CGM high-strength non-shrinkage grouting material construction work instructions

CGM high-strength non-shrinkage grouting material construction guidance, nouns, the term 1, CGM materials, with high strength material as aggregate, cement as cementing the seam an agent, complementary with high flow, micro expansion, made from materials such as anti segregation. At the construction site to join a certain amount of water, stir well after use. 2, weight method, based on CGM material construction, the use of the material liquid characteristic, within the scope of the grouting flow freely, satisfies the requirement of grouting method. 3, high funnel method, is in CGM material construction, only on its liquidity can't meet the requirements, the use of the grouting of potential difference, meet the requirements of the grouting method. 4, pressure grouting method, which is in CGM material construction, the grouting pressure equipment, to meet the requirements of the grouting method. 2, scope of application of CGM grout material 1, CGM grout material scope of CGM grout material scope of the lowest temperature ( ℃) CGM— 1 ( Ordinary) Anchor bolt anchoring, buried steel bar, thickness of grouting layer 30 mm < delta < 150 mm equipment foundation secondary grouting. With the requirement of oil equipment foundation secondary grouting. CGM— 4 ( Rugged) Grouting layer thickness of 150 mm or more secondary grouting equipment foundation. The structure of the beam, slab, column, foundation and ground reinforcement reinforcement ( Repair the thickness of 40 mm or higher) 。 With the requirement of oil equipment foundation secondary grouting. 5CGM— 2 ( Ordinary) Grouting layer thickness of 30 mm < delta < 150 mm equipment foundation secondary grouting. CGM— 3 ( Rugged) Grouting layer thickness of 150 mm or more secondary grouting equipment foundation. The structure of the beam, slab, column, foundation and ground reinforcement reinforcement ( Repair the thickness of 40 mm or higher) 。 2, CGM grout material construction should be in the specified temperature range. Otherwise, the corresponding measures should be taken.
