Slip form concrete for construction of cutting ultrahigh ditch
The invention discloses slip-form concrete for construction of a cutting ultrahigh ditch. The slip-form concrete comprises the following components in parts by mass: 261 parts of cement, 87 parts of fly ash, 877 parts of sand, 1029 parts of gravel, 146 parts of water and 5.22 parts of an additive. The slip-form concrete for construction of the cutting ultrahigh ditch has fluidity during slip-form construction of the cutting ultrahigh ditch, ensures a continuous operation process during slip-form construction, has plasticity-retaining property which is formed according to a preset section type and is not easy to deform, also has water-retaining property which does not generate segregation in the processes of mixing, transporting, vibrating and the like, and also has the advantages of high water retaining property, high water retaining property, high water retaining property and the like. The slump of smooth mold entering according to the preset time and fluidity is guaranteed, and it is guaranteed that the sliding mold advancing speed is not affected by the performance defects of concrete during sliding mold construction of the cutting ultrahigh ditch, so that the section appearance, edges and corners and the line shape of the formed cutting ultrahigh ditch are guaranteed, and the service life of the cutting ultrahigh ditch is prolonged. And the forming quality and the anti-seepage performance of the cutting ultrahigh ditch are improved while the slip form construction efficiency of the cutting ultrahigh ditch is improved.
本发明公开了一种路堑超高水沟施工用滑模混凝土，包括以下组份和质量份数：水泥261份，粉煤灰87份，砂子877份，碎石1029份，水146份，外加剂5.22份。本发明通过路堑超高水沟施工用滑模混凝土，在路堑超高水沟滑模施工时，具有流动度，确保滑模施工时的连续作业过程，并具有按预设的断面型式成型，且不易变形的保塑性，还具有在拌合、运输、振捣等过程中不产生离析的保水性，以及，具有保证按预设的时间、流动度顺利入模的坍落度，确保路堑超高水沟滑模施工时的滑模行进速率不会因混凝土自身性能存在缺陷而受到影响，以确保成型后的路堑超高水沟的断面外观、棱角和线形，提高了路堑超高水沟滑模施工效率的同时，提高了路堑超高水沟的成型质量及抗渗性能。
