Portable water injection type rotary excavating equipment for tower footing pile hole construction in mountainous and hilly areas

Abstract

The invention provides portable water injection type rotary excavating equipment for tower footing pile hole construction in mountainous and hilly areas. The equipment comprises a first machine base,a rotary excavating feeding module, a rotary excavating direction adjusting module, a rotary excavating module and a mud-water separation system which are all fixed on the ground; the rotary excavating feeding module comprises an axial telescoping jacking mechanism, a jacking block, and a jacking tube; the rotary excavating direction adjusting module comprises a second machine base, and an axial telescopic adjusting jacking mechanism and an adjusting positioning plate which are both arranged in the second machine base and used for adjusting the rotary excavating feeding direction; the rotary excavating module comprises a third machine base, and a driving motor, a speed reducer and a cutter disc which are all mounted on the third machine base; and the mud-water separation system comprises awater source, a separation tank, a sediment pump and a connecting pipeline, wherein the water source and the separation tank are located on the ground, and the sediment pump and the connecting pipeline are arranged on the adjusting positioning plate in the second machine base. The equipment has the advantages of compact and simple structure, convenient disassembly and assembly, small size and light weight, and is convenient to transport in the mountainous and hilly areas.

Description

[0001] The invention relates to the technical field of pile hole excavation for civil foundation construction, and more specifically, relates to a portable water-injection rotary digging device used for excavating foundation pile holes of transmission line iron towers and wind power tower foundations in mountainous and hilly areas. [0002] technical background [0003] With the continuous acceleration of infrastructure construction, mechanized construction has been widely used in various fields. Due to the complex construction environment, scattered tower foundations, inconvenient transportation and many other reasons in the construction of transmission lines, mechanized construction has been greatly limited. Traditional construction methods have problems such as low construction efficiency and high labor intensity, which have been difficult to adapt to the rapid development of transmission lines. In recent years, the State Grid Corporation of China has been committed to the re...
