Abstract
The utility model relates to a farmland groundwater level monitoring device which comprises a cylindrical body, and is characterized in that a sealing cover is arranged at the upper opening of the cylindrical body, infiltration holes are formed on the circumference of the lower part of the cylindrical body, and a filter screen for preventing infiltration holes from blockage covers the peripheries of the infiltration holes. The device is prevented from being influenced by surface runoff when the groundwater level is monitored, is durable, and is low in cost and easy to observe.
Description
Technical field
The utility model relates to a kind of farmland water table measure device, is applicable to the farmland moisture condition monitoring.
Background technology
The drought in farmland, stain, waterlogging and farmland water level are closely related, under weather, the hydrology, geology and human factor influence, the farmland groundwater level changes in time, thereby to carry out the farmland water table measure be to understand the farmland moisture condition situation to take the effective means of necessary filling row measure.Water table measure device (inspection well) design at present needs the landfill sandstone, and is time-consuming, and application nylon filter cloth is subject to the earth obstruction as permeable outsourcing material.
Summary of the invention
The purpose of this utility model is to provide a kind of farmland water table measure device, and this device is not subjected to the influence of rainwash when the farmland underground water table is monitored, and with low cost, and water proof and wearable is observed simple and easy.
Of the present utility model being characterised in that: a kind of farmland water table measure device, comprise a cylindrical body, it is characterized in that: described cylindrical body upper shed is provided with gland bonnet, described cylindrical body bottom week side offer the infiltration hole, periphery, described infiltration hole is coated with the filter screen of the hole plug that prevents to seep water.
Described cylindrical body under shed is coated with filter screen, and described cylindrical body bottom is provided with the end cover that fastens its bottom and filter screen, and all sides are covered at the described end and the bottom offers the infiltration hole.
Described filter screen is made of palm leaf sheath fiber.
Advantage of the present utility model: one, be rich in new meaning, reasonable in design, observe simple and easy, and be not subjected to the influence of rainwash; Two, make full use of new material and rural area, agricultural wastes resource, efficiently solved the farmland underground water table and observe light simplification problem, had bigger application and popularization value.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the A-A cut-open view of Fig. 1.
Among the figure: 1 is cylindrical body; 2 is gland bonnet; 3 is filter screen; 4 are end cover; 11 are cylindrical body infiltration hole; 41 are cover infiltration hole, the end.
Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperate appended graphic being described in detail below.
With reference to figure 1 and Fig. 2, a kind of farmland water table measure device comprises a cylindrical body 1, it is characterized in that: described cylindrical body 1 upper shed is provided with gland bonnet 2, described cylindrical body 1 bottom week, side offered infiltration hole 11, and 11 peripheries, described infiltration hole are coated with the filter screen 3 of the hole plug that prevents to seep water.
Described cylindrical body 1 under shed is coated with filter screen 3, and described cylindrical body 1 bottom is provided with the end cover 4 that fastens its bottom and filter screen 3, and 4 all sides are covered at the described end and the bottom offers infiltration hole 41.
Described filter screen 3 is made of palm leaf sheath fiber.
In the utility model one preferred embodiment: described cylindrical body adopts pvc pipe (being about 150cm), below the about 70cm of distance pvc pipe upper shed position, offer infiltration hole (the about 1cm of diameter), cover of the described end is cut to put by the waste plastic bottle and is formed, filter screen uses palm fiber (palm leaf sheath fiber) bag to praise on pvc pipe and also binds in a down-to-earth manner, around reaching, waste plastic bottle bottom cuts some infiltrations hole (the about 1cm of diameter), both can allow water fully flow into pvc pipe, blocked sieve aperture by earth in the time of can preventing to imbed the farmland again, the accessory assembling with low cost and easy that this device uses.When using this device, at first, with scoop in conjunction with earth boring auger at the hole that bores on the farmland about an aperture and roughly the same, dark 120 cm of pvc pipe diameter, empty the interior earth of hole, pvc pipe is imbedded hole, stay the pipe of 30-60cm to basset.The soil of excavating is filled out Hui Yuankeng, and train high soil 20cm along pvc pipe.Gland bonnet is in sealing state at ordinary times, and anti-rainwater infiltrates in the pipe, and other makes a fine bamboo rod the same with this monitoring device length.When measuring underground water table, open gland bonnet, the bamboo bar is inserted pvc pipe fully, this moment, one end and the mouth of pipe of bar were fair fully, rise from the pipe face again, can see the moistening vestige of bar, the moistening vestige place of sounding rod is to the distance (a) of the dry end of bamboo stalk, expose the distance (b) of field face with pvc pipe and subtract each other, promptly get underground water table numerical value (a-b).
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
Claims (3)
