关于观察井模具的设计,在不同的观察井模具生产厂家有着不同的生产原则,但是在观察井钢模具设计上,我们需要了解他的整体构造、分段情况、布局情况以及钢板的使用厚度,连接方式等等。先是了解检查井钢模具的整体构造,它的构成模式是按照分块拼接的形式,内模需要人进去之后才能拆模,所以内模分块比外模多,如果是分块大小的话也不好拆模,所以会出现两块大的一块小的内模分块情况。
As for the design of observation well mold, different observation well mold manufacturers have different production principles, but in the design of observation well steel mold, we need to understand its overall structure, segmentation, layout, thickness and connection mode of steel plate. First, understand the overall structure of the steel mold of the inspection well. Its composition mode is in the form of block splicing. The internal mold can only be removed after people enter, so the internal mold is divided into more blocks than the external mold. If the block size * is not easy to remove the mold, so there will be two large and one small internal mold.
观察井模具的制作涉及到很多细节问题,比如预制使用的污水检查井井筒模具就需要额外定制预留孔,而现浇生产的污水井直接在模板上割出孔来就可以了。观察井模具预留孔的设置还要看使用的管道材质以及壁厚大小,尤其要注意500毫米以上的下水管道使用的水泥管,壁厚一般都是随着管道的内径增加而增加的。水泥检查井井筒模具预留孔的使用有效的满足了二通、三通、四通管道的铺设问题,尤其实在预制污水井的时候,不管就是几通的管道井,都是可以通过放置相同数量的预留孔来实现连接管道的设置了。
The fabrication of the observation well mold involves many details. For example, the prefabricated sewage inspection well shaft mold needs additional customized reserved holes, while the cast-in-situ sewage well can directly cut holes on the template. The setting of the reserved hole of the observation well mold also depends on the pipe material and wall thickness. In particular, pay attention to the cement pipe used for the sewer pipe above 500mm. The wall thickness generally increases with the increase of the inner diameter of the pipe. The use of reserved holes in the shaft mold of the cement inspection well effectively meets the laying problems of two-way, three-way and four-way pipes. Especially when prefabricating the sewage well, no matter how many pipe wells are connected, the setting of connecting pipes can be realized by placing the same number of reserved holes.
其次是分段,一般观察井都是按照1米一节的制造模式,这样不论是安装还是混凝土检查井的生产都会便利,上下可以使用螺丝进行连接,这样可以生产的检查井高度就可以随意调节了。在布局情况上,检查井通常是按照数字的形式进行标注,往往现场浇筑的布局比预制检查井复杂一些,要求底部割出大小与所铺设的管道相匹配的预留孔。预制检查井井筒钢模具的板材厚度没有特别要求,通常情况下都是使用4毫米的钢板,这样就可以保证多次重复使用的次数
The second is segmentation. Generally, the observation well is manufactured according to the one meter section, so that it will be convenient for both installation and concrete inspection well production. Screws can be used to connect up and down, so that the height of the inspection well that can be produced can be adjusted at will. In terms of layout, inspection wells are usually marked in the form of numbers. The layout of on-site pouring is often more complex than that of prefabricated inspection wells. It is required to cut reserved holes matching the size of the laid pipeline at the bottom. There are no special requirements for the plate thickness of the prefabricated inspection shaft steel mold. Usually, 4mm steel plate is used, so as to ensure the number of times of repeated use
