition terminal 22 alternately acquire the environmental change data in sequence, the master acquisition terminal 21 acquires first, the slave acquisition terminal 22 acquires later, and then the acquisition is reciprocally alternated, and it should be noted that the master acquisition terminal 21 and the slave acquisition terminal 22 acquire the environmental change data corresponding to different monitoring and collecting times.

[0048] With reference to Figure 1 , a user can access the cloud platform 3 through a website or a mobile APP, and the cloud platform 3 is used for storing the environmental change data, displaying the environmental change data in different forms, and pushing a message to a communication terminal of a construction personnel or other personnel when the environmental change data is abnormal.

[0049] With reference to Figure 1 , specifically, the cloud platform 3 comprises a storage module 31, a processing module 32, a display module 33 and an early warning module 34; wherein the storage module 31 is used for acquiring and storing all the environmental change data transmitted by the intelligent acquisition terminal 2, and storing the environmental change data in the order of acquisition time, and can also store project information, engineering information, construction organization, construction personnel information, equipment information and the like corresponding to the environmental change data. The project information includes project name, project location and the like; the engineering information includes engineering type, warning information, on-site construction pictures and the like, and the equipment information includes monitoring sensors corresponding to each monitoring module 1, intelligent acquisition terminal 2 information, running state of each construction equipment and the like.

[0050] Referring to Figure 1 , the processing module 32 is configured to periodically (e.g., 7 days) retrieve the environmental change data from the storage module 31, and draw a curve graph of the retrieved environmental change data changing with the acquisition time as the horizontal coordinate, and display the curve graph.

[0051] Referring to Figure 1 , the processing module 32 is further configured to mark all monitoring point positions on a preset map, display the corresponding environmental change data at each monitoring point, and update the displayed environmental change data in real time; in addition, it should be noted that the intelligent collection terminal 2 pre-stores a correspondence table between the communication address of each monitoring module 1 and the corresponding monitoring point geographical position information, and accordingly, the intelligent collection terminal 2 will also attach the corresponding monitoring point geographical position information when transmitting the environmental change data to the cloud platform 3, so that the processing module 32 can update the environmental change data of the monitoring point according to the geographical position information.

[0052] Referring to Figure 1 , the display module 33 is configured to retrieve data consistent with the viewing content in the viewing instruction from the storage module 31 based on the viewing instruction triggered by the user, and display the data; specifically, when the user accesses the cloud platform 3, the cloud platform 3 can preset index buttons and index boxes on the preset display page, so as to trigger the viewing instruction and input the keywords, viewing content and display method; for example, the keyword is horizontal displacement data, the viewing content is the horizontal displacement data of xx project from March to April, and the display method is a curve graph.

[0053] Referring to Figure 1 , the early warning module 34 is configured to retrieve the environmental change data in the storage module 31 in real time, compare each environmental change data with a preset warning threshold, such as comparing the monitored horizontal displacement data with a preset horizontal displacement warning threshold, if the environmental change data is higher than the preset warning threshold, it is considered that the environmental change data is abnormal and in an abnormal state, if the environmental change data is lower than the preset warning threshold, but the difference between the two is less than a preset fixed difference, i.e., the environmental change data approaches the preset warning threshold, it means that the environmental change data is in a pre-warning state, if the environmental change data is lower than the preset warning threshold, and the difference between the two is greater than the fixed difference, it means that the environmental change data is in a normal state. The early warning module 34 is configured to generate and issue warning information when the environmental change data is abnormal, so that the construction personnel can obtain the warning information, wherein the form of issuing the warning information can be directly displayed on the access page, or the warning information can be sent to the intelligent terminal of the construction personnel; the specific content of the warning information can include the abnormal environmental change data and the corresponding monitoring point position information.

[0054] With reference to Figure 1 , the cloud platform 3 further comprises a hedge module 35, which is configured to determine the monitoring area where the abnormal environmental change data is located, the construction personnel in the corresponding monitoring area, and send a hedge path to the construction personnel terminal when the abnormal environmental change data occurs, so that the construction personnel can move to a safe area along the hedge path. Specifically, the hedge module 35 will divide the monitoring area for each monitoring point according to the overall size and position of the construction site, and the position of the preset monitoring point. For example, a circle center area with a monitoring point as the center and a specified length as the radius is determined as the monitoring area, and the detection areas of adjacent monitoring points can be tangential.

[0055] With reference to Figure 1 Before construction, a GPS locator can be installed on the safety helmet of each construction personnel, and the GPS locator is communicatively connected to the cloud platform 3, so that the hedge module 35 can know the distribution of construction personnel in each monitoring area. When the hedge module 35 knows that there is abnormal environmental change data, the hedge module 35 can determine the corresponding monitoring point position and the corresponding monitoring area, and then know the construction personnel in the monitoring area with risk through the GPS locator, and send a hedge path to the aforementioned construction personnel. The hedge path is a path that makes the construction personnel leave the aforementioned monitoring area, and the determination method of the hedge path can be to take the position of the construction personnel as the starting point, and combine the construction site terrain to make the shortest route for the construction personnel to leave the monitoring area with risk.

