Abstract
The utility model discloses an electric transmission line angle steel tower single column high platform bearing type base comprises a high platform, a single column, a lower portion base bearing platform and a climbing ladder. Angle steel tower column pre-embedded parts are arranged on the high platform, the number of the angle steel tower column pre-embedded parts is identical with the number of angle steel tower column feet, and the positions of the angle steel tower column pre-embedded parts correspond to the angle steel tower column feet. The upper end and the lower end of the single column are respectively in rigid connection with the high platform and the lower portion base bearing platform. The climbing ladder is installed on the lateral side of the single column, and the top of the climbing ladder extends to the upper surface of the high platform. When the electric transmission line angle steel tower single column high platform bearing type base is used, reinforcement of all components and burial depth of the lower portion base bearing platform and the single column can be confirmed according to actual situation. Corrosion situation of the root of an angle steel tower can be effectively avoided, occupancy space of the overhead transmission lines on the ground can be reduced, the problem that an angle steel four-foot base cannot be placed due to place limit is solved, and production, life and traffic of surrounding environment cannot be interfered.
Description
Technical field
The utility model relates to overhead transmission line angle-steel tower foundation technical field, especially is applicable to the high platform supports formula of the only post of the angle steel tower of power transmission line basis when the hypothesis transmission line of electricity of area that corrosive ground, river shoal or place scope are restricted.
Background technology
The basic pattern of overhead transmission line angle steel tower adopts cast-in-situ steel reinforced concrete single footing or pile foundation usually.When the geological conditions under the angle steel tower is better, can adopt the cast-in-situ steel reinforced concrete single footing.If can't avoid the disadvantageous location of some geological conditionss in the engineering selected routes stage, angle-steel tower foundation can be designed to pile foundation according to actual conditions.
Generally at below ground or place, ground, four suspension columns of angle steel tower are by directly being bearing on the foundation platform end face with being connected of basic built-in fitting for known angle steel tower single footing or pile foundation, its foundation platform end face.And when the Practical Project route selection, angle steel tower often inevitably can be seated on corrosive ground or the river shoal, because the steel tower root is positioned at underground or too just is easy to be corroded near ground.In addition, when angle steel tower position during near speedway or viaduct next door, because the four limbs suspension column of angle steel tower occupation of land scope is larger, directly be subject to the restriction of speedway or viaduct operation, can't be implemented, adopt steel pipe tower then may face the situation of design span deficiency, therefore can only detour, to avoid unfavorable location.The general meeting of this way also can bring many adverse effects to production and life so that investment increase, the construction period of transmission line of electricity are elongated.
Summary of the invention
The problem that the utility model exists for prior art proposes the high platform supports formula of the only post of a kind of angle steel tower of power transmission line basis, and its underpart occupation of land scope is less, and the situation that can avoid the angle steel tower root to be corroded.
For achieving the above object, the technical scheme that the utility model is taked is: the high platform supports formula of the only post of a kind of angle steel tower of power transmission line basis, and it comprises high platform, insulated column, bottom foundation platform and cat ladder; High platform is provided with the angle steel tower suspension column built-in fitting that quantity is identical with angle steel tower suspension column quantity, the position is corresponding with angle steel tower suspension column distribution form; The up and down two ends of insulated column be rigidly connected respectively high platform and bottom foundation platform; Cat ladder is installed on the sidepiece of insulated column, and the cat ladder top passes to high platform upper surface.
More firm for making behind the embedded depth of foundation of the present utility model, the utility model also comprises the bed course that is built up by plain concrete, and bed course is positioned at the below of bottom foundation platform.
In the utility model, insulated column and high platform and bottom foundation platform are for being rigidly connected, and in order to guarantee to connect reliably, the radial section of insulated column is designed to circle.
But when cable need to be when angle steel tower be in built on stilts wiring and underground distribution and changes mutually, the radial section of the insulated column in the utility model then is designed to annular, and the bottom of insulated column is provided with the cable through hole.Concrete, the cable through hole is 2, the axial one-tenth 90 degree angles of 2 through holes, along the radially setting of insulated column.
In the utility model, high platform form of structure can be beam type or the beam slab lid formula of encorbelmenting, wherein encorbelment beam type namely, high platform is comprised of 4 semi girders along the uniform setting of insulated column periphery, an end of each semi girder is fixed on the insulated column, the other end is unsettled; The quantity of angle steel tower suspension column built-in fitting is 4, is arranged at respectively on 4 semi girders.
The high platform structure of beam slab lid formula namely, high platform is by 4 semi girders along the uniform setting of insulated column periphery, and the landing slab that is covered in 4 semi girders tops forms; Angle steel tower suspension column built-in fitting is arranged on the landing slab; The position corresponding with cat ladder is provided with the operation hole that can supply the people to pass through on the landing slab.
The utility model is when using, can determine the arrangement of reinforcement of each ingredient and the buried depth of bottom foundation platform and insulated column according to actual conditions: mainly directly transmit the load that comes according to the angle steel tower suspension column such as high terrace part and carry out combination of internal forces and arrangement of reinforcement calculating, insulated column mainly carries out combination of internal forces and arrangement of reinforcement calculating according to the end reaction of angle steel tower suspension column and the deadweight of high platform, and bottom all upper loads of foundation platform Main Basis and earthing weight are determined key dimension, buried depth and arrangement of reinforcement.The load situation that the bottom foundation platform transmits according to geological conditions and top can be designed to single footing or pile foundation, with traditional foundation class seemingly.Four suspension columns in the bottom of overhead transmission line angle steel tower are located on the high platform, are connected with angle steel tower suspension column built-in fitting on the high platform, form hinged column base, and this moment, end reaction only had vertical force and horizontal force, and did not have moment of flexure.
The beneficial effects of the utility model are: so that the angle steel tower suspension column drops on the high platform that certain altitude is overhead arranged, the situation of effectively having avoided the angle steel tower root to be corroded, also reduced the occupation of land space of overhead transmission line at the place, ground, solve site condition and be restricted and can not have satisfied the contradiction on placement angle steel tower four pin bases, thereby do not hindered production, life and the traffic circulation of surrounding environment.Because high platform has certain height, when satisfying the design span, also reduced the making height of angle steel tower in addition; The selection of insulated column can adopt steel concrete to replace steel work, has reduced overall cost.
