The concrete method for grouting by utilizing the special supporting system for the strip-shaped steel column base steel template comprises the following steps:

base layer treatment

The lower part of the steel column base is cleaned, concrete slurry at the column joint is removed, impurities such as floating ash and oil stain cannot be generated, and the steel column base is soaked in water for 8-12 hours before grouting.

Supporting formwork

Two first steel form 1 become parallel mode under, two second steel form 2 become parallel mode at last, first steel form 1, second steel form 2 intercrossing are fixed by first recess 5, second recess 4 respectively.

Stirring of grouting material

The water addition amount is preferably controlled to be 12.5 percent, the water temperature is controlled to be 20-30 ℃ and the blending water meets the drinking water standard (the net weight of each bag of non-shrinkage grouting material is 50 kg, and the water addition amount is 6.25 kg).

The mechanical stirring time of the grouting material cannot exceed 2 minutes, the primary stirring amount is used up within 30 minutes, the secondary stirring cannot be carried out, and the operation from the stirring start to the grouting end must be continuously carried out.

Grouting construction

The grout is poured from one side until the grout overflows from the other side, so that air between the steel column base and the concrete foundation can be discharged, the grouting is full, and the grouting cannot be performed simultaneously from four sides.

After grouting is started, the grouting must be continuously carried out without interruption, and the grouting time should be shortened as much as possible.

The grouting should not be vibrated during the grouting process, and if necessary, an iron wire and the like can be used for pulling and guiding the flow.

After grouting, the part to be removed is treated before final setting of a grouting layer.

During grouting construction until demolding, the grouting layer is prevented from being vibrated and collided, so that the unhardened grouting layer is prevented from being damaged.

If the slurry leakage occurs in the grouting, the treatment should be carried out in time.

When the grouting amount is large, a mechanical stirring mode is adopted to ensure grouting construction.

Maintenance measures

When grouting, the daily average temperature should not be lower than 5 ℃, after grouting, the exposed part should be sprayed with water in time, and the plastic film should be covered to keep moist. When the plastic film is adopted for covering, the exposed surface of the cement-based grouting material is tightly covered, and the condensed water in the plastic film is kept.

The grouting material should be maintained in a wet state for a maintenance time of not less than 7 d.

The above embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims.
