Description

Technical Field

[0002] Mechanized construction of mountain tunnels mainly includes excavation of primary support, invert, secondary lining and ancillary projects. The efficiency of the primary support cycle determines the efficiency of tunnel construction and plays a leading role. According to different surrounding rock levels, different mechanized equipment will be used in the excavation and primary support cycle of fully mechanized construction tunnels, mainly advanced drilling rigs, rock drilling rigs, loaders, excavators, dump trucks, arch frame trolleys, wet spraying trolleys, anchor trolleys, etc., which are divided into super-excavation exploration process, measurement process, advanced support process, excavation and drilling process, slag removal process, primary spraying process, arch erection process, re-spraying process, and anchor process.

[0003] Due to the limited space on the face and the sequence requirements of the tunnel construction process, the operating equipment between each process is carried out in turn, and the process connection is difficult. One of the goals pursued by tunnel construction management is to achieve "zero delay" between processes through reasonable deployment. At present, the connection of each process in the excavation initial support cycle basically relies on the command of on-site management personnel, and there is uncertainty in the connection of processes. The management of process connection is not compact and transparent. At the same time, the statistics of the construction efficiency of each process basically rely on manual reporting, and the efficiency data is not objective and the statistics are not timely. According to statistics, under the existing management model, the management of each process in the excavation initial support cycle is more disconnected, and the process connection time accounts for 10% to 20% of the total cycle time, and some reach more than 30%.

Description of the Drawings

[0036] Figure 1 is the process discrimination flowchart of the present invention;

[0037] Figure 2 is the cycle plan formulation flowchart of the present invention;

[0038] Figure 3 is the efficiency statistics table of the embodiment of the present invention. Detailed Embodiment

[0039] The following will further elaborate on the present invention in conjunction with the drawings and specific embodiments.

[0040] The specific solution of this embodiment is as follows: Before automatically discriminating the cycle process, a wireless transmission network and a positioning system need to be built in the tunnel to collect the positioning data of the equipment types corresponding to each process in the tunnel.

[0041] Relevant staff need to establish a database in advance. The database includes the cycle plans, processes, equipment types corresponding to the processes, and the planned start time and planned completion time of the cycle plans and processes for excavation and initial support of different tunnel surrounding rock levels. The cycle plan is the technology adopted for excavation and initial support of different tunnel surrounding rock levels, and the technology consists of multiple processes;

[0042] The steps for establishing the database include:

[0043] 1. Integrate the processes required for excavation and initial support of different tunnel surrounding rock levels and the equipment corresponding to the processes, and enter them into the database, as shown in Table 1;

[0044] Table 1 Database of tunnel mechanization processes and operating equipment

[0045]

[0046]

[0047] 2. Formulate a cycle plan template for the process: For different surrounding rocks and different sections, when the construction method is certain, the steps of the mechanized construction process of the tunnel are basically determined. Taking a tunnel with Grade IV surrounding rock as an example, the process plan template is as shown in Table 2;

[0048] Table 2 Process cycle plan template for Class IV surrounding rock

[0049]

[0050]

[0051] The above fourteen processes are all the processes that may be used for Grade IV surrounding rock of a tunnel. For example, the advanced exploration process requires the use of a multi-functional drilling rig. This process is mainly required for unfavorable geological conditions such as water-rich weak fault fracture zone, water-rich karst development zone, coal seam gas development zone, etc. in front of the heading face. Therefore, it is necessary to select according to the construction drawings and actual geological conditions on site. The processes selected as needed according to the actual geological conditions are non-essential processes, and other processes not noted are necessary processes.

[0052] Since the actual process execution may be different from the process in the cycle plan, large equipment is used as the key control process for process execution. The equipment corresponding to the key control process is the key equipment. The key equipment is manually pre-set as the setting equipment before starting the operation. The setting equipment includes a multi-functional drilling rig, a rock drilling trolley, a wet shotcreting trolley, an arch trolley, a multi-functional trolley, and an anchor trolley.

