Abstract
The invention discloses a flange type polygonal steel tube foundation. The flange type polygonal steel tube foundation is characterized in that a flat-face flange is welded to the upper end of a polygonal steel tube; a plurality of bolt holes are evenly formed in the flat-face flange; a plurality of stiffening plates are evenly distributed on the periphery of the connecting position of the polygonal steel tube and the flat-face flange in a welded mode; positioning plates are symmetrically arranged on the outer wall of the upper portion and the outer wall of the lower portion of the polygonal steel tube respectively. According to the arrangement, the flange type polygonal steel tube foundation is simple in structure, rapid and convenient to machine, capable of being driven into the ground through construction methods such as striking or vibration or rotation pressing, and capable of meeting the application requirement of steel tube pole foundations of power transmission line projects. The flange type polygonal steel tube foundation is capable of being constructed rapidly, reducing the cover area, shortening the blackout time, and greatly improving the construction efficiency.
Description
Technical field
The present invention relates to power system overhead transmission field, is a kind of steel pipe pole flange form polygonal steel pipe basis specifically.
Background technology
At present, the steel pipe pole base form adopted in electric power overhead power transmission engineering mostly is reinforced concrete foundation, foundation construction area must possess the condition of sand, stone, water, limit by geographical position, need dig on a wide area construction area area large, there is potential safety hazard in excavation foundation hole, needs special messenger to nurse and establish warning mark, and after basis completes, circuit changes path and change steel pipe pole bar position quite difficult.
Summary of the invention
Object of the present invention be just to provide a kind of construct convenient, do not need maintenance, basis lay can directly vertical rod and do not affect engineering use flange form polygonal steel pipe basis.
To achieve these goals, the present invention is welded with face-flange in the upper end of polygonal steel pipe, multiple bolt hole is laid with at described face-flange, be welded with polylith stiffener the junction surrounding of described polygonal steel pipe and face-flange is uniform, the upper and lower outer wall of polygonal steel pipe is arranged with position plate respectively.
By above setting, structure of the present invention is simple, and processing is quick, and squeezes into ground by impacting, vibrating or rotate the construction methods such as press-in, can meet KV Electric Transmissions steel pipe pole base application.The present invention realizes rapid construction, reduces floor space and shorten power off time, greatly improves efficiency of construction.

Fig. 2 is the upward view of Fig. 1.
In figure: 1, polygonal steel pipe, 2, face-flange, 3, bolt hole, 4, stiffener, 5, position plate.
Detailed description of the invention
As shown in Figure 1, 2, the present invention is welded with face-flange 2 in the upper end of polygonal steel pipe 1, multiple bolt hole 3 is laid with at described face-flange 2, be welded with polylith stiffener 4 at described polygonal steel pipe 1 with the junction surrounding of face-flange 2 is uniform, the upper and lower outer wall of polygonal steel pipe 1 is arranged with position plate 5 respectively.By above setting, polygonal steel pipe 1 of the present invention is squeezed into ground by construction methods such as impact, vibration or rotation press-ins, the upper plane of face-flange 2 is flushed with ground, positioned by position plate 5, face-flange 2 is bolted with the steel pipe pole flange in the bottom of power transmission sequence, realizes the effect on the steel pipe pole basis of power transmission sequence.
