Description
(.54) ВОДОПОДПОРНАЯ ПРОБКА ДЛЯ ГИДРОТЕХНИЧЕСКОГО ТУННЕЛЯ С БЕТОННОЙ ОБДЕЛКОЙ(.54) WATER SUPPORT PLUG FOR HYDROTECHNICAL TUNNEL WITH CONCRETE WALL
Изобретение относитс к гидротехническому строительству, в частйости к строительству туннелей дл пропуска строительных расходов.The invention relates to hydraulic construction, in particular to the construction of tunnels to pass construction costs.
При строительстве плотин на горных участках рек на период пропуска ,строительных расходов сооружают временные обводные строительные туннели , которые после окончани срока их эксплуатсщии заделывают бетонными пробками.During the construction of dams in the mountainous sections of the rivers for the period of the passage, the construction costs construct temporary construction bypass tunnels, which, after the expiration of their exploitation, are sealed with concrete traffic jams.
Известна конструкци водоподпорной пробки, включающа секционный корпус и крепежные элементы 11.The known design of a water retaining plug includes a sectional body and fasteners 11.
Недостатком пробки вл етс необходимость выполнени опорных врубов , которые требуют значительных затрат времени и средств.The disadvantage of a cork is the need to perform support cuts, which require a considerable investment of time and money.
Наиболее близкой к изобретению вл етс водоподпорна пробка дл гидротехнического туннел с бетонной обделкой, включающа напорную и безнапорную грани и профильтрационные элементы 2.Closest to the invention is a water retaining plug for a hydraulic tunnel with a concrete lining, including pressure and pressureless edges and filtering elements 2.
Недостатком пробки вл етс необходимость выполнени большого числа крепежных элементов, что св зано с значительными затратами ручного труда. Кроме того, это вызываетThe disadvantage of a cork is the need to make a large number of fasteners, which is associated with significant costs of manual labor. In addition, it causes
необходимость удлинени корпуса пробки .the need to lengthen the cork body.
Целью изобретени вл етс сокращение трудозатрат и упрощение конструкции .The aim of the invention is to reduce labor costs and simplify the design.
Поставленна цель достигаетс тем, что пробка выполнена с дренажным слоем, расположенным в подошве пробки со стороны безнапорной грани, The goal is achieved by the fact that the plug is made with a drainage layer located in the bottom of the plug from the free-flow face,
10 а средн часть напорной грани выполне а с уклоном в сторону напорной части туннел , причем противофильтрационные элементы расположены параллельно напорной грани и концы их за15 деланы в обделку.10 and the middle part of the pressure face is made with a slope towards the pressure part of the tunnel, moreover, the impervious elements are arranged parallel to the pressure face and their ends are closed into the lining.
На фиг. 1 показан участок туннел с пробкой, продольный разрез,- на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.FIG. 1 shows a section of a tunnel with a stopper, a longitudinal section; in FIG. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.
2020
Пробка включает корпус 1, противофильтрационные элементы 2 и дренажный слой 3, выполненный прерывистым с оставлением в корпусе 1 пробки опорных полос 4. Над корпусом The plug includes a housing 1, anti-filtration elements 2 and a drainage layer 3, which is made intermittent, leaving the support strips 4 in the housing 1. Above the housing
