Best hollow bar system

Self drilling hollow bar system has been widely used, it can create great effect on anchoring and restraining weathering by ejecting concrete.This kind of method can improve the whole carrying capacity of surrounding rocks and prevent collapse.In the field of
Self drilling hollow bar system manufacturing area,Sinorock should be put on the first place.

Self drilling hollow bar consists of hollow anchor bar, drill bit, anchor coupling, anchor plate, anchor nut. self drilling hollow bar combines drilling, anchoring, grouting in a single process.
For every part of the self drilling hollow bar, each accessory has its own function. Anchor coupling is used to connect two or more anchor bars together to extend the length of the self drilling hollow bar. Drill bit is used to drill hole in the rock. Anchor nut and anchor plate required tension.

Self drilling hollow bar can be installed into many kinds of soils and ground conditions, such as sand, gravel, inconsistent fill, boulders, rubble and weathered rock, and so on. self drilling anchor bolt can be used to soil nail for road widening, railway embankments, ground anchors temporyary works and sheet pile tie back. It also can be used to mini piles for stabilisation of footing and underpinning, roof bolts or spiles for tunneling.
Sinorock now manufactures and supplies a complete range of hollow anchor bar products and technical services to the related industries,such as the civil and tunnelling industries.
Sinorock acts as a strong partner and manufacturing hollow anchor bar supplier for the mining,
tunneling,slope stabilization and foundation support industry, devoted to provide the best products and services to its customers including design, development, production and galvanization with on demand construction installation services and maintenance options.
Sinorock’s hollow anchor bar system 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.

Cost-effictive hollow bar

Self drilling hollow anchor bar system, one of efficient supporting methods, has played important role in reinforcing and supporting engineering. As for underground engineering, such as metro station and foundation pit supporting, self drilling anchor system can bond itself to soil and ground, which can enhance integrity and cohesiveness, avoid deformation and collapse.
Before construction of self drilling anchor, there are several preparing works to be done:
1. Master conditions of basic and underground pipelines in construction area.
2. Judge adverse effects from self drilling anchor construction to surrounding structures and pipelines. Relevant precaution measures should be planned, in advance.
3. Test self drilling anchor’s production craft, methods of tension and lock, equipment.
4. Identify grouting craft and grouting equipment.
5. Check raw materials’ variety, quality, model and inspection report.
Main construction equipment during process are drilling machine and grouting equipment. Before equipment entering construction site, they should be checked completely.
There are two kinds of professional people at construction site: technical operator and contributor. To guarantee their safety, all the design and operation works should be abided by the rules, especially at underground and closed space.
