Abstract
The utility model relates to a mechanical and electrical product, in particular to a cage type agricultural well pipe which is characterized in that: the main body of the well pipe is a cage-shaped skeleton (1) formed by a plurality of support rings (3) and a plurality of long and thin vertical rods (4) via connection; and a filter screen (2) wraps the periphery of skeleton (1). The cage type agricultural well pipe has the beneficial effect of being sufficient in strength, high in porosity, consistent in pore size, uniform in distribution, good in water permeability and filterability and convenient for manufacturing and mounting; and the cage type agricultural well pipe can be immediately manufactured at the mounting site, so that the comprehensive cost is lower than that of the existing cement well pipes, the cost performance is markedly increased and the market prospect is very considerable.
Description
Technical field
The utility model relates to a kind of agricultural equipment, the agricultural well casing of promptly a kind of cage.
Background technology
In recent years, the pumping irrigation well water yield in many drought-resistant agriculture district obviously descends, and working life and update cycle obviously shorten.Research shows: the motor-pumped well water yield reduces, except groundwater resources reduce, and drawdown, outside the hydraulic pressure reduction of well week, the porosity of the quality problems of well casing, particularly tube wall is too low, also is a major reason.The well casing of existing pumping irrigation well is many to be processed by cement and sandstone, is commonly called as the cement well casing.Many holes are arranged on the tube wall of cement well casing, and the size of these holes, distribution and total amount all must be suitably.Hole is excessive or too much, can reduce intensity, also can infiltrate silt, silts well casing up.Hole is too small or very little, can reduce water yield., it is very very difficult making the hole index of tube wall just right.We know; The hole of cement well casing forms in forming process naturally; The forming process situation is complicated, and the factors such as mode of the ratio of various raw materials, the degree of mixing and moulding are all very uncertain, and formed pore size and distribution situation and porosity all are difficult to control.Shortcomings such as therefore, the cement well casing is difficult to satisfy increasingly high quality requirement, and to exist weight big for the cement well casing in addition, and cost of transportation is high, and installation difficulty is big continue to use to be restricted.In this case, find better than cement well casing performance, the substitute that cost is lower is one of research direction that improves the pumping irrigation well operating efficiency.
Summary of the invention
It is enough that the purpose of the utility model provides a kind of intensity, and porosity is high, and pore size is consistent, is evenly distributed, and water permeability and strainability are good, and the lower pumping irrigation well well casing of cost.
Above-mentioned purpose is realized by following technical scheme: develop the agricultural well casing of a kind of cage, be characterized in: the main body of said well casing is a plurality of support rings and many cage shape skeletons that elongated vertical rod is formed by connecting, the peripheral parcel of skeleton filter screen.
Said support ring is a reinforced steel bar ring, and said vertical rod is a reinforcement rod, and wherein each reinforced steel bar ring horizontal successively up and down is connected with the reinforcing bar vertical rod that is uniformly distributed with all around mutually.
Said skeleton two ends are provided with junction plate, have connecting hole on the junction plate.
Said support ring is the bamboo ring, and said vertical rod is bamboo bar or rod.
Said support ring is a plastic hoop, and said vertical rod is a plastic bar.
Said support ring is a cement sheath, is uniformly distributed with a plurality of jacks that match with vertical rod all around.
Said filter screen is the grid lining that is formed by many filament interconnections.
Said filter screen be copper gauze, plastic wire, brown rete cutaneum, nonwoven one of them or two or more.
The beneficial effect of the utility model is: intensity is enough, and porosity is high, and pore size is consistent; Be evenly distributed, water permeability and strainability are good, and manufacturing is installed all very convenient; And can make immediately in the erecting bed; Integrated cost is lower than existing cement well casing, and cost performance significantly improves, and market prospects are very considerable.

The specific embodiment
First kind of embodiment: as shown in Figure 1, this well casing is made up of skeleton (1) and filter screen (2), and filter screen (2) is trapped among the outside of skeleton (1).In conjunction with Fig. 2,3 visible, skeleton (1) is to be formed by connecting the support ring (3) of a plurality of horizontal and many vertical rods (4).The above reinforcing bar welding of diameter 50mm is preferably adopted in support ring (3) and vertical rod (4), can certainly adopt other materials such as bamboo, timber, plastics, cement, magnesite to process.The diameter of skeleton should confirm by the diameter of pumping irrigation well, height so that degree of being operating as generally should about 4m, be advisable.The two ends up and down of each skeleton (1) all are provided with junction plate (5), and junction plate has connecting hole on (5), can connect with bolt or inserted link, junction plate (5) preferably three be uniformly distributed with so that butt joint.The grid lining that filter screen (2) can adopt many filament interconnections to form, for example the copper gauze more than 100 orders, plastic wire, brown rete cutaneum, nonwoven etc. all can.
In conjunction with the method for using of the visible this well casing of Fig. 4, at first get wellhole on the ground downwards with well sinker, then skeleton (1) is stood on well head; Send into wellhole behind the parcel filter screen (2); And dock with top skeleton (2) through bolt and junction plate (5), wrap up filter screen (2) again, by that analogy.After accomplishing the installation of well casing, with the sandstone particle space between well casing and the wellhole is filled up again and got final product.
The well casing skeleton (1) that second kind of embodiment: Fig. 5 representes also is to be formed by connecting support ring (3) and vertical rod (4), and support ring wherein (3) has (9) two kinds on reinforced steel bar ring (8) and bamboo ring.Vertical rod (4) also has (11) two kinds on reinforcement rod (10) and bamboo bar.The intensity of this structure can be satisfied the demand, and cost but can decrease.Certainly, here bamboo ring (9) and bamboo bar (11) also can replace with wood ring or rod.
The support ring (3) of the third embodiment: Fig. 6,7 expressions is prefabricated cement sheaths (12), has jack (13) on every side, during use, can vertical rod (4) be inserted in jack (13) and get final product.For easy for installation, jack (13) can be greatly, and reinject after vertical rod (4) is inserted cement and rapid hardening adhesive closure are fixed.
The form of cement sheath (12) also can have multiple, and like Fig. 8, shown in 9, cement sheath (12) is provided with boss (14), and this structure is suitable for skeleton (1) two ends, is convenient to the butt joint with adjacent skeleton.
Certainly, this cement sheath (12) also can use with reinforced steel bar ring (8) collocation.
