Abstract
A kind of joint pylon pile foundation, it is made of four pylon pile foundation connections, each pylon pile foundation includes cushion cap and stake, it is characterized in that, four pylon pile foundations are located at a square corner location, and the cushion cap of each pylon pile foundation is connect with the cushion cap of other three pylon pile foundations by reinforcing bar.In each pylon pile foundation, cushion cap lower central position anchors a vertical stake one, multiple stakes two around the center is also set up below cushion cap, and each stake two is tilted to the direction far from the center.Traditional electric tower foundation pattern is transformed for the loading characteristic of the electric tower foundation in the side slope of goaf, improves the stability of the electric tower foundation near goaf by the present invention.
Description
Technical field
The invention belongs to project of transmitting and converting electricity equipment technical field, it is related to a kind of joint pylon pile foundation more particularly to early warning
The continuously adjustable of ultra-high-tension power transmission line pylon resists mined out basis in the mined out side slope in mountainous region in phase.
Background technique
In recent years, the electric power development in China is very rapid, the route selection of transmission line of electricity inevitably by coal mine gob,
Transmission line of electricity column foot is often built in side slope, and side slope lower part is commonly present the baleful geological processes such as goaf or karst.By side
The collective effects such as slope, goaf or karst, often there is situations such as failure, damaged in column foot in side slope, influences the safety fortune of column foot
Row.Transmission line of electricity moves that the expenses such as to change and repair huge, and has the tendency that growing.Laying and power network due to transmission line of electricity
The construction demand of point constantly increases, and the selection space of route evacuation further reduces, and column foot is damaged on route, safeguards or causes
Economic loss caused by power breakdown is increasingly huge.As the propulsion of China's new energy strategy is goed deep into what smart grid was built,
Risk prevention system and Forewarning Measures will be proposed more accurately to require.Existing column foot design method is unable to the mined out work of reasonable consideration
With, need carry out further investigation.
Summary of the invention
In order to overcome the disadvantages of the above prior art, the purpose of the present invention is to provide a kind of joint pylon pile foundation, needles
To the loading characteristic of the electric tower foundation in the side slope of goaf, traditional electric tower foundation pattern is transformed, is improved mined out
The stability of electric tower foundation near area.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of joint pylon pile foundation is made of four pylon pile foundation connections, and each pylon pile foundation includes 1 He of cushion cap
Stake, which is characterized in that four pylon pile foundations are located at a square corner location, the cushion cap of each pylon pile foundation
1 is connect with the cushion cap 1 of other three pylon pile foundations by reinforcing bar 3.
In each pylon pile foundation, 1 lower central position of cushion cap anchors a vertical stake 1, and 1 lower section of cushion cap is also set
Multiple stakes 2 22 around the center are set, and each stake 2 22 is tilted to the direction far from the center.
The stake 2 22 and the relativeness of slip-crack surface are close to vertical.
In each pylon pile foundation, remoter 2 22 tilt angle of stake in distance center position is bigger.
In each pylon pile foundation, with the equidistant each stake 2 22 in center, tilt angle is identical.
It is 30 ° positioned at the stake 2 22 at 1 edge of cushion cap and the angle of 1 bottom surface of cushion cap in each pylon pile foundation.
In each pylon pile foundation, between cushion cap 1 and stake 1 and between cushion cap 1 and stake 2 22, pass through steel
Muscle anchoring.
Each reinforcing bar 3 is generally aligned in the same plane, wherein two reinforcing bars 3 of square interior form criss-cross construction.
Compared with prior art, the beneficial effects of the present invention are:
1) utilization efficiency for improving friction pile increases the coverage of friction pile, to reduce costs.
2) globality of electric tower foundation is enhanced, whole rigidity is improved, pylon is made to resist uneven settlement of foundation
Ability enhancing.
3) compared with big plate basis, cost of the present invention is lower, and is more convenient for safeguarding and overhaul.
Detailed description of the invention
Fig. 1 is the pile arrangement schematic diagram of single pylon pile foundation of the invention.
Fig. 2 is the connected mode schematic diagram between four electric tower foundations of the invention.
Specific embodiment
The embodiment that the present invention will be described in detail with reference to the accompanying drawings and examples.
The present invention combines pylon pile foundation and is made of four pylon pile foundation connections, thes improvement is that:
1. the arrangement of single pylon pile foundation.
According to the slope deforming characteristic in goaf, underground mining empty condition has a certain impact region to above covering side slope, may
Causing geological disasters, the electric tower foundations near slip-crack surface such as landslide can all be affected.The present invention arranges conventional vertical
Pile foundation be changed to be in tilted layout, inclined direction is on the outside of tower foundation.This arrangement makes the influence of the pile foundation of equivalent
Range becomes larger, and increases the anti-slide performance of every pile with the relativeness of slip-crack surface, improve whole stake closer to vertical
The antiskid efficiency on basis.
Specifically, as shown in Figure 1, each pylon pile foundation includes cushion cap 1 and stake, pile arrangement are as follows: 1 lower central of cushion cap
Position also passes through the multiple circular centers of Bar Anchorage by Bar Anchorage one vertical stake 1,1 lower section of cushion cap
Stake 2 22, and each stake 2 22 is tilted to the direction far from the center, remoter 2 22 inclination angle of stake in distance center position
Degree is bigger, is 30 ° positioned at the stake 2 22 at 1 edge of cushion cap and the angle of 1 bottom surface of cushion cap, with the equidistant each stake in center
2 22, tilt angle is identical.
2. the connection type of cushion cap.
Connection type between four pylon pile foundations is as shown in Fig. 2, four pylon pile foundations are located at a pros
The corner location of shape, the cushion cap 1 of each pylon pile foundation are connect with the cushion cap 1 of other three pylon pile foundations by reinforcing bar 3
Form an entirety.Wherein, each reinforcing bar 3 is generally aligned in the same plane, and two reinforcing bars 3 of square interior form right-angled intersection
Structure enhances resistivity of the pylon pile foundation in differential settlement to improve the rigidity of pylon pile foundation entirety.
In pylon use process, if the connection reinforcing bar 3 of a certain section of pylon pile foundation is sent out due to uneven settlement of foundation
Destruction is given birth to, therefore other several pylon pile foundations will not be affected, only repair when maintenance and destroy part.
