Installation Tips for manhole covers on sewage wells

1、为了增强井圈受压强度，增加井圈底面的座落面积，安装井圈时，井体内径不得大于井圈内径。

1. In order to enhance the compressive strength of the wellbore and increase the area at the bottom of the wellbore, the inner diameter of the wellbore should not be larger than the inner diameter of the wellbore when the wellbore is installed.

2、井体台的结构必须为砖混结构，必须坚固平衡，形成结构力后，方可安装井圈和箅座。

2. The structure of wellbore must be brick-concrete structure, and must be solid and balanced. After forming structural force, wellbore and grating can be installed.

3、安装箅座时，箅座底面不得悬空。可以参考井圈的安装方法。

4. When placing the wellbore and the grate, the concrete at the bottom of the wellbore and the grate (the thickness of concrete must not be less than 30 mm) should be placed in place before solidification, and the vibrating wellbore should be compacted or knocked, so that the wellbore and the concrete are closely combined to increase the contact area between the wellbore and the grate and the wellbore.

5、产品安装后的载重量不得超出产品规定的承载能力。

5. The load capacity after installation shall not exceed the load capacity specified by the product.

6、上盖前要清除井圈内的杂物，避免井盖井盖指南针与井圈点接触。

6. Remove the debris in the well before the top cover, and avoid the contact between the manhole cover and the well.
