Hydraulic Engineering Percussion Drilling Rig
Percussion drilling is a manual drilling technique in which a heavy cutting or hammering bit attached to a rope or cable is lowered in the open hole or inside a temporary casing. The technique is often also referred to as 'Cable tool'. Usually a tripod is used to support the tools. By moving the rope or cable up and down, the cutting or hammering bit loosens the soil or consolidated rock in the borehole, which is then extracted later by using a bailer. Just as with hand augering, a temporary casing of steel or plastic may be used to prevent the hole from collapsing. When the permanent well screen and casing are installed, this temporary casing has to be removed.
The percussion borehole drilling rig's technical advantages:
- Unlike any other drilling method, percussion can remove boulders and break harder formations, effectively and quickly through most types of earth.

China's micro-small fasteners dispersed and low value-added products, excess production capacity, and many companies dumped at low prices, the market is not standardized, the competitiveness of enterprises is not strong. Specialization, specialization, and refinement are the roads we need to take.
Old and old products should choose to abandon old Xihua (Guangdong Fastener Industry Association president)
Enterprises should open up the inertial thinking of “many products and good managementâ€. They should optimize their own product structure, and do products that they are proficient in and can enhance their intrinsic value through their own efforts. At the same time, they should follow the domestic fastener industry. Industrial trends to optimize, old and old, no much profit margins of the product on the timely choice to abandon.
Transformation and Upgrading Needs to Be Costed Li Yiping (Professor of Economics, Renmin University of China)
There is a misunderstanding that the way companies transform their development is on high-tech projects. Of course, today's projects must have higher technological content than previous projects, but if they still do not include costs, do not compare inputs and outputs, do not talk about economic efficiency, and do not follow basic economic laws, they will still be excessively prosperous. Operating.
Transformation and upgrading can not lose the "old home"
Zhu Changlin (Director of Management Committee of Zhejiang Yongkang Economic Development Zone)
To innovate in transformation and innovation, we must not lose our old business. Taking Yongkang as an example, the foundation of manufacturing and sales for decades has laid the foundation for the current status of “Science & Technology Hardware Cityâ€. We can't go all out and lose the existing strong industrial foundation and build a market to talk about transformation and upgrading.
The key to technological innovation is Liu Yingqiu (Dean and Professor of Graduate School of Chinese Academy of Social Sciences)
For enterprises to achieve greater development, they must first choose technological innovation. Technically, it is beyond reproach, and it is also feasible. However, the cost it has brought has risen sharply. The reality has forced companies to prefer technological innovation. More importantly, through technological innovation, the quality and efficiency of the company's stock capital can be improved, which is the best way for the company to achieve greater development.
Individual differences should be considered in transformation and upgrading Cao Rongqing (Director, Institute of Economic Research, Zhejiang Normal University)
When one mentions the transformation and upgrading, many people think of doing high technology. In fact, this is a misunderstanding. Enterprises can't compare their weaknesses with other people's strengths, and they must consider individual differences in transformation and upgrading. The more important task of an enterprise is to strengthen its existing core competitiveness rather than blindly engage in transformation and upgrading.
- Percussion drilling can in principle deal with most ground conditions.
- Can drill hundreds of feet (one well hand-drilled in China in 1923 was over 4000 feet deep).
- Can drill further into the water table than dug wells, even drilling past one water table to reach another.
I visited two Korean factories. One company has more than 200 employees. Its sales are 600 million yuan, which means that the labor productivity per capita is 2 million yuan. In addition, more than 300 employees of more than one company created more than 1 billion yuan. The sales amount means 2.5 million yuan in labor productivity per capita. Almost all of the workshop is automated production.
