简述辐射井施工工艺

A Summary of Construction Technology of Radial Tubewells

为有效利用地下水,目前多采用大口径辐射集中取水。集水井主要采取沉井法和现浇逆作法进行施工;辐射管井主要采用锚孔施工机械或液压机械岩心钻机水平钻进成孔工艺施工。

At present, large diameter radial tubeweUs are used for taking water intaking in order to utilize usefully groundwater. Sumpl wells are constructed by means of drop shaft sinking and cast - in - place backout methods. Radial tubeweUs are constructed with anchor eye drilling or machine horizontal drilling.
