Since the industrial revolution, the development process of human social civilisation has changed rapidly. While people have enjoyed the fruitfulness of the industrial revolution, the ecological environment has suffered damage, and with the development of society, people have not only put forward higher requirements for material and cultural life, but also for the environment and other aspects. Therefore, it is particularly important to carry out environmental sampling by means of an environmental sampling rig to determine the physical-chemical and ecosystem indicators in the environment in order to determine the state of environmental pollution or the level of environmental quality.
After China entered the 21st century, the trend of relocation of industrial parks originally built in the inner city accelerated, and the original sites were transformed into commercial or residential sites. Environmental sampling and restoration integrated machine, independent research and development of adaptive load matching hydraulic system, can provide the required hydraulic pressure and flow according to the load feedback, so that the direct push environmental sampling drilling rig at the same time has sufficient power, low energy consumption, high efficiency, long life characteristics. Specifically, environmental sampling rigs should include the following.
The entire rig should be of a reasonable and compact design. In addition to reliable, good quality key components such as engines, hydraulic pumps, hydraulic motors and powerheads, matching hydraulic regulation and oil circuit systems are required to ensure coordinated working of the entire rig assembly. The rig should have an adaptive load matching hydraulic system that provides the required hydraulic pressure and flow according to load feedback. Under light vehicle load or no operating conditions, the system pressure is automatically reduced, greatly reducing hydraulic oil heat generation and engine load; when operating at higher ambient temperatures and performing high duty cycle operations, the pressure and flow of the regulating system is consistent with the load, which will result in significant fuel savings, while reducing hydraulic system components and extend service life.
It should be adaptable to difficult site working conditions and the rig should have reasonable front and rear weight distribution and be equipped with power supplied by a bespoke construction machinery chassis and hydraulic system. The climbing angle should be at least 30 and should have good passability to suit the requirements of certain slopes, soft soils and construction debris on complex sites. At the same time, the rig working unit should be able to perform forward and backward, left and right, tilt and pendulum movements to improve accessibility to the operating point and be fine-tuned to the actual operating point to ensure vertical operation.
It should be highly stratigraphically adaptable and capable of drilling and sampling in sedimentary, sand, pebble and hard formations, which requires a direct push drill rig with a variety of drill bits and corresponding drilling tools and drilling techniques in addition to strong power to achieve a competent core adoption rate. in different strata.
