The installation method of the trunk runoff gathering-device for city trees and shrubs in the present embodiment, comprises the following steps:
(1) measure the girth of trunk distance ground setting height, the first silica gel strip 3 that intercepted length is equal with girth, intercepts the second silica gel strip 2 of corresponding length;
(2) use rubber plug card punch, the first silica gel strip 3 punches;
(3) the first silica gel strip 3 is centered around the position of trunk distance ground setting height, cable strap 4 is used to fix the latter half of the first silica gel strip 3, again the two ends of the first silica gel strip 3 are used adhesive bonding, use glass cement to seal between the first silica gel strip 3 and trunk, as in Figure 3-5;
(4) adhesive is smeared in the latter half of the second silica gel strip 2, the latter half of second silica gel strip 2 is centered around the first half of the first silica gel strip 3, cable strap 4 is used to fix the latter half of the second silica gel strip 2, again the two ends of the second silica gel strip 2 are used adhesive bonding, as in Figure 3-5;
(5) one end of aqueduct 5 is penetrated in the hole 7 of the first silica gel strip 3;
(6) use rubber plug card punch, gathering-device 6 punches, the other end of aqueduct 5 is penetrated in the hole of gathering-device 6.
Setting height is 500mm, can adjust according to trunk growth conditions within the scope of upper and lower 100mm.
Intercept the second silica gel strip of corresponding length in step (1), the method calculating corresponding length is:
Second silica gel strip length=3.14* (the first silica gel strip length+2mm),
Wherein the first silica gel strip length equals trunk distance setting height place, ground girth.
In another embodiment, selects the diameter of a cross-section of a tree trunk 1.3 meters above the ground to be 156mm perfume camphor tree in Shanghai Communications University's agricultural and biological institute southern side, measuring it overhead the diameter at 500mm place is 162mm and girth is 509mm, and namely setting height is 500mm.
First intercept the wide 20mm of being, height is 20mm, length is first silica gel strip 3 of 509mm, the hole 7 that rubber plug card punch drill diameter is 9mm is being used apart from 250mm place, its one end, be 9mm by external diameter, internal diameter is that silica gel hose one end of 7mm is through hole 7, and it is concordant with it, then with glass cement sealing, as aqueduct 5; First silica gel strip 3 is centered around trunk overhead 500mm place, uses 4 cable straps 4 to join end to end and to be fixed in first silica gel strip 3 the latter half, and seal the gap between the first silica gel strip and trunk with glass cement;
Because every bar cable strap length is fixing 200mm, so adjustment quantity can be carried out according to trunk girth.Such as trunk girth 600mm, that with regard to needs 4 * 200mm=800mm join end to end carry out enclosing fixing.Other materials, such as iron wire, tie are also operable.
Intercepting width is 10mm, is highly the second silica gel strip 2 that 30mm, length are 635mm, adhesive is smeared within the scope of its latter half 10mm, be centered around outside the first silica gel strip 3 by the first half 10mm place, join end to end with 5 cable straps 4 and be fixed, and adhesive bonding is used at two ends, use glass cement closes the gap between the first silica gel strip 3 and the second silica gel strip 2 simultaneously; First silica gel strip 3, second silica gel strip 2 and trunk enclose and form the wide 20mm of being in bottom, height is the entrapping tank 8 of 20mm; Finally on dust-collecting bucket 6 bung that volume is 20L, use rubber plug card punch to beat the hole that diameter is 9mm, the other end of aqueduct 5 is penetrated in hole.
The trunk runoff gathering-device of the present embodiment can operate in 1 hour, and is easy to remove.During rainfall, first trunk runoff enters the first silica gel strip 3, second silica gel strip 2 and encloses in the entrapping tank 8 of formation with trunk, then flows into dust-collecting bucket 6 via hole 7 along aqueduct 5.
After measured, be less than or equal under storm intensity, the trunk runoff gathering-device of the present embodiment is being metalled run out, drainage, effectively, accurately can collect trunk runoff, meanwhile, because it is succinctly attractive in appearance, having and promote city trees and shrubs scenic beauty function.
In yet another embodiment, in Shanghai Communications University, agricultural selects the diameter of a cross-section of a tree trunk 1.3 meters above the ground to be 324mm plane tree with biological institute southern side, and measuring it overhead the diameter at 500mm place is 307mm and girth is 964mm.
First silica gel strip 3 of the 964mm that first intercepts that width is 20mm, highly to be 20mm, length be, the hole 7 that rubber plug card punch drill diameter is 9mm is being used apart from 480mm place, its one end, be 9mm by external diameter, internal diameter is that silica gel hose one end of 7mm is through hole 7, and it is concordant with it, then with glass cement sealing, as aqueduct 5; First silica gel strip 3 is centered around trunk overhead 500mm place, uses 7 cable straps 4 to join end to end and to be fixed in first silica gel strip 3 the latter half, and with the gap between glass cement sealed silicon adhesive tape and trunk.
Intercepting width is 10mm, is highly the second silica gel strip 2 that 30mm, length are 1090mm, adhesive is smeared within the scope of its latter half 10mm, be centered around outside the first silica gel strip 3 by the first half 10mm place, join end to end with 8 cable straps and be fixed, and adhesive bonding is used at two ends, use glass cement to close gap between the first silica gel strip 3 and the second silica gel strip 2 simultaneously.
First silica gel strip 3, second silica gel strip 2 and trunk enclose and form bottom width and be 20mm, highly be the entrapping tank 8 of 20mm.
Be on dust-collecting bucket 6 bung of 20 liters at volume, use rubber plug card punch to beat the hole that diameter is 9mm, aqueduct 5 other end is penetrated wherein.
Trunk runoff gathering-device for city trees and shrubs provided by the invention and installation method, adopt silica gel strip to form entrapping tank, even if when rainfall is larger, trunk runoff can be collected completely, nothing is leaked, phenomenon of metalling run out occurs, and improves the degree of accuracy that city trees and shrubs trunk runoff is collected; Adopt silica gel strip to form entrapping tank, little on arboreal growth impact, structure is simple and be easy to remove, can be cost-saving.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that the ordinary skill of this area just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
