Abstract
The utility model provides an alkali and water drainage structure for a tree underground tunnel. The alkali and water drainage structure for the tree underground tunnel comprises a broken stone scrap layer, an alkali drainage groove is formed in the upper layer of the broken stone scrap layer, a water filtering layer is arranged at the bottom of the alkali drainage groove, and a drainage pipe is arranged in the water filtering layer. The alkali and water drainage structure for the tree underground tunnel has the advantages that salt and alkali in soil can be drained in a nearby municipal administration rainwater pipeline through a drainage pipe, and the salt and alkali content in the soil can be effectively reduced; due to the fact that the water filtering layer is arranged, the salt and alkali in the soil can be effectively prevented from returning to a planting soil layer and affecting living and growing of the green plants.
Description
Technical field
The utility model relates to row alkali greening technique field, saline land, especially relates to row's alkali, the discharge structure in a kind of trees tunnel.
Background technology
Along with social development, afforestation no longer is confined to certain regional area, but expands to larger scope, more focuses on Ecological Construction.As being located in the salt affected soil area, more want the developing ecology greening, improve the health of human settlement and the ecosystem.
Saline and alkaline when too much in soil, will endanger the normal growth of plant, therefore arranging alkali is that salt affected soil is afforested most important link, directly have influence on surviving of nursery stock, how salt affected soil is arranged to alkali, in order to carry out the greening of full wafer greenery patches on salt affected soil, become current afforestation industry technical problem urgently to be resolved hurrily.
Summary of the invention
Problem to be solved in the utility model is to provide row's alkali, the discharge structure in a kind of trees tunnel, effectively saline and alkaline in soil discharged, isolates, guarantees the normal growth of plant.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: row's alkali, the discharge structure in a kind of trees tunnel, comprise one deck stone fragment layer, and the upper strata of stone fragment layer is provided with row's alkali ditch, bottom at row's alkali ditch is provided with the drainage layer, in the drainage layer, is provided with drainpipe.
Further, the longitudinal cross-section of row's alkali ditch is trapezoidal.
Further, the drainage layer comprises the first drainage layer and the second drainage layer.Here the first drainage layer and the second drainage layer all are filled with stone fragment, and the first drainage layer is different with the density of the stone fragment of the second drainage layer filling, and drainpipe is layed in to one deck that stone fragment density is larger.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, saline and alkaline in soil can enter municipal storm sewer nearby by drainpipe, effectively reduces the salt alkali content in soil; And arranging of drainage layer can effectively prevent from returning the plantation soil layer on saline and alkaline in soil and affect surviving and growing of green plants.

Embodiment
As shown in Figure 1, the utility model provides row's alkali, the discharge structure in a kind of trees tunnel, comprises one deck stone fragment layer 3, and the upper strata of described stone fragment layer 3 is provided with row's alkali ditch 1, and the bottom of described row's alkali ditch 1 is provided with drainage layer 2, in described drainage layer 2, is provided with drainpipe 4.The longitudinal cross-section of row's alkali ditch 1 is trapezoidal.Drainage layer 2 comprises the first drainage layer 21 and the second drainage layer 22.
The work progress of the utility model row alkali discharge structure: first with excavator, clear alkaline earth; Recharge one deck stone fragment; Above the stone fragment layer, backfill is applicable to the soil of green plants growth.Then use machinery or artificial mode to excavate a plurality of row's alkali ditches 1, in the bottom of row's alkali ditch 1, be provided with the first drainage layer 21 and the second drainage layer 22.Here the first drainage layer 21 and the second drainage layer 22 all are filled with stone fragment, and the first drainage layer 21 is different with the density of the stone fragment that the second drainage layer 22 is filled, when laying, the stone fragment density of the first drainage layer 21 is greater than the density of the stone fragment of filling with the second drainage layer 22, at the interior laying drainpipe 4 of the first drainage layer 21; Otherwise the stone fragment density of the second drainage layer 22 is greater than the density of the stone fragment of filling with the first drainage layer 21, at the interior laying drainpipe 4 of the second drainage layer 22.Saline and alkaline in soil can enter municipal storm sewer nearby by drainpipe 4, effectively reduces the salt alkali content in soil; And arranging of drainage layer can effectively prevent from returning the plantation soil layer on saline and alkaline in soil and affect surviving and growing of green plants.After drainpipe 4 has been laid, be about to this row's alkali ditch 1 and be used for planting green plants as treehole.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
