Description

TECHNICAL FIELD

[0001] The utility model relates to tunnel advanced prediction elastic wave detection technical field especially relates to a seismic wave method tunnel advanced prediction acceleration probe jacking device. BACKGROUND

[0002] In the tunnel construction process, due to the certain limitation of ground geological exploration in the early construction, it is difficult to have a comprehensive and accurate grasp of the regional engineering geological conditions, and the adverse geological bodies such as faults, fracture zones and karst water bodies are the main disaster occurrence sources in the tunnel excavation process, which may induce geological disasters such as collapse, water and mud inrush under the construction disturbance, causing serious life and property losses to the tunnel construction, so it is necessary to track and detect the tunnel advanced direction geological conditions in the tunnel construction process. At present, the tunnel advanced detection methods include four types of geological analysis method, advanced pilot tunnel method, drilling method and geophysical detection method. The geological analysis method is the most basic prediction method, which comprehensively analyzes the surface detailed investigation and tunnel internal geological sketch, advanced blast hole, water inflow and other data, understands the geological conditions of the tunnel, and uses the geological theory to compare, demonstrate, deduce and predict the engineering geology and hydrogeology conditions in front of the tunnel face, the advanced pilot tunnel method has a larger excavation section, which can comprehensively reveal the geological conditions in front of the tunnel face, but it takes a long time and costs high, and is generally used only in the construction of extremely high ground stress and soft rock tunnel. The drilling method has high accuracy, but its construction is complex, the cost is too high, and the detection result is "one hole", which only accurately grasps the geological conditions in a small range around the drilling hole. The geophysical detection method is necessary for the actual engineering due to its convenient construction, low cost and large detection area, and the seismic advanced detection is the most important geophysical method in tunnel advanced detection due to its sensitivity to the velocity and density of geological medium and high resolution.

[0003] In petroleum seismic exploration, the geophone is often vertically buried in the surface soil layer, and the friction of the soil layer on the geophone and the gravity of the geophone itself are coupled. In tunnel seismic exploration, the geophone is arranged in the tunnel, and the sensor is generally arranged on the hard two-side rock wall. The TRT system directly uses quick-drying cement to paste the sensor on the tunnel wall, and the data collected by this acquisition mode is easily interfered by strong sound waves and surface waves; at the same time, due to the failure to effectively avoid the influence of the tunnel peripheral relaxation zone caused by the tunnel excavation disturbance, the quality of the finally obtained data is reduced.

[0004] The acquisition mode of TSP, TGP and TST systems is to drill a 1.5-2m deep hole in the tunnel side wall first, and then arrange the sensor in the hole to receive the seismic signal. This mode effectively avoids the interference of sound waves and surface waves, and also avoids the influence of the low-speed area of the tunnel relaxation zone on the data quality. However, how to ensure that the sensor and the drilling hole are tightly coupled and easy to recycle and reuse has become a major challenge faced by the engineering site.

[0005] The TSP system installs the sensor into a special sleeve, and then installs the sleeve into the borehole and couples it with anchoring agent, which is complex in field operation, low in efficiency, high in cost, and forms a cavity gap interface between the sleeve and the rock wall, which has great influence on the amplitude and frequency of seismic data, and there is currently a lack of quantitative research and compensation measures, and the more serious problem is that the sensor and the sleeve are not closely attached together for the convenience of implanting and taking out the sensor in the sleeve, which directly leads to the loss of a large amount of high-frequency signals of seismic data. The TGP and TST systems inject butter into the borehole, and then implant the geophone in the butter, which not only forms a gap interface, but also has a very small shear modulus of the butter medium, which has a great influence on the attenuation of the shear wave, and in the frequency domain, the quality factor of the butter is small, and the high-frequency attenuation of the P-S wave signal is serious. Some people also try to put the sensor in an air bag and put them into the borehole together, and then inflate the air bag to couple it, but this also faces the same problem as the butter coupling, and the influence is more serious. All the above coupling methods have a common problem, that is, it takes a long time to bury the sensor in the field, and the TSP system needs to bury the sleeve first, the TGP and TST need to push the butter into the borehole first, and the air bag sensor needs to be inflated in the field. Like shooting, these work will also affect the tunneling construction flow operation, so generally only two sensors are set, which leads to less original data and affects the detection effect. The current common coupling methods all have theoretical problems, and in engineering practice, data acquisition failure is often caused by poor coupling conditions, and the coupling problem is always easily ignored but crucial in tunnel seismic exploration. Therefore, how to ensure the coupling quality during construction is the key, and under the premise of ensuring the coupling quality, high-precision wide-band sensors can collect high signal-to-noise ratio original data to ensure the effect of advanced detection.
