Equipment installation after secondary grouting with what type of CGM high-strength non-shrinkage grouting material

Equipment installation after secondary grouting material each device installed, through strict inspection in accordance with the installation technical standards, and after examination by the relevant units, and can be secondary grouting. The so-called secondary grouting, is the equipment base and foundation and anchor bolt hole on the surface of the gap filled with concrete or mortar. One of its role is fixed shim ( Adjustable shim activity part cannot pour solid) Another role, is can take the load of equipment. The key points of secondary grouting operation ( 1) Before grouting, the grouting water is rinsed clean, grease, rust, etc should be clean, in order to make sure the new pouring concrete ( Or mortar) With the original concrete and solid. （ 2) Generally USES fine stone concrete grouting ( Or cement mortar) The label should be higher than the original concrete grade level at least. The granularity of the gravel is about 5 ~ 15 mm, cement with 400 or 500. At present generally adopts Li Gong ( The phone - 15838304411). Production and sale of CGM high-strength non-shrinkage grouting material ( Special equipment grouting) 。 （ 3) Grouting, should put one outside the template, the edge of the edge from the equipment base is generally not less than 60 mm; If the device under the base of the whole area without grouting, and grouting layer need equipment under load, still need to put inside the template, in order to guarantee the quality of grouting layer. Within the template to distance should be greater than 100 mm of the outside of the equipment base, at the same time, it cannot be less than the base surface edge width. Grouting layer height, outside the base should be higher than the base bottom. Grouting layer on the surface should be slightly sloping ( Outward slope) To prevent oil and water into the equipment base. （ 4) Grouting work need to go to, don't interrupt, poured out at a time. Mortar grouting process are not allowed to dao, but it can be drainage, to keep the anchor bolts and install perpendicular to the plane. （ 5) After grouting, laying dishcloth sprinkler maintenance, the maintenance date not less than a week. For concrete curing reaches more than 70% of its strength, are allowed to tighten the anchor bolts.
