High-precision multifunctional horizontal spiral drilling rig

Abstract

The invention relates to the field of single-foundation-pit short-distance pipeline excavation tunnel construction, in particular to a bilayer translation rack, a jacking walking device, a driving power device, a rotation device and a pipe-paving direction adjusting device and further comprises an optical guide device, a hoisting device, a hydraulic pump station and an electric appliance cabinet. Stability of the whole drilling rig is improved, structure of the whole drilling rig is improved, and jacking movement tracks are more accurate; the driving power device can be used for driving a drilling stem to rotate and can be used for efficient connection among sleeves, so that pipe paving efficiency is improved; the drilling rig is flexible in construction and high in construction accuracy; the drilling rig is suitable for various strata, diverse in function, convenient and safe to operate and control, low in equipment manufacturing cost, economical and practical.

Description

technical field [0001] The invention relates to the construction field of short-distance pipeline excavation and tunnel construction of a single foundation pit, in particular to a high-precision multifunctional horizontal auger drilling machine. Background technique [0002] Pipeline construction often encounters roads, railways, rivers, houses, etc. that cannot be constructed by open-excavation methods, and underground excavation methods must be used to cross these obstacles. At present, the existing pipeline laying drilling rigs on the market have low guiding precision, the connection efficiency between pipelines is very low, and there must be drill entry and exit points, the function is single, and the construction has great limitations. These pipeline construction machines are also Only some simple construction can be completed, and single-hole construction equipment with precision control is even rarer. With the development and demand of engineering construction, more ...
