| U型槽模具有什么优点？ What are the advantages of U-groove dies? 首先U型槽现场预制应有砼标号及拌和配合比并按标准取样试压， Firstly, the concrete label and mixing proportion should be used in the field prefabrication of U-shaped groove and the standard sampling and pressure test should be carried out. 在预制过程中应符合规范有关规定；内外侧表面应平直圆滑，不得出现蜂窝、 In the prefabrication process, the relevant provisions of the specification shall be complied with; the inner and outer surfaces shall be smooth and smooth, and no honeycombs shall appear. 麻面现象；端面应平整并与其轴线垂直；强度和尺寸应满足设计要求。 Hemp surface phenomenon; end surface should be flat and perpendicular to its axis; strength and size should meet the design requirements. U型槽灌溉渠工程施工流程： Construction process of U-shaped channel irrigation canal project: 施工准备→土方开挖→验槽→断面欠方回填土→渠道U形槽底砂垫层铺设→订购砼U型槽、进场检验→砂垫层铺筑高程复核→安放U型槽调整纵坡、高程→U型槽接缝处理→压顶砼浇筑→渠道U型槽外观检测、放水检验→交工验收。 Construction preparation earthwork excavation groove inspection underfill of section sand cushion laying at the bottom of channel U-shaped groove ordering concrete U-shaped groove, entrance inspection sand cushion laying elevation re-check placing U-shaped groove to adjust longitudinal slope, elevation joint treatment of U-shaped groove top-pressing concrete pouring channel U-shaped groove appearance inspection, drainage inspection handover acceptance and acceptance. |
