    声测管施工与治理

      井孔内一律采用12V安全电压和防水带罩灯照明,井上现场可用24V低压照明。

      井下操作人员连续工作时间,不宜超过4h,应及时轮换。同时应注意的是钢模板斜顶砌之上下灰缝,应于抹灰前3天于钢模板操作架上再检查一次,遇有未勾又沉裂的应补勾填实,沉裂缝应踢出宽度不小于10mm的大缝,以保证重勾填实。如:工期要求、施工程序要求与其他分部分项工程的交叉作业状况等。 
     
      钢模板使用的砌体砖建议使用三排孔多孔或其它轻质实体砌块,当使用钢模板或多孔砖砌筑钢模板时,为提高砌体防水能力,砖之朝外面应选择棱角齐全的砖,当墙的长度与砖模数不符时,不足模数部分由实心砖或素砼调整。并明确各种机具的安全使用规程。  

          人工声测管、桩基声测管应由具有相应资质的专业队伍施工。现场用电均须安装漏电保护装置。声测管扩孔完成后,应及时组织验收并浇筑混凝土,特别是孔壁为砂土、松散填土、软土等不良土壤时不得隔夜浇筑混凝土,以免塌孔。

    Inside the hole shall use 12 v safety voltage and waterproof lamp lighting, inoue available 24 v low voltage lighting at the scene.
    The continuous operation, downhole operation personnel should not be more than 4 h, should be timely rotation. At the same time should pay attention to is the fluctuation of steel template inclined top build by laying bricks or stones mortar joint, should be 3 days prior to the rendering steel template operation frame to check again, in case of not hook and sinking crack should fill the infill, sinking crack width should be kicked out of not less than 10 mm large, in order to ensure infill. Such as: the construction period, construction program requirements and other division component project crossover operation condition, etc. Steel template using porous brick masonry is recommended to use three rows of holes or other light solid block, when using the steel template or porous brick masonry steel template, in order to improve masonry waterproof ability, and should choose out of brick complete tile edges and corners, when the length of the wall does not accord with brick modulus, modulus of fraction by solid brick or concrete adjustment. And clear procedures for safe use of various kinds of machines and tools. Artificial acoustic detecting tube, with appropriate qualifications acoustic detection tube pile foundation shall be made by the professional team construction. On-site power shall be installed leakage protection device. Acoustic detecting tube, after the completion of reaming should timely organize acceptance and pouring concrete, especially for the sandy soil, loose fill of hole wall, as well as the soft clay soil shall not be overnight when pouring concrete, so as to avoid collapse hole.
