micropiles can be used as self-drilling reinforcing elements for nailing to DIN EN 14490. The hollow steel bars are installed with drilling and flushing fluid and subsequently grouted with a cement suspension in a dynamic process. Carbon, Alloy and Stainless Hollow Bar - Product Stocking Alloy steel hollow bar Atlas Steels can supply both 4140 and 4340 grades of alloy steel hollow bar, compliant with ASTM A519M or equivalent specification and supplied in various conditions, usually hardened and tempered, but also annealed or as-rolled conditions subject to the specific application. 4145H MOD drill collar material is also available.

China Q345b Precision Hollow Bar Black Iron Seamless Steel Seamless Iron Pipe, Seamless Line Pipe, Seamless Low Carbon Steel Pipe manufacturer / supplier in China, offering Q345b Precision Hollow Bar Black Iron Seamless Steel Pipe / Tube Usded as Nitrogen Drilling Pipe, Hot Dipped Galvanized Z450 Zinc Coating Mass A36 Carbon Steel Medium/ Heavy Metal Plate, HDG ASTM A283 Grade C Mild Carbon Steel Plate / 12mm Thick Galvanized Steel Sheet and Geo-Drill Hollow Injection Anchors Williams Form Geo-Drill Hollow Injection Bar The Williams Geo-Drill Injection Anchor System is todays solution for a fast and efficient anchoring system into virtually any type of soil. The system has historically been known as a self-drilling anchoring because the hollow fully-threaded bar serves as both the drill string and the grouted anchor
Hollow bar products are a valuable and multi-functional addition to the geotechnical contractors toolbox. They can be used as tie back or tie down anchors, rock anchors, soil nails and micropiles in a large array of challenging applications. There are three basic types of drill bits for use with hollow bars. Hollow bar systems - AGL Manufacturing LTDThe AGL hollow bar system consists of fully threaded steel bars, couplers, a nut and various drill bits - which allows for the system to be drilled through various soil and ground conditions. Soil nail projects employing the AGL hollow bar system enjoy faster installation time compared to the traditional solid bar and casing method.

The hollow bar is continuously threaded, it can be cut and coupled anywhere along its length. The coupling enables direct end-to-end energy transmission between each bar, reducing losses and ensuring maximum percussive energy at the drill bit. DRILL BITS. The sacrificial drill bit is an important part of the self drilling anchoring system. R51 Self Drilling Hollow Bar Soil Nail1. The size of drill bit can control drill holes size. Generally, the size of drill hole is about twice or three times as bolts diameter. 2. It is convenient for construction in narrow conditions. 3. Mortar can pack the whole bolt, it has good anti-corrosion. 4. Drilling, grouting and anchoring can be finished at the same time. Technical SELF-DRILLING HOLLOW BARS:GROUND ANCHOR, Self-drilling hollow bars were primarily developed as a loose overburden drilling system, where the bar can be drilled through loose or collapsing soils without the need for a casing and with the drill
Welcome to Srons Engineers. Established in 2015 to support the growing demand of our Rock Hardware Products with excellent customer service. Srons Engineers are the Indian manufacturers of Rock Bolts, Self-drilling anchor systems and Self Drilling Anchor Bolt parts like hollow bar & rod, threaded rods, tie rods, coil rods, anchor couplers, anchor adapters, anchor nuts, drilling bits Self Drilling Anchor Self Drilling Rock Bolt |MysiteThe self drilling anchor bolt works with drilling a hole in cohesive and non-cohesive soil or loose rock, with a sacrificial drill bit and a hollow rod. A resin is injected at high pressure into the hollow and cavity which reinforces the surrounding area, later the hollow rod is locked with a retaining plate. Self Drilling Anchor System - quality self drilling anchor SupAnchor has achieved the security application of 26,000,000 meters Self drilling hollow bar,Self drilling anchor bar,Self drilling anchor bolt in the world. SupAnchor® is the largest manufacturer of self drilling anchor system in Asia. SDA is a bolt system combined by bar and accessory for unstable conditions which can be drilled and grouted simultaneously.
Self drilling hollow anchor system is a bolting solution for difficult ground and rock conditions such as sand, gravel, silt, and clays, and in soft to medium fractured rock formations. The system enables drilling and grouting in one operation, making much more saving in job-site and project time. Self-Drilling Hollow Bar Anchor System - JENNMARSelf-Drilling Hollow Bar Anchor System The Self-Drilling bolt is a fully threaded hollow bar that initially serves as a drill rod, utilizing a lost bit. The thread is made to comply to ISO 10208. For use in unconsolidated ground or other difficult ground conditions Excellent for spiling (fore-poling) SupAnchor® R32 Self Drilling Hollow Anchor Systems SupAnchor ® Self Drilling Hollow Bars is an unique anchoring system and is todays answer to the increasing demands of the tunnelling industry and ground engineering for safer and faster production. The 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.
T40 Self Drilling Hollow Bar is anchored in stratum, which can tightly link materials with stratum and then transfer tensile force, which makes reinforcement of stratum and itself. Compared with traditional anchoring methods, Self Drilling Hollow Bar has obvious advantages. 0 DYWI ® Drill Hollow Bar System - DSI EMEAThanks to the self-drilling hollow bar system with simultaneous grout flushing, the installation procedure can be decisively eased and shortened. The DYWI ® Drill Hollow Bar serves as a drill rod. It is fitted with a lost drill bit at the top that can be adapted to different soil conditions. After each single section of 1 to 6m, the subsequent
