Abstract

The invention provides a seashore solonchak greening and water saving method. The method comprises the following steps of: (1) firstly, determining the arrangement position of an impounding reservoir after a green belt is fixed, particularly arranging the impounding reservoir underground for not occupying surface land of the green belt; (2) connecting roadside rainwater wells and the impounding reservoir together through pipelines for collecting rainfall; and (3) arranging a water pump, connecting the water pump with a water outlet pipe, wherein the lower end of the water outlet pipe is arranged at the bottom of the impounding reservoir, the water outlet pipe is provided with a plurality of valves on the ground for connecting sprinkling irrigation facilities conveniently in use. The method has the beneficial effects of reducing coastal greening cost and tap water consumption and saving fresh water resources in coastal areas.

Description

Marine solonchak greening water-saving method

Technical field

The invention belongs to the afforestation field, especially relate to a kind of marine solonchak greening water-saving method.

Background technology

China Bohai Rim annual rainfall seldom only about 500mm, can not satisfy the needs of coastal area virescence maintenance.Therefore, the annual a large amount of manually-injected tap water of use that needs.Simultaneously, the water that the virescence maintenance in coastal beach area need water than landlocked greening is more, and expense is more.The coastal area is after rainy season precipitation, and major part has all run off, and is a kind of great waste, so the coastal area can be by collecting the consumption that natural rainfall reduces tap water in the greening, this is a continuable water-saving method.

Summary of the invention

The purpose of this invention is to provide a kind of marine solonchak greening water-saving method, thereby reduce coastal area greening cost, conserve water resource.

Technology contents of the present invention: may further comprise the steps:

A, at first determine the putting position of reservoir after determining in the greenery patches, in order not take soil, the face of land, greenery patches, reservoir is arranged on underground;

B, the catch-basin that the road next door is provided with are connected by pipeline with reservoir, are used for collecting precipitation;

C, water pump is set, water pump is connected with outlet pipe, and the outlet pipe lower end is positioned at the reservoir bottom, and outlet pipe just is provided with a plurality of valves on the ground, connects equipment of sprinkler irrigation during convenient the use.

In said method, described reservoir is apart from more than edge, the greenery patches 2m.Because the adjacent highway in greenery patches, reservoir is near excessively apart from highway, can impact roadbed, and the vibrations that the while car causes also can be shortened the application life of reservoir.

Preferably, described reservoir cross section is trapezoidal, comprises Chi Gai, pool wall and base, and pool wall and base are concrete structure.

Particularly, when reservoir cross section when being trapezoidal, it is 0.2m that wide 2m thickness is covered in described pond, and pool wall thickness is 0.1m, and the wide 2m thickness of base is 0.2m, the wide 1.5m of reservoir opening, pond bottom width 1.2m, dark 1.5m.

Wherein, be provided with the reinforcing bar of colligation in the described base, adjacent two reinforcing bar binding nodal pitches are 0.5m.The reservoir base pressure is bigger, adds reinforcing bar in the concrete and can make reservoir more firm.

Wherein, described reservoir is positioned at below the 0.4m of ground.Reservoir is near excessively apart from the face of land, can influence the growth of reservoir top nursery stock.

Wherein, outlet pipe and water pump all are located at the side of covering, pond, convenient for maintaining.

Preferably, the spacing of adjacent two valves is 40m on the ground.Effect but also can reducing the construction costs not only can guarantee to spray.

Beneficial effect of the present invention: the first, natural rainfall is stored, use to the season of little precipitation, can reduce the use amount of tap water in a large number, can save the freshwater resources of coastal area; The second, reservoir is located at the below, greenery patches, and is easy to use, do not need extra occupied ground; The 3rd, this technology is convenient and easy, is suitable for promoting the use of; The 4th, this method cost is low, once drops into and can use for a long time, greatly reduces strand greening cost.

Among the figure: 1, reservoir, 2, catch-basin, 3, pipeline, 4, highway, 5, the road kerbstone, 6, water pump, 7, outlet pipe, 8, valve, 9, the reservoir opening, 10, greenery patches, 11, Chi Gai, 12, pool wall, 13, reservoir base, 14, at the bottom of the pond, 15, the laid reinforcement binding node, 16, soil, 17, ground, 18, standing groove.

The specific embodiment

Specify below in conjunction with accompanying drawing:

As shown in Figure 1, choose greenery patches 10 after, determine that according to greenery patches 10 peripheral shape reservoir 1 builds the position.Excavation tunnel, back is determined in the position, the dark 2.1m in tunnel, and wide 2.5m is apart from greenery patches 10 edge 2m.

As Fig. 2, Fig. 3, shown in Figure 4, build the reservoir base 13 of steel concrete in the bottom, tunnel, reservoir base 13 wide 2m, thick 0.2m.Laid reinforcement binding node 15 spacings are 0.5m in the reservoir base 13.After reservoir base 13 constructs, with concreting pool wall 12, pool wall 12 thick 0.1m, 14 wide 1.2m at the bottom of the pond, reservoir opening 9 wide 1.5m, reservoir 1 dark 1.5m.At reservoir 1 loam cake upper

storage reservoir lid

11,11 wide 2m, thick 0.2m are covered in the pond.

As shown in Figure 5, reserve connector above pool wall 12, the catch-basin 2 on highway 4 next doors is connected by pipeline 3 with connector on the pool wall 12.

As Fig. 6, shown in Figure 7, above reservoir 1, dig the standing groove 18 of a long 1m of the wide 0.5m of dark 0.3m, be used to place water pump 6, outlet pipe 7 is laid on the pond and covers 11 tops and be connected with water pump 6, outlet pipe 7 one ends reach at the bottom of the pond 14, the part mounted valve 8 that outlet pipe 7 elevates above the soil, the spacing of adjacent two valves 8 are 40m.The earthen backfill of sap.The thickness of necromancer is 0.4m on the lid 11 of pond, can guarantee the normal growth of nursery stock.

Principle: when raining, the rainwater on the highway 4 flows in the catch-basin 2, and the water in the catch-basin 2 flows in the reservoir 1 again and stores.When needing, extract, by the equipment of sprinkler irrigation of installing on the valve 8 greenery patches 10 is irrigated again by water pump 6 with the water in the reservoir 1.

More than an embodiment of invention is had been described in detail, but described content only is preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to the present patent application scope change and improve etc., all should still belong within the patent covering scope of the present invention.
