Detailed description of the invention
Below in conjunction with accompanying drawing, further explanation is explained to this patent.But the protection domain of this patent is not limited to concrete embodiment.
Embodiment 1
As shown in the figure, the self-drilling hollow anchor bars filling adaptor of this patent, comprises slip casting sleeve 1, slip casting bar 2, sealing ring 3, lubricating cup 4 and lubricating cup cover 5; Described slip casting sleeve 1 is fixed on rig output, for ensureing that in rotary drilling process, slurries can enter anchor pole cavity; Described slip casting bar 2 in drilling process along with rig output rotates together; Described sealing ring 3 is for preventing the leakage of slurries in rotary drilling process; Described lubricating cup 4 ensures the lubrication between sealing ring 3 and slip casting bar 2.
Slip casting sleeve 1 is a weldment, by sleeve 101, Grouting Pipe joint 102, reinforcing rib 103(2), fixed head 104 is welded; Its middle sleeve 101 two ends orifice diameter 1mm larger than slip casting bar 2 diameter, four seal grooves are left at middle part, for installing sealing ring 3, all the other inside diameters 15mm larger than slip casting bar 2 diameter, sleeve 101 exterior periphery is on 180 ° of directions, the hole that diameter is 40mm is left in middle part on one side, and the lubricating cup hole of symmetrical two M10 of another side, lubricating cup hole lays respectively between two seal grooves.Grouting Pipe joint 102 is welded in sleeve 40mm hole place, and wherein one end is gas thread made in Great Britain, and other end cylindrical is a step, is convenient to the location in welding process; Reinforcing rib 103 is the triangular steel plate that two pieces of 10mm are thick, is welded in the two ends of sleeve 101 and Grouting Pipe interface 102 junction on sleeve 101 length direction; Fixed head 104 is the rectangle steel plate of one piece of thick middle with hole of 20mm, is welded in the middle part of sleeve 101 cylindrical on sleeve 101 length direction, and perpendicular to Grouting Pipe interface 102 position.
Slip casting bar 2 is single-revolution body, two ends internal thread is respectively used to connect rig output and anchor pole, and centre is not communicated with, this slip casting bar 2 cylindrical 30 ~ 40mm larger than maximum thread Pilot hole diameter with slip casting sleeve 1 mating part size, axially middle part 50 ~ 60mm scope inside and outside circle diameter 5 ~ 10mm less of fit diameter, and on circumference 90 ° of directions, have two vertical water holes to lead to slip casting bar 2 core, the bottom of thread water hole that this water hole and anchor pole coordinate communicates, and rig output abutting end length is at 35 ~ 40mm scope inside and outside circle diameter, 15 ~ 20mm larger than fit diameter.
Described sealing ring 3 is arranged in the seal groove in sleeve 101, reveals for preventing slurries.
Described lubricating cup 4 is arranged in lubricating cup hole, and lubricating cup cover 5 is arranged in sleeve 101 outer rim corresponding with lubricating cup hole, and the center line in lubricating cup hole and the center line of lubricating cup cover 5 overlap; Oil is injected by lubricating cup 4, carrys out lubrication and seal circle.
Comparative example 1
Hollow bolt of the prior art is connected directly between on the output of rig by bit shank sleeve, after boring, remove the connection with rig, anchor pole is received slip casting on grouting pump, for the rock of the hollow bolt Drilling 6m of R32, drilling time is 5min, changing-over grouting pump needs 1.5min, grouting pump pressure is 0.8MPa, and slip casting completes needs 4min, whole work progress 10.5min consuming time.If the self-drilling hollow anchor bars filling adaptor using patent of the present invention to mention can be implemented in slip casting simultaneously in the process of rotary drilling, avoid changing-over grouting pump, and for loose, breaking surrounding rock, supporting in advance, avoids collapse hole; In the process of creeping into, drilling cuttings can be gone out outside hole by slurries, thus improves rate of penetration, and the while of hole-drilled, slip casting terminates, and whole work progress is less than 5min.Be equivalent to save half many time.
Visible, the construction method operation of prior art is many, and construction is complicated, and need more manpower, elapsed time is long, and for loose, breaking surrounding rock, pore-forming is more difficult, and easy collapse hole adds the difficulty of construction.And the construction method after increasing can improve the defect of this respect.
