Description
Technical Field
The invention relates to a direct-push type sampling device integrating multiple drill bits, and belongs to the technical field of engineering machinery.
Background
The soil is strong in heterogeneity and hidden, and a representative soil sample can be obtained by adopting a proper drilling measure for analyzing the soil property of the land parcel. The soil samples for environmental investigation are required to be non-disturbed in technical guidelines such as a technical guideline for managing and controlling risk of soil pollution in construction sites and monitoring technology (HJ 25.2-2019), a technical guideline for soil sampling for soil quality (GB/T36197-2018), and technical regulations for collecting, storing and circulating survey samples for sites of enterprises in key industries.
The SH30 type drilling machine in China generally uses mechanical power and a steel rope to repeatedly lift and drop a hammer head within a certain range so as to provide impact force for drilling and soil undisturbed sampling. The rig uses a mobile rig consisting of a diesel engine driven winch (1t-2t) and an approximately 6m high triangular tower. The steel cable percussion drill is cheap and has certain maneuverability, and can drill and sample in most fields and obtain continuous and undisturbed soil samples on the premise of correct operation. However, the technology has single function (drilling process and matched tools), complex sampling operation and low efficiency, generates more cutting float soil, increases the risks of secondary pollution and operators, and increases the construction period and the cost of the whole sampling.
The direct propelling type drilling technology is that a drilling tool is directly penetrated into soil for sampling by utilizing the self gravity of a drilling machine and the impact force (hydraulic drive) of an external knocking hammer. The direct propulsion type drilling system has lower disturbance than the steel cable impact drilling system; the maneuverability is strong and the operation is simple; the drilling rate is about 5-10 times of that of the wire rope impact method; meanwhile, no floating soil is generated in the drilling process, so that the risks of secondary pollution and operators are reduced, and the extra cost of treating and polluting the floating soil is avoided; in particular, MC5 drilling can be used to sample fine sand formations, while wire rope impact methods do not allow for efficient sampling of sand and miscellaneous formations; in addition, the direct push type drilling is matched with a large number of drilling tools and drilling processes, switching can be performed according to different stratums and pollutants, and the matched in-situ detection tool can realize in-situ, real-time and continuous measurement while drilling on the stratum properties and the pollution conditions of the polluted soil, so that the pertinence and the efficiency of the polluted land survey are greatly improved. However, due to the limited gravity of the drilling machine and the limited impact force of the impact bit, it is difficult to effectively complete the sampling work in some complicated or hard ground layers.
