Description

Technical Field

[0001] The invention relates to the technical field of experimental devices and application methods, in particular to a grouting test device in a simulated corrosion environment and an application method thereof. Background Art

[0002] In existing engineering construction, grouting operations are often involved. During the specific work, the grouting slurry (such as concrete slurry) is injected into the corresponding parts (such as the grouting reinforcement parts under the ground around the bridge piers, to reinforce the bridge piers, etc. During the specific construction, the corresponding amount of stones of corresponding sizes will be injected into the corresponding parts after drilling in advance, and the slurry will enter between several stones and form a concrete foundation after solidification). In actual situations, whether the corresponding parts contain excessive corrosive ions (such as alkaline substances) will affect the quality after grouting. The speed and pressure of the grouting pump can affect the diffusion speed of the slurry, the grouting range, the density of the grouting, etc.; further, if the corrosive ions in the grouting part exceed the abnormality, ordinary concrete slurry is used for grouting, then due to the subsequent corrosion, the safety of concrete components such as bridge piers cannot be guaranteed. Correspondingly, the grouting speed and diffusion speed of the grouting pump are too slow, the pressure is too low, etc., which will affect the work efficiency and quality of grouting. Specifically, for example, if the grouting speed and diffusion speed are too slow, it may be that the power of the grouting pump is insufficient, or the viscosity of the slurry is too high (the above will cause the slurry to be unable to effectively fill the interior of the grouting area, and thus cannot effectively ensure the safety of the component); on the contrary, if the grouting speed and diffusion speed are too fast, it may be that the power of the grouting pump is too large, or the viscosity of the slurry is too low (the above will cause the slurry to fill the grouting area and dry, resulting in cavities in the concrete, and similarly, cannot effectively ensure the safety of the component).

[0003] In the prior art, in order to prevent the corrosive ions contained in the grouting part from threatening the quality of the corresponding structure, a drilling sampling process is used to take out soil samples or rock samples from the corresponding part, and then the corresponding concrete slurry containing different ingredients (to reduce the corrosive effect of corrosive ions, etc.) is equipped for grouting in the subsequent construction, which guarantees the safety of the corresponding structure after grouting to a certain extent. Although the above construction method satisfies the safety grouting of the corresponding parts of the structure to a certain extent, due to the limitation of the technical solution, its shortcomings are also obvious. The specific shortcomings are as follows. First, it is impossible to actually understand the quality of the slurry after grouting and the corresponding part, and it is impossible to understand the diffusion, grouting speed and solidification state of the slurry with the corresponding concentration and corresponding ingredients under the corresponding power of the grouting pump at different pressures, and it is impossible to provide more theoretical data support for actual operations. That is to say, after the actual construction, it will more or less have an adverse effect on the safety of the corresponding structure. Second: For the engineering party, especially the construction party, they have no idea about the relevant grouting operation data. That is to say, when the construction party fails to meet the grouting standards for the corresponding parts of the relevant areas, the engineering party is unaware. Even if there are problems with the grouting operation of the structure, they cannot make reasonable rectification suggestions due to the lack of relevant data. Since they cannot guarantee the safety of the corresponding structure, they cannot guarantee their own rights and interests. In summary, it is very necessary to provide a grouting test device and its application method that can simulate the conditions of different slurry concentrations, different pressures of grouting pumps, different corrosive ions (different temperatures), etc., to obtain the diffusion rate, diffusion pressure, and quality of the slurry after solidification, and the engineering party can understand various data in real time, so as to provide data support for subsequent staff to supervise the grouting construction quality of the construction party on site. Summary of the invention

[0004] In order to overcome the disadvantages in the prior art that there is no suitable equipment for simulating different concentrations of slurry, different pressures of grouting pumps, different corrosive ions and other conditions to obtain data such as diffusion rate, diffusion pressure, and quality of slurry after solidification, and that the engineering party cannot understand various grouting data and cannot provide technical support for on-site staff to supervise the grouting construction quality, the present invention provides a grouting test device and an application method for simulating corrosion environment under the joint action of relevant mechanisms and software units, so that the construction party can conveniently conduct experiments on data such as diffusion rate, diffusion pressure, and quality of slurry after solidification based on conditions such as different concentrations of slurry, different pressures of grouting pumps, and different corrosive ion water concentrations (different temperatures), and obtain data after slurry solidification, and various data can be transmitted wirelessly, so that the construction party and engineering party technical personnel can understand in real time whether the experimental data is qualified, so that subsequent relevant engineering party personnel can effectively supervise various grouting data of the construction party on site, and provide favorable technical support for ensuring the safety of corresponding structures.

