[0025] 2. Example 2
[0026] An example of the structure of the infiltration water intake project of the present invention selected and built on the bank of the Daning River ( figure 2 )
[0027] Catchment well 1 was built on the bank of the Daning River, crossing the loose accumulation layer and inserting the bottom of the well into the bedrock a34m (total well depth 46m). Two rows of 12 fan-shaped controlled directional infiltration holes 3 are arranged 2m and 3m away from the bottom of the well to the sand and gravel layer b under the riverbed, with the depths ranging from 320-480m, and the control sand and gravel layer b has an area of 54000m 2. Due to the good drilling conditions for rock formations, most of them do not use synchronous pipe wall protection or reduce diameter treatment, so the drilling process is simpler. After the hole is formed, the filter 5 is first placed into the sand and pebble layer from the end of the hole, and then the filter 5 is installed accordi...
