Description

Technical Field

[0001] The present invention relates to a data collection method and system for geological analysis, and in particular to the collection of drilling operation data required for analyzing and judging geological conditions during tunnel construction. Background Art

[0002] Tunnel construction inevitably requires drilling into the mountain. Due to the complexity of the geological structure, it is necessary to timely analyze and judge the geological conditions during the drilling process. For sites with poor geological conditions, measures such as pipe support, anchor hole drilling, and grouting reinforcement are also required to prevent collapse.

[0003] During the drilling process, it is also necessary to adjust the power output at any time according to the geological conditions. For example, when the drill rod encounters a hard rock part, it is necessary to reduce the speed of the power head, increase the rotational torque, and increase the striking energy. When drilling into loose soil or a part with a cavity, it is necessary to reduce the rotational torque and speed up the drilling speed. For geology prone to landslides, it is also necessary to reduce or stop the striking energy. If the power parameters during drilling are not set properly, it will not only affect the drilling efficiency, but also easily cause engineering accidents such as the drill rod getting stuck and the power head being overloaded and damaged.

[0004] Regarding the power adjustment of drilling equipment, the existing technology relies on the experience of construction workers, such as the sound emitted by the equipment during drilling and the mud flowing out of the borehole, to judge the working status of the drilling equipment and make corresponding adjustments to the power. This requires experienced construction workers to be on site and cannot be judged from a distance.

[0005] In the prior art, various parameters of drilling equipment are recorded manually as data preservation. However, the manually recorded data is limited to data that can be read immediately, such as the number of drill rods, the values ​​of various pressure gauges, etc. It is impossible to judge the geological conditions during the drilling process based on these data. For example, during the drilling process, when encountering hard rocks, the drilling speed will slow down, and when entering loose soil or hollows, the drilling speed will increase. The drilling speed is not uniform, and the construction data is recorded at time intervals, so it is impossible to intuitively understand the geological conditions at different depths. Usually, in order to avoid missing useful data, the recording time interval is set to be short, which not only increases the workload of recording, but also easily causes the construction data recorded before and after to be similar, affecting the judgment of the geological conditions.

[0006] Regarding geological condition analysis during drilling, the prior art, for example, in the "Real-time Reflection and Advance Detection System and Method for Geological Conditions Applied to Drilling Rigs (Application No. 201510159253.8)", discloses a technique for comparing the rock physical and mechanical property parameters reflected by the sensor during the drilling process of the drilling rig with the data in the rock formation drilling parameter database to determine the rock formation category and physical and mechanical properties. However, this technique requires the installation of a probe for detecting rock formations, as well as torque sensors, speed sensors, shaft pressure sensors and other sensors on the drilling rig, which has a complex structure and is only applicable to geological surveys before actual tunnel excavation.

[0007] The first purpose of the present invention is to utilize existing construction equipment to obtain power data of the drilling rig during tunnel construction, so that construction personnel can make judgments on the geological conditions while drilling.

[0008] The second purpose is to provide construction personnel with drilling operation data that allows them to intuitively analyze the geological conditions. Summary of the invention

[0009] The first technical solution of the present invention is a data collection method for geological analysis, which is characterized in that it includes the following steps: a drilling depth data collection step, in which a mountain is drilled using a drilling device, and while drilling, the drilling depth data m of the drill rod entering the mountain is collected according to a prescribed period; a power sensor detection value collection step, in which the detection value of the power sensor is triggered for each increase in the drilling depth data m by a unit depth b, and the power sensor is used to detect the output power of the drilling equipment; a drill rod power data calculation step, in which the power data of the drill rod is calculated according to the detection value of the power sensor; a data association step, in which the current drilling depth data m is associated with the calculated power data to obtain drilling operation data; a data storage step, in which each of the drilling operation data is uploaded to a data management platform in real time for storage to obtain a drilling operation data group consisting of different drilling depths.

[0010] Therefore, construction workers can analyze the current geological conditions based on the power data obtained while drilling, and adjust the power of the drill rod or reinforce the work site to prevent landslides when necessary.

[0011] And the drilling operation data group obtained in the drilling process is the dynamic data collected at the sampling point with the depth of integer multiples of the unit depth b. Therefore, each drilling operation data corresponds to a different drilling depth. The construction personnel can intuitively know the drilling depth corresponding to the dynamic data according to the serial number of the uploaded drilling operation data. Not only can they judge the geological conditions of the current drilling location, but they can also judge the thickness of different geological layers according to the changes in the dynamic data.

