Abstract
Description
Technical Field
[0001] The utility model relates to a drilling slag cleaning device, in particular to a rotary drilling slag cleaning device for a backfill area. Background Art
[0002] As we all know, bored piles refer to piles made by forming pile holes in the foundation soil by mechanical drilling, steel pipe squeezing or manual excavation at the construction site, and placing steel cages and pouring concrete in them. According to different hole-forming methods, cast-in-place piles can be divided into several categories, such as sinking pipe cast-in-place piles, bored cast-in-place piles and excavated cast-in-place piles. During the drilling process of bored piles in the backfill area, there will be a lot of scum on the hole wall. When the steel cage is hung after the pile hole is formed, it will inevitably scratch a lot of slag in the loose soil layer on the inner wall of the pile hole, and it will sink to the bottom of the hole. The excessive thickness of the sediment of bored piles has a great adverse effect on the bearing capacity and settlement of the pile foundation. The large amount of residue in the pile hole is difficult to remove, which affects the use of bored piles. In addition, the traditional drilling process is to complete the drilling by carrying rock (soil) with mud, so it is easy to form a layer of mud skin on the hole wall, which reduces the side wall friction resistance.
