Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0017] Such as figure 1 and 2 As shown, the present invention includes a cylinder 1, the cylinder 1 includes a cylinder top 2 and a cylinder bottom 3 provided with threads on the outer circumference, the cylinder 1 is hollow inside, and a rectangular mounting hole is opened laterally on the cylinder wall 5. The width of the installation hole 5 is smaller than the diameter of the cylinder body 1 . Two pin holes 8 are prov...

Abstract

The invention relates to the field of geological exploration, in particular to a static cone penetration test soil sampler comprising a cylinder with the top and bottom which are provided with screwed threads. The upper side of the wall of the cylinder is provided with an installation hole; a sampling cylinder component which is capable of overturning along the cylinder longitudinally is rotationally fixed in the installation hole; an elastic member contacting with the sampling cylinder component elastically is fixed into the corresponded position of the inner wall of the cylinder and sampling cylinder component. The static cone penetration test soil sampler is capable of sampling required soil samples during the static cone penetration test, workload of field exploration efficiency is improved significantly, the number of drilling is decreased appropriately, the operation time and cost are saved, and the accuracy and efficiency of the static cone penetration test are improved.

Description

technical field [0001] The invention relates to the field of geological survey, in particular to a static penetration exploration soil fetcher. Background technique [0002] In-situ test The static penetration test has been used in my country for more than 30 years. It uses the contact method to test the strength and deformation of the soil, and on the basis of establishing a regression relationship with a variety of conventional methods, it determines the various properties of the tested soil on the spot. The design parameters and indicators, such as bearing capacity, compressive modulus, soil state, etc., are simple, economical, and fast compared with drilling, but there are also certain defects, such as the inability to identify the color of the soil layer and the difficulty in accurately naming it. Soil type, determine the state, and for the same mechanical index (same penetration resistance value), but different types of soil (such as cohesive soil and sandy soil), it is ...
