Description

Real-time monitoring system for large caisson foundation construction based on remote wireless transmission technology

technical field

The invention relates to the technical field of caisson construction. More specifically, the present invention relates to a real-time monitoring system for large-scale caisson foundation construction based on remote wireless transmission technology.

Background technique

The caisson is a shaft-shaped structure. It excavates the soil in the well, relies on its own gravity to overcome the friction of the well wall and sinks to the design elevation, and then seals the bottom with concrete and fills the well hole to make it a bridge pier or other structures. Foundation.

The caisson construction monitoring refers to the process of collecting the data of the caisson itself and surrounding structures during the construction of the caisson. The current caisson construction monitoring is mostly carried out manually by the staff at the construction site when the construction progress is certain, and then the collected raw data is processed into results, but there are many shortcomings in this data collection method:

1. The workload of manual collection is large, and data processing is prone to errors.

Since caisson construction involves the collection of parameters such as the stress, water level, and disturbance of the bottom and wall of the caisson, and the slope rate of surrounding buildings, both the collection frequency and the number of collections are very large, and manual collection is adopted. Inefficient and very error-prone when processing data.

2. Only the data at the time of collection, the data in other time periods cannot be queried, and the continuous change of the data cannot be grasped.

As a result of manual collection, only the data at the time of collection can be consulted, and the data of other time periods needs to be searched from the archives, which is difficult to find in the first time, and the results of manual collection cannot be observed intuitively Continuous change of data.

3. Real-time monitoring and early warning cannot be realized.

Since there is a certain lag between manual collection and calculation of results, and the frequency of manual collection is not high, construction personnel cannot obtain monitoring results in real time, so they cannot give early warnings of possible conditions during construction.

4. The result display is not intuitive.

The existing calculation results are often in the form of Excel tables. The table data is relatively general and the operation is cumbersome. Both the input speed and the reading speed are relatively slow, and it is impossible to intuitively see the changes of the monitoring results from the Excel table.

The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

It should be noted that the experimental methods described in the following embodiments, unless otherwise specified, are conventional methods, and the reagents and materials, if not otherwise specified, can be obtained from commercial sources; in the description of the present invention, The terms "landscape", "portrait", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", The orientation or positional relationship indicated by "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the referred device or element must have Certain orientations, constructed and operative in certain orientations, therefore are not to be construed as limitations on the invention.

The current caisson construction monitoring is mostly carried out manually by the staff at the construction site when the construction progress is certain, and then the collected raw data is processed into results, but there are many shortcomings in this data collection method: 1. Manual collection work The amount is large, and the data processing is error-prone. 2. Only the data at the time of collection, the data of other time periods cannot be queried, and the continuous change of the data cannot be grasped. 3. Unable to realize real-time monitoring and early warning. 4. The result display is not intuitive.

In order to overcome the above-mentioned defects of the prior art, as shown in Figure 1, an embodiment of the present invention provides a real-time monitoring system for large-scale caisson foundation construction based on remote wireless transmission technology, including:

The data collection group includes the caisson attitude monitoring module, caisson deflection monitoring module, caisson stress monitoring module and caisson internal and external water level monitoring module, in which the caisson attitude monitoring module is used to monitor the three-dimensional coordinates of the caisson, and the caisson deflection monitoring module It is used to monitor the inclination of the caisson. The caisson stress monitoring module is used to monitor the concrete strain and steel strain of the caisson. The water level monitoring module inside and outside the caisson is used to monitor the height difference between the inside and outside of the caisson.

The server is connected to the data collection group through a wireless transmitter, and the server is used to store the monitoring values output by the data collection group in time series, and the monitoring values include the three-dimensional coordinates of the caisson, inclination, concrete strain, Reinforcement strain and water level difference inside and outside the caisson.

The client is connected in communication with the server, and the client is used to obtain the construction data table and alarm information according to the monitoring value.

For the caisson attitude monitoring module, this module is used to monitor the three-dimensional coordinates of the caisson. During the construction of the caisson, determining the construction work position is the first task that needs to be completed. The caisson attitude monitoring module collects the work of the caisson in real time. Whether the position has shifted is equivalent to monitoring the stability of the soil at the construction site. If the three-dimensional coordinates of the caisson change, it indicates that there is a problem with the stress of the soil. The construction personnel can know the next step through further judgment and analysis. Suspend the construction, strengthen the foundation, or continue the construction. Obviously, the role of the caisson attitude monitoring module is very important.

For the caisson disturbance monitoring module, this module is used to monitor the inclination of the caisson. When the inclination of the caisson is large, it may be due to the uneven hardness of the soil at the foot of the caisson blade and the compaction of the backfill soil around the caisson. Uneven and uneven excavation lead to great disparity in the height of the soil surface in the well or sand gushing in the well. At this time, it is necessary to control the caisson from tilting to the offset direction, and the tilt will also affect the monitoring data of the caisson posture monitoring module.

