Composite hole exploration method combining drilling, Luoyang shovel and drill rod exploration

Abstract

The invention discloses a composite hole exploration method combining drilling, a Luoyang shovel and drill rod exploration. The composite hole exploration method is specifically implemented according to the following steps: on a road surface, after a drilling rig is adjusted, a drilling rig tapper is used for tapping, and hard surface layers of the road surface and a roadbed are uncovered; when encountering a clay soil layer or a sand soil layer, the Luoyang shovel is adopted for manual exploration, and the exploration hole diameter of the Luoyang shovel is not smaller than the hole opening diameter of the drilling rig; when encountering miscellaneous fill or gravelly soil hard stratums, a flat-end steel chisel is adopted to drill, explore, crush and break down the fill or gravelly blocks; after the Luoyang shovel and the drill rod detection hole are completed at each frequency, a drilling bit rotation or percussion drilling method is adopted to clean the hole, the hole cleaning depth does not exceed the depth of the Luoyang shovel or the drill rod detection hole, the hole detection depth is measured before each time of hole cleaning, and meanwhile the corresponding depth position of a drill rod is marked before downward drilling; according to the stratum condition encountered during hole exploration, the operation is cyclically implemented until the known underground pipeline (channel) penetrates through the maximum burial depth, and hole exploration is completed; and if encountering an underground pipeline (channel), the drilling rig moves to perform hole exploration again.

Description

technical field

[0001] The invention belongs to the technical field of engineering survey and prospecting, and relates to a composite drilling method combining drilling, Luoyang shovel and brazing. Background technique

[0002] When carrying out engineering survey and exploration construction on complex strata such as municipal roads (including sidewalks and green belts) and filling areas with complex distribution of underground pipelines and pipelines, due to the complex distribution of underground pipelines and pipelines, there are electricity, telecommunications, heat, communication, water supply, Rainwater, etc.; there are many kinds of pipeline (road) materials, including steel, ductile iron, concrete, PVC, etc., and due to various reasons, the accurate burial data of underground pipelines and pipelines are lacking, and it is necessary to avoid various underground pipelines and pipelines for exploration, resulting in Engineering exploration is extremely difficult, and a...
