Abstract

The invention provides a buried pipe drainage device in cropland on an unsaturated condition and a laying method of the buried pipe drainage device. The buried pipe drainage device comprises a buried pipe and a filtration sand layer; the buried pipe is horizontally arranged in soil; drainage holes are formed in the buried pipe; and the filtration sand layer is arranged in the soil, and covers the buried pipe partly, and is located on the buried pipe. With the adoption of the technical scheme, the problem in the prior art that water can not be drained into the buried pipe easily when soil water is in an unsaturated state is solved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an underground pipe drainage device and a laying method under unsaturated farmland conditions. Background technique [0002] After many years of drip irrigation in saline-alkali farmland in Xinjiang, the salt in the soil tends to accumulate at the wet peak of the lower root layer (40-60 cm), which increases the risk of secondary salinization and seriously affects the sustainable use of farmland. How to eliminate the salt accumulated near the root zone of crops under long-term drip irrigation has become an important problem to be solved in the development of local agriculture. [0003] In the soil improvement engineering technology, the concealed pipe is applied to the improvement of drip irrigation saline-alkali land due to its small footprint, convenient and fast construction. However, the traditional underground pipe technology mainly buries the underground pipe under...
