Embodiment 1

[0031] see Figure 1-8 , this embodiment provides a shearing instrument for in-situ detection of loess holes, as shown in Figure 2, which is the overall structure diagram of the instrument for measuring soil shear strength. The structure of the soil shear strength measuring instrument in the loess pipeline is symmetrically distributed, mainly composed of three parts: the moving carrier, the shearing part and the airbag carrier.

[0032] Further, motion vector 4 such as image 3 Shown, mainly be made up of main body 7, wheel 8 and wheel support 9 of fixed cylinder, be connected by spring between every pair of wheel support 9, motion carrier 4 just possesses certain self-adaptability when motion like this.

[0033] Further, cut part 5 as Figure 4 As shown, it is mainly composed of feed bearing 11, rotary bearing 12, connecting rod 13 and cutter 14.

[0034] Further, feed bearing 12 such as Figure 5 As shown, it consists of an inner ring, an outer ring and rollers. The inne...

Abstract

The invention discloses an in-situ detection shearing device of a loess hole. The in-situ detection shearing device comprises a motion carrier, a shearing part and an air bag carrier, wherein the motor carrier drives the shearing part and the air bag carrier to climb a wall and walk, the loess shearing tool is borne by the shearing part, the shearing part is used for driving the shearing tool to rotate and cut after the motor carrier reaches a detection position, the air bag carrier is connected with the shearing part and comprises a main air bag carrier and a side air bag carrier, the main air bag carrier bears a main air bag and is used for solidifying hole soil, the side air bag carrier bears a side air bag, and the motion carrier and the side air bag are jointly used for measuring a shearing force. In the shearing force, in-situ measurement test of soil shear strength can be performed in a loess underground pipeline, and soil shear strength at different soil layer positions can beaccurately measured.

Description

technical field [0001] The invention belongs to the technical field of soil performance testing, and in particular relates to a shear instrument for in-situ detection of loess holes. Background technique [0002] The Loess Plateau is the only young plateau with the largest distribution area of ​​loess in my country and even the world, the most complete development of loess, and the only accumulation of loess. Moreover, loess itself is a special disaster-prone soil with significant catastrophe sensitivity, mainly manifested in strong water sensitivity, fragile structure, unique strength decay, complex deterioration process, and dynamic disturbance. sensitivity etc. In the Loess Plateau region of the west, especially in northern Shaanxi, Lanzhou, Qinghai and other places, a large number of major engineering projects have appeared, disturbing and destroying the mountain structure formed by the natural evolution of the Loess Plateau over tens of thousands of years, and easily c...
