| 1、检查井应设在管道交汇处、转弯处、管径或坡度改变处、跌水处以及直线管段上每隔一定距离处。 1. The inspection well shall be set at the intersection, turning, pipe diameter or slope change, water drop and every certain distance on the straight pipe section. 2、检查井在直线管段的最大间距应根据具体情况确定 2. The maximum spacing of inspection wells in the straight pipe section shall be determined according to the specific situation 3、检查井的流槽检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 3. Chute of inspection well （1）井底宜设流槽。 (1) Flow channel should be set at the bottom of the well. （2）污水检查井流槽顶可与0.85倍大管管径处相平，雨水(合流)检查井流槽顶可与0.5倍大管管径处相平。 (2) The top of flow channel of sewage inspection well can be level with 0.85 times of large pipe diameter, and the top of flow channel of rainwater inspection well can be level with 0.5 times of large pipe diameter. （3）流槽顶部宽度宜满足检修要求。 (3) The width of the top of the chute should meet the maintenance requirements. （4）在管道转弯处，检查井内流槽中心线的弯曲半径应按转角大小和管径大小确定，但不宜小于大管管径。 (4) At the turning point of the pipeline, the bending radius of the center line of the chute in the inspection well should be determined according to the size of the turning angle and the diameter of the pipe, but should not be less than the diameter of the large pipe. 4、交汇井交角不得小于90°，主管与支管内壁距离不得小于300mm。 4. The intersection angle of the intersection well shall not be less than 90 ° and the distance between the main pipe and the inner wall of the branch pipe shall not be less than 300 mm. 5、检修室高度在管道埋深许可时一般为1.8m,污水检查井由流槽顶起算，雨水(合流)检查井由管底起算。 5. The height of the maintenance room is generally 1.8m when the buried depth of the pipeline permits. The sewage inspection well is calculated from the top of the chute, and the rainwater (combined) inspection well is calculated from the bottom of the pipe. 6、在污水干管每隔适当距离的检查井内，需要时可设置闸槽。在排水管道每隔适当距离的检查井内和泵站前一检查井内.宜设置沉泥槽，深度宜为0.3～0.5m。 6. In the inspection well of sewage main pipe with proper distance, sluice slot can be set when necessary. In the inspection well of drainage pipeline with proper distance and in the inspection well in front of the pump station, it is better to set up the sedimentation tank with the depth of 0.3-0.5m. 7、接入检查井的支管(接户管或连接管)管径大于300mm时，支管数不宜超过3条。 7. When the diameter of the branch pipe (connecting pipe or connecting pipe) connected to the inspection well is more than 300 mm, the number of branch pipes should not exceed 3. 8、排水井盖选用的型号、材质应符合: 8. The model and material of drain well cover shall meet the following requirements: （1）行业标志明显。位于车行道的检查井，应采用具有足够承载力和稳定性良好的井盖与井座。 (1) The industry mark is obvious. The manhole cover and seat with enough bearing capacity and good stability should be used for the inspection well located in the roadway. （2）位于路面上的井盖，宜与路面持平；位于绿化带内的井盖，不应低于地面。 (2) The well cover on the road surface should be level with the road surface; The well cover in the Green Belt should not be lower than the ground. |
