塑料检查井的管道口径和井筒口径介绍!

  与国外相比,在中国更常见的是20层以上的高层建筑,社区的建筑面积从数十万平方米到数百万平方米不等。一般来说,国内社区占地面积越大,人口越多,人口密度也就越高。因此,在设计管道时,小区雨水污水管道的直径通常比国外大得多。这也直接增加了塑井注塑模具的体积,提高了模具的加工难度。在北方,污水管道一般小于200毫米,但在南方,它小于250毫米,在一些地区,直径大于315毫米。在一些大型居民区,流失的直径是¢800毫米。因此,虽然塑料检验井是在建筑小区中使用的,但从规范的角度来看,已被列入市政应用的范围。
  Compared with foreign countries, more common in China is high-rise buildings with more than 20 floors. The building area of the community varies from hundreds of thousands of square meters to millions of square meters. Generally speaking, the larger the area and population of the domestic community, the higher the population density. Therefore, in the design of pipeline, the diameter of rainwater and sewage pipeline in residential area is usually much larger than that in foreign countries. This also directly increases the volume of the injection mold of the plastic well and improves the processing difficulty of the mold. In the north, sewage pipes are generally less than 200 mm, but in the south, they are less than 250 mm, and in some areas, they are more than 315 mm in diameter. In some large residential areas, the maximum diameter of the loss is ¢ 800mm. Therefore, although the plastic inspection well is used in the building area, it has been included in the scope of municipal application from the perspective of norms.
  Ganizational 315mm、Ganizational 450mm和Ganizational 630mm是施工区域常见的塑料止回井。不适合清洗,由的机械工具清洗。
  Ganizational 315mm, 450mm and 630mm are common plastic check wells in the construction area. It is not suitable for cleaning. It is cleaned by professional mechanical tools.
  在产品结构设,必须考虑机械操作要求。例如,当弹簧钢棒通过井筒时,与井座的连接部分位于井筒的连接处。为了防止工具卡死,影响疏浚效果,在现场设置曲率半径不小于10mm的圆弧。
  Mechanical operation requirements must be considered in product structure design. For example, when the spring steel rod passes through the shaft, the connection part with the well seat is located at the connection part of the shaft. In order to prevent the tool from jamming and affect the dredging effect, an arc with a radius of curvature not less than 10 mm shall be set on site.

  在实际推广中,用户虽然能很好地理解机械清洗的原理,但仍不能完全接受机械清洗的概念。每根管线长度间隔20~30m,在转角或汇合处,通常设置专人清理检查。塑料检查井还处于早期阶段,这并没有什么问题。首先,除了一些大中城市,机械清洗工具并没有广泛使用,所以用户对这些工具并不熟悉。其次,介质在国内的住宅网络中排放比较复杂,在存在工具无法清除的情况下,人们清除仍然是一种保险的选择。例如,一般社区的厨房水槽通常没有破碎装置,废水不经破碎直接排入管网,这也是管网正常运行的隐患。总的来说,可以预见,随着塑料探井应用范围的扩大和机械清洗工具的普及,用户对塑料探井的要求主要是小型化。
  In practice, although users can understand the principle of mechanical cleaning well, they still can not fully accept the concept of mechanical cleaning. The length interval of each pipeline is 20-30m. At the corner or junction, a special person is usually arranged to clean and inspect. The plastic inspection well is still in its early stages, which is not a problem. First of all, except for some large and medium-sized cities, mechanical cleaning tools are not widely used, so users are not familiar with these tools. Secondly, the discharge of media in the domestic residential network is more complex. In the case that there are tools that can not be removed, people still have the choice of insurance. For example, the kitchen sink in the general community usually has no crushing device, and the waste water is directly discharged into the pipe network without crushing, which is also the hidden danger of the normal operation of the pipe network. In general, it can be foreseen that with the expansion of the application scope of plastic exploratory wells and the popularization of mechanical cleaning tools, users' requirements for plastic exploratory wells are mainly miniaturization.
  塑性探伤井埋于地下时,作用于井盖垂直方向的动荷载、自身井体重量和作用于井筒的土阻力共同构成探伤井的垂直荷载。所有的垂直载荷更终转移到井座,这是塑料探井的核心部分。
  When the plastic flaw detection well is buried in the ground, the dynamic load acting on the vertical direction of the well cover, the weight of its own well body and the soil resistance acting on the shaft together constitute the vertical load of the flaw detection well. All vertical loads are eventually transferred to the well seat, which is the core part of the plastic exploratory well.
