模具性能：

只是用于現(xiàn)場(chǎng)澆筑的圓形水泥檢查井模具往往更加需要定制打造。這種模具通常由內(nèi)模、外模和堵頭三個(gè)部分共同構(gòu)成，為了預(yù)制件在安裝后能起到隔水的作用，并在地下長(zhǎng)期使用而不坍塌，使用圓形水泥檢查井模具生產(chǎn)出的水泥檢查井預(yù)制件壁厚一般在10cm到20cm之間，以其抗壓能力，因此用于生產(chǎn)此類預(yù)制件的模具內(nèi)模和外模直徑也需要有較為固定和均勻的差距，一般相差20cm到40cm，因此需要留有預(yù)留孔的地方就需要使用到堵頭余檢查井預(yù)制件厚度相同的堵頭，以產(chǎn)出產(chǎn)品的厚度均勻。The molds of circular cement inspection well are composed of internal formwork and external formwork. There are some differences in splicing methods according to different shapes, but there is no great difference in use methods. They can be used for both prefabrication production and on-site pouring.

Mold performance: the circular cement inspection well mold used for on-site pouring often needs to be customized. This kind of mold is usually composed of three parts: inner mold, outer mold and plug. In order to prevent the prefabricated parts from water after installation and use underground for a long time without collapse, the wall thickness of the prefabricated parts of the cement inspection well produced by the circular cement inspection well mold is generally between 10cm and 20cm, which is based on its compressive capacity, Therefore, the diameters of the inner mold and the outer mold of the mold used to produce such prefabricated parts also need to have a relatively fixed and uniform gap, with a general difference of 20cm to 40cm. Therefore, where reserved holes need to be reserved, plugs with the same thickness of the prefabricated parts of the remaining inspection wells need to be used to produce products with uniform thickness.
