[0002] Precast concrete parts refer to concrete components manufactured in factories or precast sites and then transported to the site for installation and assembly. These precast parts can be of various shapes and sizes, such as beams, columns, slabs, walls, etc. Precast concrete parts are widely used in construction and infrastructure projects. When purchasing, using and producing precast concrete parts, testing equipment will be used to test their anti-seepage performance.

[0003] Authorization announcement No. CN217212153U discloses a device for detecting the impermeability of precast concrete parts for construction, comprising a base, a mounting plate fixedly mounted on the top of the base, an adjusting mechanism provided on the inner bottom of the mounting plate, a fixing mechanism provided inside the mounting plate, and a controller fixedly mounted on the top of the base. The device for detecting the impermeability of precast concrete parts for construction can effectively fix the precast concrete parts through the cooperation of the adjusting mechanism and the fixing mechanism, thereby solving the problem that the structure of some existing devices is fixed, and the size of the precast concrete parts is also fixed, resulting in the inability to effectively fix them during the impermeability test, causing water to seep out from the gaps, thereby affecting the accuracy of the test results, thereby ensuring the accuracy of the test results and improving the practicability of the device.

[0004] The existing construction concrete precast anti-permeability testing device has the following disadvantages: the overall structure is large, the concrete precast needs to be moved to the installation plate before the concrete precast can be tested, and it cannot be carried, so as to detect the concrete precast. To this end, we propose a concrete precast anti-permeability testing device. Summary of the invention

[0005] The main purpose of the utility model is to provide a device for detecting the anti-seepage of prefabricated concrete parts, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] Furthermore, a sealing sleeve is glued to the inner side of the rod sleeve, and the connecting rod passes through the sealing sleeve.

[0009] Furthermore, exhaust grooves are evenly spaced through the top of the transparent cylinder, and through holes are evenly spaced through the top of the transparent cylinder; when the piston plate moves upward, gas in the transparent cylinder is discharged through the exhaust grooves.

[0010] Furthermore, a scale is engraved on one side of the transparent cylinder, and pedals are fixed to both ends of the transparent cylinder by bolts; after the transparent cylinder is placed on the prefabricated concrete part, the pedals are stepped on to fix the transparent cylinder.

[0011] Furthermore, the bottom end of the water inlet one-way valve is connected to the inside of the transparent cylinder through a pipeline, and the detection end of the pressure gauge is located inside the transparent cylinder.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Place the transparent cylinder on the concrete prefabricated part to be tested, pour clean water into the water cylinder, open the valve to allow the clean water in the water cylinder to flow into the transparent cylinder through the water inlet check valve, and the clean water entering the transparent cylinder flows out through multiple through holes to perform anti-seepage test on the concrete prefabricated part. Observe the scale to understand the water level in the transparent cylinder. If the water level drops, it means that water seepage occurs in the concrete prefabricated part.

Implementation

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, a device for detecting the anti-seepage of precast concrete parts comprises a transparent cylinder 1, a water cylinder 2 and a rod sleeve 3, an air guide hood 5 is glued inside the transparent cylinder 1, an air intake check valve 6 is connected to the bottom of the air guide hood 5 through a threaded groove, a rod sleeve 3 is hot-melt connected to the top of the transparent cylinder 1, a connecting rod 4 is sleeved through the inside of the rod sleeve 3, a piston plate 7 is fixed to the bottom end of the connecting rod 4 located inside the transparent cylinder 1 through a flange, a water cylinder 2 is installed on one side of the transparent cylinder 1 through a mounting frame, a valve 13 is connected to the bottom of the water cylinder 2 through a threaded groove, a water intake check valve 14 is connected to the bottom end of the valve 13 through a pipeline, a pressure gauge 16 is connected to the end of the transparent cylinder 1 away from the water cylinder 2 through a threaded groove, a sealing ring 8 is glued to the bottom end of the outer side of the transparent cylinder 1, a counterweight ring 9 is embedded in the sealing ring 8.

[0020] Among them, Figure 2 As shown, a sealing sleeve 10 is glued to the inner side of the rod sleeve 3, and the connecting rod 4 passes through the sealing sleeve 10. The sealing sleeve 10 seals between the rod sleeve 3 and the connecting rod 4 to prevent dust, impurities, etc. from falling into the transparent cylinder 1.

[0021] Among them, Figure 2 As shown, the top of the transparent cylinder 1 is equidistantly penetrated with exhaust grooves 12 , and the top of the transparent cylinder 1 is equidistantly penetrated with through holes 11 , and the through holes 11 are opened to facilitate the outflow of clean water in the transparent cylinder 1 .

[0022] Among them, Figure 1 As shown, a scale 15 is engraved on one side of the transparent cylinder 1, and pedals 17 are fixed to both ends of the transparent cylinder 1 by bolts. The setting of the scale 15 is convenient for personnel to observe and understand the changes in the water level in the transparent cylinder 1.

[0023] Among them, Figure 1As shown, the bottom end of the water inlet check valve 14 is connected to the inside of the transparent cylinder 1 through a pipeline, and the detection end of the pressure gauge 16 is located inside the transparent cylinder 1. The pressure gauge 16 can detect and display the pressure inside the transparent cylinder 1.

[0024] It should be noted that the utility model is a device for detecting the anti-seepage of precast concrete parts. When working, a person places the transparent cylinder 1 on the precast concrete part to be detected, and steps on the pedal 17 to make the sealing ring 8 seal between the transparent cylinder 1 and the precast concrete part. A counterweight ring 9 is arranged inside the sealing ring 8, which can prevent the transparent cylinder 1 from tipping over due to its own weight. Clean water is poured into the water cylinder 2, and the valve 13 is opened to make the clean water in the water cylinder 2 flow into the transparent cylinder 1 through the water inlet check valve 14. The clean water entering the transparent cylinder 1 passes through multiple passages. The liquid flows out of the hole 11 and falls on the precast concrete part. The water level in the transparent cylinder 1 is understood by observing the scale 15. After a period of stillness, if the water level drops, it indicates that the precast concrete part has water seepage. If the water level does not drop, the personnel hold the connecting rod 4 and push the piston plate 7 downward. The piston plate 7 moves downward to push the gas through the air guide cover 5 and the air inlet check valve 6 to the transparent cylinder 1 at the bottom of the air guide cover 5, and the transparent cylinder 1 is given pressure to push the clean water to penetrate into the precast concrete part, so as to detect the anti-seepage ability of the precast concrete part.
