Description

Technical Field

[0001] The present invention relates to the field of submarine tunnel monitoring, and in particular to a method, a device and a storage medium for monitoring a broken zone of a submarine tunnel. Background Art

[0002] The construction of submarine tunnels takes safety and economy into consideration. The current technical means and construction technology cannot dig tunnels in deeper strata below the seabed, so the cover layer of submarine tunnels is often shallow. Fault fracture zones are common adverse geological phenomena in submarine tunnel construction. Because the seabed rock mass in the fracture zone is loose and broken, has low strength, good water-richness, high water permeability and easy deformation, it has significant differences in physical properties from the rock mass on both sides, and the submarine tunnel may continuously cross multiple fault fracture zones during construction. Drilling and blasting is the most common and economical construction method for submarine tunnels. The energy released in an instant by blasting and excavation is huge. Especially when the submarine tunnel is excavated through the fault fracture zone area, it is very easy to activate the fracture zone, causing adverse conditions such as super-seepage water gushing, large deformation of surrounding rocks and landslides, thereby affecting the stability of the tunnel and the safety of personnel. Once the tunnel and the fracture zone form a water flow channel, seawater will continue to flow back, which will cause irreversible losses. Therefore, the monitoring of the fracture zone of the submarine tunnel plays an important role in alleviating and reducing the risks of submarine tunnels.

[0003] The existing monitoring method for the broken zone of an undersea tunnel is usually to monitor the cracks and seepage pressure in the tunnel, while the monitoring of the seabed above the tunnel is usually ignored. When abnormal data is detected in the tunnel, it means that seawater has penetrated to the vicinity of the tunnel, and it is often too late to trace the source, and the best rescue period will be missed.

[0004] The existing monitoring method of the fracture zone of a submarine tunnel is to monitor the cracks and seepage pressure in the tunnel, resulting in a low early warning capability. Summary of the invention

[0036] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Figures 1 to 7 A method for monitoring a fracture zone of a submarine tunnel is shown, comprising the following steps:

[0038] S1: Multiple points are set up on the seabed of the broken zone and the flow rate of seawater at multiple points is monitored.

[0039] S2: Compare the flow velocities of multiple points. When the flow velocity of a certain point is 5% greater than the flow velocity of its adjacent point, the point is judged to be a water seepage point.

[0040] S3: Draw a curve of the relationship between flow velocity and time based on the relationship between the flow velocity monitored at each point and the time, and compare the flow velocity and time curves of the seepage point and the point farthest from the point. When the flow velocity difference at a certain moment is greater than 5% and the difference continues to expand, judge that moment as the starting point of the seepage.

[0041] For example, in an embodiment of the present invention, during the excavation of the submarine tunnel, it may pass through multiple longitudinal broken zones, and the excavation method of the submarine tunnel is usually through blasting. When the submarine tunnel is excavated through a broken zone, multiple points are arranged on the seabed at the top of the current broken zone, and the multiple points are arranged along the extension direction of the submarine tunnel to monitor whether the seabed above the broken zone has water seepage due to blasting. In this embodiment, the flow velocity information at each point can be transmitted through a signal and received by an external monitoring device. The spacing between each point is 0.5m. Due to the small spacing between the points, the flow velocity difference within 5% is usually regarded as an error caused by uneven ocean currents. When the flow velocity difference between different points is greater than 5%, it is judged that the point has a situation of seabed seepage, and the point is a water seepage point. Recording the location of the point is convenient for formulating subsequent response measures for the point. According to the relationship between the flow rate and time monitored at each point, a flow rate and time curve is drawn. Since seawater will continue to seep into the seepage point, the flow rate of the surrounding points will be affected by the wading point. At this time, the point farthest from the seepage point is least affected by the seepage point. The farthest point refers to the point with the farthest straight-line distance from the seepage point among all the arranged points, such as Figure 3 As shown in the figure, when the points are arranged in a mesh, point A is the seepage point, and point B is the farthest point. Therefore, the relationship curve between the flow velocity and time of the seepage point and the point farthest from the point is compared. When the flow velocity difference at a certain moment is greater than 5% and the difference continues to expand, the moment is judged to be the starting point of the seepage. During the monitoring process, the operator may not see the flow velocity information in time, so it is particularly important to judge the starting point of the seepage. When the seepage point and the starting point of the seepage are known, it is convenient to carry out remedial treatment of the seepage point in time, such as filling the seepage point to prevent the further spread of the seepage point. When the water flow velocity of a large number of points is abnormal, the communication function should be checked first to see if there is a fault. If there is no fault, go to the field to observe whether there is a water leakage. Compared with the traditional technology, which only monitors the cracks and seepage pressure in the submarine tunnel, in the embodiment of the present invention, multiple points are arranged on the seabed above the broken zone through which the submarine tunnel passes, and the flow velocity at multiple points is monitored to judge the seepage points, predict the breakage of the broken zone in advance, and buy sufficient time to repair the broken zone, thereby improving the early warning capability of the method.