For the caisson stress monitoring module, this module is used to monitor the strain of the caisson concrete and steel bars. If the stress of a certain part of the caisson increases locally, it is likely that the shape of the part has changed sharply, such as fatigue When the caisson stress monitoring module detects a local increase in stress, the stress situation at the corresponding position can be investigated and analyzed early, and the phenomenon of local increase in stress can be eliminated.

For the caisson internal and external water level monitoring module, this module is used to monitor the internal and external water level of the caisson. Monitoring the internal and external water level of the caisson is very important for caisson construction. If the internal and external water level difference is too large (generally refers to more than two meters), it will The occurrence of quicksand flowing into the well will cause the caisson to tilt and increase the workload of mud suction. Therefore, by setting the water level monitoring module inside and outside the caisson, the water level difference inside and outside the caisson can be detected in time, and early warning of water level changes can be given in time.

For the server, it is used for performing analog-to-digital conversion on the analog signal monitoring value output by the data collection group to obtain a digital signal monitoring value. It should be noted that the controllability of analog signals is poor. With the development of electronic technology and the emergence of high-performance control cores, the controllability of signals is greatly enhanced, and very humanized human-computer interaction functions can be completed. But almost all the measured data in reality are analog, so if you want the computer to understand the data, you must digitize it. The monitoring value is saved through the server, which solves the problem that the process is too dependent on manual work and the data is prone to error and loss.

For the client, the client is the key to the real-time monitoring system of the large-scale caisson foundation construction based on the remote wireless transmission technology of the present invention. The client solves the unintuitive display of caisson construction control information by visualizing the digital signal monitoring value. , showing the problem of incomplete information. At the same time, the client also establishes an alarm mechanism. According to the monitoring value, when the warning value is exceeded, the system will automatically send out an alarm signal.

On the basis of the above-mentioned embodiments, the caisson posture monitoring module includes Beidou positioning sensors arranged at four corners of the caisson, and the Beidou positioning sensors are used to collect three-dimensional coordinates of the corner points. At present, the main tower foundation of large-scale road-rail dual-purpose bridges all adopts the caisson construction method. Steel caisson construction is affected by water flow, local scour of river bed, tide and tugboat collision, etc. It is prone to overturning, shaking, floating and sinking, etc., and may even cause safety accidents. Therefore, in the process of caisson floating, pre-implantation analysis, caisson implantation, caisson suction mud sinking, and high-level connection, it is necessary to monitor the real-time posture of the caisson, provide safety warnings, and ensure the safety of the construction and the caisson. Implantation precision. The Beidou positioning sensor can monitor the three-dimensional coordinates of the four corners of the caisson and the overall inclination and torsion of the caisson in real time.

It should be noted that the Beidou positioning sensor has the advantages of high positioning accuracy, short observation time, no need for direct vision between the base station and the rover station, simultaneous provision of three-dimensional coordinates, high degree of automation, all-weather operation and no weather influence.

On the basis of the above embodiments, the caisson deflection monitoring module includes static level instruments arranged at the corner points of the caisson, the midpoints of each side of the caisson and the center of the caisson. Deflection refers to the linear displacement of the rod axis in the direction perpendicular to the axis or the linear displacement of the middle surface of the plate and shell in the direction perpendicular to the middle surface when the force or non-uniform temperature changes. The static level is a precision instrument used to measure the relative settlement of each measuring point of the foundation and the building. In the embodiment of the present invention, the static level is used to obtain the relative coordinates of each monitoring point of the caisson and the midpoint and Center point deflection value.

In the actual monitoring process, the static level at a corner point of the caisson is selected as the reference point, and the real-time height difference value of other levels relative to the reference point can be obtained, so as to calculate the deflection value of each side and the center of the caisson, for example, Calculate the deflection value Δ of the midpoint of one side, and the elevation difference between the two ends and the midpoint of the side relative to the reference point is d ₁ , d ₂ , d ₃ respectively, then the deflection value of the midpoint of the side Δ=(d ₁ +d ₂ —2d ₃ )/2.

When an object is deformed due to external factors (force, humidity, temperature field changes, etc.), an internal force that interacts with each part of the object is generated, and the internal force per unit area is called stress. Stress is a vector. The component along the normal direction of the section is called normal stress, and the component along the tangential direction is called shear stress. On the basis of the above-mentioned embodiments, the caisson stress monitoring module includes stress monitor. Among them, earth pressure gauges are arranged at the bottom of the caisson and around the well wall; concrete and steel strain gauges are mainly arranged at the top and bottom of the caisson each time it sinks; steel plate strain gauges are arranged on the steel shell of the caisson. Structural features choose whether to arrange steel plate strain gauges; the layout of all measuring points should be reasonably arranged according to the caisson construction technology and theoretical simulation calculation results.

