Description

Technical Field

[0001] This invention relates to the field of intelligent and information-based construction of water conservancy and hydropower projects, specifically a high-pressure jet grouting anti-seepage wall construction control system. Background Technology

[0002] High-pressure jet grouting cutoff wall construction often employs integrated drilling and grouting equipment. First, a high-speed jet stream formed by high-pressure water or high-pressure grout impacts, cuts, and breaks up the soil strata. After reaching the target depth, the nozzle is opened for grouting while the spraying rod is raised, forming a wall composed of a mixture of the original stratum material and cement grout. It is widely used in water conservancy and hydropower seepage prevention projects. The quality of the completed high-pressure jet grouting cutoff wall depends on the construction control during the spraying process.

[0003] Currently, high-pressure jet grouting cutoff wall construction typically maintains the same construction control parameters during the jetting process, including the same jetting speed, grouting pressure, and nozzle angle. However, in actual projects, the geological conditions within the borehole are complex, often exhibiting weak interlayers, stratigraphic boundaries, faults, and joint fracture zones, which frequently do not perfectly match the preliminary geological survey data. Applying the same jetting control parameters to locations with weak interlayers as to locations with thick, intact lithology is clearly unreasonable. Simply put, under-jetting at weak interlayer locations will result in incomplete grouting and closure of the weak surfaces, leading to defects in the cutoff wall; conversely, over-jetting at locations with thick, intact lithology will waste grout, increase construction costs, and cause environmental pollution due to excess grout overflowing from the borehole opening.

[0004] Therefore, it is necessary to collect feedback information during the drilling process, including the lithological characteristics and distribution within the borehole, and the presence of weak interlayers, to obtain the parameters and geological conditions of the soil and rock mass along the borehole. Based on the parameter information in the existing database, this information can be used to achieve precise control of the mechanical equipment during the high-pressure jet grouting cutoff wall construction, guiding the construction process and helping to improve the economy, quality assurance, and environmental friendliness of the high-pressure jet grouting cutoff wall construction. Accurately obtaining the properties and parameters of the soil and rock mass inside and around the borehole is fundamental to ensuring the effectiveness of the jet grouting construction. Summary of the Invention

[0005] The purpose of this invention is to provide a high-pressure jet grouting anti-seepage wall construction control system. This system can accurately feed back the geological conditions inside and around the borehole, including the lithological characteristics and distribution inside the borehole, the presence of weak interlayers, etc., so as to achieve refined control of mechanical equipment during the construction of the high-pressure jet grouting anti-seepage wall and guide the construction of the high-pressure jet grouting anti-seepage wall.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a high-pressure jet grouting anti-seepage wall construction control system, characterized in that: it mainly includes a drilling and jet grouting integrated equipment, a monitoring-feedback device, and an artificial intelligence algorithm computer, characterized in that: the drilling and jet grouting integrated equipment has a built-in cylindrical protection device, the monitoring-feedback device is fixed inside the cylindrical protection device, and the monitoring-feedback device is connected to the artificial intelligence algorithm computer through a signal line.

[0007] Furthermore, the integrated drilling and grouting equipment includes a drill bit, drill rod, nozzle, high-pressure water pipe, grouting pipe, and air supply pipe; the drill rod and drill bit are connected by a cylindrical protective device, the drill bit is equipped with a nozzle, and the drill rod contains a high-pressure water pipe, grouting pipe, and air supply pipe. The grouting pipe is located in the middle of the drill rod, and the high-pressure water pipe and air supply pipe are located on both sides of the grouting pipe.

[0008] Furthermore, the cylindrical protective device has a double-layer structure on both sides. The outer side is a high-strength metal plate, and the inner side is a high-definition scratch-resistant glass. The outer diameter of the cylindrical protective device is slightly smaller than the diameter of the drill rod and the drill bit, and the diameter of the drill rod and the drill bit are the same. The cylindrical protective device extends into a small part of the drill rod and the drill bit. The outer high-strength metal plate is in close contact with the inner wall of the drill rod and the drill bit, and a middle partition is provided in the middle of the cylindrical protective device.

