Static penetrometer ground anchor

Abstract

The invention relates to the field of geological survey equipment, and provides a static penetrometer ground anchor. The static penetrometer ground anchor comprising an anchor rod and an anchor head disposed at one end of the anchor rod, the anchor head is in a tapered shape, and the anchor rod is of a hollow structure. The static penetrometer ground anchor further comprises a rotating shaft and reeds, the rotating shaft is rotatably mounted on the anchor rod through a hollow structure, the reeds comprise root parts and end parts, the root parts of the reeds are mounted on the rotating shaft, through holes are formed in the positions, corresponding to the end parts of the reeds, of the anchor rod, and the through holes are used for extending out the reed into a soil body. According to the static penetrometer ground anchor, a ground anchor of a retractable anchoring structure is formed through the rotating shaft, the reeds and the through holes arranged corresponding to the anchor rod, the installation and removal process is simple, the anchoring ability is high, the damage to the soil body when the ground anchor is screwed into the soil body is reduced, and the workload and labor intensity of static cone penetration tests are reduced.

Description

technical field [0001] The invention relates to the field of geological survey equipment, in particular to a ground anchor for a static penetration sounder. Background technique [0002] Static CPT refers to using a pressure device to press a penetrating rod with a contact probe into the test soil layer, and to test the penetration resistance of the soil layer such as cone tip resistance and side wall friction resistance through the measurement system to determine certain properties of the soil. Basic physical and mechanical properties, such as soil deformation modulus, soil allowable bearing capacity, etc. As a device for static penetration testing of foundation soil, the static penetration sounder is widely used in construction, water conservancy, electric power and other fields. The static penetrometer can use three forms of ground anchor, weight or vehicle self-weight to generate reaction force during the test. Among them, the device using the ground anchor as the reac...

Problems solved by technology

[0004] An embodiment of the present invention provides a ground anchor for a static penetrating sounder, which is used to solve the problem that the existing ground anchor is not easy to screw into the stratum, which takes time and effort, and disturbs the original soil layer, so that the soil where the ground anchor is located becomes loose, reducing the cost. The problem of the anchoring effect of the ground anchor