[0012] Since the power data related to drilling is saved in real time on the data management platform as a data archive, the labor cost required for manual recording is saved.

[0013] Preferably, the unit depth b is 6 to 8 cm.

[0014] Therefore, the corresponding power data can be continuously acquired at intervals of 6 to 8 cm in drilling depth, which not only meets the needs of adjusting the drill pipe power in engineering, but also meets the detection accuracy required for the analysis of geological layer thickness. Compared with intensive collection, it reduces data redundancy and improves the efficiency of collection and processing.

[0015] Preferably, the drilling equipment includes a power head for driving the drill rod, the power head is driven by a thrust cylinder to drive the drill rod to advance and retreat, the drill rod is driven to rotate by a rotary cylinder, and the drill rod is driven to impact by a striking cylinder, when the drill rod is advanced, the wire of a wire encoder is pulled to measure the drilling depth, and the power sensor includes any one or any combination of a thrust cylinder pressure sensor for detecting the thrust cylinder pressure, a rotary cylinder pressure sensor for detecting the rotary cylinder pressure, and a striking cylinder pressure sensor for detecting the striking cylinder pressure.

[0016] The drilling depth data acquisition step acquires the output value k of the wire encoder, and calculates the drilling depth data m of the drill rod based on the output value k; the power sensor detection value acquisition step acquires the output value k of the wire encoder, acquires the propulsion cylinder oil supply pressure Pt by the propulsion cylinder pressure sensor, acquires the rotation cylinder oil supply pressure Pm by the rotation cylinder pressure sensor, and acquires the strike cylinder oil supply pressure Pc by the strike cylinder pressure sensor.

[0017] The drill rod power data calculation step calculates the drilling speed V according to the time t spent on drilling a unit depth b or the drilling depth within a specified time, calculates the propulsion force F according to the propulsion cylinder oil supply pressure Pt, calculates the rotation torque N according to the rotation cylinder oil supply pressure Pm, calculates the striking energy Wd according to the striking cylinder oil supply pressure Pc and striking efficiency, calculates the number of strikes U according to the striking cylinder oil supply pressure Pc, and calculates the destructive energy Wp according to the drilling speed V, the cross-sectional area of ​​the drill rod, the number of strikes U, and the striking energy Wd. Any one or any combination of the drilling speed V, propulsion force F, rotation torque N, striking energy Wd, the number of strikes U, and the destructive energy Wp is associated with the current drilling depth data m as the power data of the drill rod.

[0018] Since the states represented by the propulsion cylinder oil supply pressure Pt, the rotation cylinder oil supply pressure Pm, and the striking cylinder oil supply pressure Pc are too abstract, the construction personnel cannot immediately judge the geological state even if they read the propulsion cylinder oil supply pressure Pt, the rotation cylinder oil supply pressure Pm, and the striking cylinder oil supply pressure Pc, that is, they lack intuitiveness. In the present invention, since the propulsion force F, the rotation torque N, the striking energy Wd, the destructive energy Wp, and the number of strikes U of the drill rod are calculated according to the propulsion cylinder oil supply pressure Pt, the rotation cylinder oil supply pressure Pm, and the striking cylinder oil supply pressure Pc, the construction personnel can intuitively judge the geological conditions during drilling.

[0019] Since the wire encoder, thrust cylinder pressure sensor, rotation cylinder pressure sensor and impact cylinder pressure sensor are all existing settings on the drilling equipment, the drilling depth data can be collected directly on the existing drilling equipment by compiling software, thereby reducing costs.

[0020] Preferably, the drilling equipment supplies water into the borehole while drilling, and the power sensor also includes a water supply flow sensor for detecting the water supply flow rate. In the power sensor detection value acquisition step, the detection value of the water supply flow sensor is also acquired; in the drill rod power data calculation step, the water supply flow data q is calculated according to the detection value of the water supply flow sensor; in the data association step, the power data including the water supply flow data q is associated with the current drilling depth data m to obtain the drilling operation data.

[0021] Since the power data also includes the water delivery flow data q, the geological conditions of the current borehole can be judged more accurately.

[0022] Preferably, in the drilling depth data acquisition step, when an interruption signal that causes the power head to interrupt drilling is received, the current drilling depth data m is recorded, and the output value k of the wire encoder is assigned to the variable n. When drilling is resumed, the drilling depth data m of the drill rod is calculated based on the output value k of the wire encoder and the variable n.

