Description
Technical field
The utility model relates to a kind of boring slip casting retaining wall drilling rig, is mainly used in the engineering investigation of prose style free from parallelism gravelly soil (such as refuse dump, spoil area, loose rock dam etc.), belongs to the geotechnical engineering field.
Background technology
The normal drilling tool that adopts or conventional drilling tool in the engineering investigation, its main function is: 1, transmit drill pressure and rotary torque to drill bit in drilling process; 2, at the bottom of the hole, carry drilling fluid; 3, guarantee the direction of boring, prevent its off-centre of in drilling process, holing.But concerning prose style free from parallelism gravelly soil material, comparatively loose owing to its gravelly soil by the variable grain particle size forms, and a large amount of spaces is arranged, so in the prospecting process, very easily cause the phenomenon that collapses the hole and leak.Some rubble soil bodys (such as refuse dump, spoil area, loose rock dam etc.) particularly, because the size of its bulk material differs greatly, little can micron order, and large can reaching more than 1.0 m, in the loose soil body of particle diameter great disparity like this, carry out engineering investigation, significantly collapse hole and (returning without the flushing liquor) phenomenon of leaking can appear, thereby affect normally carrying out of survey, so need in the prospecting process, in time whitewash a large amount of spaces in supporting hole wall and the shutoff gravelly soil, only in this way just can drill normally work.But current to collapse hole and main the employing or artificial slip casting or change special grouting equipment and carry out slip casting of leaking in the loose soil body prospecting, thus reach the purpose in slip casting retaining wall and shutoff borehole wall space, but when so not only useless, but also consumptive material, its effect is not remarkable yet.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, practical boring slip casting retaining wall drilling rig, when useless when solving slip casting retaining wall and shutoff borehole wall space, the problem of consumptive material.
The utility model is realized by following technical scheme: a kind of boring slip casting retaining wall drilling rig comprises mud pit 1, defeated slurry flexible pipe 2, slush pump 3, capstan device 5, drilling tool 7; Defeated slurry flexible pipe 2 one ends are connected with mud pit 1, and the other end is installed on the capstan device 5 by slush pump 3, and capstan device 5 is installed in drilling tool 7 upper ends, and drilling tool 7 tops are equipped with drilling rod interface 4.
Described capstan device 5 inside are installed on ball 10, rotary connector 13, rotary connector 13 is that ball 10 and capstan device 5 are coupled together, its role is to make capstan device 5 revolution and rotation with drilling tool 7 under the drive of ball 10, offer spillage mouth 12 on the rotary connector 13, its role is in the defeated slurry of the cement grout input passage 9, can prevent that defeated slurry flexible pipe 2 is wrapped on the drilling tool 7, can be transported to cement grout again in the defeated slurry passage 9 thereby reach.
Be provided with water transport channel 11 in the described drilling tool 7, the middle part is provided with defeated slurry passage 9, drilling tool 7 outsides offer the vane 6 of sped structure, drilling tool 7 outsides also are equipped with refractory gunning equipment 8, vane 6 can guarantee that boring is not eccentric in the drilling process, and make the disintegrating slag that produces in the boring under the effect of flushing liquor (water), take ground to along the spiral groove of drilling tool 7, guarantee that simultaneously refractory gunning equipment 8 and hole wall have certain distance (namely guaranteeing the effect of setting and the whitewashing of refractory gunning equipment 8).
The input of described refractory gunning equipment 8 offers mouth spray 14, and refractory gunning equipment 8 has blowing mouth 16 and valve pearl 15 is installed with drilling tool 7 junctions.Described refractory gunning equipment 8 be placed in the structure groove of vane 6 and with level at an angle, purpose be can make valve pearl 15 by self gravitation with 16 shutoff of blowing mouth, and can guarantee that again valve pearl 15 can open under the impact of pressure slurries.The diameter of described mouth spray 14 is less than the diameter of valve pearl 15, and purpose is to prevent that valve pearl 15 is rushed out outside the refractory gunning equipment 8.Described valve pearl 15 coincide with blowing mouth 16 sizes, and effect is that valve pearl 15 can be washed open by slurries automatically when whitewashing, and valve pearl 15 can fall and block blowing mouth 16 by deadweight when not whitewashing, thereby prevents that borings from entering in the defeated slurry passage 9 of drilling tool 7.
The utility model compared with prior art has following beneficial effect:
1, can reach the effect of drilling tool, also when creeping into, can finish the function of whitewashing retaining wall;
2, the rotation with drilling tool when impact rotating creeps into of defeated slurry flexible pipe is rotated;
3, when whitewashing, the pressure energy of cement grout is washed the valve pearl open, reaches the order of whitewashing;
4, refractory gunning equipment has certain inclination angle, and the valve pearl can rely on gravity autoshutdown blowing mouth, thereby prevents that borings from entering the defeated slurry passage of drilling tool;
5, the design of vane structure can make under the uninfluenced prerequisite of boring, guarantees the smooth discharge of gunite effect and borings;
6, effective than other slip casting retaining wall of whitewashing retaining wall, and can greatly reduce the consumption of cement;
7, need not change drilling tool and miscellaneous equipment during retaining wall, can greatly improve its efficient, save the plenty of time;
8, vane, refractory gunning equipment and capstan apparatus structure are simple, design ingenious, practical.
