Drill rod spiral composite drilling machine for building

Abstract

The invention discloses a drill rod spiral composite drilling machine for a building. The machine comprises a cart body; a stand column is arranged on the vehicle body; a limiting sleeve is arranged on a fixing block; the middle part of the limiting sleeve is sleeved with a screw mechanism; a rod body is movably inserted into the middle part of the limiting sleeve; a rotary excavating drilling bit, a first baffle ring, a second baffle ring, the limiting groove and the groove are sequentially formed in the surface of the rod body from bottom to top; a lifting ring is arranged in the groove; a threaded hole is formed in the surface of the top end of the rod body; the top of the rod body is fixedly connected with a cover plate through the threaded hole and the connecting screw rod in the threaded hole; when the rotary excavating drill bit and the rod body with the structure are used for forming a hole, the hole can be drilled; the soil body at the bottom is loose; when concrete is pouredthrough external concrete filling equipment, loose soil moves upwards under the spiral effect, so that the hole wall is smooth and firm, the hole forming effect is very good, hole collapse is avoided,and the hole wall is smooth under the effect of underground water; when the concrete is poured through the external concrete filling equipment, the friction resistance is very small when the rod bodydrives the soil upwards, and the power load of the driving motor is greatly reduced.

Description

technical field [0001] The invention relates to a drill pipe, in particular to a drill pipe helical composite drilling machine and a construction process. Background technique [0002] Drilling rig is a complex set of machines, which is composed of machines, units and mechanisms. Drilling rig is a mechanical device that drives drilling tools to drill underground to obtain physical geological data during exploration or mineral resource development. It is also called drilling rig. The function is to drive the drilling tool to break the rock at the bottom of the hole, and to lower or raise the drilling tool in the hole. Drilling rigs are also used in the construction of concrete piles. During the construction of existing concrete piles, due to the unstable expansion rate and inclination of the drill pipes, the construction cannot be carried out continuously, and interval piling drilling is required. And when the inclination is too large, the clamping pile reinforcement cage wi...

Problems solved by technology

Drilling rigs are also used in the construction of concrete piles. During the construction of existing concrete piles, due to the unstable expansion rate and inclination of the drill pipes, the construction cannot be carried out continuously, and interval piling drilling is required. And when the inclination is too large, the clamping pile reinforcement cage will be stuck and cannot go down to the bottom, which will affect the work efficiency and work quality of the staff. Therefore, we have improved this and proposed a drill pipe helical composite drilling rig and construction technology

[0003] Further, in view of the increasingly serious desertification of border land in our country, experts put forward suggestions of returning farmland to forests and man-made desert oasis buildings. Although these measures have certain effects, partly due to insufficient equipment and equipment research and development, the control effect is limited. The above Insufficient research and development of equipment and equipment is reflected in the fact that the construction equipment in the normal construction site cannot be used in the desert area; after analysis, it can be known that the size and weight of ordinary construction equipment in the desert area are not conducive to deployment and use, and are not conducive to escape. Moreover, the climate in the desert The conditions and environment are harsh, and the cleaning of the construction site is more time-consuming, laborious, and inefficient than the normal cleaning of the construction site. This is one of the reasons why artificial engineering is rarely seen in the desert.

[0004] The Chinese patent with authorized notification number CN 208016291U discloses a device for improving Gobi afforestation, which can complete simple drilling and pit processing, and it can facilitate the planting of different trees, but the desert oasis renovation project is not a simple renovation project , need other medium and heavy machinery better suited for the desert oasis area