[0023] Therefore, when the power head needs to be moved backwards to install a drill rod, the movement of the power head will not cause an error in calculating the drilling depth, in which the obtained drilling depth is less than the actual drilling depth, thereby ensuring the accuracy of the drilling depth data.

[0024] Preferably, the method further includes a display step, wherein the data management platform acquires the drilling operation data in real time, and displays the drilling operation data on a display screen in real time according to the order of data collection.

[0025] Since the drilling operation data is displayed on the display screen in real time according to the order of data collection, construction personnel can not only intuitively judge the current geological conditions based on the power data, but also judge the thickness of the geological layer according to the changes in the power data. When necessary, they can promptly adjust the power of the drill rod or reinforce the site to prevent landslides.

[0026] The second technical solution is a data acquisition system for geological analysis, which is characterized by comprising: a drilling depth calculation module, which uses a drilling device to drill a mountain, and calculates the drilling depth data m of the drill rod entering the mountain according to a specified period while drilling; a data acquisition module, which triggers the acquisition of the detection value of a power sensor for each increase in a unit depth b of the drilling depth data m, and the power sensor is used to detect the output power of the drilling equipment; a drill rod power data calculation module, which calculates the power data of the drill rod according to the detection value of the power sensor; a data association module, which associates the current drilling depth data m with the calculated power data to obtain drilling operation data; a drilling operation data storage module, which uploads each of the drilling operation data to a data management platform in real time for storage, and obtains a drilling operation data group consisting of different drilling depths.

[0027] Therefore, similar to the first technical solution, in the second technical solution, construction personnel can judge the current geological conditions based on the acquired power data while drilling, and timely adjust the power of the drill rod or reinforce the work site to prevent landslides when necessary. According to the serial number of the uploaded drilling operation data, construction personnel can intuitively know the drilling depth corresponding to the power data, and can not only judge the geological conditions of the current drilling location, but also judge the thickness of different geological layers according to the changes in the power data.

[0028] Preferably, the drilling equipment includes a power head for driving the drill rod, the power head is driven by a thrust cylinder to drive the drill rod to advance and retreat, the drill rod is driven to rotate by a rotary cylinder, and the drill rod is driven to impact by a striking cylinder, when the drill rod is advanced, the wire of a wire encoder is pulled to measure the drilling depth, the power sensor includes any one or any combination of a thrust cylinder pressure sensor for detecting the thrust cylinder pressure, a rotary cylinder pressure sensor for detecting the rotary cylinder pressure, and a striking cylinder pressure sensor for detecting the striking cylinder pressure, and the drilling depth calculation module calculates the drilling depth data m of the drill rod according to the output value k of the wire encoder.

[0029] The data acquisition module obtains the output value k of the wire encoder, acquires the propulsion cylinder oil supply pressure Pt by the propulsion cylinder pressure sensor, acquires the rotation cylinder oil supply pressure Pm by the rotation cylinder pressure sensor, and acquires the striking cylinder oil supply pressure Pc by the striking cylinder pressure sensor. The drill rod power data calculation module includes a drilling speed calculation module, a propulsion force calculation module, a rotation torque calculation module, a striking energy calculation module, a destructive energy calculation module, a striking number calculation module, and a water delivery flow calculation module.

[0030] The drilling speed calculation module calculates the drilling speed V according to the time t spent on drilling a unit depth b or the drilling depth within a specified time; the propulsion force calculation module calculates the propulsion force F according to the propulsion cylinder oil supply pressure Pt; the rotational torque calculation module calculates the rotational torque N according to the rotation cylinder oil supply pressure Pm; the striking energy calculation module calculates the striking energy Wd according to the striking cylinder oil supply pressure Pc and the striking efficiency; the strike number calculation module calculates the strike number U according to the striking cylinder oil supply pressure Pc; the destructive energy calculation module calculates the destructive energy Wp according to the drilling speed V, the cross-sectional area of ​​the drill rod, the strike number U, and the striking energy Wd.

[0031] Any one or any combination of the drilling speed V, propulsion force F, rotation torque N, striking energy Wd and striking number U, and destructive energy Wp is used as the power data of the drill rod and is associated with the current drilling depth data m.

[0032] Therefore, compared with the thrust cylinder oil supply pressure Pt, the rotation cylinder oil supply pressure Pm, and the impact cylinder oil supply pressure Pc, the drill rod's thrust force F, rotation torque N, impact energy Wd, destructive energy Wp, and number of impacts U are more intuitive, and construction personnel can intuitively analyze the geological conditions during drilling.

