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.

At present, the LED lighting era has been opened, and the competition is fierce, and the industry has entered the integrated reshuffle period. During this period, the competition between enterprises was not just about price, but also cost and more patents. Whoever has more patent atomic bombs, who can control the opportunities. To help LED enterprises to create high-end, atmospheric and high-grade patent layout, sponsored by the Patent Office of the State Intellectual Property Office, the Guangdong Semiconductor Lighting Industry Joint Center, the Guangdong Provincial Department of Science and Technology, and the Guangdong Provincial Intellectual Property Office, the LED Industry Patent Alliance The LED industry patent analysis seminar and patent analysis popularization project results presentation will be held in Zhudao Hotel on the afternoon of November 19.
It is reported that the State Intellectual Property Office organized a patent analysis popularization project during the 12th Five-Year Plan period. In the LED lighting industry, the patent analysis popularization and promotion project carried out the patent analysis of the LED lighting industry in 2013, and combined with industrial policy, technology, industry and other information to conduct in-depth analysis of domestic patents in the field of LED lighting, and related research work has been completed and formed. Many analysis results have important practical value for the majority of LED companies.
In order to expand the popularization and promotion effect and better promote the development of the LED lighting industry, it is planned to hold the LED industry patent analysis and patent analysis popularization project (LED) at the East Lake Hall on the second floor of the Bajiao Building, Zhudao Hotel, Guangzhou at 13:30 on November 19th. Industry) Results presentation, relevant research results will be released for the first time at this meeting.
- 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.
