Abstract
The utility model mainly relates to a connection method of an iron tower and a foundation in the power transmission and distribution project, in particular to an inclined-inserted vertical excavated foundation of a combined angle iron, and the inclined-inserted vertical excavated foundation of a combined angle iron consists of a combined angle iron (1), an anchoring piece (2), a plate shoe (3) of a tower leg brace, a backing plate (4) and a tower leg brace (5). The inclined-inserted vertical excavated foundation of the combined angle iron is characterized in that the combined angle iron (1) is connected with the plate shoe (3) of the tower leg brace and the anchoring piece (2), wherein the combined angle iron (1) is welded with the anchoring piece (2), the backing plate (4) is filled below the combined angle iron (1) and the anchoring piece (2), and the plate shoe (3) of the tower leg brace is connected with the backing plate (4) and the tower leg brace (5).
Description
Technical field
The utility model is primarily aimed at iron tower and basic method of attachment in the project of transmitting and converting electricity, is specially the straight digging foundation of combination angle steel oblique inserting.
Background technology
Transmission line of electricity is in the mountain area mostly; the mountain route main design problems is exactly the stable problem of tower position ground; protecting the initial land form landforms is important means of guaranteeing that column foot is stable; therefore the design of mountain route is to adopt unequal leg and not contour Base Design to avoid the heavy excavation of column foot according to the initial land form landforms on the one hand; adopt the undisturbed soil basis to reduce the excavation of the foundation pit earth cubic meter of stone on the other hand as far as possible; avoid disturbance to column foot; by the enforcement of this two aspect, present transmission line of electricity has been realized the design concept of environmental protectionization substantially.
At present, when national line adopts the undisturbed soil basis, iron tower connects with generally adopting stone bolt being connected of basis, along with fast development of national economy, electricity needs is increasing, the isochrone paths is also more and more crowded, thereby the power grid construction that more and more needs multiloop and extra-high voltage satisfies growing electricity needs, the increase of line loop number and the raising of electric pressure mean that promptly the iron tower that supports circuit increases with basic outer load, at this moment, the undisturbed soil basis still adopts stone bolt to connect, four stone bolt commonly used have not satisfied the requirement of outer load, need eight stone bolt even 12 stone bolt, corresponding column foot plate then sharply strengthens when adopting eight stone bolt even 12 stone bolt, the column foot plate all adopts welding to form one meter square integral body, weight often reaches about one ton, transportation of the column foot plate of one meter square one ton of weight and installation exist very big difficulty and potential safety hazard for mountain route, exist on material because the problem of the blocked up lamellar tearing of column foot plate simultaneously.
Summary of the invention
The utility model provides a kind of convenient transportation just at above technical problem, and the straight digging foundation of combination angle steel oblique inserting of safety is installed easily.
Concrete technical scheme of the present utility model is as follows:
The straight digging foundation of combination angle steel oblique inserting, the oblique material of boots plate, backing plate and tower leg by combination angle steel, anchoring piece, the oblique material of tower leg is formed, the combination angle steel is connected with the boots plate and the anchoring piece of the oblique material of tower leg, combination angle steel and anchoring piece weld together, below combination angle steel and anchoring piece, be lined with backing plate, the boots plate of the oblique material of tower leg is connected with backing plate, and the boots plate of the oblique material of tower leg is connected with the oblique material of tower leg.
Described combination angle steel is a double angle, is " ten " font and arranges.
It is to come load by anchoring piece that the stressed of angle steel inserted in combination.
Technique effect of the present utility model shows: adopt the combined type angle steel, right cylinder undisturbed soil basis ideally combines both, has solved the transportation problem of mountain route, has also solved environmental protection problem, has also saved material simultaneously, has saved construction investment.

The specific embodiment
The utility model is described in further detail below in conjunction with the specific embodiment and Figure of description
Specific embodiment:
The straight digging foundation of combination angle steel oblique inserting, the oblique material 5 of boots plate 3, backing plate 4 and tower leg by combination angle steel 1, anchoring piece 2, the oblique material of tower leg is formed, combination angle steel 1 is connected with the boots plate 3 and the anchoring piece 2 of the oblique material of tower leg, combination angle steel 1 welds together with anchoring piece 2, below combination angle steel 1 and anchoring piece 2, be lined with backing plate 4, the boots plate 3 of the oblique material of tower leg is connected with backing plate 4, and the boots plate 3 of the oblique material of tower leg is connected with the oblique material 5 of tower leg.
Described combination angle steel 1 is a double angle, is " ten " font and arranges.
Described combination is inserted the stressed anchoring piece 2 that leans on of angle steel and is born, and the intensity that angle steel is inserted in combination is calculated as
A
N---the net cross-sectional area of angle steel, mm are inserted in combination
2
N---the pulling force or the pressure of angle steel, N are inserted in combination
V
s---perpendicular to the shearing of combination insertion angle steel, N
The bearing capacity of anchoring piece 2 is for being example with the angle steel anchoring piece:
The bearing capacity of single anchoring piece 2:
Angle steel anchoring piece number:
T---the limb of angle steel anchoring piece is thick, mm
The R arc of r---angle steel anchoring piece, mm
f
c---the compressive strength design load of base concrete, N/mm
2
L---the length of angle steel anchoring piece, mm
f
c---the compressive strength design load of base concrete, N/mm
2
L---the length of steel anchoring piece, mm
The minimum buried depth of angle steel is inserted in combination
A---the gross cross-sectional area of angle steel, mm are inserted in combination
2
f
u---the minimum tensile strength standard value of steel, N/mm