[0033] Preferably, the drilling equipment delivers water into the borehole while drilling, the power sensor further comprises a water flow sensor for detecting the water flow rate, and the data acquisition module further acquires the detection value of the water flow sensor; the drill rod power data calculation module further comprises calculating the water flow data q according to the detection value of the water flow sensor;

[0034] The data association module associates the power data including the water delivery flow data q with the current drilling depth data m to obtain drilling operation data.

[0035] Since the power data also includes water delivery flow data q, construction personnel can more accurately judge the current geological conditions of the borehole.

[0036] Preferably, it also includes a display screen for displaying the drilling operation data. The drilling operation data is acquired in real time by the data management platform and displayed in real time on the display screen in the order of data acquisition.

[0037] Therefore, construction workers can not only intuitively judge the current geological conditions based on the power data, but also determine the thickness of the geological layer based on the changes in the power data. When necessary, they can promptly adjust the power of the drill rod or reinforce the site to prevent landslides. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Reference numerals refer to components and technologies in the present invention so that the advantages and features of the present invention can be more easily understood when implemented in a suitable environment.

[0045] Figure 1 This is a block diagram to illustrate the relationship between the construction vehicles during tunnel boring construction and the data acquisition system for geological analysis. Figure 1 As shown, the construction vehicle 300 is equipped with a power head 200 and a drilling rig console 100, and the power head 200 drives the drill rod to drill a hole in the mountain. Figure 4 and 5 That is, the power head 200 is installed on a movable vehicle body, and is driven by a propulsion cylinder (not shown) to drive the drill rod 220 to advance and retreat, and the drill rod 220 is driven to rotate by a rotation cylinder (not shown), and the percussion cylinder (not shown) percusses the drill rod 220. A wire encoder 210 is installed on the vehicle body, and when the power head 200 drives the drill rod 220 to advance, the wire 210a of the wire encoder 210 is pulled (see Figure 5), the wire encoder 210 outputs a corresponding electrical signal according to the length of the wire being pulled.

[0046] The drilling rig control console 100 is operated by construction personnel and is used to control the movement and output power of the power head 200, including a propulsion cylinder flow control 101 for controlling the flow of hydraulic oil in the propulsion cylinder, a power head forward and backward control 102, a rotating cylinder flow control 103 for controlling the flow of hydraulic oil entering the rotating cylinder, a striking cylinder flow control 104 for controlling the flow of hydraulic oil entering the striking cylinder, an interrupt button 105, and a water supply flow control 106 for controlling the supply of water to the borehole.

[0047] The interrupt button 105 is used to control the interruption of the data acquisition module 10 during the data acquisition process. Press it once and the data acquisition module 10 will interrupt the data acquisition. Press it again and the data acquisition will be resumed. This cycle repeats over and over again. During the interruption, the previous data is retained and no data loss will be caused.

[0048] Sensors are installed in each oil pressure pipeline of the power head 200 to monitor the pressure of each oil cylinder, namely, the thrust cylinder pressure sensor 201, the rotation cylinder pressure sensor 203, and the striking cylinder pressure sensor 204, which are used to detect the oil supply pressure Pt of the thrust cylinder, the oil supply pressure Pm of the rotation cylinder, and the oil supply pressure Pc of the striking cylinder, respectively. A water supply flow sensor 206 is also provided in the construction vehicle to detect the water supply flow during the drilling process.

[0049] The thrust cylinder pressure sensor 201, the rotation cylinder pressure sensor 203, the striking cylinder pressure sensor 204 and the water supply flow sensor 206 constitute the power sensor in the claims.

[0050] The data acquisition system 60 for geological analysis is composed of a data acquisition module 10 , a drilling depth calculation module 21 , a drill pipe power data calculation module 20 , a data association module 30 , and a drilling operation data storage module 40 .

[0051] The data acquisition module 10 collects data respectively from the wire encoder 210, the thrust cylinder pressure sensor 201, the rotation cylinder pressure sensor 203, the strike cylinder pressure sensor 204 and the water supply flow sensor 206, that is, it collects the output value k of the wire encoder 210, the oil supply pressure Pt of the thrust cylinder, the oil supply pressure Pm of the rotation cylinder, the oil supply pressure Pc of the strike cylinder and the detection value of the water supply flow.

