Technical Field

[0001] The invention belongs to the technical field of tunnel and underground engineering grouting, and in particular relates to a method and system for quickly detecting the diffusion range of slurry based on magnetic tracer materials. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Grouting technology is widely used in the prevention and control of rock and soil engineering disasters, and is often used for reinforcement and leakage channel blocking in the construction of mining, transportation, water conservancy and other projects. The diffusion and reinforcement effect of rock and soil grouting is a key link in determining engineering safety. However, rock and soil grouting is hidden and difficult to predict. Especially in large-scale grouting, the uncontrollability and unknowability of the slurry diffusion area increase engineering risks.

[0004] Among the existing grouting effect evaluation methods: drilling methods have a limited detection range and lag; parameter analysis methods rely on empirical judgment and are not suitable for complex formations; geophysical methods such as geological radar and acoustic surveys have a very limited detection distance and it is difficult to achieve high-precision distinction between grouting bodies and natural rock masses. Summary of the invention

[0005] In order to solve at least one technical problem existing in the above-mentioned background technology, the present invention provides a method and system for quickly detecting the diffusion range of slurry based on magnetic tracer materials. By adding magnetic tracer materials to the slurry and combining them with aerial magnetic survey methods, the method can realize the rapid detection of the diffusion range of slurry in formation grouting reconstruction projects and improve the efficiency of grouting effect evaluation.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] The first aspect of the present invention provides a method for quickly detecting the diffusion range of a slurry based on a magnetic tracer material, comprising the following steps:

[0008] Draw the magnetic field distribution map of the target area before grouting based on the determined magnetic field detection line;

[0009] Based on the same magnetic field detection line, draw the magnetic field distribution map of the target area after grouting where the magnetic slurry containing magnetic tracer material is injected;

[0010] According to the magnetic field distribution map before grouting and the magnetic field distribution map after grouting in the target area, the abnormal magnetic field distribution characteristics are calculated;

[0011] Based on the obtained magnetic susceptibility and magnetic field response characteristics of the magnetic grouting body after grouting, the distribution range of the underground magnetic grouting body is inverted and the magnetic grouting body formation model is drawn;

[0012] The magnetic grouting body formation model is modified based on the obtained abnormal magnetic field distribution characteristics to obtain the distribution range of the magnetic grouting body.

[0013] Furthermore, the preparation process of the magnetic slurry containing the magnetic tracer material includes:

[0021] Furthermore, the magnetic field response characteristics include the influence of the shape, size, and thickness of the grouting body on the geomagnetic field response, and the law of change of the measured coupled magnetic field characteristic parameters with the distance from the detection point.

[0022] Furthermore, according to the magnetic field distribution map before grouting and the magnetic field distribution map after grouting in the target area, the abnormal magnetic field distribution characteristics are calculated, including:

[0045] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0047] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0048] As mentioned in the background technology, the existing grouting effect evaluation methods: drilling methods have limited detection range and lag; parameter analysis methods rely on experience and judgment, and are not applicable to complex formations; geophysical methods such as geological radar and sonic surveys have very limited detection distances, and it is difficult to achieve high-precision distinction between grouting bodies and natural rock bodies. Therefore, there is an urgent need for a new method that can quickly and non-destructively detect the diffusion range of grouting bodies and evaluate grouting effects.

[0049] The present invention avoids the traditional drilling detection process by adding magnetic tracer materials to the slurry and combining the aeromagnetic method, greatly reduces the construction cost, realizes the rapid detection of the slurry diffusion range in the formation grouting reconstruction project, and improves the efficiency of grouting effect evaluation.

[0050] Embodiment 1

[0051] like Figure 1 As shown, this embodiment provides a method for quickly detecting the diffusion range of slurry based on magnetic tracer materials, comprising the following steps:

[0052] Step 1: Draw a magnetic field distribution map of the target area before grouting based on the determined magnetic field detection line;

[0053] Among them, the magnetic field detection line is set according to the formation characteristics of the target area to be grouting;

[0054] In this embodiment, the setting standard of the magnetic field detection line is:

[0055] The survey line covers an area that completely includes the grouting target area and covers an area that is more than twice the area of ​​the target area; three groups of survey lines at different levels are set at intervals of 5m, and all measuring points on the same plane are maintained at a fixed horizontal height.

[0056] In this embodiment, the drawn magnetic field distribution map includes a magnetic field profile plane map, a magnetic field contour line plane map, a typical anomaly comprehensive profile map, and the like.

[0057] The aerial magnetic field detection line diagram of this embodiment is as follows Figure 2 As shown, the aerial magnetic field detection device 1 is used to detect the magnetic field of the target area along a fixed survey line to draw a magnetic field distribution map.

[0058] Step 2: Based on the same magnetic field detection line, draw a post-grouting magnetic field distribution map of the target area where the magnetic slurry containing the magnetic tracer material is injected;

[0059] In this embodiment, when drawing the magnetic field distribution map after grouting, the detection area and the measurement line are consistent with the magnetic field distribution map before grouting;

[0060] like Figure 3 The figure shows the magnetic slurry injection process. When injecting magnetic slurry containing magnetic tracer material, it includes:

[0061] Step 201: According to the construction requirements of the project and the stratigraphic characteristics of the target area obtained in the previous geophysical exploration, Figure 3 The middle reformed stratum 3 is the target area stratum, 2 is the overlying stratum, and then the grouting range and grouting points are determined;

[0062] Step 202, drilling a hole at the grouting point and installing a grouting pipe 4, wherein the material of the grouting pipe is required to be a non-magnetic material so as not to affect the distribution of internal magnetic particles during the flow of the magnetic slurry;

[0063] Step 203 : Inject the prepared magnetic slurry into the target area 5 through the assembled pumping unit.

