Problems solved by technology

In reality, the cross-plate shearing instrument on the ground or on the platform applies torque to one end of the drill pipe and transmits it to the distal cross-plate head, which will cause elastic deformation such as bending or twisting, as well as partial friction between the drill pipe and the hole wall. The deeper the drill pipe is, the longer the drill pipe is, the greater the elastic deformation will be, resulting in the distortion of the cross plate test data obtained
The latter makes full use of boreholes and uses the in-situ soil shear method to obtain the natural strength index of the soil, but cannot simultaneously obtain physical indexes such as water content, void ratio, and pore water pressure of the soil.

Abstract

The invention discloses an integrated device for cross plate testing and sampling and a use method. The device comprises the following components: a drum, a lifting motor, a screw rod, a torsion motor, a cross plate head and a sampling tube, wherein the upper end of the drum is connected with a drilling rod; the lifting motor is fixedly arranged in the drum; the screw rod is connected with the lifting motor and is matched with a nut fixed in the drum; the torsion motor is connected with the lower end of the screw rod; the cross plate head is connected with the torsion motor through a shaft rod; the sampling tube is detachably arranged at the lower end of the drum. According to the invention, the undisturbed sample can be acquired, the onsite cross plate test also can be completed, the porewater pressure of natural soil even can be measured, the multifunction of a drill bit can be achieved and the purpose of reducing the exploring cost is achieved. According to the invention, the lifting motor and the torsion motor are arranged in the drum at the lower end of the drilling rod and the cross plate head is connected nearby, so that a more real shear strength value of natural soil canbe acquired.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering exploration, in particular to an integrated device for cross-plate testing and sampling. Pressure value. Background technique [0002] In engineering geological exploration, in order to obtain the physical and mechanical indexes of soil, at present, it mainly depends on drilling and sampling laboratory tests. However, when sampling, there is friction between the soil sample and the inner wall of the sampling cylinder; during the indoor test, the bulldozing process will cause friction between the soil sample and the sampling cylinder again, so that the stress is relaxed and then compressed, resulting in distortion of the obtained mechanical strength index. The cross plate shear test is to apply torsion on the spot through the cross plate head inserted into the soil, so that the cross plate head is twisted at a constant speed in the soil until the soil is sheared, and the maximum t...
