Description

Technical Field

[0001] The invention relates to the technical field of concrete conduit cleaning, and in particular to a system for automatically cleaning a concrete conduit of a cast-in-place pile. Background Art

[0002] At present, the common cleaning method for concrete ducts on construction sites is to lift and remove the concrete ducts after the concrete pouring of the bored piles is completed, and manually use a water pipe to insert into the concrete ducts for cleaning, and multiple people are required to manually rotate the concrete ducts to complete the cleaning.

[0003] Manual cleaning: Currently, manual cleaning requires at least two people to cooperate with each other, which will cause a waste of human resources. Manual cleaning usually involves removing the conduit after the concrete pouring of the bored pile is completed, and then using a nearby water spray pipe to clean the concrete conduit. The water from the conduit cannot be effectively discharged or collected for recycling, causing mud on the construction site, affecting the on-site construction order, further affecting the development of other construction processes, slowing down the construction progress, and indirectly increasing the time cost.

[0004] Chinese patent application No. 201920841048.3 discloses a concrete pipe cleaning device, the principle of which is to place the concrete pipe vertically and spray water for cleaning. When the length of the pipe section is too long, it cannot be effectively placed, which poses a certain safety hazard. It has high requirements for the flatness of the site. If the site is uneven, it cannot be effectively and stably placed, and it is easy to overturn when rotating and spraying water, causing danger. Summary of the invention

[0006] Furthermore, the automatic hose reel is mounted on a height-adjustable mounting frame, one end of the bearing 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 bearing member at one end of the mounting frame is higher than the height of the other end of the circulating water tank, so that the dirty water after cleaning in the concrete conduit can flow into the circulating water tank.

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

[0008] Furthermore, the circulating water pipe is arranged at the bottom side of the circulating water tank, and the water in the circulating water tank is transported to the circulating water pipe through a pressure water pump.

[0009] Furthermore, the bearing member is provided with two cushions, and the cushions are provided with grooves matching the outer diameter of the concrete conduit, so as to position and fix the concrete conduit.

[0010] Furthermore, the mounting frame includes a frame body, a mounting base and a baffle; the mounting base is arranged at the center position of the frame body, and is used to carry the automatic hose reel; the baffle is arranged on one side of the mounting base and is connected to the frame body, 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, and the automatic hose reel drives the rotating nozzle to reciprocate along the concrete conduit by contracting and unfolding its hose reel, and sprays the water in the circulating water pipe into the concrete conduit through the rotating nozzle for cleaning.

[0012] Furthermore, the reel end of the automatic hose reel is connected to a conveying pulley, and the rotating nozzle is arranged on the conveying pulley. The automatic hose reel drives the conveying pulley to reciprocate in the concrete conduit through the extension and expansion of its hose, thereby driving the rotating nozzle to spray the water in the circulating water pipe into the concrete conduit for cleaning.

[0013] Furthermore, the reel end of the automatic hose reel is connected to a hard pipe, and the rotating nozzle is arranged at the end of the hard pipe. The automatic hose reel drives the hard pipe to reciprocate in the concrete conduit through the extension and expansion of its reel, thereby driving the rotating nozzle to spray the water in the circulating water pipe into the concrete conduit for cleaning.

[0014] Furthermore, the filter screen is a steel wire filter screen, which is detachably mounted on the top of the circulating water tank and can filter dirty water after cleaning in the concrete conduit.

[0015] The system provided by the present invention is for automatically cleaning the concrete conduit of a bored pile, and has the following advantages: an automatic hose reel is used to drive a rotating spray head, so that the spray head penetrates into the conduit to perform a rotating spray, thereby achieving a cleaning effect, and effectively speeding up the conduit cleaning speed when the construction period is relatively intensive or the number of bored piles is large and the pile length is long; the present invention also provides a function of automatically recovering and recycling cleaning waste water, thereby avoiding muddying of the construction site and not affecting the on-site construction order; there are no clear requirements for the segmented length and weight of the conduit, and there are no safety hazards during the cleaning process.
