Description
Technical field
The utility model relates to a kind of leakage preventing structure, especially relates to a kind of leakage preventing structure being applied to petroleum chemical industry sewage reservoir.
Background technology
In recent years, the pollutant that petrochemical industry is caused by a variety of causes is revealed and is caused circumferentially descending water environment pollution, causes serious threat to Environmental security.Because sewage reservoir all kinds of in Petrochemical Projects has larger pollution risk to periphery underground water, and after groundwater pollution difficulty of governance large, time long, costly.So particularly important to the Anti-seeping technology of sewage reservoir all kinds of in Petrochemical Projects.
When in the dark scope in pond, pond without underground water and Site soil is better time, traditional method adopts impervious steel reinforced concrete pool wallboard and base plate, sometimes also needs brushing anticorrosive paint.Chinese patent CN101979781A discloses method for constructing oil drilling waste mud solidification pool, relate to oil and gas exploration drilling well pollutant abatement technology field, its scheme is: digging in-situ solidification pond, pool wall gradient is 45 °-60 °, pond height 2.0-2.5m, clay-non-woven geotextile-high-density polyethylene geomembrane-non-woven geotextile is adopted to carry out antiseepage at the bottom of pond, non-woven geotextile-high-density polyethylene geomembrane-non-woven geotextile is wrapped up solid waste to top always, and top C20 concrete capping is to ensure that firming body does not exosmose.Solidify pond object described in this patent and be that discarded slurry being closed curing disposable uses, petrochemical enterprise repeatedly collects rear unified process demand to oil-polluted water can not be met.The utility model is used for carrying out after-treatment to it after sewage temporarily stores, and can repeatedly utilize.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of leakage preventing structure being applied to petroleum chemical industry sewage reservoir is provided, protection groundwater environment.
The purpose of this utility model can be achieved through the following technical solutions:
Be applied to a leakage preventing structure for petroleum chemical industry sewage reservoir, on the bottom surface being arranged on sewage reservoir and sidewall, this leakage preventing structure from being followed successively by outer concrete plate, polypropylene chopped fiber non-woven fabrics, inner impervious barrier and compacting soil layer outside to inside,
Described outer concrete plate is cement sand plaster, concrete precast block, cement mortar screeding layer from setting gradually outside to inside,
Described inside impervious barrier is from the main antiseepage film of HDPE set gradually outside to inside, composite earthwork drainage network, HDPE antiseepage film, GCL GCL.
Preferably, concrete precast block adopts C30 concrete.
Preferably, the main antiseepage film of HDPE and the HDPE antiseepage film that are applied in sewage reservoir sidewall are two exasperate structure, and the main antiseepage film of HDPE and the HDPE antiseepage film that are applied in sewage reservoir bottom surface are two light faces structure.
Preferably, polypropylene chopped fiber non-woven fabrics is the separation layer between outer concrete plate and inner impervious barrier.
Preferably, the coefficient of consolidation of compacting soil layer is not less than 0.94.
Traditional sewage reservoir way is reinforced concrete structure, construction needs carry out excavating, colligation, formwork, build, the multiple working procedure such as backfill, construction period is longer and cost is higher.Compared with conventional art, the utility model just can lay leakage preventing structure after only carrying out excavation compacting, have that structure is simple, easy construction, advantage that cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is cement sand plaster, and 2 is concrete precast block, 3 be cement mortar screeding layer, 4 for polypropylene chopped fiber non-woven fabrics, 5 be the main antiseepage film of HDPE, and 6 is composite earthwork drainage network, and 7 is HDPE antiseepage film, and 8 is GCL GCL, and 9 is compacting soil layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
A kind of leakage preventing structure being applied to petroleum chemical industry sewage reservoir, on the bottom surface being arranged on sewage reservoir and sidewall, its structure as shown in Figure 1, this leakage preventing structure is from being followed successively by outer concrete plate, polypropylene chopped fiber non-woven fabrics 4, inner impervious barrier and compacting soil layer 9 outside to inside, wherein, outer concrete plate is cement sand plaster 1, concrete precast block 2, cement mortar screeding layer 3 from setting gradually outside to inside, and inner impervious barrier is from the main antiseepage film 5 of HDPE set gradually outside to inside, composite earthwork drainage network 6, HDPE antiseepage film 7, GCL GCL 8.The polypropylene chopped fiber non-woven fabrics 4 arranged between outer concrete plate and inner impervious barrier uses as separation layer, thus can the impervious barrier structure of available protecting internal layer, and the effect of leak detection can also be played in composite earthwork drainage network 6.Concrete precast block 2 adopts C30 concrete for making to obtain, and the coefficient of consolidation of compacting soil layer 9 is not less than 0.94.It should be noted that, because sewage reservoir sidewall has certain slope, in order to increase the frictional force of antiseepage film so that construction, the main antiseepage film 5 of HDPE and the HDPE antiseepage film 7 that are applied in sewage reservoir sidewall are two exasperate structure, and the main antiseepage film 5 of HDPE and the HDPE antiseepage film 7 that are applied in sewage reservoir bottom surface can adopt two light faces structure.
When constructing the utility model; Site Soil puts slope, fill and lead up compacting after; first GCL GCL 8 is laid; GCL can available protecting upper strata impervious material and have perforation self-healing ability feature; namely be expanded into colloid after bentonite clay particle water suction, can bond voluntarily under pressure condition in perforation place.Then lay HDPE antiseepage film 7 as auxiliary seepage proof layer, pool wall adopts two exasperate film, adopts two light facial mask at the bottom of pond.Secondly composite earthwork drainage network 6 is laid as layer of mainly hunting leak, basin bottom should arrange more than the 1% water guide gradient, and as upper strata antiseepage film because unexpected factor is damaged, sewage can in drainage network along the following current of the water guide gradient, arrange collection well in minimum point, namely whether the main antiseepage film of Observable has breakage.Re-lay the main antiseepage film of HDPE 5 as main impervious barrier, pool wall adopts two exasperate film, adopts two light facial mask at the bottom of pond.Lay polypropylene chopped fiber non-woven fabrics 4 subsequently as the separation layer between upper strata concrete slab and impervious barrier, protection lower floor antiseepage film.After carrying out cement mortar screeding, adopt 1: 3 cement mortar joint filling pave concrete precast block and carry out secondary cement sand plaster on its surface.
