Deep-stratum in-situ penetrometer, penetration sounding trolley comprising the same and using method thereof

Abstract

The invention discloses a deep-stratum in-situ penetrometer which can carry out continuous, quick and accurate measuring on a hard, thick and deep stratum. The penetrometer comprises a diesel engine, a hydraulic pump station, a water pump, a water tank, an operation control disc, a drilling rig, a power head, sensors, a drill bit drill rod, a moving conveying frame, a data collecting and storing system and a data processing system. The diesel engine and the hydraulic pump station are connected with the power head. The water pump and the water tank are used for cooling the drill bit drill rod. The operation control disc is used for controlling the depth of a drill bit drilled into a stratum. The sensors comprise a torque sensor, a propulsive force sensor and a displacement sensor. The sensors transmit torque data, propulsive force data and drilling speed data to the data collecting and storing system. The data processing system receive the data of the data collecting and storing system for processing. A penetration sounding trolley and a using method of the deep-stratum in-situ penetrometer and the penetration sounding trolley are further provided.

Description

technical field [0001] The invention belongs to the technical field of in-situ testing of geotechnical engineering, and in particular relates to an in-situ penetrating instrument for deep formations, a penetrating vehicle containing it, and a method for using the two. Background technique [0002] The in-situ testing of geotechnical engineering is mainly drilling and penetration testing. Conventional penetration testing is difficult to penetrate dense silt and sandy soil layers with a buried depth of more than 35m. The physical and mechanical indicators of deep soil layers are mainly obtained by drilling sampling and standard penetration. However, the existing exploration methods can no longer meet the requirements of high precision, fast speed and no disturbance of engineering construction. Seeking continuous, rapid, accurate, and undisturbed technologies that can be applied to harder and deeper formations is a new direction for the development of geotechnical engineering i...
