Description
Technical field
The present invention relates to work transmission line field, specifically a kind of flexible roof bolt basis.
Background technology
Foundation engineering is the important component of work transmission line construction, relation whole piece circuit it is safe for operation, once
There are the security incidents such as collapse, come down, extract in some iron tower foundation, and the operation of whole piece circuit will face paralysis.Therefore Stability Analysis of Structures,
The rational foundation pattern of cost is to reducing work transmission line investment, ensureing that the safe operation of circuit all seems most important.Pass
Transmission line tower foundation pattern construction machinery rate of uniting is relatively low, long construction period；Meanwhile with electric power line pole tower technology
Development, traditional infrastructure is to some Novel rod tower formulas（Narrow base tower, multiloop are from vertical rod etc.）Applicability it is poor, easily occur by
The problems such as power is unreasonable, index is bigger than normal.
Based on this, this case application is proposed.
The content of the invention
It is an object of the invention to provide a kind of Novel rod column foot that can adapt to transmission line of electricity overall process mechanized construction
Plinth, optimize basic stress and index, improve safety, quality, efficiency, the benefit of engineering construction.
To achieve the above object, the technical solution adopted by the present invention is：Flexible roof bolt basis, including upper plate, lower plate and
Upper plate and the anchor cable of lower plate are connected, some through holes is offered in the lower plate, anchor pole is equipped with downwards in through hole.The top of anchor pole
Lower plate top surface is arranged in, the bottom of anchor pole is downwardly into and is fixed in horizon d.
The present invention is further arranged to：At the top of the anchor pole some backing plates are cased between lower plate.
The present invention is further arranged to：The lower plate is concrete round platform or concrete raw sheet, upper plate are square or circular
Concrete slab.
The present invention is further arranged to：The upper plate, lower plate center offer the perforate passed through for anchor cable, the anchor cable one
Head is fixed on upper plate center by metal connecting elements, and lower plate center is fixed in other end by metal connecting elements.
The present invention is further arranged to：The metal connecting elements is billet, billet be respectively arranged on upper plate top surface,
The bottom surface of lower plate.
The present invention is further arranged to：The annular baffle opened pit-size with basis and matched is carried below the upper plate.
The present invention is further arranged to：Filled with the backfill soil body between the upper plate, lower plate.
The present invention is further arranged to：The anchor pole is uniform, symmetrical around anchor cable.
The working principle and beneficial effect of the present invention：In the present invention, when upper plate is acted on by uplift force, anchor cable can
Load is timely, is effectively transferred to lower plate, and the load that lower plate is subject to again is transferred to anchor pole, is born by anchor pole most
Uplift load, small part uplift load are born by undisturbed soil and lower plate.Foundation load of the present invention transmits apparent, simple in construction, energy
The stress index on basis is enough effectively improved, makes basis more stable, safe.
Basis of the invention each part --- upper plate, lower plate, metal connecting elements, roof-bolter anchor cable etc. can be prior to factories
It is middle uniformly to manufacture（Upper plate can standardize unified make with lower plate in job site）, transport and construction are greatly facilitated, together
When ensure that construction quality, shorten the construction period., can and both annexation is also suitable for mechanized construction to its simple structure
Improve efficiency of construction.
Also, the present invention can make full use of the original state soil body, foundation anti-pulling high capacity；And spoir amount can be effectively reduced,
Preserve the ecological environment.

Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, tie below
Embodiment is closed, the present invention is expanded on further.
Embodiment 1
As shown in figure 1, flexible roof bolt 105 is basic, including upper plate 100, lower plate 103, anchor cable 102 and anchor pole 105, upper plate 100 are
Square or circular concrete slab, lower plate 103 are concrete round platform or concrete raw sheet.Upper plate 100 be located at the top of lower plate 103 and
Relative with the position of lower plate 103, lower plate 103 is embedded in the top of horizon d 120.The center of lower plate 103 offers what is passed through for anchor cable 102
Perforate, some through holes are offered in the lower plate 103 of perforate, anchor pole 105 is equipped with downwards in through hole.The top of anchor pole 105
The top surface of lower plate 103 is arranged in by some backing plates, the bottom of anchor pole 105 is downwardly into and is fixed in horizon d 120.
Upper plate 100 is located at earth's surface, and its center equally offers the perforate passed through for anchor cable 102, and the position of opening is with
The position of opening of plate 103 is corresponding.One of anchor cable 102 is fixed on the center of upper plate 100 by upper billet 107, and other end leads to
Cross down billet 104 and be fixed on the center of lower plate 103.Upper billet 107 is under the upper and lower billet 104 of the top surface of upper plate 100 is located at
The lower section of plate 103, so as to play a part of conducting load and fixed anchor cable 102.
The lower section of upper plate 100 carries the annular baffle opened pit-size with basis and matched.Filled between upper plate 100, lower plate 103
There is the body of backfill 110, backfill 110 will be filled up between upper plate 100 and lower plate 103, tamped completely, and anchor cable 102 is also wrapped up,
Reinforce inside it.The both sides of backfill 110 are undisturbed soil 101.When upper plate 100 is acted on by uplift force, the energy of anchor cable 102
Enough loads are timely, are effectively transferred to lower plate 103, and the load that lower plate 103 is subject to again is transferred to anchor pole 105, by anchor pole 105
To bear most uplift load, small part uplift load is born by undisturbed soil 101 and lower plate 103.
In the present embodiment, the quantity of anchor pole 105 is 2.
Embodiment 2
The present embodiment and the difference of embodiment 1 are：The quantity of anchor pole 105 is 4 or 6.
Based on above-mentioned, the invention provides a kind of basis of flexible roof bolt 105, and it passes through sets anchor pole 105 in lower plate 103
And the insertion of anchor pole 105 is fixed in horizon d 120, the uplift force that the upper plate 100 transmitted by anchor cable 102 is born is further
Horizon d 120 is transferred to, the most of uplift load born using the hard characteristic counteracting upper plate 100 of horizon d 120, is subtracted significantly
Uplift load suffered by small upper plate 100, lower plate 103, the stress index on basis can be effectively improved, make basis more stable, safe.
Its simple structure, suitable for mechanized construction, it is possible to increase efficiency of construction.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only.Institute
Have within the scope of the present invention or be included in the invention in the change being equal in the scope of the present invention.
