Description
Technical Field
[0001] The invention relates to the technical field of concrete quality detection, and in particular to a device for detecting the quality of deep-water cap bottom concrete. Background Art
[0002] Deepwater cap refers to the cap structure in deeper waters in the construction of bridges and other projects. It provides stable support for the piers or other structures of the bridge and transfers the load of the superstructure to the foundation. The bottom sealing of deepwater cap is one of the key links in the construction of deepwater cap in the construction of bridges and other projects. In deepwater environment, the bottom sealing concrete can effectively prevent water from entering the bottom of the cap, creating a dry working environment for the cap construction. At the same time, the bottom sealing concrete, pile foundation and steel cofferdam (or caisson, casing) jointly bear the load of the cap and the superstructure, improving the stability of the entire structure. The quality inspection of the bottom sealing concrete of deepwater cap is very important in the concrete construction of deepwater cap. The inspection of the thickness of the bottom sealing concrete usually adopts the drilling detection method, which can directly reflect the sealing, thickness and height of the concrete bottom sealing. However, the existing drilling detection method will directly destroy the already formed concrete structure and cause certain damage when drilling holes in concrete. It is difficult to drill holes in various places of the bottom concrete, resulting in the inability to fully reflect the thickness of the entire bottom concrete. Therefore, we propose a deep-water cap bottom concrete quality detection device. Summary of the invention

The outer surface of the linkage rod located at the top of the spiral plate is fixedly connected with a frame-shaped scraper rod, and the inner side of the frame-shaped scraper rod is fixedly connected with a corrugated stirring bar. When the corrugated stirring bar rotates, the concrete on the top of the spiral plate is fully stirred, so as to prevent the concrete on the top of the spiral plate from being hardened in the hollow drill bit after being left to stand for a long time, which makes it difficult to use and inconvenient to handle; There are three blocking components, and the three blocking components are evenly distributed on the outer surface of the linkage rod, and the outer side of the circular baffle is fixedly connected to the inner wall of the hollow drill bit; There are three arc-shaped feed holes, which are evenly distributed on the outer surface of the hollow drill bit; there are three discharge holes, which are evenly distributed on the outer surface of the hollow drill bit.

The top of the extension spring is fixedly connected to the outer surface of the outer inclined sleeve, and the top of the long through rod passes through the outer inclined sleeve and is slidably connected to the outer inclined sleeve.

When the hollow drill bit 301 is drilling, the outer inclined sleeve 502 on the outside is always covered and protected. When the hollow drill bit 301 rotates, the outer inclined sleeve plate 6 drives the bottom extension spring 501 and the outer inclined sleeve 502 to rotate together through the long penetration rod 503. When the hollow drill bit 301 gradually drills downward, the outer inclined sleeve 502 is always in contact with the concrete plane. When the outer inclined sleeve plate 6 moves downward with the hollow drill bit 301, it will The spring 501 is compressed, and the outer oblique sleeve 502 rotates, driving the inner oblique push plate 505 and the top hard arc brush 504 to rotate together. When the oblique push plate 505 rotates, it pushes the debris and stones generated by the surrounding drilling to the outside and moves to a position away from the drilling hole. When the hollow drill bit 301 moves up after drilling, the hard arc brush 504 is always in contact with the outer surface of the hollow drill bit 301. When the outer oblique sleeve 6 moves up with the hollow drill bit 301, the compression of the extension spring 501 is released. After the extension spring 501 loses pressure, it stretches. The hard arc brush 504 rubs and cleans the outer surface of the moving hollow drill bit 301. The long penetration rod 503 fixedly connected to the outer oblique sleeve 502 penetrates the outer oblique sleeve 6 to limit the outer oblique sleeve 502 elastically connected by the extension spring 501.
