Description

Technical Field

[0001] This application relates to the field of tunnel construction technology, and in particular to a construction scheme and apparatus for opening up the working face of the main tunnel through a cross passage. Background Technology

[0002] Research on tunnel cross passages primarily focuses on engineering technology and safety, exploring the construction stability of tunnels and cross passages, tunnel excavation deformation patterns, and personnel evacuation under emergency conditions such as fires and earthquakes. This research includes parameter settings and measures for tunnel cross passages. Tunnel cross passages not only serve as emergency refuge facilities during project operation, bearing the heavy responsibility of personnel evacuation and rescue, but also play a crucial role in the early stages of construction by increasing the working face of the main tunnel and accelerating its excavation. In actual construction, due to resource and manpower constraints, the time reduction achieved by entering the main tunnel through different cross passages varies. However, few studies have taken a management perspective, aiming to minimize tunnel construction time, and utilizing optimization methods to provide quantitative, reference-based optimization schemes for cross passage selection in construction organization.

[0003] Research on cross passage construction management largely focuses on technology development, risk management, and the application of modern technologies such as BIM in the construction management process. Tunnel engineering faces complex geological and environmental conditions and numerous unforeseen circumstances, leading to a concentration of risk management research in construction management. Studies on cross passage construction management primarily focus on technology development and risk management, addressing the deformation impacts and disaster prevention during cross passage excavation to ensure the safety of construction personnel, overall construction stability, and reduced construction time. During tunnel construction, cross passages and other auxiliary tunnels can be used to access the main tunnel, increasing the working face, accelerating construction progress, and shortening the project duration. However, due to constraints such as cost and resources, the number of working faces within the tunnel cannot be increased indefinitely. Currently, research on schemes for opening the main tunnel working face at cross passages mainly involves scheme comparison, with little research conducted on optimizing schemes for opening the main tunnel working face at cross passages with the goal of minimizing the construction period. Summary of the Invention

[0004] In view of this, embodiments of this application provide a construction method and apparatus for opening up the working face of the main tunnel through a transverse passage, so as to eliminate or improve one or more defects existing in the prior art.

[0005] One aspect of this application provides a construction method for opening a working face for a main tunnel through a transverse passage, comprising:

[0006] Obtain the cross passage selection optimization scheme diagram corresponding to the current construction progress of the target tunnel. The cross passage selection optimization scheme diagram is used to represent the main tunnel construction rate and the pilot tunnel construction rate of the target tunnel with lines of different slopes. The horizontal axis of the cross passage selection optimization scheme diagram represents the construction time, the vertical axis represents the construction distance, and the identifiers of each cross passage are marked on the vertical axis starting from the origin.

[0007] From the cross passage selection optimization scheme diagram, select the work face switching point with the goal of minimizing the remaining construction period of the target tunnel;

[0008] In each of the transverse passages, a first switching transverse passage and a second switching transverse passage corresponding to the working face switching point are selected respectively, so as to generate a construction plan for opening the working face of the main tunnel through the transverse passages corresponding to the current construction progress of the target tunnel for the pilot tunnel construction team and multiple main tunnel construction teams.

[0009] In some embodiments of this application,

[0010] The cross passage selection optimization scheme diagram includes the main tunnel line and the horizontal guide line respectively emanating from the origin. Since the construction speed of the horizontal guide line is often faster than that of the main tunnel, the slope of the horizontal guide line is higher than that of the main tunnel line. The main tunnel line is used to represent the excavation plan progress of the main tunnel of the target tunnel, and the horizontal guide line is used to represent the excavation plan progress of the horizontal guide tunnel of the target tunnel.

[0011] The cross passage selection optimization scheme diagram also includes: horizontal auxiliary lines starting from the identifiers of each cross passage, the intersection points of each horizontal auxiliary line with the main tunnel line and the horizontal guide line, and vertical auxiliary lines starting from each intersection point, for selecting the work face switching point with the goal of minimizing the remaining construction period of the target tunnel.

[0012] In some embodiments of this application, the selection of the workface switching point from the cross passage selection optimization scheme diagram with the goal of minimizing the remaining construction period of the target tunnel includes:

[0013] Among the vertical auxiliary lines of the main tunnel line and the vertical auxiliary lines of the horizontal traverse line, determine a target vertical auxiliary line of the main tunnel line and a target vertical auxiliary line of the horizontal traverse line that are the shortest apart;

[0014] Draw a vertical line upwards from the intersection of the target vertical auxiliary line on the main tunnel line and the line on the main tunnel line.

[0015] The intersection of the vertical line and the horizontal traverse line is taken as a work face switching point with the goal of minimizing the remaining construction period of the target tunnel.

