Abstract
The invention relates to a trench and sewage tank connecting structure, in particular to a trench and sewage tank anticorrosion connecting structure which is suitable for aluminum oxide plants and can resist alkali corrosion. The trench and sewage tank anticorrosion connecting structure comprises a sewage tank pit and an alkali-resisting trench. A steel plate rectangular connecting pipe is arranged at a position at which the sewage tank pit is connected with the alkali-resisting trench. A steel plate casing is sheathed outside the steel plate rectangular connecting pipe. The steel plate casing is fixed in the sewage tank pit through flat steel. A sewage tank is arranged in the sewage tank pit. The steel plate rectangular connecting pipe is inserted into the wall of the sewage tank. A steel plate flashing sheet is arranged above the steel plate casing. Alkali-resisting cement is used for the plugging between the steel plate casing and the alkali-resisting trench and between the alkali-resisting trench and the sewage tank pit. The trench and sewage tank anticorrosion connecting structure has the advantages that the tightness is good, the structure is rainproof, the service life is long, and not only can the problem of settlement between two structures be effectively solved, but also the leakage of alkali liquid is effectively prevented and the durability is good.
Description
Technical field
The present invention relates to a kind of trench and sump syndeton, the trench that particularly relates to a kind of applicable alumina producer alkali corrosion resistance is connected anticorrosion structure with sump.
Background technology
In alumina producer manufacturing process, produce a large amount of alkali lye and flow into sump through trench.The deformation process of common trench and sump junction and the sealing of limit, hole can not meet anti-caustic corrosion requirement, in long-term use, alkali lye can infiltrate in reinforced concrete beam, basis and basic soil along seam, make reinforced concrete beam, basis destroyed by crystallographic expansion, impact is produced, impair one's health, and soil is polluted.
Summary of the invention
To the invention provides a kind of trench and be connected anticorrosion structure with sump in order to solve the problems of the technologies described above; it has solved sump melt pit and trench is subject to caustic corrosion crystallographic expansion to destroy problem; object is to prevent that concrete beam, basis are destroyed by alkali lye penetrant crystalline; improve application life, ensure to produce normal operation protection of the environment.
Be connected anticorrosion structure for reaching above-mentioned purpose trench of the present invention with sump, comprise sump melt pit and alkaline-resisting trench, be provided with steel plate rectangular tube at sump melt pit and alkaline-resisting trench junction, steel plate rectangular tube overcoat has steel casing, steel casing is fixed in sump melt pit by band steel, in sump melt pit, be provided with sump, steel plate rectangular tube is inserted in sewage cell wall, the top of steel casing is provided with steel plate flashing sheet, stifled by alkali-resistant glue mudding between steel casing and alkaline-resisting trench, alkaline-resisting trench and sump melt pit.
One end of described steel plate flashing sheet and the welding of sewage cell wall, the other end of steel plate flashing sheet is bending downwards above steel casing.
Described steel plate flashing sheet exceeds the high 200 ~ 500mm of alkaline-resisting trench top mark.
Described steel casing stretches into alkaline-resisting trench 200 ~ 400mm.
Described steel plate rectangular tube puts in sewage cell wall 30 ~ 100mm, steel plate rectangular tube and the welding of sewage cell wall.
Described steel plate rectangular tube bottom surface absolute altitude is lower than alkaline-resisting ground bottom of trench absolute altitude 15 ~ 50mm.
Described steel casing and the welding of steel plate rectangular tube.
Advantageous effect of the present invention:
Steel plate rectangular tube of the present invention and the welding of sewage cell wall are tight, and steel casing stretches into alkaline-resisting trench and welds with steel plate rectangular tube, and steel casing is fixed on sump melt pit by band steel, on steel casing, establish steel plate flashing sheet, leakproofness is good, rainproof, long service life.Stifled by alkali-resistant glue mudding between steel casing and alkaline-resisting trench, alkaline-resisting trench and sump trench, both efficiently solved the settlement issues between two structures, and effectively prevented alkali lye seepage and have good durability.
