Introduction to static drilling rooting method
Construction method features:
●No soil squeezing, no vibration, low noise;
●The pile quality is good and the pile top elevation is completely controllable;
●Extremely strong vertical compression, pullout and horizontal load resistance capabilities;
●Less mud emissions;
●Has good social benefits and promotion value.
Scope of application:
●Suitable for areas with various seismic fortification intensity, applicable pile diameter: 500-1200mm;
●Cohesive soil, silt, sandy soil, fill soil, crushed (gravel) stone soil, and rock formations with complex geological conditions, many interlayers, uneven weathering, and large changes in softness and hardness, the maximum depth of soil penetration: 90m;
When the construction site is adjacent to buildings (structures) or underground pipelines and other engineering facilities, using other pile types will cause adverse effects;
●The elevation of the top of the pile end bearing layer changes greatly and the length of the pile is difficult to accurately determine, the construction site does not have the conditions for on-site concrete pouring or the quality of on-site concrete pouring is not easy to guarantee;
●Projects with restrictions on the discharge of large amounts of mud;
●When the design requires a single pile to have a large bearing capacity, and the technical and economic indicators and construction conditions are superior to other pile types.
Advantages of static drilling rooted piles
Static drilling and rooting piles use low-noise drilling rigs (static drilling) and burying methods to complete prefabricated piles (pile planting). It is the master of modern pile foundation technology. After years of promotion and application, its significant advantages of "more, faster, better and more economical" such as green environmental protection, energy saving and emission reduction have been highly recognized by all sectors of society.
Construction method features:
●By adopting various pile type combinations such as bamboo piles and composite reinforced piles, as well as bottom expansion and grouting technologies, the pile foundation's compression, pullout and horizontal bearing capacity can be greatly improved;
●Suitable for a variety of geological conditions, especially pile foundations with high bearing and high load requirements.
●High construction efficiency, a single machine can drive more than 300 meters of piles in a single day, and the economic benefits are higher than other pile types;
●Through the drilling rig current, changes in the bearing layer can be detected without pile cutting;
●A simple, fast, and reliable mechanical connection method can be selected to ensure the reliability of pile connection and the efficiency of construction.
1. The pile materials are factory-prefabricated and the quality is guaranteed;
2. Construction using the buried method, no soil squeezing, and no damage to the pile body;
3. Intelligent construction and fully automatic monitoring of equipment to ensure construction quality;
4. The pile body and pile joints are protected by cement and soil to improve corrosion resistance;
5. Green and environmentally friendly, it fundamentally solves the problem of mud emissions during engineering construction.
Compared with bored piles under the same conditions:
1. Water saving (90% water saving in construction);
2. Energy saving (construction energy consumption saved 40%);
3. Emission reduction (slurry emissions reduced by 70%);
4. Time saving (construction efficiency increased by 50%);
5. Cost saving (project cost saving 10%-20%);
6. Carbon emissions are reduced by more than 50%.
