Description
Technical Field
The utility model relates to an observation well that is used for oil tank oil impregnate to survey and sewage is collected belongs to filling station's construction technical field.
Background
The construction of the gas station is usually conducted by capital construction first, and then business can be conducted after the experience collection grids. The use departments cannot well supervise the whole process of corrosion prevention of oil tanks and pipelines constructed in gas stations. After long-term use, the oil tank may leak, mainly because: firstly, a construction party cannot treat the outer surface of the oil tank in place, the anticorrosive material cannot reach the grade, and hidden dangers are left due to construction reasons such as the damage of an anticorrosive coating caused by carelessness during construction and the like; secondly, the oil tank is buried underground for a long time, is in a humid environment and is corroded by the action of moisture, microorganisms and the like in soil; thirdly, the oil product in the oil tank contains water, the bottom of the oil product can be stagnant to separate out water after long-time use, the separated out water of different oil products is acidic or alkaline, punctiform corrosion is generated on the oil product in the oil tank, and perforation can be formed after a long time.
For the oil tank buried underground, the use department is inconvenient to monitor the use condition, so that it is necessary to build an observation well to monitor whether the oil tank leaks oil or not.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides an observation well that is used for oil tank oil impregnate to survey and sewage is collected.
The utility model discloses a following technical scheme can realize:
an observation well for oil tank oil seepage observation and sewage collection comprises a well hole and a pipeline, wherein the pipeline is positioned in the well hole, one end of the pipeline extends out of the well hole, a water filtering layer is arranged between the side wall of the pipeline and the side wall of the well hole, a plurality of water passing holes are formed in the part, close to the hole bottom of the well hole, of the pipeline, a bearing platform is arranged on the water filtering layer at the hole opening of the well hole, and the pipeline is positioned on the inner side of the bearing platform.
The water filtering layer is formed by filling gravel.
The particle size of the gravel is 10-30 mm.
The conduit is arranged coaxially with the wellbore.
The unilateral clearance between the pipeline and the well hole is 150 mm-250 mm.
And a filter layer is arranged between the pipeline and the water filtering layer.
The filter layer is made of geotextile or a stainless steel wire mesh.
The pipeline is made of hot-dip galvanized steel pipes, and 2 layers of epoxy asphalt paint are coated on the inner wall of the pipeline.
And 2, coating a zinc-rich primer layer on the inner walls of the water through holes.
The inboard of cushion cap is equipped with the well lid that is used for sealed pipeline upper end, and the outside at drainage layer top is equipped with the clay seal coat, and the inner wall of clay seal coat and the outer wall connection of cushion cap.
The beneficial effects of the utility model reside in that: whether the oil tank leaks oil or not can be regularly known through the observation well, loss stopping is facilitated in time, loss caused by leakage of a large amount of oil liquid for a gas station is avoided, and meanwhile serious pollution caused to underground water is avoided.

Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-well hole, 2-water filtering layer, 3-pipeline, 30-water through hole, 4-filtering layer, 5-bearing platform, 6-well cover and 7-clay sealing layer.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in figure 1, the utility model discloses an observation well for oil tank oil leakage observation and sewage collection, including wellhole 1 and pipeline 3, pipeline 3 is located wellhole 1, and the one end of pipeline 3 extends to the wellhole 1 outside, it has water filtering layer 2 to fill between pipeline 3 lateral wall and the wellhole 1 lateral wall, the part processing that is close to the wellhole 1 hole bottom on the pipeline 3 has a plurality of water holes 30 of crossing, the drill way of wellhole 1 is located and is built cushion cap 5 on water filtering layer 2, and pipeline 3 is located the inboard of cushion cap 5.
The water filtering layer 2 is formed by gravel packing.
The particle size of the gravel is 10-30 mm.
The conduit 3 is arranged coaxially with the wellbore 1.
The unilateral clearance between the pipeline 3 and the well hole 1 is 150 mm-250 mm.
And a filter layer 4 is arranged between the pipeline 3 and the water filtering layer 2.
The filter layer 4 is made of geotextile or a stainless steel wire mesh. When the filter is used, the outer wall of the pipeline 3 is wrapped with a layer of geotextile, or a stainless steel wire mesh is paved, so that the filter layer 4 is used for further filtering, and fine sand and large particle impurities are prevented from entering the pipeline 3.
The pipeline 3 is made of hot-dip galvanized steel pipes, and 2 layers of epoxy asphalt paint are coated on the inner wall of the pipeline 3.
The inner walls of the water through holes 30 are coated with a zinc-rich primer 2 layer.
The well lid 6 that is used for sealed pipeline 3 upper end is installed to cushion cap 5's inboard, and the outside at 2 tops of drainage layer is equipped with clay closed layer 7, and the inner wall of clay closed layer 7 and the outer wall connection of cushion cap 5.