[0052] In this embodiment, the data acquisition module 10 collects the output value k of the wire encoder 210 according to the control cycle (prescribed cycle), and inputs the output value k to the drilling depth calculation module 21. The drilling depth calculation module 21 calculates the drilling depth data m of the drill rod 220 according to the output value k and the conversion coefficient x. The drilling depth calculation module 21 outputs a trigger signal every time it calculates a unit depth b, triggering the data acquisition module 10 to collect the detection values ​​of each power sensor. In this embodiment, the unit depth b is 7 cm.

[0053] The drill pipe power data calculation module 20 calculates the power data on the drill pipe according to the detection values ​​of each power sensor collected by the data acquisition module 10: thrust F, drilling speed V, rotation torque N, destructive energy Wp, number of strikes U and water flow data q.

[0054] The data association module 30 associates the current drilling depth data m with the power data to obtain drilling operation data. As the drilling depth m increases, a drilling operation data is obtained for each unit depth b drilled. Therefore, as the drilling proceeds, the power data is continuously collected, and finally a drilling operation data group consisting of the power data at the depth of an integer multiple of the unit depth b is obtained.

[0055] The drilling operation data storage module 40 uploads the obtained drilling operation data to the data management platform in real time for storage and provides it to construction personnel for geological analysis. In this embodiment, the data management platform adopts a cloud platform.

[0056] Figure 2 This is the overall structural diagram of the data acquisition system for geological analysis. Figure 2 The geological analysis data acquisition system of the present invention is described in detail. Figure 2 As shown, the drill pipe power data calculation module 20 includes a drilling speed calculation module 22, a propulsion force calculation module 23, a rotation torque calculation module 24, an impact energy calculation module 25, a destructive energy calculation module 26, a strike number calculation module 27, and a water delivery flow calculation module 28.

[0057] The drilling depth calculation module 21 calculates the drilling depth data m of the drill rod according to the output value k of the wire encoder 210 .

[0058] The drilling speed calculation module 22 obtains the drilling depth data m from the drilling depth calculation module 21, and calculates the drilling speed V according to the time t spent on drilling a unit depth b or the drilling depth within a specified time.

[0059] The propulsion force calculation module 23 calculates the propulsion force F according to the propulsion cylinder oil supply pressure Pt detected by the propulsion cylinder pressure sensor 201 .

[0060] The rotation torque calculation module 24 calculates the rotation torque N according to the rotation cylinder oil supply pressure Pm detected by the rotation cylinder pressure sensor 203 .

[0061] The striking energy calculation module 25 calculates the striking energy Wd according to the striking cylinder oil supply pressure Pc detected by the striking cylinder pressure sensor 204 and the striking efficiency.

[0062] The striking number calculation module 27 calculates the striking number U according to the striking cylinder oil supply pressure Pc detected by the striking cylinder pressure sensor 204 .

[0063] The destructive energy calculation module calculates the destructive energy Wp according to the drilling speed V, the cross-sectional area of ​​the drill rod, the number of blows U, and the blow energy Wd.

[0064] The calculation formula is as follows:

[0065] Drilling speed V = unit depth / time spent advancing unit depth (e.g. 7 cm) or drilling depth per unit time (e.g. 500 ms control cycle); rotational torque N = rotational cylinder oil supply pressure Pm × rotational torque coefficient constant; striking energy = striking cylinder oil supply pressure Pc × striking efficiency; destructive energy = (striking energy × number of strikes) / (cross-sectional area of ​​drill rod × drilling speed V); number of strikes = (striking cylinder oil supply pressure Pc × striking efficiency) + number of strikes.

[0066] Every time the drilling depth data m calculated by the drilling depth calculation module 21 increases by 7 cm, the data acquisition module 10 is triggered to collect power data once, that is, the propulsion cylinder pressure sensor 201, the rotation cylinder pressure sensor 203, the striking cylinder pressure sensor 204 and the water supply flow sensor 206 respectively obtain the oil supply pressure Pt of the propulsion cylinder, the oil supply pressure Pm of the rotation cylinder, the oil supply pressure Pc of the striking cylinder and the water supply flow detection value, and calculate the rotational torque N, striking energy Wd, number of strikes U, destructive energy Wp and water supply flow data q.

[0067] After the drilling depth data m and the corresponding power data are associated in the data association module 30 to obtain the drilling operation data, the drilling operation data storage module 40 uploads the drilling operation data to the data management platform 400 for storage in real time. In this embodiment, the data management platform 400 adopts a cloud platform. Therefore, the drilling operation data is not only stored as a data file on the data management platform 400 but also sent to the computer 500 in real time through the network, and displayed in real time on the display screen 510 in the form of numbers or icons according to the order of data collection.

