Description

Technical Field

[0001] This utility model relates to the field of self-healing concrete, specifically to an experimental device for self-healing microbial concrete based on organic plate clamping. Background Technology

[0002] Self-healing concrete is a new type of composite material that mimics the regeneration and recovery mechanism of animal bone tissue after injury. It uses a combination of repair adhesive and concrete materials to achieve self-repair and regeneration of damaged materials, restoring or even improving material properties.

[0003] This new material is currently in the experimental stage, meaning it has not been put into large-scale use. Its functions and effects have not yet been perfected to a mature stage, so a large number of tests are needed to verify its reliability.

[0004] The purpose of this experimental device for this new material is to squeeze a sample (i.e., a standardized concrete block) to create a crack as required by the experiment, then place it in water for a period of time to observe its self-healing effect. The experiment is repeated, and then targeted improvements are made. This is the function of the experimental device.

[0005] Most existing experimental equipment uses a ring-shaped box filled with flowing water and sand to simulate the working environment of concrete in water. The samples are then observed periodically. However, there are some shortcomings. When simulating the underwater environment, the sample needs to be lifted up for each observation. After being lifted up, the original position of the sample is covered by sand. After putting it back in, the sand and gravel need to be readjusted to restore it to its original state, which is too cumbersome.

[0006] Therefore, an experimental device is needed that is convenient for maintaining the experimental environment of the sample and for easy observation. Utility Model Content

[0007] To address the aforementioned problems, this invention provides a microbial concrete self-healing experimental device based on organic plate clamping.

[0008] This utility model is achieved through the following technical solution:

[0009] An experimental device for microbial self-healing concrete based on organic plate clamping includes a box body with a flow area inside. A first partition is fixedly installed in the flow area, and a first circulation pump is fixedly embedded in the first partition. The output and input ends of the first circulation pump are located on opposite sides of the first partition, respectively. A U-shaped baffle is fixedly installed inside the box body. A positioning rod is fixedly installed on the top of the box body, and an L-shaped pull plate is sleeved on the positioning rod. An L-shaped bearing plate is fixedly connected to the bottom end of the L-shaped pull plate, and a sample is placed on the L-shaped bearing plate. An adjusting screw is screwed onto the L-shaped pull plate, and a pressure plate is rotatably connected to the bottom end of the adjusting screw. The bottom end of the pressure plate is fitted against the top end of the sample. An electric telescopic rod is fixedly installed on one side of the box body, and a connecting frame is fixedly installed at the top end of the electric telescopic rod. The connecting frame is U-shaped, and an observation plate is fixedly connected between the two ends of the connecting frame. The observation plate is also U-shaped.

[0010] Preferably, a U-shaped push rod is inserted into the connecting frame, and scrapers are fixedly installed at both ends of the U-shaped push rod.

[0012] Preferably, a pad is fixedly installed on the L-shaped pull plate, and a locking bolt is screwed onto the pad.

[0013] Preferably, a temperature controller is fixedly installed inside the chamber.

[0014] Preferably, two second partitions are fixedly installed inside the box, and a second circulation pump is installed between the two second partitions.

[0016] Preferably, the observation plate, U-shaped baffle, pressure plate, and L-shaped support plate are all made of transparent organic materials, such as transparent acrylic sheets.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: the device is equipped with an observation plate, so when observing samples, the observation plate is inserted first, and then the sample is lifted, so that the sand will maintain its original state, thus eliminating the need to repeatedly repair the sand.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0022] like Figure 1 , Figure 2As shown, an experimental device for self-healing microbial concrete based on organic plate clamping includes a box body 1. A flow area is provided inside the box body 1, and a first partition 2 is fixedly installed within the flow area. A first circulation pump 3 is fixedly embedded in the first partition 2. The output and input ends of the first circulation pump 3 are located on opposite sides of the first partition 2, respectively. A U-shaped baffle 16 is fixedly installed inside the box body 1. A positioning rod 17 is fixedly installed on the top of the box body 1, and an L-shaped pull plate 21 is sleeved on the positioning rod 17. An L-shaped bearing plate 20 is fixedly connected to the bottom end of the L-shaped pull plate 21, and a sample is placed on the L-shaped bearing plate 20. An adjusting screw 18 is screwed onto the L-shaped pull plate 21, and a pressure plate 19 is rotatably connected to the bottom end of the adjusting screw 18. The bottom end of the pressure plate 19 is fitted against the top end of the sample. An electric telescopic rod 15 is fixedly installed on one side of the box body 1, and a connecting frame 1 is fixedly installed at the top end of the electric telescopic rod 15. 2. The connecting frame 12 is U-shaped, and an observation plate 11 is fixedly connected between the two ends of the connecting frame 12. The observation plate 11 is U-shaped. During installation, the L-shaped pull plate 21 is lifted, and the sample is placed on the L-shaped support plate 20. The adjusting screw 18 is rotated to lower the pressure plate 19, thus clamping the sample. After clamping, the L-shaped pull plate 21 is lowered, and then sand and other materials are filled into the flow area to simulate the working environment, so that the experiment can be carried out. When observation is required, the electric telescopic rod 15 is activated to lower the observation plate 11. During the descent, the sand and gravel on both sides of the sample are blocked until the bottom is reached, and then the descent stops. At this time, the observation plate 11 and the U-shaped baffle form a U-shaped space. Then the sample can be pulled up for observation, but the sample should not be pulled out of this U-shaped space to facilitate subsequent operations.

[0023] A U-shaped push rod 13 is inserted into the connecting frame 12. Scrapers 14 are fixedly installed at both ends of the U-shaped push rod 13, which can effectively remove water stains or dirt on the observation plate 11 and ensure the observation environment.

[0024] A sliding guide rod is inserted into the connecting frame 12. A bracket is fixedly installed at the bottom of the guide rod. The bracket is fixedly connected to the side wall of the housing 1. The bottom of the electric telescopic rod 15 is fixedly installed on the bracket. The guide rod plays a guiding role to ensure the stability of the observation plate 11 when it is raised and lowered.

[0025] A pad is fixedly installed on the L-shaped pull plate 21, and a locking bolt is screwed onto the pad. After the sample is placed in, the bolt on the pad is rotated to keep the L-shaped pull plate 21 and the positioning rod 17 in a fixed position to ensure the stability of the experiment.

[0026] A temperature controller 4 is fixedly installed inside the housing 1, which can easily adjust the water temperature.

[0027] Two second partitions 5 are fixedly installed inside the chamber 1. A second circulation pump 6 is installed between the two second partitions 5. A water injection pipe 7 is fixedly connected to the output end of the second circulation pump 6. One end of the water injection pipe 7 is fixedly connected to and communicates with the side wall of the observation plate 11. Before lifting the sample for observation, the second circulation pump 6 is started to inject water so that the sample remains in the water after being lifted. This ensures the accuracy of the experiment and avoids other unexpected changes caused by the sample being exposed to air.

[0028] A third circulation pump 8 is installed between one of the second partitions 5 and the inner wall of one side of the housing 1. The output end of the third circulation pump 8 is fixedly connected to a drain pipe 10, one end of which extends into the space between the two second partitions 5. The input end of the third circulation pump 8 is fixedly connected to a water inlet pipe 9, one end of which extends into the flow area and communicates with it. Since water is injected into the housing during observation, the third circulation pump 8 is installed to prevent water from overflowing. It draws out excess water and refills it between the two second partitions 5, forming a stable circulation.

[0029] The observation plate 11, U-shaped baffle 16, pressure plate 19 and L-shaped support plate 20 are all made of transparent organic materials, such as transparent acrylic sheets, so that they can be easily observed.
