Introduction of construction method of rotary drill occlusal pile

Rotary drill is generally suitable for clay, silt, sand, silt soil, artificial backfill soil and the stratum containing some pebbles and gravel. For the drill with large torque power head and automatic internal lock type expansion drill pipe, it can adapt to the construction of breezy rock formation. In ORDER TO meet the construction requirements, the configuration of rotary rig chassis and working device has the characteristics of large installed power, large output torque, flexible, multi-function and high construction efficiency.

Introduction to the construction method of rotary digging and drilling occlusal pile

Working principle of the rotary digging drilling is to use the short spiral drill or rotary digging bucket, the use of powerful torque directly to the soil or gravel etc on the drill rotary digging, and then quickly hole is put forward, in the case of don't need slurry-supported, which can realize dry construction, even in the case of special stratum need slurry-supported, mud is also only a supporting role, in the drilling mud content is quite low, This greatly reduces the pollution source, reduces the construction cost, improves the construction environment, and high efficiency of hole formation.

Introduction of construction method of full casing occlusal pile

The full casing drilling bite pile belongs to the soft cutting mode, that is, before the initial setting of the first sequence pile (using ultra-slow concrete), the second sequence pile is constructed to cut the first sequence pile to achieve the bite. It IS A SPECIAL TYPE OF PILE WHICH MAKES USE OF THE SPECIAL PROPERTIES OF SUPER RETARDED CONCRETE AND ADOPTS THE WHOLE CASING DRILLING MACHINE TO FORM HOLES AND PILES ACCORDING TO the SPECIAL TECHNOLOGY. Through the interlocking and lashing between piles, it can form the continuous row pile enclosure structure or underground seepage prevention wall, which can keep soil and water, and has good waterproof and soil retaining performance.

Brief introduction of occlusal pile

Occluding pile is a kind of foundation pit row pile enclosure, the adjacent concrete row pile part of the circumference is embedded, reinforced concrete pile and plain concrete pile cutting and occluding, so as to form an integral continuous waterproof, retaining and retaining structure with good impermeability. Because it is characterized by the mutual occlusion between piles, it is called occluding pile.

Functional composition and classification of pile foundations

Pile foundation is one of the most widely used forms of deep foundation, which consists of a number of piles sunk in the soil and a cap or cover beam connecting the pile top. The role of pile foundation is to transfer the load of the upper building to the pile through the cap or cover beam, and then to the deep soil (rock) layer with strong bearing capacity, or the weak soil compaction to improve the bearing capacity and compactness of the foundation soil.

Survey points of foundation pit engineering

Compared with the investigation of buildings, the investigation of foundation pit engineering has its own characteristics. With the excavation of the soil inside and outside the foundation pit, there will be stratum movement. Therefore, there are specific requirements for the scope and depth of investigation and geotechnical index test items.
