圆形检查井
Circular inspection well
1、钢筋骨架:根据不同规格井室分别使用冷轧带肋钢筋、热轧带肋钢筋,井室、调节节全部滚焊成型。井底采用人工绑扎后与井壁绑扎或焊接在一起。
1. Reinforcement framework: cold rolled ribbed steel bar and hot-rolled ribbed steel bar are used respectively according to different specifications of well chamber, and all shaft chamber and regulating joint are rolled and welded. The bottom of the well is bound or welded with the shaft wall after manual binding.
2、混凝土搅拌:圆形井使用的混凝土是干硬性砼,严格控制原材料的质量、混凝土的用水量、保证混凝土的维勃稠度指标。搅拌设备选用的双卧轴式、程序控制、传感器称重全自动1立方搅拌站。这样充分保证了混凝土的工作度及强度。从混凝土的搅拌到浇筑基本实现自动化。
2. Concrete mixing: the concrete used in the circular well is dry and hard concrete. The quality of raw materials, the water consumption of concrete and the Weibull consistency index of concrete shall be strictly controlled. The mixing equipment adopts double horizontal shaft type, program control, sensor weighing automatic 1 cubic meter mixing station. This fully ensures the workability and strength of concrete. From the concrete mixing to pouring, the automation is basically realized.
3、圆形混凝土检查井的成型:无论是带底井室还是调节块均采用芯模振动成型。在试生产带底检查井的过程中,脱内模时井底塌落。起初受到一些似乎理论(强调脱内膜产生的负压)的影响,脱模时井底塌落,经过反复的试验,排除了原来的错误理论的干扰,我们找到了原因,改进了生产工艺,彻底解决带底井室井底不塌落现象。相继又解决养护期间井底与井壁接触处出现环形开裂等现象
3. The molding of round concrete inspection well: both the bottom chamber and the regulating block are formed by core mold vibration. In the process of trial production of inspection well with bottom, the bottom of well collapses when the internal mold is removed. At first, influenced by some seemingly theories (emphasizing the negative pressure produced by the stripping), the bottom hole collapsed when demoulding. After repeated tests, the interference of the original wrong theory was eliminated. We found out the reason, improved the production process, and completely solved the problem of no collapse at the bottom of the well chamber with bottom. The problem of annular cracking at the contact between the bottom hole and the shaft wall during the maintenance period was solved
