Abstract
The utility model provides a non-adhesive pre-stressed steel sleeve concrete pressure pipe used to transport or store liquid medium, which comprises a concrete pipe body (1), the inside of the concrete pipe body (1) is provided with a steel sleeve (2), the inside of the pipe body (1) outside the steel sleeve (2) is provided with a non-adhesive pre-stressed steel wringing wire ring (3), the two ends of the non-adhesive pre-stressed steel wringing wire ring (3) is fixedly arranged on the anchorage port (4) inside the pipe body (1), the improved part is that the inner wall of the steel sleeve (2) inside the pipe body (1) is provided with a stud (5) welded on the inner wall of the steel sleeve (2). The utility model has advantages that the concrete layer of the steel sleeve (2) and the inner wall of the pipe body (1) do not separate.
Description
The utility model relates to and a kind ofly is used to carry or the concrete pressure pipe, particularly prestressing without bondn steel bushing concrete pressure pipe of fluid storage medium.
In known technology, a kind of prestressing without bondn steel bushing concrete pressure pipe comparatively close with the utility model, it comprises concrete tube body, has a steel bushing in the body, has the un-bonded prestressed steel strand ring in the body outside steel bushing, the two ends of steel strand ring are fixed on the interior ground tackle of body, have the reinforcing bar reinforced layer on the body in steel bushing.The advantage that this pressure tube has withstand voltage height, do not leak, it is not wanted deficiency and is that the concrete layer in the steel bushing separates with steel bushing easily, the dielectric corrosion steel bushing in the pipe; The deficiency of next is that the steel pipe of bellmouth inwall and socket outer wall does not have concrete cover, is subjected to the corrosion of medium easily.
The purpose of this utility model is to provide a kind of prestressing without bondn steel bushing concrete pressure pipe, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of prestressing without bondn steel bushing concrete pressure pipe, it comprises concrete tube body (1), has steel bushing (2) in the concrete tube body (1), has un-bonded prestressed steel strand ring (3) in the body (1) outside steel cylinder (2), the two ends of un-bonded prestressed steel strand ring (3) are fixed on the un-bonded prestressed steel strand ground tackle (4) on the tube wall of body (1), and its improvements are to have the peg (5) that is welded on steel bushing (2) inwall on the inwall of the steel bushing (2) in body (1).
The utility model prestressing without bondn steel bushing concrete pressure pipe can be that the end at body (1) has the bellmouth (6) that is used for connecting between the tube and tube, has socket (7) at the other end of body (1).
The utility model prestressing without bondn steel bushing concrete pressure pipe can be that the steel pipe and the steel bushing (2) of the bellmouth (6) of body (1) pipe end is one, and the inner and outer wall of bellmouth (6) and socket (7) has concrete cover.
The prestressing without bondn steel bushing concrete pressure pipe that the utility model provides, owing to concrete tube body (1) in, have the peg (5) that is welded on steel bushing (2) inwall on the inwall of steel bushing (2), has the advantage that the interior concrete layer of steel bushing and steel bushing do not separate.
Fig. 1: the master of a kind of structure of the utility model looks sectional view.
The A-A sectional view of Fig. 2: Fig. 1.
The utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.
Embodiment 1, Fig. 1 and Fig. 2 have provided a kind of concrete structure of the utility model, consult Fig. 1 and Fig. 2, a kind of prestressing without bondn steel bushing concrete pressure pipe, it comprises concrete tube body (1), has a steel bushing (2) in the concrete tube body (1), has un-bonded prestressed steel strand ring (3) in the body (1) outside steel bushing (2), the two ends of un-bonded prestressed steel strand ring (3) are fixed on the un-bonded prestressed steel strand ground tackle (4) on the tube wall of body (1), have the peg (5) that is welded on steel bushing (2) inwall on steel bushing (2) inwall in body (1).End at body (1) has the bellmouth (6) that is used for connecting between the tube and tube, has socket (7) at the other end of body (1).Steel pipe and steel bushing (2) in the bellmouth (6) of body (1) pipe end are one, and the inner and outer wall of bellmouth (6) and socket (7) has concrete cover.Pass ground tackle (4) at the two ends of prefabricated process un-bonded prestressed steel strand ring in advance on tube wall, treat that concrete tube wall solidifies after, the two ends of stretch-draw steel strand ring (3) also are fixed on the ground tackle (4).Prestressing without bondn steel wire, ground tackle and peg adopt is special purpose parts in the known technology.Peg (5) on steel bushing (2) inwall plays steel bushing (2) and does not separate effect with the coagulating layer of body (1) inwall; steel pipe on the bellmouth (6) and steel bushing (2) are the ability of bearing pressure that body has increased bellmouth (6), and the inner and outer wall of bellmouth (6) and socket (7) has the corrosion resistant ability that the coagulation protective layer has increased jointing.The pressure tube of this structure can be provided with rubber seal between bellmouth and socket, adopt between the tube and tube to flexibly connect.
Claims (3)
1, a kind of prestressing without bondn steel bushing concrete pressure pipe, it comprises concrete tube body (1), has a steel bushing (2) in the concrete tube body (1), has un-bonded prestressed steel strand ring (3) in the body (1) outside steel bushing (2), the two ends of prestressing without bondn steel twist line ring (3) are fixed on the un-bonded prestressed steel strand ground tackle (4) on the tube wall of body (1), it is characterized in that having the peg (5) that is welded on steel bushing (2) inwall on steel bushing (2) inwall in body (1).
2, prestressing without bondn steel bushing concrete pressure pipe according to claim 1 is characterized in that having the bellmouth (6) that is used for connecting between the tube and tube at an end of body (1), has socket (7) at the other end of body (1).
