Description
Technical field
The present invention relates to drilling technique, pile foundation construction and mining construction field, be specifically related to a kind of rig.
Background technology
The relative technique of the method for air lifting reverse circulation occurred in recent years is more simple, clear hole successful, promotes very fast.The clear hole of gas lift reverse circulation is the compressed air utilizing air compressor machine, deliver in stake holes by the airduct be arranged in conduit, high pressure gas mixes with mud, the slurry gas mixture that a kind of density is less than mud is formed in conduit, slurry gas mixture rises because its proportion is little, thus form flowing, carry sediment in conduit counter go out, discharge beyond conduit.Other reacting cycle clear hole technique relatively; the ajutage of gas lift reverse circulation technique is arranged in conduit; reduce when extracting airduct and danger that reinforcing cage is cared for, more protect mud off; and gas slurry blender makes simple; slurry blender makes simple, and sediment thickness reduces, and improves bearing capacity of single pile; optimize stake footpath, reduce construction costs.Scarfing cinder speed is fast, the reduction of erection time, and mud emission amount reduces, and reduces environment pollution, reduces construction and clears processing cost.
Current gas lift reverse circulation rig has generally come with construct ground or platform by directly being supported by base, but because equipment is excessive, cause taking up an area too much in work progress, and easily cause noise pollution, sedimentation basin is fixing, is not easy mobile and again utilizes, and when restarting rig or being cut clearly, obtain vacuum state in again managing, troublesome poeration.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Stability Analysis of Structures, the air lift counter circulation drill machine rig that drilling efficiency is high.
A kind of rig of the present invention, comprises winding plant 1, steel cable 2, frame 3, aerostatic press 4, portable sedimentation basin 5, replaceable drilling rod 6 and interchangeable bit 7.The fixed pulley that frame 3 top is walked around by steel cable 2 in described drilling rod 6 upper end is connected with winding plant 1, winding plant 1 is connected with frame 3 by linkage 16, tracheae 15 on drilling rod 6 is connected with described compressor 4, drilling rod 6 by mud returning pipe 14, mud efferent duct 12 is connected with the first slush pump 10, second slush pump 11 in portable sedimentation basin 5.The first non retern valve 8 is provided with between described drilling rod 6 and drill bit 7.Described drilling rod 6 top is provided with the second non retern valve 9, and the first slush pump 10 in described portable sedimentation basin 5 is connected with the second described non retern valve 9 by mud returning pipe 14.Described drill bit 7 and the first non retern valve 8, connected by male connection or female adapter, described male connection/female adapter wall thickness increases.One side bottom of described portable sedimentation basin 5 is provided with the first slush pump 10, and described first slush pump 10 opposite side fixed end portion is provided with between the second slush pump 11, two pumps and is provided with dividing plate 19.Described dividing plate 19 is uniformly distributed the hole of with good grounds rock slag size design.
Simple in structure of the present invention, equipment dismounting is simple and easy, flexibly mobile.As an improvement of the present invention, 2 non retern valves are installed, effectively can prevent adverse current, ensure the reacting cycle of mud.Improve as of the present invention another, arranging of portable sedimentation basin 5 internal partition can block bulky grain rock slag effectively, ensures reverse circulating smooth and easy.Outer/inner nipple wall thickness between drill bit 7 and the first non retern valve 8 increases, and can effectively protect drill bit 7.
