Abstract
The invention discloses a nondestructive measurement method for tree deformation. The measurement method utilizes a spring steel wire hoop sleeve method, namely a fixed cushion block which is provided with a deformation sensor is threaded on a steel wire; one end of the steel wire is coupled with a spring and the other end of the steel wire is provided with a hook; the spring steel wire surrounds a trunk for one circle and the hook is hung on the spring; the spring steel wire surrounds the truck for two circles up and down respectively; and the deformation sensor is mounted on the fixed cushion block which is threaded on the steel wire. The nondestructive measurement method for the tree deformation solves the problem of the prior art that normal cell tissues of trees are easily damaged by the measurement of the tree deformation and has the advantages of simple design and reasonable structure; and the nondestructive measurement method for the tree deformation can ensure that the stress deformation of the trees is conveniently and accurately measured under the precondition that the trees are not damaged.
Description
Technical field
The present invention relates to protection of trees technical field, specifically belong to nondestructive measurement method for tree deformation.
Background technology
How realizing the convenience to trees stress deformation, effective non-destructive measuring method, is the gordian technique of the anti-drifting snow hazard ability of research trees.But up to now; the two ends of sensor are followed closely in trees with nail by various countries; this mode easily damages the cell tissue of formation layer in trunk and xylem, therefore, should not adopt for needing the above-mentioned measuring method that damages of the ancient and well-known trees of special protection.
Content of the present invention
The object of the invention is to propose a kind of nondestructive measurement method for tree deformation, solve prior art measures easily damage trees normal cell tissue problem to tree deformation, simplicity of design, rational in infrastructure, can guarantee under the prerequisite not damaging trees the convenience of trees stress deformation amount, Measurement accuracy.
The technical solution used in the present invention is as follows:
Nondestructive measurement method for tree deformation, this described measuring method, adopt spring steel wire cuff method, be about to be through steel wire for the fixing cushion block installing deformation-sensor, steel wire one end has spring, and the other end has hook, steel wire encloses around trunk one, be hung on spring, steel wire is upper and lower two circles around trunk, and deformation-sensor is installed on the fixing cushion block that is through on steel wire.
Described fixing cushion block is nylon cushion block, and nylon cushion block lower end is provided with rubber blanket.
Described fixing cushion block corner is provided with fine steel needle, and fine steel needle length is optional, makes it only to thrust the outer dead cell part of bark, play the effect stoping cushion block to slide.
Described fixing cushion block is provided with deformation-sensor mounting hole.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention designs and adopts elastic wire cuff method, and be upper and lower two circles by spring steel wire around trunk, displacement transducer is installed on fixing cushion block.This mode can not produce damage to trees, measures accurately tree deformation.Simultaneously easy to use for irregular tree dry measure.
Accompanying drawing explanation
Fig. 1 is spring steel wire cuff apparatus structure schematic diagram of the present invention;
Fig. 2 is that spring steel wire cuff device of the present invention and deformation-sensor are installed on tree structure schematic diagram.
Embodiment
See accompanying drawing, nondestructive measurement method for tree deformation, this measuring method, adopt elastic wire cuff method, nylon cushion block 1 is through on steel wire 2, steel wire 2 one end has spring 3, steel wire 2 encloses around tree body 4 one, the steel wire of steel wire 2 other end additional length is cut off during in-site installation, be crafted into again and hook-shapedly connect with other end spring 3, upper and lower two two ends of measured tree body 4 are equipped with spring steel wire coil, and nylon cushion block is provided with deformation-sensor 5 and installs inner bolt hole 8, are arranged on by deformation-sensor 5 on nylon cushion block 1 and just can carry out harmless or micro-loss measurement to trees.Nylon cushion block 1 lower end is provided with rubber blanket 6, and rubber blanket 6 is between nylon cushion block 1 and tree body 4.Nylon cushion block 4 four jiaos there is fine steel needle 7, its length is optional can be needed to select according to actual conditions, short fine steel needle can be selected for rare ancient tree, make it only to thrust the outer dead cell part of bark, play the effect stoping nylon cushion block 1 to slide, cuff spring steel wire coil can prevent nylon cushion block from coming off.Usually, the bark of ancient tree is thicker, and the method can realize the effect of nondestructive measurement, not only convenient but also reliable.
Claims (1)