[0018] Figure 1 , 2As shown in, an application method of a grouting test device in a simulated corrosion environment includes the following steps: (1): the experimenter places concrete medium materials such as stones of different sizes from top to bottom in the hollow steel barrel 10 of the grouting test in advance. (2): the PLC controls the grouting pump 4 to work for a period of time to extract the concrete slurry in the slurry storage barrel 1 and pressurize it into the hollow steel barrel 10 of the grouting test, and controls the water injection pump 28 to work for a period of time to extract the water and corrosive ion water mixture in the water storage barrel into the hollow steel barrel 10 of the grouting test; specifically, by controlling the time of concrete slurry and the time (and concentration) of the water and corrosive ion water mixture input into the hollow steel barrel 10 of the grouting test, it can simulate the concrete slurry and the water and corrosive ion water mixture with different concentrations, and the concrete slurry and the water and corrosive ion water mixture with different ratios, and the corresponding concrete block samples after subsequent solidification. Used for various physical and chemical tests; specifically, when the ion monitoring-adding integrated machine 30 monitoring system detects that the water and ion liquid concentration data are too high or too low through the matching detection head 46, the signal output end of the monitoring system will output a relatively low or relatively high voltage signal to the electric proportional valve according to the threshold value set by the technician. The valve core of the electric proportional valve is closed or opened, so that the ion liquid in the box can enter the water to reach the set ratio. The PLC can control the working time mode of the heating rod 32, so that the water temperature entering the hollow steel barrel 10 of the grouting test reaches different temperatures (different temperatures can affect the concrete construction performance after the slurry solidifies). (3): PLC controls the piston rod of the jack 19 to move downward, through the top steel plate 18, to compress the slurry in the hollow steel barrel 10 of the grouting test, and to discharge the air in the slurry (the exhaust hole 15 discharges the air in the slurry): Specifically, when the piston rod of the hydraulic jack 19 is controlled by PLC to drive the top steel plate 18 to compress the slurry, the hydraulic jack can be stopped when the pressure data monitored by the strain gauge 12 is higher than the set pressure threshold of the PLC, so that the jack is at the pressure tonnage set in the test and remains constant (after the top steel plate 18 contacts the upper end of the slurry, the jack can be controlled to stop working to prevent the slurry from overflowing from the exhaust hole 15).(4): During the experiment, the grouting pressure transmitter 5 collects the grouting pressure data of the grouting pump 4 in real time, the strain gauge 12 collects the pressure data in the hollow steel barrel 10 of the grouting test in real time, the temperature sensor 13 collects the temperature data in the hollow steel barrel 10 of the grouting test in real time, the wave velocity transmitter 14 and the wave velocity receiver 20 (such as HS-YT302R1, RSM-SW(A), ZT series, WAVE3000, PDS-SV, BD56-XG-I, etc.) collect the diffusion range data of the slurry in the hollow steel barrel 10 of the grouting test after solidification in real time, and the control system of the ion monitoring-adding integrated machine 30 The water and ionic liquid concentration data in the water storage tank 38 are collected in real time, and the above-mentioned multiple data are output to the 5G data transmission module 41 and the multi-channel signal input terminal of the data processing computer 24 (the above-mentioned data are output to the data processing computer 20 for real-time display), and the data output by the grouting pressure transmitter 5 and the dynamic water pressure sensor 27 enter the two-channel signal input terminal of the PLC. Specifically, when the pressure data output by the grouting pump 4 and the water injection pump 28 are respectively greater than the set threshold values ​​inside them, the PLC can temporarily control the grouting pump 4 and the water injection pump 28 to lose power and stop working, so as to prevent the grouting pump 4 and the water injection pump 28 from being damaged due to blockage. (5): The data receiving unit receives the grouting pressure data monitored by the grouting pressure transmitter 5, the pressure data in the hollow steel barrel 10 of the grouting test monitored by the strain gauge 12, the temperature data in the hollow steel barrel 10 of the grouting test monitored by the temperature sensor 13, the diffusion range data of the slurry in the hollow steel barrel 10 of the grouting test monitored by the wave velocity transmitter 14 and the wave velocity receiver 20 after solidification, and the water and ion liquid concentration data in the water storage tank 38 output by the control system (monitoring system) of the ion monitoring-adding integrated machine 30, and outputs the above data to the data classification unit after preliminary processing. (6): The data classification unit classifies and preliminarily processes the various data received by the data receiving unit, and then the data display unit can display the data processed by the data classification unit on the screen of the Internet device, and the construction party and the engineering party can view the specific data through the PC or smart phone application software around them.