[0016] In some embodiments of this application, the step of using the intersection of the vertical line and the horizontal traverse line as a work face switching point with the goal of minimizing the remaining construction period of the target tunnel includes:

[0017] The segment of the perpendicular line located between the horizontal guide line and the main tunnel line is defined as the first perpendicular line segment.

[0018] The line segment located between the horizontal conductor and the main tunnel line in the target vertical auxiliary line of the horizontal conductor is defined as the second vertical line segment;

[0019] Determine whether the lengths of the first vertical segment and the second vertical segment both meet the preset safety distance constraints. If so, the intersection of the vertical line and the horizontal conductor is taken as a work face switching point with the goal of minimizing the remaining construction period of the target tunnel.

[0020] In some embodiments of this application, the step of selecting a first switching cross passage and a second switching cross passage corresponding to the working face switching point in each of the cross passages, in order to generate a construction plan for opening the working face of the main tunnel through the cross passages corresponding to the current construction progress of the target tunnel for the pilot tunnel construction team and multiple main tunnel construction teams, includes:

[0021] In the identification of each of the horizontal channels on the vertical axis of the horizontal channel selection optimization scheme diagram, the identification of the horizontal channel pointed to by the horizontal auxiliary line on the horizontal auxiliary line corresponding to the target vertical auxiliary line of the main tunnel line is used as the identification of the first switching horizontal channel corresponding to the working face switching point.

[0022] In addition, the horizontal channel to which the target vertical auxiliary line of the horizontal guide is pointed is identified by the horizontal auxiliary line on the horizontal guide, and is used as the identifier of the second switching horizontal channel corresponding to the work surface switching point.

[0023] Based on the markings of the first and second switching transverse passages, a construction plan is proposed for the pilot tunnel construction team and multiple main tunnel construction teams to open up the main tunnel working face through the transverse passages.

[0024] In some embodiments of this application, the construction plan for opening up the working face of the main tunnel through the cross passage based on the identifiers of the first and second switching cross passages includes:

[0025] Based on the identifiers of the first and second switching transverse passages, a first construction plan is generated for the first main tunnel construction team to excavate the main tunnel. This plan allows the first main tunnel construction team to switch from the first and second switching transverse passages, which have already been excavated by the pilot tunnel construction team (which started construction at the same time as the first main tunnel construction team), to the intersection of the first and second switching transverse passages in the main tunnel and continue excavating the main tunnel.

[0026] Based on the work face switching point, determine the start time of the second main tunnel construction team for excavating the main tunnel from the intersection of the main tunnel and the first switching cross passage, and the end time of excavation to the intersection of the main tunnel and the second switching cross passage, so as to generate a second construction plan corresponding to the second main tunnel construction team, so that the second main tunnel construction team starts excavating the main tunnel from the intersection of the main tunnel and the first switching cross passage at the start time;

[0027] Based on the first construction plan, the second construction plan, and the preset construction plan corresponding to the pilot tunnel construction team used for excavating the pilot tunnel, a construction plan is generated to open up the main tunnel working face through the cross passage corresponding to the current construction progress of the target tunnel.

[0028] In some embodiments of this application, obtaining the cross passage selection optimization scheme diagram corresponding to the current construction progress of the target tunnel includes:

[0029] Obtain the tunnel construction progress model corresponding to the current construction progress of the target tunnel and establish an objective function with the goal of minimizing the remaining construction period of the target tunnel; wherein, the tunnel construction progress model includes the main tunnel construction data, pilot tunnel construction data, cross passage construction data, construction team data, and safety distance constraints of the target tunnel; the cross passage construction data includes: the location, construction speed, and construction length of each cross passage planned to be excavated from the pilot tunnel towards the main tunnel;

[0030] Based on the tunnel construction progress model, a corresponding cross passage selection optimization scheme diagram is drawn.

[0031] The second aspect of this application provides a construction device for opening a working face for a main tunnel through a transverse passage, comprising:

[0032] The scheme diagram acquisition module is used to acquire the cross passage selection optimization scheme diagram corresponding to the current construction progress of the target tunnel. The cross passage selection optimization scheme diagram is used to represent the main tunnel construction rate and the pilot tunnel construction rate of the target tunnel with lines of different slopes. The horizontal axis of the cross passage selection optimization scheme diagram represents the construction time, the vertical axis represents the construction distance, and the vertical axis is marked with the identifiers of each cross passage excavated from the pilot tunnel to the main tunnel starting from the origin.

[0033] The switching point selection module is used to select a work face switching point from the cross passage selection optimization scheme diagram with the goal of minimizing the remaining construction period of the target tunnel;

[0034] The construction plan generation module is used to select the first switching cross passage and the second switching cross passage corresponding to the working face switching point in each of the cross passages, so as to generate a construction plan for the target tunnel to open up the working face through the cross passages according to the current construction progress of the target tunnel for the pilot tunnel construction team and multiple main tunnel construction teams.

