Abstract
Inventia se refera la un procedeu si un dispozitiv pentru realizarea unor cintre de beton armat monolit, necesare sustinerii galeriilor si tunelelor aplicat în zonele de roca slaba în locul sustinerii cu cinte metalice nerecuperabile. Procedeul pentru tralizarea cintrelor din beton armat monolit necesare sustinerii galeriilor si tunelelor dupa excavare se monteaza un dispozitiv adaptabil la conturul neregulat al golului excavat, care preia imediat presiunea muntelui, se completeaza cu cofraje peretii laterali ai dispozitivului se toarna în interiorul dispozitivului un cintru din beton armat care dupa întarirea si demontarea dispozitivului preia functia de sustinere a galeriei. Dispozitivul de sustinere este alcatuit din elemente de cintru metalic superior si inferior cu profile U prevazute cu flanse de asmablare gauri pentru trecerea unor ancore nervuri laterale si butoane de strîngere din casetele de rezemare pe roca de dimensiuni variabile cu nervuri pe peretii laterali si suruburi pentru fixarea cofrajelor, din cofraje metalice si console de protectie a casetelor la explozie. Dispozitivul de extragere a casetelor si a elementelor de cintru este alcatuit dintr-un jug cu capete filetate si piulite si mandrine cu gheara care prin însurubarea piulitelor intra sub niste placute de rigidizare a unor casete respectiv în gaurile placilor de pe cintre, desprinderea casetelor realizîndu-se prin actionarea unor piulite de fixare a acestora, iar a elementelor de cintru prin actionarea unor piulite a butoanelor de ancoraj.The invention relates to a process and a device for making monolith reinforced concrete cavities, necessary to support the galleries and tunnels applied in the weak rock areas instead of supporting with non-recoverable metallic rods. The process for the cessation of monolith reinforced concrete reinforcements to support the galleries and tunnels after excavation mounts a adaptable device to the irregular contour of the excavated hole, which immediately takes over the pressure of the mountain, completes with formworks The side walls of the device pour inside the device a concrete cake which after strengthening and dismantling of the device takes over the function of supporting the gallery. The support device consists of upper and lower metal cnc elements with U profiles provided with flanges for assembling holes for passage of anchors lateral ribs and clamping knobs from the rock-bearing variable rocks with ribs on the side walls and screws for fixing formworks, metal formworks and explosion cassette protection brackets. The device for extracting the cassettes and the cintar elements consists of a yoke with threaded ends and nuts and clamps with the claw which, by screwing the nuts, enters under some tamping plates of the cassettes, respectively in the holes of the plates on the grooves, the detachment of the cassettes, by the action of fixing nuts and of the knuckles by the action of nuts of the anchor buttons.
