Abstract
Disclosed is a deformation-resistant transmission tower, which is particularly applied to the high-voltage transmission iron towers of the high-voltage transmission lines in subsidence areas; a deformation-resistant mat foundation is arranged under the iron towers, with a foundation short column corresponding to the support leg of the iron tower arranged thereon; a self-adapting deformation connected node of the support leg of the iron tower is fixed on the foundation short column; and a sand cushion is arranged at the downside of the deformation-resistant mat foundation. The connection way of a high strength bolt is fully used; certain member flex space is released for the iron tower to adapt to foundation deformation; the stress generated by iron tower members is actively lowered after the surface of the subsidence area is deformed; and such brittle fracture as node tearing is avoided in some way. The utility model is characterized by simple construction, good result and wide practicability.
Description
Technical field
The utility model relates to the transmission tower of ultra-high-tension power transmission line, especially a kind of resistance to deformation transmission tower that is applicable to mine worked-out section.
Technical background
Coal is the main energy sources of China, and in the primary energy consumption of China, coal accounts for about 70%.Because coal is after underground extraction, its top covering layer loses support, causes that the above goaf face of land produces mobile and distortion.Move and the distortion on the face of land directly have influence on the basis of building, thereby cause building to destroy.
In recent years,, badly influence the safety of overhead transmission line line pole tower, caused very big threat and harm for the ultra-high-tension power transmission line, the iron tower that pass through or be seated on the minery along with the expansion of underground mining scope; On the other hand, along with the construction of near coal-mine power plant and the continuous development of electrical network in recent years, increasing transmission line of electricity need pass through minery.Only adopt the mining measure that reduces surface deformable to be difficult to guarantee the safety of ground transmission tower at present, because the fundamental realities of the country that China has a large population and a few land, many mining areas are exactly mining collapse area except that basic farmland.Therefore building transmission line of electricity at mining collapse area has become certainty, and exploitation minery resistance to deformation iron tower has become current urgency problem to be solved.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of simple in structure, and it is strong initiatively to adapt to deformability, effective, the resistance to deformation transmission tower that cost is low.
For achieving the above object, the technical solution of the utility model is, have the resistance to deformation mat foundation at the iron tower pylon, the resistance to deformation mat foundation is provided with and the corresponding basic short column of iron tower pylon leg, be fixed with on the short column of basis and iron tower pylon leg self adaptation distortion connected node, resistance to deformation mat foundation bottom is provided with sand cushion.
Described self adaptation distortion connected node is by a seat board that is fixed on the basic short column, is fastened on the iron tower rod member on the seat board and the stone bolt formation of fixed anchor plate with the high-strength bolt double shear; Described double shear connects and comprises backing plate and the junction plate that is fixed on the seat board; Described iron tower rod member is provided with the bar shaped connecting hole, is provided with slide block in the bar hole.
The beneficial effects of the utility model: the iron tower rod member produces big stress after adapting to the subsidence area surface deformable taking place, and brittle fracture such as avoids taking place that node is torn, and also is applicable to the reinforcing of the original electric power pylon of above goaf.Can effectively increase the integral rigidity and the intensity of tower foundation, the subsidiary stress that sedimentation, inclination, curvature and the horizontal distortion on the opposing minery face of land produces on transmission tower, and the influence that can stand to adopt, guarantee the safety of transmission tower, its construction is simple, effective, have practicality widely.
