For this reason, the Split Set Group offers a free application engineering service to assist you in the selection of the proper Split Set configuration

The Split Set stabilizer installation is very easy and rapid as 1-2 ! 1- drill the hole. 2- drive the bolt until the plate is in contact with the rock. Split Set stabilizers, model SS39, can be

Split set rock bolt can be load tested by fitting a special ring to the bolt prior to its installation. Pull tests can then be conducted with a hollow ram hydraulic jack. 2.The installation is the simple. 3.No anchoring agent is required. 4.The friction strength between the bolt and the rock is large. 5.It has high shear and tensile strength.

DOME PLATE As a kind of ground support Split Set Bolt used in applications, Dia.33mm also has a C shape pipe of bolt body which can offer an instant frictional forces that holds the rocks together, so it is also widely used in mines, tunnels and slopes etc. However meanwhile, the material strengt

A few points of knowledge. (1) After the split set Rock Bolt is installed, it can immediately apply three-dimensional stress to the surrounding rock to actively reinforce the surrounding rock. (2) The Split Set Rock Bolt is a full-length anchor rod, and its rod body is also elastic and flexible, so it can effectively resist the shearing force

The length chosen should be the same as with other types of rock bolts, and installed with the same spacing. The stabilizer is installed with the same drill 

The upper part of the anchor is formed into a cone. The lower part has a retaining ring for mounting the washer. When set in the hole, the bolt is given the 

Load cells were placed on the head end of the bolts to determine head loads. Head loads up to 14.7 kN (3,300 Ib) were generated during bolt installation. In 

A system of twelve equations have been developed for the elastic-plastic analysis of split-set roof bolts and these equations have been programmed for 

Fast, easy installation takes usually less than a minute - just drill and drive. Split Set® stabilizers come in 3 models. They are available in lengths and sizes to meet your needs and are

Easy Installation The Split Set is a popular choice due to its easy installation. Once the hole is drilled, the driver Split Set / Friction Bolts are available in 33mm, 39mm, 41mm and 46mm diameters in a variety of lengths to suit the application of the mine. The domed bearing washer plates are

UTILITY SPLIT SET HANGER BOLT Split Set Utility Hangers can also make screen and mesh installation much easier, faster and safer. After your opening is secured with standard Friction Bolt, install the mesh all at once by driving friction bolt Utility hangers inside the tubes. No new holes are nee

The increased load transfer capacity of the grouted bolts provide an alternative for permanent excavation support using split sets stabilizers.

The split-set bolts is hammered into the hole, which has a slightly smaller diameter than bolt. Using the correct hole size for a specific bolt diameter is essential for successful installation. Split set bolts are very suitable for layered formations. The Split-set bolts provide immediate support but only for fairly short period of time.

Oct 08,  · Installation can be done in a few easy step: 1.Drill the hole. 2.Replace the drill steel with a driver tool. 3.Slide the plate on the tube. 4.Drive the tube in with the drill / drifter Rock Bolt Pull Tests Prove Sustained Grip Pull tests help verify the effectiveness of the stabilizers upon installation and over periods of time.

The installation of Split Set stabilizers is a fairly straight-forward procedure and can be performed easily by trained personnel. The diameter of the bit should be measured and the length of the hole should be at least two inches longer than the bolt.
