Swellex quality assuranceWe believe that assuring quality throughout the complete supply and distribution chain is the best way of ensuring the highest level of safety and productivity for our customers.

All Atlas Copco Swellex products are manufactured according to strict ISO standards. Stringent quality control assures that high quality materials are used. Exten-sive quality testing is performed to assure that the products meet the Atlas Copco brand standards.

Each bolt has an alphanumer-ic code stamped on the bush-ing head, making it traceable through the recorded results of testing done at each manufactur-ing stage. Each and every bolt is

tested for leakage as part of the production process. This unique operation is augmented by full ex-pansion in open air at 10% above recommended installation pres-sure. One sample bolt is removed from the production at the begin-ning of each shift and one when a new batch of steel profile is used. This means that 1% of all bolts are sacrificed in the name of quality assurance.

We follow EN and ASTM stan-dards to report elongation and

tensile load capacity. Further-more our bolts are tested in full section, expanded into a borehole dummy to simulate working con-ditions that are close to, the real use of product.

The Swellex systemInstalling a perfect rock bolt

Interaction during installation

1. Drill the hole.

2. Swellex bolt is placed.

3. Water injected under pressure forms the tube to the irregulari-ties of the bore hole, generating friction and mechanical interlock-ing.

4. The internal pressure is re-leased leaving a permanently de- formed tube that is locked in place providing a strong interac-tion with the rock mass.

The Swellex system

The system consists of specific rock bolts made from steel tubes that have been folded onto them-selves, bolting accessories and specially designed, high pressure, installation pumps.

Swellex rock bolts are placed in drilled holes and expanded using water from the installation pump. The high pressure water causes the bolts to expand, filling the drill hole, consolidating any loose ma-terial remaining after drilling and conforms to the irregularities of

the hole. A combination of fric-tion and mechanical interlock is generated throughout the entire bolt length.

Swellex bolts interact directly with the rock without the need for such auxiliaries as grouting agents or locking devices. Simply monitor-ing water pressure provides qual-ity control during installation.

1. Drill the hole. 2. Insert Swellex bolt. 3. Expand the bolt until preset pressure is reached for 6 seconds.

4. Perfect installation completed.

It is a true alternative as long secondary support to secure potentially unstable areas or to control dilution while boosting productivity. By simply connecting two, three or more specially adapted Swellex rock bolt segments, you create a custom-made long rock bolt, able to penetrate deep to stable rock.

Immediate support

It is ideal as secondary reinforce-ment in difficult areas, as long an-chors in stopes for dilution control or where other long anchors have problems with excessive water.

Quick installation

No curing time! No special crew! Recent tests have shown up to four fold increased productivity when compared to manually and semi-mechanized installed cable bolts.

Peace of mind

By reaching recommended ex-pansion pressure you are assured of a perfect installation on the en-tire length of the bolt irrespective-ly of presence of water in the hole.

Installation

The Swellex Pm24H is a new gen-eration of Swellex bolt that pro-vides strong hanging capacity. The bolt has a flanged head with a female M36 thread which is first coupled to an expansion bushing for installation.

After installation the expansion bushing is replaced by an eye bolt. The rock bolt has a static axial load carrying capacity of 200 kN, how-ever it is limited by the capacity of the eye bolt. Swellex Pm24H can be installed using standard Swel-lex installation equipment.

NOTE: Pm24H reported perfor-mances are only valid for axial load with no dynamic or cyclic loading.

The Swellex hanger bolt offers the possibility to have a strong hanging point using Swellex technology.

From a distance, the cave in the side of Turkey’s Mount Starius, close to the Syrian border, looks no different to the many others that are found in this part of ancient Europe. Howev-er, this one is no ordinary cave.

Measuring 13 m deep, 9.5 m wide, and 7 m high, it is believed to be one of the first founding churches of the Christian faith and a place where none other than the first apostle, St. Peter, once preached the gospel.

What is known for sure is that the site, which now has walls, colonnades and an altar, was established as The Church of St. Peter in the 4th century.

Today, it is a museum and one of the most popular tourist attractions in the country, but in recent years it has

been subjected to frequent rockfalls which threaten to destroy the church for all time.

Immediate supportTo save and protect this iconic site, a spectacular rescue operation was recently carried out in order to elimi-nate the immediate risk of more rock-fall and to secure the mountainside for as long as possible. For this work, Turkish contractor Kuzey Dagcılık, used professional mountaineers armed with modern rock stabilization technology from Atlas Copco.

Suspended from climbing ropes high on the mountainside, they drilled a series of 48 mm holes into the rock face with Atlas Copco drill bits, using stabilizer bolts on the rock drills to prevent deviation. Each hole took ap-proximately 10 minutes to complete.

Atlas Copco Swellex rock bolts were hoisted up the rock face and inserted in the holes. Next, a Swellex pump was hoisted up and used to inflate the bolts. The total installation time was about five minutes per bolt. In this way, the section of the rock face, that posed the greatest danger to the church, was stabilized.

To achieve this objective, the moun-taineers needed only 25 plastic coat-ed Pm24 Swellex bolts, 3 m and 3.6 m in length. As soon as the bolts had been inflated, they provided immedi-ate support to the weight of the rock mass and, on some sections, wire mesh was also used.

Conclusion:According to Fatih Tomba, Site Man-ager, the possibility of further rockfall has been averted. “We came here to clean up the surface of the mountain-

The Starius Mountain in Turkey consists of limestone forma-tion. The cracks were between big rocks and main rock body. To decrease the rate of corro-sion, generated by acidic effect of underground waters, plastic coated Swellex rock bolts were chosen to save and protect the 4th century Church of St. Peter from rockfalls.

side and found that there were huge sections of rock that were in danger of falling at any moment,” he explained. “It obviously needed immediate at-tention.”

In Tomba view, there was no alterna-tive to the Swellex bolt, saying: “It was the only rock bolt that could do the job properly. If we had used stan-dard rock bolts I think they would have come down along with the rock mass. Due to the inflatable design and immediate support capability of the Swellex bolts we are confident that this won’t happen.”
