DETAILED DESCRIPTION

[0029] The utility model will be explained in detail below in combination with each embodiment shown in the drawings, but it should be explained that these embodiments are not the limitation of the utility model, and the equivalent transformation or substitution of function, method or structure made by the ordinary skill in the art according to these embodiments all belong to the protection scope of the utility model.

[0030] Referring to the drawings, Figures 1-8 The grouting material anti-scouring performance simulation test device in the embodiment includes a power scouring mechanism communicated with the constant temperature box 1, the outflow box 4 in the power scouring mechanism is at least divided into three scouring simulation boxes 40 with different smoothness through a shunt mechanism, and the flow outlet of each scouring simulation box 40 is communicated with the waste liquid storage box 13 through a waste liquid pipe 17; in the test, in order to ensure better impact and flow, the embodiment increases a speed regulating mechanism during shunting, thereby meeting the adjustment of different speeds and realizing the effect that the water flow speed entering the different scouring simulation boxes 40 is different, so that more environmental possibilities are simulated.

[0031] When the slurry flows, the slurry flowing out of the slurry storage tank 11 in this embodiment flows out of the slurry outlet 5 under the action of the slurry control mechanism, flows into the corresponding flushing simulation box 40 through the slurry conveying pipe 12, and then flows into the set flushing cavity under the guidance of the guiding mechanism, and is impacted by the water flow with speed, and then flows out into the waste liquid storage tank 13 through the waste liquid pipe after being impacted by the water flow with speed.

[0032] In the above process, due to the existence of multiple flushing simulation boxes, different rough surfaces or performance flushing cavities are formed in each flushing simulation box, and then impact is performed in combination with different water flow speeds and slurry speeds, and finally flows out, thereby completing performance simulation through quality difference, and achieving multiple purposes at once.

[0033] In this embodiment, the setting of multiple performance flushing cavities simultaneously satisfies different performance detection and simulation tests, achieves multiple purposes at once, and improves the overall detection efficiency.

[0034] Firstly, the shunt mechanism is introduced as follows:

[0035] In this embodiment, the shunt mechanism includes a water conveying main pipe 9 connected with the outflow box 4, and a plurality of water conveying branch pipes 6 connected with the flushing simulation box 40 in one-to-one correspondence and arranged in parallel at the output end of the water conveying main pipe 9. The pressure valve 7 and the first flow meter 8 forming the speed regulation mechanism are arranged on each water conveying branch pipe 6. Specifically, the constant temperature water in the constant temperature box 1 is conveyed into the outflow box 4 through the water conveying pipe 3, and then the water in the outflow box 4 flows into the plurality of water conveying branch pipes 6 through the water conveying main pipe 9, and each water conveying branch pipe 6 is connected with one flushing simulation box 40. During the water flow, the pressure valve 7 is arranged on each water conveying branch pipe 6 to adjust the speed, and then the speed is measured through the first flow meter 8.

[0036] Secondly, the grouting control is introduced.

[0037] In this embodiment, the slurry flows into the flushing simulation box 40 through the slurry conveying pipe 12 and the slurry distribution pipe 10 after the outlet of the slurry mechanism.

[0038] In order to avoid the slurry flowing to other places, the guiding mechanism includes the top plate 20 located inside the slurry inlet 19 and provided with the pipe hole 28, and the air pressure output plate 27 located on both sides of the top plate 20, and the air pressure output plate 27 forms a guiding path converging towards the top plate. At this time, the air pressure output plate 27 is two, which are arranged on both sides of the top plate, and then it is connected with the pressure mechanism, so that the airflow in the box converges towards the top plate under the action of pressure and cannot flow out.

[0039] Thirdly, the three kinds of flushing simulation boxes are introduced.

[0040] In this embodiment, more types of scour simulation chambers can actually be set. For example, if four different construction surfaces are required, four types of scour simulation chambers can be set. In this embodiment, refer to... Figures 1-2 As can be seen, three scouring simulation chambers with different smoothness are set up, including at least a first scouring simulation chamber 41 with smooth inner wall, a second scouring simulation chamber 42 with rough inner wall, and a third scouring simulation chamber 43 filled with a medium structure. The specific roughness and medium structure can be selected according to the requirements.

[0041] The first flushing simulation box 41 in this embodiment includes an inlet 22 and an outlet 31 located in the lower part of the first flushing simulation box 41. The flushing cavity is formed by connecting the inlet 22 and the outlet 31 through at least a smooth surface 24, so that the slurry and water impact are carried out in the flushing cavity.

[0042] See attached document Figure 4 As shown, the flushing chamber includes a bottom plate with a smooth surface 24 and a first lateral baffle 23 and a second lateral baffle 25 located on both sides of the bottom plate. The distance between the first lateral baffle 23 and the second lateral baffle 25 is greater than the diameter of the water inlet 22, thereby facilitating the outflow and impact of water and slurry.

[0043] The second flushing simulation chamber 42 includes a rough bottom plate 30 forming the bottom of the second flushing simulation chamber and having a rough surface on its surface. The two ends of the rough bottom plate 30 are connected to the water inlet 22 and the liquid outlet 31. The addition of the rough bottom plate, with its rough surface, provides a certain degree of roughness.

