Tower foundation and manufacturing method thereof

Abstract

The invention discloses a tower foundation and a manufacturing method thereof, and belongs to the technical field of power transmission lines. The tower foundation comprises a prefabricated body, a bearing platform, a plurality of pile bodies, a plurality of first connecting pieces and a plurality of second connecting pieces, wherein the prefabricated body, the bearing platform, the pile bodies, the first connecting pieces and the second connecting pieces are sequentially arranged from top to bottom; a shock insulation pad is arranged between the prefabricated body and the bearing platform, and the upper surface and the lower surface of the shock isolation pad abut against the prefabricated body and the bearing platform separately; each pile body is connected with the lower end of the bearing platform; the upper end of each first connecting piece is arranged in the prefabricated body, and the lower end of each first connecting piece penetrates through the shock isolation pad to be fixed in the bearing platform; the upper end of each second connecting piece is connected with a tower, and the lower end of each second connecting piece sequentially penetrates through the prefabricatedbody and the shock isolation pad to be fixed in the bearing platform; gaps are formed between the first connecting pieces and the prefabricated body as well as between the second connecting pieces andthe prefabricated body, the upper ends of the first connecting pieces are correspondingly sleeved with first spring washers, and the upper ends of the second connecting pieces are correspondingly sleeved with second spring washers; and when an earthquake happens, the bearing platform can drive the first connecting pieces and the second connecting pieces to swing in the corresponding gaps with thefirst spring washers and the second spring washers as base points.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a tower foundation and a preparation method thereof. Background technique [0002] As an important part of the transmission line, the tower foundation is set between the tower and the foundation to transfer the force of the tower to the foundation smoothly and smoothly without causing instability of the foundation. When the transmission line passes through a high seismic intensity area where the site soil is saturated sandy soil or saturated silt, if an earthquake occurs in this area, the foundation will be liquefied due to the impact of the earthquake, causing the tower foundation to vibrate, and further affecting the tower and its load. Power lines are affected. [0003] In order to solve the above problems, the prior art usually adopts the soil cushion method and the deep foundation method. The method of replacing the soil cushion layer is to first use plain...

Problems solved by technology

[0005] If the saturated sandy soil or saturated silt soil in the high seismic intensity area is located in the deep soil layer, the use of soil replacement cushion is not conducive to replacing the cushion layer with saturated sandy soil or saturated silt soil, which will increase the work intensity and Operating time; using the deep foundation method, the size of the foundation needs to be increased, thereby increasing the project cost, and its anti-seismic effect is greatly affected by the local soil layer, which is not conducive to the anti-seismic effect
