Long Auger Drill Machine Foreground Market Analysis
Long auger drilling machine is mainly used for industrial and civil construction, electricity, transportation and other construction of the foundation of the pile hole construction, but also for underground construction of the continuous wall. CFG32 long auger drilling, drilling for the straight hole, that is, into a pile for the straight hole. Auger rig with no vibration, no pollution, low noise, high efficiency and can avoid the characteristics of a large number of earth transport, therefore, especially for urban or narrow site construction of the basic construction. Changing the type of drill bit allows the drilling machine to drill permafrost, concrete, lime and rock; change the speed of the drilling machine, so that the drilling machine in the water content is high and even saturated soil drilling into the hole. The rig is ideal for mechanized foundation construction.
Long auger drilling machine because of its installed power, the output torque, axial pressure, flexible, high construction efficiency, environmental protection and other characteristics, with different drilling tools to adapt to most of China's geological conditions, become suitable for building Works in the hole into the best construction machinery. In recent years, Beijing Metro, the construction of road network, especially the Qinghai-Tibet Railway, the Olympic venues, the new airport terminal and other large projects in the construction of rotary drilling rig efficient, environmentally friendly, high efficiency has been recognized.
With the gradual deepening of reform and opening up, the domestic market economy needs, making the railway highway waterway traffic, urban public facilities and industrial civil construction, water conservancy and power facilities, port terminal airport construction of the rapid development of pile foundation construction machinery potential huge market has emerged The Only railway construction, in 2005 China will be on a number of new projects, by 2020 the total investment in railway construction to more than 2 trillion yuan. This year there will be several high-speed passenger line, such as Wu Da, Zhengxi, Shi Tai, Beijing and Tianjin have started, high-speed passenger line more than 60% for the bridge, the bridge pile diameter mostly suitable for rotary drilling rig construction, which will be following the Qinghai-Tibet Railway After the rotary drilling rigs have more large-scale applications in railway construction.
Long auger drilling machine and construction technology in the northern region of China has been very popular in the southern region, especially in the southeastern coastal developed areas due to the formation of soft, the pile is generally deep and deep, rotary drilling rig into the hole difficult, Positive and negative circulation drilling machine. In fact, the rotary drilling rig with some other equipment can also be in the area of construction, one method is rotary drilling rig and casing drilling rig joint construction; another method is the use of China has been widely used vibration pile hammer drill steel tube In the soft soil area into the hole construction.
Long auger drilling machine is a large number of applications only in recent years, we lack the corresponding product standards, has not yet compiled rotary drilling rig construction specifications, no systematic engineering research, the lack of technical training, the basic theory of research to be in-depth, long auger Machine and civil engineering and construction technology is very close. Development of long auger drilling machine design and technical personnel should be familiar with the pile foundation construction, the use of long auger drilling engineering and technical personnel should understand its working principle and operating performance, for which the China Construction Machinery Industry Association and the relevant scientific research units, Manufacturers and construction departments to carry out and rotary drilling rig related to the basic structure of the working principle, hydraulic technology, mechanical and electrical control technology, safety procedures, etc.) technical training, construction experience and other activities, timely development of rotary drilling rig product standards and related standards , To promote the development of mechanized construction and rotary drilling rig products.
