Soil nail for project

A valuable brand in any industry is one that is reputably skilled and capable of performing what they have promised. For engineers, this means that the company should be approved and certified to ensure the quality of their work. Sinorock puts its name on the self drilling soil nail anchors manufacturing.
Continuing a proud heritage as the pioneer of self drilling soil nailing anchor systems, Sinorock further demonstrates its commitment to quality manufacturing and transparency of product performance, by increasing the number of independent accreditations to include CE Marking. Sinorock CE Marked products create additional security for Engineers, Architects and Specifiers as product performance is tested and confirmed by a third party to meet a standard, renowned on a European scale.
To accomplish complex drilling tasks like tunneling, grouting or slope stablization, Self drilling anchor is utilized for efficient performance. Our production of Self drilling soil nail anchor has increased progressively to cover the national markets due to the competitiveness level reached by our company after both the metal treatment technology innovation and the experience made in the field during these past years. The Self drilling soil nail anchor system of Sinorock has the high prise in the market.
Extensive project experience, combined with our expertise in all contracting methods, means Sinorock can make civil and transportation projects successful, no matter the constraints. Our experience includes construction of roads and highways, bridges and interchanges,airports, hangars, rail facilities, and water treatment plants. Sinorock has also completed many underground construction projects such as
water transmission and distribution lines, large fiber-optic communication installations, large and small sanitary sewer systems, and other underground utilities.

Slope stability with soil nail

Soil nailing support is suitable for loose and broken conditions, different size has different tensile strength and elongation rate. It has obvious effect than common supporting methods in project construction.
Soil nail wall support is consisted of dense soil nail group, soil body and sprayed concrete pavement. It is a compound and self-stabilized retaining structure, like gravity retaining wall, which aims to resist soil pressure and other loads and then makes foundation pit or slope stable.
The applied range of soil nail wall support is wide, such as: temporary support, permanent retaining structure, repair, rebuild and reinforcement of existing structures and support, etc.
Soil nails improve slope stability by:

(i) Partial increase in the the normal force and shear resistance along potential slip surface in frictional soils.

(ii) Direct reduction of driving force along potential slip surface for cohesive and frictional soils.

(iii) Soil nail head and facing provides containment effect to limit the deformation near slope surface.

Soil nail head serves to provide reaction in mobilizing tensile force in soil nail. Moreover, it provides confinement to soils in active zone behind soil nail head and avoids the occurrence of local failure between adjacent soil nails.

Self drilling soil nail system

Large quantity of engineering construction shows that broken rock mainly takes place in surrounding rock of tunnels, with the characters of deformation and abruptness, it’s hard to deal with the problems exist in tunnel support of hard tunnel only by self drilling soil nail, especially in the hard tunnel at jointed fractured zone.
Information on soil and bedrock hydraulic head (i.e., porewater pressures) is required for slope stability analyses of self-drilling anchored systems. The available piezometer and hydraulic head data for each water-bearing zone should be evaluated, but note that these hydraulic heads are likely to change as a result of seasonal changes in precipitation and construction activities that change or interrupt water flow paths.
For stability analyses, an envelope of maximum heads measured at different times of the year should be conservatively assumed. The required restraint force that must be developed by the self drilling soil nails and the wall will depend on the location of the wall relative to the sliding surface and the amount of material to be stabilized.
