Collector pipe embedding structure for saline-alkali land soil improving

Abstract

The invention discloses a collector pipe embedding structure for saline-alkali land soil improving, and belongs to the technical field of collector pipes. The collector pipe embedding structure for saline-alkali land soil improving comprises a saline-alkali land layer, a macadam filtering layer is arranged at the bottom of the saline-alkali land layer, a gravel layer is arranged at the bottom of the macadam filtering layer, and a drainage pipe is arranged at the bottom of the gravel layer in an inclined manner. According to the collector pipe embedding structure for saline-alkali land soil improving, the macadam filtering layer is arranged, so that drained saline is initially filtered, and sediment entering collector pipes is reduced; the gravel layer is arranged, so that the drained saline is secondarily filtered, solid particles in the drained saline are reduced, meanwhile, the pressure reducing and buffering effects are achieved, and the pressure of the collector pipe and the drainage pipe is reduced; the drainage pipe is arranged, so that collected water is drained to a collector well through the drainage pipe in a concentrated manner, and losses of the water resource are reduced; and tiny water collecting holes are formed, so that water which is not collected by water collecting hoppers is collected by the tiny water collecting holes, and losses of the water resource are reduced.

Description

technical field [0001] The invention relates to the technical field of water collection pipes, in particular to a structure of buried water collection pipes for soil improvement in saline-alkali land. Background technique [0002] At present, in saline-alkali land areas, facing problems such as lack of fresh water resources, groundwater salinization, and high groundwater levels, soil water and salt conditions are the main factors affecting plant growth. Establishing a water-saving and efficient irrigation system has become the key to improving saline-alkali land. In saline-alkali land Among improvements, salt reduction and watering of plants by flood irrigation are still very common. Due to the low cost of flood irrigation and the simple operation process, flood irrigation can easily cause waste of water resources, and untimely drainage will cause groundwater to rise and cause secondary salinization of the soil. Therefore, the collection and reuse of water resources is parti...
