Description

Technical Field

[0001] This utility model relates to the field of concrete freeze-thaw technology, and in particular to a vacuum water absorption device for the external surface of concrete. Background Technology

[0002] The water-cement ratio is the weight ratio of water to cement used in mixing cement paste, mortar, and concrete. The water-cement ratio affects the rheological properties of concrete, the cohesive structure of the cement paste, and its density after hardening. Therefore, the water-cement ratio is a key parameter determining the strength and other physical and mechanical properties of concrete. To reduce the water-cement ratio, vacuum dehydration is used in concrete construction. A vacuum dehydrator removes excess water and air from concrete with a high water-cement ratio, thus achieving the desired ideal water-cement ratio to ensure the concrete's strength, density, and wear resistance.

[0003] However, existing concrete vacuum water suction devices have problems such as inconvenience in storing the cover, easy trampling after use, and inconvenience in reeling in the water pipe. Utility Model Content

The threaded ring is then connected to the first hose, and the vacuum pump body is started to extract excess water and air from the concrete. The sealing ring also enhances the sealing performance of the cover, thereby ensuring the strength, density, and wear resistance of the concrete. After use, the worker places the cover into the collection box and uses bolts to limit the edge of the cover. Then, the handle is turned by hand to rotate the rotating rod to roll up the cover, making it easy to store and organize.

[0012] By adopting the above technical solution, the first hose can also be wound up by turning the handle, which avoids hose damage and facilitates transportation.

[0013] A further feature of this invention is that a handle is fixedly connected to one end of the round rod, and a protective sleeve is fixedly connected to the outside of the handle.

[0014] By adopting the above technical solution, the protective cover can protect the handle.

[0015] A further feature of this invention is that a connecting rod is rotatably connected inside the support base, and a handle is fixedly connected to the surface of the connecting rod.

[0016] By adopting the above technical solution, the handle can be easily pulled by staff to move the device, making it convenient for transportation and saving time and effort.

[0017] A further feature of this invention is that the number of holes is four, and the four holes are arranged in a rectangular array on the upper surface of the base.

[0018] By adopting the above technical solution, the design of multiple holes improves the fixation effect on the base.

[0019] A further feature of this invention is that one end of the bolt is threadedly connected to a pressure plate, and one side of the pressure plate is fixedly connected to a rubber sheet.

Then, the vacuum pump body is started to extract excess water and air from the concrete. The sealing ring can also enhance the sealing performance of the cover, thereby ensuring the strength, density, and wear resistance of the concrete. After use, the staff places the cover into the collection box and uses bolts to limit the edge of the cover. Then, the handle is turned by hand to drive the rotating rod to roll up the cover, which is convenient for storage and organization, and avoids damage to the cover due to trampling or other reasons, which may affect the next use.
