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 work. 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 building drilling equipment, in particular to self-sinking drilling equipment. The self-sinking drilling equipment comprises an outer barrel and a sludge pump, wherein an annular groove is fixed to the upper part of the inner side of the outer barrel, the sludge pump communicates with the inner side of the annular groove through a sludge discharge pipe, and the lower part of the inner side of the outer barrel is rotationally connected with an inner barrel through a fixed shaft; a driving part is arranged on the upper part of the inner wall of the inner barrel, a pressurizing mechanism is fixed on the middle part of the inner wall of the inner barrel, a digging mechanism is arranged on the lower part of the inner wall of the inner barrel, and the driving part is in transmission connection with the digging mechanism, the outer barrel and the pressurizing mechanism; and a solid-liquid separating mechanism is arranged on the digging mechanism and connected with the annular groove, and the pressurizing mechanism is connected with the solid-liquid separating mechanism through a water inlet pipe and connected with the digging mechanism through a wateroutlet pipe. According to the self-sinking drilling equipment, a cutter head rotates around the central axis of the inner barrel while driving the cutter plate to dig soil, so that the inner wall ina well can be dug uniformly, the digging quality is improved, the digging efficiency is improved, and solid-liquid automatic separation of sludge is realized.
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 piling for foundation reinforcement and drilling for bridge pier columns 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 kind of self-submerging drilling equipment, to solve the problems raised in the above-mentioned background technology. [0004]...
