1. 1. Jämförelse mellan grundläggningsmetoder för lera med begränsat djup

   Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

   Författare :Isak Ekström; Taulant Lutfiu; [2023]
   Nyckelord :Short piles; land excavation; environment; soil replacement; Grundläggningsmetoder; kostnad; korta pålar; miljö; utskiftning;

   Sammanfattning : This thesis compares foundation methods for buildings on low-strength, limited-depth soil. The study focuses on soil replacement and piling, specifically concrete and steel piles. The studyaims to answer the key questions about the possibility to use short piles on limited depth, cost-efficiency, and environmental impact of these methods. LÄS MER

3. 2. Påldrivning: Jämförelse mellan luft- och vattendriven borrning : En utredning av jämförelser avseende slitage, logistik och driftkostnader

   Kandidat-uppsats, KTH/Byggteknik och design

   Författare :Andreas Bengtsson; Pierre Bodin; [2022]
   Nyckelord :: percussion hammer; pilot; DTH; pile driving; wear; drill rig; casing; piston; check valve; water-handling; sedimentation; : sänkhammare; pilot; DTH; pålning; slitage; borrigg; foderrör; kolv; backventil; vattenhantering; sedimentering;

   Sammanfattning : Skanska Grundläggning in Region Special wishes to gain an increased understanding of the extent to which it differs in the wear of percussion hammers and pilot drill crowns, depending on which driving medium is used in down-the-hole drilling, as well as logistical and economic aspects depending on the chosen method. Down-the-hole drilling means that the hammer works down in the borehole and forms one of the components at the far end of the drill string together with a drill bit. LÄS MER

4. 3. Geotechnical reinforcement work for foundation of extending an existing residential building

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Malin Karlbom; Lovisa Hallman; [2020]
   Nyckelord :Geotechnical reinforcement work of foundation; drilled piles; steel piles; superstructure; extension of wood; Grundförstärkning; borrade pålar; stålpålar; våningspåbyggnad; påbyggnation av trä;

   Sammanfattning : The last hundreds of years there has been a land elevation that causes an increased distance between the groundwater level and the buildings founded on wooden piles. When wooden piles are exposed to air, rot fungus occurs which causes the pile to lose its bearing capacity. LÄS MER

5. 4. Parametric Optimization of Foundation Improvements with RC Slabs on Piles

   Master-uppsats, KTH/Betongbyggnad

   Författare :Oliver Kling; Nils Dahlman; [2019]
   Nyckelord :Parametric Design; Parametric Optimization; Concrete Structures; Reinforced Concrete; Foundation Improvements;

   Sammanfattning : Parametric design has proven to be a powerful tool for structural engineers to find innovativesolutions to complex problems more effectively compared to conventional methods. Theflexibility off parametric design is immense since all types of structures depend on a range ofparameters that can be isolated, controlled and altered. LÄS MER

7. 5. Pore pressures and settlements generated from two different pile drilling methods

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Rasmus Ahlund; Oscar Ögren; [2016]
   Nyckelord :DTH; bored piles; pore pressure; settlements; over-drilling; sänkhammarborrning; borrade pålar; portryck; sättningar; överborrning;

   Sammanfattning : For piling works in sensitive soil, especially in inner city projects, it is essential to be aware of the available methods and to choose the most suitable method to minimize the risk of damaging existing buildings or endanger the workers at the construction site. Down-the-hole drilling of piles is a relatively safe method and can be separated into drilling with air powered hammers and water powered hammers. LÄS MER
