The bar hole that bolt passes on the transformer pad pin is fixedly mounted on transformer on the transformer pad pin; When rainwater infiltrates the collecting-tank the prefabricated melt pit basis from the top cover slit in; When water level arrives the liquid level setting height, can extract the water in the collecting-tank out prefabricated melt pit basis through starting dredge pump automatically; The grounding base installing hole of being opened on the sidewall can be guaranteed the transformer and prefabricated melt pit basis body and the earth formation reliable ground that are installed in the prefabricated melt pit basis safe in utilization.
Wherein, Said sidewall (2) is the rectangular cavity that is surrounded by four concavo-convex steel plate welding, and said concavo-convex steel plate is by the steel plate punch forming of thickness of slab greater than 6mm, and the junction of adjacent two concavo-convex steel plates is welded with support bar (6); The below of the top of said sidewall (2), diapire (1) all is welded with rectangular frame (7); Adopt concavo-convex steel plate punch forming, both guaranteed the mechanical strength on prefabricated melt pit basis, practiced thrift cost again.
The middle part of said sidewall (2) is welded with upper and lower twice and strengthens angle steel (8) along sidewall (2) inboard; The below of said diapire (1) is welded with strengthens channel-section steel (9); Said reinforcement channel-section steel (9) and the height such as said rectangular frame (7) grade that is welded on diapire (1) below; And strengthen channel-section steel (9) and be positioned at this rectangular frame (7); Further to guarantee the mechanical strength on prefabricated melt pit basis, suffered extruding force is out of shape when preventing prefabricated melt pit basis earth on every side because of sinking.
The top of said sidewall (1) is welded with to hang mixes (10), can prefabricated melt pit basis installed or taken out by crane.
Prefabricated melt pit basis has following characteristics: 1, the melt pit basis can be adopted greater than 6mm steel plate pre-molding; All-sealed structure; Guarantee that surface water and other foreign material can not get in the melt pit; Also can adopt the prefabricated reinforced concrete structure, adopt advanced waterproof technique to handle, guarantee that the basis is non-leakage.
2, the melt pit bottom is provided with collecting-tank, and the submersible pump that receives automatic drain system control is installed.
In sum, the utility model fully takes into account integral body and has good waterproof, drain function and safety measure in design; It is simple in structure, mechanical strength is high, pick and place conveniently, cost is low, has solved the problem that traditional box type transformer takies surface area, is unfavorable for landscaping, noise is big, has vast market prospect.

Fig. 3 is the vertical view of Fig. 1.
Fig. 4 is the structural representation of concavo-convex steel plate.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Prefabricated melt pit basis like Fig. 1, Fig. 2, underground transformer shown in Figure 3 is made up of diapire 1, sidewall 2, transformer pad pin 3, collecting-tank 4 and ground hole 5 etc.Diapire 1 is a steel plate, and sidewall 2 is the rectangular cavity that surrounded by four concavo-convex steel plates welding, and both are integrally welded for diapire 1, sidewall 2.The junction of adjacent two concavo-convex steel plates is welded with 6, four support bars of support bar 6 and height such as concavo-convex steel plate grade, and support bar 6 is processed by quarter bend.The below of the top of sidewall 2, diapire 1 all is welded with rectangular frame 7, and the length of rectangular frame 7, width dimensions equate that with length, the width dimensions of rectangular cavity rectangular frame 7 is to be welded by channel-section steel.Have grounding base installing hole 5 on the sidewall 2.
As shown in Figure 3, be welded with two transformer pad pin 3 on the diapire 1, transformer pad pin 3 is a channel-section steel, two transformer pad pin 3 are parallel, have bar hole 31 on the transformer pad pin 3, are used to install transformer.
In conjunction with Fig. 2, Fig. 3,, the upper edge that diapire 1 is provided with collecting-tank 4 and collecting-tank 4 flushes with diapire 1, and collecting-tank 4 is welded by steel plate, and collecting-tank 4 is welded on the diapire 1.
In conjunction with Fig. 1, Fig. 2; The middle part of sidewall 2 is welded with upper and lower twice and strengthens angle steel 8 along sidewall 2 inboards; The below of diapire 1 is welded with strengthens channel-section steel 9, strengthen channel-section steel 9 and rectangular frame 7 height such as grade that are welded on diapire 1 below, and reinforcement channel-section steel 9 is positioned at this rectangular frame 7.
The cross sectional shape of concavo-convex steel plate is as shown in Figure 4, and concavo-convex steel plate is by the steel plate punch forming of plate thickness greater than 6mm, and the concavo-convex steel plate of same thickness has better mechanical strength than flat board.
As preferably, like Fig. 1, Fig. 2, the top of sidewall 1 is welded with to hang mixes 10, and outer Thursday of the angle of sidewall is distributed with a plurality of hanging and mixes 10, hangs and mixes 10 vertically settings.Prefabricated melt pit basis upper edge has the holder 11 of a plurality of immobilizing foundation top covers, flushes with prefabricated melt pit basis upper edge.
Certainly, the rectangular cavity that constitutes sidewall is not necessarily selected concavo-convex steel plate for use, also can directly adopt flat board to be welded, and just dull and stereotyped thickness will increase.The support bar of the junction welding of adjacent two concavo-convex steel plates; The top of sidewall, the below of diapire all are welded with rectangular frame; The middle part of sidewall is welded with upper and lower twice along inside sidewalls and strengthens angle steel; And the reinforcement channel-section steel of the below of diapire welding, all be in order to guarantee overall mechanical strength, can be provided with as required.
This utility model integral solder forms, and all weld seams detect through defect-detecting equipment the seepage phenomenon can not occur, and its mechanical strength should guarantee to can't harm injure in the use after transformer is installed unallowed permanent deformation to occur; Pickling, phosphatization are answered in the inside and outside surface of body, hole, surfaces coated anti-corrosion material twice, and assurance prefabricated melt pit basis can be moved under the adverse circumstances of underground humidity more than 20 years; External surface sprays the black amino baking enamel on prefabricated melt pit basis at last.Also can adopt the prefabricated reinforced concrete structure, adopt advanced waterproof technique to handle, guarantee that the basis is non-leakage.
