What is the leak-proof method for wells?

Considering the particularity of seepage well, the waterproof effect is not good. In order to make better use of well water, the following is the construction scheme of seepage well:

1, trench excavation:

(1) Determine the location of trench excavation according to the measurement results. The trench is excavated manually by a small excavator, and the trench earthwork is transported with the excavation.

(2) Determine the trench excavation section according to the drawing design.

(3) When the excavator is used for construction, a soil layer with a thickness of 30cm should be reserved, and manual bottom cleaning is not required. When the earthwork is excavated close to the design elevation, the elevation control pile should be driven into the groove to control the excavation depth and prevent the excavation from being too shallow or overbreak.

(4) In the process of trench excavation, we should know the soil quality, groundwater level and original pipelines in time, and take protective measures in time.

(5) The allowable deviation of tank bottom elevation is 20 mm. ..

(6) The excavated pipe trench shall be provided with warning signs in time and closed for management to prevent accidents.

2, seepage well masonry. After the straightness, stability and elevation of the seepage well are checked and confirmed, masonry can be carried out.

3, seepage well requirements.

(1) The size of seepage well meets the design requirements.

(2) The bottom hole foundation shall be poured at the same time as the pipeline foundation.

(3) The nozzle of the seepage well connected with the circular pipe should be flush with the inner wall of the well, and the pipe should be tight and watertight when passing through the wall. (4) Plastering of internal and external walls of masonry seepage wells shall be carried out in layers.

(5) After the seepage well is laid or installed to the specified elevation, the well ring shall be poured or installed in time, and the manhole cover shall be covered.

(6) The technical deviation of seepage well should meet the requirements.
