An underground concrete structure of a multifunctional lysimeter pit

Abstract

The invention discloses a multifunctional evapotranspiration test pit underground concrete structure. The multifunctional evapotranspiration test pit underground concrete structure comprises a vertical corridor, a computer monitor room, an underground control hall, test pits, an underground observation gallery, a weighting type lysimeter system and an underground water supply and discharge system. The vertical corridor leads to the computer monitor room and the underground control hall. The computer monitor room is located at a half storey position of the vertical corridor, and the lower portion leads to the underground control hall. The underground observation gallery is connected with the underground control hall. The test pits are located on the two sides of the observation gallery. The weighing type lysimeter system is arranged at the tail end of the observation gallery. The multifunctional evapotranspiration test pit underground concrete structure is convenient to construct and reliable in performance, the computer monitor room located at the half storey position of the vertical corridor can achieve collection of measured soil parameter data and artificial monitoring of the underground control hall; the weighing type lysimeter system is arranged in a basement, measuring is not interfered with the outside wind and rain weather, and the structural expandability is high.

Description

technical field [0001] The invention relates to a multifunctional lysimetry pit device, in particular to an underground concrete structure of a multifunctional lysimeter pit, belonging to the fields of hydraulic engineering and agronomy. Background technique [0002] The lysimeter pit is a structure that isolates a part of the soil in the field, and calculates the water balance of the soil in the pit by measuring and calculating the water balance elements, so as to estimate the water demand of the crop. At present, most irrigation test stations in my country use lysimeter pits as the main tool for observing the water demand of dry crops. In order to ensure the accuracy and representativeness of the lysimeter test results, the quality of the test pit structure is one of the most basic and critical conditions. The problems existing in the current test pit structure mainly include: the waterproof performance of the pit wall material is not good, and the leakage is serious; the...
