在设计供水量较大之浅井时,单靠浅井本身湧水量往往不敷应用,多半需设集水沟渠等建筑物,以便取得较为丰富的水源,但集水沟渠的方式受地质和施工等条件限制;故近年来国內外广泛的修建了带辐射形集水管的水源井,该种形式水源井,对增加湧水量收效很大,据统计,在同样的水文地质条件和供水量时,辐射井的建筑造价比一羣管井平均低15～30％;因此,用辐射井集取地下潛流,无论在挖掘企业原有井的潛力方面,或用于农田灌溉方面都是很有利的. In the design of shallow wells with large water supply, the inflow of water alone is often not enough for shallow wells. Most of them are required to have structures such as gully drains in order to obtain more abundant water sources. However, the ways of drains and ditches are affected by geological conditions and construction conditions Therefore, in recent years, a wide range of water source wells have been built both domestically and internationally. The water source wells of this type have a great effect on increasing water inflow. According to statistics, at the same hydrogeological conditions and water supply, The construction cost is 15-30% lower than that of a group of tube wells. Therefore, the use of radiation wells to collect underground submarine streams is very beneficial in terms of the potential of the existing wells in the enterprise or in farmland irrigation.
