Description

Technical Field

[0001] The utility model belongs to the technical field of concrete testing equipment, and particularly relates to a concrete anti-permeability performance testing device. Background Art

[0002] During the use of concrete structures, they will be eroded by various external environments, one of the main factors of which is water seepage. If the concrete's impermeability is poor, the water in the concrete will not be able to diffuse to the outside when the water evaporates, and the concrete will seep inside. This phenomenon will cause the strength of the concrete to decrease, corrosion to increase, and the service life to shorten, thus endangering the safety of the building structure. Therefore, before the concrete is applied to the actual construction site, it is an important means to ensure the quality and safety of the building to conduct an impermeability test on it.

[0003] Existing concrete impermeability testing equipment usually uses the osmotic pressure method to test the concrete impermeability. However, due to the limited water pressure applied to the concrete, it cannot well reflect the concrete's impermeability, resulting in a certain deviation between the obtained experimental data and the authenticity.

[0047] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0048] The most critical concept of the utility model is: the second stop valve is closed, and the water in the water tank is guided to the boosting device by the pump body, so that the water pressure in the anti-seepage detection chamber is continuously increased with the cooperation of the boosting device and the second stop valve. When the pressure value reaches the specified value, the first stop valve, the boosting device and the pump body are closed in sequence through the controller, so that the water pressure in the pipeline is maintained at a high pressure state that meets the test requirements.

[0049] Please refer to Figures 1 to 3The concrete anti-permeability performance testing device provided by the utility model comprises a controller, a pressure device, and a water tank 1, a pump body 2, a pressure boosting device 3, a first stop valve, an anti-permeability detection chamber 4 and a second stop valve which are sequentially connected and form a circulation loop;

[0050] The detection end of the pressure device is arranged in the anti-seepage detection cavity 4;

[0051] The pressure device, the pump body 2, the pressure boosting device 3, the first stop valve and the second stop valve are all electrically connected to the controller.

[0052] Specifically, the booster device 3 can be any commercially available device that can increase the pressure of the medium inside the pipeline, such as a booster pump or an air booster, etc. The pump body 2 and the booster device 3 both include a pressure relief valve, and the pressure relief valve is connected to the water tank 1 to avoid pipe bursting due to excessive pipeline pressure.

[0053] From the above description, it can be seen that the beneficial effects of the utility model are: providing a concrete anti-seepage performance testing device, when working, the second stop valve is in a closed state, and the pump body 2 guides the water in the water tank 1 to the boosting device 3, so that the water pressure in the anti-seepage detection chamber 4 is continuously increased with the cooperation of the boosting device 3 and the second stop valve. When the pressure value reaches the specified value, the first stop valve, the boosting device 3 and the pump body 2 are closed in sequence by the controller, so that the water pressure in the pipeline is maintained at a high pressure state that meets the test requirements. Compared with the existing concrete anti-seepage performance testing device, high water pressure can be applied to the surface of the concrete sample to be tested during the entire test process, so that the anti-seepage performance of the concrete sample is always in a limit state, so that the anti-seepage ability of the concrete sample can be reflected to the greatest extent, and the test efficiency can be indirectly improved.

[0054] Furthermore, the number of the anti-seepage detection chambers 4 is at least two.

[0055] Furthermore, the above-mentioned concrete anti-permeability testing device further comprises at least two interconnected pipe groups 5;

[0056] The first stop valve is connected to the anti-seepage detection chamber 4 through the pipe group 5.

[0057] Specifically, each tube group 5 can also be an independent structure, and each tube group 5 is connected to the first stop valve and the anti-seepage detection chamber 4 at the same time to ensure that when a connection problem occurs between a certain tube group 5 and the anti-seepage detection chamber 4, other tube groups 5 can replace the tube group 5 to perform water pressurization work.

[0058] From the above description, it can be seen that the design has made specific improvements to the number of anti-seepage detection chambers 4, as well as the connection relationship between the pipe group 5 and the anti-seepage detection chamber 4, to ensure that a single test can detect as many concretes with different annotations as possible, thereby improving the detection efficiency; at the same time, setting up multiple pipelines connected to the anti-seepage detection chamber 4 can avoid blockage or damage to a certain pipeline, thereby affecting the normal operation of the detection device.

