Hole mainly uses circular ring shape steel plate to be close to the borehole wall and reinforce using setscrew, and rubber water-proof circle is arranged in the borehole wall and circular ring shape
Between steel plate, for such antipriming for minor radius arc well, water-stagnating effect is poor, is not able to satisfy sealing requirement.
Summary of the invention
In order to which the water-stagnating effect for solving jacking construction hole is poor, the problems such as not being able to satisfy sealing requirement, the utility model is mentioned
A kind of arc well push pipe water stop device for opening is gone out.
The purpose of this utility model is achieved through the following technical solutions: a kind of arc well push pipe water stop device for opening, described
Push pipe penetrates into arc well from hole, and fixed plate is arranged on the hole, and fixed plate is fixed on the borehole wall of arc well, fixed
Perforation is set on plate, and push pipe sequentially passes through hole and perforation is placed in arc well, and fill area, filling is arranged in the side of fixed plate
Between fixed plate and arc well, rubber ring, internal diameter and the outer diameter of push pipe of rubber ring etc. are installed in the other side of fixed plate in area
Greatly, rubber ring sleeve seals hole on push pipe.
Preferably, a kind of arc well push pipe water stop device for opening, the rubber ring are clipped in fixed plate and flag
Between, screw bolt passes fixed plate, rubber ring and flag are simultaneously fixed with nut.
Preferably, a kind of arc well push pipe water stop device for opening, the interior fill area is accelerated cement mortar, speed
Condensate cement mortar is filled between fixed plate and the borehole wall of arc well.
Preferably, preformed hole is arranged in the lower section of a kind of arc well push pipe water stop device for opening, the fixed plate, when
Accelerated cement mortar, which reaches, drains pressure release by preformed hole before intensity, passes through preformed hole ejection for water plugging after the completion of jacking construction.
Preferably, a kind of arc well push pipe water stop device for opening, the fixed plate are square plate, square plate
Four sides be fixed by screws on the borehole wall of arc well respectively.
Compared with prior art, the utility model has following the utility model has the advantages that the utility model is by by rubber ring sleeve
On push pipe, the effect at sealing hole is realized, efficiently solves the problems, such as hole sealing, this device can not only be directed to various shapes
The push pipe hole sealing of shape, size, it is especially prominent especially for the minor radius arc well effect of rich groundwater sandy soil layer.
The utility model structure is simple, strong applicability, effectively increases sealing speed and sealing anti-seepage effect.
Detailed description of the invention
