The specific implementation process is as follows:

Close the switch valve of the slurry discharge device to prevent the concrete material from flowing out of the slurry discharge hole when mixing concrete in the container; take out all the strong magnet devices, and the vertical grooves that are in contact with the outer strong magnet block and the inner strong magnet block, Apply lubricating oil to the side wall of the box, then install the powerful magnet outer device on the top of the vertical groove on the side wall of the box, install the inner device of the strong magnet on the inner side of the side wall of the box, and place it horizontally inside the box; hold The outer handle is pressed down, and the inner device of the strong magnet slides down the side wall to the bottom of the storage box through the strong attraction between the strong magnet block and the outer strong magnet block; a certain proportion of fine sand, cement and water are stirred to ensure uniform and stable Finally, the concrete material is formed, and the stirred concrete material is put into the container; the clamps on both sides are inserted into the corresponding vertical groove top groove on the side wall of the container, and the position of the corresponding top groove cannot exceed the top of the concrete material inside the container. The horizontal position of the liquid surface makes the strong magnet device stir the net in the concrete material when it slides up and down, so that the outside air will not be brought in when the sliding surface exceeds the liquid level at the top of the concrete material and enters the concrete material; put the container on the vibration The corresponding position of the board, through the horizontal sliding clamping device, clamp the clamping block and the bottom slot on the container, so that the container cannot move freely;

Then turn on the switch of the vibration device to make the vibration motor start to work; the strong vibration of the vibration motor acts on the vibration of the vibration plate, which is transmitted to the container; after the concrete material in the container is subjected to the transmitted vibration, the air bubbles in the material get rid of the surrounding concrete The blocking effect of the vibration device moves upward until it enters the air; after the vibration device works for 3-5 minutes, turn off the switch of the vibration device, hold the outer handle to drive the agitation net to move up and down but not exceed the liquid level of the top of the concrete, so that the external air will not be brought Into the concrete material, and at the same time help the remaining air bubbles in the concrete material to get rid of the blockage of the surrounding concrete. After moving up and down for 10-15 back and forth, press the outer handle down to make the mixing net reach the bottom of the container. ;Turn on the switch of the vibration device and continue to vibrate for 3-5 minutes, then close it, use a powerful magnet device to manually remove air bubbles, and repeat this operation in turn until the air bubble removal effect in the concrete material meets the test requirements;

Turn off the vibrating device, and set up supporting blocks between both sides of the vibrating plate and the supporting box, which will play a role in bearing pressure during the subsequent pressing down process; remove the blocking block, and pull the outer handle of the powerful magnet device upward until Stir the net away from the concrete material, remove all the powerful magnet devices; erect the reaction frame and the pressing device directly above the vibrating device and the container, so that the pressured top cover is aligned with the inner cavity of the container; open the control to apply pressure The switch of the motor, the telescopic rod extends downward to drive the pressure top cover to move downward, and the force transmission plate plays the role of transmitting pressure; when the pressure top cover is close to the liquid surface of the concrete material and a small amount of concrete material enters the vent hole, Turn off the control switch of the pressure applying motor, and close the air hole at the same time, so that the pressure top cover becomes a tightly closed block; use a rubber tube with a suitable size to install it on the slurry discharge hole, open the switch valve, and then turn on the pressure applying motor to turn on the The concrete material is discharged through the grout hole until the concrete material penetrates the entire rubber tube and flows out in a small amount. The rubber tube is inserted into the bottom of the mold used for the test, and the concrete material is continuously poured into the mold under the pressure of the pressure motor. The concrete material will not be mixed with the outside air due to its high density; when all the molds are filled, turn off the pressure motor control switch, clean the whole set of devices, and complete all operations.

In the above-mentioned embodiment, the upper and lower sides of the inner strong magnet block are sharp points, which can reduce the resistance suffered by it moving up and down in the concrete material;

The role of lubricating oil is to lubricate the surface of the outer strong magnet block and the inner strong magnet block, so that the resistance suffered during the sliding process of the side wall of the storage box is reduced;

The strong magnet inner device and the strong magnet outer device are closely attached to the side wall of the container through the strong attraction between the magnets. When the outer handle is pulled up and down artificially, the strong magnet inner device also moves up and down;

The top groove of the vertical groove on the side wall of the container plays the role of fixing the block;

The vibration spring plays a role of damping, and when connecting the lower support box, it can avoid the strong vibration of the lower support box;

The agitation net helps the remaining air bubbles in the concrete material to get rid of the blockage of the surrounding concrete;

The top support block plays a pressure bearing role in the subsequent pressing down process of the pressure roof;

Existence of ventilation hole is to prevent the air in the box from being pressed into the concrete material when the pressure top cover enters the concrete material after entering the container.
