Problems solved by technology

[0003] However, due to the wide variety of soils, the existing rock soil sampling devices cannot meet the requirements of different types of soil layers, especially the soil layers are often mixed with hard rocks, so that the existing rock soil sampling devices can only get the soil surface. sample, unable to penetrate into the soil for sampling, resulting in inaccurate analysis of the soil layer, and ultimately causing serious safety hazards to the safety of buildings and their foundations

Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help understand the present invention, but are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.

[0023] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by on...

Abstract

The invention relates to the technical field of rock-soil sampling. The invention discloses a rock-soil sampling mechanical device for civil engineering. The device comprises a sampling needle; a drill bit is arranged at the bottom of the sampling needle; the sampling needle is detachably connected with the drill bit; the outer wall of the sampling needle is sleeved with a telescopic part; a balancing weight is arranged at the top of the sampling needle, and the balancing weight is fixedly connected with the sampling needle; a sampling groove is formed in the outer wall of the sampling needle,the sampling groove is a spiral sampling groove, and the lower portion of the sampling groove extends to the outer wall of the drill bit; and the outer wall of the sampling needle is sleeved with a supporting frame, the lower portion of the supporting frame is detachably connected with a sampling plate, and a driving device is installed on the supporting frame. The technical problem that an existing rock-soil sampling device cannot meet different soil texture requirements and is low in sampling efficiency and short in service life is solved.

Description

technical field [0001] The invention relates to the technical field of rock and soil sampling technology, in particular to a rock and soil sampling mechanical device for civil engineering. Background technique [0002] Geotechnical test is an important part of engineering geological survey. Through rock and soil sampling test, the foundation bearing capacity of different types of soil can be determined, the shear strength of cohesive soil and sandy soil can be estimated, and the compression deformation index of cohesive soil can be judged. The state of consistency and the compactness of the sand and the possibility of vibration liquefaction. The information obtained after the soil sampling test during the survey is the basis for subsequent engineering design, construction and other work. Only by knowing the soil quality can we understand the type of foundation and the method of foundation treatment, and can accurately design engineering drawings. It is also possible to make...