(7): During the experiment, the alarm prompt unit detected that the grouting pressure data monitored by the grouting pressure transmitter 5 was higher or lower than the normal output pressure data of the grouting pump (the grouting pressure was too low, which means that there might be no slurry in the slurry storage barrel 1, or the slurry delivery pipe 3 was blocked, etc.; the pressure was too high, which means that the high-pressure grouting pipe 6 was blocked, etc.), the strain gauge 12 detected that the pressure in the grouting test hollow steel barrel 10 was higher or lower than the normal pressure data (in the initial state of the present invention, the experimenter controlled the jack through the PLC to drive the top steel plate 18 to be located at the upper end of the grouting test hollow steel barrel 10; the grouting pressure was too low, which means that there might be insufficient slurry in the grouting test hollow steel barrel 10; the pressure was too high, which means that after the grouting test hollow steel barrel 10 was filled with slurry, the PLC control was abnormal, the grouting pump or the water injection pump had not stopped working, etc.), the temperature sensor 13 detected that the temperature in the grouting test hollow steel barrel 10 was higher or lower than the normal temperature data (the correct temperature data is as close as possible to the temperature of the actual construction area), and the grouting test hollow steel barrel 10 was higher or lower than the normal temperature data. When the diffusion range data of the slurry in the hollow steel barrel 10 after solidification is smaller than the normal data (a range that is too small indicates that the amount of slurry injected is too small or the proportion of water is too large), and the concentration ratio data of water and ionic liquid in the water storage barrel 38 is higher or lower than the normal concentration (the concentration ratio data that is higher or lower than the normal concentration indicates that there may be faults in the electric proportional valve or the control system), a text and sound warning signal is issued through the display screen interface, and the experimenter can make corresponding adjustments according to the actual situation, thereby improving the accuracy of the experimental data; specifically, through the data storage subunit of the alarm prompt unit, the construction party and the engineering party can both check and view the normal grouting pressure data monitored by the grouting pressure transmitter 5, the normal pressure data in the hollow steel barrel 10 of the grouting test monitored by the strain gauge 12, the normal temperature data in the hollow steel barrel 10 of the grouting test monitored by the temperature sensor 13, as well as the normal data of the expansion range of the slurry in the hollow steel barrel 10 of the grouting test after solidification, and the normal water and ionic liquid concentration data in the water storage barrel 38. (8): After the experiment is completed and the slurry solidifies, the experimenter removes the steel beam 8, and then knocks the bottom steel plate 9 with a hammer, etc., so that the bottom steel plate 9 and the lower end of the hollow steel barrel 10 for the grouting test are separated. Then the experimenter places the two outer ends of the hollow steel barrel 10 for the grouting test on the inner ends of the two steel beams 8 respectively, and then controls the piston rod of the jack 19 to move downward through the top steel plate 18 to push the solidified concrete experimental material downward, and then uses other testing equipment to test the physical and chemical properties of the material (the height of the steel beam 8 is higher than the height of the solidified concrete material in the post-solidification experiment).(9): During actual construction, when the engineering personnel are on-site, through the data storage subunit of the alarm unit, when the pressure data monitored by the strain gauge 12 installed at the construction station is too high or too low, when the temperature data monitored by the installed temperature sensor 13 is too high or too low, when the diffusion range data of the slurry after solidification monitored by the installed wave velocity transmitter 14 and wave velocity receiver 20 is too small, when the monitored ingredients in the concrete slurry are unqualified (different ingredients can reduce the corrosion effect of different types of corrosive ions on the solidified concrete at the corresponding grouting station), when the water and ion liquid concentration data in the water storage tank 38 are too high or too low, when the slurry pressure output by the grouting pump 4 and the water injection pump 28 (both are equipped with a grouting pressure transmitter 5 and a dynamic water pressure transmitter 27 respectively) is too high or too low, the construction party can be prompted to correct the corresponding data as much as possible to achieve a good grouting reinforcement effect in the relevant area.
