Concrete slurry defoaming construction process based on road construction

Abstract

The invention discloses a concrete slurry defoaming construction process based on road construction, and belongs to the field of road construction. Through the arrangement of an inner movable base plate, after slurry is poured, an inner movable converter sheet in the inner movable base plate continuously moves upwards and backwards when a vibrating rod passes through the position in the moving process through the cooperation of the effect of the vibrating rod; therefore, concrete slurry at the bottom is stirred by the internal moving converter sheet, concrete at the end portion is continuously recombined and collapsed, small gaps which are difficult to eliminate by a vibrating rod are effectively eliminated, compared with the prior art, the amount of gaps in a solidified concrete road is greatly reduced, the strength of the concrete road is effectively improved, and the cracking time is effectively prolonged. And in the ascending and falling process of the inner movable converter sheet, water in the inner movable converter sheet is continuously subjected to position transfer, so that after the inner movable converter sheet falls back, the slurry above the inner movable converter sheet can be briefly impacted, the collapse of gaps is further improved, and the effect is better.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a concrete slurry defoaming construction technology based on road construction. Background technique [0002] For the old roadbed, the thickness of the cement concrete pavement is generally 18-22cm; [0003] For the new subgrade, the thickness of the cement concrete pavement is 22-25cm. Generally not less than 20cm, it tends to be thicker at present, and there are many projects above 25cm on the main road. If the subgrade is not good, there are many fully reinforced pavements. After the promulgation of the new specification for concrete pavement, the value of the formula was changed, and the reinforcement ratio of reinforced concrete was greatly increased. [0004] When the concrete pavement is being constructed, after the slurry is laid, it is generally compacted by vibrating rods to remove the air inside the slurry and the gaps formed by mutual pushing. In actual operation, ...

Problems solved by technology

[0004] When the concrete pavement is being constructed, after the slurry is laid, it is generally compacted by vibrating rods to remove the air inside the slurry and the gaps formed by mutual pushing. In actual operation, the vibrating rods generally remove Large internal voids often have relatively small voids that are difficult to remove, resulting in easy cracking inside the concrete pavement formed after curing. relatively low service life
