强夯施工过程质量控制措施有哪些?在强夯施工过程中,要注意做好检查工作,比如测量放线、夯锤落距、夯点间距、夯击遍数等,要遵循三检制,并做好检查记录,从而保证强夯施工质量,保证整个工程质量。
What are the quality control measures during dynamic compaction construction? In the process of dynamic compaction construction, pay attention to the inspection work, such as measuring and setting out, rammer drop distance, tamping point spacing, tamping times, etc., follow the three inspection system, and make inspection records, so as to ensure the construction quality of dynamic compaction and the quality of the whole project.
强夯工程开工前,检查测量放线、夯锤重量、夯锤落距是否准确,做好验收工作,确保夯击过程中落距始终保持不变,并选择设计要求的机械设备组织施工,确保每击都能达到设计单击夯击能。
Before the commencement of dynamic compaction project, check whether the measurement and setting out, the weight of the rammer and the falling distance of the rammer are accurate, do a good job in acceptance, ensure that the falling distance remains unchanged during the ramming process, and select the mechanical equipment required by the design to organize the construction, so as to ensure that each blow can meet the design ramming energy.
要复核测量基准线、水准点和定位桩,将施工测量控制点引到不受施工影响的稳固地点。
The survey datum line, benchmark and positioning pile shall be rechecked, and the construction survey control points shall be led to a stable place not affected by the construction.
每一锤在正式提升前,夯锤要准确对好锤位,保证每一锤都要提升到满足设计夯能要求的高度。
Before the formal lifting of each hammer, the hammer position shall be accurately aligned to ensure that each hammer shall be lifted to a height that meets the design tamping energy requirements.
夯锤落下后,夯坑底部有倾斜超过20度的,用土将坑底补平,再进行下次的夯击作业。
After the rammer falls, if the bottom of the tamping pit is inclined more than 20 degrees, the pit bottom shall be leveled with soil before the next tamping operation.
每个夯坑的每一击,都要记录了夯坑的下沉量,并保证施工记录的准确性。
The settlement of each tamping pit shall be recorded for each blow of each tamping pit, and the accuracy of construction records shall be ensured.
强夯施工现场及夯坑由于降雨或地下水位上升等原因积水时,要及时采取排水措施,等谁排干后,再将夯坑进行回填。
In case of ponding on the construction site of dynamic compaction and the tamping pit due to rainfall or rise of groundwater level, drainage measures shall be taken in time, and the tamping pit shall be backfilled after being drained.
在强夯施工过程中要实施“三检制”及工程监理程序报验工作,在每道工序完成后,对本工序实行隐蔽工程报验程序,经过监理验收合格后才能进行下道工序施工。
In the process of dynamic compaction construction, the "three inspection system" and the application for inspection of engineering supervision procedures shall be implemented. After each process is completed, the application for inspection of concealed works shall be implemented for this process. The construction of the next process can only be carried out after passing the acceptance of the supervisor.
强夯施工
Dynamic compaction construction
强夯各遍施工前,要由专职人员测量场地 标高,为强夯地面平均下沉量和地面下沉量提供依据。
Before each construction of dynamic compaction, the site elevation shall be measured by full-time personnel to provide basis for the average ground subsidence and ground subsidence of dynamic compaction.
测量放线时,测量员要在施工区域周围按施工布点图隔排放置固定的标志桩,保证各次放线的夯击同一点时的误差不超过运行值,以防止漏夯。每次放线都要做详细的测量记录,并对各排标志桩进行校核,测量结果记录要现场监理工程师签字就可以了。
During surveying and setting out, the surveyor shall place fixed marker piles around the construction area in rows according to the construction layout, so as to ensure that the error when tamping the same point of each setting out does not exceed the operating value, so as to prevent missing tamping. Detailed measurement records shall be made for each setting out, and each row of marker piles shall be checked. The measurement result records shall be signed by the on-site supervision engineer.
测量员控制每个夯点的夯击数和每击夯沉量以及夯坑深,并认真填写强夯施工记录;质检人员在现场要进行不定期检查,严格控制质量,按照施工方案及规范随意抽检施工质量检查项目,比如夯锤落距、夯点间距、夯击遍数、夯锤重量等。
The surveyor shall control the number of tamping blows, each tamping settlement and tamping pit depth of each tamping point, and carefully fill in the dynamic compaction construction record; The quality inspection personnel shall conduct irregular inspection on the site, strictly control the quality, and randomly inspect the construction quality inspection items according to the construction scheme and specifications, such as the falling distance of the rammer, the spacing of tamping points, the number of tamping times, the weight of the rammer, etc.
