& The following requirements should be met during grouting construction: ). The grout should be poured from one side until it overflows from the other side to facilitate the discharge of the air between the equipment base and the concrete foundation and to enrich the grouting. It should not be carried out from four sides at the same time. Grouting.
). After grouting starts, it must be carried out continuously without interruption, and the grouting time should be shortened as much as possible.
). It is not advisable to vibrate during the grouting process. If necessary, bamboo slats, etc. can be used for pulling and diversion.
). The thickness of the grouting layer should not exceed each time.
). Grouting for longer equipment or track foundations should be carried out in sections. The length of each section is appropriate.
). If bleeding is found on the surface during the grouting process, a small amount of dry material can be spread to absorb the water.
) When grouting the foundation of equipment whose grouting layer is thicker than the large volume, you can add stones according to the total ratio: when mixing the grouting material, but it needs to be tested to determine whether its groutability can meet the requirements.
). After the equipment foundation grouting is completed, the parts to be removed should be processed before the grouting layer is finally set.
). During the grouting construction process and before demoulding, the grouting layer should be protected from vibration and collision to avoid damage to the unhardened grouting layer.
) The horizontal distance between the formwork and the equipment base should be controlled to the left and right to facilitate grouting construction.
) If grout running occurs during grouting, it should be dealt with in time.
) When the equipment foundation grouting volume is large, mechanical stirring should be used to ensure grouting construction.
, Maintenance
) Within minutes after the grouting is completed, the curing agent should be sprayed immediately or covered with plastic film and covered with rock wool quilts for maintenance, or water should be sprayed and moisturized immediately after the grouting layer is finally set.
) During winter construction, maintenance measures should also comply with the relevant provisions of the current "Construction Acceptance Code for Reinforced Concrete Projects" (B).
) Curing time and mold removal schedule under different temperature conditions
