Problems solved by technology
[0003] During the use of the existing foundation testing and sampling equipment, due to the long sampling depth, multi-section sampling pipes need to be connected. The traditional connection method is threaded connection. This connection method is not only time-consuming and laborious, but also has low installation efficiency. , it is not convenient for the staff to install and disassemble. At the same time, when sampling and recovering, the opening at the bottom will easily cause the sampled soil to fall under gravity, which will affect the sampling results. Therefore, we propose a foundation detection sampling equipment and sampling method for water conservancy projects to solve the above problems.

The invention discloses foundation detection sampling equipment for the water conservancy project comprises a bottom pipe, a pressing pipe is fixedly arranged at the bottom of the bottom pipe, a connecting block is fixedly arranged on the inner side wall of the pressing pipe, and a rotating rod is movably arranged on the connecting block; an elastic opening and closing plate capable of controlling opening and closing of the bottom of the downward pressing pipe is fixedly arranged on the outer side wall of the rotating rod, and a sliding groove is formed in the inner side wall of the downward pressing pipe. According to the equipment, in the descending process of the sampling pipe, the bottom pipe descends, then the pressing pipe descends, and at the moment, the soil jacks open an elastic opening and closing plate, soil can enter a sampling pipe, an elastic opening and closing plate can push a transmission threaded rod towards the two sides, a transmission roller rotates, a transmission gear rotates through transmission of a conveying belt, then a gear ring rotates, when the gear ring rotates, a downward pressing threaded rod descends, a downward pressing block is pushed out, soil breaking work is conducted, and the soil breaking efficiency is improved; and the sampling work is facilitated.
Description
technical field [0001] The invention relates to the technical field of foundation sampling, in particular to a foundation detection and sampling device for water conservancy projects and a sampling method thereof. Background technique [0002] The geological conditions at the foundation of a water conservancy project have a decisive impact on the construction, quality and durability of the foundation after construction. Before the design and construction of a water conservancy project, it is necessary to sample and test the soil samples at the site of the water conservancy project, and then according to the test results After a comprehensive comparison, the location of the hydraulic engineering foundation is determined. [0003] During the use of the existing foundation testing and sampling equipment, due to the long sampling depth, it is necessary to connect multi-section sampling pipes. The traditional connection method is screw connection. This connection method is not on...