[0053] 3. Cycle plan formulation: According to the actual situation on site, the staff will list the plans in the cycle dimension and formulate the initial excavation cycle plan. Except for the first cycle plan, the other cycle plans use the completion time of the previous cycle plan as the cycle start time to achieve the rapid formulation of process plans and ensure the comparability of each cycle plan with the actual operation. After the cycle plan is completed, the corresponding plan and the processes contained are in the unstarted state. During the execution of the cycle plan, the non-essential processes contained in the subsequent cycle plan can be increased or decreased in real time according to the on-site construction situation.

[0054] like Figure 2 As shown in the figure, the specific steps of cycle planning are:

[0055] Determine whether it is the first cycle plan compiled;

[0056] If it is the first cycle plan, record the actual start time of the cycle plan. If it is not the first cycle plan, determine whether the status of the previous cycle plan of the currently prepared cycle plan is "completed". If the status of the previous cycle plan is "completed", load the actual completion time of the previous cycle plan as the start time of this cycle plan. If the status of the previous cycle plan is not "completed", load the planned completion time of the previous cycle plan as the start time of this cycle plan.

[0057] Select the corresponding cycle plan template according to the surrounding rock grade as the currently prepared cycle plan, and correct the currently prepared cycle plan according to the actual operation steps on site and the operation equipment corresponding to the processes.

[0058] Calculate the planned start time and planned completion time of each process and the completion time of the currently prepared cycle plan.

[0059] Update the status of the currently prepared cycle plan to "not started", and update the status of all processes in this cycle plan to "not started".

[0060] After the above preparations are completed, the automatic process discrimination can be started. For example, Figure 1 As shown, taking equipment M as an example, for the processes and cycle plans that have not started, the status is displayed as "not started", for the processes and cycle plans that are in progress, the status is displayed as "in progress", and for the processes and cycle plans that have been completed, the status is displayed as "completed". The cycle plans are represented by X and Y, which are the current cycle X and the next cycle Y respectively. The processes are represented by A, B, and C, which are the current process A, the next process B of the current cycle X, and the process C of the next cycle Y respectively. As Figure 1 shown, the automatic discrimination method includes the following steps:

[0061] S100. Calculate the distance between the equipment and the tunnel face. According to the change trend and magnitude of the distance, determine whether there is equipment entering the site. When it is calculated that the distance between the equipment and the tunnel face gradually decreases and is less than the first preset distance P, it is determined that there is equipment entering the site. Identify the type of the equipment as M, which can be identified by taking an image of the equipment, record the entry time of equipment M, and execute step S300. In this embodiment, the value of P is set to 15m. Since all the operation processes are tunnel face operations, that is, close to the tunnel face operations, the entry and exit of the equipment are discriminated by calculating the distance between the equipment and the tunnel face.

[0062] S300. Obtain the current time, traverse the database, compare the current time with the planned time of the cycle plan in the database, and determine whether there is a cycle plan in progress currently.

[0063] If the current time is within the planned time of a certain cyclic plan, that is, between the planned start time and the planned completion time of a certain cyclic plan, it is determined that there is a cyclic plan in "progress". In this embodiment, this cyclic plan is cyclic X, and step S500 is executed;

[0064] If the current time is not between the planned start time and the planned completion time of any cyclic plan, it is determined that there is no cyclic plan in "progress", and step S400 is executed; Generally, before the construction starts, all cyclic plans will be formulated. Therefore, in the case of no cyclic plan in "progress", the next cyclic plan will be automatically executed. However, it may happen that the number of formulated cyclic plans is insufficient or not formulated, that is, there is no cyclic plan in "not started" in the database. Then the system will automatically identify the surrounding rock grade of the current tunnel face and create a cyclic plan of the corresponding template according to the current surrounding rock level of the tunnel face, and set the planned start time to the current time. At this time, the staff can adjust the automatically formulated cyclic plan according to the actual situation on site.

