Abstract

A foaming weep drain made from both the plastics and the rubber, belonging to a hollow cavity tube, of which the tube wall is divided into the water penetration layer and the hollow cavity layer from outside to inside. Countless micro-holes are overspread around the tube wall and could be only observed with the help of 10 swung dash 20 x magnifier. Such micro-holes belong to the out-of-shape capillary bores which infiltrate water. The tube wall is made from the expanded materials via the mixing of both the plastics and the rubber, so, the layering is not naturally achieved. The plastics and the rubber are tightly united and interpenetrated; the foaming produces the micro-holes, so as to effectively safeguard against the jam inside the tube wall due to the accumulation of the incrustation, the silt and the plant roots. Meanwhile, the utility model has the advantages of very low working pressure, water-saving, energy-saving, long service life and low cost. Such utility model is mainly buried underground and used for the plant irrigation in the sunlight greenhouse, the orchard, the lawn, the green belt and the sand control project, etc.

Description

Mould rubber blend foaming soakaway trench

Technical field

The utility model relates to the Water saving type watering arrangement in a kind of agricultural, environmental protection greening field, is specifically related to a kind of rubber blend foaming soakaway trench of moulding.

Background technology

China's micro irrigation technology is started in the 1950's, but development is very slow always, and agricultural are irrigated has only purling and sprinkling irrigation, just development to some extent after introducing Mexico's micro irrigation technology in 1974.Infiltrating irrigation also is a kind of of slight irrigation, is present water saving, the highest water-saving irrigation technique of energy-conservation availability.Because external product costs an arm and a leg, to promote for many years, it does not obtain fine application in China.

China is one of 13 poor-water states in the world, and Chinese Water Conservancy portion drops into huge fund for solving the water-saving irrigation problem of northern area.According to Ministry of Water Resources's incomplete statistics, 300,000,000 mu of water-saving irrigation projects have been developed in the whole nation at the bottom of calendar year 2001, and wherein infiltrating irrigation is 4,500,000 mu, has promoted the process of China's agricultural water conservation whereby.In demonstration program, find that the soakaway trench infiltration is uneven or serious by silt and plant root whisker obstruction, service life is short, complex production process, the shortcoming that processing charges is high.Utilize on the spot through in the past few years production, still can not solve infiltrating irrigation at present and not stop up, and long service life and inexpensive new product.

The utility model content

In order to overcome the deficiency that existing soakaway trench easily stops up, the life-span is short, expense is high, the utility model provides a kind of rubber blend foaming soakaway trench of moulding, and this soakaway trench can effectively prevent to stop up, and water-saving consumption-reduction, life-span are long and inexpensive.

The technical scheme that its technical problem that solves the utility model adopts is as follows:

A kind of rubber blend foaming soakaway trench of moulding is the hollow lumen, and its tube wall from outward appearance to inner essence is followed successively by:

1. face seeps water: this infiltration face surface be covered with naked eyes invisible only can be under 10-20 times of magnifying glass can obvious clear demonstration countless micropores, these micropores are infiltration pore in irregular shape;

2. cavity face: this cavity face is the soakaway trench inner surface, this inner surface be covered with naked eyes invisible only can be under 10-20 times of magnifying glass can obvious clear demonstration countless micropores, these micropores are littler than the micropore of infiltration face, are infiltration pore in irregular shape.

To exosmosis, infiltration face was combined closely with the cavity face in described soakaway trench tube wall was served as reasons.

The invisible countless irregular infiltration pores of people's naked eyes have been covered with owing to mould the tube wall of rubber blend foaming soakaway trench at the utility model, water is after infiltrating under the very little water pressure and hastening towards saturation in managing, capillary disjunctor with soil, because siphonage, water just oozes out along all directions around the tube wall, moistening soil absorbs for root system of plant, thereby reaches irrigation purposes.The utility model soakaway trench infiltration face combines closely with the cavity face, interpenetrates, and can effectively prevent the obstruction that inside pipe wall incrustation scale, silt and plant root whisker cause.Mould the rubber blend and add foaming, rubber is added in the production process of plastics, can not produce natural layering, even foaming and rubber and plastic is combined closely, do not produce the gap, make the stable and uniform more that seeps water, performance indications such as tubing is ageing-resistant, frost resistance, corrosion resistance, mechanical strength are obviously improved.

The beneficial effects of the utility model are:

1, can ooze out around the soakaway trench tube wall equably under the situation that low pressure supplies water, moistening soil absorbs for root system of plant, realizes water-saving irrigation.

2, soakaway trench tube wall natural layering does not cause incrustation scale, is difficult for stopping up.

3, the theoretical life-span of soakaway trench can be higher than 6 years, and cheap.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Figure 1 shows that the utility model moulds an embodiment of rubber blend foaming soakaway trench, this soakaway trench is a hollow circular tube, and its tube wall from outward appearance to inner essence is followed successively by shown in Figure 2:

1, infiltration face 1: be covered with on this infiltration face surface naked eyes invisible only can be under 10-20 times of magnifying glass can obvious clear demonstration countless micropores, these micropores are infiltration pore 3 in irregular shape shown in Figure 3.

2, the cavity face 2: this cavity face is the soakaway trench inner surface, this inner surface be covered with naked eyes invisible only can be under 10-20 times of magnifying glass can obvious clear demonstration countless micropores, these micropores are littler than the micropore of infiltration face, are infiltration pore 3 in irregular shape.

The utility model soakaway trench is made infiltration face 1 and cavity face 2 by moulding the rubber blending foaming material, and its pipe wall thickness produces micropore by even foaming.

The utility model mainly is applied to buried form in the plants irrigations such as greenhouse by solar heat, orchard, lawn, greenbelt and sand prevention, sand control engineering.

Claims (2)

1, a kind of rubber blend foaming soakaway trench of moulding is the hollow lumen, and it is characterized in that: its tube wall from outward appearance to inner essence is followed successively by:

1. face seeps water: this infiltration face surface be covered with naked eyes invisible only can be under 10-20 times of magnifying glass can obvious clear demonstration countless micropores, these micropores are infiltration pore in irregular shape;

2. cavity face: this cavity face is the soakaway trench inner surface, this inner surface be covered with naked eyes invisible only can be under 10-20 times of magnifying glass can obvious clear demonstration countless micropores, these micropores are littler than the micropore of infiltration face, are infiltration pore in irregular shape.

To exosmosis, infiltration face was combined closely with the cavity face in described soakaway trench tube wall was served as reasons.

2, the rubber blend foaming soakaway trench of moulding according to claim 1, it is characterized in that: make infiltration face and cavity face by moulding the rubber blending foaming material, described pipe wall thickness produces micropore by even foaming.
