SDA rock bolt grouting by rod hole in the body from the inside to outside, at the same time, the outside of the rock bolt which plus plate and plug, can effectively prevent slurry spillover, when necessary, also can undertake pressure grouting, make grout diffusion to the surrounding rock fracture, so the rod body around the SDA rock bolt can form a thick enough and uniform coating, significantly improve the durability of the rod body; And ordinary mortar anchor is often using technology of grouting first ,and then insert bar, this process is difficult to guarantee grouting full degree, therefore it is often hard to avoid phenomenon of the steel rod body naked, if the naked steel contact with the ground water will lead to bare steel reinforcement corrosion, thus reduce the durability of the SDA rock bolt.

Sinorock is a reliable hollow anchor bolt manufacturer in the market. Developed in accordance with set industrial norms, Sinorock SDA rock bolt is severely checked and perfect on all quality parameters. Our extensive ranges of rock bolts are designed carefully by our experienced engineers who have a sound knowledge about these components. Our collection of goods includes of R thread anchor system, T thread anchor system, anticorrosion rock bolt, rock drill, etc. 

The hollow anchor bar structure must have a good ductility, in other words, no doubt the destruction is inevitable occurs if the hollow anchor bar supporting system that has no the pressure and yield properties. The anchor bar can be lengthened as required so it is well applicable to railway, tunneling, mining, hydroelectric station, slope stabilization, dam, bridge foundation, river, breakwater, high- rise construction infrastructures and other projects. With the usage of high quality hollow anchor bar, the settlement, collapsed holes, fissures, landslide and so on will be simpler. Meanwhile, it’s also very convenient for operating in narrow space or with limited head rooms and the quality of anchorage material is incomparable.

As the global redevelopment of urban areas continues, either by redesigning existing or by building new structures, the need for a cost-efficient method to stabilize structures in these sensitive areas is increasing. Self drilling injection anchor is used to attach objects or structures to concrete. There are many types of this kind of rock anchor, consisting of designs that are mostly proprietary to the manufacturing companies. All consist of a threaded end, to which a nut and washer can be attached for the external load. It can provide an excellent effect on various kinds of complex conditions, such as soft soils, loose rock, fractured zones and so on. The self drilling injection anchor is versatile in the projects of mining, tunneling, transportation, different kinds of foundation support and national defense and so on.

Sinorock is an outstanding self drilling bolt supplier and offers the best self drilling injection anchor that serves as an economical solution for challenging soil conditions where installing conventional micropiles may not be the best option. For example, those with collapsible soils (those not conducive to open-hole drilling), large boulders, or other obstructions. Different kinds of drill bits can be provided to meet the demands of different rock conditions. With good quality and excellent service, Sinorock has won great reputation from all over the world.

Rock bolting systems are used to stabilize excavated rock mass in underground mines and tunnelling. Rock bolts are systematically arranged to transfer the load from the unstable surface or exterior of the rock, to the much stronger interior part of the rock. The rock mass can be reinforced by different types of rock bolts.

As an efficient placing approach, self drilling rock bolt palys a significant role in supporting rock mass to prevent deformation and excavation,buildings,roadway,bridges,large equipment are all established on the rock, so the stabilization of rock layer will be extremely important. Self drilling rock bolt system is widely used in foundation reinforcement projects, such as railway, tunnel, mining, hydropower station, dam, bridge base, water bank, high building foundation etc., also widely applied in solving geological disaster, such as foundation subsidence, hole collapse, break, collapse, and landslip etc.

Features of self-drilling anchor system are as follow:

1) There is a bit with high penetrability on the top of self-drilling anchor system, it can penetrate into many kinds of rocks with common rock drilling machinery.

2) Self-drilling anchor system has continuous wave form thread of international standard, it can be used to drill into anchor hole with bits.

3) As a drill pipe, self-drilling anchor system doesn’t need to be pulled out. Its hollow can be the grouting channel.

4) A dynamical stop plug makes strong grouting pressure for grouting so that voids can be filled completely, broken rocks can be fixed, high-strength plates and nuts can pass the stress of deep surrounding rocks on perine surrounding rocks so that surrounding rocks and anchors can support each other.

5) A dynamical coupling set made by mechanical cutting process makes self-drilling anchor system can be lengthened while drilling so that it can be applied in smaller construction space.

6) Because of its trinity system, some special techniques such as casing pipe wall protection and pre-grouting are needless to make sure a good effect of drilling, anchoring and grouting. place.
