Specific embodiment

The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

As shown in Figure 1, being a kind of structural representation of double anchor slab bases fixed structure of transmission line of electricity joint plate stem of the present invention Figure, including sheet-pile 5 and board group, board group include top-down first daughter board 1 and the second board group, and the second board group includes two independences The second daughter board 2 being arranged；

It further include anchor rod component, anchor rod component includes the first anchor pole 3 and the second anchor pole 4, and sheet-pile 5 passes through with the first daughter board 1 First anchor pole 3 is affixed, and the first daughter board 1 is affixed by the second anchor pole 4 with two the second daughter boards 2 respectively.

The quantity of first anchor pole 3 has multiple.Multiple first anchor poles 3 successively axially penetrate through sheet-pile 5 and the first daughter board 1, multiple The both ends of first anchor pole 3 are affixed by bolt with the first daughter board 1 and sheet-pile 5 respectively.

The quantity of first anchor pole 3 has 4.

The quantity of second anchor pole 4 is two.

Two the second anchor poles 4 axially penetrate through two the second daughter boards 2 respectively, two 4 one end of the second anchor pole with the second daughter board 2 Cross that bolt is affixed, the other end of two the second anchor poles 4 axially penetrates through the first daughter board 1 and solid by bolt with the first daughter board 1 respectively It connects.

The both ends of first anchor pole 3 are equipped with steel plate 6, and one of steel plate 6 is arranged between bolt and sheet-pile 5, another Steel plate 6 is arranged between bolt and the first daughter board 1, and one end of the second anchor pole 4 is equipped with steel plate 6, and one end of steel plate 6 is arranged in bolt Between the second plate 2.

Gasket 7 is equipped between first anchor pole 3 and steel plate 6 on the second anchor pole 4 and the bolt closed on.

Outer on first anchor pole 3 and the second anchor pole 4 to be cased with erosion resistant coating, erosion resistant coating includes anticorrosive casing pipe, anticorrosive casing pipe difference Anti-corrosion material is filled between the first anchor pole 3 and the second anchor pole 4.

Sheet-pile 5 is partly embedded in underground in construction, and the height that sheet-pile 5 leaks out bottom surface is at least 200mm.

The main function of all parts of the present invention are as follows:

1, sheet-pile 5 is that armored concrete pours, the main function of sheet-pile 5 be for transmitting and undertaking upper pressure, Sheet-pile 5 is partly embedded in underground in construction simultaneously, and anchoring mechanism is basseted, and is conducive to the maintenance of shaft tower anchoring mechanism and anchoring The anti-corrosion of body.

2, the first daughter board 1 is armoured concrete slab, and main function is the pressure for bearing the transmitting of top transmission tower, resists Part uplift load and uplift load is provided for two the second daughter boards 2.Two 2 shapes of the second daughter board are identical, are truncated cone-shaped Armoured concrete slab, the main function of two the second daughter boards 2 are resistant to most of uplift force of transmission tower transmitting.

3, the first anchor pole 3 and the second anchor pole 4 are round steel pipe, and erosion resistant coating is arranged in the outside of anchor pole, and the erosion resistant coating is by anti-corrosion Material and casing are constituted, and casing can also ensure the sliding between anchor pole and plate body, so that it is guaranteed that upper plate mainly undertakes transmission tower The lower pressure of transmitting, the first anchor pole 3 is used to transmit uplift force and resists the shearing force between short column and the first daughter board 1, to protect Hinder the stability on basis；The main function of second anchor pole 4 is to bear and transmit uplift load, while resisting electric power pylon to sheet-pile 5 horizontal forces applied prevent short column and upper plate from generating sliding.

4, steel plate 6 is mainly used for increasing forced area, and the steel plate 6 on the first daughter board 1 is mainly used for giving transmitting transmission tower It passes to and pulls out forced area on the load and increase of the first daughter board 1；Steel plate 6 on second daughter board 2 mainly gives two the second daughter boards 2 Uplift load is provided, the intensity of the second daughter board 2 is improved, while increasing the forced area of bolt and the second daughter board 2.

The double anchor slab foundation structures of transmission tower joint plate stem proposed by the present invention, have power transmission condition clear, resist live load Loading capability is strong, and safety reliability is high, easy construction, and low cost can be used for deep-etching area, frost heaving resistant and thaw collapsibility and can wait spies well Point.The basis can be used for single anchor slab resistance to plucking and hold compared to single anchor slab foundation structure, the double anchor slabs of transmission line of electricity joint plate stem of the present invention Carry the inadequate transmission line foundation of power.