[0042] The embodiment of the present invention provides a monitoring method, device and storage medium for the broken zone of an undersea tunnel. A plurality of points are arranged on the seabed of the broken zone, and the flow velocity of seawater at the plurality of points is monitored. The judgment is made according to the flow velocity of seawater. When the flow velocity at a point is 5% greater than the flow velocity at its adjacent point, the point is a water seepage point, that is, the point needs to be processed in time to prevent further collapse of the broken zone. The relationship between the flow velocity and time at the monitoring point is plotted, and the relationship curve between the flow velocity and time is compared with the relationship curve between the water seepage point and the point farthest from the point. When the flow velocity difference is greater than 5% at a certain time and continues to expand, the moment is judged to be the starting time of water seepage. According to the water seepage point and the starting time of water seepage, a remedial plan can be specified in advance and remedial measures can be taken to fill and repair the seabed above the broken zone, so as to prevent further collapse of the broken zone and cause backflow of seawater in the tunnel. The problem of low early warning capability in the prior art can be effectively solved.

[0043] Optionally, S1 includes a plurality of points arranged in a grid on the seabed of the broken zone.

[0044] Exemplarily, in an embodiment of the present invention, multiple points are arranged in a grid on the seabed of the broken zone. Compared with arranging the points in a straight line, the grid arrangement can cover a wider broken zone, so that specific water seepage points can be monitored more accurately, and it is also more convenient to repair the water seepage points later, thereby improving the accuracy of the method in identifying water seepage points.

[0045] Optionally, S3 includes comparing the relationship curve between flow velocity and time of the seepage point and its adjacent point, and if the curve trend of the adjacent point is similar to that of the seepage point and is distributed with a gradient offset, then determining that the adjacent point is a second seepage point.

[0046] Exemplarily, in an embodiment of the present invention, as time goes by, seawater will gradually flow in through the seepage point, causing the flow rate at the seepage point to gradually increase. Since the gap at the seepage point will be gradually enlarged by the pressure of seawater, the relationship curve between the flow rate and time at the seepage point will form a gradient offset distribution. By comparing the relationship curve between the flow rate and time of the seepage point and its adjacent point, if the curve trend of the adjacent point is similar to that of the seepage point and is distributed in a gradient offset, it means that the adjacent point is also about to be damaged. This point is called the second seepage point. After a period of time, the second seepage point may become a seepage point. By observing the second seepage point, the direction of the extension of the broken zone can be predicted, which further facilitates the formulation of subsequent plans for repairing the broken zone.

[0047] A monitoring device for a broken zone of an undersea tunnel, the device comprising: a data acquisition module 1, a first analysis module 2, and a second analysis module 3, wherein the data acquisition module 1 is used to collect and monitor flow velocity data of multiple different points, the first analysis module 2 is used to compare the flow velocities of multiple points, and when the flow velocity difference between a certain point and its adjacent points is greater than 5%, the point is judged to be a water seepage point, and the second analysis module 3 is used to draw a relationship curve between flow velocity and time according to the relationship between the flow velocity monitored at each point and time, and compare the relationship curve between flow velocity and time of the water seepage point and the point farthest from the point, and when the flow velocity difference is greater than 5% at a certain moment and the difference continues to expand, the moment is judged to be the starting time of water seepage.

