Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a device for detecting the water permeability coefficient of permeable concrete. Background Art

[0002] Permeable concrete, also known as porous concrete, sandless concrete, or permeable flooring, is a porous, lightweight concrete made from aggregate, cement, a reinforcing agent, and water. It contains no fine aggregate. Coarse aggregate is coated with a thin layer of cement paste, which bonds the coarse aggregate to form a honeycomb structure with evenly distributed pores. This makes it breathable, water-permeable, and lightweight. Testing the permeability of permeable concrete can be used to verify its quality.

[0003] A permeable concrete permeability coefficient test device, described in an existing Chinese patent application (authorization publication number: CN216411007U), comprises a water box, a placement box, and a water storage box. The water storage box is located directly above the water box and extends through the top surface of the water box. The water storage box comprises a water tank and a chute plate, both of which extend through the upper and lower end surfaces of the water tank. The chute plates are vertically fixed to both sides of the bottom end surface of the water tank, and the bottom ends of the chute plates are fixed to the top surface of the water box. The placement box is horizontally slidably mounted in the chute plate, extending through the upper and lower ends of the placement box. A water filling cylinder, equipped with a valve, extends through the bottom of the water tank. This utility model can visually display water permeability, improving detection and observation convenience.

[0004] During the testing process, the existing permeable concrete permeability coefficient testing device needs to first make a concrete sample, then place the concrete sample in a placement box inside the device, spray water at a high altitude, and then calculate its permeability based on the amount of water passing through the leaking part of the sample. However, in this testing method, in order to prevent water from flowing through the gap between the device and the sample and causing inaccurate measurement, the sample needs to be made slightly larger than the placement box, and then it needs to be laboriously inserted into the placement box. After the test, the sample needs to be crushed before it can be removed from the placement box, which makes the entire experimental process cumbersome and inconvenient. Utility Model Content

[0005] The purpose of this application is to solve the problem that the existing permeable concrete permeability coefficient detection device has difficulty in removing and placing concrete samples during the detection process. This application provides a permeable concrete permeability coefficient detection device.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

Then, the water spray plate is placed on the upper end of the sample through the placement structure, and the top of the sample is sealed. When the sample is undergoing water permeability testing, water flow can pass through the concrete, reducing water overflow, making the device more accurate during testing.

[0015] Furthermore, a guide column is fixedly connected to the machine body, and the guide column is slidably connected to the lifting rod.

[0016] By adopting the above technical solution, the movement of the lifting rod is limited by the guide column, making its movement more stable.

[0017] Furthermore, a fixing column is fixedly connected to the side plate, a fixing plate is rotatably connected to the fixing column, a torsion spring is sleeved on the fixing column, two ends of the torsion spring are respectively fixedly connected to the side plate and the fixing plate, an arc plate is fixedly connected to the fixing plate, and the arc plate is adapted to the sealing ring.

[0022] By adopting the above technical solution, the space between the sample and the leak plate is filled with a sealing gasket, which reduces the overflow of water between the bottom of the sample and the device, and strengthens the sealing effect between the sealing gaskets through the limiting pins and the limiting grooves.

[0023] In summary, this application has at least one of the following beneficial effects:

[0024] 1. In this application, when the device is used to test a concrete sample, the concrete sample is first placed on the leak plate, and then the rotating plate is rotated to rotate the bidirectional threaded rod. While the bidirectional threaded rod rotates, it drives the side plates to move toward each other along the limit columns to wrap both sides of the sample. Then, the drive motor is started to drive the lifting threaded rod to rotate, so that the lifting rod moves downward along the guide column, and the water spray plate is placed on the top of the sample, so that the sample can be quickly installed and disassembled during testing, reducing the problem of the sample being crushed and disassembled during the testing process, making the device more convenient in the process of testing the sample.

[0038] When the device is used to test a concrete sample, the concrete sample is first placed on the leak plate 19, and then the rotating plate 15 is rotated to rotate the bidirectional threaded rod 11. While the bidirectional threaded rod 11 rotates, it drives the side plates 12 to move toward each other along the limit columns 21 to wrap both sides of the sample. Then, the drive motor 6 is started to drive the lifting threaded rod 14 to rotate, so that the lifting rod 7 moves downward along the guide column 13, and the water spray plate 10 is placed on the top of the sample, so that the sample can be quickly installed and disassembled during testing, reducing the problem of the sample being crushed and disassembled during the testing process, making the device more convenient in the process of testing the sample.

[0041] Working principle: When the device is used to test the water permeability of concrete, the concrete sample is first placed on the leak plate 19, and then the rotating plate 15 is rotated to rotate the bidirectional threaded rod 11.