[0068] In the present invention, due to utilizing existing sensors in the construction vehicle such as the propulsion cylinder pressure sensor 201, the rotation cylinder pressure sensor 203, and the striking cylinder pressure sensor 204, there is no need to install additional sensors, and data for geological analysis can be provided by compiling software.

[0069] That is, the outputs of the propulsion cylinder pressure sensor 201, the rotation cylinder pressure sensor 203, the striking cylinder pressure sensor 204 and other sensors are only abstract pressure values, which lack intuitiveness, and the construction personnel cannot associate these pressure values ​​with specific geological conditions. In addition, some cylinders, such as the striking cylinder, are associated with striking energy and striking times at the same time, and the destructive energy provided is also related to the drilling speed. Based on these abstract pressure values, it is difficult for the construction personnel to associate them with the geological conditions and make a correct judgment on the geological conditions.

[0070] In the present invention, what is provided to construction personnel is not the abstract pressure value detected by each sensor, but the pressure value based on each oil cylinder, which is converted into a value with physical meaning, such as the drilling speed, the torque on the drill rod, and the striking energy. Therefore, construction personnel can intuitively judge the geological conditions.

[0071] Since the drilling operation data group obtained during the drilling process is the dynamic data collected at sampling points with depths that are integer multiples of the unit depth b, each drilling operation data corresponds to a different drilling depth. The construction personnel only need to follow the serial number of the uploaded drilling operation data to know the drilling depth corresponding to the dynamic data, and intuitively judge the geological conditions of different drilling depths and the thickness of different geological layers.

[0072] Since the power data related to drilling is saved in real time on the data management platform 400 as a data file, the labor cost required for manual recording is saved. In addition, the construction personnel can obtain the drilling operation data of different sites at the same work site, and analyze the geological conditions of different sites based on the power data displayed on the display screen 510 of the computer 500 without going to the site, thus saving labor costs. When necessary, the on-site staff can be instructed in time to adjust the power of the drill rod or reinforce the work site to prevent landslides.

[0073] The following is an explanation of the drilling operation data collection process. Figure 3 It is a flow chart of data collection for geological analysis.

[0074] like Figure 3 As shown, in step S10, the power head 200 is retracted to the rearmost position and the drill rod 220 is located at a predetermined drilling position. Figure 4As shown, the construction vehicle 300 is moved to a predetermined position, the power head 200 is returned to the rearmost position, a drill rod 200 is installed on the power head 200, and the head of the drill rod 200 is placed against the mountain 600. After the preparation work is completed, step S20 is entered.

[0075] In step S20, the construction personnel operate the drilling depth calculation module 21 to clear the output value k of the wire encoder 210, and then start the data acquisition module 10 to start collecting data.

[0076] Step S30 , triggering a forward signal of the power head 200 , so that the power head 200 drives the drill rod 220 to move forward and drill a hole in the mountain 600 .

[0077] Step S40, reset the timer value t and start the timer. The timer value t is used to calculate the average drilling speed V according to the unit drilling depth (7 cm).

[0078] Before the forward trigger signal of the power head 200 is issued, the construction personnel set various power parameters on the drilling rig control console 100. For example, through the propulsion cylinder flow control 101, the rotation cylinder flow control 103, the impact cylinder flow control 104, and the water delivery flow control 106, the oil pressure flow of the propulsion cylinder, the oil pressure flow of the rotation cylinder, the oil pressure flow of the impact cylinder and the water delivery flow are set.

[0079] During the drilling process, the pressure of each oil cylinder will change with the increase or decrease of the load. For example, when the geology is soft or hollow, the oil pressure of each oil cylinder decreases. When encountering heavy loads such as rocks, the pressure of the oil cylinder increases. Therefore, the size of the oil cylinder pressure reflects the geological conditions at the drilling site. Since the geological conditions reflected by the oil cylinder pressure lack intuitiveness, construction personnel cannot correctly judge the geological conditions based on the oil cylinder pressure. In the present invention, the propulsion force F, rotation torque N, striking energy Wd, number of strikes U, and destructive energy Wp are calculated based on the oil cylinder pressure, so that construction personnel can intuitively judge the geological conditions.

[0080] Step S50: During the drilling process, the data acquisition module 10 reads the output value k of the wire encoder 210 according to the control cycle. At this time, only the output value k of the wire encoder 210 needs to be read, and the detection values ​​of other pressure sensors are temporarily not needed and may or may not be read.

