Problems solved by technology

In April 1978, the "Hydrogeological Handbook" of Geological Press and the "Handbook of Water Supply and Drainage Design Volume 3" of China Architecture Press in 1996 introduced the radiation well structure. For the loose accumulation layer in the direction, the steel perforated pipe with a length of no more than 50m is manually driven into the water intake and collection; it is only suitable for the exploitation of groundwater in the loose medium and coarse sand accumulation layer, and the control range of the water intake area Limited, unable to improve the quality of source water taken
The natural filter bed seepage well is a Chinese invention patent (ZL93110953.1) authorized and announced on February 12, 1997. It is composed of radiated seepage holes in the sand and pebble layer; it expands the water intake range of the large well on the basis of the radiation well, and

Example Embodiment

[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...

Abstract

The present invention relates to underground water taking and collecting method, and is new engineering structure for taking percolation water. The present invention features that the collecting well is embedded into base rock stratum for at least 5 m, controlled directional percolation holes are drilled into grit stratum under the base rock stratum around the well, and filters are set in the hole parts corresponding to the water bearing stratums. The said engineering structure makes the taken underground water need no further processing in the water producing system, and has the merits of both radiation well and natural filtering bed percolation well, including simple engineering structure, being safe and reliable, no damage to ecological environment, etc.

Description

1. Technical field [0001] The invention belongs to methods for water intake and water collection, and in particular to groundwater water intake and water collection methods. 2. Background technology [0002] There are many water intake technologies for groundwater, but the existing technologies that can utilize the natural filtering effect of the formation and have similar technical conditions are the most typical ones are the water intake technology of radiation wells and the water intake technology of natural filter bed seepage wells. In April 1978, the "Hydrogeological Handbook" of Geological Press and the "Handbook of Water Supply and Drainage Design Volume 3" of China Architecture Press in 1996 introduced the radiation well structure. For the loose accumulation layer in the direction, the steel perforated pipe with a length of no more than 50m is manually driven into the water intake and collection; it is only suitable for the exploitation of groundwater in the loose me...
