Polymer Injection Groutings in hydraulic Engineering Dam Structures


download

Hydraulic earth dams, e. g. dykes, often possess inadequate or even no waterproofing so that seepage can occur possibly affecting the stability during impounding. Within the scope of a R+D project, a Low Pressure Injection (LPI) method for soft grounds was developed, capable of achieving a higher sealing level through the application of acrylate gels. The focus is directed at eliminating leaks in seals, the connecting areas between the earth and massive structure as well as crossings. Mixing the granular structure with the injection grout substantially improves the shear and uniaxial compressive strength and significantly reduces the hydraulic conductivity in the grouted soil matrix.

Micropiling in Urban Infrastructure: Advantages, Experience and Challenges


download

Increasing urbanization places high demands on urban infrastructure. New infrastructure is required and existing facilities have to be extended. Intraurban interventions causing the least possible disturbance are frequently carried out in densely populated and built-up areas within a tight timeframe. Micropiling can contribute towards satisfying the challenges. This article presents infrastructure projects using self-drilling micropiles in four areas: public services, transportation, telecommunications and heritage conservation. The special requirements are briefly described, and the geotechnical solutions presented. Finally, a summary of micropiling in urban areas is given.

Blast Performance Improvement using Stemming Plugs at Limestone Quarries in the Salt Range of Pakistan


download

Stemming inside a blast hole plays a vital role for optimizing blast results. Blasting may result in issues like flyrock and an unnecessary number of boulders. At some sites, blasted material does not move laterally to generate good throw with blasting. As a solution to the existing problems, newly developed stemming plugs have been tested on-site to check their performance. This paper presents blasting tests using stemming plugs on limestone quarries in the Salt Range of Pakistan. The results demonstrate better fragmentation with a reduced number of boulders and better throw of blasted material. The productivity of loading operations increases and the overall operational costs at quarries can be reduced.
