"Rotary Drilling Method for the Construction General Statutes," the preamble
Recent years, with auger drill in various engineering applications continue to spread, the number of rotary drilling rigs and production also showed a rapid increasing trend of manufacturers, which is the basis of construction machinery industry to promote technological progress, needs and mitigation projects the contradiction between the supply of equipment, no doubt a comforting thing. However, in our country, both rotary drilling rig manufacturers, or users, its practice is still very short of time, experience and the accumulation is still limited. Meanwhile, as the user base for the gradual expansion of new entrants, they have been Zeng Jia, an urgent need to develop and introduce appropriate Zhuanmen construction procedures, Lai Zhi Dao and regulate the Rotary Rig The Gegehuanjie. The development of national or industry standards, require a lot of engineering data as support, also take longer to research. This resulted in the construction of an objective standard on the lag.
Fortunately, Beijing 31 Heavy Machinery Co., Ltd. as a rotary drilling rig manufacturing business, but always construction and so on engineering research and practice on the important position of the business, and therefore made a good performance. This "rotary drilling rig construction method common point of order" than the professional standards, there may be insufficient and this or that flaw, but it can certainly help customers rotary drilling rig, especially new entrants, the construction method find more accurate and effective way.
This is a good start, hope to rotary drilling rigs and other infrastructure construction machinery and strengthen project design, construction and equipment industries and enterprises between the exchange and interaction, foundation engineering and equipment to promote technological progress .
