Abstract
The utility model relates to a kind of sewage treatment plant's biochemistry pool float Structures.The purpose of the utility model is to provide a kind of simple, practical and economic sewage treatment plant's biochemistry pool float Structures.The technical solution of the utility model is: a kind of sewage treatment plant's biochemistry pool float Structure, it is characterized by: being successively backfilled with graded broken stone and excavated material on the outside of the concrete-pool-wall of biochemistry pool, it is successively arranged argillic horizon at the top of the graded broken stone and excavated material and ploughs and plants soil layer, ploughs and plants green grass on soil layer；The pre-buried PVC perforated drain pipe in graded broken stone bottom, is equipped with non-woven geotextile between the graded broken stone and excavated material and argillic horizon.The utility model is suitable for sewage treatment plant's biochemistry pool.
Description
Technical field
The utility model relates to a kind of sewage treatment plant's biochemistry pool float Structures.Suitable for sewage treatment plant's biochemistry pool.
Background technique
The biochemistry pool of sewage treatment plant is generally concrete structure, and side and bottom plate are enclosed construction, and embedment underground is certain
Depth, measurement for biochemical pool wall and bottom plate bear outer lateral earth pressure and groundwater pressure effect.
It is anhydrous inside pond during maintenance in biochemistry pool construction period and after building up, when rainy season or level of ground water compared with
Gao Shi, pond will receive larger underground water buoyancy, be easy to appear floating or deformation failure.It is anti-in order to meet concrete structure
Floating to require, generally using self weight anti-floating is increased when design, substrate counterweight anti-floating plays the methods of uplift pile or anchor pole anti-floating.These
Engineering measure requires to increase the project amount of biochemistry pool, the especially higher area of level of ground water, considerably increases difficulty of construction
And project cost.
Summary of the invention
Technical problem to be solved by the utility model is: in view of the above problems, providing a kind of simple, practical and warp
Sewage treatment plant's biochemistry pool float Structure of Ji.
The technical scheme adopted by the utility model is a kind of sewage treatment plant's biochemistry pool float Structure, it is characterised in that:
Successively be backfilled with graded broken stone and excavated material on the outside of the concrete-pool-wall of biochemistry pool, at the top of the graded broken stone and excavated material according to
It is secondary to be equipped with argillic horizon and plough plant soil layer, it ploughs and plants green grass on soil layer；The pre-buried PVC perforated drain pipe in graded broken stone bottom,
Non-woven geotextile is equipped between the graded broken stone and excavated material and argillic horizon.
The grain composition of the graded broken stone meets following table requirement:
Width W >=1.5m of the graded broken stone.
The thickness of clay soil is 30cm.
The cultivated plant soil thickness is 10cm, the gradient draining of surface setting 3%.
The PVC perforated drain pipe diameter is 300mm, and infiltration is collected by PVC perforated drain pipe, is connected to subsoil drain
Road discharge.
The beneficial effects of the utility model are: the utility model one circle gradation of setting on the outside of the concrete-pool-wall of biochemistry pool
Rubble, and drained by the PVC perforated drain pipe of graded broken stone bottom, avoid biochemistry pool because floating by biggish underground water
Power effect occurs floating or deformation failure.The utility model structure is simple, easy for construction, cost is relatively low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment.
Specific embodiment
As shown in Figure 1, the present embodiment is a kind of sewage treatment plant's biochemistry pool float Structure, in the concrete-pool-wall of biochemistry pool
1 outside is backfilled with the graded broken stone 2 that a circle surrounds biochemistry pool, 2 width W >=1.5m of graded broken stone.2 bottom preset of graded broken stone is straight
Diameter is the PVC perforated drain pipe 3 of 300mm, which surrounds biochemistry pool one week, and the underground with sewage treatment plant
Drainage pipeline is connected, and infiltration is collected by PVC perforated drain pipe 3, is discharged by underdrainage system.
In order to preferably realize permeable effect, graded broken stone 2 should be cleaned up, and grain composition need to meet following table requirement:
Backfill macadam gradating table
Excavated material is backfilled in the present embodiment on the outside of graded broken stone 2, and the clay particle infiltration in excavated material in order to prevent
Drainage effect is influenced in the gap of graded broken stone 2, non-woven geotextile 5 is set between excavated material 4 and graded broken stone 2.
It successively sets backfill in graded broken stone 2 and 4 top of excavated material in this example and is formed with argillic horizon 6 and ploughs and plant soil layer 7, wherein
6 thickness 30cm of argillic horizon；It ploughs and plants 7 thickness 10cm of soil layer, plough the gradient draining for planting 7 surface of soil layer setting 3%, and plant in soil layer 7 ploughing
Green grass reduces rainwater infiltration capacity.Infiltration lane is blocked to prevent 6 particle of upper layer argillic horizon from penetrating into graded broken stone, in grade
With one layer of horizontal non-woven geotextile 5 of setting between rubble 2 and argillic horizon 6.
Certainly, above description is not limitation of the utility model, and the utility model is also not limited to the example above, this skill
The those of ordinary skill in art field, in the scope of the utility model, variation, addition or the replacement made all should belong to this reality
With novel protection scope.
