For solving the problems of the technologies described above, the present invention has adopted following technical scheme: a kind of construction method of rocky slope plant greening and maintaining system is provided, and it comprises the steps:
(1) provides the water source;
(2) select and install water pump and filter;
(3) begin from filter, lay water-supply-pipe on the side slope surface;
(4) respectively behind filter and the peak of water-supply-pipe be installed into drain tap.
In the construction method of rocky slope plant greening and maintaining system of the present invention, water-supply-pipe is laid by the order of the person in charge, arm and hollow billet in the step (3).Fix every 1 " U " iron wire of 1～2 meter usefulness on the described hollow billet.
In the construction method of rocky slope plant greening and maintaining system of the present invention, described hollow billet is horizontally disposed, and the spacing of its water dropper increases along with the gradient and dwindles.Be specially on the side slope of 45 degree, the spacing of adjacent water dropper is 1 meter; Every increase by 15 degree of the gradient, 0.2 meter of the hypotelorism of water dropper; The water dropper flow is per hour 1 liter.The hollow billet spacing is a benchmark with 45 degree gradient side slopes, and the distance of adjacent hollow billet is 1 meter, every increase by 15 degree of the gradient, and the hollow billet spacing increases by 0.5 meter.
In the construction method of rocky slope plant greening and maintaining system of the present invention, provide the water source for building the pond by laying bricks or stones in the step (1), the size in pond is that the flow rate calculation according to the water source draws.The size in pond is calculated by 250 square metres of vegetation of 1 cube of water curing.
In the construction method of rocky slope plant greening and maintaining system of the present invention, water pump is water yield and a lift of selecting water pump according to the height of area of once irrigating and side slope in the step (3).Pump head should be more than or equal to the height of side slope, and water yield should be more than or equal to the summation of all water dropper flows.
The present invention compares with other maintenance process, has the following advantages: (1), safety: the methods that adopt artificial spray to water of the maintenance of greening side slope at present more, the people on the steep side slope of height in tow about the water pipe, move left and right goes out security incident easily.The present invention adopts the drip irrigation maintenance technology to need not the people and directly goes operation on side slope, so just can avoid occurring because of people's operation on side slope the hidden danger of accident.(2), water saving: can strictly control local irrigation quantity, reduce evaporation discharge, avoid rainwash and deep percolation by pipe network, have tangible water saving ability.(3), efficient: as to adopt the drip irrigation maintenance obviously to improve and water water speed and greening turf speed.Under the identical prerequisite of pump power, common 1 workman 1 day can only maintenance (watering) 5000 square metres, adopts 1 workman of drip irrigation system 1 day can maintenance (watering) 20000 square metres.Adopt the drip irrigation maintenance technology, the required moisture of plant growing can in time be met, and therefore afforesting turf speed shifts to an earlier date 30-60 days than general maintenance.(4), can not cause and wash away: artificial spray is watered easily soil layer to new spray and is caused and wash away loss, and drip irrigation is because water dropper is pressed close to the face of land, and the flow of water dropper is little, can not cause any souring to the soil layer of new spray.(5), evenly: be arranged in parallel because drip irrigation lines is equidistant, simultaneously the water yield of each water dropper much at one, so irrigation uniformity height generally reaches 80-90%, randomness and the inhomogeneities that can avoid artificial spray to water, so afforestation effect is in good order.(6), economize the fertile medicine of economizing: adopt drip irrigation can reduce air humidity, can avoid plant to water the damage that causes, thereby reduce the generation of damage by disease and insect because of spray.By in the pond, regularly adding fertilizer and agricultural chemicals, not only can reach the purpose of fertilising, laxative, also labor and material saving.