[0065] S400. Compare the type of device M with the types of the set devices, and determine whether device M is any one of the set device types;

[0066] If so, step S410 is executed;

[0067] If not, step S420 is executed;

[0068] S410. Mark the cyclic plan with a planned time greater than the current time and closest to the current time as the connecting cyclic plan. This connecting cyclic plan is cyclic Y, the next cyclic plan of cyclic X. Compare the type of device M with the types of the devices corresponding to the processes in cyclic Y, and determine whether there is a type of device corresponding to a process in the connecting cyclic plan that is the same as the type of device M, that is, determine whether the type of device M is the type of device for any process in cyclic Y;

[0069] If there is, step S430 is executed;

[0070] If there is no, record it as "device M operation" and execute step S900; This situation may be because when formulating the cyclic plan, the process corresponding to device M is not selected. However, during the actual construction process on site, it is found that device M is needed for the corresponding process, or due to some temporary remedial operations, devices that do not belong to any process in the current "in-progress" cyclic X enter the site for operation. Therefore, the current process will not end due to the entry of some non-set devices.

[0071] S420. Compare the type of device M with the type of the device corresponding to the first process in the connection cycle plan to determine whether they are the same. If they are the same, execute step S430. If they are different, record it as "Device M operation" and execute step S900.

[0072] S430. Determine the process in cycle Y where the device corresponding to device M has the same type, that is, process C in cycle Y. Update the status of cycle Y to "In progress", update the status of process C corresponding to device M to "In progress", record the arrival time of device M as the actual start time of the current process C, and execute step S900.

[0073] S500. Traverse the ongoing cycle plan, that is, traverse cycle X. Compare the current time with the planned start time and planned completion time of the processes in cycle X to determine whether there is an ongoing process, that is, determine whether there is a process with the status of "In progress" in cycle X.

[0074] If the current time is between the planned start time and planned completion time of a certain process, it is determined that there is an "In progress" process, and step S700 is executed. In this embodiment, this "In progress" process is A.

[0075] If the current time is not between the planned start time and planned completion time of any process, it is determined that there is no "In progress" process, and step S600 is executed.

[0076] S600. Mark the processes in cycle X whose planned start time is greater than the current time as the first subsequent processes. Compare the type of the incoming device M with the types of the devices corresponding to the first subsequent processes to determine whether there is a device type corresponding to the first subsequent process that is the same as the type of the incoming device, that is, determine whether the type of device M is the trolley type of any "Not started" process after the last "Completed" process.

[0077] If there is, execute step S610.

[0078] If there is not, execute step S820.

[0079] S610. Compare the type of the incoming device M with the types of the set devices to determine whether the incoming device M is any one of the set device types.

[0080] If so, it is determined that the first subsequent process whose corresponding equipment type is the same as the type of the incoming equipment is the current process, that is, the type of equipment M is the same as the equipment type corresponding to process B, and the current process is process B. The status of process B is updated to "in progress", and the actual start time of the second subsequent process corresponding to the incoming equipment type is recorded. The actual start time is the incoming time of the incoming equipment M, and step S900 is executed;

[0081] If not, execute step S620;

[0082] S620, mark the process whose planned time is greater than the current time and closest to the current time as the connecting process, that is, mark the next process of the "ongoing" process A as the connecting process, compare the type of the incoming equipment M with the type of the equipment corresponding to the connecting process, and determine whether the type of the incoming equipment M is the same as the type of the equipment corresponding to the connecting process;

[0083] If yes, it is determined that the current process is in a connecting process, that is, it is currently in process B, and the state of process B is updated to "in progress", and the actual start time of the second subsequent process corresponding to the incoming equipment type is recorded. The actual start time is the incoming time of the incoming equipment M, and step S900 is executed;

[0084] If not, record it as "Device M operation" and execute step S900.

[0085] S700, comparing the type of equipment M with the type of equipment corresponding to process A, and determining whether the type of equipment M is the type of equipment corresponding to process A;

[0086] If yes, it is determined that the current process is still in process A of cycle X, and step S900 is executed;

[0087] If not, execute step S800.

