Description

Technical Field

[0001] The present invention relates to a technical field, and in particular to a deep hole test data acquisition device and a hole body material selection method based on the deep hole test. Background Art

[0002] At present, with the construction of high-head water conservancy and hydropower projects, high-head flood discharge deep holes are widely used in dam body flood discharge systems, and they undertake huge flood discharge tasks. The design shape of the flood discharge not only needs to ensure the safety of its own structure, but also needs to consider the impact of flood discharge on downstream stability. Due to various restrictions on the space of the high arch dam body, the deep hole inlet and the deep hole outlet are often unable to be in the same straight line. Therefore, there may be a certain deflection angle of the deep hole in the dam body. For the sake of downstream safety, the landing points of the deep hole discharge tongue are required to be dispersed in space, which requires that the deep hole outlet must use a certain lifting or downward pressing composite shape. Various factors lead to the complexity of the deep hole hydraulic problem. Due to the gradual change of the deep hole body shape, especially the longitudinal compression of the outlet, the water flow at the deep hole outlet has a large lateral diffusion angle. When the distance between the side piers is insufficient, the lateral diffusion water flow impacts the side piers, which easily causes the side pier structure to become unstable.

[0003] During the deep hole construction process, in order to protect the deep hole and prevent it from being deformed by running water, protective building materials are usually applied on the hole wall of the deep hole.

[0004] In the Chinese invention with publication number CN106836154A, a "new deep hole with the function of reducing the lateral diffusion of outlet water flow" is disclosed, including a deep hole model with an emergency valve, a maintenance valve and a transverse seam, the deep hole model includes an inlet, a hole body and an outlet, and side piers are arranged on both sides of the outlet. The inlet section and the outlet section of the deep hole model are both rectangular, the vertical height of the inlet section is higher than the vertical height of the outlet section, and the deviation of the vertical height does not exceed 35%, and the lateral width of the inlet section is smaller than the lateral width of the outlet section. It has a more reasonable shape and is suitable for deep holes with different sizes of inlet and outlet sections. At the same time, it can greatly reduce the lateral diffusion of outlet water flow, prevent water flow from impacting the side piers, and effectively protect the structural stability of the deep hole outlet side piers.

[0005] Although the above invention provides a practical and effective design scheme for the excavation and construction of deep holes, in the actual working process, due to the overly complex underground water veins, the temperature, pH, amount of entrained sediment and water flow velocity of water flows in different places are different. The above factors will cause different degrees of erosion to the same deep hole construction. Severe erosion may even cause destructive deformation of the deep hole, leading to failure of the deep hole. Building materials of too good quality also have the problem of high cost. In some areas where water erosion is weak, the use of building materials of better quality will also result in waste. Summary of the invention

[0006] The purpose of the present invention is to address the defects of the prior art and provide a deep hole test data acquisition device and a method for selecting materials for the hole body based on the deep hole test, which can realize the establishment of a construction-level groundwater vein model to assist technical personnel in deep hole construction to quickly simulate the water flow conditions of the groundwater veins in the construction area, conduct rapid scouring experiments on building materials used for deep hole construction, and inspect the actual use of building materials.

[0041] Embodiment 1:

[0042] See also Figure 1A new type of deep hole test and data acquisition system includes a deep hole model with an emergency valve 1002, a maintenance valve 1001 and a transverse seam 1003. The deep hole is suitable for deep holes with different cross-sectional sizes between the inlet 111 and the outlet 114. At the same time, it can greatly reduce the lateral diffusion 110 of the water flow at the outlet 114, prevent the water flow from impacting the side pier, and effectively protect the structural stability of the side pier at the deep hole outlet 114. The deep hole model includes an inlet 111, a tunnel body and an outlet 114. Side piers are arranged on both sides of the outlet 114. The tunnel body includes a front section 112 and a rear section 113. A deep hole plane deflection starting point is arranged between the front section and the rear section, and a transverse diffusion 110 is arranged between the front section 112 and the rear section 113. Among them, the deep hole plane deflection starting point is the turning point between the front section 112 and the rear section 113. The lateral diffuser 110 is a diffuser tubular structure with a small front end diameter and a large rear end diameter, and is used to connect a deep hole front section 112 with a smaller diameter and a deep hole rear section 113 with a larger diameter.

