Sinorock anchor bolts are used to fasten in foundation structure

In petrochemical facilities, anchor bolts are used to fasten process vessels or machines to
a foundation structure, thus allowing the loads to be transmitted to the foundation, and
ultimately to the earth. As with concrete infrastructure, all too often anchor bolts are
taken for granted and the thought of providing a maintenance budget for these critical
fasteners is more often an afterthought, or a direct result of a failure. Anchor bolt
failures, in some instances, can generate a process outage or a more serious accident
involving personal injuries, such as when conditions precipitate a ‘failure without notice
The expert one-stop-shop anchor service offered by Sinorock provides reassurance that your
anchor bolts will perform to specification time after time.
The requirements for critical SDA bolts are many and varied. They can range from
holding-down bolts that withstand seismic disturbances through to attaching cladding panels
on modern buildings and the permanent fixings for advertising hoardings. Whatever the
need,Sinorock will work with you to design, install and test a complete solution.
Sinorock is often the culprit in anchor bolt failures, allowing insidious corrosion
processes to accelerate unnoticed when the anchor bolts are hidden from view by insulation
materials. Recognizing telltale signs, such as rust staining though insulation systems,
increases in vibratory movement, and misalignment of equipment; can provide owners/operators
with the risk reduction opportunities when coupled with a thoughtful assessment strategy.

Use of self drilling anchor bolts upon on Characteristics of Soft Soil Foundation

Characteristics of Soft Soil Foundation

1. Because of many and big interstices in soft soil, and plenty water content in it, soft
soil can be compressed easily. So soft soil has feature of strong compressibility. And quite
bigger uneven settlements appear easily in soft soil foundation.

2. Under external pressure and disturbance, soft soil structures will be damaged, so it has
weak resisting strength. Soft soil foundation will often occur landslide, settlement,
collapse, etc. All these situations are mostly caused by pressure and vibration, which also
proves soft soil’s weak resisting strength.3. Owing to the peculiarity of soft soil sedimentary environment, soil textures’ evenness

is not strong. If soft soil foundation has improper treatment, uneven settlement phenomenon
will be happened.

4. According to experimental analysis, there is plenty water content in soft soil, at the
same time, water permeability is poor. Same water content in different kinds of soil, soft
soil water penetration speed is slower than others. So, it needs cost more time to settle
soft soil when constructing buildings above soft soil foundation, which will also influence
its foundation performance directly.

Self drilling anchor system combines functions of drilling, grouting and anchoring together, which is suitable for loose and soft soil condition. Slurry fills interstices in soil texture from bottom to top, squeezes water and then it can reach the function of reinforcing soil body and supporting engineering.

Sinorock self drilling anchor bolts are made is mostly used in mining, tunneling,under 

ground working environment, these anchor bolts are machine friendly which reduces the time
of installation, our anchor bolts are compatible with resin type grouting or cement grouting
with many optional accessories like dome plate, plain plate, conical washer, spherical
seats, Couplers etc.
Sinorock has the excellent SDA bolt system for foundation treatment,Sinorock SDA bolt system
– your worldwide partner for innovative systems and solutions for the tunneling
Construction,slope foundation and Mining industries.

Micropiles are made of hollow bars or steel rebars with diameters of 20 to 130 mm

Micropiles are small diameter drilled and grouted friction piles. Each pile includes steel elements that are bonded into the bearing soil or rock – usually with cement grout. The bearing stratum is logged during installation drilling to assure that bearing capacity is adequate. Micropiles do not rely on end-bearing capacity, so there is no need to establish the competency of rock beyond bond-depth. They can be installed quickly in virtually every type of ground using highly adaptable mobile drilling equipment.
Micropiles are rapidly gaining popularity for foundations in urbanized areas or in locations with low headroom and restricted access. They are an ideal choice for underpinning or emergency repairs because they can be installed in virtually any ground condition with minimal vibration and disturbance to existing structures.
Micropiles, also called mini piles, are often used for underpinning. They are also used to create foundations for a variety of project types, including highway, bridge and transmission tower projects. They are especially useful at sites with difficult or restricted access, or with environmental sensitivity. Micropiles are made of hollow bars or steel rebars with diameters of 60 to 200 mm. Installation of micropiles through top soil, sand and cobblestones overburden and into soil rock can be achieved using Air Rotary or Mud Rotary drilling, impact driving, jacking, vibrating or screwing machinery.

Many different structures incorporate rock bolts into their construction

The rock bolts ,which may also be used as an avalanche protection barrier in addition to its usage in foundation piles and support piles, offers comprehensive solutions to users.Rock bolt is an incredibly versatile product known for its low density, outstanding corrosion resistance, and energy efficiency. Engineering on the rock bolt is usually the General term referring to the tension-compression component’s anchoring system.It contains the anchor solid, tie rod and anchor head three basic parts.Rock bolt support has both bracket and reinforcement function,and has a number of distinctive features,for example,it will provide support after rock and soil excavation, to protect the strength of rock and soil, controlling the further extension of rock and soil mass deformation and improve the security of the entire construction process have a significant role.The rock bolt system has demonstrated that in the majority of medium strength soils ultimate loads in the range of 250 to 400 tonne can repeatedly be achieved. The system also has the advantage of being appropriate for use in environments previously considered unsuitable for traditional rock bolts.For projects facing geo-conditions above,rock bolts should be considered as the main solution cuz it’s designed for optimized installation, tailored to the project’s needs.Sinorock rock bolts are manufactured for underground or ground applications in mines, 

tunnels, slopes, or wherever reliable ground
support is needed. And nowadays,more and more countries are investing in tunneling,
infrastructure construction, hydroelectric projects,
High-speed rail construction, etc.Of course,more and more self drilling rock bolts are applied in the
constructions.With so many different
structures incorporate rock bolts into their construction, it’s not hard to believe that
Sinorock has taken large share of the rock bolts market.

Sinorock self drilling anchors were developed for economic purposes on projects

In liquefiable profiles micropiles can transfer loads
to competent bearing strata to conform to seismic design requirements. Underpinning of
foundations adjacent to planned excavations is another micropile application.
Sinorock has served the construction industry sereval years in custom manufacturing
anchoring systems for highway, building and other large construction projects.Sinorock has a
strong understanding of industries like mining and tunneling appliances, having worked
closely with several multinational clients on their requirement.
A key component to the success of these building projects was the development of micropiles.
Created using high strength steel in a small
diameter casing or threaded bar, micropiles can help give rigidity and structure to softer
soil content. Most often micropiles are used in
underpinning, to strengthen the existing foundation of a structure or building. Continued
development has led to micropiles capable of
supporting loads of up to one-thousand tons.
One of the newest micropile technologies is magnacore self drilling anchors. These were
developed for economic purposes on projects where
the installation of conventional micropiles was not the practical choice.
Self drill micro-piles are suitable for a variety of ground conditions including
clay, sands and gravels, made ground and weathered rock. They can be
installed through existing footings and base slabs.
Self drill micro-piles are installed using small scale piling rigs and are particularly
suited to axial compression and
tension loads and can easily be installed at raking angles.
Self drill micro piles are effective in a variety of ground conditions, including gravel,
clay, rock, sand and made ground. This method of
mini piling is used in a wide range of projects including rail related work and foundation
upgrades, stabilisation and underpinning as
well as facade retention, tension piles, road works and bridge works.
