The survey aims to understand the nature and characteristics of underground rock and soil layers, and provide the necessary basis for engineering design, construction and supervision. Geotechnical engineering survey plays an important role in civil engineering, and its results directly affect the safety, economy and feasibility of the project. Through geotechnical engineering survey, we can fully understand the underground rock and soil conditions, provide a scientific basis for engineering design and construction, and ensure the quality and safety of the project. When the user uses the measuring device for surveying, he needs to press the measuring device against the rock and soil surface by hand to keep the measuring device fully fit to the rock and soil surface. The measurement operation requires the cooperation of both hands to measure the degree, and the operation process is relatively troublesome. Therefore, the inventor proposes a rock and soil slope measuring device for geotechnical engineering survey. Utility Model Content

[0027] The geotechnical slope measuring device for geotechnical engineering investigation also includes: a fixed grab plate 9, which is fixedly mounted on the outer rod 1, and a lifting rod 8 is fixedly connected to the upper surface of the movable inner rod 2. The lifting rod 8 is vertically arranged, and a connecting block 10 is fixed at one end away from the movable inner rod 2. Bubble levels 7 are respectively arranged on the upper surface and side wall of the outer rod 1, and the bubble levels 7 are vertically distributed.

[0028] One end of the spring 12 away from the movable inner rod 2 is fixedly connected to the inner wall of the outer rod 1. A rotating shaft 13 is fixedly connected to the outer wall of one side of the movable head 6, and the rotating shaft 13 is rotatably connected to the inner wall of the outer rod 1.

[0029] The end of the movable head 6 away from the rotating shaft 13 is fixedly connected to the follower rod 4, which is cocentrically distributed with the rotating shaft 13. The follower rod 4 rotates and passes through the outer rod 1, and a pointer 5 is fixedly connected to the outer wall of the passing end. The angle plate 3 is fixedly installed on the side wall of the outer rod 1, and the pointer 5 corresponds to the angle plate 3.

[0030] Reference Figure 3 , Figure 4 A fixing block 11 is protruded from the outer wall of the connecting block 10, and a plug hole is provided on the fixing block 11.

[0031] When in use, the operator holds the fixed gripping plate 9 and the connecting block 10 with his hands. The connecting block 10 and the lifting rod 8 are distributed in a T shape. The lifting rod 8 can be placed between two fingers. When measurement is needed, the limit screw 15 is turned to make it spirally rotate along the fixed outer tube 14, and the end portion withdraws from the fixed block 11. After losing the limit, the spring 12 can pop out the movable inner rod 2 along the bottom of the outer rod 1.