[0009] Furthermore, a spring-telescopic device is installed between the drill pipe and the cylindrical protective device. The spring-telescopic device includes a rotating paddle, a metal ring, a metal rod, a stiff spring, and a metal baffle. Several stiff springs are arranged inside the drill pipe, close to the drill pipe wall. The stiff springs are set on a small-diameter metal rod. The bottom of the metal rod is connected to the outer high-strength metal plate, and the top of the metal rod is connected to the metal ring. The metal rod, stiff spring, and metal ring are fixed by welding. A radially rotating paddle is welded to the upper edge of the inner wall of the outer high-strength metal plate and the upper edge of the outer wall of the inner high-definition scratch-resistant glass. A notch is made on the outer wall of the drill pipe, and the rotating paddle is welded to the metal ring through the notch.

[0010] Furthermore, the metal baffle is divided into a metal baffle on the outer high-strength metal plate and a metal baffle on the inner high-definition scratch-resistant glass. Rotating the lever causes the metal rod, along with the hard spring, the outer high-strength metal plate, and the metal baffle, to rotate within the notch range.

[0011] Furthermore, when the outer high-strength metal plate is in the open state, the metal baffle on the outer high-strength metal plate rotates out of the range of the metal baffle on the inner high-definition scratch-resistant glass. When the outer high-strength metal plate is in the closed state, the metal baffle on the outer high-strength metal plate rotates to below the metal baffle on the inner high-definition scratch-resistant glass. The number and size of the metal baffles on the outer high-strength metal plate and the inner high-definition scratch-resistant glass are the same, and the diameter of the metal ring is the same as that of the outer high-strength metal plate.

[0012] Furthermore, the monitoring-feedback equipment includes a panoramic camera probe and an acoustic transducer. The cylindrical protection device is divided into upper and lower layers by a middle partition. The upper layer has an acoustic transducer welded to the upper surface of the cylindrical protection device, and the lower layer has a panoramic camera probe welded to the lower surface of the cylindrical protection device. The cylindrical protection device has pre-drilled holes. The acoustic transducer is connected to the signal line of the acoustic monitoring equipment, and the panoramic camera probe is connected to the signal line of the panoramic shooting equipment. The acoustic transducer, through the signal line of the acoustic monitoring equipment, and the panoramic camera probe, through the signal line of the panoramic shooting equipment, are connected to an external artificial intelligence algorithm computer via the pre-drilled holes.

[0013] Furthermore, the ultrasonic testing device refers to the invention patent "A Single-hole Ultrasonic Testing Device and Method for Detecting the Continuity Integrity and Rock Penetration Depth of Concrete Anti-seepage Wall"; the panoramic camera device refers to the journal article "Application Research of Automatic Recognition Technology of Panoramic Drilling Images in Engineering Practice".

[0014] Furthermore, the artificial intelligence algorithm computer has the functions of data storage, geological feature mapping, and iterative calculation of neural network algorithms.

[0015] The beneficial effects of the present invention are as follows: (1) The design of a protective device on the traditional drilling and spraying integrated equipment enables the monitoring-feedback equipment to move with the drilling, thereby enabling accurate exploration of the geological conditions inside and around the hole during the drilling and spraying construction process; (2) The protective device of the present invention can effectively protect the monitoring-feedback equipment. The presence of the spring-telescopic device, the outer metal plate, and the inner high-definition anti-scratch glass allows the monitoring-feedback work to be carried out directly without replacing the equipment after drilling is completed, which greatly improves work efficiency; (3) The artificial intelligence algorithm computer of the present invention is based on the existing database and uses artificial neural network algorithm to continuously optimize the construction control measures. As the amount of data in the database increases, the construction control measures that can be obtained will become more and more accurate, and the application prospects are broad.

