self drilling hollow bar

The self drilling hollow bar of Sinorock is involved in many areas of the construction field. A few examples of our specialties include tunnel rehabilitation and enlargement, soil stabilization, rockfall mitigation, shaft construction,
shotcrete, culvert installation, soil nail and rock bolt installation.

Sinorock self drilling hollow anchor bolt effectively improve the stability of underground rock masses. The increased load bearing capacity of the rock conditions enables an early construction start, thus providing both technical and economic advantages.

As a leading specialty geotechnical construction firm, Sinorock provides a full range of ground engineering techniques and solutions, related to earth retention, foundation support, ground improvement, and ground treatment.
Today, after these years, by enjoying a considerable expertise in rock bolting industry, we are honored with our history of importing andintroducing some kinds of self drilling hollow anchor bolts in various ranges of capacities to the demanding construction market in our country,together with consulting projects for the purpose of addressing the best location and the optimum choice of capacity, plus extensive sales and after-sales services, providing timely spare parts support, all in accordance with engineering standards worldwide.

Sinorock quality hollow bar anchors are extensively used for connection applications within the construction, engineering and manufacturing industries. Our largest market is the construction industry where we offer our customers highly engineered anchoring products for precast concrete elements; curtain wall and building facades; structural connections within commercial, public and residential construction; as well as anchoring solutions for tunnels, civil engineering and transportation structures.

Self drilling hollow anchor is an anchorage measure to integrate drilling, grouting and anchoring functions. It has the advantages of fast speed, large anchoring force, good corrosion resistance and simple operation, etc. In the Jinhe Hydropower Station construction, R25 and R32 self drilling anchors were used for tunnel support and slope reinforcement.

Sinorock – The company has the privilege of serving most quality conscious customers in the industry over the years, we have built up the reputation of being a reliable and quality self drilling bolt supplier source to our esteemed clients.

Rock reinforcement and ground control are key issues in underground excavation.
One scope of research, which is in particular of interest for underground tunnelling,are self-drilling hollow bar systems. In the past decades, substantial technical advances in the development and design of these systems have been accomplished. On the basis of some practical examples, this manuscript illustrates the development and successful application of self-drilling rock reinforcement systems.

The main features of all hollow bar anchors and rock bolts are the application of a single-use drill bit in combination with the anchor rod being used as a drill steel. Thus,the anchor or rock bolt is connected to the hydraulic rock drill by an adapter device and installed in the way a conventional borehole is drilled.

The self-drilling installation of the bolts is accomplished similar to the drilling of a conventional borehole; the hollow anchor bar is connected to the shank adapter via a coupling and is being utilized as

3 drill steel; the single-use drill bit is put at the top of the hollow bar. In case where larger bolt lengths are required, the anchor bars can easily be extended by couplings.

With the continuous increase of mining depth, the geological conditions of mining engineering is facing more and more complex, more and more problems of the roadway support occur.The soft, under the condition of high stress roadway support problem bothering mining engineering for a long time.

Self drilling hollow anchor bar was developed rapidly due to its superior performance, and it is widely used in many areas of civil engineering.As one of the main supporting forms of rock slope and underground engineering,the hollow anchor bar plays an important role for the stability of civil engineering maintenance , especially in the joints and fissures in rock mass.

The main anchoring method in a natural formation is in the form of borehole grouting, namely, hollow injection anchor. Anchorage method in the artificial filled soil anchor plate and reinforced in two ways.

When engineering decided to adopt what kind of hollow injection anchor, we need to cope with the force of the buildings and the anchoring formation properties, groundwater and other geological conditions and the overall stability of a full investigation.
