Embodiment Construction

[0022] Such as figure 1 As shown, the present invention provides a kind of method of observation multilayer groundwater level, comprises the steps:

[0023] (1) drill a hydrogeological hole 3 at the position to be measured with multilayer groundwater; The depth of drilling makes the hydrogeological hole 3 penetrate through the multilayer groundwater, the aquifer (1, 4, 6) of the multilayer groundwater There are aquitards (2, 5, 7) between and above the top aquifer;

[0024] (2) Put the same water measuring pipes (8, 9, 10) as the layers of the aquifer in the hydrogeological hole, that is, N+1 water measuring pipes, and the water measuring pipes (8, 9, 10) include none Seam steel pipes (8-1, 9-1, 10-1) and water filter pipes (8-2, 9-2, 10-2) connected to the lower end of the seamless steel pipe, the pipe wall of the water filter pipe has multiple A permeable hole (8-3, 9-3, 10-3);

[0025] First place the first water measuring pipe, the length of the filter pipe of the first...

Abstract

The invention discloses a method for observing the water level of multiple layers of underground water, and belongs to a hydrogeological exploration technology. The method comprises the steps that 1, a hydrogeological hole is drilled at a to-be-observed position with multiple layers of the underground water; 2, test pipes of which the number is the same as the layer number of water-bearing layers are put into the hydrogeological hole, cobbles are filled in hydrogeological hole segments corresponding to all the water-bearing layers, then concrete is filled in hydrogeological hole segments corresponding to water-resisting layers over the water-bearing layers, the test pipes comprise seamless steel pipes and strainer pipes connected to the lower ends of the seamless steel pipes, and the pipe walls of the strainer pipes are provided with multiple water permeating holes. According to the method for observing the water level of multiple layers of the underground water, the water level of multiple layers of the underground water can be simultaneously observed through the same hydrogeological hole, the construction difficulty is small, and the steps are simple.

Description

technical field [0001] The invention relates to hydrogeological observation technology, in particular to a method for observing multi-layer groundwater levels. Background technique [0002] The groundwater table is the elevation of the water surface in an underground aquifer. According to the drilling observation time, it can be divided into initial water level, stable water level, water level in wet season, water level in dry season, and water level before freezing. [0003] The main reasons for the decline of the groundwater level are: one is: human factors, mainly the overuse of human beings. The second is natural factors. Such as the elevation of the terrain caused by the earthquake, the sinking of the underground river, etc.; the diversion of the river; the change of the climate, etc. [0004] Rising groundwater levels have both natural and man-made causes: [0005] A short-term increase in rainfall, changes in the direction of underground rivers in karst areas, and...
