Abstract
The utility model relates to a simple, practical and effective closure structure of a sludge house. By adopting the closure structure, the construction problems such as high water content ratio and low shearing strength of sludge can be solved in the case of closure cover of the sludge house, rainwater can be effectively isolated from sludge water, and personnel health and ambient environment are not affected during the implementation process of the closure structure. The closure structure of the sludge house is characterized by comprising a reinforcement layer, an air exhaust layer, an anti-seepage layer, a drainage layer and a vegetation layer which are sequentially arranged from bottom to top and are closely attached to the upper part of the sludge layer in the sludge house. The closure structure of the sludge house is applicable to closure cover of the sludge house with high water content and low shearing strength and is also suitable for reinforcement of a soft foundation with extremely low bearing capacity such as silt and the like.
Description
Technical field
The utility model relates to a kind of mud storehouse closing structure, is applicable to that the closing in the mud storehouse of high-moisture, low shear strength covers, and also is applicable to the reinforcing of the soft foundation of extremely low bearing capacity such as mud.
Background technology
For refuse landfill domestic existing comparatively the closing covering system and the implementation method of standard, but for moisture content far above rubbish, substantially do not have bearing capacity, can not moulding the closing in mud storehouse cover, still lack design and embodiment reliably at present.Main cause is that moisture percentage in sewage sludge is high, shear strength is extremely low, and the surface also has darker sewage mixture to be difficult to separate, can't to satisfy the required requirement for bearing capacity of construction closing structure.And extensively apply to foundation reinforcement method on Pond Silt or the seabeach mud, as mixing with soil, slip casting, chemical consolidation, vacuum or precompressed plate discharging consolidation etc., because of hazardous substances in the mud and organic content height, mix to stir and influence constructor's health and surrounding environment, discharging consolidation are difficult to gather effect because of the thin content of organics height of mud granule.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of simple, practical, effective mud storehouse closing structure is provided, can solve moisture percentage in sewage sludge height when the mud storehouse close covered, construction difficult problem that shear strength is low, can effectively isolate rainwater and sludge water, and this structure can not influence personnel health and surrounding environment when implementing.
The technical scheme that the utility model adopted is: a kind of mud storehouse closing structure is characterized in that: it comprises the top of being close to sludge blanket in the mud storehouse, the back-up coat that from bottom to top sets gradually, exhaust level, impervious barrier, drainage blanket and vegetable layer.
Described back-up coat is the polystyrene foam plate that overlaps mutually.
Described exhaust level comprises the composite drainage network of horizontal arrangement and the stack of vertically arranging, described stack lower end is goed deep in the described composite drainage network, stretch out outside the described closing structure upper end.
Described impervious barrier comprises high-density polyethylene geomembrane or linear low density of polyethylene geomembrane tiling, that be anchored in storehouse week, is close to these geomembrane tow sides and all is lined with geotextiles.
The composite drainage network that described drainage blanket is arranged horizontally.
Described vegetable layer is the clay that thickness is not less than 40cm, and the middle part of described clay is higher than periphery, and its gradient is 2%.
The beneficial effects of the utility model are: the utility model from bottom to top sets gradually back-up coat, exhaust level, impervious barrier, drainage blanket and vegetable layer on sludge blanket top, in mud can being enclosed in by these five decks, isolated surperficial rainwater, rainwater and sludge water are taken their own roads in that impervious barrier is upper and lower, discharge outside the storehouse respectively and handle by separately draining, exhaust level; And this structure is when implementing, and need not can not influence constructor's health and surrounding environment to mud mixing stirring, for similar engineering from now on provides successful technical experience.
Description of drawings
Fig. 1 is the sectional view of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the mud nature consolidation time in some mud storehouse is very long, and decades-long exists pollution and safety problem to environment.For this reason, present embodiment from bottom to top sets gradually back-up coat 2, exhaust level 3, impervious barrier 4, drainage blanket 5 and vegetable layer 6 on the top of sludge blanket 1, constitutes mud described in the utility model storehouse closing structure.In the present embodiment, the concrete structure of above-mentioned five decks is as follows:
Back-up coat be laid on the sludge blanket 1, density 20kg/m
3, compressive strength 100kPa polystyrene foam plate (being the EPS plate), its thickness is determined by last overburden layer load and construction equipment load, therefore exhaust level 3, impervious barrier 4 and the drainage blanket 5 on it all adopts the geosynthetics material of lightweight to reduce the thickness of EPS plate, the reduction cost.The EPS plate has light weight, water imbibition is little and the characteristics of high-mechanical property, can adapt to the distortion of mud, the bearing capacity of raising mud, during enforcement, every block of plate overlaps mutually, with the homogenizing working load and keep the stability of EPS plate, thereby satisfy the requirement of the construction of top exhaust level 3, impervious barrier 4, drainage blanket 5 and vegetable layer 6 and the geomembrane in load bearing requirements and the following impervious barrier to the mud deflection.
The main part of impervious barrier 4 is the high-density polyethylene geomembrane (being the HDPE geomembrane) or the linear low density of polyethylene geomembrane (being the LLDPE geomembrane) of tiling, and the tow sides of this geomembrane (upper and lower surfaces) all are lined with geotextiles, to protect this geomembrane.Described geomembrane need be anchored at around the mud storehouse, can adopt the excavation anchor slot, fixes with concrete or clay backfilling again, to prevent surperficial rainwater infiltration, rainwater and sludge water is taken their own roads in that impervious barrier is upper and lower.
The material of drainage blanket 5 is for directly being layered on the composite drainage network on the impervious barrier 4; also be the geonet discharge structure that comprises geotextiles draining filtering layer of porous, high water-permeability, it can make rainwater discharge rapidly and protect the geomembrane in the impervious barrier not to be subjected to infringements such as root system of plant, ultraviolet ray.
The soil layer of vegetable layer 6 is a clay.During enforcement, soil thickness generally is not less than 40cm, to keep the growth of natural vegetation.And 2% the gradient (middle high, periphery is low) is made on the soil layer surface, is beneficial to rainwater and arranges to periphery as early as possible and cut Great Gulch.