[0035] A third aspect of this application provides an electronic device including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the construction method for the construction scheme of opening a working face through a transverse passage.

[0036] A fourth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the construction method for creating a working face for a main tunnel through a transverse passage.

[0037] The construction scheme method for opening the main tunnel working face through cross passages provided in this application involves obtaining a cross passage selection optimization scheme diagram corresponding to the current construction progress of the target tunnel. This diagram uses lines with different slopes to represent the main tunnel construction rate and the pilot tunnel construction rate of the target tunnel. The horizontal axis of the diagram represents construction time, and the vertical axis represents construction distance. Starting from the origin, each cross passage excavated from the pilot tunnel towards the main tunnel is marked on the vertical axis. A working face switching point is selected from the cross passage selection optimization scheme diagram with the shortest remaining construction period of the target tunnel as the objective. Within each cross passage, a specific cross passage is selected... The first and second switching transverse passages corresponding to the work face switching points are used to generate construction plans for opening the main tunnel working face through the transverse passages, corresponding to the current construction progress of the target tunnel, for the pilot tunnel construction team and multiple main tunnel construction teams. This can effectively realize the construction process of opening the main tunnel working face through the transverse passages, and can effectively improve the efficiency and reliability of the construction plan, thereby improving the effectiveness and reliability of the constructed construction plan. By selecting the optimal construction plan for opening the main tunnel working face through the transverse passages, the efficiency of tunnel construction can be effectively improved, and the idle work and downtime during the construction process can be effectively reduced, thus reducing the waste of resources.

[0050] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0051] In the following description, embodiments of the present application will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0052] To effectively improve the operational efficiency of opening the main tunnel working face through a cross passage in tunnel engineering, this application provides a construction method for opening the main tunnel working face through a cross passage. See [link to relevant documentation]. Figure 1The construction scheme construction method for opening the working face of the main tunnel through a transverse passage, which can be executed by the construction scheme construction device for opening the working face of the main tunnel through a transverse passage, specifically includes the following:

[0053] Step 100: Obtain the cross passage selection optimization scheme diagram corresponding to the current construction progress of the target tunnel. The cross passage selection optimization scheme diagram is used to represent the main tunnel construction rate and pilot tunnel construction rate of the target tunnel with lines of different slopes. The horizontal axis of the cross passage selection optimization scheme diagram represents the construction time, the vertical axis represents the construction distance, and the vertical axis is marked with the identifiers of each cross passage excavated from the pilot tunnel to the main tunnel starting from the origin.

[0054] In one or more embodiments of this application, the opening of the main tunnel working face through the transverse passages specifically refers to: during tunnel construction, in the pilot tunnel, excavating various transverse passages from the excavated section of the pilot tunnel to the unexcavated section of the main tunnel; in the main tunnel, excavation is carried out along the depth direction of the main tunnel; when the transverse passage excavated from the pilot tunnel reaches the main tunnel, the intersection of the transverse passage and the main tunnel can be used as the working face of the main tunnel (also referred to as the main tunnel working face). When the excavation along the depth direction of the main tunnel also reaches the above-mentioned intersection, the construction team can reach the pilot tunnel from the main tunnel working face along the transverse passage. They can also find the initial opening of other transverse passages in the pilot tunnel, and then reach the intersection of this transverse passage and the main tunnel again from this initial opening through other transverse passages, i.e., another main tunnel working face. In this way, the construction team can continue to excavate the main tunnel from this main tunnel working face, while the main tunnel section between this main tunnel working face and the previous main tunnel working face can be excavated by other construction teams to realize the handover between different construction teams and the switching of the main tunnel working face.

[0055] In step 100, the excavation schedule for the main tunnel of the target tunnel must at least include the correspondence between the excavation time and the excavation distance along the depth direction of the main tunnel; the excavation schedule for the excavation of each transverse passage from the pilot tunnel to the main tunnel of the target tunnel must at least include the correspondence between the excavation time and the total excavation distance (the sum of the lengths of each transverse passage excavated sequentially) of each transverse passage excavated sequentially from the already excavated pilot tunnel to the main tunnel.

[0056] It is understood that any slope diagram that can represent the excavation schedule data of the main tunnel of the target tunnel and the excavation schedule data of each cross passage excavated from the pilot tunnel towards the main tunnel with lines of different slopes, and that can reflect the correspondence between the excavation schedule data of the main tunnel of the target tunnel and the excavation schedule data of each cross passage excavated from the pilot tunnel towards the main tunnel, can be defined as the cross passage selection optimization scheme diagram mentioned in step 100 of this application.

