Abstract
The utility model provides a composite plate foundation for a transmission tower in a coal mine subsidence area. An independent foundation for flexible concrete is arranged below a support leg of an iron tower frame and is arranged on the concrete composite plate; a sliding layer is arranged between the concrete composite plate and the independent foundation for flexible concrete; and a sand cushion laid according to the design height is arranged at the lower part of the concrete composite plate. The structure enhances the integrity of a tower foundation effectively, can decrease additional stress applied on the transmission tower due to vertical deformation and horizontal deformation of a ground surface remarkably, thereby enabling the composite plate foundation to be capable of undergoing the mining influence, ensuring the safety of the transmission tower, and being convenient for the independent foundation for flexible concrete to recover in place. The utility model is most suitable for protecting a new transmission tower in a subsidence area, and has the advantages of simple construction, good effect, and wide practicability.
Description
Technical field
The utility model relates to a kind of transmission tower composite plate basis, the transmission tower composite plate basis of subsidence area, especially a kind of colliery ultra-high-tension power transmission line.
Background technology
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, 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.On the other hand,, badly influence the safety of existing high-voltage transmission line pole tower, ultra-high-tension power transmission line on subsidence area (minery) and pylon have been caused very big threat and harm along with the expansion of underground mining scope.Therefore, carry out the research on minery resistance to deformation power transmission tower frame and basis, the safety of guaranteeing high-voltage transmission line pole tower is had great importance.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the prior art, provides a kind of non-deformability strong, and construction is simple, the transmission tower composite plate basis, subsidence area, colliery that cost is low.
For achieving the above object, transmission tower composite plate basis, subsidence area, colliery of the present utility model, leg at the iron tower pylon has the flexible concrete single footing, the flexible concrete single footing is located on the concrete slab, be provided with sliding layer between concrete slab and the flexible single footing, the concrete slab bottom is provided with the sand cushion by the design height place mat.
Described sliding layer by the layers of asphalt malthoid of therebetween graphite powder or mica sheet or layer of sand and on the layers of asphalt malthoid form; Described composite plate is made by steel concrete; The thickness of described sand cushion is greater than 300mm.
The beneficial effects of the utility model: this structure has increased the globality of tower foundation effectively, can significantly reduce the subsidiary stress that vertical surface deformation and horizontal distortion produce on transmission tower, the influence that makes it stand to adopt, guarantee the safety of transmission tower, the answer of being convenient to flexible single footing simultaneously is in place, is particularly useful for the high voltage power transmission iron tower of subsidence area ultra-high-tension power transmission line.It is simple in structure, and non-deformability is strong, and construction is simple, and cost is low.
Description of drawings
Accompanying drawing is subsidence area, colliery of the present utility model transmission tower composite plate foundation structure figure.
Among the figure: 1. iron tower pylon, 2. flexible concrete single footing, 3. sliding layer, 4. concrete slab, 5. sand cushion.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Transmission tower composite plate basis, subsidence area, colliery of the present utility model is made up of iron tower pylon 1, flexible single footing 2, sliding layer 3, concrete slab 4, sand cushion 5.Flexible concrete single footing 2 is set under the leg of iron tower pylon 1, flexible concrete single footing 2 is located on the concrete slab 4, between concrete slab 4 and the flexible single footing 2 sliding layer 3 is set, sliding layer 3 by the layers of asphalt malthoid of therebetween graphite powder or mica sheet or have certain thickness layer of sand and on the layers of asphalt malthoid form.Design height place mat sand cushion 5 is pressed in concrete slab 4 bottoms, and composite plate 4 is made by steel concrete; The thickness of sand cushion 5 is greater than 300mm.
The course of work: after at first reaching projected depth according to designing requirement excavation ground, adopt medium sand construction sand cushion 5, compaction in layers reaches design thickness, again construction reinforced bar concrete slab 4, sliding layer 3, flexible single footing 2 successively.After 2 constructions of flexible single footing are finished, iron tower pylon 1 is installed.
