Abstract
Provided is an oblique column base of a UHV DC transmission line, comprising a reinforced concrete large plate (101) and an oblique main column (102) disposed thereabove. The oblique main column (102) is a reinforced concrete square-shaped column. The cross section center (A) of the oblique main column (102) overlaps with the center (B) of the reinforced concrete large plate (101). The oblique main column (102) inclines along the center direction of a tower. The oblique column base of a UHV DC transmission line is advantageous in that bending moment of an upper tower force applying on the base can be reduced; the sizes of a bottom plate and the main column can be decreased; engineering amount of concrete, steel bars and foundation pit earthwork can be declined.
Description
Technical field
The utility model relates to the High-Voltage Technology field, is specifically related to a kind of batter post basis of extra high voltage direct current transmission line.
Background technology
The under ground portion of electric power line pole tower totally be referred to as the basis.Its effect is the shaft tower that is used for supporting transmission line of electricity.Basic is of a great variety, comprises Rock Embed based, digging foundation, notch cuttype basis, big plate base, bored pile.Wherein, the primary features of big plate base is: base plate is big, and buried depth is shallow, base plate is thinner, leans on the base plate two way system to bear moment of flexure and the shearing that causes with horizontal force by pulling out on the shaft tower, pressing down, and principal post calculates identical with the ladder basis.Compare with the ladder basis, buried depth is shallow, is prone to excavation and is shaped, and amount of concrete is lower, but the reinforcing bar amount increases, and compares with castinplace pile, in general soft soil foundation, uses comparatively extensive.
The inventor is through discovering the pole and tower foundation active force of existing big plate base and extra-high voltage direct-current circuit; Existing big plate base is if be used for the extra-high voltage direct-current overhead line structures; Because the general DC line shaft tower of basic role power is a lot of greatly; Cause base plate and principal post size bigger, engineering quantitys such as concrete, amount of reinforcement and pit earthwork all increase greatly.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned existing disadvantages of background technology part, and a kind of batter post basis of extra high voltage direct current transmission line is provided.It can reduce the moment of flexure that top shaft tower active force produces the basis, thereby reduces the size of base plate and principal post, reduces the engineering quantity of concrete, reinforcing bar and pit earthwork.
The purpose of the utility model reaches through following measure: the batter post basis of extra high voltage direct current transmission line; It is characterized in that it comprises: big plate of steel concrete and the inclination principal post that upward is provided with thereof; Said inclination principal post is the steel concrete square column; Center, said inclination principal post bottom section overlaps with the big plate of said steel concrete center, and said inclination principal post tilts along the shaft tower center position.
In technique scheme, said inclination principal post cross section is a square, and said inclination principal post top plan keeps level.
In technique scheme, in the said inclination principal post plug-in type angle steel is arranged, described plug-in type angle steel is connected with the iron tower column foot.
In technique scheme, the big plate of said steel concrete is a square.
In technique scheme, the convex on the big plate of said steel concrete, described inclination principal post is arranged on the convex.
In technique scheme, the concrete cushion of laying in the big plate of described steel concrete bottom surface.
The utility model extra-high voltage direct-current batter post basis can reduce the moment of flexure that top shaft tower active force produces the basis, thereby reduces the size of base plate and principal post, reduces the engineering quantity of concrete, reinforcing bar and pit earthwork.
Description of drawings

The plan view on the batter post basis that Fig. 2 is provided for the utility model embodiment one.
The elevation on the batter post basis that Fig. 3 is provided for the utility model embodiment two.
The plan view on the batter post basis that Fig. 4 is provided for the utility model embodiment two.
Fig. 5 is for being suitable for the top shaft tower sketch map of the utility model.
The big plate of 101. steel concrete among the figure, 102. inclination principal posts, 103. concrete cushions, 104. plug-in type angle steel, 105. convexes, center, A. inclination principal post bottom section, the big plate of B. steel concrete center, C. iron tower center.
The specific embodiment
Below in conjunction with the performance of accompanying drawing detailed description the utility model, but they do not constitute the qualification to the utility model, only do for example.Advantage through explanation the utility model will become clear more and understanding easily simultaneously, and the direction among the figure shown in the arrow is a line direction.
Consulting accompanying drawing can know: the batter post basis of the utility model extra high voltage direct current transmission line; It comprises: big plate 101 of steel concrete and the inclination principal post 102 that upward is provided with thereof; Said inclination principal post 102 is the steel concrete square column; Said inclination principal post 102 bottom section center A overlaps with the big plate 101 center B of said steel concrete, and said inclination principal post 102 tilts along the shaft tower center position.Inclination principal post 102 cross sections are square, and said inclination principal post 102 top plan keep level.Plug-in type angle steel 104 is arranged in the inclination principal post 102, and described plug-in type angle steel 104 is connected with iron tower column foot 502.The big plate 101 of steel concrete is a square (like Fig. 1, Fig. 2, shown in Figure 5).
Convex 105 on the big plate 101 of steel concrete, described inclination principal post 102 is arranged on the convex 105.The concrete cushion of laying in the big plate of described steel concrete 101 bottom surfaces 103 (like Fig. 3, shown in Figure 4).
Need to prove: the computational methods of the big plate of steel concrete are consistent with the base plate computational methods on conventional basis; But because principal post tilts; The shaft tower load reduces than the right cylinder basis through the moment of flexure value that principal post is delivered to sole plate greatly; Therefore the size of the big plate 101 of steel concrete can reduce greatly, and the thickness of base plate is also less simultaneously.In like manner, the moment of flexure that inclination principal post 102 receives the also moment of flexure than right cylinder is little, and therefore required principal post sectional dimension is little and the reinforcing bar configuration is also less than right cylinder.
Relative shaft tower center, four single footings layout that is centrosymmetric in the utility model.
In the utility model four independently batter post basis be connected with shaft tower column foot 502 connected modes employing plug-in type angle steel.The pre-buried plug-in type angle steel 104 in inclination principal post center.
The big plate form of the utility model embodiment steel concrete can adopt the form among Fig. 1 or Fig. 3 according to result of calculation.
In the present embodiment, in order to guarantee the construction quality of the big plate of steel concrete, can be at its floor pavement concrete cushion 103.
Other unspecified part is prior art.
