预制钢筋混凝土检查井装配工法

Precast reinforced concrete inspection well assembly method

一、产品功能用途：

1. Functional use of products:

1.钢筋混凝土检查井相关性能需符合标准：JC/T2241-2014；

1. the performance of reinforced concrete inspection well should meet the standard: JC/T2241-2014;

2.检查井是地下管道中重要的构筑物，对城市功能的发挥、环境保护及人民生活都有着重要影响。目前我国地下管道检查井的用材及施工工艺比较落后，主要采用粘土砖砌筑，已落后于我国城市的快速发展。预制混凝土检查井的生产有力的推动了目前周边地区的地下管道检查井的升级，可更好的服务城市的发展进程。

2. Inspection wells are important structures in underground pipelines, which have an important impact on urban function, environmental protection and people's lives. At present, the material and construction technology of underground pipeline inspection wells in China are relatively backward, mainly using clay brick masonry, which has lagged behind the rapid development of cities in China. The production of prefabricated concrete inspection wells has effectively promoted the upgrading of underground pipeline inspection wells in the surrounding areas, and can better serve the development process of the city.

二、产品运输及装卸车注意事项：

Two. Matters needing attention in product transport and loading and unloading vehicles:

  1.预制钢筋混凝土检查井为重型货物，需有专业的装车团队及运输团队进行装车及运输服务，方不会对检查井质量造成任何影响。

1. Prefabricated reinforced concrete inspection wells are heavy cargo. Professional loading team and transportation team are required to carry out loading and transportation services. This will not affect the quality of inspection wells.

2.钢筋混凝土检查井为重型货物，卸车时应采用专业卸车机械、工具，用吊装孔进行卸车和吊装，避免造成不必要的损失。

2. Reinforced concrete inspection wells are heavy cargo. When unloading trucks, special unloading machines and tools should be used, and lifting holes should be used for unloading and hoisting, so as to avoid unnecessary losses.

三、卸车注意事项：

Three, unloading matters needing attention:

1.卸车时将产品轻起轻放，产品较重，容易造成磕碰。

1. when unloading, the product will be lighter and lighter, and the product will be heavier.

2.不要采用钢丝绳贯穿预留孔的方式进行卸车，自重较大，承受力比较集中，容易造成井室裂纹。

2. Do not unload the truck by the way of wire rope penetrating through the reserved holes. It is easy to cause shaft cracks because of its large dead weight and concentrated bearing capacity.

3.卸车时不要采用将预制井室直接滚下车辆的方式进行卸车,此方式会严重影响产品的质量，易造成严重的安全事故。

3. Do not unload the truck by rolling the prefabricated well chamber directly off the truck. This method will seriously affect the quality of the product and cause serious safety accidents.
