Rock bolting has great supporting effect and ensures project’s security and long-term stability

Rock bolting  has great supporting effect and ensures project’s security and long-term stability.The self drilling rock bolt is unique anchoring system and fulfills current and increasing demands of the tunneling industry and ground engineering for safer and faster production. Sinorock self drilling rock bolt  is a reliable and convenient anchoring system which is applied in complicated geological conditions for rock support work. It is particularly applied in the following geological conditions, such as weathered rock, gravel layer, backfill, hard conglomerate, etc. The self drilling rock bolt system provides advantages for all areas of its applications, where boreholes would require the time consuming drilling with casing systems in unconsolidated or cohesive soil.

Adopting self drilling rock bolt to reinforce water-conveying tunnel is the application of geotechnical engineering technology in the aspect of tunnel project, which transmits structures’ tension by using surrounding rocks’ shearing strength or keeps self-stability of excavation face.

The Sinorock self drilling anchor system is today’s solution for a fast and efficient anchoring system into virtually any type of soil.The system has historically been known as a “self drilling anchor bar” because the hollow fully-threaded bar serves as both the drill string and the grouted anchor, thus installation is performed in a single operation.

The thread form (similar for all diameters)of our hollow anchor bar is a unique feature that provides a lower thread pitch angle to provide easier coupling disengagement without “locking up”, than conventional rope threads during drilling operations.This thread form provides more surface area and thread/deformations per unit length for superior bond capabilities over that of competitive drill steel thread forms.

Self drilling anchor bolt is a flexible shoring system

Urban deep foundation excavations are generally surrounded with dense buildings. So their working space is very narrow, especially when they are close to the foundations of adjacent buildings or structures in construction. Many scholars, engineers and technicians have already worked a lot in the displacement-controlling design of deep foundation excavations recent years, however, difficulty remains to be solved in correlation among the retaining structures, soil deformation around the excavations and the displacements of adjacent structures.
Self drilling anchor bolt is a flexible shoring system and is constructed from top to the bottom in steps parallel to excavation.The main elements of the system are self drilling anchors, reinforced shotcrete surface cover and subhorizontal drains.The length and spacing of the self drilling anchors are variable depending on the depth of the excavation, environmental loads and soil conditions, etc.
In this self drilling anchor system, depending on the ground conditions after each excavation stage pre-shotconcrete is applied, followed by passive anchor drilling. Appropriate reinforcement is placed into the drill holes according to the design and the drill hole around the reinforcement is grouted with cement grout.

Self drilling anchor is mainly used for slope stabilization, foundation with micropiles

The technical characteristics of self drilling anchor system: its main part is a hollow bolt which can act as a drilling and grouting pipe together. Before grouting, the dust can also be blown after drilling; the hollow bolt can act as grouting channel, and the cement slurry eject through the drill bits, which makes self drilling anchor bonded tightly to the soil around. Hence, the purpose of reinforcing rock will be achieved finally.

Before drilling, the shank of the link rod is connected to the self drilling anchor and the drilling machine. With the bore rock drilled to the design depth, install the plate and nut, and the next progress is grouting. The size of the drill bits can control the size of the drilling holes. Generally speaking, the diameter of the drilling holes is about 2-3 times of the size of the drill bits. Because its rod can be cut freely, the self drilling anchor can not only be applied for railways, tunnels, slope reinforcement and other projects, and it is more suitable for ground subsidence, governance hole collapse, landslides and other geological disasters.

As an efficient anchoring method, self drilling anchor is mainly used for slope stabilization, foundation with micropiles and tunneling, it’s also widely used in the railway system, metro project, etc. It can be installed in sites with weak rocks, loose soil, weathered layer, sand with stone layer and so difficult to create a hole in complex formation. The unconsolidated ground condition favor the self drilling anchor bar technique for fast and simple method of installed compared to the traditional method. In modern tunnelling, especially in subsidence-sensitive or urban areas, the usage of self-drilling pipe umbrella support is a widely and successfully adapted spacious pre-support system.
