声测管、成桩基声测管必须严格按图施工，若发现标题题目需要变更，应及时与设计负责人联系，孔桩基声测管护壁后在无可靠的安全技术措施条件下，严禁破石修孔。做好分格线，特别在装饰面层为无分格线的面砖、马赛克等钢模板上打底也应在适当位置留置分格线，用油膏填缝后，方可上面层。特别是在窗边、顶层墙体窗下和不同结构材料接触界面处，如墙体与梁底、墙体与柱边等薄弱部位都是我们应重点防范的关键。

　　目前建议优先考虑使用益胶泥新型高分子粘接材料代替传统水泥作为板材、块材的粘贴材料，益胶泥具有用量少、本身厚度薄、施工工艺简单等优点，避免了使用水泥等传统粘贴材料因浸砖、洒水不够而引起的空鼓、脱落等隐患。
　　
　　按合同要求施工中需要采取的措施。在医院或其他有毒物质存放区施工，应先检查有毒物质对人体的伤害程度，再确定是否采用人工声测管的施工方法。
　　
　　现场设专人做好声测管桩基声测管施工记录，并负责对安全施工实施跟踪监督，做好监督记录。
　
　　熟悉桩基声测管基础工程设计图纸、说明及施工要求，以及完整的地质勘察呈文书，以掌握施工区域各层土质的物理力学性质，桩基声测管持力层的岩土特征及埋深、地下水位及分布情况。
　　

　　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。

Acoustic detecting tube, as acoustic detection tube pile foundation must be strictly according to the graph construction, if discover the title title needs to change, should be timely contact with design leader, acoustic detection after the tube wall hole pile foundation under the condition of no safety technical measures on, it is strictly prohibited to break the Shi Xiu holes. Points, lines, especially for no portion in architectural surface grid lines on the tiles, Mosaic and so on steel template rendering should also be retained in the appropriate space grid lines, anoint caulking, before the layer above. Especially in the window below the window, the top wall and different structural material contact interface, such as wall and beam bottom, side wall and column weak positions are we should focus on the key to prevent.
Currently recommended priority use good cement as a new polymer adhesive material instead of traditional cement plate, block material paste material, cement has the advantages of low dosage, itself thickness thin, simple construction technology etc, to avoid the use of cement and other traditional paste material caused by sprinkling water immersion brick, not enough of the empty drum, loss etc.
Need to be taken in accordance with the contract requirements and construction measures. In a hospital or other toxic materials storage area construction, should first check the toxic substances, the harm of human body to determine whether the construction method of using artificial acoustic detecting tube.
The designated persons do sound recording acoustic detection tube tube pile foundation construction, and is responsible for tracking and monitoring for security construction, supervision and recorded.
Familiar with acoustic detection tube pile foundation engineering design drawings, specifications and construction requirements, as well as the complete geological survey and submit documents, in order to grasp the construction area of the physical and mechanical properties of the layers of soil, pile foundation subsoil geotechnical characteristics of the acoustic detection tube and buried depth, the underground water level and distribution.
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 procedure, 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 the 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 the 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. The electricity shall be installed leakage protection device. After the completion of the test tube, reaming, shall promptly 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.
