Zaduo County Zhaduo Village In Qinghai Province Drink Water Engineering Supply Scheme Research

Zhagou village site from north to south in post-disaster restoration andreconstruction for the ancient,Segu Long Ma Datan Sezha temple Jire Long WaiQing Ka Guo Xia Ka belong to Sa Hu Teng town crier manifolds of yushu prefecturecounty jurisdiction. Papers with regional hydrogeology and water supply scheme asthe research object, research the distribution of groundwater, replenishment andsurface water runoff, analyzing hydrogeology drilling results, atmospheric infiltrationmethod and cross section method to calculate natural resource of groundwater, thefollowing conclusions:(1) Through regional hydrogeology research, combined with the field surveydata, it is concluded that the study area of groundwater occurrence conditions anddistribution of: the study area is located at an elevation of4300m above themountains, development (rock) layer of permafrost, weathering is strong, and this areaformation fracture, promotes the infiltration of atmospheric precipitation, form thefreezing layer water, winter is given priority to with solid state occurrence, summer isgiven priority to with liquid; Mountains occur in bedrock fissure, mountain valleyoccurrence in the loose rock pore. Zhage yun valley widely distributed quaternaryunconsolidated sediments, groundwater types for loose rock pore water, surface waterand atmospheric precipitation and other types of lateral recharge of groundwater, theaquifer lithology for blunt pluvial argillaceous sandy gravel and moraine gravel, mudrush pluvial formation aquifer thickness thin, generally the thickness of5-15m,particle bulky, strong permeability, poor aquosity, water content in general.(2) Through the dynamic observation of surface water, such as large single-holepumping testing of hydrogeological exploration, we initially planned water supplywater source of the hydrogeological conditions, combined with atmosphericinfiltration method and cross section method to calculate the water source of watersupply of natural resource of groundwater, water supply are obtained.The Guo Xia Ka settlements and Jire Long site by the hydrogeology drillingZK01ZK04revealed that no underground water level, thus unfavorable useDaKouJing water supply way; The ground survey, zone ditch Zhage yun each branchlander are seasonal rivers, springs for seasonal spring, winter basic frozen or dried upwithout water, there is no guarantee that winter water, local residents can’t meet thedemand of the residents drinking water supply, seasonal water diversion water supplyin the short term can be selected, after waiting for site for power from the river water;Sezha temple site and Wai Qing Ka site the hydrogeology drilling ZK05andZK06reveal, buried depth of ground water level is9.40m and6.72m respectively, theamount of water less than10m3/d, down deep, only as deep as10-15m2minutes,aquifer thickness thin, groundwater recharge is slow, water is difficult to recover within24hours, unable to meet the demand of residents drinking water supply inwinter. Therefore, unfavorable DaKouJing way water supply. Sezha Temple siteresidents lead springs in color as the water of life, the spring after investigation asbedrock fissure water, because the spring has been lead to local residents, not thespring flow rate measurement. According to access the spring water all year round,and basically met the Sezha temple site of100people living water;Segu Long Ma Datan site according to the ZK02ZK03borehole data: burieddeep underground water level of2.720m2.720m. Aquifer thickness of about5.38m3.743m, respectively, of aquifer lithology for blunt diluvial gravel stone, small shalecontent, permeability coefficient of16.515m~3/d32.185m~3/d. By the above twokinds of calculation, the524.35m3/d,695.20m~3/d as evaluation proposed abovewater natural recharge of groundwater. Well meet the demand of the residentsdrinking water supply, so the color of ancient, Segu Long Ma Datan site can useDaKouJing way of water supply, solve the problem of local residents living waterdifficult.(3) Through the source of water supply hydrogeological research results,determine the scheme of water supply.Segu Long Ma Datan site can be directly artificial sinking water supply, waterassured;Sezha temple Jire Long Wai Qing Ka Guo Xia Ka site of settlements in thetower on the bedrock mountains, river water is difficult, according to the result ofwater proof research without use of groundwater, but there is a seasonal springexposed, guaranteed water in summer and autumn, winter and spring season twowater volume is small, preliminary built lead spring type permeability reservoirs takesegmented, time-sharing water supply, drainage channels late site after the powersupply for drawing from the river to the reservoir.Water quality by the health and epidemic prevention departments by the sensoryproperties and general chemical indicators, toxicology, microbial testing, the resultsaccord with GB/T3838-2002"standard of surface water environment quality"water class water quality requirements, can be used as a drinking water source water,just for source water purification (precipitation, filtration, disinfection treatment. Afterprocessing should reach GB5749-2006"drinking water health standard" requirement,to ensure the safety of drinking water.
