Abstract

The utility model discloses a salt and alkali discharge pipe used in a saline-alkali land. The salt and alkali discharge pipe comprises a pipe body. A plurality of salt and alkali discharge hole groups are evenly distributed on the wall of the pipe body along the axial direction of the pipe body. Each salt and alkali discharge hole group comprises a plurality of salt and alkali discharge holes which are evenly distributed along the circumferential direction of the pipe body. Seepage-proofing film strips corresponding to the salt and alkali discharge holes are disposed on the outer wall of the pipe body. The salt and alkali discharge pipe used in the saline-alkali land is simple in structure, convenient to use, maintain and manage, and low in cost. Moreover, the salt and alkali discharge pipe used in the saline-alkali land saves water resources and has high practical applicability.

Description

The saline land is with salt discharge alkali pipe

Technical field

The utility model relates to salt discharge alkali Manifold technology field, relates in particular to a kind of saline land with salt discharge alkali pipe.

Background technology

The saline land is a kind of salt aggregation, is meant that the contained salinity in soil the inside has influence on the normal growth of crop, and up to 9,913 ten thousand hectares, basicity is generally higher at the area in China saline land, and serious salt affected soil regional plant almost can not be grown.Therefore, the improvement in saline land and utilization, to the protection of ecotope, the development of urban economy all is an extremely important problem.

Measures such as alkali, big hydraulic pressure alkali, raised fields row alkali are arranged in prior art open drains of adopting when the improvement saline land more; Though these several kinds of modes can reduce the basicity of soil effectively, its water consumption is big, and the water resource waste situation is serious; And because phreatic reverse osmosis effect; When stopping to pour water, soil is easy to by salinization of soil once more, makes that the cost of soil melioration is too high.

The utility model content

The utility model technical problem to be solved is: provide a kind of saline land with salt discharge alkali pipe, can reduce the basicity of soil effectively.

For solving the problems of the technologies described above; The technical scheme of the utility model is: the saline land is with salt discharge alkali pipe; Comprise salt discharge alkali body; The tube wall of said salt discharge alkali body is provided with some along the salt discharge alkali hole group that it axially is uniformly distributed with, and each said salt discharge alkali hole group comprises the salt discharge alkali hole that a plurality of edges said salt discharge alkali body circumferentially is uniformly distributed with, and the outer wall of said salt discharge alkali body is provided with and the corresponding antiseepage film bar in said salt discharge alkali hole.

Preferably, said salt discharge alkali body is pvc pipe or PE pipe.

After having adopted technique scheme; The beneficial effect of the utility model is: owing on the tube wall of salt discharge alkali body, offered some along salt discharge alkali hole group that it axially is uniformly distributed with; Each salt discharge alkali hole group comprises a plurality of salt discharge alkali holes that circumferentially are uniformly distributed with along salt discharge alkali body; Then infiltration can be gone in the salt discharge alkali body through salt discharge alkali orifice flow; And then be discharged in the alkaline discharging well that connects the operation area through salt discharge alkali body, simultaneously, the antiseepage film bar that is arranged on the salt discharge alkali tube wall can prevent that silt from stopping up salt discharge alkali hole.

Because what salt discharge alkali body adopted is pvc pipe or PE pipe, not only cost of manufacture is low, and has intensity preferably, can guarantee the normal use of salt discharge alkali pipe.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the vertical section structural representation of the utility model embodiment;

Fig. 2 is the cross section structural representation of the utility model embodiment;

Among the figure: 1. salt discharge alkali body; 2. salt discharge alkali hole; 3. antiseepage film bar.

Embodiment

Shown in Fig. 1 and Fig. 2 are common, be respectively vertical section and the cross section structural representation of saline land with a kind of embodiment of salt discharge alkali pipe, this saline land comprises salt discharge alkali body 1 with salt discharge alkali pipe; On the tube wall of salt discharge alkali body 1, be provided with the saline and alkaline hole of plurality of rows group; These salt discharge alkali hole groups evenly distribute along the axis of salt discharge alkali body 1, and each salt discharge alkali hole group comprises a plurality of salt discharge alkali hole 2, and same group salt discharge alkali hole 2 circumferentially evenly distributing along salt discharge alkali body 1; The salt discharge alkali body 1 here can adopt pvc pipe or PE pipe; Not only cost of manufacture is low, and has intensity preferably, can guarantee the normal use of salt discharge alkali pipe.

On the outer wall of salt discharge alkali body 1, also be provided with the many antiseepage film bars 3 corresponding with salt discharge alkali hole 2; Every antiseepage film bar 3 covers the outside in the salt discharge alkali hole 2 corresponding with it respectively; And the antiseepage film bar 3 preferred antiseepage film bars that adopt the nonwoven material, like this, infiltration can flow in the salt discharge alkali body 1 through salt discharge alkali hole 2; And then be discharged in the alkaline discharging well that connects the operation area through salt discharge alkali body 1, the antiseepage film bar 3 that is arranged on salt discharge alkali body 1 outer wall can prevent that silt from stopping up salt discharge alkali hole 2.

This saline land is simple, easy to use with salt discharge alkali tubular construction, is convenient to maintenance and management, and its conserve water resource, and cost is low, has very high practicality.

The utility model is not limited to above-mentioned embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection domain of the utility model.
