Tubewell ke liye bore ka gehraai bahut kuch is baat par nirbhar karta hai ki aap kahaan rehte hain aur wahan paani ki sath kya hai. Aur bhi kai aur factors hain jo bore ki gehraai ko prabhavit karte hain, jaisa ki:
1. Bhumigat Jal ka Star (Underground Water Level) - Agar aapke ilaqe mein bhumigat jal ka star gahara hai, toh bore ko bhi usi hisab se gahara karna hoga.
2. Paani ki Maang - Agar aapko zyada paani ki avashyakta hai, toh bore ko gahara karna hoga taaki paryaapt paani prapt ho sake.
3. Mitti ki Kisam - Kuch mittiyaan zyada resilo hoti hain aur paani ko rok leti hain. Aise maamle mein bore ko aur gahara karna padta hai.
4. Khanan ya Bhari Udhyog - Agar aas-paas khanan ya bhari udhyog chalu hai, toh woh bhumigat jal ko kam kar sakte hain aur bore ko aur gahara karna padega.
Aam taur par, grame-en ilaaqon mein tubewell ke liye 100 se 300 fit tak ka bore kar liya jaata hai. Lekin shehri ilaaqon mein bhumigat jal ka star niche hone ki vajah se 300 se 500 fit tak ka bore karvana padta hai bahut baar. Sahi gehraai ke liye, aap ek bore karvane vale engineer se salaah le sakte hain.
points about boring/drilling for agricultural tubewells:
- Tubewells are wells drilled into underground aquifers to extract groundwater for irrigation purposes in agriculture.
- Boring or drilling a tubewell involves using a drilling rig to drill a borehole or well into the aquifer layer underground.
- The depth of the borehole depends on the depth at which water-bearing soil strata or aquifers are available. In many agricultural areas, tubewells may need to be 100-300 feet deep.
- During drilling, a casing pipe is installed to line the borehole and prevent collapse of the sides. Slotted casing/screens are used at the aquifer level to allow water inflow.
- After drilling to the required depth, a submersible pump is lowered into the tubewell to lift the groundwater for irrigation.
- Factors like aquifer depth, soil types, pump sizing etc. need to be considered for optimum tubewell design and sustainable extraction.
- Tubewells enable access to groundwater for irrigation, which is critical for agricultural productivity, especially in areas with water scarcity.
Let me know if you need any other details about the process and purpose of boring tubewells specifically for agricultural irrigation.
