The specific embodiment
Below in conjunction with drawings and Examples the utility model is done and to be described in further detail:
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 and Fig. 9 illustrate the structure of improved grouting cable anchor of the present utility model.Improved grouting cable anchor is made up of cable body 1, stop grouting plug 2, supporting plate 3 (also claiming pallet, anchor dish, anchor slab) and ground tackle 4.Cable body 1 is made up of hollow steel twisted wire section 13, round steel cable core 9, steel pipe cable core 10, slip casting interface 11, metal pipe collar 15 etc.Hollow steel twisted wire section 13 is sections from 12 interceptings of hollow steel twisted wire.
The manufacturing process of the cable body 1 of improved grouting cable anchor at first is the hollow steel twisted wire section 13 that needs length from 12 interceptings of hollow steel twisted wire; Be that an end of hollow steel twisted wire section 13 is removed twisting then, each the bar line limit silk 18 that separates hollow steel twisted wire section 13, expose hollow core 14, clip the part of hollow core 14 ends according to the length requirement of round steel cable core 9, and on hollow core 14 remaining parts, process auxiliary grout outlet 17, subsequently the end of the end of round steel cable core 9 and hollow core 14 remaining parts is aligned the centre twisting again of putting into each the bar line limit silk 18 that separates, again to make according to the size requirements of main grout outlet 16 during twisting and leave between the end of the end of round steel cable core 9 and hollow core 14 remaining parts at interval, be inserted in the anchoring section 5 of the cable body 1 of the metal pipe collar 15 and the improved grouting cable anchor of formation that is fixedly clamped again after the twisting from the end with the grout outlet 16 of deciding; Be that the other end of hollow steel twisted wire section 13 is removed twisting again, each the bar line limit silk 18 that separates hollow steel twisted wire section 13, expose hollow core 14, clip the part of hollow core 14 ends according to the length requirement of steel pipe cable core 10, the centre twisting again that subsequently end of the end of steel pipe cable core 10 and hollow core 14 remaining parts is connected together and put into each the bar line limit silk 18 that separates is sleeved on slip casting interface 11 on the exposed junction of steel pipe cable core 10 and steel pipe cable core 10 after the twisting again, the end of the end of slip casting interface 11 and hollow steel twisted wire section 13 is welded into the connection section 7 of the cable body 1 of integrally formed improved grouting cable anchor; The centre of hollow steel twisted wire section 13 is exactly the grout compartment 6 of the cable body 1 of improved grouting cable anchor for one section.
On the connection section 7 of the cable body 1 of the improved grouting cable anchor that the manufacturing is finished successively cover load onto stop grouting plug 2, supporting plate 3 and ground tackle 4 and just formed improved grouting cable anchor of the present utility model.
The application and construction process of improved grouting cable anchor at first is to hole on coal or rock, the quantity of resin powder stick of packing into after boring is finished; Use the end of the anchoring section 5 of cable body 1 to promote the through foot of hole of resin explosive roll then, when continuing in boring, to advance cable body 1, utilize 1 pair of resin explosive roll of outer six sides rotation cable body of slip casting interface 11 to stir, the resin explosive roll resin that breaks is flowed out, and resin is fully mixed produce and solidify, the anchoring section 5 anchors knot that makes cable body 1 is in the boring of coal or rock; The firm anchors knot of anchoring section 5 for the treatment of cable body 1 in the boring of coal or rock after, overlap successively from the end of the exposed parts 8 of the connection section 7 of cable body 1 and to load onto stop grouting plug 2, supporting plate 3 and ground tackle 4, and the ground tackle 4 that is strained and fixed, promote stop grouting plug 2 and enter the aperture of holing on coal or the rock, supporting plate 3 is pressed on coal or rock face or strengthens finishing the installation process of improved grouting cable anchor on the liner; Improved grouting cable anchor is after installation, by the slip casing by pressure in coal or rock-boring and crack of slip casting interface 11, steel pipe cable core 10, hollow core 14, main grout outlet 16 and auxiliary grout outlet 17, realize the comprehensive anchoring of grouting cable anchor to coal or rock.
This improved grouting cable anchor has been simplified manufacturing process, makes processing and manufacturing more convenient, simple.This improved grouting cable anchor, the stressed uniformity of each bar steel wire can improve supporting capacity effectively, further improves supporting effect, and is more safe and reliable to the supporting in roadway, tunnel.