[0057] For example, the cross passage selection optimization scheme diagram can be a two-dimensional coordinate diagram. This two-dimensional coordinate diagram can contain a straight line starting from the origin of the corresponding rectangular coordinate system to represent the excavation plan progress of the main tunnel of the target tunnel and a straight line to represent the excavation plan progress of each cross passage of the target tunnel from the pilot tunnel to the main tunnel.

[0058] It is understandable that, since the main tunnel is the main construction section of the tunnel, its excavation rate is necessarily lower than the rate of excavating the transverse passages from the pilot tunnel to the main tunnel. Therefore, in the transverse passage selection optimization scheme diagram, the slope of the line used to represent the excavation plan progress of the main tunnel of the target tunnel is definitely lower than the slope of the line used to represent the excavation plan progress of each transverse passage from the pilot tunnel to the main tunnel.

[0059] Step 200: Select a work face switching point from the cross passage selection optimization scheme diagram with the goal of minimizing the remaining construction period of the target tunnel.

[0060] It is understandable that the shortest remaining construction period for the target tunnel can specifically refer to the point where the difference between the main tunnel operation time and the cross passage operation time is the smallest, and the point where the cross passage intersection point has the smallest difference between the main tunnel operation time and the cross passage operation time is the work face switching point.

[0061] In one or more embodiments of this application, a working face switching point refers to a switching position used to enable a construction team excavating the main tunnel to switch from one main tunnel working face to another main tunnel working face based on a cross passage excavated by a construction team that has been used to excavate the cross passage.

[0062] Step 300: Select the first switching cross passage and the second switching cross passage corresponding to the working face switching point in each of the cross passages, so as to generate a construction plan for opening the working face of the main tunnel through the cross passages corresponding to the current construction progress of the target tunnel for the pilot tunnel construction team and multiple main tunnel construction teams.

[0063] Specifically, after the construction plan is generated, each construction team can, according to the plan, excavate the transverse passages from the initial opening at the intersection of the pilot tunnel and the main tunnel towards the main tunnel, excavating transverse passages H1 to H5. According to the construction plan, transverse passage H2 is the first switching transverse passage, and transverse passage H5 is the second switching transverse passage. At the same time, while excavating the transverse passages, another construction team excavates along the depth direction in the main tunnel. After reaching the first switching transverse passage corresponding to the working face switching point, the team enters the second switching transverse passage (transverse passage H5) through the pilot tunnel from the first switching transverse passage (transverse passage H2) to reach the intersection of the main tunnel and the second switching transverse passage. From this point, the working face of the main tunnel is opened, and excavation continues along the depth direction in the main tunnel. The area between the intersection of the first switching transverse passage (transverse passage H2) and the second switching transverse passage (transverse passage H5) and the main tunnel is filled by another construction team along the depth direction, so that this other construction team is responsible for filling the gaps in the main tunnel working face switching of the aforementioned other construction team.

[0064] As can be seen from the above description, the construction method for opening the main tunnel working face through a transverse passage provided in this application embodiment can effectively realize the construction process of the construction scheme for opening the main tunnel working face through a transverse passage, and can effectively improve the efficiency and reliability of the construction scheme for opening the main tunnel working face through a transverse passage, thereby improving the effectiveness and reliability of the constructed construction scheme; by selecting the optimal construction scheme for opening the main tunnel working face through a transverse passage, the efficiency of tunnel construction can be effectively improved, and the phenomena of idle work and downtime during the construction process can be effectively reduced, thus reducing the waste of resources.

[0065] To further improve the efficiency and accuracy of construction schemes for opening the main tunnel working face through a transverse passage, this application provides a method for constructing a construction scheme for opening the main tunnel working face through a transverse passage, see... Figure 2 In the construction scheme construction method for opening the main tunnel working face through the transverse passage, the horizontal axis of the transverse passage selection optimization scheme diagram represents the construction time (which can be abbreviated as: time), and the vertical axis represents the construction distance (which can be abbreviated as: distance). The vertical axis is marked sequentially from the origin 0 with the identifiers of each transverse passage, specifically transverse passage H1, transverse passage H2, transverse passage H3, transverse passage H4, etc., where i can be a positive integer greater than 3. Figure 2 In this context, i can be equal to 4; horizontal channels H4 are also sequentially set with horizontal channels H5, all the way up to horizontal channel Hm, where m is a positive integer greater than 5.

[0066] The cross passage selection optimization scheme diagram includes a main tunnel line TM and a horizontal guide line (also referred to as a horizontal guide tunnel line) TP emanating from the origin, and the slope of the horizontal guide line TP is higher than the slope of the main tunnel line TM. The main tunnel line TM is used to represent the excavation plan progress of the main tunnel of the target tunnel, and the horizontal guide line TP is used to represent the excavation plan progress of each cross passage excavated from the horizontal guide tunnel of the target tunnel towards the main tunnel.

