Problems solved by technology
[0002] In building construction, construction projects such as foundation reinforcement piling and bridge pier drilling are often encountered. The traditional use of mechanical equipment to dig wells is inefficient and requires a large amount of engineering. In the existing caisson construction technology, there is no It is convenient to separate the mud and water in the underground, and because the excavation degree of the side of the caisson is uneven, the lowering efficiency of the caisson is low and it is easy to get stuck. In view of this, we propose a self-sinking drilling equipment

The invention relates to the field of construction drilling equipment, in particular to a self-sinking drilling equipment, which includes an outer cylinder and a sludge pump. An annular groove is fixed on the inner upper part of the outer cylinder, and the sludge pump communicates with the inner side of the annular groove through a mud discharge pipe. The lower part of the inner side is rotatably connected with an inner cylinder, the upper part of the inner wall of the inner cylinder is provided with a driving part, the middle part is fixed with a supercharging mechanism, and the lower part is provided with an excavating mechanism. A solid-liquid separation mechanism is arranged on the mechanism, and the solid-liquid separation mechanism is connected with the ring groove; the booster mechanism is connected with the solid-liquid separation mechanism through a water inlet pipe; This kind of self-sinking drilling equipment makes the cutter head rotate around the central axis of the inner cylinder while driving the cutter board to excavate the soil, so it can excavate the inner wall of the well evenly, which helps to improve the excavation quality, thereby improving the excavation efficiency and realizing The solid and liquid of the sludge are separated by themselves.
Description
technical field [0001] The invention relates to the field of construction drilling equipment, in particular to a self-sinking drilling equipment. Background technique [0002] In building construction, construction projects such as foundation reinforcement piling and bridge pier drilling are often encountered. The traditional use of mechanical equipment to dig wells is inefficient and requires a large amount of work. In the existing caisson construction technology, there is no It is convenient to separate the mud and water in the downhole, and because the excavation degree of the side of the caisson is uneven, the lowering efficiency of the caisson is low and it is easy to get stuck. In view of this, we propose a self-sinking drilling equipment. Contents of the invention [0003] The object of the present invention is to provide a self-sinking drilling equipment to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the abo...