On the basis of the above-mentioned embodiments, the water level monitoring module inside and outside the caisson includes a laser liquid level gauge and a piezometer respectively arranged inside and outside the caisson. The piezometer is suitable for long-term buried in hydraulic structures or other concrete structures and soils to measure the seepage (pore) water pressure inside the structures or soils.

On the basis of the above-mentioned embodiments, the data collection group also includes an electric tower inclination monitoring module on the surrounding structures of the caisson, specifically, including four static levels installed on the electric tower for settlement observation, and then according to the relative Calculate the inclination rate of the tower by the height difference between the two sets of points. For example, the numbers of the two relative measuring points are 1 and 3, the distance between them is D, and the measured settlement at a certain moment is d ₁ and d ₂ respectively. The inclination rate of the tower is |d ₁ -d ₂ |/D.

During the construction of large-scale caissons, there are many monitoring items of concern, and a large number of sensors are arranged accordingly. The workload of traditional manual testing is very large, and it is impossible to monitor and display the working conditions of caissons in real time. A set of real-time monitoring system was developed using client technology to monitor the caisson informatized construction, and an informationized monitoring center was established on site to collect real-time information on caisson geometry, structural stress, water level inside and outside the caisson, and the settlement of surrounding structures After the data are processed by the system, the real-time and historical status information of the caisson is displayed intuitively through the platform. After the system evaluates the construction status, it gives an early warning for the exceeding limit value and reminds relevant personnel to formulate countermeasures.

In an optional embodiment, the client includes:

The position display module is used to draw the three-dimensional model and the panoramic model of the caisson, and according to the installation position of the data collection group, the coordinates corresponding to the installation position on the three-dimensional model and the panoramic model, display the data collection group and the digital signal monitoring value;

The data table display module is used to obtain the construction data table and/or data curve composed of the digital signal monitoring values in the time interval according to the input time interval;

The early warning module is used to set the alarm value of each monitoring item, and judge and display the alarm information according to the digital signal monitoring value and alarm value.

The location display module is specifically used for:

Use CAD software to draw the three-dimensional model of the caisson and the panoramic model of the wellhead (in which the panoramic model, after taking pictures of the wellhead from all angles through the actual high-definition camera, it is combined into a three-dimensional graphic for visual display), according to the position of the data collection group , add the data collection group to the 3D model and the panoramic model. For example, for the Beidou sensors in the caisson attitude monitoring module, according to the corner positions of these Beidou sensors, add the display components of the Beidou sensors on the 3D model. In this way When you need to know the monitoring data of a Beidou sensor, you can directly select the corner points on the 3D model to obtain the monitoring data of the Beidou sensor. , y-axis and torsion angle, therefore, after clicking the display component of the Beidou sensor, the display interface will be a schematic plan view of the location of the Beidou sensor, more specifically, a schematic diagram of the cross-section of the caisson.

The data table display module is specifically used for:

Receive the time interval and monitoring items selected by the user; for example, if the user wants to see the monitoring results of the embankment settlement from 00:00:00 on June 1, 2017 to 15:15:15 on June 2, 2017, then send the location The presentation module inputs the above time and monitoring items.

According to the time interval and monitoring items input by the user, the monitoring results of the monitoring items in the corresponding time interval are retrieved from the server, and the monitoring results are summarized into an Excel table according to the time sequence, which is convenient for subsequent export when necessary.

The early warning module is specifically used for:

Set the yellow warning value, orange warning value and red limit value of each monitoring item. For example, the yellow warning value of the tower inclination rate is 0.24%, the orange warning value is 0.32%, and the red limit value is 0.4%. If the slope rate of the current tower is 0.2%, no warning message will be issued; if the slope rate of the current tower is 0.3%, a yellow warning message will be sent; if the slope rate of the current tower is 0.35%, an orange alarm message will be sent ; If the current tower tilt rate reaches or exceeds 4%, a red alarm message will be issued. Since it is necessary to register before logging in to the client, according to the mobile phone number or email address used during registration, the early warning information or alarm information will be sent to the mobile phone number or email address at the time of registration in real time.

On the basis of the above-mentioned embodiments, the operating system of the client adopts window server 2008, the database adopts SQL server 2008, and is developed based on C# and Java script. After entering the account number and password to log in to the client, the client displays the monitoring interface of each monitoring module.