[0067] For example, the time taken for the main tunnel line TM to reach the intersection of each transverse passage and the main tunnel can be recorded sequentially as: TM1, TM2, TM3, TM4. i To TM n Where i is a positive integer greater than 3; n is a positive integer greater than 4.

[0068] Furthermore, the time corresponding to the completion of each transverse channel by the horizontal conductor TP excavation can be sequentially recorded as: TP1, TP2, TP3, TP4. i (i is a positive integer greater than 3, TP) i It can be TP4) to TP n n is a positive integer greater than 4; in Figure 2 In the middle, TP3 and TP n There can also be TP5 in between, at which point TP n It is TP6.

[0069] In addition, the cross passage selection optimization scheme diagram also includes: horizontal auxiliary lines starting from the markers of each cross passage, the intersection points of each horizontal auxiliary line with the main tunnel line and the horizontal guide line, and vertical auxiliary lines starting from each intersection point, to select the work face switching point with the goal of minimizing the remaining construction period of the target tunnel. The horizontal and vertical auxiliary lines are both located in... Figure 2 The middle part is indicated by a dashed line.

[0070] To further improve the reliability and effectiveness of selecting the workface switching point with the shortest remaining construction period of the target tunnel from the cross passage selection optimization scheme diagram, a construction scheme construction method for opening the main tunnel workface through a cross passage is provided in this application embodiment. (See also...) Figure 3 Step 200 of the construction scheme for opening the working face of the main tunnel through the transverse passage specifically includes the following:

[0071] Step 210: Among the vertical auxiliary lines of the main tunnel line and the vertical auxiliary lines of the horizontal traverse line, determine a target vertical auxiliary line of the main tunnel line and a target vertical auxiliary line of the horizontal traverse line that are the shortest apart.

[0072] For example, in Figure 4In the middle, the time difference between the horizontal traverse time point TP5 and the main tunnel time point TM2 is the smallest, that is... Therefore, the vertical auxiliary line of the tunnel line corresponding to time point TP5 is a target vertical auxiliary line of the horizontal traverse; time point TM2 is a target vertical auxiliary line.

[0073] Step 220: Draw a vertical line upwards from the intersection of the target vertical auxiliary line of the main tunnel line and the line of the main tunnel line.

[0074] Step 230: The intersection of the vertical line and the horizontal traverse line is taken as a work face switching point with the goal of minimizing the remaining construction period of the target tunnel.

[0075] exist Figure 4 In the middle, draw a perpendicular line vertically upward from the target vertical auxiliary line of the main tunnel line corresponding to time point TM2. The intersection of this perpendicular line and the horizontal guide line is point A. Point A serves as a work face switching point with the goal of minimizing the remaining construction period of the target tunnel.

[0076] To further ensure the construction safety of opening the main tunnel working face through a transverse passage, in the construction scheme construction method for opening the main tunnel working face through a transverse passage provided in the embodiments of this application, see [link to relevant documentation]. Figure 5 Step 230 of the construction scheme for opening the working face of the main tunnel through the transverse passage specifically includes the following:

[0077] Step 231: Determine the segment of the perpendicular line located between the horizontal guide wire and the tunnel line as the first perpendicular line segment.

[0078] Step 232: Determine the line segment located between the horizontal conductor and the main tunnel line in the target vertical auxiliary line of the horizontal conductor as the second vertical line segment.

[0079] Step 233: Determine whether the lengths of the first perpendicular segment and the second perpendicular segment both meet the preset safety distance constraint conditions. If yes, proceed to step 234; otherwise, exclude the current work surface switching point and find a new one. The smallest point is used for calculation.

[0080] Step 234: The intersection of the vertical line and the horizontal guide line is taken as a work face switching point with the goal of minimizing the remaining construction period of the target tunnel.

[0081] To further improve the effectiveness and reliability of generating construction schemes for opening the main tunnel working face through a transverse passage, a method for constructing a construction scheme for opening the main tunnel working face through a transverse passage is provided in an embodiment of this application, see [link to relevant documentation]. Figure 3Step 300 in the construction scheme for opening the working face of the main tunnel through the transverse passage specifically includes the following:

[0082] Step 310: In the labels of each of the horizontal channels on the vertical axis of the horizontal channel selection optimization scheme diagram, the label of the horizontal channel pointed to by the target vertical auxiliary line of the main tunnel line corresponding to the horizontal auxiliary line on the main tunnel line is used as the label of the first switching horizontal channel corresponding to the working face switching point.

