Description

Technical Field

[0001] This utility model relates to the field of hydraulic concrete testing technology, and in particular to a portable rapid testing device for the impermeability of hydraulic concrete. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] Currently available concrete water permeability testing devices mostly use water pouring to test the permeability of concrete, which is a relatively simple testing method and affects the actual water permeability test results of concrete. Based on this, this application proposes a portable rapid testing device for the water permeability of hydraulic concrete, which can solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a portable rapid testing device for the impermeability of hydraulic concrete.

[0005] The purpose of this utility model is achieved through the following technical solution: a portable rapid testing device for the impermeability of hydraulic concrete, comprising a testing box and a test block. A humidity sensor is installed on the bottom wall of the testing box, and the test block is located above the humidity sensor. The probe on the humidity sensor extends into the test block. A sealing sleeve is installed at the top inside the testing box, and its bottom is tightly fitted with the test block. The inside of the sealing sleeve is filled with a permeation liquid, and a pressure plate that can move up and down is installed inside the sealing sleeve.

[0006] Optionally, a cover for sealing is installed on the top of the testing box, and a telescopic cylinder is installed in the middle of the top surface of the cover, with the pressure plate installed at the output end of the telescopic cylinder.

[0007] Optionally, a sealing ring is installed on the outer side of the pressure plate, and its outer surface is in contact with the inner wall of the sealing sleeve.

[0008] Optionally, supports are installed on both sides of the bottom wall of the test chamber, and the test block is located above the two supports.

[0009] Optionally, drain valves are installed on both sides below the testing box.

[0010] This utility model has the following advantages:

[0011] This portable rapid testing device for the impermeability of hydraulic concrete uses a testing box as its main body. A humidity sensor is installed at the bottom of the testing box, and its probe extends into the test block. Liquid is added to the top of the testing box, and the impermeability of the test block can be measured by detecting the sensing time of the humidity sensor. At the same time, a sealing sleeve is installed on the top of the testing box, and its lower part is in close contact with the test block. Inside the sealing sleeve is a pressure plate that can move up and down. After liquid is poured into the sealing sleeve, the up and down movement of the pressure plate can provide pressure for the permeation liquid, so that the staff can test the impermeability of the test block in different environments. The permeated liquid can be discharged from the drain valve at the bottom of the testing box for the convenience of the staff. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0017] like Figures 1 to 3 As shown, a portable rapid testing device for the impermeability of hydraulic concrete includes a testing box 1 and a test block 7. A humidity sensor 8 is installed on the bottom wall of the testing box 1. The test block 7 is located above the humidity sensor 8, and the probe on the humidity sensor 8 extends into the test block 7. A sealing sleeve 4 is installed at the top inside the testing box 1, and its bottom is tightly fitted with the test block 7. The inside of the sealing sleeve 4 is filled with a permeation liquid, and a pressure plate 5 that can move up and down is installed inside the sealing sleeve 4.

[0018] As an optional technical solution of this utility model, a box cover 2 for sealing is installed on the top of the test box 1. A telescopic cylinder 3 is installed in the middle of the top surface of the box cover 2. The pressure plate 5 is installed at the output end of the telescopic cylinder 3. In this way, the pressure plate 5 can be driven to move up and down reciprocally by the telescopic cylinder 3. The telescopic cylinder 3 can be replaced with a telescopic motor or other components according to the actual situation, as long as it can drive the pressure plate 5 to move up and down.

[0019] As an optional technical solution of this utility model, a sealing ring 6 is installed on the outer side of the pressure plate 5, and its outer surface is in contact with the inner wall of the sealing sleeve 4, which can improve the sealing performance between the pressure plate 5 and the sealing sleeve 4.

[0020] As an optional technical solution of this utility model, brackets 11 are installed on both sides of the bottom wall of the test box 1, and the test block 7 is located above the two brackets 11. In this way, the brackets 11 can support the test block 7 to avoid direct contact between the test block 7 and the humidity sensor 8.

[0021] As an optional technical solution of this utility model, drain valves 10 are installed on both sides below the test box 1, which facilitates the discharge of the permeate accumulated in the test box 1 and makes it convenient to use.

[0022] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: The detection box 1 serves as the main body of the device. A humidity sensor 8 is installed at the bottom of the detection box 1, with its probe 9 extending into the test block 7. Liquid is added to the top of the detection box 1. By measuring the sensing time of the humidity sensor 8, the permeability resistance of the test block 7 can be determined. Simultaneously, a sealing sleeve 4 is installed above the detection box 1, with its lower part in close contact with the test block 7. Inside the sealing sleeve 4, a pressure plate 5 that can move up and down is installed. After liquid is poured into the sealing sleeve 4, the up-and-down movement of the pressure plate 5 provides pressure to the permeate, facilitating the testing of the permeability resistance of the test block 7 under different environments. The permeated liquid can be discharged from the drain valve 10 at the bottom of the detection box 1 for convenient use by the staff.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
