VACUUM DEWATERING TREATMENT METHOD IN CONCRETE SURFACE LAYER
PROBLEM TO BE SOLVED: To provide a vacuum dewatering treatment method in a concrete surface layer capable of surely bringing an over mat into close contact, and capable of providing a high degree of vacuum, even in concrete many in fine irregularity on a surface since the water content is little.SOLUTION: Concrete 3 is placed, a moisture included inside the concrete 3 is floated on a surface by pressing the surface, an airtight over mat 1, which is formed larger by a predetermined width than an outer peripheral edge shape of a filtration mat 2, is coated on floating water 31 on the surface of the filtration mat 2 and the concrete 3, and after bringing a seal part 11 on the outer peripheral edge of this over mat 1 and the surface of the concrete 3 into close contact with each other, an undersurface of the over mat 1 is decompressed by a vacuum pump P, and a surface layer of the concrete 3 is compacted and dewatered in a vacuum via the filtration mat 2.SELECTED DRAWING: Figure 5
【課題】含水量が少なくて表面に微細な凹凸の多いコンクリートであっても、オーバーマットを確実に密着させることができて高い真空度を得ることができるコンクリート表層における真空脱水処理方法を提供する。【解決手段】コンクリート３を打設し、表面を押圧することによって、コンクリート３の内部に含有した水分を表面に浮上せしめ、ろ過マット２の外周縁形状よりも所定幅だけ大きく形成した気密性のオーバーマット１を、ろ過マット２およびコンクリート３の表面における浮上水３１の上に被覆して、このオーバーマット１の外周縁におけるシール部１１とコンクリート３の表面とを密着せしめた後、真空ポンプＰによってオーバーマット１の下面を減圧して、ろ過マット２を介してコンクリート３の表層を圧密して真空脱水する。【選択図】図５
