- grouting material construction requirements Construction of grouting material

grouting construction requirements grouting material how construction grouting material how to correct the construction shall meet the following requirements: when the & # 8195;   1) Grouting material from a side down, until the other side of the overflow, facilitate discharge equipment base and the air between the concrete foundation, makes a full grouting, grouting will be made from the four side and at the same time.     2) When set the foundation grouting rate is bigger, mechanical agitation modes should be adopted to ensure the grouting construction.     3) At the start of the grouting material, must be continuous, not continuous, and should shorten the grouting time as much as possible.     4) Grouting material pulp, if appear should handle in time.     5) In the process of grouting material is unfavorable and vibrating, article ferula and pull the diversion if necessary.     6) Template and equipment of the base of horizontal distance should be controlled in 100 mm or so, to facilitate grouting construction.     7) Grouting material thickness should not be longer than 100 mm.     8) In henan until before the release, in the process of grouting material construction should flee c50 grouting material layer grouting by vibration and impact, so as not to damage the outstanding hard layer grouting.     9) After the equipment foundation grouting material, to eliminate the part should be in the grouting layer before the final set for processing.     10) How much one ton of grouting material can fill cubic is longer than the equipment or track foundation grouting, section construction should be adopted. Each section length with 7 m advisable.     11) For grouting material layer thickness is greater than 1000 mm large volume of equipment foundation grouting, can according to the total amount when mixing grouting material ratio 1:1 add 0. 5 mm stones, but need to the test can determine whether its can be achieved.     12) Grouting material such as found in the process of surface exudation, there can be asa small amounts of CGM dry, blot moisture.
