![]() Soil drain
专利摘要:
An earth drain which comprises a filter encased core having, on at least one base or web surface, a first array of discrete projections or studs of uniform height and a second array of discrete projections or studs of lesser height than the projections or studs of the first array. The projections or studs of the second array are so disposed between the projections or studs of the first array that, under relatively low pressures, the filter encasing the core is maintained in spaced relationship with the base or web of the core by the free ends of the first array of projections or studs and, at relatively high soil pressures, the filter material forced inwardly toward the base of the core is supported by the free ends of the studs of the second array and is thus maintained in spaced relationship with the base of the core, the spacing corresponding to the height of the second array of projections or studs. 公开号:SU890987A3 申请号:SU762386162 申请日:1976-07-23 公开日:1981-12-15 发明作者:Вагер Олег 申请人:Беркан Интернэшнл Лимитед (Фирма); IPC主号:
专利说明:
one The invention relates to land reclamation, namely to the drainage of soils having a low permeability. A soil drainage is known, comprising a flat core of water-permeable material with culverts and a filter 11. A disadvantage of the known drainage is low productivity and reliability. 10 The purpose of the invention is to increase productivity and reliability. This goal is achieved by the fact that on both surfaces of the heart there are projections of different height, located at equal distance from one another, with projections of the same height arranged in alternate longitudinal rows. The projections in adjacent rows are arranged in chess order. Through holes are made in the core. The lugs have a circular cross section.25 FIG. 1 dan is a drainage segment with a partially removed filter, top view; in fig. 2 - the drainage, section, showing the relationship between the core and the filter material at relatively low soil pressure; in fig. 3, the cross section in FIG. -1, showing the interaction between the core and the filter material at relatively high soil pressure; in fig. k modified core designs, cross section; Fig. 5 shows an embodiment of the drain including a modified con. the structure of the core (see FIG.), the cross-section, in FIG. 6 is a drain that is divided for insertion of a pipe, the cross section in FIG. five.
权利要求:
Claims (3) [1] The soil drain contains the core 1, the filter 2 in the form of a sheath of filter material that completely surrounds the core and passes water through itself, but does not allow particles, such as sand, clay, or the like. The core 1 has a relatively thin reamer (3 or base, on both sides of which there is a first row of projections i of the same height and a second row of protrusions 5 of the same height that are below the protrusions +. In the shown embodiment, the protrusions i and 5 are located at the same distance from each other in rows in the longitudinal and transverse directions relative to the bridge, and the longitudinal rows of projections k in such a way that each protrusion 5 is located centered relative to four adjacent projections k. of significant importance, although preferably in terms of ease of manufacture and operation. Further, it is not essential that the protrusions should be located on both surfaces of the 3f jumper, although the presence of protrusions on both surfaces is preferably in many cases due to double the flow area for the drainage water in comparison with the embodiment in which the protrusions are located only on one side of the surface of the jumper 3 in which it is made, there are through holes. Both core 1 and filter 2 can be made of any material suitable for this purpose. The core may be made of polyethylene, although any other suitable plastic or even metal, such as steel or aluminum, may be used, the filter may be made of suitable filter paper, which can be used to work under severe conditions, such as paper, used in industry for soil drains. The dimensions of the drains are not critical, although typical drains are about 1 mm thick and about 100 mm wide. The projections and 5 have a diameter of approximately 2 mm, the projections k have a height of approximately 2.5 mm, and the projections 5 have a height of approximately 1.25 mm. The distance A between the outer edges of the series of protrusions i and 5 is approximately twice the thickness of the filtering material, for example, in the range of 0 mm to minimize the chance of the filtering material coming into contact with the bridge under high soil pressure. Drain can have any length, for example 152 m and more. When making drains of such length, 8 8 .4 is forest-like so that the material from which the drains are made has relative flexibility so that it can be stored coiled or wound on a drum. Drena works as follows. When the soil is exposed to relatively low soil pressure, the filter is supported by the free ends of the projections k in such a way that between the projections there are free spaces, a passage for the drainage water is formed by a bridge and filter (see Fig. 1). When the drainage is exposed to relatively high soil pressure, the passage for drainage water is in some way restricted (see Fig. 3) in the sense that the soil pressure presses the filter material inward in the direction of the core web. However, when this occurs, additional or lower protrusions 5 provide additional support for these filter sections, which are pressed inward, and provided that the distance A is not more than twice the thickness of the filter material, it is almost impossible to put the filter material into contact with a bridge in order to completely close the passage for drainage water, even if the distance A is more than twice the thickness of the filter material, the arrangement of the protrusions is such that without breaking the filter it is almost impossible completely block the passage for drainage water. However, if this happens, holes 6 are provided in the web, connecting fluid passages on each side of the web. Various modifications are possible, both in shape and in position of the projections. The protrusions (see Fig. B3) have a circular cross section, although under certain circumstances another cross section, such as square, rectangular, cruciform, etc., may be considered preferable. In another embodiment (see Figs. K-6), the core consists of one bridge, which is equipped with protrusions and 5, spun out only on one side of it, and which is partially cut along the longitudinal center line to form a bend. The jumper portions on each side of the center line are identical, so that the jumper can be folded along a bend to form a core that corresponds to the core (see Fig. 1-3) as shown in Fig. 5. The advantage of the modified embodiment, in addition to the ease of manufacture of the core, is that the two halves of the core can be slightly apart (see Fig. 6) for insertion between the halves of a pipe or the like. Such a pipe can be used to inject chemicals, such as lime, through a drain to enhance the properties of the sludge located next to the drain. This invention improves the performance and reliability of the drain. Claim 1. Soil drainage comprising a heart from a waterproof material with culverts and a filter, characterized in that, in order to increase productivity and reliability of work, protrusions of different heights are arranged on both surfaces of the core, equally spaced. one from the other, with the protrusions of the same height arranged in longitudinal alternations of | qig "1 with rows.

Draining according to Claim 1, characterized in that through-holes are filled in the core. k. A drain according to claim 1, characterized in that the projections have a circular cross section.
