一、产品功能用途：
1. Functional uses 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 play an important role in the development of urban functions, environmental protection and people's lives. At present, the material and construction technology of underground pipeline inspection wells in our country are relatively backward, mainly using clay brick masonry, which has lagged behind the rapid development of www.jiazanmiaomu.com www.dzyangguang.com.cn www.yjlvhua.com www.xindejinwei.com www.bdylyx.com www.bdxm.com.cnChina's cities. The production of precast concrete inspection wells has effectively promoted the upgrading of underground pipeline inspection wells in the surrounding areas, which can better serve the urban development process.
二、产品运输及装卸车注意事项：
Two, product transportation and loading and unloading car attention:
  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。
The 1. prefabricated reinforced concrete inspection well is a heavy cargo, which requires a professional loading team and transport team to carry on the loading and transportation service. No effect on the quality of the inspection well will be caused.
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. the reinforced concrete inspection well is a heavy cargo. When unloading the car, the professional unloading machinery and tools should be used, the unloading and hoisting should be carried out with the hoisting hole to avoid unnecessary losses.
三、卸车注意事项：
Three, unloading the car 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 use the way of wire rope through the reserved hole to unload the truck. The self weight is bigger and the bearing capacity is relatively concentrated, so it is easy to cause cracks in the well chamber.
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。
When 3. unload the car, do not use the prefabricated well room to roll down the vehicle directly. This way will seriously affect the quality of the product and cause serious safety accidents.
四、管道与检查井衔接流程：
Four, pipeline and inspection well link flow:
1、检查井与管道连接一般采用管顶平接，采用1:2防水水泥砂浆或聚氨酯掺和水泥砂浆嵌缝封堵。
1, the connection between inspection wells and pipelines is usually connected by pipe roof, and 1:2 waterproof cement mortar or polyurethane cement mortar is used to seal the joints.
2、具体做法为：在管道伸进井室前，在管道下部120度范围内座防水砂浆，挤压管道使防水砂浆与管道连接密实，以砂浆外溢为宜。将管道两侧和上部分别以防水砂浆填满，插捣防水砂浆，直至完全饱满，最后抹出三角状防水砂浆，宽度保持在5-6cm。
2, the concrete method is: before the pipe is extended into the well chamber, the waterproof mortar is located in the 120 degree range of the lower part of the pipe, and the extrusion pipe makes the waterproof mortar and the pipe connection dense, and the mortar spillover is appropriate. The two sides and the upper part of the pipe are filled with waterproof mortar, and the waterproof mortar is plugged into full full, and the triangular waterproof mortar is put out at last, the width is kept in 5-6cm.

五、钢筋混凝土检查井场地防护注意事项：
Five. Precautions for site inspection of reinforced concrete inspection wells:
1、卸车时应轻起轻放，存放地地面平整，防止井室倾斜和倒塌。
1, when unloading, light lifting should be carried out, and the floor of the storage site should be leveled to prevent the inclination and collapse of the well chamber.
2、应使用专业吊钩，运用吊装孔进行卸车。
2, professional hooks should be used and unloading holes should be lifted by lifting holes.
3、堆放有序，提前规划，避免多次搬运，避免造成额外损坏。
3, stacking orderly, advance planning, avoid multiple handling, avoid causing additional damage.
4、突遇极端天气时做好防护工作。
4, in the event of extreme weather, do a good job of protection.
