[0001] The invention relates to the technical field of concrete anti-seepage detection, and in particular to a construction material anti-seepage detection device and a detection method thereof. Background Art

[0002] As a basic material widely used in the construction industry, the impermeability of concrete is crucial to ensure the safety and durability of buildings. The impermeability of concrete not only characterizes the ability of concrete to resist water flow, but also affects the concrete's resistance to carbonization and chloride ion penetration. At present, the method of evaluating the impermeability of concrete mainly relies on traditional water pressure tests and empirical judgment.

[0003] According to GB / T 50082 Standard for Test Methods for Long-term Performance and Durability of Ordinary Concrete, the test methods for concrete water penetration resistance are mainly divided into the water penetration height method and the step-by-step pressurization method, both of which require the use of a water penetration detection device. In the process of testing concrete test blocks (cylindrical concrete blocks) using traditional water penetration detection devices, the installation of the concrete test blocks is cumbersome and requires multiple operations, making the detection inconvenient and the detection efficiency low. For this reason, the present invention provides an easy-to-use construction material water penetration detection device and a detection method thereof. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a construction material anti-seepage detection device and a detection method thereof, which solves the problem that when traditional anti-seepage detection devices are used to detect concrete test blocks (cylindrical concrete blocks), the installation of concrete test blocks is cumbersome and requires multiple operations, making the detection inconvenient and the detection efficiency low.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A construction material anti-seepage detection device, comprising:

[0007] A box body, wherein a plurality of detection modules are arranged on the top of the box body;

[0008] A pressure water supply system, which is arranged inside and on the side of the box body, and is used to supply pressure liquid to a plurality of detection modules;

[0009] The detection module comprises:

[0010] An annular bottom plate, the annular bottom plate is fixedly mounted on the top of the box body, and a plurality of guide frames distributed in an annular array are fixedly connected to the top of the annular bottom plate;

[0011] An annular bracket, wherein the annular bracket is slidably mounted on the guide frame, and a plurality of push bars distributed in an annular array are fixedly connected to the top of the annular bracket;

[0012] An annular frame, the annular frame is fixedly mounted on the top of the guide frame, a mounting seat is provided at the bottom of the annular frame, and the mounting seat corresponds to the push bar;

[0013] A "Z"-shaped clamp, the middle portion of which is rotatably mounted on the inner side of the mounting seat via a shaft;

[0014] An upward push assembly, the upward push assembly is installed in the box body, and the upward push assembly is used to drive the annular bracket to slide along the guide frame;

[0015] A nozzle assembly, wherein the liquid inlet interface of the nozzle assembly is connected to the water outlet end of the pressure water supply system, the opening end of the nozzle assembly faces upward, the nozzle assembly is located on the inner side of the annular bracket, an outer convex plate is fixedly provided on the outer side of the nozzle assembly, and an inner convex plate is fixedly provided on the inner side of the annular bracket;

[0016] When the nozzle assembly rotates to a first position range, the inner convex plate overlaps with the outer convex plate;

[0017] When the spray head assembly is rotated to a second position range, the inner convex plate is staggered with the outer convex plate.

[0018] Another object of the present invention is to provide a method for detecting the impermeability of construction materials, using the above-mentioned device for detecting the impermeability of construction materials, which specifically comprises the following steps:

[0019] S1, obtaining a concrete test block;

[0020] S2, adjust the nozzle assembly to be in the second position range, and adjust the "Z"-shaped clamp to be in a vertical state, control the push-up assembly to push the annular bracket and the push strip to the top, place the concrete detection block in the area above the annular bracket and inside the push strip, control the push-up assembly to drive the annular bracket and the push strip to the bottom, and the concrete detection block moves down with the annular bracket, and then adjust the nozzle assembly to be in the first position range, and make the "Z"-shaped clamp in a non-vertical state, control the push-up assembly to push the annular bracket and the push strip to move upward, because the inner convex plate overlaps the outer convex plate, the annular bracket will drive the nozzle assembly to move upward, so that the nozzle assembly is against the lower end surface of the concrete detection block, and the top end of the push strip is against the part of the "Z"-shaped clamp close to the outside, so that the part of the "Z"-shaped clamp close to the inside limits the top of the concrete detection block;

[0021] S3. Control the pressure water supply system to supply pressure water to the nozzle assembly. Keep the pressure water in the sealed cavity formed by the top of the nozzle assembly and the lower end surface of the concrete detection block for a period of time. After the test is completed, observe the water seepage condition of the upper end surface of the concrete detection block.

[0022] The present invention provides a construction material anti-seepage detection device and a detection method thereof, which have the following beneficial effects:

[0023] 1. The present invention improves the detection module, which includes an annular bottom plate, an annular bracket, an annular frame, a "Z"-shaped clamp, an upward push assembly, a nozzle assembly and other structures. When the nozzle assembly is rotated to a first position range, the inner convex plate and the outer convex plate overlap, and the annular bracket can drive the nozzle assembly to squeeze the bottom end of the concrete detection block to form a chamber for supplying pressurized water, so that the detection sample can be completed quickly; when the nozzle assembly is rotated to a second position range, the inner convex plate and the outer convex plate are staggered, and the nozzle assembly is not restricted by the upward and downward movement of the annular bracket. The loading and disassembly of the concrete detection block can be completed conveniently by relying on the annular bracket.

[0024] 2. The present invention designs a "Z"-shaped clamp and rotatably mounts it on a mounting seat of the annular frame. The "Z"-shaped clamp can be in a vertical state and does not interfere with the up and down movement of the push bar. The "Z"-shaped clamp can be in a non-vertical state, and the push bar pushes the outer part of the "Z"-shaped clamp upward, so that the inner part of the "Z"-shaped clamp presses the concrete detection block, thereby facilitating the fixing of the concrete detection block.

[0025] 3. The present invention designs a plastic sleeve which is sleeved on the outside of the concrete detection block and uses an upper protective member and a lower protective member to protect the edge of the concrete detection block, thereby preventing the concrete detection block from breaking during the extrusion process, which makes it more troublesome to clean up in the next experiment.
