Description

Technical Field

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

[0002] Before pouring concrete, test blocks need to be made to test the strength and permeability of the concrete. Common concrete test blocks are mainly in the shape of cubes and cylinders. Cubic concrete test blocks are used for compression tests, while cylindrical concrete test blocks are used for permeability tests.

[0003] The existing concrete water permeability testing equipment is relatively cumbersome to use. It is necessary to first connect the cylindrical concrete test block to the mold through hydraulic equipment to prevent water from penetrating from the gap between the concrete test block and the testing equipment. Otherwise, due to insufficient sealing, water will seep out of the concrete test block, affecting the detection accuracy of the water permeability. Then, the mold containing the cylindrical concrete test block is placed in the testing equipment to start the testing work. After the test is completed, it is necessary to first take the mold containing the cylindrical concrete test block out of the testing equipment, and then separate the mold from the cylindrical concrete test block through hydraulic equipment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a concrete water permeability detection device to solve the technical problem that the detection operation is relatively complicated.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete water permeability detection device, comprising a table body and a water tank, a clamping assembly is arranged on the top of the table body, and the clamping assembly comprises a first shield, a first sealing gasket is connected inside the first shield, and a first sealing strip is connected to the outer surface of the first sealing gasket, a second shield is connected to one side of the outer surface of the first shield, and a second sealing gasket is connected inside the second shield, a second sealing strip is connected to the back of the second sealing gasket, a groove is arranged at the bottom of the second sealing gasket, an observation port is arranged at the top of the first shield, and a conveying pipe runs through the bottom of the first shield.

[0006] By adopting the above technical solution, the second protective cover is first rotated to open, and then the concrete test block is placed inside the first protective cover and the second protective cover is closed. At this time, the gap between the concrete test block and the two protective covers is filled by the first sealing pad and the second sealing pad, and the gap between the two sealing pads is filled by the first sealing strip and the second sealing strip, thereby preventing water from overflowing through the gap between the concrete test block and the two protective covers to affect the water permeability detection. At the same time, water is transported to the bottom of the concrete test block through the delivery pipe. When the water permeability of the concrete test block is high, water passes through the concrete test block and overflows from the top of the concrete test block. The water can be observed through the observation port. When the water permeability of the concrete test block is low, water cannot pass through the concrete test block, so no water can be seen during observation.

[0007] Furthermore, the first shield is fixedly connected to the table body via bolts, and the second shield is rotatably connected to the first shield via a hinge.

[0008] By adopting the above technical solution, the staff rotates the second protective cover to open it, then puts the concrete test block into the first protective cover, and then closes the second protective cover.

[0009] Furthermore, the first sealing strip is matched with the second sealing strip, and the cross-sections of the first sealing strip and the second sealing strip are both serrated.

[0010] By adopting the above technical solution, the gap between the concrete test block and the two shields is filled by the first sealing pad and the second sealing pad, and the gap between the two sealing pads is filled by the first sealing strip and the second sealing strip.

[0011] Furthermore, the first sealing gasket, the second sealing gasket, the first sealing strip and the second sealing strip are all made of rubber material.

[0012] By adopting the above technical solution, the first sealing pad, the second sealing pad, the first sealing strip and the second sealing strip can prevent water from overflowing through the gap between the concrete test block and the two shields to affect the water permeability detection.

[0013] Furthermore, a fastener is connected to one side of the first shield.

[0014] By adopting the above technical solution, the staff closes the second protective cover and fastens the fasteners to complete the limiting between the first protective cover and the second protective cover. The staff releases the fasteners, and then the staff turns and opens the second protective cover to take out the concrete test block.

[0015] Furthermore, the fastener is rotatably connected to the first shield, and the fastener is detachably connected to the second shield.

[0016] By adopting the above technical solution, the staff puts the concrete test block into the first protective cover, and then the staff closes the second protective cover and fastens the fasteners to complete the limiting between the first protective cover and the second protective cover.

[0017] Furthermore, the water tank is located below the table body, a hand valve is connected to the outer surface of the water tank, a water pump is installed on one side of the water tank, and a solenoid valve is connected to the water outlet of the water pump through a pipeline.

[0018] By adopting the above technical solution, the staff turns on the water pump and the solenoid valve. After the water pump is started, the water in the water tank is sent into the pipe. Then the water flows through the pipe, the solenoid valve and the delivery pipe in sequence, so that the water is delivered to the bottom of the concrete test block. When the water permeability of the concrete test block is high, the water passes through the concrete test block.

[0019] Furthermore, the solenoid valve is connected to the delivery pipe through a pipeline.

[0020] By adopting the above technical solution, after the water pump is started, the water in the water tank is sent into the pipeline, and then the water flows through the pipeline, the solenoid valve and the delivery pipe in sequence.

An observation port 505 is provided at the top of the first protective cover 501. When the water permeability of the concrete test block is high, water passes through the concrete test block and overflows from the top of the concrete test block. At this time, the staff can check the water through the observation port 505. A delivery pipe 506 runs through the bottom of the first protective cover 501. The water flows through the pipeline 7, the solenoid valve 8 and the delivery pipe 506 in sequence, so that the water is delivered to the bottom of the concrete test block.

At this time, the staff can check the water through the observation port 505. When the water permeability of the concrete test block is low, the water cannot pass through the concrete test block, so the staff cannot see the water at the observation port 505.

[0041] After the test is completed, the staff loosens the fastener 6, and then the staff turns to open the second protective cover 502 to take out the concrete test block.
