Abstract

U ovom radu opisan je presjek radova koji su izvedeni na području studentskog kampusa u Varaždinu. Poznavanje teorijske osnove o svojstvima tekućine i značajkama poroznog medija kao što su struktura, tekstura i poroznost te poznavanje općih zakona gibanja podzemnih vode ključne su za razumijevanje hidrogeoloških parametara vodonosnika. Vodonosnik se definira kao porozni medij koji prima, pronosi i daje vodu. Iako se voda nalazi svugdje oko nas, ne možemo do nje doći lako, osim ako se ne radi o površinskim vodama. Radi dobivanja vode iz vodonosnika grade se zdenci, hidrotehničke građevine pomoću kojih crpimo podzemnu vodu. Zdenci na području studentskog kampusa izrađeni su rotacijskom metodom bušenja uz jezgrovanje. Nakon bušenja slijedi proces šljunčanja, tamponiranja, osiguravanja i ugradnje crpke. Ključan proces u dovođenju zdenca u završnu fazu jest osvajanje zdenca koje za cilj ima čišćenje filtra, omotača uključujući šljunčani zasip i samu okolinu zdenca. Pokusno crpljenje se obavlja radi određivanja parametara vodonosnika i zdenca, a same metode pokusnog crpljenja ovise o tipu vodonosnika. Rad daje postupak i rješenja u određivanju hidrogeoloških parametara vodonosnika i parametara zdenca te opisuje utjecaj zdenaca na okoliš tijekom crpljenja podzemne vode stalnom količinom za potrebe studentskog kampusa.

Abstract (english)

This paper describes a cross-section of works performed in the student campus in Varaždin. Knowledge of the theoretical basis of fluid properties and porous medium characteristics such as structure, texture and porosity and also knowledge of the general laws of groundwater movement are key to understanding the hydrogeological parameters of aquifers. An aquifer is defined as a porous medium that receives, transports, and delivers water. Although water is all around us, it cannot be reached easily except in the case of surface water. In order to obtain water from aquifers, wells are built, hydrotechnical structures with which we pump groundwater. Wells in the student campus area were made by the use of rotary core drilling technology. Drilling is followed by the process of graveling, tamponing, securing and installing the pump. A key process in bringing the well to the final stage is the process of cleaning the well which aims to clean the filter, casing as well as the gravel backfill and the area surrounding the well. Test pumping is performed to determine the parameters of the aquifer and the well, and the methods of testing depend on the type of aquifer. The paper provides procedures and solutions in determining the hydrogeological parameters of aquifers and well parameters and describes the impact of wells on the surrounding environment during the pumping of groundwater in a constant amount for the needs of the student campus.
