Description
Technical field
It is more specifically a kind of raw with precast concrete block the utility model relates to arrive Water Ecological Recovery technical field
The sewage ditch of state slope protection.
Background technique
In recent years, " water pollution " becomes the very high vocabulary of frequency of use.Since water crisis frequency caused by polluting is existing, various regions water
Pollution Crisis is constantly broken out, this is not accidental unexpected incidents, it shows that the development pattern of Traditional Industrialization not only makes China
Resource environment to the baseline for being difficult to bear, also seriously threaten the daily life of the people.
Currently, existing conventional drainage major function, which only meets from sewage quantity, blowdown speed etc. merely, arranges
Dirt requires, and in order to make drainage while be also equipped with the functions such as removal pollution of area source, sewage self-cleanse, can pass through corresponding engineering measure
With botanical system building construction at subtracting dirty and pollution discharge type sewage ditch.Certain engineering measure and sewage purification work are used in sewage ditch
Skill effectively can stablize purpose by reinforcing side slope；And it is planted in the aquatic plant system in sewage ditch, there is barrier exogenous nutrition, inhale
The function of receiving water body nitrogen phosphorus, beautify blowdown irrigation canals and ditches, rhizome can also inhibit the release of nutrients in sludge, plant growth later period
Unified harvesting removal can also be facilitated.But existing sewage ditch mostly uses concrete, stone masonry, cement brick etc. protective slope structures,
Structure is single, cost is high, landscape effect is poor, does not meet environmental friendly principle also；And it is steady using the sewage ditch side slope of botanical system merely
It is qualitative it is poor, anti-seepage effect is poor, and be easy to cause soil erosion, collapse the problems such as.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of above-mentioned background technology, and propose a kind of with concrete
The sewage ditch of soil block ecological slope protection.
The purpose of this utility model is implemented by following technical solution: one kind is protected with precast concrete block ecology
The sewage ditch on slope, it includes the side slope positioned at the basis of bottom and positioned at the basis left and right sides；The basis is by upper
Cobblestone bed course, concrete cushion and blotter are equipped under；If dislocation stacking has along longitudinal direction respectively in the side slope
Dry precast concrete block and transversely stacking have several precast concrete blocks of three rows, use cement between the precast concrete block
Mortar is built, and aquatic plant system is equipped in each precast concrete block, in each precast concrete
Building stones, sandy soil and planting soil are filled in block, each precast concrete block is provided with anti-with the side slope contact surface
Seep geotextiles；The cobblestone bed course is horizontally arranged with able to turn on or off between the side slope of two sides in the basic tail portion
Gate.
In the above-mentioned technical solutions: the gradient of the side slope is between 1:0.6-1:1.
In the above-mentioned technical solutions: the cobblestone bed course with a thickness of 10-20 centimetres, cobble partial size existsThe concrete cushion is with a thickness of 20 centimetres, and the blotter is with a thickness of 20 centimetres
In the above-mentioned technical solutions: the horizontal spacing between precast concrete block described in adjacent two rows is 15-20 lis
Rice, each precast concrete block is having a size of 60 centimetres * 30 centimetres * 30 centimetres；Each precast concrete block is met
The water surface and bottom are provided with the hole of same size.
The utility model, which has the advantages that, uses precast concrete block and plant in 1. the utility model sewage ditch side slopes
System carries out ecological slope protection processing, not only prevents ditch slope from collapsing, soil erosion, can also pass through precast concrete block and botanical system
Delay water volume flow rate in ditch, increases sewage hydraulic detention time, be more advantageous to the removal of nitrogen phosphorus in pollutant.
2, the utility model sewage ditch is of simple structure and low cost, building is convenient, by directly building in sewage ditch side slope
Precast concrete block plays the role of firm side slope, while also delaying water volume flow rate, and the aquatic plant system in side slope is enable to fill
Divide the nitrogen and phosphorus pollution object in resolution water body, moreover it is possible to the effect for playing the role of beautification of landscape, making sewage ditch is not only blowdown, and
And still landscape belt.
3, the aquatic plant system of the utility model sewage ditch has selected easy to maintain, fast growing to have both landscape planting
Industrial crops not only eliminate the trouble of daily maintenance, also bring certain economic benefit by regularly gathering in every year.
