Abstract
The utility model discloses an angle steel tower foundation of an overhead power transmission line. The angle steel tower foundation comprises a planar steel truss, a supporting member and anchor rods. The planar steel truss comprises main beams and subsidiary beams, wherein the main beams and the subsidiary beams are arranged in a net mode, and foundation bolts are arranged at joints between the main beams and the subsidiary beams. One end of the planar steel truss is directly hinged to one anchor rod. The other end of the planar steel truss is directly hinged to the other anchor rod through the supporting member. The overall planar steel truss is on the same horizontal plane. The angle steel tower foundation of the overhead power transmission line has the advantages that the disadvantage that a conventional mountain land foundation is large in floor space is overcome, mountain land earth-rock excavation is greatly reduced through the processing method of zero foundation plane descent, large-area damage to mountain rocks and damage to the integrality and stability of side slopes are avoided, the earth-rock excavation volume is small, construction is convenient, and water and soil conservation and environmental protection are promoted.
Description
technical field
The utility model relates to for electrical domain, particularly a kind of overhead transmission line angle-steel tower foundation.
Background technology
In life, the normal angle steel tower overhead transmission line that adopts carrys out conveying high-pressure electricity, in the time being positioned at mountain area high gradient slope, because physical features height in mountain region rises and falls, the ground height of four tower legs of carrying angle steel tower differs, for making angle steel tower upright, generally can adopt two kinds of patterns of comprehensive height leg angle steel tower or half overhanging type steel truss basis.
Local basement rock soil is that overall rock and the hillside gradient are when steeper, especially the location that is greater than 45 ° in the gradient, adopt half overhanging type steel truss basis can cause large-area earthwork evacuation, constructional difficulties, dangerous high, base values is poor, larger to environmental disruption, what construction produced abandons stone, the difficult processing of spoir, and the high slope of formation easily impacts massif resistance to overturning; In the time adopting the pattern of comprehensive height leg angle steel tower, if the differential maximum considerably beyond steel tower unequal leg of unequal leg is used differential, adopt the method that reduces basal plane or hillside downside pilum is up extended to be difficult to solve, and the measure that basal plane falls in excavation is also unfavorable for stability of slope and environmental protection, and pilum concrete square amount is very large while extending, cost is high, constructional difficulties.
Utility model content
The purpose of this utility model is to solve special high slope, the vertical tower problem in serious limited mountain area, Li Ta position.For addressing the above problem, the technical scheme that the utility model is taked is as follows:
A kind of overhead transmission line angle-steel tower foundation, comprises plane steel truss, supporting member and anchor pole;
Described plane steel truss comprises girder and secondary beam, girder and secondary beam intersect and are netted setting, and the node place of girder and secondary beam is provided with stone bolt, and stone bolt is for established angle head tower, one end of plane steel truss directly and anchor pole hinged, the other end is hinged by supporting member and anchor pole.
Further, described plane steel truss also comprises bridging, and the two ends of bridging are hinged with two diagonal angles of plane steel truss respectively.
Further, girder and secondary beam are i iron or H shaped steel, and support bar is steel pipe or i iron or H shaped steel.
One end of plane steel truss is directly fixed by anchor pole and rock, the other end is fixed with rock by supporting member and anchor pole successively again, make plane steel truss entirety in same level by the length and the direction that change supporting member, thereby angle steel tower is installed on plane steel truss stably, do not need massif to fall base processing, this zero processing mode of falling basal plane greatly reduces mountain soil rock excavation, avoid destroying the destruction of massif rock and the globality to side slope and stability on a large scale, there is earthwork evacuation amount little, easy construction, be conducive to water and soil conservation, the advantages such as environmental protection.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the utility model plane steel truss composition schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As depicted in figs. 1 and 2, a kind of overhead transmission line angle-steel tower foundation of the utility model, comprises plane steel truss 1, supporting member 2 and anchor pole 3;
Described plane steel truss 1 comprises girder 4 and secondary beam 5, girder 4 and secondary beam 5 intersect and are netted setting, the node place of girder 4 and secondary beam 5 is provided with stone bolt, one end of plane steel truss 1 directly and anchor pole 3 hinged, the other end is hinged by supporting member 2 and anchor pole 3, is horizontally disposed with by regulating the length of supporting member 2 and angle that plane steel truss 1 is.Four suspension columns of angle steel tower 8 are connected with the stone bolt on plane steel truss 1, and the planar dimension of plane steel truss is opened size design according to 8 of angle steel towers.
Steel truss girder 4 and secondary beam 5 adopt H shaped steel or i iron, and supporting member 2 adopts steel pipe, i iron or H shaped steel, and bridging 6 adopts steel pipe.
Specific implementation process of the present utility model is: 8 four suspension columns of angle steel tower of overhead transmission line drop on plane steel truss 1, be connected to form hinged column base by stone bolt and girder 4, suspension column horizontal reacting force and vertical counter-force pass to anchor pole 3 by plane steel truss 1 and supporting member 2, then pass to ground by anchor pole 3 and bear.
It is better that a kind of overhead transmission line angle-steel tower foundation of the utility model has mainly solved rock overall performance, the vertical tower problem in high gradient slope district that grade of side slope is larger, solve the comprehensive height leg of angle steel tower and coordinated the still vertical tower difficult problem of the high drop physical features in very scabrous mountain region of height basis, overcome the large inferior position of conventional mountain region basis floor space, greatly reduce mountain soil rock excavation by zero processing mode of falling basal plane, avoid destroying the destruction of massif rock and the globality to side slope and stability on a large scale, there is earthwork evacuation amount little, easy construction, be conducive to water and soil conservation, the advantages such as environmental protection.
