Description

Technical Field

[0001] The utility model belongs to the technical field of cast-in-place piles, in particular to a concrete pouring stopping device for cast-in-place piles. Background Art

[0002] A bored pile refers to a pile made by drilling a hole in place and pouring concrete or reinforced concrete. Bored piles are widely used in construction because they have the advantages of no vibration, no soil squeezing, low noise, and are suitable for use in densely built urban areas. During the pouring process of bored piles, concrete needs to be poured into the pouring hole, and after the concrete pouring is completed, a stop device needs to be controlled to prevent the concrete from continuing to be discharged, thereby effectively avoiding the waste of concrete.

[0003] After searching, a patent document with patent announcement number CN218668578U discloses a concrete pouring device, including a hopper, a discharge pipe, a cover plate and a blocking plate. The hopper is used to connect with the swing arm of the excavator; the discharge pipe is connected to the bottom of the hopper, and a discharge port is provided at the lower end of the discharge pipe; the cover plate blocks the outside of the discharge port, and a mounting boss protruding outward is provided on the outer end surface of the cover plate, and a connecting hole connected to the inside of the discharge pipe is penetrated on the mounting boss; the blocking plate is rotatably connected to the cover plate, and is used to block or avoid the connecting hole; wherein, a scraper strip is provided on the outer end surface of the cover plate for contacting with the inner end surface of the blocking plate to clean the concrete on the blocking plate. The concrete pouring device provided by it can make the scraper strip scrape and clean the concrete adhered to the inner end surface of the blocking plate during the rotation of the blocking plate, so as to avoid the interference of the blocking plate with the discharge pipe during the rotation process.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the existing concrete pouring device, during use, the positioning block and the limit block are used to cooperate with each other to limit the position of the fully opened or fully closed plugging plate, thereby realizing the discharge or stop of the concrete inside the hopper. However, it is not convenient to adjust the discharge amount of concrete according to the actual needs of the cast-in-place pile pouring, thereby limiting the adjustment range of the concrete discharge amount, thereby reducing the scope of use and reducing practicality.

[0006] 2. In the existing concrete pouring device, during use, when the sealing plate is rotated and adjusted, the scraper plate cleans the concrete on the side wall of the sealing plate, thereby effectively preventing the residual concrete on the sealing plate from solidifying and blocking the adjustment of the position of the sealing plate, thereby not affecting the discharge of concrete inside the hopper. However, after the sealing plate is rotated and adjusted to open, the sealing plate is completely exposed, and then there will be debris on the sealing plate, such as dust, catkins and leaves, etc., and even after the sealing plate is closed, the debris on the sealing plate will enter the interior of the bending pipe, thereby reducing the quality of the concrete inside the bending pipe.

[0007] To this end, we provide a concrete pouring stop device for bored piles to solve the above problems. Utility Model Content
