Problems solved by technology
[0002] There are widely distributed soft soil foundations with high compressibility in the eastern coastal areas of my country. A large number of power transmission and transformation equipment and transmission towers are built on this soft soil foundation. Due to various reasons, some power transmission and transformation equipment and transmission towers are in operation. Large uneven settlement of the foundation occurred in the middle, because these equipment need to carry out the foundation deviation correction operation under the electrified state, the height of the working space is limited, and the existing pile-forming methods and pile-forming equipment are difficult to apply

The invention discloses a static pile pressing device suitable for error correction of a transmission tower foundation. The static pile pressing device comprises a short groove steel corbel with a steel anchor plate, double angle counter-force frames with top plates, a double-acting jack, a manual hoop connected with the double-acting jack and a connecting batten plate connected between the two double angle counter-force frames. The static pile pressing device suitable for error correction of the transmission tower foundation is small in total height and light in total weight, the transportation and construction process does not need the assistance by a large machine, and the operation space height limitation requirements of electrification operation error correction of a power transmission device and the transmission tower foundation are met; original foundation self weight is utilized to provide pile pressure, an anchor rod and the like do not need to be arranged to provide counter-force, the construction is convenient and fast, and the pile forming process is fast and has no noise pollution to the environment. The manual hoop operation in the static pile pressing device suitable for error correction of the transmission tower foundation is simple and convenient, friction needed for pile pressure can be provided stably, quick dismantling can be performed, and the pile pressing speed is improved.
Description
technical field [0001] The invention belongs to the field of construction engineering pile foundation technology and construction, in particular to a static pile pressing device and an operation method suitable for deflection correction of transmission tower foundations. Background technique [0002] There are widely distributed soft soil foundations with high compressibility in the eastern coastal areas of my country. A large number of power transmission and transformation equipment and transmission towers are built on this soft soil foundation. Due to various reasons, some power transmission and transformation equipment and transmission towers are in operation. Large uneven settlement of the foundation occurred in the middle, because these equipment need to carry out the foundation deviation correction operation under the live state, the height of the working space is limited, and the existing pile-forming methods and pile-forming equipment are difficult to apply.
