Example Embodiment

[0041] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0042] An engineering geological survey device, such as figure 1 , 2 As shown, it includes a drill pipe 1, a handle 2 fixed on the upper part of the drill pipe 1, and a drill bit 3 fixed on the lower part of the drill pipe 1. The drill bit 3 is provided with a sampling device 4, and the sampling device 4 performs sampling operations of different soil layers.

[0043] like figure 1 , 2 As shown, the sampling device 4 includes a control rod 5 and a sampling tube 6, the sampling tube 6 is movably connected in the drill bit 3 in the vertical direction, and the control rod 5 is rotatably connected to the upper part of the sampling tube 6 and passed through the outside of the drill rod 1, so as to facilitate The control rod 5 is controlled from the outside to complete the sampling operation of different collection grooves 61 on the sampling tube 6 .

Abstract

The invention relates to the technical field of geological exploration, and discloses an engineering geological exploration device. The engineering geological exploration device comprises a drill stem, a handle fixed to the upper portion of the drill stem and a drill bit fixed to the lower portion of the drill stem, wherein a sampling device is arranged in the drill bit, the sampling device comprises a sampling pipe which is movably connected in the drill bit through a movable structure, at least two collecting grooves are formed in the sampling pipe, feeding inlets are formed in the side wallof the drill bit, and the collecting grooves can correspond to the feeding inlets. The engineering geological exploration device has the following advantages and effects that at least two collectinggrooves are formed in the sampling pipe in the drill bit, and when the drilling depth of the drill bit is changed, collecting of soil samples at different soil layers can be conveniently achieved by corresponding the different collecting grooves to the feeding inlets. Therefore, the cumbersome steps that after drilling sampling is conducted, the drill bit is pulled out for discharging, and then drilling sampling is conducted again are not needed, and operation is easy and convenient to achieve; and thus, improving of the exploration accuracy is facilitated by means of sampling comparison of different soil layers.

Description

technical field [0001] The invention relates to the technical field of geological prospecting, in particular to an engineering geological prospecting device and its usage method. Background technique [0002] Geological prospecting is the abbreviation of geological prospecting work. In a broad sense, it can generally be understood as a synonym for geological work. It is based on the needs of economic construction, national defense construction and scientific and technological development. According to different purposes, there are different geological exploration work. [0003] At present, when carrying out geological exploration work, it is generally necessary to sample and observe the soil layers in a certain area, and in order to improve the accuracy of the sample research, it is usually necessary to sample the soil of different layers. However, the existing sampling devices only A single sampling can be carried out, but in order to ensure the accuracy of the survey, the...