[0081] Step S60, the drilling depth calculation module 21 calculates the drilling depth data m according to the output value k and the conversion coefficient x. The calculation formula is m=m+(kn)x, and initially m=0, n=0.

[0082] In step S70 , the data acquisition module 10 determines whether the interrupt button 105 is pressed. If not (NO), the process proceeds to step 80 . If yes (YES), the process proceeds to step S160 .

[0083] In step S80 , the data acquisition module 10 determines whether the drilling depth data m has advanced by 7 cm (unit depth). If yes (YES), the process goes to step S90 . If no (NO), the process goes back to step S50 and repeats the above steps.

[0084] Step S90, the drilling speed calculation module 22 reads the timing value t of the timer.

[0085] In step S100, the drilling speed calculation module 22 calculates the average speed at a drilling unit depth of 7 cm as the drilling speed V according to the timing value t of the timer and the drilling depth of 7 cm.

[0086] Step 80 and step 110 correspond to the step of collecting detection values ​​of the power sensor in the claims.

[0087] Step S110 , triggering the data acquisition module 10 to acquire the detection values ​​of the propulsion cylinder pressure sensor 201 , the rotation cylinder pressure sensor 203 , the striking cylinder pressure sensor 204 and the detection value of the water supply flow sensor 206 .

[0088] In step S120, the rotation torque calculation module 24 calculates the rotation torque N according to the rotation cylinder oil supply pressure Pm detected by the rotation cylinder pressure sensor 203. The striking energy calculation module 25 calculates the striking energy Wd according to the striking cylinder oil supply pressure Pc and the striking efficiency detected by the striking cylinder pressure sensor 204. The striking number calculation module 27 calculates the striking number U according to the striking cylinder oil supply pressure Pc, and the water supply flow calculation module 28 calculates the water supply flow data q according to the water supply flow detection value.

[0089] Step S100 and step S120 correspond to the drill pipe power data calculation step in the claims.

[0090] In step S130 , the data association module 30 associates the current drilling depth data m (an integer multiple of the unit depth) with the propulsion force F, the rotation torque N, the striking energy Wd, the destructive energy Wp, the number of strikes U and the water flow rate data q to obtain the current drilling operation data.

[0091] Step 130 corresponds to the data association step in the claims.

[0092] Step S140 , the drilling operation data storage module 40 uploads the current drilling operation data to the data management platform 400 for storage in real time.

[0093] Step 140 corresponds to the data storage step in the claims.

[0094] Step S150, the drilling operation data uploaded to the data management platform 400 is sent to the display screen 510 of the computer 500 in real time and displayed in sequence in the form of numbers or charts. Therefore, the construction personnel can remotely study and judge the geological conditions at the drilling location.

[0095] Step 150 corresponds to the step shown in the claims.

[0096] Then, the process returns to step S40, and the timer value t is reset and then restarted. As the drilling depth increases, the above steps are repeated continuously. For every 7 cm (unit depth) increase in the drilling depth, a drilling operation data corresponding to the drilling depth is uploaded to the data management platform (cloud platform) 400 for storage, and the drilling operation data obtained at different drilling depths are sequentially displayed on the display screen 510 of the computer 500. Therefore, the construction personnel can intuitively know the depth of the drill rod entering the mountain 600, and use the dynamic data to analyze the geological conditions at that location.

[0097] Figure 5 This is a diagram illustrating the status of construction vehicles during tunnel boring construction. Figure 5 As shown, as the drill rod 220 moves forward, the depth of the borehole 620 increases continuously, and the power head 200 moves forward continuously. When it moves to the end point, it is necessary to retract the power head and install another drill rod. At this time, the construction personnel press the interrupt button 105, and the data acquisition module 10 stops collecting data. The construction personnel retract the power head 200 and install a new drill rod.

[0098] At this time, in step S70, the data acquisition module 10 determines that the interrupt button 105 is pressed, and then enters step S160.

[0099] In step S160, the data acquisition module 10 records the current drilling depth data m, and assigns the output value k of the wire encoder 210 to the variable n, so as to avoid calculation errors of the drilling depth data m caused by installing a drill rod on the mobile power head 200.

[0100] In step S170 , the data acquisition module 10 determines whether the interrupt button 105 is pressed again. If not (NO), the module continues to wait until the interrupt button 105 is pressed again, and then returns to step S50 . The data acquisition module 10 restarts to read the output value k of the wire encoder 210 .