[0021] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This invention is implemented as follows: a control system and method for construction based on artificial intelligence algorithms. In this embodiment, taking a water conservancy project's embankment seepage prevention wall as an example, the on-site construction uses integrated drilling and grouting high-pressure jet grouting technology. The preliminary exploration of the strata inside and around the borehole, from top to bottom, are: ① plain fill, ② silty clay, ③ gravelly sand interbedded with silty clay, ④ strongly weathered silty mudstone, and ⑤ slightly weathered silty mudstone. The control system used to guide the high-pressure jet grouting seepage prevention wall construction includes, for example... Figure 1 As shown, it includes: drill bit 1, nozzle 2, panoramic imaging probe 3, acoustic transducer 4, panoramic imaging equipment signal line 5, ultrasonic monitoring equipment signal line 6, cylindrical protective device 7, outer high-strength metal plate 7-1, inner high-definition scratch-resistant glass 7-2, middle partition 7-3, spring-telescopic device 8, rotating paddle 8-1, metal ring 8-2, metal rod 8-3, hard spring 8-4, metal baffle on outer high-strength metal plate 8-5, metal baffle on inner high-definition scratch-resistant glass 8-6, cable 9, high-pressure water pipe 10, grouting pipe 10, gas transmission pipe 12, drill rod 13, artificial intelligence algorithm computer 14, water, gas and slurry mixture 15.

[0023] Furthermore, such as Figure 2 , Figure 3 As shown, the cylindrical protective device has a double-layer structure on its side. The outer layer is a high-strength metal plate, and the inner layer is high-definition scratch-resistant glass. The entire protective device extends into a small portion of the drill rod and drill bit, with the outer high-strength metal plate tightly attached to the inner wall of the drill rod and drill bit. The interior of the cylindrical protective device is divided into upper and lower layers by a middle partition. The upper layer's acoustic transducer is welded to the upper surface of the cylindrical protective device, while the lower layer's panoramic camera probe is welded to the lower surface of the middle partition. The transmission signal line passes through a pre-drilled hole and connects to an external artificial intelligence algorithm computer.

[0024] Furthermore, such as Figure 4 As shown, the outer high-strength metal plate opens and closes vertically via a spring-telescopic device. This device includes a rotating paddle, a metal ring, a metal rod, a rigid spring, and metal baffles. Specifically, a rigid spring is arranged inside the drill rod, close to the drill rod wall. The rigid spring is connected to the outer high-strength metal plate and the top metal ring via a small-diameter metal rod. The metal rod is fixed to the rigid spring and the metal ring by welding. Metal baffles arranged radially are welded to the upper edge of the inner wall of the outer high-strength metal plate and the upper edge of the outer wall of the inner high-definition scratch-resistant glass. A notch is made in the outer wall of the drill rod, through which the rotating paddle is welded to the metal ring. Rotating the rotating paddle causes the metal rod, along with the rigid spring, the outer high-strength metal plate, and the metal baffles, to rotate within the notch area.

[0025] This invention adopts another technical solution, a high-pressure jet grouting anti-seepage wall construction method based on artificial intelligence algorithms, the specific steps of which are as follows:

[0026] Step S1: Determine the design parameters for the high-pressure jet grouting anti-seepage wall construction based on the design data;

[0027] Step S2: Determine the soil and rock parameters and weak interlayer parameters for the borehole layout location based on geological data.

[0028] Step S3: Store the design parameters from step S1 and the parameters of the soil and rock mass and weak interlayer from step S2 into the database.

[0029] Step S4: Call the parameters stored in the database in step S3 to draw the initial geological feature map of the borehole location along the depth direction;

[0030] Step S5: Manually pull the outer high-strength metal plate of the cylindrical protective device to the bottom. Rotate the lever to lock the metal baffle on the outer high-strength metal plate under the metal baffle of the inner high-definition scratch-resistant glass through the tension of the stiff spring, so that the outer high-strength metal plate is in a closed state. Use the drilling and blasting integrated equipment to drill downwards. After the drilling reaches the target depth, rotate the lever to slide out the metal baffle on the high-strength metal plate. Pull up the outer high-strength metal plate through the tension of the stiff spring. Turn on the monitoring-feedback device to start working. Pull up the drill rod so that the monitoring-feedback device inside the cylindrical protective device rises slowly with the drill rod and stores the collected data information in the database.

