Reinforcement rods structure

Self drilling hollow anchor bar system is the rock and soil reinforcement rods structure. It is one of the main supporting forms of rock slope for underground,plays an important role on stability of civil engineering maintenance, especially it has obvious effect in the joints and fissures in rock mass and anchor rod on rock reinforcement.The self drilling anchor system of the alloy bit has strong penetrating power, under the action of rock drill, can easily penetrate all types of rock mass, and using the exhaust of the anchor head up thoroughly solve the problem above the horizon of the grouting exhaust.
Recent years, self drilling anchor is a new method for supporting global projects, which
has been applied in several projects, such as civil construction, mining, hydroelectric
station and tunneling.Self drilling anchor bolt can not only make construction more
convenient and efficient, but also have effect for permanent supporting. Stainless self
drilling anchor bolt and duplex coating rock bolt are all the anti-corrosion products in
Sinorock. They have not only beautiful appearance, anti-corrosion quality, but also good
strength and high wear resistance.

Sinorock high quality self drilling anchor system works to stabilise foundations and support
structures for excavation, making worksites safer. We work closely with geotechnical
engineers to assist with project design and selection of anchor type after consideration of
ground conditions, ensuring lasting integrity of all our self drilling anchor systems.
Sinorock is your trusted resource for the best tools and accessories for construction and
concrete. We have the highest quality self drilling anchor bolt that are sure to meet your
needs. Our products are offered at competitive prices and are from the best industry brands.
If you want to place a single order or you need a larger supply we have the solutions you
are looking for.

Hollow Bar Micropiles

Hollow Bar Micropiles are drilled into the ground using a sacrificial drill/grout tip while
pressurized grout is pumped down the hollow bar while drilling. Micropiles can be used for
practically any soil condition and load is gained through bond stress between the grout and the
surrounding soils.

Micropiles have the advantage of being the one piling system that has the best chance of penetrating
obstructions during installation. A wide variety of drilling tips are available for different soil
conditions.
Self-drilling hollow bar methods are also used, involving a hollow anchor bar, a sacrificial bit with
ports, and an external full depth or partial depth casing as needed to control overburden soils. In this case grout is pressurized down through the hollow bar, out the grout ports and a pressure head
is maintained such that the annulus in the soil around the bar is pressurized with grout. When full
or partial depth casing is used, the frictional capacity must be adjusted. The casing in the upper
sections of a micropile can also serve to increase lateral resistance and bending resistance for the
micropile and can assist with more versatile connections to structural components at or above grade.

Sinorock strives to meet your specific hollow anchor bolt needs so you can compete in the anchoring
industry. We offer a wide range of services that add value to your company. The company has
