Background
The micro-water test is a simple method for determining the hydrogeologic parameters of the aquifer by inducing the change law of the well water level with time through the instant increase (or decrease) of the micro-water amount in the well bore. In the micro-water test, the excitation modes commonly used for causing the change of the well water head are as follows: pneumatic, water injection or pumping, impact, etc. The pneumatic type device needs special equipment to seal the hole opening, needs pressurizing equipment such as a pneumatic pump and the like, needs more equipment and complex operation process, and needs conditions such as on-site power supply. The pumping or water injection excitation type operation is simpler, a certain volume of water is pumped (or injected) from the well hole in an instant manner by adopting pumping equipment or water injection equipment, and the water level recovery process is observed. However, the water head excitation process is influenced by the water pumping equipment, the size of the orifice, the duration of water injection and the like, so that the condition of 'instantaneous' excitation is difficult to realize, and the test precision is influenced to a certain extent. The impact type is to use a certain volume of solid matter (water head excitation device), instantly put the solid matter under the water surface of the well bore or instantly lift the solid matter from the water, promote the water level of the water surface of the well bore to instantly rise or fall by a certain height, and observe the water level recovery process. In general, the solid used in the method has a fixed volume, the specific gravity is more than 1, the impact is completed by manual operation when the solid enters into water or is extracted from water, and the requirement of 'instant' can be met in time. However, in the current impact micro water test, the water head excitation device (the solid matter) and the data acquisition device (the automatic water level gauge) are all independent devices, and the defects are that: 1. firstly, an automatic water level gauge is placed in a well hole, then a water head is excited to cause water level change, in the process, the water head excitation device is limited by the caliber of the well hole, the water head excitation device is easy to adhere to a cable of the automatic water level gauge in the impact or lifting process, the water pressure record of the automatic water level gauge is interfered, the water level observation precision is affected, and therefore test failure is often caused. 2. The water head excitation device is a cylindrical weight with fixed volume and weight, the length and the weight of the water head excitation device are not adjustable, the application range is small, and the water head excitation device is inconvenient to carry.
