Embodiment 1

[0034] Adopt the early-strength grouting material that overweight, oversized equipment installation of the present invention is used, its proportioning is counted as in parts by mass:

[0035] Cement: 1.00

[0036] Fly ash: 0.21

[0037] Expansion agent: 0.1

[0038] Coagulant regulator: 0.15

[0039] Retarder: 0.004

[0040] Water reducer: 0.004

[0041] Yellow sand: 1.19

[0042] Defoamer: 0.004

[0043] Pebbles: 1.1.

[0044] Among them: the cement is P042.5R, the fly ash is low-calcium grade II ash, the expansion agent is calcium sulfoaluminate, the coagulation regulator is gypsum, the retarder is sodium gluconate, and the water reducer is acrylic acid graft copolymerization The yellow sand has a particle size of 0.315-5mm, the medium-coarse sand with a fineness modulus Mx of 2.3-3.7, the pebbles have a particle size of 5-10mm, and the defoaming agent is silicon dioxide.

Abstract

An early-strength grouting material for overweight and oversized equipment installation is characterized in that the raw materials are composed of cement, fly ash, expansion agent, coagulation regulator, retarder, water reducer, yellow sand, defoamer and pebbles, and its The ratio is calculated in parts by mass: cement: 1.00~1.05, fly ash: 0.18~0.22, expansion agent: 0.1~0.12, coagulation regulator: 0.13~0.16, retarder: 0.003~0.005, water reducer: 0.003~0.005, yellow sand: 1.09~1.29, defoamer: 0.004~0.006, pebble: 1.1~1.3. The early-strength grouting material for installation of super-heavy and super-large equipment and the construction method thereof have the advantages of super-early strength, fast setting speed, high mechanical performance, shortened construction period, and reduced engineering cost.

Description

technical field [0001] The invention relates to an early-strength grouting material for foundation engineering, in particular to an early-strength grouting material for overweight and oversized equipment installation and a construction method thereof. Background technique [0002] Grouting material is a kind of powder formulated with cement, expansion agent, water reducer, defoamer and other additives. When in use, it can be used after adding water and stirring evenly, which is very convenient. The grouting material has the characteristics of leveling, early strength, high strength, micro-expansion, and no pollution to the surrounding environment, so it is widely used in metallurgical industry, electric power industry, transportation industry and other fields. [0003] In the oil and gas (large diameter) longitudinal welded pipe project constructed by Baosteel, the main line of the longitudinal welded pipe production line project is the introduction of complete sets of tech...
