JB ROCK BOLT SYSTEM Grouted Rock bolts have been commonly used world- wide in mining and civil engineering applications. The most used grouted Rock bolt is the fully grouted rebar or threaded bar made of steel. Cement or resins are used as grouting agent. The rebar used with resin creates a system commonly used for tensioned rock bolt but the rebar or the threaded bar with cement grout can also be used for un tensioned bolts

JB Engineering Soil Nails JB Engineering Soil Nailing is a technique that can be used either on natural or excavated slopes, where the slope is reinforced by the insertion of tendons. The nails address the slope stability, which are connected in turn to a facing system and provides surficial stability. JB Engineering Offers different types of anchor bars for use in conjunction for rockfall protection and natural hazard mitigation. These are used for numerous applications. JB Engineering Anchor Bars are Available in different Diameters 25mm, 32mm, 36mm, 40mm , steel strengths and corrosion protection, as per IS Code 12594-1988, and/ or epoxy coated- as per IS 13620;1993. JB Engineering Make Accessories Like Joint Couplers, Anchor Plates and Anchor Bolts are also available as per Project requirements and ground conditions. The Various Components of JB Engineering Make Soil Nails are: 1. Steel Reinforcing Bars: The solid steel Reinforcement Bars with minimum strength of Grade 500/550, 670/800, 950/1050 are the main Components of the soil Nailing System.These are Placed in predrilled drill holes and grouted in place. 2. Centralizers: PVC Centralizers are fixed to the soil nails to ensure that the soil nail iscenter in the drill hole. 3. Nail Head: The Nail head is the threaded end of the soil Nail that protrudes from the wall facing. It is a square shape Steel Structure, which includes Bearing Plates, Nuts.JB RE-BAR Couplers are used to extend the Length as per designs of the Project. This Part of the Structure Provides the soil Nail bearing strength, and Transfer bearing loads from the soil mass to Soil Nail. 4. Hex Nut Washers and Bearing Plates are attached to the soil nails Heads and are used for connecting the soil Nails to the facing. Bearing Plate distributes the force at nail end to temporary shotcrete facing.

Pipe Umbrella System--Ground Engineering Fore Poling Technology.

JB Engineering Pipe Umbrella System is a pre-support measure used in weak ground conditions in conventional as well as mechanized Tunneling. Long fore poling using the pipe umbrella or canopy method is typically applied to increase safety and stability in the working area of standard advance operations, portals, and for re-excavating collapsed sections. Another application is ground improvement and waterproofing in combination with all tunnel construction methods.

JB Engineering Pipe umbrella pipes installed into the ground prior to excavation increase the stability in the working area by transferring loads in the longitudinal direction and decrease excavation induced deformations. JB Engineering has developed a superior pipe connection type, which allows the reduction of installation cycle times while increasing the load-bearing capacity. State-of-the art pipe umbrella support systems are installed self-drilling where the casing provides an immediate support of the borehole, compared to outdated pre-drilling systems where borehole drilling and pipe installation takes place in two different working steps.

Fully mechanized installation is becoming a mandatory safety standard in the global Tunneling business. JB Engineering is the leading system supplier in the development and application of safe and efficient pipe umbrella installation technology.

JB Engineering system comprises steel pipes installed from the tunnel face to form a roof to stabilize the tunnel headings. By distributing the load in longitudinal direction, it can decrease deformation during excavations.

JB EngineeringsDouble Corrosion Protection (DCP) Anchors are HOT DIP ZINC Coated & Fusion EPOXY COATEDwhich provides protection from Corrosion for minimum 100 Years with two independent barriers between the anchor tendon and the environment.Grouted corrugated sheathing with controlled crack widthand are for permanent use. Mostly used in high rise construction for heavy reinforcement.

• Ground anchors are unique as they can provide active restraint to the structures.
• Anchors avoid movements by applying a compressive load to a structure.

JB Engineerings(DCP) - DOUBLE CORROSION PROTECTION Anchors classifies as like below:

• The application of ground anchors is increasing as they enable construction in densely populated areas. This increase is due to the reductions in available space for traditional construction methods.
• In areas of limited easement, removable anchors can be used. For projects where further underground construction, like adjacent developments of tunnels is anticipated engineers can use resized anchors produced from composite materials.

Features of DOUBLE CORROSION PROTECTION Anchors are:

• Hot Zinc Coated / Fusion Epoxy Coated anchors provide minimum 100 Years Corrosion Protection.
• Bond length and free length to enable pre-stressing.
• Capacities: bars 4, 500 kN, strand15, 900 kN(+)
• Anchors with diameter range12-75mm strand anchors up to 63mm(+)
• Full compatibility with infrastructure intelligence, utilizing multiple sensor types.

How ground anchors work: -JB EngineeringPre-stressed grounds Double Corrosion Protection (DCP) Anchors are HOT DIP ZINC Coated & Fusion EPOXY COATED provides protection from Corrosion for Minimum 100 Years & more actively contribute to the stability of a structure throughout its design life. The performance of the anchor is critical to the stability of the structure.

Stressing jacks are used to pre-stress the anchor and elongate the tendon. Once the necessary load has been established, the anchor is locked off at the head. The anchor then applies a compressive load to the structure to arrest movement.

The anchor is un-bonded from the ground between the structure and the load-bearing strata to prevent load from being transferred in to unsuitable material and to ensure that sufficient elongation of the tendon is possible. Upon reaching the desired depth, the tendon is directly bonded to the ground, forming the two fundamental elements of the ground anchor: the free length and the bond length.

In permanent work, anchors need to be protected against corrosion in line with internationally recognized anchor design standards. Double corrosion protection (DCP) is provided withHOT DIP ZINC coating process & fusion EPOXY COATED processwhich provides protection fromCorrosion for Minimum 100 yearswith two independent barriers between the anchor tendon and the environment.

JB Engineering Zinc Coated /Epoxy Coated TMT Bars are highly corrosion resistant variant of steel bars which are protected by Fusion Bonded Epoxy coating. Fusion Bonded Epoxy coating, commonly used to protect concrete TMT bars, steel pipes, piping connections etc. used in construction.

Fusion Bonded Epoxy coatings are in the form of dry powder at normal atmospheric temperature. The powder is applied electrostatically to the surface of cleaned steel bars and cured to form a protective film after undergoing various chemical processes. The epoxy coated bars last longer due to the protective application and contribute to the quality of construction.

JB Engineering Fusion Epoxy Coated TMT Bars are available in Grades 500D/550D/600D/670/800/950/1050 Mpa & Sizes From 6mm to 50mm.

jb-self drilling anchor bolts

the self-drilling hollow bar anchor-system is comprised of a hollow threaded bar with an attached drill bit that can perform drilling, anchoring and grouting in a single operation. the hollow bar allows air and water to freely pass through the bar during drilling to remove debris and then allow grout to be injected immediately after drilling is completed. grout fills the hollow bar and completely covers the entire bolt. couplers can be used to join hollow bars and extend the bolt length while nuts and plates are used to provide the required tension.

jb engineering offers self drilling anchors in variants of r25, r32, r38, r51 and t76 and their accessories including the anchor nut, anchor plate, anchor coupler and drilling bits depending on the geological condition of the project site (type ex, exx, es, ess, ey, eyy).
