Description

Water taking device based on deep confined water observation well
Technical Field
The utility model relates to a groundwater surveys technical field, especially relates to water intaking ware based on deep confined water observation well.
Background
The construction site often has multilayer groundwater, and the top layer is usually dive, and the deep layer is because of covering different thickness water barriers and bearing formation multilayer confined water. Along with the continuous deep of human activities in the underground range, such as pumping and lowering confined water in deep foundation pit construction, heating by adopting deep confined water, recharging the confined water for controlling ground settlement and the like, the human activities have a profound influence on the water level and the water quality of the deep confined water.
One of the jobs of the geotechnical engineering investigation profession is to provide hydrogeological parameters of diving and confined water for design and construction. The measurement of the water level of each layer of confined water has already become a conventional requirement in the exploration stage, and the analysis of the quality of the confined water is gradually changed from an unconventional project to a conventional project due to the change of environmental factors.
If the confined water of a specific aquifer needs to be taken, the confined water of the aquifer needs to be separated from the aquifers on the upper part. A medium coarse sand permeable layer is filled between a water taking well and a drilling well in the depth range of the aquifer, and cohesive soil is filled above the top of the aquifer for water isolation.
In the exploration stage, the underwater water is generally taken in a drill hole, the diameter of the drill hole is generally 91mm, and corresponding water taking devices are more. Because the water intake device needs to be separated from each aquifer at the upper part, the confined water of a specific aquifer is taken, and if a conventional water taking device is used, a larger hole needs to be opened again to form a confined water taking well. If the pressure-bearing water well is made in the existing drilling well, the diameter of the pressure-bearing water well is only 50mm.
The current situation is that the pressure-bearing water wells with the diameter of 50mm are generally used as pressure-bearing water level observation wells in the exploration stage. When the confined water has great influence on construction, the large-diameter water pumping test hole is opened for hydrogeology special investigation, and the well can be additionally used for taking water. However, the pumping test well is not suitable for a pumping test, and the pumping test is expensive, so the pumping test well can not be used as a conventional confined water pumping well. If a suitable pressure-bearing water taking well is opened again, extra cost is needed, and the cost is higher.
At present, a water taking device-a Beller tube in a current confined water observation well is also available. The Beller tube is small in size and convenient to carry, has the pipe diameter of 40mm, is a hard pipe, has different lengths of 950mm, and is suitable for taking water in a pumping well with a larger diameter. If water is taken from the confined water observation well, the Beller tube is often not perpendicular to the well or blocked due to foreign matters because of relatively large diameter, or falls into the deep well to cause equipment loss because the foreign matters influence the rope breakage. Meanwhile, the amount of water taken by the Belleville tube each time is limited, and 1000ml of water sample can be taken at least twice.
Therefore, the technical personnel in the field aim to invent the pressure-bearing water taking device with lower implementation cost, smaller size, large water taking amount and stronger applicability so as to make up the defects of the prior art.
