Schaft shinking

1. Introduction, characteristics of complex conditions (natural, human, technical and organizational) principles, structure and outline implementation procedures for underground construction in difficult conditions. 2. Realization of underground works under the protection of compressed air - kesonování. Freezing third. Fourth needling driven shoring, excavation contour, shielding, embossed. 5th microtunnelling, horizontal drilling, trenchless technology. 6th backfilling of underground works, sluicing underground works. 7. Environmental impacts of subsurface underground workings, their prognosis and prevention. 8. The technology is sinking. The flume construction site. 9th Reinforces constructions, material parameters. 10. Classical digging pits and manholes. 11th deepening, broadening jam. Digging blind jam. 12th Drilling jam. 13. Special dredging technology. 14th expert presentation - case histories. Exercise: 1. Preparation and submission of the study implementation of the construction works in horizontal underground complex nature of technical conditions (individual for each student). Speeches and information on a given topic on exercises. 2. Complex technology design excavation conventional technology in simplified geotechnical conditions: - design type and parameters with welded construction - technological procedure of blasting during excavation - fixing machinery and calculation of technological times major operation with the digging cycle (drilling, blasting, was cleared of muck, reinforcing and equipping pit) - auxiliary operations (separate ventilation, air management, water pumping). Programs: 1. Study the construction of a horizontal underground workings mined in difficult geotechnical conditions. 2. Proposal traditional technology excavation or manholes. Multimedia aids used for teaching: Expert commentary on the course is supported by audio-visual means. Standard, constantly used tool is the overhead projector for projection transparent originals (film). Teaching complements casual presentation video recordings, with the aim of documenting lectured problems real facts.
