Description

TECHNICAL FIELD

[0001] The utility model relates to a drilling stone taking device technical field, concretely is a simple stone taking device in small diameter deep well. BACKGROUND

[0002] When carrying out underground construction in sandy land and similar loose soil layer, the dewatering well is one of the common engineering means to lower the underground water level to maintain the stability of the construction area. However, in the dewatering well construction process, especially in the small diameter deep well, the situation of large particle size boulders or pebbles existing in the well is often encountered, which is particularly prominent in sandy land environment. Because of the loose geological structure, the boulders are difficult to exist stably, and are easy to move down or get stuck with the drilling operation, increasing the construction difficulty.

[0003] These stones in the dewatering well not only hinder the normal excavation operation of the dewatering well, but also affect the operation efficiency of the equipment, and even cause damage to the equipment. The traditional method relies on the repeated breaking of boulders by the drill bit to take them out, which not only takes a long time, but also is difficult to ensure efficient construction. Since the existing method of processing stones requires the drill bit to repeatedly act on the stones to break them, the wear of the drill bit is intensified, thereby increasing the cost of equipment maintenance and replacement. When processing stones of different particle sizes, the operation is complicated and the construction progress is slow. Therefore, it is necessary to provide a simple stone taking device in a small diameter deep well to solve the above problems. SUMMARY
