SDP Series Static Drill Root Method

576a27c8eceaa.jpg

The SDP series of static drilling root-planting rigs is a new generation of drilling rigs that Shanggong Machinery takes advantage of the research and development of deep mixing rigs accumulated over many years to develop completely independently. The main parts of this product are from internationally renowned brands, with high torque, deep drilling depth, high technology content, good reliability, high construction efficiency, etc., and the performance reaches the international advanced level.

Compared with the traditional construction methods such as hammered piles, static pressure piles and cast-in-place piles, the static drilling and planting method has the characteristics of no vibration, no squeezing, low noise, good pile formation quality, high bearing capacity of single pile, and less mud discharge. It can meet the requirements of urban construction. It is a new environmentally friendly, energy-saving and efficient construction process. It has been widely used in Japan, South Korea and Taiwan and other countries and regions. Introduced to China in recent years, first applied in Zhejiang Province, with good results.


Overview

  • New pile foundation construction method using root-implanted pile combination

  • Drilling + bottom expansion + deep mixing + planting piles

  • Adapt to pile diameter: 500-1200mm

  • Maximum penetration depth: 90m

 

special point

  • 1. No compaction, no vibration, low noise

  • 2. The pile forming quality is good, and the height of the pile top is completely controllable

  • 3.Extremely strong vertical compression, anti-pull and anti-horizontal load capacity, less mud discharge

  • 4. Has good social benefits and promotion value

粘性土、粉土、砂土、填土、碎(砾)石土以及地质情况复杂、夹层多、风化不均、软硬变化较大的岩层 5. It is suitable for various seismic fortification intensity areas: cohesive soil, silt soil, sandy soil, filling soil, crushed (gravel) stone soil and complex geological conditions, many interlayers, uneven weathering, and large changes in soft and hard

  • 桩端持力层层顶标高变化较大,桩的长度难于准确确定时施工场地不具备混凝土现场浇注条件或者是现场浇注混凝土质量不容易保证的工程 6. When the construction site is close to engineering facilities such as buildings (structures) or underground pipelines, the use of other pile types will cause adverse effects when the top elevation of the pile end holding layer changes greatly, and the length of the pile is difficult to determine accurately Projects with on-site concrete pouring conditions or difficult to guarantee the quality of on-site pouring concrete

  • 7. Projects with restrictions on large amount of mud discharge

  • 8. When the design requires a single pile with a large bearing capacity and technical and economic indicators and construction conditions are superior to other pile types
