检查井井盖安装不规范产生的原因

Cause of non standard installation of well cap for inspection well

原因1：目前的道路工程及管线工程的施工规范中没有铸铁检查井井盖安装的标准工艺，安装方法多种多样。

Reason 1: there is no standard technology for the installation of cast iron inspection wells in the current construction specifications for road works and pipeline projects, and there are various installation methods.

原因2：操作工人在井盖安装施工往往独立作业，有较强的随意性。

Reason 2: operators in the manhole cover installation construction often independent operation, has a strong randomness.

原因3：安装过程中，缺少检查监督环节；安装完成后，质量不易检查，有无隐患不易判断。

Reason 3: in the installation process, there is a lack of inspection and supervision links; after installation, the quality is not easy to check, and whether there is hidden trouble is not easy to judge.

原因4：有不少施工单位不清楚排水规范的井盖安装规定.

Reason 4: many construction units do not know the drainage standards of the manhole cover installation requirements.

加筋检查井井盖施工工艺

Construction technology of reinforced check well cover

原理：通过受力转移，实现井圈与井筒脱离，外力作用通过井圈以及井圈底座可将大部分路面荷载传递到四周道路路面结构层面。同时，使井圈与四周柔性路面结构形成一个有机的整体，避免不均匀沉陷。

Principle: through the transfer of force, the wellbore and wellbore are separated from the well, and the external force can transfer most of the pavement load to the pavement structure level of the road around the road through the wellbore and the wellbore base. At the same time, the structure of the shaft and the flexible pavement forms an organic whole to avoid uneven settlement.

方法：在检查井井口位置加设现浇钢筋混凝土井圈(配筋采用梯形截面，详见构造图)。

Methods: the cast in place reinforced concrete well ring is added at the wellhead location of the inspection well.

适用：本施工工艺适用于市政新建道路工程及市政工程现况道路检查井改造。

Application: this construction technology is applicable to the reconstruction of road inspection wells in the new road works and municipal works.
