Description

Technical Field

[0001] This utility model relates to the field of concrete duct cleaning technology, and more specifically, to a system for automatic cleaning of concrete ducts for cast-in-place piles. Background Technology

[0002] Currently, the common method for cleaning concrete ducts on construction sites is to lift and remove the concrete duct after the concrete of the cast-in-place pile is poured, and then manually use water pipes to clean the concrete duct. This requires multiple people to manually rotate the concrete duct to complete the cleaning.

[0003] Manual cleaning: Currently, manual cleaning during construction requires at least two people working together, resulting in a waste of human resources. Manual cleaning typically involves removing the guide pipe after the concrete pouring of the cast-in-place piles and using a nearby water spray pipe to clean the concrete guide pipe. However, the water used for cleaning the guide pipe cannot be effectively drained or collected for recycling, causing mud on the construction site, disrupting on-site construction order, further affecting other construction processes, slowing down the construction progress, and indirectly increasing time costs.

[0004] Chinese Patent Application No. 201920841048.3 discloses a concrete conduit cleaning device, which works by vertically placing the concrete conduit and spraying water to clean it. However, when the conduit sections are too long, they cannot be placed effectively, posing a certain safety hazard. The device also requires a high degree of flatness of the site. If the site is uneven, it cannot be placed stably and may tip over when the water is rotated, causing danger. Utility Model Content

[0006] Furthermore, the automatic hose reel is mounted on a height-adjustable mounting frame. One end of the support member is mounted on the mounting frame, and the other end is mounted on one side of the circulating water tank. The horizontal position of the support member at the end of the mounting frame is higher than that at the other end of the circulating water tank, which allows the dirty water after cleaning in the concrete conduit to flow smoothly into the circulating water tank.

[0007] Furthermore, the circulating water tank is equipped with a filter screen, which can filter and recycle the dirty water after cleaning the concrete duct.

[0008] Furthermore, the circulating water pipe is located at the bottom of the circulating water tank, and a pressurized water pump is installed to transport water from the circulating water tank to the circulating water pipe.

[0009] Furthermore, the support member is provided with two pads, and the pads are provided with grooves that match the outer diameter of the concrete conduit, which can position and secure the concrete conduit.

[0010] Furthermore, the mounting frame includes a frame, a mounting base, and a baffle; the mounting base is located at the center of the frame and is used to support the automatic hose reel; the baffle is located on one side of the mounting base and connected to the frame, and can position and fix the automatic hose reel in the vertical direction.

[0011] Furthermore, a rotating nozzle is connected to the circulating water pipe. The automatic hose reel uses the contraction and unfolding of the hose to drive the rotating nozzle to reciprocate along the concrete guide pipe, and sprays the water in the circulating water pipe into the concrete guide pipe through the rotating nozzle for cleaning.

[0012] Furthermore, the automatic hose reel is connected to a conveying pulley at the hose end, and the rotating nozzle is mounted on the conveying pulley. The automatic hose reel drives the conveying pulley to reciprocate within the concrete conduit by extending and retracting its hose, thereby driving the rotating nozzle to spray water from the circulating water pipe into the concrete conduit for cleaning.

[0013] Furthermore, the automatic hose reel is connected to a rigid pipe at its hose reel end, and the rotating nozzle is located at the end of the rigid pipe.

This effectively speeds up the cleaning process, especially in situations with a tight construction schedule or a large number of long cast-in-place piles. Furthermore, this utility model provides automatic wastewater recovery and recycling, preventing muddy conditions at the construction site and ensuring uninterrupted construction. There are no specific requirements regarding the length and weight of the guide pipe sections, and there are no safety hazards during the cleaning process. Attached Figure Description

The horizontal position of the support member 1 at one end of the mounting frame 7 is higher than the height of the support member 1 at the other end of the circulating water tank 3, allowing the dirty water after cleaning in the concrete guide pipe 8 to flow smoothly into the circulating water tank 3. (Refer to...) Figure 1-2 As shown, the mounting frame 7 includes a frame 71, a mounting base 72, and a baffle 73. The mounting frame 7 is entirely made of seamless steel pipe welded together. The mounting base 72 is located at the center of the frame 71 and is used to support the automatic hose reel 2. The baffle 73 is located on one side of the mounting base and connected to the frame 71, enabling the automatic hose reel 2 to be positioned and fixed in the vertical direction. In this embodiment, the height of the mounting frame is adjustable, which facilitates control of the height of the automatic hose reel while controlling the water spray nozzle extending into the concrete duct.

[0025] Reference Figure 1 , 3 As shown, the circulating water tank 3 is equipped with a filter screen 5, which can filter and recycle the dirty water after cleaning the concrete conduit 8. Specifically, the filter screen 5 is used to filter concrete residue flowing out during the cleaning of the concrete conduit 8. This part is detachable for easy and timely cleaning of residue.

[0026] Reference Figure 1 As shown, the circulating water pipe 4 is located at the bottom of the circulating water tank 3, and the water in the circulating water tank 3 is transported to the circulating water pipe 4 by the provided pressurized water pump 6. Specifically, the provided pressurized water pump 6 can pressurize the water in the circulating water tank 3 to a level that can effectively clean the concrete, soil and other residues on the inner wall of the concrete conduit 8.

[0027] Reference Figure 1As shown, the support member 1 is provided with two pads 9, and the pads 9 are provided with grooves 91 that match the outer diameter of the concrete conduit 8, which can position and fix the concrete conduit 8, making it difficult for the concrete conduit 8 to slide and preventing the concrete conduit 8 from sliding and shifting, thus further ensuring the safety during the cleaning process.

[0028] In this embodiment, a rotating nozzle is connected to the circulating water pipe 4. The automatic hose reel 2 drives the rotating nozzle to reciprocate along the concrete conduit 8 by retracting and unfolding the hose, and sprays the water in the circulating water pipe 8 into the concrete conduit 8 through the rotating nozzle for cleaning.

[0029] In this embodiment, the automatic hose reel 2 has a conveying pulley connected to its hose reel end, and the rotating nozzle is mounted on the conveying pulley.

[0032] In summary, the system for automatic cleaning of concrete guide pipes for cast-in-place piles provided by this utility model has the following beneficial technical effects: It utilizes conventional steel pipes and plates, which are easily processed and manufactured on-site, making the manufacturing process simple and convenient. Furthermore, this utility model provides an automatic wastewater recycling and reuse function, avoiding muddy conditions at the construction site. There are no explicit requirements regarding the segment length or weight of the guide pipe. An automatic pipe reel drives a rotating nozzle, allowing the nozzle to penetrate deep into the guide pipe for rotating water spraying, thus achieving the cleaning effect. This effectively accelerates the cleaning speed of the guide pipe, especially in situations with a dense construction period or a large number of long cast-in-place piles. Moreover, the automatic wastewater recycling and reuse function prevents muddy conditions at the construction site and does not disrupt on-site construction order. There are no explicit requirements regarding the segment length or weight of the guide pipe, and there are no safety hazards during the cleaning process.