[0083] Step 320: The horizontal channel to which the target vertical auxiliary line of the horizontal guide is pointed is identified by the horizontal auxiliary line on the horizontal guide, and this is used as the identifier of the second switching horizontal channel corresponding to the work surface switching point.

[0084] Step 330: Based on the markings of the first and second switching transverse passages, a construction plan is developed for the pilot tunnel construction team and multiple main tunnel construction teams to open up the main tunnel working face through the transverse passages.

[0085] To further improve the effectiveness and reliability of generating construction schemes for opening the main tunnel working face through a transverse passage, a method for constructing a construction scheme for opening the main tunnel working face through a transverse passage is provided in an embodiment of this application, see [link to relevant documentation]. Figure 5 Step 330 of the construction scheme for opening the working face of the main tunnel through the transverse passage specifically includes the following:

[0086] Step 331: Based on the identifiers of the first switching transverse passage and the second switching transverse passage, generate a first construction plan corresponding to the first main tunnel construction team for excavating the main tunnel, so that when the first main tunnel construction team excavates to the intersection with the first switching transverse passage in the main tunnel, it switches from the first switching transverse passage and the second switching transverse passage that the pilot tunnel construction team, which started construction at the same time as the first main tunnel construction team, has already excavated, to the intersection with the second switching transverse passage in the main tunnel and continues to excavate the main tunnel.

[0087] Step 332: Determine the start time of the second main tunnel construction team for excavating the main tunnel from the intersection of the main tunnel and the first switching cross passage, and the end time of excavation to the intersection of the main tunnel and the second switching cross passage, based on the work face switching point, so as to generate a second construction plan corresponding to the second main tunnel construction team, so that the second main tunnel construction team can start excavating the main tunnel from the intersection of the main tunnel and the first switching cross passage at the start time.

[0088] Step 333: Based on the first construction plan, the second construction plan, and the preset construction plan corresponding to the pilot tunnel construction team used for excavating the pilot tunnel, generate a construction plan for opening the main tunnel working face through the cross passage corresponding to the current construction progress of the target tunnel.

[0089] To further assess the effectiveness and reliability of the cross passage selection optimization scheme diagram corresponding to the current construction progress of the target tunnel, a construction scheme construction method for opening up the main tunnel working face through a cross passage is provided in this application embodiment, see [link to relevant documentation]. Figure 3 Step 100 of the construction scheme for opening the working face of the main tunnel through the transverse passage specifically includes the following:

[0090] Step 110: Obtain the tunnel construction progress model corresponding to the current construction progress of the target tunnel and establish an objective function with the goal of minimizing the remaining construction period of the target tunnel; wherein, the tunnel construction progress model includes the main tunnel construction data, pilot tunnel construction data, cross passage construction data, construction team data and safety distance constraints of the target tunnel; the cross passage construction data includes: the location, construction speed and construction length of each cross passage planned to be excavated from the pilot tunnel towards the main tunnel.

[0091] It is understood that the main tunnel construction data includes: the location of the main tunnel, the current construction progress, the construction speed, and the length to be constructed; the pilot tunnel construction data includes: the location of the pilot tunnel, the current construction progress, the construction speed, and the length to be constructed; the cross passage construction data includes: the location, construction speed, and length to be constructed of each cross passage planned to be excavated from the pilot tunnel towards the main tunnel; and the construction team data includes: personnel information, number of people, and responsibilities of each construction team, etc.

[0092] Step 120: Draw the corresponding cross passage selection optimization scheme diagram based on the tunnel construction progress model.

[0093] From a software perspective, this application also provides a construction device for constructing a construction scheme for opening a working face through a transverse passage, which is part of the construction scheme construction method for opening a working face through a transverse passage. See [link to relevant documentation]. Figure 6 The construction scheme device for opening the working face of the main tunnel through the transverse passage specifically includes the following components:

[0094] The scheme diagram acquisition module 10 is used to acquire the cross passage selection optimization scheme diagram corresponding to the current construction progress of the target tunnel. The cross passage selection optimization scheme diagram is used to represent the main tunnel construction rate and pilot tunnel construction rate of the target tunnel with lines of different slopes. The horizontal axis of the cross passage selection optimization scheme diagram represents the construction time, the vertical axis represents the construction distance, and the vertical axis is marked with the identifiers of each cross passage excavated from the pilot tunnel to the main tunnel starting from the origin.

[0095] The switching point selection module 20 is used to select a work face switching point from the cross passage selection optimization scheme diagram with the goal of minimizing the remaining construction period of the target tunnel.

[0096] The construction plan generation module 30 is used to select the first switching cross passage and the second switching cross passage corresponding to the working face switching point in each of the cross passages, so as to generate a construction plan for the target tunnel to open up the working face of the main tunnel through the cross passages for the pilot tunnel construction team and multiple main tunnel construction teams, which is based on the current construction progress of the target tunnel.

