Abstract
The invention relates to a water and soil conservation method capable of combining wells and channels used for plain areas. The water and soil conservation method is characterized in that a trench (6) capable of connecting drainage channels (1) and wells (5) is excavated between the drainage channels (1) and the wells (5) according to a certain hydraulic slope at the bottom of the drainage channels (1); one end, at the drainage channels (1), of the trench (6) is higher than the other end, at the wells (5) of the trench (6); cotton straws (4) are placed at the bottom of the trench (6) to be used as a hydraulic connection passage; a fine sand inverted filtering layer (2) is arranged at the water inlet end of the trench (6) to enable the inverted filtering layer (2) and the cotton straws (4) to jointly form a drainage body (7); the cotton straws (4) are cut into 4-6 cm straw sections; the straw sections are coated with cement paste for reinforcing corrosion prevention property; and then non-woven bags (3) are filled with the cotton straws (4) to obtain the drainage body (7). The water and soil conservation method is simple in process, convenient to construct, rapid in water storage and water source supplementation, capable of using local materials, low in cost and high in benefit, and easy to realize popularization and utilization.
Description
Technical field
The invention belongs to hydrotechnics field, particularly relate to the soil and water conservation method that a kind of region of no relief well trench combines.Soil keeps that retaining is short oozes field, is the irrigation canals and ditches backwater of a kind of rapid drainage field, increases surface flow and infiltrate on the spot fast, realize surface water and groundwater and directly change, improve that the water and soil conservation retaining of water resource spatial and temporal distributions is short oozes new method.
Background technology
The feature that Plain coastal region ubiquity irrigation canals and ditches density is high, motor-pumped well is widely distributed, the groundwater depression cone caused greatly due to rapid economic development, agricultural irrigation water amount again spreads all over, and agriculture irrigation canals and ditches median year exists a large amount of surface flow backwater and soil percolation water outlet.Trench depth is generally at 1 ~ 2 meter, because trench bottom is subject to effect of reservoir siltation for many years, soil aperture is little, add that leakage supply capacity is poor, hydraulic connection between surface water and groundwater is constantly weakened, cause water-holding capacity to be deteriorated, a large amount of surface water is converted into atmospheric water by evaporation and is difficult to utilize, and effectively can not mend source.The feature high in conjunction with region of no relief irrigation canals and ditches density, motor-pumped well distribution is many, by setting up efficient between a kind of surface water and groundwater, direct communication, break the permeation barriers existed between the two, reduce the drain evaporation of surface flow, make it be converted into underground water by surface water fast to carry out storing or recycling, water conservation.
Summary of the invention
The soil and water conservation method that a kind of region of no relief well trench that the object of the invention is to provide for the contradiction existed between a large amount of evaporation loss of region of no relief irrigation canals and ditches surface water and groundwater depression cone retaining benefit source combines.The method is that irrigation canals and ditches and well combine, and sets up water stream channel between the two, thus realizes that surface flow infiltrates on the spot, the function of water conservation.Realizing the technical scheme that object of the present invention takes is: the soil and water conservation method that a kind of region of no relief well trench combines, the method includes escape canal and well, it is characterized in that: in the bottom of escape canal, excavate the groove of a contact escape canal and well according to certain hydraulic gradient between escape canal and well, groove in one end of escape canal higher than the one end at well, channel bottom lays cotton stalk, as hydraulic connection passage, the water inlet end of groove lays fine sand loaded filter, makes loaded filter, cotton stalk forms water discharging body jointly.Described cotton stalk is cut into the stalk section of long 4 ~ 6 centimetres, is to strengthen antiseptic power, and stalk section is superscribed cement paste, after cotton stalk be filled in non-woven bag make water discharging body, water discharging body diameter or length and width control at 40 ~ 60 centimetres.
By application the present invention, make surface and ground water produce hydraulic connection, realize the object in retaining and the source of benefit to greatest extent.
Advantage of the present invention is: technique is simple, constructability, and it is rapid that source is mended in retaining, and gather materials on the spot, cost saving effect is grand, is easy to utilization and extention.
accompanying drawing illustrates:
Fig. 1 is soil and water conservation system structural representation of the present invention.
In figure: 1, escape canal, 2, loaded filter, 3, non-woven bag, 4, cotton stalk, 5, well, 6, groove, 7, water discharging body.
detailed description of the invention:
With reference to accompanying drawing, the soil and water conservation method that a kind of region of no relief well trench combines, the method includes escape canal 1 and well 5, it is characterized in that: in the bottom of escape canal 1, excavate the groove 6 of a contact escape canal 1 and well 5 according to certain hydraulic gradient between escape canal 1 and well 5, groove 6 in one end of escape canal 1 higher than the one end at well 5, cotton stalk 4 is laid bottom groove 6, as hydraulic connection passage, the water inlet end of groove 6 lays fine sand loaded filter 2, makes loaded filter 2, cotton stalk 4 composition water discharging body 7 jointly.Described cotton stalk 4 is cut into the stalk section of long 4 ~ 6 centimetres, is to strengthen antiseptic power, and stalk section is superscribed cement paste, after cotton stalk 4 be filled in non-woven bag 3 make water discharging body 7, water discharging body 7 diameter or length and width control at 40 ~ 60 centimetres.
By application the present invention, make surface and ground water produce hydraulic connection, realize the object in retaining and the source of benefit to greatest extent.
Innovative point of the present invention is as follows:
A, to be coordinated by irrigation canals and ditches, well, solve surface flow safety, effectively, the difficult problem in lower impregnation source fast, more traditional pure trench bottom seepage water conservation efficiency is higher, more direct;
Water resource in the existing irrigation canals and ditches of b, efficiency utilization, decreases Water Evaporation loss, advocates surface flow and accumulates utilization locally, and it is effective to recharge benefit source;
C, adopt local cheap cotton stalk, realize changing waste into resources utilize, cotton stalk water discharging body utilization periods is high, loaded filter exchange filling just, greatly reduce build and manage and protect cost, safeguards system long-term stability play effect;
D, change runoff row lead direction, the runoff that horizontal direction drain change into vertical accumulation, under ooze, benefit source, set up surface water, underground water rapid translating passage, maintain surface water resources and groundwater resources product, store balance;
E, by increasing surface water leakage, effectively reducing the water level in Soil Surrounding, indirectly slowing down periphery Farmland Salinization and threatening.
