Abstract
The invention discloses a technical method for draining saline and alkali in a blind well and a blind ditch, belonging to the field of water conservancy. A central point is selected in a land block with heavy saline-alkali, a well is drilled at the central point, the lowest end of a well pipe is provided with a sand settling pipe and a strainer, a filtering and precipitating device is arranged at a well head, a plurality of ditches are radially dug by taking the well head as the center, filtering materials are filled around the sand settling pipe, the strainer, the well head filtering and precipitating device and the dug ditches as required, the dug soil is backfilled, and the soil is restored to the original state. The salt and alkali removing system for the farmland consists of the blind wells and the blind canals, can conveniently solve the technical problem that the saline and alkali of the farmland can not be heavily harvested, saves manpower and material resources and enhances soil fertility compared with other salt and alkali preventing and treating methods, is easy to obtain and purchase materials, is easy to implement and is beneficial to wide implementation.
Description
1, technical field: staple shaft closed conduit salt discharge alkaline process of the present invention belongs to the water conservancy field.
2, background technology: the conventional method of farmland salt discharge alkali is the irrigation canals and ditches that dig salt discharge alkali in the farmland all around, then adopt the method for digging the canal machine or manually deep-cutting cool solarization backfill for indivedual saline and alkaline heavy field soil that do not go out the crops, many places have been deep-cut continuously and also still can not planted the crops several times.This kind way had both been taken manpower and materials, caused the reduction of soil fertility again and weakened, produce effects and act on little, the demand of incompatible modernization agricultural.
3, summary of the invention: the invention reside in the technical method that a kind of staple shaft closed conduit formula salt discharge alkali is provided, can solve the saline and alkaline heavy technical problem that does not go out the crops of field soil easily.
The technical method of staple shaft closed conduit salt discharge alkali of the present invention, its concrete technical scheme is: form farmland salt discharge alkali system by the staple shaft closed conduit, select a central point in saline and alkaline heavy plot, beat the well of a glance salt discharge alkali at central point, well casing be provided with desilting pipe and filter pipe bottom, well head is provided with filtering-depositing device, with the well head be the center be radial ditching canal several; Filling filtering material on request around desilting pipe and filter pipe, the well head filtering-depositing device and in institute's ditching canal, the soil that backfill is dug out and the land restoration former state.
Staple shaft closed conduit salt discharge alkaline process is compared and can be saved a large amount of soils with digging salt discharge alkali irrigation canals and ditches, and digs the canal machine or manually deep-cuts cool method of shining backfill and compare and can save lot of manpower and material resources and strengthen soil fertility, can reach salt discharge alkali effect preferably.
Owing to carry out such scheme, the present invention can solve the saline and alkaline heavy technical problem that does not go out the crops of field soil, implements this programme, and the material various places are easy to get and easily purchase, and cost is relatively low, helps promoting and extensively implementing.
4, the specific embodiment: select a central point in saline and alkaline heavy plot, beat a glance well at central point, the degree of depth of well is advisable to reach water table, can be according to circumstances in the well with condition different under materials used for cement pipes or plastic pipe as aquaporin down, what the condition difference was a little can also descend materials such as brickbat or cobble; Well casing be provided with desilting pipe and filter pipe bottom, filter pipe should have reliable intensity and anti-corrosion, endurance quality; The desilting pipe should have bigger capacity and suitable length, can gravel filter or the non-gravel of filling out filters with filling out around the desilting pipe, and the former is applicable to that the moisture latter of sand class is only applicable to gravel layer; Well head is tens of centimetres in the bottom, ground, are provided with filtering-depositing device at well head, are filtering materials such as cobble around the filtering-depositing device; With the well head be the center be radial dig the dark irrigation canals and ditches of tens of centimetres several, filling one deck sandstone etc. are made filtering material, the earth material that digs out of backfill and the plot recovered former state then, well becomes underground staple shaft, canal becomes kanat, has increased soil gas permeability and infiltration ability, and is saline and alkaline next with water, saline and alkalinely go, thereby reach salt discharge alkali effect preferably with water.
Example: Tarim Basin in Xinjiang, the native crops of the saline and alkaline kind of this technical method venting can be adopted in a large amount of saline and alkaline heavy plot that do not go out the crops: the degree of depth of well two, the three meters water tables of arriving that generally go down from ground, well head is generally at bottom, ground 50-80 centimetre, the degree of depth of irrigation canals and ditches is about 50 centimeters, filtrate bed course general thickness 10-20 centimetre, tens to more than hundred square metres ground very much not goes out the crops and only needs the little staple shaft of a glance, several little closed conduits because of saline and alkaline.Dig general dark is about 25 centimeters owing to plow, and staple shaft closed conduit row alkaline process is to the not influence of farmland agricultural, thus a kind of method preferably of can yet be regarded as, extensively promotion and implementation.
Claims (3)
1, a kind of technical method of staple shaft closed conduit salt discharge alkali is characterized in that: the staple shaft closed conduit has been formed the salt discharge alkali system in salt-soda soil, farmland, utilizes the staple shaft closed conduit to increase the gas permeability and the infiltration power in soil.
2, the technical method of staple shaft closed conduit salt discharge alkali as claimed in claim 1, it is characterized in that: staple shaft is underground at farming operation face, make salt discharge alkali passage with materials such as pipe of cement or plastic pipes, well casing is provided with desilting pipe, filter pipe, well head and is provided with filtering-depositing device, has the function of salt discharge alkali.
3, the technical method of staple shaft closed conduit salt discharge alkali as claimed in claim 1, it is characterized in that: closed conduit is underground at farming operation face, is filled with filtering material as the trap drainage layer, possesses the function of salt discharge alkali.
