The present invention discloses a multi-purpose exploration
adit layout method. It includes the following steps: Step 1: Drafting the position of the longitudinal tunnel section DOC and determining the positions of points D, O, and C on the
adit axis; Step 2: Drafting the position of the transverse tunnel section CB and determining the position of point B on the
adit axis; Step 3: Drafting the position of the oblique tunnel section BA and determining the position of point A on the adit axis; Step 4: After the positions of points D, O, C, B, and A have been determined in sequence, the
layout of the exploration adit is determined; during actual adit construction, the adit construction excavation is carried out in the
reverse order of points A, B, C, O, and D, and the oblique tunnel section BA, transverse tunnel section CB, and longitudinal tunnel section DOC are excavated in this order. The present invention not only realizes the multi-purpose of
landslide investigation, sampling, testing, drainage, etc. in the adit, but also has the advantages of safe construction,
cost savings, and shortened construction period.
