Soil sampling device for water conservancy project foundation
The invention relates to the technical field of water conservancy project foundation construction, in particular to a soil sampling device for a water conservancy project foundation. The drill cylinder is provided with an annular containing groove, and the upper side of the containing groove is connected with two containing hole channels. A cutting rope is arranged in the containing groove, the outer end of the cutting rope is connected with a driving plug, the driving plug is movably arranged in the containing hole channel, the outer end of the containing hole channel is connected with a hydraulic assembly, the hydraulic assembly is used for driving the driving plug to move along the containing hole channel, and the outer side of the cutting rope is connected with fan-shaped supporting cloth; when the driving plug moves upwards along the containing hole channel, the cutting rope cuts a soil block in the drilling barrel, and meanwhile the cutting rope drives the supporting cloth to be folded at the bottom of the soil block to form a supporting layer. The bottom of a soil column in the drilling barrel is cut through the cutting rope, meanwhile, the supporting cloth is pulled out, the supporting cloth forms a supporting layer at the bottom of the soil column, the soil column can be conveniently and completely taken out upwards, the soil sampling efficiency can be effectively improved, and soil is prevented from falling back into a hole channel.
本发明涉及水利工程地基施工技术领域，具体地说就是一种水利工程地基用取土装置。钻筒设置有环形的容纳槽，容纳槽的上侧连接有两个容纳孔道；容纳槽内设置切割绳，切割绳的外端连接有驱动塞，驱动塞活动设置于容纳孔道内部，容纳孔道的外端连接有液压组件，液压组件用于驱动驱动塞沿容纳孔道移动，切割绳的外侧连接有扇形的支撑布；当驱动塞沿容纳孔道向上移动时，切割绳对钻筒内部的土块进行切割，同时切割绳带动支撑布收拢于土块的底部形成支撑层。通过切割绳对钻筒内部的土壤柱的底部进行切割，同时将支撑布向外拉出，使支撑布在土壤柱的底部形成支撑层，方便将土壤柱完全向上取出，能够有效提高取土效率，避免土壤回落到孔道内。
