Precipitation device for sand soil layer foundation
The invention relates to a dewatering device for a sand soil layer foundation, which comprises a well body, and the well body sequentially comprises at least one standard section and a water passing section from top to bottom; the standard knot comprises a second standard knot steel cylinder and a first standard knot steel cylinder; the water passing section comprises a first water passing section steel cylinder, a third water passing section steel cylinder and a second water passing section steel cylinder which are concentrically arranged in sequence from outside to inside; a plurality of water passing holes are formed in the cylinder wall of the first water passing section steel cylinder, water filtering gravel is filled between the first water passing section steel cylinder and the third water passing section steel cylinder, and a water passing pipe is arranged between the third water passing section steel cylinder and the second water passing section steel cylinder. According to the dewatering device, the well body is jointly formed by the standard knots and the water passing knots, a supporting structure is formed through the steel cylinders, the water passing structures are arranged in the water passing knots (each water passing structure is composed of the corresponding water passing hole, the corresponding water filtering gravel and the corresponding water passing pipe), it is guaranteed that underground water can successfully enter the well body, and meanwhile hole collapse in a sand soil layer with the large water content can be prevented.
本发明涉及一种用于砂土层地基的降水装置，包括井体，所述井体从上至下依次包括至少一节标准节和一节过水节；标准节包括第二标准节钢筒和第一标准节钢筒；过水节包括从外至内依次同心布置的第一过水节钢筒、第三过水节钢筒和第二过水节钢筒；第一过水节钢筒筒壁开设有若干过水孔，第一过水节钢筒和第三过水节钢筒之间填充有滤水卵砾，第三过水节钢筒和第二过水节钢筒之间配置有过水管。上述降水装置，采用标准节和过水节共同构成井体，通过钢筒形成支护结构，并且在过水节中配置过水结构(过水结构由过水孔、滤水卵砾和过水管组成)，保证地下水能够成功进入井体内的同时，还能可以防止含水量较大的砂土层中塌孔发生。
