Abstract
The utility model relates to a spigot and a socket steel rings for a prestressed steel tube concrete pipe, which is characterized in that the spigot steel ring is formed into a moving structure with two grooves, and a pressure testing hole and a closing rotary plug are arranged between the two grooves. Because the utility model can visually carry out the water tightness test of pipe joints, the use is convenient and reliable.
Description
The utility model relates to the docking facilities of prestressed concrete pipe, and specifically a kind of socket steel ring that is welded on steel cylinder two ends in the prestressed concrete pipe tube core comprises bellmouth steel loop and socket steel ring.
It is a kind of heavy caliber that is applicable to that pre-stress steel cylinder coagulates native pipe, senior engineer presses the high-quality tubing of waterline, the bellmouth and the socket steel ring that are welded in tubing steel cylinder two ends connect into pipeline with the single tube material, the socket steel ring of prior art is single groove structure, establish seal ring in the groove, play the sealing joint effect, this structure is difficult to carry out the waterproof test of single joint, and can only useful clearance gauge detection method check whether seal ring puts in place, promptly in pipe, straight touch gauge is stretched into the joint socket matching gap outward, and along garden week the aspect move the rubber seal situation in place of checking, the both complicated trouble of this method is not directly to detect for the water tightness of joint yet.
The purpose of this utility model provides a kind of easy to detect reliable, can check intuitively whether piping erection is correct, confirms that more whether sealing puts in place, promptly directly detects the joint socket steel loop of sealing joint performance.
The utility model comprises bellmouth steel loop and the socket steel ring that is welded on Prestressed concrete cylinder pipe tube core steel cylinder two ends, the bellmouth steel loop front end outside of prior art only has aprons slot one, of the present utility model being characterized as also has additional another road aprons slot on the bellmouth steel loop, be dual-slot structure, have a pressure testing hole between two grooves, be provided with the sealing cock in this pressure testing hole.
Because socket ring of the present utility model is provided with the twice aprons slot, form an annulus between two aprons slots, and have a pressure testing hole, use the cock jam-pack at ordinary times, during test, unclamp cock, to annulus injecting compressed air or water, under authorized pressure, carry out the water-stop test of interface from the pressure testing hole.The pipe laying person of having can check intuitively when each pipe is installed whether the pipe installation is correct, confirms more whether sealer puts in place, checks very convenient reliable.
Accompanying drawing 1 is the axial sectional view of the utility model socket steel ring.
Accompanying drawing 2 is the axial sectional view of the utility model bellmouth steel loop.
Accompanying drawing 3 uses coupled condition figure for the utility model.
See accompanying drawing, 1 is socket steel ring, the bellmouth steel loop 2 front ends outsides have aprons slot 4 and aprons slot 4 ', have a pressure testing hole 3 between two aprons slots, can be provided with in the pressure testing hole 3 cock 3 '.Referring to accompanying drawing 3, joint socket steel loop of the present utility model is welded on the two ends of Prestressed concrete cylinder pipe tube core steel cylinder 5 respectively, 6 is concrete layer, glue: ring recess 4 and aprons slot 4 ' interior branch is placed sealing than 4a and seal ring 4a ', the socket steel ring of the bellmouth steel loop of one pipe joint spare, one end and an end of another pipe joint spare socket joint (as shown in Figure 3) mutually during installation.
Claims (1)
1, a kind of high efficient prestress cylinder concrete pipe joint socket steel loop, comprise that there is the socket steel ring 1 of aprons slot 4 in bellmouth steel loop 2 and the front end outside, the front end outside that it is characterized by bellmouth steel loop 2 also be provided with aprons slot 4 ', aprons slot 4 and aprons slot 4 ' be provided with pressure testing hole 3 and cock 3 '.
