Abstract

The invention provides an observation hole drilling device for a water pumping test, and belongs to the technical field of water pumping test drilling. The observation hole drilling device for the water pumping test comprises a base, a drilling machine and a splash-proof material conveying mechanism. The bottom of the drilling machine is fixedly connected with the top face of the base, a rotary packing auger is fixedly connected with the output end of the drilling machine, the bottom end of the rotary packing auger slidably penetrates through the base, and the splash-proof material conveying mechanism comprises electric push rods, a splash-proof cover, a hanging bracket, a motor, a driving wheel, a driven wheel, a transmission belt and a scraper. The electric push rods are fixedly connected to the two sides of the base, the output ends of the electric push rods are fixedly connected with the two sides of the top face of the splash-proof cover, a through hole is formed in the top of the splash-proof cover, the bottom end of the rotary auger slidably penetrates through the through hole, and a buffering cushion is arranged at the bottom of the splash-proof cover. According to the observation hole drilling device for the water pumping test, stones and other hard objects thrown out by a storage device can be blocked, and the hard objects are prevented from damaging equipment and injuring operators, so that the drilling safety of the device is improved.

Description

technical field [0001] The present application relates to the technical field of pumping test drilling, in particular to an observation hole drilling device for pumping test. Background technique [0002] The pumping test includes pumping a certain amount of water from the pumping well and measuring the change of groundwater level at different times in the observation well at a certain distance. The observation data is analyzed by using various groundwater flow theoretical formulas or graphical methods to analyze the results of the pumping test. In order to calculate hydrogeological parameters, 2 to 3 observation holes should be arranged perpendicular to the flow direction of groundwater on one side of the pumping hole. At present, when opening observation holes, the rotary auger of the drilling machine rotates and inserts into the ground, and the rotary auger throws the soil outward while rotating at a high speed. Hard objects will damage the equipment and bring unsafe hid...
