观察井模具从形状上一般分为两种，一种是圆形检查井，一种是方形检查井，有内模和外模组成，内模与外模之间的距离就是将来生产的检查井壁厚，一般壁厚为15cm，一般检查井的钢板厚度在4-5毫米之间，检查井应用非常广泛，市政，小区，通信，电缆，电力，排水，污水，雨水等等。Observation well molds are generally divided intoo types from the shape. One is a circular inspection well, and the other is a square inspection well. It consists of an inner mold and an outer mold. The distance been the inner mold and the outer mold is the thickness of the inspection well wall produced in the future. General wall thickness is 15cm, The thickness of steel plates in general inspection wells is been 4-5 mm, and the inspection wells are widelyed, municipal,munity,munication, cable, electricity, drainage, sewage, rainwater, and so on.

观察井模具施工现场预制型水泥模具具实用性的变现就是拆装方便，生产快捷，切没有对相应的水泥井体构件造成一定程度的损伤，这就是施工的主要要求范围之中的几项重点，模具可以进行现场浇筑和预制使用，其中浇筑使用的模具可以适应多种的混凝土，因为这种钢制模首先要进行现场安装好之后才可以进行混凝土的预装，这样就极大可能的出现模具膨胀的可能，所以定位才是根本所在，观察井模具主要有内外模板相继组成，每一个型腔都具有相应的定位销，这样就可以达到降低振捣或是混凝土预装过程中的模板移位的现象发生，始终保持合格的尺寸塑造成型。

To observe the practical realization of prefabricated cement molds in the construction site of well mold is that it is convenient to disassemble and install, and the production is fast. The cutting does not ce a certain degree of damage to the corresponding cement shaftponents. This is one of the key points in the main requirements of construction. Mould can beed for on-site pouring and prefabricatede, in which the moldsed for pouring can be adapted to a variety of concrete, bece this steel mold t be installed in the field before the concrete can be pre-installed, which is highly likely. The possibility of mold expansion, Therefore, positioning is the fundamental point. Observing that the well mold is mainlyposed of internal and external templates, each cavity has a corresponding positioning pin, so that the phenomenon of reducing the displacement of the template during vibration or pre-loading of concrete can be achieved. Always keep fit for size molding
