Grouting method for large-scale equipment base in high-temperature drying environment

Abstract

The invention discloses a grouting method for a large-scale equipment base in a high-temperature drying environment. The grouting method includes preparation before grouting, flowing grouting and grouting material maintenance. The grouting method for the large-scale equipment base in the high-temperature drying environment has the technical effect that through the cyclic operation method includinggrouting, vibrator vibrating and re-grouting, bubbles in the equipment base can be effectively removed; and meanwhile, a method of injecting a grouting material into the equipment base from a grouting opening in the center of the upper surface of the equipment base is adopted, the problem of poor fluidity of the grouting material under the high-temperature drying condition can be solved, groutingis compact, and the construction quality is better.

Description

technical field [0001] The invention relates to the installation of mechanical equipment bases, in particular to a grouting method for large equipment bases used in high-temperature and dry environments. Background technique [0002] During the installation of mechanical equipment, in order to ensure the stability of the equipment, it is necessary to grout the base of the equipment so that the base of the equipment is fixedly connected to the foundation. The base of some large-scale equipment such as the large-scale grinding machine used in cement plants is different from the steel structure base of general equipment. Air bubbles often exist inside the equipment base when the internal ribs of the base are staggered and grouted. In some high-temperature and dry areas, the temperature often reaches Above 30°C to 40°C, the air humidity is very low. Under this condition, the initial setting time of the grouting material is shortened, and the fluidity is significantly reduced. If...

The base of some large-scale equipment such as the large-scale grinding machine used in cement plants is different from the steel structure base of general equipment. Air bubbles often exist inside the equipment base when the internal ribs of the base are staggered and grouted. In some high-temperature and dry areas, the temperature often reaches 30°C to above 40°C, the air humidity is very low. Under this condition, the initial setting time of the grouting material is shortened, and the fluidity is significantly reduced. If the ordinary grouting method is used, it is difficult to ensure the grouting density and the project quality.
