The right solution depends on the project. Factors to consider here are the length and depth of the sheet pile wall, the soil situation, and whether the sheet pile wall is a temporary or permanent.

Self drilling hollow anchor bar is a hollow, thick-walled, central drilling rod with a drill bit at the top. The hollow rod and the drill bit allow flushing or simultaneous drilling and grouting. The system is modular, meaning that the most appropriate configuration can be put together to suit on-site circumstances and the forces that apply. Because of the coarse external trapezium shape tread the rod can be shortened or extended if necessary, to create the desired length. The trapezium shape tread also ensures optimum adhesion between the cement grout and the self drilling anchor. All parts of the system can be supplied with or without surface treatment.

Comprised of the hollow anchor bar, drill bit and other fittings,the Self-drilling Anchor can enable the hole drilling and grouting to be done in one single cycle. It can eliminate the use of a casing to support the drilled hole which is easy to collapse and offer higher rates of installation than the regular rock bolts. The Self-drilling Anchor is used for rock bolting and grouting in softer rocks where there is loose ground or sections prone to collapse. Hollow bar anchors are created from steel tubing, and are installed in micropiles or piers to provide additional strength and support.

Self drilling anchor system are either injected during or after the installation process Thu, 07 Apr 2016 09:42:56 +0200 http://comunicati.net/comunicati/arte/arte_popolare/388586.html http://comunicati.net/comunicati/arte/arte_popolare/388586.html metiscn metiscn Metis brand has become synonymous with the anchoring product category it invented. From the self drilling anchor bolt to our latest initiatives, we continue to innovate and lead the industry with labor saving, high quality and performance Metis designs and solutions.

Self drilling anchor system are either injected during or after the installation process. For simultaneously drilling and injecting, which is usually performed in cases where the ground needs to be further improved or stabilized during installation, special rotary injection adapters, which are placed in between the shank adapter and the hollow anchor bar, are being used. These adapters allow that the bolt is installed self-drilling while the injection medium is added at the same time. Normally, self-drilling hollow bar bolts are injected after the installation process is completed. In doing so, the anchor head is connected to an injection adapter which is furthermore linked to a grout pump.The injection flow goes inside the hollow bolt upwards until the bolt’s toe, from there on the bolt is grouted outside bottom up until the grout flows out at the bolt’s head. The threaded bolt geometry ensures an optimum bond between the bolt and the injection medium.  

We take pride in our commitment to operational excellence, superior service and new product development that has guided the company through decades of growth by meeting the ever-changing needs of the commercial construction industry. Focusing on the needs of our end-users enables us to customize our product offering and service based on their requirements.

Self drilling anchor give workers saftey in tunneling Wed, 20 Jan 2016 11:48:51 +0100 http://comunicati.net/comunicati/istituzioni/comuni/basilicata/380732.html http://comunicati.net/comunicati/istituzioni/comuni/basilicata/380732.html metiscn metiscn Ever since the tunneling principals have found industrial acceptance, in particular for unconsolidated/fractured ground conditions, also self-drilling anchors have become an irreplaceable product.

The traditional deep excavation retaining method can not meet the requirement of the stabilization of large-scale underground buildings.

Especially in sandy cobble stratum where the ratio of finishing gas hole is very low, it must lead to high pressure for the grouting and anchoring later and increase the construction cost.

Metis self drilling anchor is composed by anchor head,anchor nut,bearing plate,couplers and so on,which plays a significant role in connecting drilling,grouting,anchoring with each other to make the construction easier and efficiency.

Generally,as an practical and reliable placing solution,self drilling anchor has been extensively applied in the mining,tunneling,foundation support,hydroelectric project and roadway support project and so on,with so many years of exploration and development,the techniques of the installation of self drilling anchor has became skillful and been trusted by our customers around the world.

Grouting is a so critical element to provide strong strength and bonding stress for surrouding rocks,with the whole wrapped of grout,the self drilling anchor can make a perfect effect on the operation of various civil constructions.

The facilitate of self drilling anchor is so easy that it’s the key elements for our agents to choose our anchoring products.We allows customization of self drilling anchor,so the length of rod body can be cut and connected as our customer’s specific requirements.

The Metis self-drilling anchors are part of the excavation process and serve as primary soil/rock support for:

• Radial consolidation of the tunnel circumference supports the rock, forming a load bearing ring thus enabling the rock supporting itself

(together with shotcreate and other facing elements).

• Umbrellas and Fore poling as pre-support in poor rock formation, shallow overburden and critical stress conditions.

• Face stabilization to sustain rock pressure for excavation with large cross sections.

• Root piles to divert stress.

The conventional method of installation involves drilling the self-drilling anchor with water flush to the design layout and depth and in a second phase, independent of drilling, a grout adapter is added and a dense cement based gourt mix is injected through the hollow core to exit through the flush holes at the drill bit filling the borehole annulus until the grout mix appears at the borehole mouth, once cured, enabling the transfer of stress from the rock/soil formation.

If you have any question please don’t feel any hesitate to contact us at any time,we have professional R&D team to offer best and economical drilling solutions,which will make your operations easier and efficient.

It is Sinorock management’s belief that only qualified raw material can possibly produce perfect products.We choose only to cooperate with reliable suppliers and reach a strategic partnership with them. 

Cooperation 

Based on the strategic partnership cooperation, the suppliers provide us sufficient technology support which helps us to implement our cost-saving, quality-upgrading and product-developing programs.

Correspondence

A favorable communication and information-sharing system has been developed through long term cooperation which gives us advantage to be sensitive to every change of raw materials in the market and make immediate responding to cost and delivery time accordingly. A powerful risk-resistance ability is therefore formed.  

During the cooperation with suppliers, an information sharing system has been developed between suppliers and Metis, which enables Metis to get the first  information on raw material updates and dynamics in time, guarantees time and continuity that raw materials arrive in Metis. That is the reason why Metis is so strong in resisting risks. 

Character
