Description
Technical field
The utility model is related to vacuum degreasing apparatus fields, are held more particularly to a kind of transmission line of electricity composite structure assembled
Platform anchor rod foundation.
Background technology
With the high speed development of China's power construction, more and more line corridors need approach high mountain or knob, adopt
With rock-bolt, the damage of hand excavation or bursting work to basic surrounding rock basal plane, tree cover can be significantly reduced, because
And there is preferable economy and environmental benefit.
In the prior art, anchor rod foundation has the following problems：
1. foundation platform part uses cast-in-place concrete, job mix concrete amount is larger, and transmission line foundation is mostly
Locate in high and steep mountains, cast in situs, construction material control, the match ratio metering of concrete, mold assembles control accuracy, and scene is supported
Guard strip part, it is all not ideal enough, cause concrete quality unstable.
2. foundation platform part is unfavorable for carrying out transmission line of electricity mechanized construction, construction site manpower using cast-in-place concrete
It puts into big, safe mass and benefit level of efficiency is relatively low.
In addition, in order to accelerate the duration, construction quality is improved, cast in situs amount is reduced and wet construction, transmission line foundation is normal
Using assembling type base, also known as prefabricated foundation, it is a kind of prefabrication, site-assembled foundation pattern.Using assembled base
Plinth shortens the construction period 1/3~1/2, and the quality of basis processing has than the labour that cast in situ concrete foundation saves 30%~50%
Ensureing (under the processing conditions of factory), construction operation is influenced small by seasonal climate, is conducive to mechanization or semi-mechanization operation,
The job safety for reducing construction personnel meets the developing direction of transmission line foundation construction.
Currently, the assembling type base pattern applied in domestic transmission line of electricity mainly has right cylinder floor type, pyramid support rack type, tower
Several patterns such as leg baried type, metal foundation.The common ground on these bases is with the weight resistance uplift force of soil, that is, gravity
Formula basis is still to use to dig the form of construction work filled out greatly greatly, i.e., usually said heavy excavation mode, but not environmentally friendly enough, especially
For mountain area rock geology, heavy excavation mode not only construct it is especially difficult, since the structural behaviour that could not play rock is fully sharp
With the advantage of undisturbed soil (rock) so that foundation excavation amount is larger, and investment is higher, and spoir problem, soil erosion is also brought to ask
Topic.So it is not extensive for mountain area popularization assembling type base, it mostly uses raw fly ash greatly at present and such as draws digging, pile foundation and rock
Stone anchor rod foundation.
In addition, traditional gravity assembling type base has the following problems
1. be still to use to dig the form of construction work filled out greatly greatly, i.e., usually said heavy excavation mode, but it is not environmentally friendly enough, especially
Its for mountain area rock geology, heavy excavation mode not only construct it is especially difficult, since the structural behaviour of rock could not be played, fully
Utilize the advantage of undisturbed soil (rock) so that foundation excavation amount is larger, and investment is higher, also brings spoir problem, soil erosion
Problem.So it is not extensive for mountain area popularization gravity assembling type base, it mostly uses raw fly ash greatly at present and such as draws digging, pile foundation
Plinth and Rock Bolt Foundation.
2. traditional gravity type assembling type base
Traditional gravity type assembling type base, no matter several patterns such as pyramid support rack type, tower leg baried type, metal foundation are all
It is to place a stent into backfill in the soil, necessary anti-corrosion measure (such as anti-corrosion painting etc.) is clear though taking, in water and electrolyte
Dual corrosion under, durability is a greater impact, there is presently no at all effective anti-corrosion.
Therefore, the efficiency of assembling of cushion cap anchor rod foundation how is improved, material is saved, is that those skilled in the art need at present
The technical issues of solution.
