With reference to figure 1, it can be equipped with filtration and infiltration layer 14 in the bottom in antiseepage oil tank pond 10, filled layer 13 is set to filtration and infiltration 14 top of layer, when leaking, filtration and infiltration layer 14 can play the role of isolation filtering, prevent the part material of filled layer 13 Stream enters to hunt leak the opening of standpipe 20, and filtration and infiltration layer 14 can select cobble, a diameter of 10mm-30mm of cobble, in this way Filtering and osmotic effect are good, and material is cheap.
As shown in Figure 1, the end of the bottom surface in antiseepage oil tank pond 10 is equipped with the oil sump 15 to lower recess, antiseepage oil tank pond 10 Bottom surface tilted gradually downward from centre to oil sump 15, the gradient of the bottom surface in antiseepage oil tank pond 10 is 0.8%-1.5%, such as 1%, the water of leakage or the oil of leakage can import oil sump 15 along the bottom surface in antiseepage oil tank pond 10, and filling is not set in oil sump 15 Oil sump 15 is stretched into the lower end of object, leak detection standpipe 20, convenient for extracting.
With reference to figure 1 and Fig. 2, the upper surface of oil sump 15 is covered with isolation board 16, and isolation board 16 is set in leak detection standpipe Outside 20, and isolation board 16 is equipped with multiple weepage holes 17, and isolation board 16 is used to prevent the filtration and infiltration layer 14 of top from falling to oil-collecting Pond 15, weepage holes 17 can be multiple and be formed as dot matrix type, and the diameters of weepage holes 17 can be 5mm-10mm, such as 8mm, this For sample when selecting material of the cobble for filtration and infiltration layer 14, cobble does not pass through weepage holes 17.Isolation board 16 can be steel plate, than Such as the steel plate of 20mm thickness, the side of isolation board 16 is welded with the side in antiseepage oil tank pond 10, and the other side can be supported on seepage-proof oil On the step that the bottom surface in tank pond 10 is formed.
Standpipe 20 of hunting leak can be multiple, for example leak detection standpipe 20 can be two, accordingly, the bottom in antiseepage oil tank pond 10 The both ends in face are respectively equipped with the oil sump 15 to lower recess, and two leak detection standpipes 20 are inserted into oil sump 15 respectively.
As shown in Figure 1, leak detection standpipe 20, which is embedded at least partly wall surface in antiseepage oil tank pond 10, is equipped with through-hole 21, infiltration Oil and level can penetrate through-hole 21 and enter leak detection standpipe 20, and through-hole 21 is multiple, and is distributed as dot matrix type upwards from lower end, is examined Leak standpipe 20 close to bottom surface one section can not set through-hole 21, and the diameter of through-hole 21 can be 5mm-10mm, such as 8mm.
At least partly wall surface that leak detection standpipe 20 is externally provided with through-hole 21 is coated with separation layer 11, such as leak detection 20 peripheral hardware of standpipe One section of the outside that oil sump 15 is not extended into the wall surface for having through-hole 21 is coated with separation layer 11, and separation layer 11 is for preventing from filling out The sand for filling layer 13 blocks through-hole 21, and separation layer 11 can select cobble, a diameter of 10mm-30mm of cobble, this spline filter and Osmotic effect is good, and material is cheap, and the separation layer 11 of cobble material can be limited by fixed net 12, to prevent cobble from falling to In sand, fixed net 12 can be wire netting.
The top of leak detection standpipe 20 is equipped with rain cover 22, for preventing rainwater from entering antiseepage oil tank pond by standpipe 20 of hunting leak 10, the height that the upper end of leak detection standpipe 20 elevates above the soil, and is above the ground level can be 200mm or more, such as 300mm, in this way may be used To prevent excess surface water from flowing into, rain cover 22 can removably be connected by the upper end that junction block elevates above the soil with leak detection standpipe 20 It connects, when needing to draw water or pump, disassembles rain cover 22.
Antiseepage oil tank pond 10 is additionally provided with inspection-pit 31, and inspection-pit 31 can be concrete construction, be covered on inspection-pit 31 Rain-proof cover 32.
It should be noted that the seepage control system 100 of the utility model embodiment accomplishes system-wide closure, in order to prevent Into the scene in antiseepage oil tank pond 10, the disclosure has all been done corresponding anti-in the place for being possible to water inlet for the roof leaking being likely to occur Shield measure ensure that rainwater will not enter to greatest extent.
In some embodiments, seepage control system 100 further includes:Control system and alarm.Control system and sensor electricity Connection, and sends out alarm when sensor detects sepage, control system can be middle console, and can be according to detecting It is that oil or water show different signals, and indicate the antiseepage oil tank pond 10 of specific oil leak.Alarm is installed on antiseepage oil tank pond At 10, and alarm is electrically connected with sensor, and alarm is sent out when sensor detects sepage, and alarm for reporting on the spot It is alert.
Using certain MSW Incineration Plant as research object, in the related technology, oil tank region the considerations of without system Seepage control measure only requires to have carried out concrete anti-seepage pond according to environmental impact assessment, in antiseepage when environmental impact assessment requires oil tank region to carry out antiseepage Sand is filled out in pond, after rainy season set, ponding is excessive in oil tank pond and does not have drainage measure, leads to the pipe deforming of conveying oil, no It is able to rearrange after taking out oil tank pool area whole pipeline with equipment.
After the seepage control system 100 of the utility model embodiment, environmental impact assessment can be successfully passed and put down in follow-up operation , there is not seeping phenomenon in steady operation, once diesel oil leakage occurs, can also find simultaneously timely processing at the first time.
In conclusion 100 component of seepage control system according to the utility model embodiment is simple, technique is advanced, enforcement difficulty Low, material, pipeline and sensor used is ordinary articles in engineering, and purchase cost is low, easy for construction.And by with middle control Room is electrically connected, and the level of informatization is high, can effectively be examined by stringent environmental impact assessment.
