Description
(54) ОБСАДНАЯ ТРУБА СКВАЖИН(54) WELLPETCHING
Изобретение относитс к устройствам, используемым в строительстве при бетонировании скважин в слабых неустойчивых грунтах.The invention relates to devices used in construction when concreting wells in weak, unstable soils.
Известна обсадна труба, включающа телескопические сектой, содержащие на одном конце муфты с подпрумсиненными упорами 1.A casing is known, including a telescopic sect, which has, at one end, couplings with press-fit lugs 1.
Недостатком известной конструкции вл етс ее сложность и ненадежность в эксплуатации .A disadvantage of the known construction is its complexity and unreliability in operation.
Известно устройство, включающее обсадную трубу, в верхней части которой установлена воронка 2.A device that includes a casing, in the upper part of which is installed a funnel 2.
При бетонировашга скважин бетон через воронку подаетс в трубу, котора при этом извлекаетс .When the wells are concrete, the concrete is fed through a funnel into the pipe, which is then removed.
Недостаток известного устройства заключаетс в том, что при создании скважин большой глубины дл подачи бетона в. извлекаемую трубу необходимо устанавливать подмости или делать обсадную трубу составной, что значительно снижает эффективность бетонировани скважин .A disadvantage of the known device is that when creating wells there is a great depth for feeding concrete into. the recoverable pipe must be installed scaffolding or make casing pipe composite, which significantly reduces the efficiency of concrete wells.
Целью изобретени вл етс повышение производительности бетонировани скважин.The aim of the invention is to improve the performance of concrete wells.
Указанна цель достигаетс тем, что корпус обсадной трубы выполнен с окнами, имеющими крышки.This goal is achieved by the fact that the casing body is made with windows that have covers.
Это позвол ет производить бетонирование скважин непосредственно с поверхности.This allows concreting of wells directly from the surface.
На фиг. 1 изображен общий вид обсадной трубы; на фиг. 2 - сечение А-А,фиг. 1; на фиг. 3 - сечение Б-Б фиг. 1.FIG. 1 shows a general view of the casing; in fig. 2 is a section A-A, FIG. one; in fig. 3 is a section BB of FIG. one.
Обсадна труба 1 выполнена с окнами 2 по длине, которые имеют крыщки 3.Casing pipe 1 is made with windows 2 in length, which have a cover 3.
Перед погружением обсадной трубы в скважину окна 2 закрьшаютс крыщками 3. При бетонировании скважины по мере заполнени ее бетоном обсадна труба извлекаетс из скважины, крышки 3 открьшаютс , и бетон подаетс в скважину через окна 2 непосредственно с поверхности земли.Before the casing is immersed in the borehole, the windows 2 are crowned with lids 3. When the concrete is concreted as it is filled with concrete, the casing pipe is removed from the borehole, the lids 3 open and the concrete is fed into the borehole through the windows 2 directly from the ground surface.