[0044] The third scour simulation chamber 43 includes an inlet 22 and an outlet 31 located in the lower middle part. At least the lower middle part of the third scour simulation chamber, below the inlet 22 and outlet 31, is filled with a media structure 26. The media structure 26 can be placed as needed, and then the scour resistance of the grouting material under this media structure condition can be simulated for performance monitoring.

[0045] like Figures 1-2 As shown, this is a simulation experimental device for the erosion resistance of grouting materials under different conditions in this embodiment. It consists of three parts: a dynamic water flushing system, a grout control system, and a flushing simulation chamber.

[0046] The dynamic water flushing system is mainly composed of a thermostat 1, a water delivery pipe 3, an outflow tank 4, a water delivery branch pipe 6, a pressurizing valve 7, a water delivery main pipe 9, a waste liquid storage tank 13, a waste liquid pipe 17 and the like, which are all assembled on a base 2. The dynamic water flushing system has three water delivery routes, i.e. water flows out of the thermostat 1 and the outflow tank 4, passes through the water delivery main pipe 9 and the water delivery branch pipe 6, and is pressurized by the pressurizing valve 7 to change the flow rate of the water, and then reaches the water inlet 22 of each flushing simulation tank 40. The waste liquid flushed out by the water flows out of the liquid outlet 31, and then flows into the waste liquid storage tank 13 through the waste liquid pipe 17.

[0047] Water flows out of the thermostat 1 and the outflow tank 4, passes through the water delivery main pipe 9 and the water delivery branch pipe 6, and is pressurized by the pressurizing valve 7 to change the flow rate of the water, and then reaches the water inlet 22 of the second flushing simulation tank 42. The waste liquid flushed out by the water flows out of the liquid outlet 31, and then flows into the waste liquid storage tank 13 through the waste liquid pipe 17. Water flows out of the thermostat 1 and the outflow tank 4, passes through the water delivery main pipe 9 and the water delivery branch pipe 6, and is pressurized by the pressurizing valve 7 to change the flow rate of the water, and then reaches the water inlet 22 of the third flushing simulation tank 42. The waste liquid flushed out by the water flows out of the liquid outlet 31, and then flows into the waste liquid storage tank 13 through the waste liquid pipe 17.

[0048] The slurry control system is provided with a second flow meter 14 and a slurry pressurizing valve. The working principle is that the slurry is transported to different flushing simulation tanks 40 through the slurry storage tank 11, the slurry delivery pipe 12 and the like, and then through the slurry inlet 19.

[0049] The first flushing simulation tank 41 is mainly a smooth plane flushing simulation tank. The working principle is that the slurry slowly flows into the tank from the pipe hole 28 of the slurry inlet, and then the pipe hole 28 is provided to prevent the slurry from being directly distributed unevenly into the tank from the pipe. Then, the air pressure output plates 27 on the left and right sides of the pipe hole can make the slurry fully flow onto the bottom plate with a smooth surface 24. Then, the slurry is simulated under different water flow rates, and finally part of the slurry flows out of the liquid outlet under the action of the water flushing. According to the formula slurry retention rate = retained slurry / total slurry mass, the total slurry mass is the weight before the water flushing, and the retained slurry is the weight after the water flushing.

[0050] The second scouring simulation chamber 42, forming a rough surface scouring simulation chamber, works by the slurry slowly flowing into the chamber from the inlet pipe 28. To prevent the slurry from distributing around the pipe and failing to flow fully into the chamber, air pressure output plates on both sides of the pipe ensure the slurry flows fully onto the rough base plate 30. Next, flowing water at different velocities enters the simulation chamber through the inlet, simulating the scouring resistance of the grouting material on different roughness surfaces under varying water flow rates. Finally, some slurry flows out from the outlet under the scouring action of the flowing water. The slurry retention rate is calculated as: Slurry retention rate = Retained slurry / Total slurry mass, where the total slurry mass is the weight before scouring with flowing water, and the retained slurry is the weight after scouring with flowing water. The scouring resistance of the slurry on surfaces with different water flow rates and roughness is calculated.

[0051] For the third scouring simulation chamber 43, which is filled with different media, the working principle is mainly that the slurry flows into the chamber slowly through the pipe hole to prevent uneven distribution of the slurry from entering directly from the pipe. To prevent the slurry from being distributed around the pipe hole and not fully flowing into the chamber, air pressure output plates on both sides of the pipe hole ensure that the slurry flows fully into the medium voids inside the simulation chamber. Next, flowing water at different velocities flows into the simulation chamber through the water inlet to simulate the scouring performance of the grouting material in different media under different water flow velocities. Finally, some slurry flows out from the outlet 39 under the action of flowing water. According to the formula, slurry retention rate = retained slurry / total slurry mass, where the total slurry mass is the weight before flowing water scouring and the retained slurry is the weight after flowing water scouring. The scouring performance of the slurry under different water flow velocities and different filling media is calculated.

[0052] In this embodiment, the waste liquid storage tank 13 is connected to the slurry storage tank 11 through the connecting pipe 15, providing a basis for subsequent reuse.

[0053] In this embodiment, the medium structure includes sand particles or gravel, etc.
