The reuse of building materials becomes an important issue in sustainable engineering. As the technical requirements for civil engineering structures changes with time and life is limited, need new objects meets necessity recycling existing ones. In case steel structures, possibility obvious, also wooden constructions, "burning" solves problem. concrete waste generated mainly as a result demolition reconstruction residential industrial buildings. These types are basically made from crushed...
The purpose of this paper is to report on the field tests for formation a single DR (dynamic replacement) column and its influence surrounding weak soil deposit. has been assessed with piezocone dilatometer measurements, as well by changes in strength deformation parameters obtained from tests. These measurements were carried out during after at varying distances column. have shown that close became weaker formation. As result stiffness found increase over time. was natural state, more...
Abstract Dynamic replacement (DR) is a ground improvement technique that has been used now for almost 50 years. During the formation of DR column crater created which then filled with coarse material and compacted again. The length, diameter shape such cannot be observed directly, makes design execution more troublesome. In article presented are dimensions shapes 18 columns from eight different test fields. They were formed by means pounders various masses (9 or 11.5 Mg) (1.00 1.05 m in...
The paper presents a comparative analysis of the consolidation soil under road embankment reinforced with stone columns. results were obtained from most common analytical and numerical methods applied in driven column dimensioning. approach exploits Terzaghi’s one-dimensional theory Barronʼs three-dimensional theory. calculations reflected particular stages construction various two- systems. geotechnical parameters that crucial for research determined on basis geoengineering documentation,...
W artykule przedstawiono wyniki oceny twardości i pracy lamania spoin po obrobce cieplnej zlączy spawanych zarowytrzymalej stali niskostopowej T24 (7CrMo-VTiB10-10). Wykazano, ze otrzymanie jednocześnie wymaganych wlaściwości plastycznych jest mozliwe jedynie wyzarzaniu w temperaturze co najmniej 700oC. Podjeto rowniez probe wyjaśnienia przyczyn wystepowania niezadowalającej udarności stosunkowo do niskiej wyzarzania. The properties of joints 7CrMoVTiB10-10 (T24) steel after heat treatment...
The dynamic replacement method is used to strengthen the subgrade of objects, usually up 5 6 m thick. After improvement process, acceptance tests in form load testing are carried out. Interpretation test results can cause some difficulties. Dynamic a situation where columns different shapes, loaded with plates diameters smaller than head diameter and vicinity adjacent columns, subjected tests. In order demonstrate influence these factors, spatial model soil strengthened by replacement,...
Abstract The aim of this paper was to find an answer the question about possibility using steel welded mesh in building retaining walls gabion baskets. In light currently used structure solutions, among which double-woven is much more popular, focus put on mesh. A numerical analysis conducted examine behavior and woven subjected various loads results obtained for both types were directly compared. maximal displacement nodes admitted as measurement system (in case undamaged damaged mesh).
Artykuł przedstawia wyniki badań właściwości mieszanek mineralno-asfaltowych wyprodukowanych z dwóch rodzajów destruktu, zawierających asfalt modyfikowany oraz wysokomodyfikowany. Oba rodzaje destruktu pozyskano w warunkach rzeczywistych, a wyprodukowane nich mieszanki nie zawierały dodatku środków odmładzających. Mieszanki doprowadzono do temperatury zagęszczenia wg wymagań krajowych, tak- że poddano dodatkowym procesom starzenia tym temperaturze przekraczającej temperaturę degradacji...
The paper discusses an industrial floor that was constructed on a reactive slag subbase. Five years after completion, the user reported damage caused by displacement. Cracks and scratches were observed in finishing layers, particularly at connection between partition walls floor. Geotechnical surveying investigations carried out to determine cause of damage. revealed presence as subbase layer. Floor displacement measurements taken over four-year period, from November 2019 2023. Despite being...
The dynamic replacement columns are formed by driving a coarse-grained material into soft soil means of repeatable drops pounder.The final shapes the non-cylindrical and depend on subsoil conditions.This paper presents results laboratory study influence thickness displacements backfill aggregate during process.A test box with one acrylic-glass wall was prepared, in which, over load-bearing sand layer, various thicknesses ( = 0.3, 0.4 or 0.5 m) modelled using semi-transparent acrylic...
In the dynamic replacement method (DR) soil is improved by initially dropping a large weight (typically 8-20 t) pounder from significant height up to 25 m. The created crater filled with stronger material (gravel, rubble, stone aggregate, debris), and dropped once or multiple times again. construction of pillars influences parameters adjacent soil. It results energy generated into current practice, these changes are not taken account during design. This paper focuses on overconsolidation...
This paper discusses the failure of a warehouse floor (with an approximate surface area 1.550 m 2 ) inside industrial building with total developed approx. 8.200 along testing and its repair. Over ten-odd years operation building, was found to develop non-uniform settlement maximum depth approximately 150 mm from original level. The completed survey inspections, geotechnical tests FEM studies demonstrated that root cause these events foundation floor, built on subsoil which featured high...
