Abstract
The utility model discloses a whole slab foundation of a power transmission tower. The whole slab foundation of the power transmission tower is characterized in that the whole slab foundation comprises a bottom plate and four uprights evenly distributed on the bottom plate and penetrating through the bottom plate, the four uprights and the bottom plate are integrally formed in a cast mode, multiple transverse bottom plate main ribs and multiple longitudinal bottom plate hooping ribs are arranged on the bottom plate, each upright is provided with multiple longitudinal upright main ribs and multiple transverse upright hooping ribs, and the top of each upright is provided with foundation bolts used for fixing a device. According to the whole slab foundation of the power transmission tower, the four uprights are arranged on the bottom plate and each upright is provided with the foundation bolts so that four devices can be fixed simultaneously, four portions of one device can be fixed to the foundation bolts as well, force can be received in a more balanced mode, the settling volume can be small and even, the capacity of adjustment of differential settlement of the foundation can be strong, and stability can be higher. The main ribs and the corresponding hooping ribs are arranged on the bottom plate and the uprights at the same time, so that the anti-shearing performance of the whole slab foundation of the power transmission tower is enhanced.
Description
Technical field
The utility model relates to a kind of basis, relates in particular to the whole slab foundation of a kind of power transmission tower.
Background technology
Basis is the supporting member that construction bottom contacts with ground, and its effect is that the load on building top is passed to ground, is the important component part of house, bridge, harbour and other structure.Power transmission tower is the tall and slender structure that a kind of engineering quantity is huge and very important.As the electric power facility of important lifeline engineering, power transmission tower is to be transferred the load in ground and gone by basis, and no matter which partly goes wrong or destroys ground or basis, all will top power transmission tower be made a very bad impression and even be caused a serious accident.Complexity due to foundation condition, the particularity of the physico-mechanical properties of soil, people are also exploring and are going deep into its understanding so far, therefore, the design on basis occupies very consequence in super-pressure Design Transmission Line, and the selection of basic pattern is to affect one of Engineering Overall cost principal element.The selection of basis pattern, should be determined in conjunction with each section of landform, hydrogeological situation, execution conditions and power transmission tower pattern, and should, meeting under the prerequisite of rules, standard, be reduced as much as possible construction costs.
Utility model content
The purpose of this utility model is to provide a kind of power transmission tower whole slab foundation, foundation structure is succinct, save material, easy construction, settling amount is little and even, shear behavior good.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions: the whole slab foundation of power transmission tower, it is characterized in that, comprise a base plate, be evenly distributed on base plate and run through four columns of base plate, described four columns and base plate are one cast moldings, on described base plate, be provided with some the main muscle of transverse bottom plate and some longitudinal base plate stirrups, on described each column, be provided with some the main muscle of longitudinal column and some transverse upright stirrups, described each column top is provided with the stone bolt of fixed equipment.
Four columns are set on base plate, on each column, be equipped with stone bolt, can fix four equipment simultaneously, also can be by four partial fixings of an equipment on stone bolt, make stressed more balancedly, settling amount is little and even, the ability of adjusting uneven settlement of foundation is more intense, stability is higher, by corresponding main muscle and stirrup are set on base plate and column simultaneously, has strengthened the shear behavior of the whole slab foundation of power transmission tower.
Further, to be positioned at the height of base plate two side portions identical for each column.
Further, the thickness of described base plate be column height 1/5th to 1/3rd between.
The beneficial effects of the utility model are: the whole slab foundation of power transmission tower can be fixed four equipment simultaneously, also can be by four partial fixings of an equipment on stone bolt, make stressed more balanced, settling amount is little and even, the ability of adjusting uneven settlement of foundation is more intense, stability is higher, by corresponding main muscle and stirrup are set on base plate and column simultaneously, has strengthened the shear behavior of the whole slab foundation of power transmission tower.
