Slurry surface detection and slurry supplementing method for grouting sleeve

Abstract

The invention relates to a slurry surface detection and slurry supplementing method for a grouting sleeve. The method comprises the following steps of (1) assembling prefabricated parts; mounting a slurry surface detection and slurry supplementing device; (3) performing grouting; (4) detecting the inner grouting surface of the grouting sleeve: observing the height change of the inner slurry surface of a display tube, until slurry is solidified after grouting is completed, and after it is observed that the slurry level of the display tube declines or the height of the inner slurry surface of the display tube is lower than a preset height, performing the step (5); and (5) performing slurry supplementing: connecting a grouting device with a slurry supplementing tube, and performing the slurrysupplementing on the interior of the grouting sleeve through a slurry supplementing device. The slurry height and the slurry height change condition in the grouting sleeve can be observed, so that real-time monitoring data is provided for ensuring the grouting fullness; and when the slurry is lost, the slurry supplementing is performed in time, so that the fullness of the slurry in the grouting sleeve is ensured to meet the quality requirement. According to the method, the operation is convenient, the reliability is high, and the connection quality of the grouting sleeve can be ensured.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a grout surface detection and grout replenishment method of a grouting sleeve. Background technique [0002] In the construction of prefabricated building structures, the connection between prefabricated columns, beams and slabs is usually connected by sleeves; after the on-site prefabricated parts are hoisted, the next construction process is grouting, and the upper and lower walls, the upper sleeve and the lower part Insert rebar. Before grouting, it is necessary to seal the upper and lower wall panels (frame columns). Generally, special seat slurry is used, also known as building warehouse. After the warehouse is built, inject grout through the grouting hole of the sleeve until the warehouse and the sleeve are completely filled with slurry. When the grout is solidified and meets the strength requirements, the on-site construction of this process wil...

AI Technical Summary

Problems solved by technology

But at this time, the fluidity of the slurry decreases, and the slurry replenishment effect is poor

Even if the grout is replenished from the grouting port of the sleeve at this time, the situation after grouting cannot be observed, making the effect of grouting unreliable