Figure 2 shows the monitoring interface of the caisson attitude monitoring module in a super-large bridge project on the Yangtze River. As can be seen from the figure, the client fully displays the caisson in three views: the front view, the top view and the left view of the 3D model In the 3D model, 4.3416 and 4.5270 in the direction of Yangzhou and 4.1727 and 4.3221 in the direction of Zhenjiang are the real-time elevation values of each corner point respectively. In the main view and left view, the inclination of the x-axis and y-axis can be clearly observed Both ratios are 0.0021, and it can be observed in the top view that the torsion angle of the caisson is -0.0747. The three-dimensional coordinates of the Beidou sensor in the caisson attitude monitoring module at each monitoring point. For example, at monitoring point 1, the x-axis coordinate of a certain Beidou sensor is 5892.1970, the y-axis coordinate is 35.3222, and the z-axis coordinate is 4.5270.

Figure 3 shows the interface diagram of the historical data curve of the caisson attitude. As shown in Figure 3, when the client obtains the data curve, it first needs to set the time unit of the query. In Figure 3, it is performed in units of hours Query, the present invention also supports query in minutes and days. After selecting the time unit for query, enter the query time period. In Figure 3, it is from 10:30:02 on April 26, 2017 to April 27, 2017 At 14:00:00 on the day, monitor the curve of the detection value of point 1 in the above time period. On the one hand, it includes the change curve tables of the x-axis, y-axis, and z-axis; on the other hand, it further obtains the change curve tables of the inclination rates of the x-axis, y-axis, and z-axis.

Figure 4 shows the monitoring interface of the caisson deflection monitoring module. As can be seen from Figure 4, the client intuitively displays the real-time deflection values of the midpoints and central positions of the top surface of the caisson through the top view of the three-dimensional model: the central point deflection ( Along the bridge direction) -4.7mm; center point deflection (along the bridge direction) 6.85mm; upstream long side midpoint deflection -1.15mm; downstream long side midpoint deflection -31.30mm; Zhenjiang side short side deflection 2.80mm ; Short side deflection of Yangzhou side -12.15mm. At the same time, the real-time data curve on the right shows the deflection change trend in the latest period. The inquiry method of deflection historical data and curve is basically the same as that of caisson attitude, so it will not be repeated here.

Figure 5 shows the monitoring interface of the caisson stress monitoring module. As can be seen from Figure 5, the client directly displays the location and sensor information of the caisson stress monitoring points through the panoramic model, and the real-time curve column on the right side of the interface shows the latest The stress change curve of time period. In Figure 5, first select the number of caisson layers, and then click the hole position you want to view. Figure 5 shows that the stress measurement point in the No. 18 well hole of the first caisson layer is GB8, and the real-time data curve on the right shows that , the data of GB8 is relatively stable during the time period from 11:16 to 13:43.

Figure 6 shows the interface diagram of the caisson stress history data curve. Due to the large number of stress measurement points, it cannot be displayed by a display method similar to caisson posture or caisson deflection. The display of stress history data combines the method of querying real-time stress data and caisson posture historical data, that is, by querying stress measuring points, first find the measuring points you want to query, and then select the time unit and time period to display the data curve or export the data sheet. In Figure 6, the unit of time is hours, during the time period from 9:30:02 on April 25, 2017 to 10:30:02 on April 27, 2017, the stress measuring point FHN1-7 of the No. 4 wellbore of the first layer historical data curve.

Figure 7 shows the interface diagram of the historical data curve of the slope rate of the surrounding structures of the caisson - the electric tower. As shown in Figure 7, the client also needs to set the time unit and query time period when displaying the slope rate of the electric tower , the difference is that when displaying the change of the inclination rate of the tower, since there are multiple monitoring points arranged on the tower, the monitoring points are numbered at the same time, and the number range of the monitoring points is input on the client to obtain the monitoring points in different Between the monitoring points and on the direction, the change of the slope rate, for example, Fig. 7 shows the slope rate change in the direction of the monitoring point No. 1 to No. 3 and the slope rate change in the direction of the monitoring point No. 2 to No. 4, At the same time, for each monitoring point, it is also possible to display the height changes monitored by the monitoring point itself at different times. Figure 7 shows the height changes of monitoring points 1-4 relative to March 25, 2017 .

(1) Data collection: Compared with the traditional manual collection method, the automatic real-time collection method adopted in the present invention realizes all-weather data collection, and greatly improves collection efficiency and accuracy.

(2) Data transmission, storage and processing: the existing monitoring method still adopts manual input and data processing, and the process is cumbersome and procrastinating; in the present invention, the sensor data is directly transmitted to the server by wireless, and is automatically processed while storing, The whole process is done in one go, which improves the efficiency of transmission and processing.