[0097] The embodiment of the construction scheme construction device for opening the working face of the main tunnel through the transverse passage provided in this application can be used to execute the processing flow of the embodiment of the construction scheme construction method for opening the working face of the main tunnel through the transverse passage in the above embodiment. Its function will not be repeated here, but can be referred to the detailed description of the embodiment of the construction scheme construction method for opening the working face of the main tunnel through the transverse passage.

[0098] The construction scheme construction device for opening the working face of the main tunnel through the transverse passage can perform the construction of the construction scheme on a server. Alternatively, in another practical application, all operations can be completed on the client device. The choice can be made based on the processing power of the client device and the limitations of the user's usage scenario. This application does not impose any limitations on this. If all operations are completed on the client device, the client device may further include a processor for the specific processing of the construction scheme construction for opening the working face of the main tunnel through the transverse passage.

[0099] The aforementioned client device may have a communication module (i.e., a communication unit) that can communicate with a remote server to achieve data transmission with the server. The server may include a server on the task scheduling center side; in other implementation scenarios, it may also include a server on an intermediate platform, such as a server on a third-party server platform that has a communication link with the task scheduling center server. The server may include a single computer device, a server cluster consisting of multiple servers, or a distributed server structure.

[0100] The server and the client device can communicate using any suitable network protocol, including those not yet developed as of the date of this application. Such network protocols may include, for example, TCP / IP, UDP / IP, HTTP, HTTPS, etc. Furthermore, such network protocols may also include RPC (Remote Procedure Call Protocol) and REST (Representational State Transfer Protocol) protocols used on top of the aforementioned protocols.

[0101] As can be seen from the above description, the construction scheme construction device for opening the main tunnel working face through the transverse passage provided in this application embodiment can effectively realize the construction process of the construction scheme for opening the main tunnel working face through the transverse passage, and can effectively improve the efficiency and reliability of the construction scheme for opening the main tunnel working face through the transverse passage, thereby improving the effectiveness and reliability of the constructed construction scheme; by selecting the optimal construction scheme for opening the main tunnel working face through the transverse passage, the efficiency of tunnel construction can be effectively improved, and the idle work and downtime during the construction process can be effectively reduced, thus reducing the waste of resources.

[0102] To further illustrate this solution, this application also provides a specific application example of a construction scheme for opening the working face of the main tunnel through a transverse passage. On the one hand, selecting the scheme of opening the working face of the main tunnel through a transverse passage accelerates the construction progress; on the other hand, it reduces idle time and downtime during construction, thus reducing resource waste.

[0103] The construction method for opening the main tunnel working face through a transverse passage provided in this application example first selects a suitable transverse passage in the pilot tunnel during the design phase (the locations of each transverse passage are already determined in the design drawings), and opens an initial opening at the intersection with the pilot tunnel. Then, the transverse passage is excavated from the initial opening towards the main tunnel, and finally, the main tunnel working face is opened through this transverse passage. This method of selecting the transverse passage from the pilot tunnel to the main tunnel can accelerate the construction progress of the main tunnel by selecting a transverse passage from the excavated section of the pilot tunnel to the unexcavated section of the main tunnel. Specific details are as follows:

[0104] (I) Core Process of Construction Scheme for Opening the Working Face of the Main Tunnel from the Transverse Passage

[0105] (1) Establish a tunnel construction progress model. Determine the location, length, quantity, and construction speed of the main tunnel, pilot tunnel, and cross passages, as well as the number of scaffolding teams and related distance constraints. To minimize the construction period, the idle time between scaffolding teams should be minimized, i.e., the switching time between work faces and the handover time between construction teams should be minimized.

[0106]

[0107] Among them, let there be a total n A horizontal passage, For the construction of the pilot tunnel up to the first The time spent in each horizontal passage Construction of the main tunnel up to the first The time point at each horizontal passage.

[0108] (2) First, based on the construction progress, draw an optimization scheme diagram for the selection of cross passages. With construction time as the horizontal axis and tunneling progress (distance) as the vertical axis, the straight line TP represents the pilot tunnel, its slope being the pilot tunnel excavation speed, and the straight line TM represents the main tunnel, its slope being the main tunnel excavation speed. The distance from the starting point of each horizontal line's intersection with the vertical axis represents the distance between the location of each cross passage and the entrance of the main tunnel. The cross passage locations on the vertical axis are numbered H1, H2, H3…H… n express.

[0109] (3) Find the intersection point of the transverse passage where the time difference between the main tunnel operation and the horizontal guide tunnel excavation is the smallest, i.e. The point with the smallest value is used as the initial switching point for the working face at the intersection with the main tunnel (the initial opening at the intersection with the main tunnel).

