Description
Technical field
The utility model relates to a kind of saline land greening salt discharge system, belongs to the landscape engineering technical field.
Background technology
The saline land greening salt discharge is one of key measure of growing fine of plant.Urban landscaping often runs into many saline lands in building, and the greening difficulty is very big.The one big characteristics in saline land are exactly the subterranean water level height, have saline and alkaline moisture and use soil capillary to rise to the face of land, and after the water evaporates, the saline land can be trapped in the face of land, brings very big difficulty to greening work.Do not become system by the technology of laying the hidden pipe salt discharge in the past, do not reach long-term use, tackled the various good salt discharge effects that change naturally.
Summary of the invention
The purpose of this utility model is to provide a kind of saline land greening salt discharge system, in conjunction with advanced water conservancy salt discharge theory, carries out salt discharge at the rational drainage pipeline networks of underground laying.According to the water salt characteristics of motion of " salt comes with water, and salt goes with water ", lay hidden pipe the salinity in the soil drained with water, and with Groundwater Control below critical depth, reach the soil desalination and prevent saliferous purpose.
The technical solution of the utility model is as follows: a kind of saline land greening salt discharge system comprises saline and alkaline separation layer, salt discharge pipe, interlayer, pouring layer, plantation soil layer and salt discharge well.Described saline and alkaline separation layer, salt discharge pipe, interlayer, pouring layer, plantation soil layer are distributed in underground each layer in saline land to be afforested successively from the bottom to the upper strata, described salt discharge well is evenly distributed on the zone, saline land.
Described saline and alkaline separation layer is being cleared the saline land alkaline earth, on the basis, smooth place, is laid on the bottom in saline land.The degree of depth of clearing alkaline earth should adhere to specification, and accomplishes " to the end, to the limit, put in place ", to the smooth acceptance(check) in sectional dimension, elevation, bottom face of foundation trench.The used material of saline and alkaline separation layer is cinder, stone and stone nitre etc., and thickness is generally 15cm, and error band is at ± 1cm.By laying separation layer, prevent that original salinity of bottom, greenery patches from rising.Lay in the separation layer process, machinery, vehicle can not enter the greening place, avoid separation layer and bottom alkaline earth to force together, and lose or weaken buffer action.
Described salt discharge pipe divides to be responsible for and arm, and being responsible for and adopting 110mmUPVC grey feed pipe, arm is specialty infiltration ripple 32mm salt discharge pipe.The laying scope is according to green coverage size, spacing 4-5m.The person in charge should be lower than arm 10cm.The degree of depth of salt discharge pipe arm should be lower than planting soil 1m-1.2m.When laying the salt discharge pipe, check drawing earlier, the fixed point unwrapping wire; Fluting then, it is shallow to begin an end, terminal dark, for the ease of the control waviness, gets a control point, spot check absolute altitude every 3-5m; Lay the thick sand bedding course of 50cm, guarantee that salt discharge pipe bottom is stable; Salt discharge tube-surface parcel is laid, and prevents that fine grained soil from entering the salt discharge pipe, stops up the infiltration hole.The end absolute altitude of salt discharge pipe must be greater than discharge level, and the laying density of pipe and the gradient must meet the drawing requirement, lays spacing and is generally 5-10m, and the gradient is at 0.3%-0.8%, and the pipe fitting joint and the sleeve pipe of passing by on one's way all will be placed on request.
Described interlayer is used to isolate the salt discharge pipe and drenches layer, completely spreads the thick high-density polyethylene geomembrane of 2mm and one deck water drainage plastics clamping plate above the salt discharge pipe, prevents that the salt discharge pipe from being damaged by pressure by liquid slag or stone nitre etc.
Above described pouring layer is laid on after the water drainage plastics splinting layer is finished, earlier the salt discharge pipe trench is filled out extremely, the soil moved in to improve the original of both sides must not be sneaked into when backfill liquid slag or stone nitre and drench in the layer, otherwise can influence its effect.The laying depth that drenches layer should adhere to specification.
Described planting soil is after drenching above the layer, drenching layer acceptance(check), but the backfill planting soil, and slight compacting.But basal dressing carries out soil melioration before the planting soil backfill, and the amount of application of base manure wants strictness to carry out on request, after fertilizer evenly applies, requires unit in charge of construction to carry out mechanical agitation with suspend-tilling machine, ploughs rake three times repeatedly.Should consider the soil settlement factor during backfill planting soil, absolute altitude should adhere to specification during final acceptance of construction.
Described salt discharge well is provided with at the infall of salt discharge pipe and with other pipelines, facility infall, general dark 1.5m, and diameter 1.2m is 24 wall constructions.The spacing of salt discharge well is generally one of 30-40m.20cm foreign material precipitation is stayed in the bottom of salt discharge well.Stay 4-5 around the well and insert mouth, be used for arm and directly insert.Build by laying bricks or stones finish after, from the most significant end water filling, see whether water can verify its effect from the least significant end draining.
Though the urban landscaping difficulty in saline and alkaline area is very big,,,, still can realize afforesting and beautifying effect with the administrative skill of reasonably controlling salt, salt discharge measure and science according to the functional requirement and the soil condition of green belt as long as follow the water salt characteristics of motion.Use of the present utility model can realize the saline land greening salt discharge preferably, promotes the urban afforestation environmental protection, improves good human settlement.
