Problems solved by technology

[0004] Due to coal mining, the surface of the coal mining area is deformed, and the towers of the transmission lines erected on the coal mining area are tilted, dislocated, bent, or even collapsed, which affects the safety of the transmission line.
The general solution in the existing technology is to relocate and change the route before coal mining, that is, to replace the transmission line section with potential safety hazards with a new line
But this method has great disadvantages. First, due to the relatively large coal mining area, the number of towers that need to be relocated is large, and the construction cost of relocation is relatively high. Second, relocation generally causes long-term and large-scale power outages on the line. , causing a great loss to electricity sales or a great threat to the stable and safe operation of the power grid, causing great impact and loss on social life and production and construction, and may also cause power outages in adjacent lines; third, the most important With the advancement of coal mining operations, the newly relocated lines may still face the problem of relocation, etc.

Embodiment 1

[0033] Such as Figure 1-Figure 5 As shown, the self-adjusting foundation of the double-pole gate-type pole tower of the transmission line in Embodiment 1 of the present invention, in this embodiment, the foundation beam frame is in the shape of "I", and the two ends of the connecting main beam 1 are respectively provided with vertically connected Adjust the secondary beam 2, the two ends of the adjustable secondary beam 2 are respectively equipped with a cable ring 5, two adjustable secondary beams 2 and a connecting main beam 1 form an "I"-shaped foundation beam frame, and the holes on the connecting main beam 1 9 is the position of the wire rod, carbon fiber is pasted on the wire rod to improve its strength, in addition, it can also be reinforced by wet method to improve its strength. In addition, the position connected to the connecting main beam 1 may be subjected to relatively large bending moment and shear force, and the height of the steel plate outside it can be appro...

Embodiment 2

[0040] Such as Figure 6 and Figure 7 As shown, one of the main differences between Embodiment 2 and Embodiment 1 is that abutment piers 31 are respectively set under the two ends of the adjustment secondary beam 2 to support and cooperate with the adjustment of the secondary beam 2, so as to replace the bearings in Embodiment 1. platform beam 3; in addition, what is set between the bearing platform pier 31 and the adjustment secondary beam 2 is a rolling ball ( Figure 7 not shown in), Figure 7 A plurality of rolling balls are provided in the gap between the cap pier 31 and the adjusting secondary beam 2, and the setting of the rolling balls can allow relative translation between the cap pier 31 and the adjusting beam 2 in any direction. In the same way, the rolling ball here can also be replaced by rollers. Similar to Embodiment 1, it is also possible to connect the main beam 1 to be equal to the distance between the two utility poles. In this case, the adjustment secon...

Embodiment 3

[0042] Such as Figure 8 As shown, the main difference between the third embodiment and the second embodiment is that the structural layout of the foundation beams is different, generally in the shape of a "day". The two ends of the connecting main beam 1 are not only directly connected vertically with the wire rod, but also vertically connected with the horizontally arranged vertical connecting beam 22 respectively passing through the same point of the wire rod; Adjust the secondary beam 11 while connecting the main beam 1, and adjust the secondary beam 11 to connect with the vertical connecting beam 22, and extend a certain length to both ends respectively, that is, adjust the two ends of the secondary beam 11 to be longer than the connecting main beam 1, The bottoms of both ends of the side adjustment secondary beam 11 are respectively provided with abutment piers 31, which connect the main beam 1 with the two side adjustment secondary beams 11 and the vertical connecting b...

Abstract

The invention discloses a self-adjusting foundation for a double-pole door-type pole tower of a power transmission line, which comprises a foundation beam frame and a bearing platform beam or a bearing platform pier located below the foundation beam framework and in contact with the foundation, the foundation beam framework and the bearing platform beam or bearing platform There are rolling parts between the piers; the foundation beam frame includes at least one connecting main beam connected to the root of each wire rod and adjusting secondary beams vertically connected to the two ends of the connecting main beam, and the upper surface of each adjusting secondary beam Each is provided with a wire ring; the wire rod is connected with the foundation beam frame through the wire to form a whole, the upper end of each wire is connected with the wire rod, and the lower end is connected with the wire ring. The invention makes the pole and tower into a whole through the foundation beam frame and the stay wire, and under the action of external force, the pole tower remains stable as a whole, does not overturn as a whole, and the stress and deformation of the line pole do not exceed the standard. When the ground is deformed, after part of the constraints are released, the cap beam or cap pier of the pole tower system moves with the deformation of the foundation, the pole maintains a vertical posture, and the line maintains a normal operating state.

Description

technical field [0001] The invention relates to the foundation of a power transmission line, in particular to a self-adjusting foundation of a double-pole door-type pole tower for a power transmission line. Background technique [0002] As an important part of the transmission line, the tower structure plays the role of supporting and overhead power lines (conductors) to ensure safe and reliable transmission of electric energy to the grid or users. The tower structure is mainly divided into two categories: reinforced concrete pole and iron tower in terms of the materials used. Among them, the double-pole door-type pole tower made of reinforced concrete is a relatively common tower structure, which is often used in 35kV-110kV transmission lines. [0003] Many transmission lines often need to pass through the coal mining area or the coal in the lower part of the transmission line that has been in operation needs to be mined, and the ground subsidence and deformation will inevi...
