How to Improve the Service Life of Self-drilling Soil Nails?

Soil nails can be used in clay, sand, and silt foundations with low groundwater levels, and the depth of the foundation pit is generally within 15m. However, how to support the foundation pit slope in case of broken, loose and easily collapsed rock formations? Of course, self-drilling soil nail. In many construction projects, soil nails are used to support foundation pit slopes and highway slopes. The service life of soil nails has a great influence on the later quality of the whole project. So, how can we improve the service life of soil nails? Today, Sinorock will introduce to you....

Soil nails principle

Soil nail is a kind of slender rod that is used to reinforce or anchor simultaneously in-situ soil. Rely on interface adhesion with the soil or friction in deformed under conditions of passive power and withstand tension. Soil nails are typically solid bars or fiberglass bolts that are installed into pre-drilled holes and then cement grouted into place using a separate grout line. A soil nail design life can be offered by placing the soil nails into plastic HDPE sheathing, and encapsulating the bars in grout, both within the sheathing and outside the drilled hole, offering double corrosion protection to...

6 advantages of Self-drilling soil nail | Sinorock

Self-drilling soil nail is a method of rock soil reinforcement. It has a full-length thread on its outer surface, coupling can lengthen anchor bar and the disposable drill bit is installed at its front. Because of its special structure, self-drilling soil nail has several advantages: High efficiency: self-drilling soil nail combines drilling, grouting, and anchoring together, which decreases the working procedure and improves working efficiency. Extensive application: self-drilling soil nail is suitable for stratum which is difficult to drill holes, such as weak and broken surrounding rocks, where is difficult to insert soil nail and easy to collapse. After drilling,...

Soil Nailing – An Effective Method of Anchorage

Soil nailing is an effective method of anchorage, soil nails are steel reinforcing members that are installed in a uniform grid pattern and grouted to unify the soil into a cohesive mass creating a soil nail wall. Soil nailing is usually used to stabilize existing slopes or excavations where top-to-bottom construction. It is advantageous compared to other retaining wall systems. When all soil nails within a cross-section are located above the groundwater table, it proves economically attractive and technically feasible by soil nailing. Sinorock is an anchor bolt manufacturer, which produces a variety of rock bolts including self drilling anchor...

Prestressed rock bolt in deep Foundation support

Prestressed rock bolt supporting is a construction method which means to prevent the collapse of the surrounding soil, implanted inside the surrounding soil rock bolt with tension properties and effective anchorage length, and after stretching to make it increasing soil shear strength. Prestressed rock bolt support has the features of convenient construction, construction speed and low construction costs. The prestressed rock bolt support design principle: Rock bolt support should be carried out according to rock soil survey report for design, first should measure according to anchorage soil of rock bolt to determine which soil is suitable anchorage. Second, according to...

Ottawa West Extension tunnel construction in progress

Ottawa and Ontario officials announced October 11 that more than CAD 232M (USD 175.5M) in government funding will go to the Combined Sewage Storage Tunnel (CSST) project. The project includes the construction of two tunnels: an east-west tunnel through the downtown core from LeBreton Flats to New Edinburgh Park, and a north-south tunnel along Kent Street from Catherine Street to existing infrastructure, just behind the Supreme Court of Canada. The tunnels will reduce the frequency of sewage overflows into the Ottawa River during storms, reduce the risk of basement flooding and increase operational flexibility. The Combined Sewage Storage Tunnel is...

Engineering Measures for Landslide Control

Landslide is a kind of natural phenomenon, referring to that soil and rock mass slides down along slope at weak structural plane or belt under gravity effect and influence of river erosion, underground water activity, rain immersion, earthquake, artificial slope cutting, etc. To avid landslide bringing loss and destroy, except planting vegetation, engineering measures are more common. Bypassing landslide or changing lines, adopting tunnel excavation to avoid landslide section. Building surface and underground drainage system to eliminate influence soil body’s shearing strength from water. As for sliding force, building weight reduction, counter pressure and retaining engineering to reach the effect...