[0043] like Figure 1 As shown, a detection device 201 is fixedly connected in the front section 112, the detection device 2 includes a detection device mounting base 3, and the detection device 2 is fixedly connected to the inner wall of the front section 112 through the detection device mounting base 3, the detection device mounting base 3 is fixedly connected to a Hall magnetic flow guide pipe fixing ring 4, and a Hall magnetic flow guide pipe 5 is inserted in the Hall magnetic flow guide pipe fixing ring 4, and the Hall magnetic flow guide pipe 5 includes a main body 501. The inner wall of the main body 501 is fixedly connected to a detection tube body 502, and the detection tube body 502 is a building material for protecting the deep hole during the deep hole construction process. The inner wall of the detection tube body 502 is an inspection layer. A detection terminal 6 is provided in the Hall magnetic flow guide pipe 5. The detection device 202 is arranged at the starting point of the deep hole plane deflection, and the detection device 202 is fixedly connected to the inner wall of the lateral diffuser 110, which is used to measure the water pressure and water flow velocity of the detection device 202. The detection device 203 is arranged at the outlet 114, and the detection device 203 is fixedly connected to the inner wall of the outlet 114. The detection device 203 is arranged at the outlet 114, and the detection device 203 is fixedly connected to the inner wall of the outlet 114. A compensating rubber ring is sleeved on the outer wall of the detection device 2, and the thickness of the compensating rubber ring matches the diameter of the deep hole where the detection device 2 is located, so as to achieve the sealing between the outer wall of the detection device 2 and the inner wall of the deep hole. The sealing between the detection device 2 and the inner wall of the deep hole is increased, so that the water flow is not easy to seep out from between the detection device 2 and the inner wall of the deep hole, and it is not easy to affect the measurement accuracy of the detection device 2. During the measurement process, the detection device 2 at the front section 112, the starting point of the deep hole plane deflection and the outlet 114 needs to be measured separately in three tests to avoid the detection device 2 located upstream from causing too much influence on the water flow and causing a large measurement error of the detection device 2 located downstream.

[0044] like Figure 7As shown, the detection terminal 6 is electrically connected to the single-chip computer body 7, the single-chip computer body 7 is respectively connected to the display terminal 8 and the control panel 9, the single-chip computer body 7 is signal-connected to the cloud storage 10, and the data measured by the single-chip computer body 7 can be uploaded to the cloud storage 10 and stored, which can be used for deep hole construction technicians in other regions to review and compare. After a long period of data accumulation and reserve, the test preparation cost of deep hole construction technicians before design can be effectively reduced.

[0045] like Figure 4-6 As shown, the detection terminal 6 includes a thin film pressure sensor 601 and a Hall sensor 602. The thin film pressure sensor 601 is fixedly connected to the inner wall of the detection tube body 502, and the Hall sensor 602 is fixedly connected to the main body 501, and the Hall sensor 602 penetrates the detection tube body 502 and extends to the outside of the detection tube body 502. The thin film pressure sensor 601 is used to measure water pressure, and the Hall sensor 602 is used to measure water flow velocity. The contact surface between the thin film pressure sensor 601 and the detection tube body 502 is a smooth curved surface, which reduces the resistance of the thin film pressure sensor 601 to the water flow and reduces the measurement error. The inner wall of the main body 501 is fixedly connected with a rotating shaft, and a counting impeller 603 matching the Hall sensor 602 is sleeved on the rotating shaft. The counting impeller 603 is used to assist the Hall sensor 602 in measuring the water flow velocity in the Hall magnetic guide pipe 5. The inner wall of the detection tube body 502 is fixedly connected with a polishing layer to reduce the friction between the inner wall 520 and the water flow, so that the inner wall of the detection tube body 502 is not eroded by the flowing water.

