Description
Technical field
The present invention relates to slope column foot technical field, particularly relate to a kind of prefabricated fish belly type barrier formula wing plate basis, be applicable to the power transmission tower foundation on slope, mountain area, for the resistance to capsizing improving slope column foot provides a set of effective method.
Background technology
China is the country on mountain more than, and mountain area area accounts for 2/3 of national total area.Along with the progressively enforcement of the national large-scale transmission of electricity projects such as transferring electricity from the west to the east, become inevitable at Construction of The Mountainous Region transmission line of electricity.Water conservancy, highway and other industry, civilian installation build in, also often run into the situation of building building on the slope.Pass through the work transmission line of Freeway of Mountain Range, its column foot is positioned on slope mostly, will face column foot homeostatic problem during design.Therefore, the resistance to capsizing how improving slope, mountain area column foot is the important topic of pendulum in face of engineers and technicians.
At present, clear and definite normative reference is not also had about the method for designing on basis, slope in current specifications, in order to improve the overturning or slip resistance analysis performance of slope column foot, the depth of burying of traditional independent foundation under column often arranges larger, the economic problems of waste constructional materials will be there are like this, the situation simultaneously easily causing cylinder to fracture because buried depth is excessive, and also can not improve power transmission tower foundation resistance to capsizing on the slope well.
Therefore, in order to improve the resistance to capsizing of slope, mountain area column foot, a kind of economic, reasonable, safe and effective base form of research and development has very important significance.
Summary of the invention
The object of the invention is to there are provided a kind of prefabricated fish belly type barrier formula wing plate basis, this basis adopts prefabricated steel concrete fish belly type wing plate, layering bidirectional, orthogonally through the square cylinder be positioned on conical expansion basis, forms the independent foundation under column of a kind of band completely newly two-way fish belly type wing plate.This foundation structure is simple, easy to operate, effectively can improve power transmission tower foundation rigidity in the horizontal direction and overall stability, can improve the resistance to capsizing of power transmission tower foundation on slope, mountain area.
In order to achieve the above object, the present invention adopts following technical measures:
A prefabricated fish belly type barrier formula wing plate basis, it is by square cylinder, conical expansion basis, prefabricated reinforced concrete fish belly type wing plate, transmission tower leg, square hole, and rim of a cup, structure mortar, the parts such as stone bolt are formed.Its annexation is: square cylinder inserts in the reserved rim of a cup on conical expansion basis; Prefabricated reinforced concrete fish belly type wing plate layering bidirectional penetrates the reserved square hole on described square cylinder orthogonally, forms orthogonal barrier; Transmission tower leg is fixed on the upper end of described square cylinder by stone bolt.
Conical expansion basis is lain against on the foundation ditch ground layer of slope, in the middle of rim of a cup described in square cylinder is inserted, after pouring structure mortar, backfill is added in foundation ditch, be filled to after described rim of a cup upper end 20 ~ 40cm, wing plate is penetrated in the first floor square hole of square cylinder, continue to add backfill and compacting, be filled to after maintaining an equal level with first floor wing plate, in the square hole described in the second layer, penetrate wing plate again, upper and lower two-layer fish belly type wing plate forms orthogonal barrier shape, 2 ~ 6 times so repeatedly, finally foundation ditch is filled it up with backfill, domatic fair with slope after compacting.
The present invention compared with prior art, has the following advantages and effect:
1) prefabricated steel concrete fish belly type wing plate is adopted, directly through the square cylinder of the reserved square hole of band during installation, easy and simple to handle, convenient construction;
2) middle part of prefabricated reinforced concrete fish belly type wing plate is square, and two flanks are trapezoidal shape, so both alleviate the deadweight of wing plate, also saves material simultaneously;
3) square cylinder of square hole is reserved in the layering of prefabricated fish belly type wing plate orthogonally through band along orthogonal both direction, form the orthogonal barrier of multilayer, improve the resistance to overturning of column foot, the resistance to capsizing on the slope of whole column foot will be improved widely like this;
4) square cylinder and conical expansion basis are small-sized concrete prefabricated element, convenient transport, easy to use, decrease in the concrete workload of mountain area job mix.
5) by adjusting prefabricated fish belly type wing plate in the quantity of orthogonal both direction, the specific requirement of different actual conditions to overturning or slip resistance analysis etc. can be adapted to.
Comparative study finds: when slope, slope is than being 1:1, when embedded depth of foundation is 2m, the limit anchorage of conventional foundation is 60KN, and adopt the base form of this patent, after penetrating 4 ~ 8 blocks of fish belly type wing plates, limit anchorage brings up to 73 ~ 92KN, improves about 21.6 ~ 53.3% than the limit anchorage of conventional foundation.
The present invention is reasonable in design, and structure is simple, improves the overturning or slip resistance analysis performance of slope column foot to a great extent, provides a kind of economic, reasonable, safe and effective method to the design of slope column foot in the transmission line of electricity of mountain area
