Abstract
To ensure the domestic water and landscape water supply requirements of Hejin Sakura Valley Scenic Area, the water supply scheme of the artificial lake and scenic spot domestic water consumption assessment machine is optimized. Firstly, in view of the water resources situation in the area where the cherry blossom valley garden scenic spot is located, the necessity of pumping groundwater is pointed out; Secondly, combined with the basic information of hydrogeology and mountainous terrain, a scheme for pumping water supply from natural pipe wells is proposed; Finally, relying on FLAC3D software, three different pipe diameter pumping well models of 600mm, 700mm and 800mm are established, three-dimensional jet field analysis is carried out, and the optimal layout scheme of pipe diameter and position of pipe well is given. Studies have shown that the larger the well diameter, the greater the outlet flow rate, and the water output can be increased by 50~80m3/d for each 100mm tube well; The number of tube wells arranged is about 6, and it is recommended that a sufficient distance should be maintained between wells; The demand for pipe wells with different apertures varies between 1 and 2 mouths. The results of this paper can provide guidance for the construction of gardens in central China to solve the problem of water supply, and support and serve the construction of garden landscape.