[0059] Furthermore, the anti-seepage detection chamber 4 includes a chamber body 41, a sealing member 42 and a pressing assembly 43;

[0060] A water inlet is provided at the bottom of the cavity 41;

[0061] The first stop valve is connected to the anti-seepage detection chamber 4 through the water inlet;

[0062] The sealing member 42 is disposed on the inner wall of the cavity 41;

[0063] The pressing assembly 43 is arranged at the opening of the cavity 41;

[0064] The pressing end of the pressing assembly 43 is disposed toward the bottom of the cavity 41 .

[0065] From the above description, it can be seen that the design has made specific improvements to the composition structure of the anti-seepage test cavity 4. When the concrete sample to be tested is placed inside the cavity 41 and the pressing end of the pressing assembly 43 presses the concrete to the bottom of the cavity 41, the concrete presses the seal 42 to effectively fill the gap between the concrete and the inner wall of the cavity 41, thereby indirectly maintaining pressure during the anti-seepage test and preventing moisture from leaking from the gap to affect the final test results.

[0066] Furthermore, the anti-seepage detection chamber 4 also includes two hanging ears 44;

[0067] The hanging ear 44 is relatively arranged outside the cavity 41;

[0068] The hanging ears 44 are all provided with limiting notches;

[0069] The opening directions of the limiting notches are consistent;

[0070] The pressing assembly 43 includes a support rod 431 and a pressing rod 432 threadedly connected to the support rod 431;

[0071] When the pressing assembly 43 presses concrete, the support rod 431 is engaged with the limiting notch, and the pressing end of the pressing rod 432 is arranged toward the bottom of the cavity 41 .

[0072] Specifically, a cover plate is provided at one end of the pressing rod 432 close to the bottom of the cavity 41 to reduce the pressure when the pressing rod 432 squeezes the concrete sample, thereby avoiding damage to the concrete sample during the test and affecting the final test data.

[0073] From the above description, it can be seen that by providing a hanging ear 44 with a limiting notch at the opening of the cavity 41, it is possible to achieve quick disassembly and assembly of the pressing assembly 43, and when the pressing rod 432 of the pressing assembly 43 hits the concrete sample, it can serve as a supporting point for the support rod 431, so that the pressing rod 432 can press the concrete sample more stably, thereby ensuring the reliability of the anti-permeability performance test and avoiding the problem of pressure relief.

[0074] Further, an elastic element is provided at the bottom of the cavity 41;

[0075] The expansion and contraction direction of the elastic element is consistent with the depth direction of the cavity 41 .

[0076] As can be seen from the above description, when the impermeability test is completed and the pressure applied by the pressing assembly 43 on the concrete sample is removed, the concrete sample can be pushed out of the cavity 41 during the recovery of the elastic element, so that it is convenient for the staff to take out the tested concrete sample, thereby indirectly improving the testing efficiency. The elastic element can be any commercially available elastic device, such as a linear spring.

[0077] Further, the water tank 1 is provided with a water level detector 11;

[0078] The detection end of the water level detector 11 is located inside the water tank 1;

[0079] The distance between the water outlet of the water tank 1 and the bottom of the water tank 1 is smaller than the distance between the detection end of the water level detector 11 and the bottom of the water tank 1 .

[0080] From the above description, it can be seen that the water level detector 11 can effectively remind the staff to replenish water into the water tank 1 in time, so as to avoid the normal progress of the anti-permeability performance test being affected by too little water in the water tank 1.

[0081] Furthermore, the water tank 1 also includes a temperature detector and a heating device;

[0082] The detection end of the temperature detector and the heating end of the heating device are both located inside the water tank 1 .

[0083] From the above description, it can be seen that through the cooperation between the temperature detector and the heating device, the staff can change the temperature of the water body to simulate different working conditions, so that the data obtained from the concrete impermeability test is more authentic.

