[0042] Step S33, determining the installation range of the reinforcing device according to the judgment result.

[0043] It can be understood that in the step S33, steps S331 and S332 are further included, which are specifically:

[0044] Step S331, when the judgment result is that there is an overlapping part in the planar projection of the existing tunnel and the adjacent engineering, a first extension line is extended to both sides of the existing tunnel with the midpoint of the overlapping part of the planar projection of the existing tunnel and the adjacent engineering as the center, the distance between the segment on the existing tunnel and the first extension line is calculated to obtain the first deviation value information of the segment, and it is judged whether the first deviation value of each segment meets the safety requirement, wherein the last ring segment of the segment meeting the safety requirement is taken as the reinforcing boundary;

[0045] Step S332, when the judgment result is that there is no overlapping part in the planar projection of the existing tunnel and the adjacent engineering, a second extension line is extended to both sides of the existing tunnel with the point closest to the perpendicular distance between the planar projection of the adjacent engineering and the existing tunnel as the center, the center is located on the planar projection of the adjacent engineering, the distance between the segment on the existing tunnel and the second extension line is calculated to obtain the second deviation value information of the segment, and it is judged whether the second deviation value of each segment meets the safety requirement, wherein the last ring segment of the segment meeting the safety requirement is taken as the reinforcing boundary.

[0047] In step S4, the installation angle is determined according to the second information, and third information is obtained.

[0048] It can be understood that in step S4, steps S41, S42, S43 and S44 are further included, which are specifically:

[0049] In step S41, the center point of the approaching engineering is determined according to the position information of the approaching engineering.

[0051] In step S42, the center point of the existing tunnel is determined according to the position information of the existing tunnel.

[0052] In this step, the position of the center point can be determined according to the position of the existing tunnel 2.

[0053] In step S43, the center point of the approaching engineering and the center point of the existing tunnel are connected, and the included angle between the line connecting the center point of the approaching engineering and the center point of the existing tunnel and the horizontal line is determined, and the angle information is obtained.

[0055] In step S44, the installation angle is calculated according to the angle information.

[0056] In this step, the installation angle θ can be calculated according to the angle information α, which is specifically:

[0057]

[0058] According to the above formula, the installation angle θ can be calculated according to the angle information α, and after the installation angle θ is determined, the balance steel plate 3 can be installed on the segment of the existing tunnel.​

[0059] Step S5, after installing the reinforcement device according to the third information, monitoring in real time to determine whether the reinforcement device needs to be replaced.

[0060] In this step, in some special cases, the deformation of the soil may be too severe, causing excessive force on the balance steel plate, leading to plastic deformation of the rigid joint node, and cracking or even crushing of the outer concrete on the balance steel plate, which not only causes the balance steel plate to lose its intended effect, but also damages the waterproof performance of the tunnel. Therefore, by monitoring the balance steel plate connection node in real time, the balance steel plate can be effectively replaced in real time to avoid such problems.

[0063] In this step, the stress control information is specifically:

[0064]

[0065] In the above formula, σ i is the measured stress value of the i-th anchor bolt screw on the outermost row on the tensile side of the anchor when visible cracks appear in the balance steel plate outer concrete, n is the number of anchor bolts on the outermost row on the tensile side of the anchor along the longitudinal direction of the tunnel, σ max and σ min respectively represent the maximum and minimum values of the measured stress value of the anchor bolt screw on the outermost row on the tensile side of the anchor when visible cracks appear in the balance steel plate outer concrete.

[0066] Step S52, calculating according to the tensile stress value information to obtain a calculation result;

[0067] In this step, the tensile stress value of the outermost row of anchor bolt screws on the tensile side is calculated according to the real-time monitoring and collection of the stress sensor, and the average tensile stress value of the outermost row of anchor bolt screws on the tensile side is obtained. Calculation result.

[0068] Step S53, comparing the calculation result with the stress control information to determine whether the reinforcement device needs to be replaced.

[0069] It can be understood that the step S53 further comprises a step S531, a step S532, a step S533 and a step S534, which are specifically:

[0070] The step S531 calculates the first stress threshold information and the second stress threshold information according to the stress control information, wherein the first stress threshold information is 0.7 times of the stress control information, and the second stress threshold information is 0.9 times of the stress control information.

[0071] In this step, it is assumed that the stress control information is The first stress threshold information is The second stress threshold information is

[0072] The step S532 judges whether the calculation result is greater than the first stress threshold information and less than the second stress threshold information, and if yes, enters the secondary early warning state.

[0073] In this step, it is judged whether the calculation result is greater than the first stress threshold information and less than the second stress threshold information, which is specifically:

[0074]

[0075] In the above formula, σ i测 is the measured stress value of the i th anchor rod on the outermost row of the anchor rod on the tension side collected by the sensor in real time, σ max and σ min respectively represent the maximum value and the minimum value of the measured stress value of the anchor rod on the outermost row of the anchor rod on the tension side collected in real time, and n is the number of the anchor rod on the outermost row of the anchor rod on the tension side along the longitudinal direction of the tunnel. It should be noted that the monitoring frequency should be not less than 2 times / day during the approach engineering construction process, and should be not less than 1 time / day after the approach engineering construction is completed. When entering the secondary early warning state, the monitoring frequency should be not less than 1 time / 2 hours.

[0076] The step S533 judges whether the calculation result is greater than the second stress threshold information and less than the stress control information, and if yes, enters the primary early warning state.

[0077] In this step, it is judged whether the calculation result is greater than the second stress threshold information and less than the stress control information, which is specifically:

[0078]

[0079] It should be noted that when entering the primary early warning state, the monitoring frequency should be not less than 1 time / hour.

[0080] Step S534: Determine whether the calculated result is greater than the stress control information. If it is greater, the nearby project will stop construction and the existing tunnel will be replaced with a reinforcement device.

[0081] In this step, when the calculated result exceeds the stress control information, the nearby project needs to stop construction and the existing tunnel reinforcement device needs to be replaced. The specific process for replacing the balance steel plate is as follows: during unloading, first unscrew the chemical anchor nuts, then remove the connecting weld and ribs between the inner steel plate and the balance steel plate, remove the inner steel plate, use equipment to pull the balance steel plate into the tunnel, and then use equipment to push the new prefabricated balance steel plate out horizontally.
