Abstract
The utility model relates to a device for anchoring inherent stress anchor lines, which belongs to an inherent stress anchoring device. An anchor plate and a dual-purpose anchoring pipe are in cross under; the outside diameter of the dual-purpose anchoring pipe is smaller than the diameter of the hole arranged on the anchor plate; and one end of two to four pressure-operated rods is fixedly connected with the anchor plate, and the other end is fixedly connected with a support and fixing rod. The utility model has the advantages that the structure is novel; during the anchoring operation, the water can be drained and the anchor lines can be paid off at the same time; the operation is convenient; the operation procedures is reduced; the operation time is shortened; the anchor lines are better combined with the rock surface or the concrete surface; and the strengthening effect is better.
Description
Technical field
The utility model belongs to the prestressed anchor fixing apparatus.
Background technology
Prestressed anchorage technology has had very big development and application widely as the reinforcing means to side slope, country rock, basis and various buildings.The advantage of prestressed anchorage technology is by applying prestressing force, make the rock of resistance to tension weakness or concrete be in pressured state all the time, so structure is in elastic stage all the time, has improved its functional performance, problems such as unlikely appearance cracking, seepage, corrosion.Secondly, prestress anchorage cable both can use separately, made full use of geotechnical body self intensity, thereby saved a large amount of engineering materials, can use with other textural associations again simultaneously, improved its stress, saved a large amount of bricklayings, had distinct economic.During the hydraulic structure reinforcing, adopt prestressing technique, because construction area is little, need not a large amount of excavations or concreting, basically do not influence the operation of existing building thing, and have characteristics such as construction speed is fast, duration weak point, construction safety, this all is its special advantage.Prestressed anchorage technology is increased, is reinforced at dam, and large-scale arc door gate pier is reinforced, the landslide regulation, high gradient slope is reinforced, structure overturning or slip resistance analysis, local strengthening member, deep foundation engineering, aspects such as the maintenance of pressurized tunnel prestressed grouting and various buildings and reinforcement are all used to some extent.
In the construction prestressed cable process,, can influence the effect of the installation and the anchor grouting of anchor cable greatly if in the anchor hole water is arranged.
Summary of the invention
The utility model provides a kind of device of being convenient to the prestress anchorage cable anchoring, to solve in the anchor hole water is arranged, and can influence the installation of anchor cable and the problem of anchor grouting effect greatly.The technical scheme that the utility model is taked is: the dual-purpose pipe cross-under of anchor slab and anchoring, the external diameter of the dual-purpose pipe of this anchoring be less than the aperture on the anchor slab, and 2～4 pressure actuating rod one ends are fixedlyed connected with this anchor slab, the other end is fixedlyed connected with the support fixation bar.
During use, anchor cable and the dual-purpose pipe of anchoring are passed hole on the anchor slab together, anchor cable, anchor slab, pressure actuating rod are put into anchor hole simultaneously, exert pressure ponding is discharged by the dual-purpose pipe of anchoring, if the dilutional hyponatremia in the anchor hole, in the time of can't all discharging by pressure, can draw water from the dual-purpose pipe of anchoring with suction pump, after anchor cable enters the anchor hole assigned address, with the support fixation bar anchor cable and pressure actuating rod are fixed in ground, by the slip casting in the anchor hole of the dual-purpose pipe of anchoring, anchor slab is enclosed in slip casting in the anchor hole again, makes anchoring everything goes well with your work to carry out.
The utility model has the advantages that novel structure, when anchor cable construction, can lay anchor cable in draining limit, limit, not only be convenient to construction, reduced construction sequence simultaneously, shortened the construction period, and make the anchor cable can better be in scar or concrete surface combination, consolidation effect be better.

The specific embodiment
Anchor slab 3 and dual-purpose pipe 4 cross-under of anchoring, the external diameter of the dual-purpose pipe of this anchoring be less than the aperture on the anchor slab, and 2 pressure actuating rod 2 one ends are fixedlyed connected with this anchor slab, the other end is fixedlyed connected with support fixation bar 1.
Anchor slab 3 and dual-purpose pipe 4 cross-under of anchoring, the external diameter of the dual-purpose pipe of this anchoring be less than the aperture on the anchor slab, and 4 pressure actuating rod 2 one ends are fixedlyed connected with this anchor slab, the other end is fixedlyed connected with support fixation bar 1.
Claims (1)
1, a kind of device of being convenient to the prestress anchorage cable anchoring, it is characterized in that: the dual-purpose pipe cross-under of anchor slab and anchoring, the external diameter of the dual-purpose pipe of this anchoring is less than the aperture on the anchor slab, and 2～4 pressure actuating rod one ends are fixedlyed connected with this anchor slab, the other end is fixedlyed connected with the support fixation bar.