[0101] Step 50 , step 60 , step S70 , step S160 , and step S170 correspond to the drilling depth data collection steps in the claims.

[0102] Therefore, when the power head needs to be moved backwards to install a drill rod, the drilling depth calculated will not be less than the actual depth due to the backward movement of the power head, thus ensuring the accuracy of the drilling depth data.

[0103] Repeat the above steps until the drilling is completed. During the entire drilling process, a dynamic data is collected for every 7 cm of drilling, and then associated with the drilling depth data m as drilling operation data and uploaded to the data management platform 400, and displayed on the display screen 510 of the computer 500.

[0104] Therefore, for Figure 4 , 5 In the mountain 600 with complex geological structure shown in the figure, the borehole 620 passes through different geological structures. During the drilling process, the power acting on the drill rod 220, namely the drilling speed V, drilling torque N, striking energy Wd, number of strikes U, and destructive energy Wp, will change with the change of geological structure. For example, when drilling on the initial rock, the drilling speed V is low, while the drilling torque N is large, the striking energy Wd, number of strikes U, and destructive energy Wp are also high. As the drilling goes deeper, when drilling into the hollow 610, the drilling speed V will increase, while the drilling torque N, striking energy Wd, number of strikes U, and destructive energy Wp will all decrease. The construction personnel can judge from this that the rock has been penetrated and entered into the soft or hollow geological structure, and notify the operator to adjust the flow of the propulsion cylinder to speed up the drilling speed. Afterwards, when the borehole enters the hard layer containing gravel, the load on the drill rod 220 increases, causing the drilling speed V to decrease, while the drilling torque N, impact energy Wd, number of impacts U, and destructive energy Wp increase. The construction personnel can determine that the soft geology has been penetrated. To avoid overloading of the power head 200 and the drill rod 220 being stuck in the borehole, the operator can lower the flow of the thrust cylinder and increase the flow of the rotating cylinder and the impact cylinder to adapt to the hard geological structure.

[0105] In this embodiment, the computer 500 acquires the drilling operation data through the data management platform (cloud platform) 400, and displays it in real time on the display screen 510 in the form of a chart in the order of data collection. Therefore, the construction personnel or geological analysts can track the changes in the power data, intuitively judge the geological conditions of the current drilling depth, and adjust the power input to the power head 200 in time on the drilling rig console 100 according to the results of the judgment.

[0106] Moreover, the accuracy of the drilling operation data will not be affected for construction that requires multiple drill rods to drill holes.

[0107] As the unit depth, 7 cm is used in this embodiment, but it can be adjusted as needed. Since the depth range near 7 cm (for example, 3 to 15 cm) covers the range of changes in geological conditions that need to be considered in the borehole, even if there are local geological differences in the depth range smaller than 3 cm, the impact on the borehole is not significant, and there is no need to adjust the power parameters of the drilling equipment. A range smaller than 3 cm can certainly increase the analysis and judgment of changes in small geological conditions, but it is of little practical significance. Moreover, if the unit depth is set too small, it is easy to pick up geological unevenness and noise caused by gravel, which is not conducive to the analysis and judgment of geological conditions. On the contrary, if the unit depth is set too large, it is easy to miss data and cannot timely judge changes in geological conditions. It can be selected in the range of 3 to 15 cm, preferably in the range of 6 to 8 cm.

[0108] Modifications of the present invention will be described below. Figure 6 This is a flowchart of data collection for geological analysis of a modified example.

[0109] exist Figure 3 In the process, a timer is set to measure the time taken to drill to a unit depth of 7 cm, and the average speed V during the drilling process is calculated based on the measured time t. Figure 6 In the modified example, the timer is omitted and the drilling depth of each control cycle (500ms) is used instead of the timer calculation time. Figure 3 The S40 in Figure 3 Step 90 in is changed to step 90'.

[0110] and Figure 3 compared to, Figure 6 The data acquisition module 10 calculates the drilling depth in each control cycle (500ms), and when the drilling depth reaches an integer multiple of the unit depth (7cm), it enters step 90' to read the drilling depth obtained in the last cycle.

[0111] In step 100, the drilling speed V is calculated using the drilling depth and control cycle t obtained in step 90'.

[0112] As a technical solution, except that the drilling speed V is calculated using the drilling depth of the last control cycle, which is different from the previous embodiment, the rest are the same and have the same technical effects. Please refer to the previous description for details and will not be repeated here.

[0113] It should be noted that the above-mentioned embodiments illustrate rather than limit the invention and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims.
