Abstract
The utility model relates to the preload stress anchor rope separation construction technology, in particular relates to a rigging drill-bit and stranded wire bunch device that is applicable to different geographic conditions and is used for the built-in stranded wire, which comprises a hollow rod, and the hollow rod is fixed to an appropriate position inside the drill bit; a blocking ring is fixed inside the hollow rod. The device comprises a stranded wire; one horizontal surface of a bunching disc is provided with a plurality of stranded wires, and the horizontal plane at one end of the bunch disc is also provided with a guiding reinforced bar that is fixedly connected with the horizontal plane in inclining way. The device can guarantee that the stranded wire can be correctly arranged at a designed depth, so that the length of the free section and the anchoring section of the anchoring rope can be precisely controlled. The tensile resistance of the anchoring rope can be improved, and the labor intensity of the workers can be reduced; moreover, the structure is simple and reasonable, and the price is low, thereby being greatly convenient for the constructors to use, and effectively improving the construction efficiency.
Description
Technical field
The utility model relates to the construction technology that a kind of prestress anchorage cable send separation, relates in particular to a kind of rigging drill bit that is used for steel strand built-in and steel strand beaming device that is applicable to various geological conditionss.
Background technology
Prestress anchorage cable has been widely applied to deep foundation pit support, the domatic reinforcing of massif, tunnel support etc. in recent years, because its anchorage depth is long, anchoring is reliable and stable, easy construction, accommodation are extensive, are one of best approaches in the present stage anchoring construction.But, along with the scope of application of prestress anchorage cable constantly enlarges and various complex geological conditions, a series of problem has appearred in construction, and the follow-up formula steel strand process of using for traditional secondary grouting technology and present stage all is insurmountable.Particularly can't effectively creep at closely knit boulder bed, pore-forming efficiency hangs down the operating expenses height, the follow-up formula creep into very easily cause steel strand twine, damaged and come off, cause secondary to creep into again, particularly many steel strand can't be constructed, many steel strand can't be concentrated bunchy on same axis, reduce operating efficiency.And free section and anchoring section are uncontrollable, do not have free section substantially, bring very big difficulty to work progress for above-mentioned reasons and limit.
The utility model content
The utility model puts forward at the problems referred to above, the purpose of this utility model provides a kind of device of steel strand built-in, it is simple in structure, easy to use, reach many steel strand and on same axis, concentrate bunchy, and quality is higher, with its send into projected depth accurately, put just, improve efficiency of construction.
The technical scheme of the utility model technical solution problem is for achieving the above object: be used for the rigging drill bit device of steel strand built-in, comprise hollow stem, it is that described hollow stem is fixed at adapting position in the drill bit; Be fixed with snap ring in the described hollow stem.
Described drill bit front portion is provided with a brake pad at least.
Described snap ring one end week upwards is provided with company's piece that matches with drilling rod at least.
Described even piece is any one in boss or the groove.
Be used for the steel strand beaming device of steel strand built-in, comprise steel strand, it is that boundling dish one end horizontal plane is provided with some described steel strand, also is provided with its horizontal plane on the described boundling dish one end horizontal plane to be skewed guiding reinforcing bar of fixedlying connected.
Described steel strand vertically are fixed on the boundling dish horizontal plane.
The utility model compared with prior art has following advantage and effect:
The utility model is fit to put into steel strand under the various geological conditionss, the utility model since adopted broadcast rigging drill bit device earlier and reach projected depth after, put into the steel strand boundling of sending in advance again, no matter be one or many and can both guarantee that steel strand accurately put into projected depth, effectively avoid prior art the problem that comes off and cause secondary to creep into very easily to occur.Also solved in the prior art many steel strand in addition and can not carry out the follow-up formula and creep into, steel strand easily twine a damaged difficult problem.Simultaneously, reached many steel strand and concentrate bunchy on same axis, made that the length of free section of anchor cable and anchoring section is precisely controlled, thereby improved the anchor cable stretching resistance, the work that has alleviated the workman is emphasized, improves efficiency of construction.The utility model is simple and reasonable for structure, safe and reliable, and cost is low, convenient construction person to a greater extent, and under rugged environment, also can normally finish construction working.
Description of drawings
With reference to accompanying drawing, concrete structure of the present utility model is described in detail as follows:
Fig. 1 is the rigging drill bit apparatus structure schematic diagram of the utility model steel strand built-in.
Fig. 2 is the steel strand beaming device structural representation of the utility model steel strand built-in.
Fig. 3 is the work progress schematic diagram of the utility model steel strand built-in.
Fig. 4 is the construction schematic diagram of the utility model steel strand built-in.
Major part among the figure: drill bit 1, snap ring 2, hollow stem 3 connects piece 4, brake pad 5, steel strand 6, boundling dish 7, guiding reinforcing bar 8.
The specific embodiment
Be the rigging drill bit apparatus structure schematic diagram of steel strand built-in as shown in Figure 1, this device comprises hollow stem 3, and it is that described hollow stem 3 is welded on drill bit 1 and is fit in the depth of operation; This drill bit 1 front portion is provided with six brake pads 5 in order to reach better fixation, described hollow stem 3 Inner Front Ends are welded with snap ring 2, upwards being arranged with two even pieces 4 in 2 one end weeks of snap ring, is groove or boss on the borer drill rod, and then associated even piece 4 is boss or groove.
Be the steel strand beaming device structural representation of steel strand built-in as shown in Figure 2, this device comprises steel strand 6, it is five described steel strand 6 of the vertical welding of boundling dish 7 one end horizontal planes, described boundling dish 7 one end horizontal planes also are provided with its horizontal plane and are skewed, and between the two angle less than the guiding reinforcing bar 8 of 90 ° of welding.
Concrete use process of the present utility model is as follows:
Shown in Fig. 3,4 work progress, the end schematic diagram of the utility model steel strand built-in, earlier with boss on the snap ring 2 in the rigging drill bit device and the groove fit on the borer drill rod; If on the borer drill rod be boss, company's piece 4 on the snap ring 2 that then is mated just is groove, drive whole rigging drill bit rotation and pierce in the rock-soil layer of projected depth by rig rotation, then the boss of the drilling rod of rig and snap ring 2 or groove are thrown off and regain, again the steel strand beaming device is manually sent in rigging drill bit hollow core bar 3, the angle adjustment of sending into the reinforcing bar 8 that will lead earlier before the steel strand beaming device is to guiding reinforcing bar 8 can be touched on hollow stem 3 inwalls all the time, after the boundling dish 7 of steel strand beaming device enters snap ring 2, under the ejection of guiding reinforcing bar 8, make boundling dish 7 one ends be stuck on snap ring 2 sides and be fixed.Promptly reach the purpose of smooth steel strand built-in in the rock-soil layer of projected depth.