[0056] With reference to Figure 1 Optionally, if there are multiple monitoring areas with risk at the same time, the hedge path will prefer a path that does not pass through all the monitoring areas with risk. If it is inevitable to pass through the monitoring area with risk, all the monitoring areas with risk will be sorted in order from small to large risk, and the monitoring area with small risk will be preferred when determining the hedge path. The determination method of the risk size is the difference between the environmental change data of the monitoring point of the corresponding monitoring area and the preset warning threshold. The smaller the difference, the smaller the risk.

[0057] With reference to Figure 1 Since the intelligent acquisition terminal 2 acquires the environmental change data monitored by the monitoring module 1 based on the preset acquisition frequency, the cloud platform 3 further comprises an adjustment module 36, which is configured to adjust and update the acquisition frequency when any of the following conditions is met. The specific conditions are as follows:

[0058] 1. When the difference between the preset alert threshold value of the environmental change data reservation and the difference value falls within the specified difference value range, the collection frequency is increased and updated. Wherein, the specified difference value range can be the difference value interval corresponding to (0, fixed difference value), and this condition actually means that the environmental change data fluctuates and approaches the alert threshold value, or has exceeded the alert threshold value.

[0059] 2. The construction quantity is accelerated. Wherein, the construction personnel will upload the construction content of the day in the form of a log or other forms after completing the construction every day, and the construction content will mainly indicate the excavation depth, excavation area, etc. The adjustment module 36 will compare the construction quantity of the day compared with the previous day on a regular basis (such as every 24 hours), and the construction quantity can be represented by the further excavation depth and area of the day compared with the previous day. If the construction quantity is greater than the specified progress value (such as the specified depth, the specified area), it means that the construction quantity is accelerated.

[0060] Referring to Figure 1 When any of the above conditions is met, the current collection frequency is increased by a specified frequency value, that is, the collection frequency is increased, and the collection frequency can be up to 1 time / minute; otherwise, the collection frequency is reset to the preset initial frequency.

[0061] Referring to Figure 1 Optionally, since the processing of too much environmental change data will bring heavy computational burden to the system and occupy a large storage space, in order to reduce the above burden and free up storage space, the environmental change data monitored by the monitoring module 1 in real time can be selectively acquired; the selective acquisition is based on the following: since the deformation and displacement of the foundation pit are generally caused by construction, the environmental change data monitored by each monitoring module 1 at the construction period of the corresponding monitoring point can be acquired. Correspondingly, the intelligent collection terminal 2 is used to acquire the environmental change data monitored by the monitoring module 1 corresponding to the target monitoring point according to the preset collection frequency during the construction period of the target monitoring point, wherein the target monitoring point specifically refers to any monitoring point.

[0062] Referring to Figure 1 As for the determination method of the construction period, the cloud platform 3 of the application further comprises a construction period determination module 37, which is used to acquire the distribution of construction personnel and the running state of construction equipment in each monitoring area in real time, and is also used to determine that the target monitoring area is in the construction period when there is construction personnel in the target monitoring area or the construction equipment is powered on. The running state is that the target monitoring area is in the construction period; the construction period is the union of the stay time period of the construction personnel staying in the target detection area and the power-on running time period of the construction equipment in the target detection area.

[0063] Referring to Figure 2, the cloud platform 3 further comprises a fault determination module 38, the fault determination module 38 is used for obtaining and calculating the first difference value of the environment change data obtained by the master set acquisition terminal 21 and the slave set acquisition terminal 22, and when the first difference value is greater than a preset difference threshold, the acquisition frequency is increased, and the maintenance information is pushed to the maintenance personnel terminal. Specifically, if the first difference value is greater than the preset difference threshold, two situations are explained, situation 1 is that the master (or slave) set acquisition terminal is faulty, or the connection line connected with the monitoring module 1 is faulty, and situation 2 is that the environment change data suddenly mutates during this period. In order to facilitate the troubleshooting and avoidance of the above two situations, the fault determination module 38 will increase the acquisition frequency (increase the specified frequency value) at the same time, and push the maintenance information to the maintenance personnel terminal, so that the maintenance personnel can maintain and troubleshoot the master set acquisition terminal 21 and the slave set acquisition terminal 22 and their communication lines.

[0064] The working principle of the deep foundation pit construction monitoring system disclosed in the embodiment of the application is as follows: the monitoring points are planned in advance, the monitoring module 1 is installed at each monitoring point position, all monitoring modules 1 are simultaneously connected in communication with the intelligent acquisition terminal 2, and the intelligent acquisition terminal 2 is connected in wireless communication with the cloud platform 3. The environment change data at the corresponding monitoring point is monitored in real time by the monitoring module 1, including water level data, inclination data, support axial force data, horizontal displacement, vertical displacement data and the like. The above environment change data is obtained by the intelligent acquisition terminal 2 according to the preset acquisition frequency, and is transmitted to the cloud platform 3. The environment change data is stored by the cloud platform 3, and is processed to be displayed in the form of a chart or a map. At the same time, the cloud platform 3 sends warning information to the construction personnel terminal when the environment change data is abnormal, so as to finally realize automatic construction monitoring and intelligent judgment and early warning of abnormal risks.

[0068] S103, the cloud platform 3 receives and stores the environment change data, and determines whether the environment change data is abnormal, and sends warning information when the environment change data is abnormal, so that the construction personnel can know the warning information.

[0069] It should be noted that, in the present document, relational terms such as first and second and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

[0070] The above embodiments are merely used to illustrate the technical solutions of the present application, but not for limiting the scope of protection of the application.
