100m Geological Exploration Hydraulic Engineering Drilling Rig
XY-1 Water Well Drilling Rig Information
XY-1 Small hydraulic core drilling rig is a kind of small-scale sampling and drilling equipment widely used in plains, mountainous areas and areas with inconvenient transportation and energy. It has the advantages of compact structure, small occupied area, light weight and convenient movement. It is suitable for geological sampling exploration, geological core drilling, small grouting holes, blasting holes, grouting holes, etc. in railway, water conservancy, water wells, construction projects and outdoor mountain areas. Diamond, composite and alloy bits can be selected for drilling according to different formations.

XY-1 Water Well Drilling Rig Features
XY-1 drill rig is used to survey and exploration, geophysical prospecting, road and construction exploration, punching blastinghole, etc.
Used for general investigation, geophysical exploration, high-way and building construction, and blast-hole drilling etc.
1. With hydro-automatic feeding device, and high drilling efficiency.
2. Designed with hydro-chucking unit instead of slips to ensure drilling from stop when changing pipes.
3. Close levers, convenient to operate, safe and reliable operations.
4. Compact in structure. All the drill, water pump and diesel engine installed on one base frame result in space-saving.
Light in weight, easy disassembling for transportation and applicable to working conditions in plain and mountain areas
What is the construction technology of de watering well?
Well point measurement and positioning → hole digging and casing embedding → drilling rig in place → drilling → hoisting well pipe → back-filling filter material (coarse sand or gravel) between well pipe and hole wall → hole washing → drainage pump in well pipe and installation of pumping control circuit → trial pumping → normal operation of well point → de watering completion, pipe pulling → well sealing.
The de watering shall be carried out 20 days before the excavation of the foundation pit, so as to drain the stagnant water in the stratum in advance, reduce the groundwater level, improve the self stabilization capacity of the soil layer, and smoothly carry out the anhydrous operation. During the de watering operation, the water level observation of each well shall be done well, and the change of the head of the confined aquifer shall be mastered in time
