检查井钢模具在制作之前首先需要考虑到两个重点,一是检查井钢模具的周转次数,
每套检查井钢模具都不止是使用几次这么简单,而是要考虑到长久使用,所以,在选
择检查井钢模具原材料的时候要具备一定的刚度、强度,要**检查井模具不会变形
。二是检查井钢模具脱模问题,这也是制作检查井钢模具时特别注重的一点,检查井
钢模具技术人员在设计图纸时,一定要保证检查井钢模具好安装、好拆模。
无论是污水检查井模具、雨水检查井模具还是电缆检查井模具,模具上边都有预留孔
模具,预留孔模具的形状基本都是圆形的,预留孔模具的尺寸有直径30cm、40cm、
50cm、60cm、70cm、80cm、90cm、100cm等,通常检查井模具直径越大预留孔模具的
尺寸就越大。预留孔模具的安装方式是在检查井模具的内外模中间位置,使用螺丝将
预留孔模具固定在模具,前提是在浇筑钢筋混凝土之间先将预留孔模具安装好,等到
混凝土浇筑成型之后拆模时再取出预留孔模具。
Two key points should be considered before making the inspection well
steel mould. One is the turnover times of the inspection well steel mould.
Each set of inspection well steel mould is not only used several times,
but also considered for long-term use. Therefore, when selecting the raw
materials of the inspection well steel mould, it is necessary to have
certain stiffness and strength to ensure that the inspection well mould
will not deform. The second is the demoulding of the steel mould of the
inspection well, which is also a point of special attention when making
the steel mould of the inspection well. When designing the drawings, the
technicians of the steel mould of the inspection well must ensure that the
steel mould of the inspection well is well installed and removed.
Whether
it is the sewage manhole mold, rainwater manhole mold or cable manhole
mold, there are reserved hole molds on the mold. The shape of the reserved
hole molds is basically circular. The dimensions of the reserved hole
molds are 30cm, 40cm, 50cm, 60cm, 70cm, 80cm, 90cm and 100cm. Generally,
the larger the diameter of the manhole mold, the larger the size of the
reserved hole mold. The installation method of the reserved hole mold is
to fix the reserved hole mold in the mold with screws in the middle of the
inner and outer mold of the inspection well mold. The premise is to
install the reserved hole mold between the pouring of reinforced concrete,
and take out the reserved hole mold when the mold is removed after the
concrete pouring is formed.
