Description

PC grouting sleeve slurry supplementing device

Technical Field

The utility model relates to the technical field of grouting, in particular to a PC grouting sleeve grouting supplementing device.

Background

As practitioners in the construction industry decrease, and environmental requirements increase, there are increasing numbers of fabricated structures (PC structures). The quality of the full grouting sleeve or the half grouting sleeve of the vertical component of the assembly type (PC) structure is a key point for ensuring the connection of the vertical component, and is a key point for ensuring the structural safety, but in the construction process, the grouting sleeve is inevitably not full due to leakage of the grouted slurry caused by the untight sealing bin or other reasons, so that the structural safety is affected. The lower grouting hole of the grouted sleeve is blocked, the sleeve which is not full in grouting can only be subjected to grouting supplement from the upper grouting hole, the sleeve is influenced by air pressure and the like, and the simple grouting supplement cannot ensure that the slurry effectively enters the sleeve, so that the connection quality of vertical components cannot be ensured.

The assembly structure (PC structure) is constructed, the connection quality of PC components is related to the structural installation of the whole building, and the connection of PC components is totally connected by a full grouting sleeve or a half grouting sleeve, and grouting of the grouting sleeve is performed on a construction site manually by workers. Before primary grouting, the full grouting sleeve or the half grouting sleeve is provided with two holes, slurry is injected from the lower hole during grouting, and after the slurry overflows from the upper hole, the slurry is regarded as full, and then the hole is plugged by a plug to prevent the slurry from flowing out.

The condition of insufficient slurry in the grouting sleeve cannot be avoided due to misoperation of workers, slurry leakage of a bottom bin or other reasons. Because the slurry is not full, the design connection strength requirement cannot be met, and the potential safety hazard of the structure is great. When the grouting sleeve is not full after the primary grouting is finished, the holes at the lower part of the full grouting sleeve or the half grouting sleeve are blocked, and the upper holes cannot be used for grouting.

At present, most of the grouting adopts a grouting device to directly grouting through the upper hole of the grouting sleeve. The greatest disadvantage of this mode of use is: the grouting sleeve is small in size, the diameter of the hole at the upper part is only 10mm, and when grouting is directly performed inwards from the hole through the grouting device, the grouting sleeve is a closed space and is influenced by air pressure, so that the grouting material cannot enter the grouting sleeve. If forced into, the air expands as the injector is removed, and the slurry is forced out of the sleeve.
