Conventionally, as described above,
When injecting grout, the grout hose 4 for injecting, exhausting, and draining is launched into the concrete structure 1 and the top 1a
Standing at a height of 1 m or more, when the injection-side grout and the discharge-side grout are homogeneous, the discharge-side grout hose is sealed, and the injection-side pressure is maintained at the required pressure, then the injection-side grout hose Is sealed. After that, when the injected and discharged grout reached the height of the hose 4, the filling of the sheath 3 was confirmed. At the same time, he also confirmed the pouring of breathing water. In addition, the amount of grout stored within the height of 1 m of the hose 4 is 12 m when the inner diameter of the hose is 12 m.
When m was set to about 113 cc, this acted as a reserve amount when the grout injection was insufficient or the expansion was insufficient. However, although a relatively transparent material reinforced with a mesh is used for the grout hose 4, when the number of the grout hoses 4 arranged at the tensioned end of the prestressed concrete is large, the grout hose 4 is injected at the time of pouring the grout. A forgotten grout hose may occur. In addition, when the amount of grout to be injected is large, even if it seems to be sufficient at the time of initial grout injection, there may be a shortage of grout injection as the filling progresses into the unfilled voids in the sheath. appear.

Reference numeral 7 denotes both end portions 6b of the grout confirming device 6,
It is a retaining ring for tightening and closely adhering the grout hoses 4a and 4b into which the 6b is fitted. Further, the upper end of the upper portion 4b of the grout hose 4 may be bent in an inverted U shape as in the conventional example (FIG. 3), but when not bent, the grout flows backward and does not flow out of the grout hose 4. In order to do so, or to prevent dust or foreign matter from entering the hose 4 before pouring grout, it is desirable to install the check valve 8. Also, the content of the confirmation device 6 is 2
About 100 to 500 cc is suitable, and the mounting height may be 400 mm or more from the top end 1a.
Compared with the reserve amount of about 113 cc in this case, a reserve amount more than twice as much can be stored, and even if accidentally injecting grout with large breathing, it is possible to sufficiently deal with it. By the way, conventionally, a material with high transparency was used for the grout hose 4 to check the grout injection and discharge. However, according to the present invention, the state of the grout injection can be visually checked with the transparent or translucent grout checking device 6. , The upper and lower hoses 4a. 4b is not necessarily transparent, so that a high-strength material can be freely adopted.

EFFECTS OF THE INVENTION The grout injection and discharge confirmation method and the injection and discharge confirmation device of the present invention have the above-mentioned configurations and functions. It can be easily visually confirmed. Further, even if the number of grout hoses arranged at the tensioned end of the prestressed concrete is large, according to the present confirmation tool, there is no risk of forgetting to inject during grout injection. Further, since the grout injection and discharge confirmation device according to the present invention can store a grout reserve amount which is more than twice as large as that of the conventional grout hose, even if accidentally injecting grout with large breathing or less expansion, it is sufficiently dealt with. It will be possible. In addition, when the amount of grout to be injected is large, even if it seems to be sufficient at the time of initial grout injection, but after that, the grout injection becomes insufficient as the filling progresses into the unfilled void in the sheath. But it can be replenished automatically. Therefore, according to the present invention, the structural strength of the post-tensioning prestressed concrete structure can be maintained safely and reliably for a long period of time.
