Soils investigations in sand and gravel deposit in Šilavotas eldership, Prienai district

Gamtinės birios naudingosios iškasenos, esančios ţemėje, gali būti naudojamos įvairiose ūkio šakose, kaip ţaliava gaminant įvairius gaminius, tame tarpe ir statybines medţiagas. Pagal vertę ir gavybos bei naudojimo kiekį svarbiausios pasaulyje naudingosios iškasenos statybos pramonei yra ţvyras, smėlis, molis, skalda, klintis cemento pramonei ir kt. Lietuva nėra turtinga gamtiniais išteklias. Daugiausia eksploatuojami statybinių ţaliavų vietinių išteklių šaltiniai, kurių iškasenos naudojamos statiniams statyti, tiesti susisiekimo komunikacijas, inţinerinius tinklus, kaip ţaliava statybinėms medţiagoms gaminti. Šis baigiamasis darbas skirtas Prienų rajone Šilavoto seniūnijoje esančio smėlio ir ţvyro telkinio gruntų savybių tyrimui, galimam grunto panaudojimui statybose. Darbe pateiktos grunto savybių nustatymo laboratoriniais darbais metodikos, būtinos ţinios numatytiems uţdaviniams įgyvendinti. Laboratoriniais tyrimais nustatytos pagrindinės grunto fizikinės savybės, atliktas granuliometrinės sudėties tyrimas, pateikti grunto panaudojimo statybose pasiūlymai. Laboratoriniai tyrimai atlikti pagal galiojančias metodikas. Bandymų metu įsigilinta į naudojamų metodų esmę. Visi laboratoriniai bandymai atlikti pagal galiojančius standartus. Šio baigiamojo darbo tikslas yra nustatyti smėlio ir ţvyro telkinio gruntų pagrindinius fizikinius parametrus ir numatyti jų panaudojimo galimybes statyboje.Natural bulk minerals lying in the depths of the earth, can be used in a variety of industries as a raw material for the production of a variety of products, including construction materials. In terms of value and extraction and use, the world's most important minerals for the construction industry are gravel, sand, clay, crushed stone, limestone for the cement industry, and so on. Lithuania is not rich in natural resources. Sources of local resources of construction raw materials are mainly exploited, the minerals of which are used for the construction of buildings, construction of communications, engineering networks as a raw material for the production of construction materials. This final work is for to the study of the soil properties of the sand and gravel deposit in Šilavotas eldership in Prienai district and the possible use of the soil in construction. The paper presents methodologies for determining soil properties by laboratory work, knowledge necessary for the implementation of the planned tasks. The main physical properties of the soil were determined by laboratory tests, the granulometric composition study was performed, and proposals for the use of soil in construction were presented. Laboratory tests were performed according to current methodologies. During the tests, the essence of the methods used was studied. All laboratory tests were performed according to current standards. The aim of this final work is to determine the main physical parameters of sand and gravel soil and to predict the possibilities of their use in construction.Natural bulk minerals lying in the depths of the earth, can be used in a variety of industries as a raw material for the production of a variety of products, including construction materials.
