Introduction to the plugging method of sewage wells
First, the use of lime for treatment.
Lime is a commonly used sewage well plugging material, which has a good drying and hygroscopic effect, can effectively absorb the water in the well, and reduce the humidity of the sewage well. Here's how:
1.Clean up the debris and sludge in the sewage well to ensure that the well is clean for subsequent construction.
2.Sprinkle lime evenly around the wellhead at a dosage of about 20 kg.
3.Spread a layer of plastic sheeting or cement bag on top of the lime to prevent the rain from washing away the lime.
4.Add an appropriate amount of water to the plastic sheet or cement bag to allow it to absorb and expand until the wellhead is completely closed.
5.After waiting for 24 hours, open the wellhead and check the plugging effect. If the plugging is not tight, you can sprinkle lime again and repeat the above steps.
Second, the use of cement mortar for plugging.
Cement mortar is a material with high strength and good durability, which is suitable for plugging sewage wells. Here's how:
1.Clean up the debris and sludge in the sewage well and rinse it with water.
2.Apply a layer of cement mortar to the bottom and wall of the well to ensure that the application is uniform and flat.
3.After the cement mortar is dry, the second layer of cement mortar is applied to strengthen the plugging effect.
4.Add an appropriate amount of water to the cement mortar to make it fully absorb water and expand until the wellhead is completely closed.
5.After waiting for 24 hours, open the wellhead and check the plugging effect. If the plugging is not tight, you can apply cement mortar again and repeat the above steps.
3. Use the plugging king for plugging.
Plugging King is a fast-solidifying, high-strength material, which is suitable for rapid plugging of sewage wells. Here's how:
1.Clean up the debris and sludge in the sewage well and rinse it with water.
2.Mix the plugging king according to the proportion on the manual, and stir well.
3.Quickly apply the plugging king to the leakage of the sewage well to ensure that the application is uniform and flat.
4.After waiting for the plugging king to dry, open the wellhead and check the plugging effect. If the plugging is not tight, you can apply the plugging king again and repeat the above steps.
The above are three common sewage well plugging methods, lime, cement mortar and plugging king all have different characteristics and scope of application. In practice, it is necessary to select the appropriate blocking method according to the specific situation. At the same time, in order to ensure the plugging effect and service life, it is necessary to pay attention to the construction quality and later maintenance.
