Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] A grouting method in separate bins, characterized in that: comprising the following steps;

[0021] 1. Material preparation:

[0022] (1) 20kg bags of CGMJM-Ⅵ high-strength slurry have an initial setting time of 3 hours and 40 minutes at 20°C and 2 hours at 35°C. The performance parameter table of CGMJM-Ⅵ high-strength slurry is attached. figure 1 .

[0023] (2) Drinking water. Drinking water should be used for mixing mortar. When using other water sources, it should meet the requirements of the "Concrete Mixing Water Standard" (JGJ63).

[0024] 2. Preparation of construction machinery and tools.

[0025] (1) 100 kg floor scale (for weighing water and materials);

[0026] (2) Mercury thermometers and surface thermometers;

[0027] (3) 200ml measuring cylinder;

[0028] (4) Mixing barrel with a volume of 200-300L;

[002...

Abstract

The invention relates to a separate bin grouting method. The separate bin grouting method includes the following steps that firstly, CGMJM-VI high-strength slurry is poured into a stirring cylinder; secondly, before pointing, the surface of a component and the surface of concrete should be cleaned up; thirdly, one end of a rubber hose with the diameter being 20 mm is gradually crammed into a seam in the bottom of the component along the outer side of the seam of the bottom of the prefabricated component; fourthly, the component and the concrete floor slab surface are wetted firstly before the cording seam is pointed through pointing trowels; fifthly, the rubber hose crammed into the seam of the bottom of the prefabricated component is pulled out slowly from the other end after the cording seam pointing is completed; and sixthly, after the rubber hose is pulled out, a taking-out opening is blocked tightly with a small ball of cording seam mortar. The separate bin grounding method is a construction process for rebar sleeve connection grouting component bottom seam blocking and has the beneficial effects that construction operation is easy, convenient and fast, and energy saving and environment protection are achieved.

Description

technical field [0001] The invention relates to a grouting method in separate bins. Background technique [0002] In the existing grouting construction process at the bottom of structural parts, wooden formwork and sealing strips are generally used to seal the grouting gaps at the bottom of prefabricated components, and there is no guarantee that the grouting of larger components can be completed at one time. In addition, there are problems that the grouting gap at the bottom of the prefabricated component is not tightly closed, and mortar leakage occurs during component grouting, and there is no guarantee that the grouting of larger components can be completed at one time. Therefore the above method is not suitable for use in the modern construction process. [0003] With the continuous development of modern society, industrialized prefabricated structures have gradually become the inevitable development trend of modern architecture. Therefore be badly in need of a kind o...