[0088] S800: Mark the process whose planned start time is greater than the planned completion time of the ongoing process as the second subsequent process, that is, mark any "unstarted" process after process A as the second subsequent process, compare the type of incoming equipment M with the type of equipment corresponding to the second subsequent process, and determine whether the type of equipment corresponding to the second subsequent process is the same as the type of incoming equipment M;

[0089] If the type of the equipment corresponding to the second subsequent process is the same as the type of the incoming equipment M, then execute step S810;

[0090] If there is no equipment corresponding to the second subsequent process whose type is the same as the type of the incoming equipment M, execute step S820;

[0091] S810: Compare the type of the incoming device with the type of the set device to determine whether the incoming device M is any of the set device types;

[0092] If so, it is determined that the second subsequent process whose corresponding equipment type is the same as the type of the incoming equipment is the current process, that is, the current process is process B, and the status of process A is changed to "completed", and the last departure time of the equipment corresponding to process A is set to the actual end time of process A, and the status of process B is updated to "in progress", and the actual start time of the second subsequent process corresponding to the incoming equipment type is recorded. The actual start time is the entry time of the incoming equipment M, and step S900 is executed;

[0093] If not, mark the process whose planned time is greater than the current time and closest to the current time as the connecting process, that is, mark the next process of the "in progress" process as the connecting process, compare the type of the incoming equipment M with the type of the equipment corresponding to the connecting process, and determine whether the type of the incoming equipment M is the same as the type of the equipment corresponding to the connecting process; if so, determine that it is currently in the connecting process, that is, it is currently in process B, process A ends, and the last departure time of the equipment corresponding to process A is set to the actual end time of process A, and record the actual start time of the connecting process, and the actual start time is the entry time of the incoming equipment; if not, record it as "equipment M operation" and execute step S900.

[0094] S820. Compare the type of the incoming equipment with the type of the set equipment to determine whether the incoming equipment is any of the set equipment types. If so, determine that the current cycle plan cycle X ends, set the exit time of the previous incoming equipment to the actual end time of the current cycle X, set the actual end time of cycle X to the actual start time of the connecting cycle plan cycle Y, and execute step S410. If not, record it as "equipment M operation" and execute step S900.

[0095] S900, calculate the distance between the device M and the tunnel face, and determine whether the device M has exited. When the calculated distance between the device and the tunnel face gradually increases and is greater than the second preset distance Q, it is determined that a device has exited, and the exit time of the device is recorded, and step S100 is executed. In this embodiment, the Q value is set to 30m.

[0096] According to the process of automatic identification of the above-mentioned processes, the interval between the first entry time and the last exit time of the equipment corresponding to the current process is taken as the actual usage time of the current process, and the interval between the exit time of the equipment corresponding to the current process and the entry time of the equipment corresponding to the next process is taken as the process connection time. The actual time consumption of each process and the actual time consumption of the connection between adjacent processes can be obtained.

[0097] Workers can conduct work efficiency statistics based on the actual time consumed in each process and the actual time consumed in the connection between adjacent processes. For example, Figure 3 As shown, it is the work efficiency statistical result of a single cycle plan in this embodiment. From the figure, the deviation of all processes and process connections in the cycle plan can be directly obtained. The deviation is equal to the actual time consumed minus the assessment time consumed, and the situation of processes and their connections can be analyzed through the deviation situation, providing a decision-making basis for management personnel. Through the work efficiency statistical results, by comparing the execution deviations of each process, relevant assessments and production organization optimization can be assisted, facilitating management personnel's analysis and decision-making, further reducing the connection time between processes, and improving construction efficiency.

[0098] Through the above-mentioned process discrimination method, each process within the excavation support cycle can be automatically identified, the construction progress in the tunnel can be accurately grasped in real time, and the transparency of process management can be achieved. Moreover, the construction work efficiency of each process within the excavation and initial support cycle and the connection time between each process can be automatically and timely statistically analyzed online, the abnormalities of each process operation and process connection can be analyzed, and targeted promotion of process management within the tunnel can be carried out to improve the efficiency of the excavation and initial support cycle.

[0099] The above shows and describes the basic principles and main structural features of the present invention. The present invention is not limited by the above examples. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