[0031] Step S6: Based on the data information collected in step S5, draw a new geological feature map in the computer again. Based on the initial geological feature map, manually adjust it to obtain the final geological feature map, and store the adjusted final data in the database.

[0032] Step S7: Based on the parameter information in the database, a neural network algorithm is used to continuously iterate and calculate the basic design information, monitoring feedback information, and construction control measures information. The integrity and impermeability strength of the core sample obtained from the core sampling test are used as the judgment criteria to obtain the optimal construction control measures and control the jet grouting construction.

[0033] Furthermore, the design parameters for step S1 include the borehole diameter, borehole depth, borehole spacing, and drill rod and nozzle dimensions of the integrated drilling and blasting equipment for the high-pressure jet grouting anti-seepage wall construction.

[0034] Furthermore, the soil and rock mass parameters in step S2 include the layer thickness, dip angle with the horizontal plane, elastic modulus, and Poisson's ratio of the soil and rock mass, and the weak interlayer parameters include the thickness of the weak interlayer, dip angle with the horizontal plane, and strength parameters of the weak interlayer layer.

[0035] Furthermore, the database in step S3 is used to store various parameter information of each high-pressure jet grouting anti-seepage wall construction, including basic design information, monitoring feedback information, construction control measures information and construction quality information, so as to facilitate data retrieval for iterative calculation by the neural network algorithm.

[0036] Furthermore, the new geological feature map in step S6 is drawn based on the data collected through acoustic wave analysis and image recognition. Acoustic wave analysis determines the distribution and strength of the surrounding rock and soil mass and weak interlayers by analyzing the relationship between ultrasonic sound pressure values ​​and the acoustic impedance information of the borehole surrounding medium. Image recognition uses a method based on clustering projection and feature function matching to identify each panoramic borehole image, obtaining parameters such as the width and dip angle of the weak interlayers in the borehole wall. The collected parameter information is then used to create the geological feature map.

[0037] Furthermore, the manual adjustment in step S6 is based on the initial geological feature map and various parameter information collected by ultrasonic analysis and image recognition. The focus is on adjusting the distribution, width and dip angle of weak interlayers, removing weak interlayers with smaller areas, merging weak interlayers with closer distances, and avoiding frequent changes in the jetting speed and nozzle angle in a short period of time.

[0038] Furthermore, the basic design information in step S7 includes: aperture d, hole depth h, and hole spacing s; the monitoring feedback information includes: the thickness H of the weak interlayer and the inclination angle of the weak interlayer to the horizontal plane. The elastic modulus E and Poisson's ratio μ of the soil and rock mass; construction control measures include: adjusting the jetting lifting speed v, adjusting the nozzle grouting pressure P, adjusting the nozzle angle φ, and adjusting the grout concentration c.

[0039] Furthermore, the neural network iterative calculation in step S7 is based on the BP neural network algorithm. It uses the basic design and monitoring feedback information from the existing database as input, and utilizes the activation function to output the final construction control measures information. The integrity and impermeability strength of the core samples are used as the judgment criteria. If the core sample does not meet the integrity and impermeability strength requirements, the weight coefficients are readjusted according to the gradient descent method for the next iteration calculation. If the core sample meets the integrity and impermeability strength requirements, the weight coefficients do not need to be adjusted and it is directly used for the next iteration calculation. Theoretically, the larger the database available for the system to learn from, the higher the accuracy of the obtained jet grouting control measures.

[0040] This invention utilizes feedback data from ultrasonic devices and panoramic cameras, which, after manual adjustment, yields a detailed geological feature map of the borehole and its surrounding area. This map includes the thickness, dip angle, strength, and details of weak interlayers within each stratum. For example, in a soft-over-hard stratum, the system determines the thickness, dip angle, and strength of each stratum, delineates the structural boundary between soft and hard strata, marks the location and size of weak interlayers, and calculates the impact of the weak interlayers on the original strata. This allows for precise control measures to ensure the geyser reaches the target location.
