Abstract
The utility model relate to a kind of saline-alkali soil greening construction every alkali, row's alkali system.Because the greening construction in a lot of saline land, coastal cities is every alkali, row's alkali measure is not in place, causes the salt-alkali contaminated very soon of the planting technique of replacing, causes the bad or large stretch of death of seedling growth.The utility model comprises drainage pipeline system, it is characterized in that described drainage pipeline system comprises many arms, described arm is connected to supervisor, described supervisor is connected to gully, gully external connection row supply mains is connected to city planting ductwork, described supervisor, arm and main sewer are all buried underground in channels, and described arm and supervisor are the blind pipe having through hole on its surface, fill medium coarse sand in described raceway groove.The utility model flow to house steward or draining alkaline discharging well by arm, be disposed to city planting ductwork again, avoid planting soil to pollute by saline-alkali water, the Heat resources Polypropylence Sheet of limit, greenery patches and saline-alkali soil or geomembrane Polypropylence Sheet are laid and can be completely cut off outer peripheral salt-alkali contaminated, thus guarantee nursery stock energy normal growth.
Description
Technical field
The utility model relate to a kind of saline-alkali soil greening construction every alkali, row's alkali system.
Background technology
Because China coast urban economy increases fast, so construction of city afforestation is also particularly fierce, but the greening construction in a lot of saline land, coastal cities is due to every alkali, the measure of row's alkali is not in place, cause the salt-alkali contaminated very soon of the planting technique of replacing, cause the bad or large stretch of death of seedling growth, therefore the greening construction in saline land science, reasonable, rigorous construction technology measure and construction method must meet greening requirement.
Utility model content
The purpose of this utility model is for prior art Problems existing, provide a kind of saline-alkali soil greening construction every alkali, row's alkali system, guarantee that the planting soil changed is not salt-alkali contaminated, for the survival rate of nursery stock and normal growth escort.
For this reason, the utility model takes following technical scheme, saline-alkali soil greening construction every alkali, row's alkali system, comprise drainage pipeline system, it is characterized in that described drainage pipeline system comprises many arms, described arm is connected to supervisor, described supervisor is connected to gully, gully external connection row supply mains is connected to city planting ductwork, described supervisor, arm and main sewer are all buried underground in channels, described arm and supervisor are the blind pipe having through hole on its surface, fill medium coarse sand in described raceway groove.
The outside of described arm is surrounded by two layers of non-woven fabrics.Two layers of non-woven fabrics can stop that earth blocks pipeline
The outer end of described arm arranges plug.
Described arm at least tilts to supervisor with the centesimal gradient, and described supervisor also tilts to gully with at least centesimal gradient.
The top of described tubes rows water system arranges metalling.
Described metalling top arranges the plantation soil layer in order to replace saline-alkali soil, arranges barrier film between described plantation soil layer and the saline and alkaline soil layer of external boundary.
Described barrier film is Polypropylence Sheet or geomembrane cloth, and described barrier film is higher than the saline-alkali soil at least 200mm of external boundary.
Described arm diameter is 110mm, and the diameter of supervisor is 160mm, and described supervisor is pvc pipe or Double-wall PVC screwed pipe, and described supervisor and arm be spacing 30mm perforate on tube wall, and opening diameter is 8mm and is quincunx.The drain structure of this structure is beneficial to draining
The bottom of described plantation soil layer is 1000mm ~ 1500mm far from ground.
After the utility model delimit greening construction scope, excavation falls saline-alkali soil and re-lays drainage pipeline system, metalling and plantation soil layer.The saline-alkali water that saline-alkali soil below metalling is oozed out and planting soil down ooze out the moisture come and are reasonably diverted to drainage alkali raceway groove, then draining Pipe for draining alkali is infiltrated, house steward or draining alkaline discharging well is flow to by arm, be disposed to city planting ductwork again, avoid planting soil to pollute by saline-alkali water, the Heat resources Polypropylence Sheet of limit, greenery patches and saline-alkali soil or geomembrane Polypropylence Sheet are laid and can be completely cut off outer peripheral salt-alkali contaminated, thus guarantee nursery stock energy normal growth.
Accompanying drawing explanation
Fig. 1 is partial structurtes schematic plan view of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.
As shown in Figure 1, saline-alkali soil has been dug by planting soil desired depth in region, greenery patches, draining, row's alkali ditch and arm 1 are set, must by gradient slope aspect supervisor 2 erection of 1% when digging draining, row's alkali ditch and lay arm 1, supervisor 2 and supervisor row alkali ditch also set up by the gradient slope aspect gully 3 of 1%, be disposed to municipal Storm Sewer Network by main sewer 4 again, city planting ductwork also should be led to by the gradient of 1% in main sewer 4 and house steward drain ditch 5.Arm and supervisor are blind pipe, should install plug in blind pipe termination, and all blind pipes all need bag two layers of non-woven fabrics 6 outward, and draining is clapped in alkali raceway groove and filled the thick medium coarse sand of 150mm.
As shown in Figure 2, complete draining, after row's alkali ditch, pipe, spread medium coarse sand 7, then return the mat formation wide Polypropylence Sheet of 1500mm ~ 1800mm or geomembrane cloth 8 of side and saline land intersection in greenery patches and do every alkaline treatment, and the 200mm that should turn over suitable for reading is high, in case the inflow of outside buck.Again the thick metalling 9 (Φ 5 ~ Φ 10mm) of substrate paving 200mm, finally fill out planting soil 10 kinds and plant nursery stock.
Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