[0048] Exemplarily, in an embodiment of the present invention, the flow velocity data of multiple points are collected by the data acquisition module 1, and the data signal is transmitted to the first analysis module 2 and the second analysis module 3. The flow velocities of multiple points are compared by the first analysis module 2. When the flow velocity of a certain point is greater than 5% compared with the flow velocity of its adjacent point, the point is judged to be a seepage point. Then, the second analysis module 3 draws a flow velocity and time relationship curve according to the relationship between the flow velocity monitored at each point and the time, and compares the flow velocity and time relationship curve of the seepage point and the point farthest from the point. When the flow velocity difference is greater than 5% at a certain moment and the difference continues to expand, the moment is judged to be the starting time of the seepage. In this way, the processing of the flow velocity data of multiple points and the judgment of the seepage point and the starting time of the seepage are completed, which is convenient for the subsequent formulation of corresponding plans to repair the seepage points.

[0049] Optionally, the data acquisition module 1 includes a water flow velocity meter 11 , and a plurality of water flow velocity meters 11 are arranged in a grid on the seabed of the broken zone. The water flow velocity meter 11 includes a fan blade 111 and a generator motor base 112 , and the fan blade 111 is installed on the generator motor base 112 .

[0050] Exemplarily, in an embodiment of the present invention, multiple points are arranged in a mesh, and the water flow velocity meter 11 is set at multiple points. The center of the fan blade 111 is connected to the shaft of the rotor of the generator motor base 112. The direction of the fan blade 111 is set according to the direction of the seawater flow, so that the seawater flow drives the fan blade 111 to rotate, driving the rotor of the generator motor base 112 to rotate and generate electricity. The water flow velocity meter 11 also has a built-in micrometer, and the power generation is monitored by the micrometer to calculate the seawater flow rate, so as to monitor the seawater flow rate at each point. A communication device can also be set on the water flow velocity meter 11 to communicate with external equipment to transmit the flow rate information of each water flow velocity meter 11.

[0051] Optionally, the data acquisition module 1 further includes a battery 12 and a wire 13 , and the battery 12 and the generator motor base 112 are connected via the wire 13 .

[0052] Exemplarily, in the embodiment of the present invention, the wire 13 is a wire with a communication function, which can transmit the flow rate information collected by each water flow meter 11. A flexible anti-corrosion layer 131 is wrapped around the outer periphery of the wire 13 to prevent the wire 13 from being corroded by seawater and causing a short circuit. The wire 13 and the water flow meters 11 at each point form a mesh structure, and a battery 12 is arranged in the middle of the mesh structure. The battery 12 is connected to each water flow meter 11 through a wire, so that the excess electric energy generated by the water flow meter 11 is stored by the battery 12. At the same time, a signal transmitting element can be installed on the battery 12. The battery 12 collects the flow rate data of each water flow meter 11 collected by the wire 13, and transmits it to the first analysis module 2 and the second analysis module 3 through the signal transmitting element, thereby completing the data transmission.

[0053] Optionally, the data acquisition module 1 also includes steel nails 14 and a magnetic device 15. The steel nails 14 are arranged in a mesh pattern on the seabed of the broken zone. The magnetic device 15 matches the steel nails 14. The wire 13 is wound around the steel nails 14, and the water flow meter 11 is set on the wire 13.

[0054] Exemplarily, in an embodiment of the present invention, the steel nails 14 are installed by the multifunctional mechanical arm of the underwater robot. The steel nails 14 are arranged on both sides of the water flow meter 11. By providing a magnetic suction device 15, it can be sucked onto the steel nails 14 for a firm connection, so that the wire 13 wrapped around the steel nails 14 is fixedly installed between two adjacent steel nails 14, so that the water flow meter 11 arranged on the wire 13 can also be firmly fixed at the point, ensuring that the entire data acquisition module 1 can be firmly fixed at a specific position, and will not move even in the case of strong currents, thereby ensuring monitoring accuracy and stability.

[0055] Optionally, the data acquisition module 1 further includes a pressure sensor 16 , and the pressure sensor 16 is disposed on the magnetic attraction device 15 .

[0056] Exemplarily, in an embodiment of the present invention, the pressure sensor 16 is connected to the signal transmitting element on the battery 12 through the wire 13. By setting the pressure sensor 16, the water pressure conditions at multiple different points can be monitored. Under normal circumstances, the water pressure is in a stable state. When the pressure sensor 16 detects that the water pressure changes, it means that the broken zone may be damaged. By setting the pressure sensor 16, the water flow velocity meter 11 can be assisted to make judgments on multiple water seepage points, thereby further improving the monitoring accuracy of the device.
