Description
Technical Field
The invention relates to the field of slope construction equipment, in particular to an excavation device for slope construction.
Background
The side slope generally refers to a mountain side surface with an inclined slope surface formed naturally or artificially, and is one of the most basic geological environments in human engineering activities and the most common engineering form in engineering construction. The side slopes can be classified into natural side slopes and artificial side slopes according to cause; according to the property of the material for forming the side slope body, the material can be divided into a soil side slope and a rock side slope; and can be classified into a stable side slope, a basic stable side slope, an under-stable side slope and an unstable side slope according to the stability degree of the side slope.
Because the slope surface is inclined, the whole slope body has the tendency of sliding from high to low under the action of the self gravity of the slope body and other external forces, particularly under the action of rainfall scouring, and the phenomenon is particularly obvious for unstable slopes and under-stable slopes, so that the slope protection engineering is particularly important. At present, the slope protection mode generally comprises a mesh-pulling type protection mode and an interception type protection mode, wherein the mesh-pulling type protection mode is that various flexible nets mainly comprising steel wire rope nets are covered and wrapped on a slope or rocks to be protected so as to limit weathering spalling or damage of slope rock and soil mass and dangerous rock collapse; the intercepting type protection means that an intercepting plate is fixed at the bottom of a side slope, and the purpose of intercepting falling rocks is achieved. The intercepting protection is usually to pre-embed pillars at the bottom of a slope, fix a connecting plate (usually iron) between two pillars, and utilize the connecting plate to intercept falling rocks. Deep-digging drilling operation is required before the pillars are embedded, the current deep-digging drilling operation is usually completed by a deep-digging machine, but the descending speed (downward moving deep-digging) and the lifting speed (upward moving resetting) of the current deep-digging machine are consistent and are slow; the lifting process does not need deep-digging operation, but only needs a resetting process, and the slow speed of the lifting process can cause the reduction of the overall operation efficiency of deep-digging drilling.
