Specific embodiment

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

As shown in Figure 1, combine the main view of three anchor slab basis fixed structure of plate stem for a kind of transmission line of electricity of the present invention, including Sheet-pile 5 and board group, sheet-pile 5 are partly embedded in underground in construction, and the height that sheet-pile 5 leaks out bottom surface is at least 200mm, can be with tower Sole is attached.

Board group includes the first daughter board 1 being arranged from top to bottom and the second board group, and the second board group includes three and is independently arranged Second daughter board 2；

As shown in Figure 2,3, the vertical view of a kind of transmission line of electricity joint three anchor slab basis fixed structure of plate stem respectively of the invention Figure and bottom view further include anchor rod component, and anchor rod component includes the first anchor pole 3 and the second anchor pole 4, and the first daughter board 1 and sheet-pile 5 are logical It crosses the first anchor pole 3 to be connected, the first anchor pole 3 is provided with 4, and each first anchor pole 3 successively axially penetrates through sheet-pile 5 and the first daughter board 1, the both ends of each first anchor pole 3 are affixed by bolt with sheet-pile 5 and the first daughter board 1 respectively；First daughter board 1 respectively with three Two daughter boards 2 are connected by the second anchor pole 4, and the second anchor pole 4 is identical as the quantity of the second daughter board 2 and position corresponds, each Second anchor pole 4 successively axially penetrates through the first daughter board 1 and corresponding second daughter board 2 of the first daughter board 1, and the two of each second anchor pole 4 End is affixed by bolt with the first daughter board 1 and the second daughter board 2 respectively.

Three the second daughter boards 2 are the truncated cone-shaped plate that armored concrete is cast, whole distribution triangular in shape, with single anchor slab Foundation structure is compared with double anchor slab foundation structures, can be dramatically increased the stability of joint plate stem, be greatly enhanced service life.

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 the both ends of the second anchor pole 4 are equipped with steel plate 6, and one of setting of steel plate 6 exists Between bolt and the first plate 1, another steel plate 6 is arranged between bolt and the first plate 2, and the first anchor pole 3 and second Gasket 7 is equipped between steel plate 6 on 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, the anticorrosive casing pipe Anti-corrosion material is filled between the first anchor pole 3 and the second anchor pole 4 respectively.

Column foot plate is directly connected with four first anchor poles 3.

The main function of breeding pigeon main component of the present invention are as follows:

First daughter board 1 is armoured concrete slab, and main function is the pressure for bearing the transmitting of top transmission tower, bears part Uplift load gives 34 transmitting portions uplift loads of the second anchor slab.

The main function of sheet-pile 5 is that anchoring mechanism bassets, and is conducive to the maintenance of shaft tower anchoring mechanism and anchoring body Anti-corrosion；Sheet-pile 5 and the first daughter board 1 are mutually independent component, are connected by the first anchor pole 3；Sheet-pile 5 is for transmitting and undertaking top Pressure, the main function of the first anchor pole 3 are to bear and transmit uplift load, while resisting the level that electric power pylon applies to short column Power prevents sheet-pile 5 and the first daughter board 1 from generating sliding, and sheet-pile 5 can prefabricated also cast in situs.

Three the second daughter boards 2 are mainly used for resisting most of uplift force of transmission tower transmitting, are reinforced concrete structure.

First anchor pole 3 and the second anchor pole 4 are round steel material, erosion resistant coating are arranged outside anchor pole, the erosion resistant coating is by preserving timber Material and casing are constituted, and casing can ensure and can mutually slide between anchor pole and sheet-pile 5, so that it is guaranteed that the first daughter board 1 mainly undertake it is defeated The lower pressure of electric pole tower transmitting.

Three anchor slab foundation structures of the invention mainly solve transmission tower joint plate stem list anchor slab basis, transmission tower joint The case where double anchor slab bases of plate stem can not provide enough resistance to plucking loads.