[0084] Furthermore, the above-mentioned concrete anti-permeability performance testing device also includes a filter;

[0085] The water inlet of the filter is connected to the water outlet of the water tank 1;

[0086] The water outlet of the filter is communicated with the water inlet of the pump body 2.

[0087] From the above description, it can be seen that during the test, part of the water body will fully contact the concrete sample. Therefore, after the test, this part of the water body will flow back to the water tank 1 together with the sand. By setting a filter, it can be prevented that during the next test, the water body transfers the sand to the pump body 2 or the booster device 3, thereby damaging the internal parts of the water pump and the booster device 3, and thus shortening the overall service life of the device.

[0088] Furthermore, the above-mentioned concrete anti-permeability testing device also includes a cabinet structure 6;

[0089] The anti-seepage detection chamber 4 is arranged outside the cabinet structure 6;

[0090] The water tank 1 , the pump body 2 and the pressure boosting device 3 are arranged inside the cabinet structure 6 .

[0091] From the above description, it can be seen that setting the water-resistance test chamber 4 outside the cabinet structure 6 can not only facilitate the staff to place the concrete sample, but also enable the cabinet structure 6 to effectively support the water-resistance test chamber 4, thereby ensuring the stability of the test process; at the same time, setting the water tank 1, the pump body 2 and the booster device 3 inside the cabinet structure 6 can play a sufficient protective role and avoid damage to the equipment due to the impact of external forces.

[0092] The concrete anti-permeability performance testing device of the utility model can assist the detection work of the anti-permeability performance of concrete samples.

[0096] The water tank 1 is provided with a water level detector 11, a temperature detector and a heating device; the detection end of the water level detector 11 is located inside the water tank 1; the distance between the water outlet of the water tank 1 and the bottom of the water tank 1 is smaller than the distance between the detection end of the water level detector 11 and the bottom of the water tank 1; the detection end of the temperature detector and the heating end of the heating device are both located inside the water tank 1.

[0097] The working principle of the utility model is as follows: first, a concrete sample to be tested is placed in the cavity 41, and the support rod 431 is engaged with the limiting notch on the hanging ear 44, and the pressing rod 432 is rotated at the same time, so that the pressing rod 432 drives the concrete sample to move to the bottom of the cavity 41 to squeeze the sealing member 42, so that the sealing member 42 fills the gap between the cavity 41 and the concrete sample; then, the pump body 2 and the boosting device 3 are started by the controller, and after the pipeline is completely filled with water, the second stop valve is closed, so that the water pressure in the anti-seepage detection cavity 4 is continuously increased with the cooperation of the boosting device 3 and the second stop valve; when the pressure value reaches the specified value, the first stop valve, the boosting device 3 and the pump body 2 are closed in turn by the controller, so that the water pressure in the pipeline is maintained at a high pressure state that meets the test requirements; after the test work is completed, the second stop valve is opened again to allow the water in the pipeline to flow back to the water tank 1, thereby completing the anti-seepage performance test of the concrete.

[0098] In summary, the utility model provides a concrete anti-seepage performance testing device. When working, the second stop valve is in a closed state, and the pump body guides the water in the water tank to the boosting device, so that the water pressure in the anti-seepage detection chamber is continuously increased under the cooperation of the boosting device and the second stop valve. When the pressure value reaches the specified value, the first stop valve, the boosting device and the pump body are closed in sequence by the controller, so that the water pressure in the pipeline is maintained in a high-pressure state that meets the test requirements. Compared with the existing concrete anti-seepage performance testing device, high water pressure can be applied to the surface of the concrete sample to be tested during the whole test process, so that the anti-seepage performance of the concrete sample is always in a limit state, so that the anti-seepage ability of the concrete sample can be reflected to the greatest extent, and the test efficiency can be indirectly improved. In addition, multiple groups of independent pipe groups are set, and it is ensured that each pipe group is connected to the first stop valve and the anti-seepage detection chamber at the same time. When a pipe group has a connection problem with the anti-seepage detection chamber, other pipe groups can replace the pipe group to perform water pressurization work, thereby ensuring the stability of the concrete anti-seepage performance testing device during operation.