[0046] A neutral marker liquid is added to the flowing water used for measurement. After the measurement is completed, the neutral marker liquid remaining on the inner wall of the detection tube body 502 can clearly mark the scratches on the inner wall of the detection tube body 502, so that the staff can intuitively observe the damage condition of the detection tube body 502.

[0047] When it is necessary to conduct a simulation test on the deep hole construction, a plurality of corresponding deep hole models and a detection device 2 including a detection tube body 502 of different materials are prepared in advance to prepare for the subsequent comparative test. When it is necessary to conduct a measurement, the detection device 2 is respectively set at the front section 112, the starting point of the deep hole plane deflection and the outlet 114 of the three different deep hole models, and simulated water is put into the deep hole from the inlet 111. In particular, the simulated water needs to be set according to the groundwater conditions of the deep hole groundwater vein. The simulated water is located at the front section 112, the deep hole plane deflection starting point and the outlet 114 because the water temperature, pH value and the amount of mud mixed in the water are roughly the same as those of the groundwater conditions. The detection device 2 at the starting point of the hole plane deflection and the outlet 114 can respectively measure the wear of the detection tube body 502 caused by the water flow. After the test is completed, the detection device 2 can be taken out of the deep hole, and the technician can smoothly observe the degree of wear of the detection tube body 502. Thereafter, the detection device 2 containing the detection tube body 502 of different materials is placed in the front section 112, the starting point of the deep hole plane deflection and the outlet 114 of a new set of deep hole models, and the above test is repeated to obtain the new degree of wear of the detection tube body 502. The above test is continued until the detection tube bodies 502 containing different materials have completed the test.

[0048] Through multiple groups of comparative tests, the staff can clearly know the degree of wear of the detection tube body 502 made of different materials in the deep hole. The technicians can select the appropriate construction materials required for the front section 112, the starting point of the deep hole plane deflection and the exit 114 during the deep hole construction process according to the designed service life of the deep hole and the budget of the deep hole construction, which can greatly reduce the cost of deep hole construction and improve the quality of deep hole construction.

[0049] Embodiment 2:

[0050] like Figure 8 The method flow for selecting materials for deep hole body based on deep hole test shown in the figure includes:

[0051] A deep hole model and multiple detection devices 2 are constructed, and simulated water is configured. The detection device has a replaceable detection tube body 502 for the simulated water to pass through and a detection terminal 6 arranged inside the detection tube body 502. The simulated water is set according to the groundwater conditions of the deep hole groundwater vein, and neutral marker liquid is added to the simulated water. The multiple detection tube bodies 502 are divided into three groups, each group is exactly the same, and each group of detection tube bodies 502 is made of different building materials;

[0052] After the detection device 2 is sealed and fixed axially at any detection position among the front section 112 of the tunnel body, the outlet 114 and the starting point of the deep hole plane deflection, simulated water is released into the tunnel body from the inlet of the deep hole model to perform a simulated water flushing test;

[0053] Read the data collected by the detection terminal 6 in real time, remove the detection tube body 502 after the calibration time, obtain the wear degree data of the inner wall of the detection tube body 502, and store the wear degree data and the data collected by the detection terminal 6 as a set of test data of the current detection position;

[0054] The different detection tube bodies 502 are replaced in sequence, and the simulated water flushing test is repeated at the detection position to obtain the remaining multiple groups of test data at the detection position, until all the detection tube bodies 502 of all materials in the group of detection tube bodies 502 are tested;

[0055] Carry out the simulated water flushing test at the other two test positions respectively in the same steps until the simulated water flushing test at the three test positions is completed;

[0056] The correlation between the degree of wear of water flow and building materials is obtained based on multiple groups of test data at each detection position, and the building materials for the front section 112 of the tunnel body, the outlet 114 and the starting point of the deep hole plane deflection are selected according to the water flow conditions and the correlation of each detection position.