[0110] (4) Draw a vertical line upwards from the initial working face switching point. After this vertical line intersects with the main tunnel and the horizontal pilot tunnel, it must be ensured that... The vertical distance is greater than the distance constraint between the working faces of the main tunnel. Here, the distance constraint is selected as l (based on construction experience, l is usually taken as 800~1500m). If the condition is met, the working face can be entered from this cross passage; if not, a new one must be searched. The smallest point is used for calculation.

[0111] (5) Repeat the above steps to find the horizontal channel for adjusting and switching all work surfaces.

[0112] (II) Examples of construction schemes for opening up the working face of the main tunnel in a transverse passage

[0113] The tunnel section has a total of n cross passages. The lengths of the main tunnel, pilot tunnel, and cross passages are as specified in the design drawings. The construction speed of the pilot tunnel is higher than that of the main tunnel. and The slope is the construction speed.

[0114] Limitation 1: Safe distance between the main tunnel and the pilot tunnel;

[0115] Limitation 2: There are currently 3 work teams. One team (scaffolding team 3) is responsible for the pilot tunnel construction, and the other two teams (scaffolding team 1 and scaffolding team 2) are responsible for the main tunnel construction in shifts.

[0116] (1) For the tunnel construction progress design model, the objective function is calculated. If the construction period is to be shortened to the greatest extent, the idle time between the scaffolding teams should be minimized, that is, the switching time between work surfaces and the handover time between construction teams should be minimized.

[0117]

[0118] Among them, let there be a total n A horizontal passage, For the construction of the pilot tunnel up to the first The time spent in each horizontal passage Construction of the main tunnel up to the first The time point at each horizontal passage.

[0119] (2) First, draw an optimization scheme diagram for the selection of cross passages based on the construction progress.

[0120] like Figure 2 As shown, the drawing method allows for intuitive and convenient optimization of the tunnel design. With construction time on the horizontal axis and tunneling progress (distance) on the vertical axis, the straight line TP represents the pilot tunnel, its slope representing the pilot tunnel excavation speed, and the straight line TM represents the main tunnel, its slope representing the main tunnel excavation speed. The distance from the starting point of each horizontal line's intersection with the vertical axis represents the distance between each cross passage and the main tunnel entrance. The cross passage locations are numbered H1, H2, H3…H on the vertical axis. n It indicates that there are a total of 3 rack teams.

[0121] (3) Find the intersection point of the cross passage with the smallest difference between the main tunnel operation time and the cross passage operation time, and use this point as the initial operation face switching point;

[0122] like Figure 4 As shown, the minimum time difference can be found. Therefore, the first working face to enter the main tunnel from the transverse passage should be transverse passage H2.

[0123] (4) Draw a vertical line upwards from the initial working face switching point. After this vertical line intersects with the main tunnel and the horizontal guide, the vertical distance must be greater than the safe distance between the working faces of the main tunnel. Here, the safe distance is selected as 1000m. If the condition is met, enter the main tunnel from this cross passage to carry out the working face; if not, find a new one. The smallest point is used for calculation.

[0124] like Figure 4 As shown, because the safe distance between the main tunnel working face and the new working face of the horizontal pilot tunnel entering the transverse passage must be considered to be 1000m (i.e., all switching points must meet the distance constraint), from TP 5 Draw a perpendicular line from point A to line B. TP and TMThe perpendicular distance between the intersecting points should be greater than or equal to 1000m. If the above requirements are met, the working face will be established from the transverse passage H2 into the main tunnel. That is, scaffolding team 1 is responsible for completing the work from the main tunnel entrance to the section of the main tunnel where the transverse passage H2 intersects with the main tunnel. Then, scaffolding team 1 should proceed with the subsequent working face from the intersection of the transverse passage H5 and the main tunnel. A line parallel to scaffolding team 1 should be drawn from point A, such as... Figure 4 As shown.

[0125] (5) Repeat the above steps to find the horizontal channel for adjusting and switching all work surfaces.

[0126] Following the previous steps, find the next one. The minimum point is the intersection of the main tunnel and the cross passage where the difference in working time between the main tunnel and the cross passage is minimized. This point is then used as the work face switching point. This process is repeated until the optimal solution is selected.

[0127] Among them, scaffolding team 2 is responsible for filling the gap when scaffolding team 1 switches to the main tunnel working face, and scaffolding team 3 is responsible for the construction of the pilot tunnel.

[0128] In summary, the application example of this application, through the design of a construction scheme for opening the main tunnel working face via a transverse passage, can effectively realize the construction process of such a scheme, and can effectively improve the efficiency and reliability of the construction process, thereby improving the effectiveness and reliability of the constructed scheme.
