The lower ends of the anchor rod bodies (3) are located in anchor rod holes (6) in the base rock, the upper ends of the anchor rod bodies (3) are located in the bearing platform (1) on the upper portion of the foundation, the anchor rod bodies (3) are fixed with adhesive materials (4) in the anchor rod holes (6), the anchor rod holes (6) are arranged at intervals to form a ring shape, and the pressure grouting hole (2) is arranged at the center of the ring shape formed by the anchor rod holes (6). Compared with straight anchor foundations, the +/-800 kV direct current ring-shaped arrangement rock anchor rod foundation has the advantages that bearing capacity of the whole foundation is effectively improved and application ranges of anchor rod foundations are broadened; and compared with rock built-in foundations, the +/-800 kV direct current ring-shaped arrangement rock anchor rod foundation has the advantages that material consumption and construction excavated volumes are substantially saved.
Description
Technical field
The utility model relates to high-tension transmission line column foot plinth field, and more particularly it is a kind of ± 800kV direct current Rock Bolt Foundation that is circular layout.
Background technology
The under ground portion of electric power line pole tower totally be referred to as the basis.Its effect is the shaft tower that is used for supporting transmission line of electricity.Basic is of a great variety, and what rock foundation often used in the mountain area has Rock Embed based basic with straight anchor formula anchor pole.Wherein, the primary features on straight anchor formula anchor pole basis is: the iron tower stone bolt directly with basement rock through concrete or mortar bonding, the bonding of dependence anchor pole and basement rock and the shearing-resistance characteristic of original basement rock resist tower leg on pull out load.
The inventor is through discovering the pole and tower foundation active force of existing extra-high voltage direct-current circuit; Because the general DC line shaft tower of basic role power is a lot of greatly; Traditional straight anchor formula Rock Bolt Foundation bearing capacity is limited, is difficult to satisfy the requirement of extra-high voltage direct-current shaft tower.With this understanding, need to adopt the artificial Rock Embed based of drawing the excavation formula.The engineering quantity of concrete, reinforcing bar and pit earthwork that this Rock Embed based of drawing the excavation formula is required is bigger.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned existing disadvantages of background technology part, and a kind of ± 800kV direct current Rock Bolt Foundation that is circular layout is provided.Compare the engineering quantity that can reduce concrete, reinforcing bar and pit earthwork with Rock Embed based.
To achieve these goals; The utility model adopts following technical scheme: ± 800kV direct current the Rock Bolt Foundation that is circular layout; It is characterized in that it comprise top cushion cap, be positioned at the slip casing by pressure hole and the anchor rod body of basement rock; The lower end of described anchor rod body is positioned at the bolthole of basement rock, and in the superposed cushion cap in the upper end of anchor rod body, the adhesives in described anchor rod body and the bolthole is fixed together; Described bolthole is the interval and is circular layout, and at the center of bolthole the slip casing by pressure hole is arranged.
In technique scheme, the cushion cap on said top is circle or square structure in the horizontal direction.
In technique scheme, described adhesives is concrete or mortar.
In technique scheme, it also comprises stirrup, and described stirrup is connected and fixed the anchor rod body in the superposed cushion cap, and described stirrup is that sandwich construction is arranged.
In technique scheme, said anchor rod body horizontal section direction is structural configuration ringwise, and said anchor rod body is a screw-thread steel.
This novel embodiment provides ± the 800kV direct current Rock Bolt Foundation that is circular layout mainly comprises: the coefficient steel concrete cushion cap in anchor pole, top through concrete or mortar bonding and basement rock bottom bonding and adopt high pressure grouting after the slit basement rock that obtains filling.
The utility model has effectively improved the bearing capacity on straight anchor formula anchor pole basis; Through changing the arrangement of anchor pole; Increase means such as top concrete bearing platform and high pressure grouting, proposed a kind of novel assembled bolt basis pattern, effectively raised the anchor pole bearing capacity.

The specific embodiment
Below in conjunction with the example case of accompanying drawing detailed description the utility model, but they do not constitute the qualification to the utility model, only do for example.Advantage through explanation the utility model will become clear more and understanding easily simultaneously.
Consulting accompanying drawing can know: the utility model ± 800kV direct current Rock Bolt Foundation that is circular layout; It is characterized in that it comprises cushion cap 1, slip casing by pressure hole 2, the anchor rod body 3 on top; The lower end of described anchor rod body 3 is positioned at bolthole 6; In the superposed cushion cap 1 in the upper end of anchor rod body 3; Described anchor rod body 3 is fixed together with bolthole 6 interior adhesivess 4, and described bolthole 6 is the interval and is circular layout, and slip casing by pressure hole 2 (like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4) is arranged at the center of bolthole 6.
The cushion cap 1 on top is circle or square structure (like Fig. 2, shown in Figure 4) in the horizontal direction.Adhesives 4 is concrete or mortar.It also comprises stirrup 5, and described stirrup 5 is connected and fixed the anchor rod body 3 in the superposed cushion cap 1, and described stirrup 5 is arranged (as shown in Figure 1) for sandwich construction.
The be circular layout work progress of Rock Bolt Foundation of the utility model ± 800kV direct current is following:
Through drilling construction, the bolthole 6 that in basement rock, forms, anchor rod body 3 is placed wherein, and under-filled binding material 4 (concrete or mortar or other materials) is connected as a single entity with basement rock.
The computational methods of basement rock performance improvement are that the obligee passes through test and research obtains after slip casing by pressure hole 2 settings of base center, the mode that is circular layout of bolthole and the high pressure grouting.
Cross section shown in Figure 2 can be circular or square, is to calculate according to concrete foundation condition to confirm.
The employing of above-mentioned arrangement and high pressure grouting technology, upper reinforcement concrete bearing platform 1, anchor rod body 3 and improve the back basement rock and the finally form ± 800kV direct current Rock Bolt Foundation that is circular layout.Compare with straight anchor foundation, effectively improve the bearing capacity on whole basis, enlarged the range of application on anchor pole class basis, compare with Rock Embed based, significantly economical with materials consumption and construction and excavation amount.
