Description
Technical field
The present invention relates to the greening method in the waterproof salt-soda soil of a kind of high water level, also relate to a kind of greening system that adopts the waterproof salt-soda soil of high water level of this method, mainly be adapted to the greening in the salt-soda soil that viscosity is big, water level is high.
Background technology
The salt-soda soil exists at coastal region in a large number, and existence form also is not quite similar, and the method for therefore administering also is not quite similar; For example the soil in certain park, strand is rubbery black clay; Groundwater table is 20cm only apart from the face of land, soil compaction, and soil is moistening for a long time behind the rain; Surface pond is bronzing, and maintains the original state for a long time.Raining and wash away back testing soil pH value in the face of land is 8.6; Underground 20cm-60cm place soil salt content 0.42%; On this type soil; If adopt conventional trees planting patterns to be difficult to guarantee existence and the growth of trees, therefore be necessary to develop a kind of trees kind method for planting that is adapted to the clay salt-soda soil of this high water level.
Summary of the invention
In order to overcome the above-mentioned defective of prior art; The invention provides greening method and a kind of greening system that adopts the waterproof salt-soda soil of high water level of this method in the waterproof salt-soda soil of a kind of high water level, with survival and the growth of trees in the clay salt-soda soil that is adapted to high water level.
The present invention realizes that the technical scheme of above-mentioned purpose is:
The greening method in the waterproof salt-soda soil of a kind of high water level; It adopts the filling type gutter to carry out the draining salt discharge; The bottom of trench in said filling type gutter is embedded with blind pipe longitudinally; The top of said blind pipe is equipped with the infiltration sand bed, catchments and with in the infiltration hole introducing blind pipe of water through said blind pipe top through the infiltration sand bed, and the outfall through blind pipe enters drainage pipe and/or collecting well with water.
It is domatic that one or more filling type infiltrations can be set in the one or both sides of bottom, said filling type gutter; On said filling type infiltration is domatic the infiltration sand bed is set and this infiltration sand bed and the infiltration sand bed that is positioned at said blind pipe top are connected as a single entity; The infiltration of said filling type is domatic to extend to specific drainage; Said drainage can be provided with or also the sand bed that catchments can be set; Infiltration sand bed on said sand bed and the said filling type infiltration of catchmenting is domatic can be connected as a single entity usually, guides the water of said drainage into blind pipe through the domatic infiltration sand bed of filling type infiltration thus.
Preferably; On blind pipe both sides and top with rubble soft flocks landfill; The said infiltration sand bed that is positioned at blind pipe top be laid immediately on said rubble soft flocks above, the water in the sand bed that will seep water thus infiltrate said blind pipe around also through in the entering of the infiltration hole on the said blind pipe blind pipe.
The greening system in the waterproof salt-soda soil of a kind of high water level; It is provided with the filling type gutter, and the bottom in said filling type gutter is embedded with blind pipe longitudinally, and the top of said blind pipe is furnished with the some infiltrations hole that penetrates its tube wall; The bottom of said blind pipe is provided with the outfall that is communicated with collecting well or drainage pipe; It is domatic that the bottom margin in said filling type gutter connects oblique upwardly extending filling type infiltration, and the bottom in the domatic and said filling type of said filling type infiltration gutter is equipped with the infiltration sand bed, and said blind pipe is positioned at the below of the infiltration sand bed of bottom, said filling type gutter; Tamp with soil the top of said infiltration sand bed, can be filled to concordant with ground surface usually.
The outside of said blind pipe can be provided with the silk screen that covers said infiltration hole usually, to avoid earth permeable hole is clogged.The both sides of said blind pipe and top are by rubble soft flocks landfill; Formation is trapped among the rubble soft flocks layer around the said blind pipe; Said infiltration sand bed be laid immediately on said rubble soft flocks layer above; Thus above blind pipe and around form good infiltration zone, to realize catchmenting and purpose through the permeable hole draining.
Said infiltration sand bed preferably adopts thick river sand, oozes/permeable effect with raising.
The thickness that is positioned at the said rubble soft flocks layer of said blind pipe top can be 1-10cm usually, can form good oozing/permeable effect thus.Simultaneously, match, can form good penetration and filter effect with the thick river sand that constitutes said infiltration sand bed.
The thickness of said infiltration sand bed can be 8-25cm usually, has both guaranteed thus to ooze/permeable effect, avoids blocked up sand bed to influence root growth again.
Said blind pipe can be the cement blind pipe usually, reducing the cost, and increases the service life.
The external diameter of said blind pipe can be 15-40cm usually.
The domatic gradient of said filling type infiltration can be the 5-45 degree usually; Can confirm as the case may be; The water that can effectively the zone that needs draining be oozed out is thus introduced the filling type gutter; And then entering collecting well or drainage pipe through blind pipe, said drainage pipe can adopt existing municipal drainage pipeline.
The invention has the beneficial effects as follows: owing to be provided with the filling type gutter and in the filling type gutter, buried the blind pipe of infiltration usefulness underground; And be provided be used to catchment with permeable infiltration sand bed; Can water be collected in the infiltration sand bed and then through blind pipe thus and discharge, realize carrying out the purpose of draining and salt discharge thus at regional area; Owing to can with the infiltration sand bed of infiltration on domatic the water of close region be introduced in the gutter through infiltration is domatic; Can realize draining thus, this drainage pattern is applied in the trees plantation the specific region, can be with the water in the plant pit through the domatic introducing of infiltration; When this drainage pattern is applied to roadbed and wall base protection; Can near the ponding draining the roadbed and the wall base be reduced these regional water levels, can be conveniently implemented in many-sided application thus.
Description of drawings
