The reinforcing bar of prestressed concrete well casing of the prior art is by reinforcing bar, stirrup, support annulus, is welded on the welding tire.Since problems of welded quality, reinforcing bar not prison welding, postwelding reinforcing bar pulling force inequality.Have the people to propose Chinese patent 200720101772.X at this problem and solve, welding is inhomogeneous but this kind drainage well casing can not fundamentally solve between well casing and the well casing counterpart, the problem that the well casing quality of connection is not high; Traditional well head butt joint need be carried a well casing by crane or manpower, another well casing is lifted on the last well casing again, two mouths of pipe is aimed at welded; Doing like this wastes time and energy, and can not guarantee the well head welding quality, metals run out easily; Therefore, need to propose a kind of novel prestressed concrete well casing to address the above problem.
Summary of the invention
The novel purpose of this reality provides a kind of prestressed concrete well casing, this concrete well is provided with to hang on the mouth of pipe or body fastens the hole, this is hung and fastens the hole and can improve welding quality between two concrete wells, improves the butt joint installation and the welding efficiency of the concrete well mouth of pipe.
The purpose of this utility model is achieved in that a kind of prestressed concrete well casing, comprise a body, described body two ends are provided with the well casing connection mouth, this well casing connection mouth inwall is provided with hangs the muscle ring, bury Framework Of Steel Reinforcement underground in the described body, this Framework Of Steel Reinforcement constitutes described longitudinal prestressing reinforcing bar two ends and the anchor connection of described extension muscle ring by the steel hoop of the longitudinal prestressing reinforcing bar of well casing connection mouth about the tension and order setting longitudinally; The packing of described body is a concrete; Described concrete well top is provided with at least three and hangs keyhole, and described to hang keyhole in the same plane.
Compared with the prior art the utility model has following advantage:
1, because the utility model is provided with on body and hangs keyhole, and the dismountable technology of plug-in mounting is hung and fastened in this hangs keyhole, when carrying out two well casings to the dress welding operation, guarantee that well casing steadily is placed on the well head, convenient to the dress operation, time saving and energy saving, improved welding quality effectively.
2,, can realize two well casings fast to dress, and can improve welding quality because the utility model is provided with butt plate on body top.
3, because the utility model is provided with sealed groove in the concrete well upper and lower, can prevent the race slurry phenomenon in course of working, improve the smooth quality of well casing port.