[0064] In this embodiment, the preparation process of the magnetic slurry includes:

[0065] Step 2031: Determine the flow performance requirements, magnetic particle size requirements, magnetic susceptibility requirements and mechanical performance requirements of the magnetic slurry according to the measured geomagnetic field strength, formation lithology characteristics and formation pore and fracture size distribution characteristics;

[0066] Step 2032: according to the performance requirements of the magnetic slurry, determine the type and particle size of the magnetic particles in the magnetic tracer material, the types include: nano iron oxide (Fe2O3) particles, iron oxide (Fe3O4) particles, iron oxide and manganese composite (Fe3O4&Mn) particles, iron oxide and cobalt composite (Fe3O4&Co) particles, and the particle sizes corresponding to each type of particles include: 100-200nm, 200-400nm, 400-1μm, 1μm-3μm, 3μm-5μm;

[0067] Step 2033: After determining the type and particle size of the magnetic particles, the magnetism of the particles is enhanced by optimizing the crystal structure and applying an external strong magnetic field treatment;

[0068] Step 2034, an orthogonal design experiment is performed with the weight ratio of magnetic particles to cement, the water-cement ratio, the amount of water reducing agent added, and the amount of surfactant added as influencing factors. The weight ratio of magnetic particles to cement includes 1:9, 2:8, 3:7, 4:6, and 5:5, and the water-cement ratio includes 0.7, 1.4, and 2.1. The ratio with the highest magnetic slurry magnetic susceptibility and meeting the formation flow requirements is the best ratio.

[0069] Step 2035, weighing each raw material according to the optimal ratio determined in step 2034, and after completion, first mixing the magnetic particles with cement and stirring, and then adding water, a water reducing agent and a surfactant and continuing to stir, and after stirring evenly, the magnetic slurry is prepared;

[0070] Step 2036, testing the magnetic field response characteristics of the magnetic grouting body generated after the prepared magnetic slurry solidifies, wherein the magnetic field response characteristics refer to the coupled magnetic field characteristics exhibited by the interaction between the magnetic field generated by the magnetic grouting body and the geomagnetic field, including the influence of the shape, size, and thickness of the grouting body on the geomagnetic field response, and the law of change of the measured coupled magnetic field characteristic parameters with the distance from the detection point.

[0071] The above scheme introduces magnetic tracer materials to make the slurry stone body have physical properties that are clearly distinguishable from natural stratum rock bodies. During the inversion process, the signal has specificity, which can improve the accuracy of the inversion results.

[0072] Step 3: Calculate the abnormal magnetic field distribution characteristics based on the difference between the magnetic field distribution map before grouting and the magnetic field distribution map after grouting in the target area;

[0073] After obtaining the magnetic field distribution map before grouting and the magnetic field distribution map after grouting in the target area, the data processing includes:

[0074] Step 301, performing noise reduction processing on the magnetic field distribution map before grouting and the magnetic field distribution map after grouting in the target area to remove noise signals;

[0075] Step 302, taking the part of the magnetic field distribution diagram before grouting and the magnetic field distribution diagram after grouting where the magnetic field characteristic change is less than 5% as the baseline, calibrating the magnetic field before and after grouting, and overlapping the magnetic field distribution lines before and after grouting;

[0076] Step 303: Analyze the overlapped magnetic field distribution map, and subtract the magnetic field distribution map before grouting from the magnetic field distribution map after grouting to obtain abnormal magnetic field distribution characteristics.

[0077] Step 4: Based on the obtained magnetic susceptibility and magnetic field response characteristics of the magnetic grouting body after grouting, the distribution range of the underground magnetic grouting body is inverted and a magnetic grouting body formation model is drawn;

[0078] In this embodiment, the magnetic susceptibility and magnetic field response characteristics of the magnetic grouting body are obtained based on the test after the magnetic slurry solidifies, wherein the magnetic field response characteristics refer to the coupled magnetic field characteristics exhibited by the interaction between the magnetic field generated by the magnetic grouting body and the geomagnetic field, including the influence of the shape, size and thickness of the grouting body on the geomagnetic field response, and the law of change of the measured coupled magnetic field characteristic parameters with the distance from the detection point.

[0079] Step 5: Modify the magnetic grouting body formation model according to the abnormal magnetic field distribution characteristics to obtain the magnetic grouting body distribution range;

[0080] In this embodiment, according to the abnormal magnetic field distribution map, drilling is carried out toward the edge of the abnormal magnetic field and the weak magnetic area, and the formation model is corrected according to whether the magnetic grouting body is drilled in the drilling hole to obtain the accurate distribution range of the magnetic grouting body;

[0081] Step 6: Evaluate the grouting effect according to the distribution range of the obtained magnetic grouting body;

[0082] In this embodiment, the grouting effect evaluation standard is: if the coverage rate of the distribution range of the magnetic grouting body in the target transformation area reaches more than 80%, the grouting effect is good, and if the coverage rate is less than 80%, the grouting effect is poor.

[0083] Through the above scheme, the use of aerial magnetic field detection and non-invasive monitoring methods avoids the traditional drilling detection process, greatly reduces construction costs, and can complete the effect evaluation in a short period of time after grouting. At the same time, it can achieve long-distance and comprehensive exploration of the slurry diffusion range in the formation. The detection signal is not affected by water bodies, structures, etc., and the slurry identification accuracy is high and the spatial positioning is accurate, especially in the evaluation of large-scale grouting effects. The advantages are more obvious.
