Abstract
The utility model discloses an umbellate form rock stock basis for transmission line engineering, it includes the upper portion cushion cap and the basic cushion cap of cylinder type, upper portion cushion cap and basic cushion cap axial lead heavy merge pass rag bolt connect, the centre of a circle O that uses basic cushion cap bottom surface is the centre of a circle, use R evenly to be provided with the perpendicular anchor eye that does not run through as the radius, downside along the symmetrical slope anchor eye that does not run through that equals with perpendicular anchor eye quantity that evenly is equipped with of the axial lead slope of basic cushion cap of basis cushion cap, perpendicular anchor eye and slope anchor eye staggered arrangement, perpendicular anchor eye is fixed with perpendicular stock through the binder, the slope anchor eye is fixed with the slope stock through the binder. Its simple structure, link up compact, can save the cost under the prerequisite of bearing high transmission line voltage and big shaft tower load.
Description
Technical field
This utility model relates to Rock Bolt Foundation, in particular to a kind of umbellate form Rock Bolt Foundation for work transmission line.
Background technology
In power grid construction, foundation engineering investment accounts for about 15% to the 20% of total investment of engineering proportion, and iron tower foundation optimization design, for reducing construction investment, economizes on resources, and reduces earthwork, and protection environment has very important effect.
Line project electric pressure was the highest in the past, and basic load is little, and for mild wind, middle air slaking Rock Region, anchor rod foundation can use single anchor formula or straight anchor formula group's anchor rod foundation.
Along with the development of China's power construction, transmission line of electricity electric pressure is more and more higher, and tower load is increasing, and basic role power strengthens the most therewith.So, conventional straight anchor formula is used to be difficult to meet requirement；According to straight anchor formula group's anchor rod foundation, owing to anchor pole quantity is more, anchor pole is circular layout and causes top dimension of platform excessive, causes the waste of concrete, loses the economic advantages of anchor rod foundation.
Therefore, a kind of for work transmission line can bear high transmission line of electricity voltage and big tower load and good in economic efficiency Rock Bolt Foundation seems the most necessary.
Summary of the invention
The purpose of this utility model seeks to provide a kind of simple in construction, is connected the compact umbellate form Rock Bolt Foundation for work transmission line, and this anchor rod foundation can be cost-effective on the premise of bearing high transmission line of electricity voltage and big tower load.
For achieving the above object, the umbellate form Rock Bolt Foundation for work transmission line designed by this utility model, it includes top cushion cap and the foundation platform of column type, top cushion cap and foundation platform axial line weight merga pass foundation bolt connect, with the center of circle O of foundation platform bottom surface as the center of circle, with R for radius be evenly arranged with not through vertical anchor hole, the downside of foundation platform tilt along the axial line of foundation platform be provided with symmetrically and evenly equal with Vertical Anchor hole number not through inclination anchor hole, vertical anchor hole and inclination anchor hole interlaced arrangement, vertical anchor hole is fixed with normal bolting by binding agent, tilt anchor hole and be fixed with inclination anchor pole by binding agent.The angle of the axial line tilting anchor pole and foundation platform is 15 °～25 °.The distance tilting the center of circle, the bottom surface O on anchor hole and foundation platform is r, and meets r ＜ R.
Yet further, any one inclination anchor hole is the most equal with the distance of the vertical anchor hole being adjacent.
Further, foundation bolt is arranged with the axial line of top cushion cap for the center of circle along an even circumferential；Foundation bolt is provided with eight.
Further, vertical anchor hole is provided with 12；Correspondingly, tilt anchor hole and be also equipped with 12.
Further, a length of 3～7 meters of normal bolting；Tilt a length of the 3～9m of anchor pole.
Advantage of the present utility model is mainly reflected in following several respects:
One, uses anchor pole can bear high transmission line of electricity voltage and big tower load, can effectively control foundation platform deformation and rock deformation；
Its two, use umbellate form Rock Bolt Foundation to be effectively improved existing rockwork anchor rod foundation distribution of force, reduce foundation anchor quantity, reduce foundation platform size, and then reduce basic resource consumption；
Its three, construct feasible, safe and reliable, there is use promotional value.
