Embodiment 1

A kind of breeding method for encircleing pull-type tree bridge, (wherein Fig. 1,2,5,6,8,9 are structure diagram, are as shown in Fig. 1-9 Lines are seen clearly, and are omitted some structures, can Fig. 1-9 combine see), mainly include the following steps that：

First, tree bridge mold is made：It factually tramples and learns in tree bridge is cultivated, when trunk diameter reaches 8-10cm, set bridge knot Structure just can bear the gravity of pedestrian, therefore during making mold, trunk diameter is scheduled on 8-10cm.Structure and the trees of bridge are drawn according to arch Growth characteristics, tree bridge divide two large divisions, i.e. crane span structure and bridge floor.

(1) making of crane span structure mold：Crane span structure is made of inner structure and external structure, and inner structure is used to support external structure, outer knot The practical structures of structure, that is, bridge.

1. inner structure：As shown in Figure 1, inner structure is by two groups of pier columns 1, two horizontal beams 2 and two 3 groups of arched girders Into.And every group of pier column 1 is made of two pier columns 1.It is that bridge pier is stood that height according to pull-type tree bridge is encircleed, which subtracts 10cm, The height of column 1, with Φ 16mm reinforcement fabrications.The length of span, that is, horizontal beam 2 of bridge, with Φ 16cm reinforcement fabrications.Every level The both ends of beam 2 are respectively vertically welded with downwards a pier column 1, and the both sides that bridge is subtracted according to the width dimensions for encircleing pull-type tree bridge are each 10cm is as the width between two horizontal beams 2, with Φ 16mm reinforcement fabrications.Each rice is pressed as one using the length of horizontal beam 2 Node 1 a, node one 4 one, is allowed to weld together with welding method, forms horizontal beam crane span structure 5.According to the span of bridge Design the length and height of arch beam 3.According to beautiful, practical requirement, height, that is, spandrel peak to horizontal beam of arch beam 3 2 distance is advisable at 2 meters or more.It measures from the both ends of horizontal beam 2 to the arc length of the peak of arched girder 3, with Φ 16mm Reinforcement fabrication, and 2 both ends of horizontal beam are welded in, the width of the width same level beam 2 of two arched girders 3.2 every 1 meters of horizontal beam Node 1 connect vertically upward with arched girder 3, with Φ 16mm reinforcement fabrications, form arched girder column 6 and weld together.For Two arched girders 3 are fixed, it can with Φ 16mm reinforcing bars cross weld Φ 16mm reinforcing bars make on corresponding two arched girder columns 6 Be integrally formed, so far inner structure complete.

2. external structure：As shown in Fig. 2-5 (in figure, tree spanning degree is for 6 meters), above the horizontal beam 2 of inner structure Horizontal beam 2 is divided into two half blocks, then half block horizontal beam 2 is divided to for two parts in left and right, entire inner structure 4 totally by central point Point.By taking a portion as an example, to bridge central point since one end on horizontal beam 2, with every 1 meter, i.e., every meter of node 1 The moulding of upper weldering one ") " arc stent 7, with the reinforcement fabrication of Φ 8mm, round mouth towards horizontal beam 2, arc stent 7 it is upper Linear distance horizontal beam 2 is 10cm downward vertically at end, higher than horizontal beam 10cm.Other three parts require on an equal basis.It will with No. 12 iron wires The upper end of 2 side arc stent 7 of horizontal beam connects being aligned, i.e. horizontal beam line 8, that is, the beam of practical tree bridge.Two levels The width of beam line 8 is the width of practical tree bridge.The horizontal loop of a Φ 8-10cm is done at the beginning of each section horizontal beam line 8 9, for fixing arched girder line nursery stock 4 ', made of No. 12 iron wires.

At interval of one meter it is a node 2 14 on horizontal beam line 8, with No. 12 iron wires does one at node 2 14 and intersect and enclose Knot 15；Intersect loop knot 15 by iron wire B and iron wire C to be intersected；Iron wire B by horizontal linear section B 16, horizontal loop section 17 and upwards Vertical line section B 18 is sequentially connected composition；Iron wire C encloses section 20 and downward vertically straightway by horizontal linear section C 19, vertical stand 21 are sequentially connected composition；The vertical circle section 20 vertical with iron wire C's of horizontal loop section 17 of iron wire B intersects composition and intersects loop knot 15；It is horizontal Straightway B 16 and horizontal linear section C19 connect respectively with horizontal beam line 8；Consolidated between iron wire B and iron wire C with thin wire or cord Fixed connection；The equal 8-10cm of diameter of horizontal loop section 17 and vertical vertical circle section 20.

The central point of every horizontal beam line 8 makes the horizontal loop knot 1 of a Φ 8-10cm, this horizontal loop of No. 12 iron wires Knot 1 is intersected by two iron wire A, and every iron wire A is by horizontal linear section A 11, horizontal semi-circular section 12 and vertical straight upwards Line segment A 13 is sequentially connected composition, and the horizontal semi-circular section 12 of two iron wire A is opposite to form horizontal loop knot 1；Every iron wire A's Horizontal linear section A 11 connects with horizontal beam line 8；It is fixedly connected between two iron wire A with thin wire or cord.

Also by taking a part as an example, the straight line that lets droop in the upper end of one end arc stent 7 of horizontal beam 2 uses Φ to ground What 16mm reinforcing bars did pier column 1 widens column 22, by pier column 1 and is widened column 22 with Φ 12mm reinforcing bars, that is, crossbeam 23 and welded Together, one is made.Then according to the span of bridge, first one meter of node 2 14 since 8 end of horizontal beam line The straightway downward vertically 21 of the intersection loop knot 15 at place widens column 22 to nearest, and a lines are drawn with No. 12 iron wire G, and with level Beam line 8 widens one right angled triangle of formation of column 22, and iron wire G forms the first hypotenuse 24, the side of wide column 22 A length of 30-40cm, beginning, that is, lower end of this first hypotenuse 24 connect with the first hypotenuse nursery stock 3 '. The straightway downward vertically 21 of intersection loop knot 15 at second one meter of node 2 14 8 end of horizontal beam line is to nearest Widen column 22, draw a lines with No. 12 iron wires, and with horizontal beam line 8, widen column 22 and form a right angled triangle, this is straight The length of side that angle triangle widens column 22 is 60-80cm, and beginning, that is, lower end of this line connects with trees, later every meter of node 2 14 Bracing wire the rest may be inferred in proportion.The straightway downward vertically 21 of intersection loop knot 15 at the node 2 14 nearest from bridge center to Nearest widens column 22, and a line is drawn with iron wire H, makes iron wire H and horizontal beam line 8, widens one right angle trigonometry of formation of column 22 Shape, iron wire H-shaped is into the hypotenuse 25 nearest from bridge center.Other three branches require on an equal basis.

Outside Φ 8mm of 6 crosspoint of arched girder 3 and arched girder column, one horizontal columns 26 of long 10cm steel bar weldings, this is horizontal 26 outer end of column is connected together with No. 12 iron wires upward vertical line section B 18 corresponding with horizontal beam line 8, i.e. external structure connecting line, The bracing wire 27 of the namely practical pull-type tree bridge of arch.Since one end of arched girder 3, with reference to the position of horizontal columns 26 at bracing wire 27, 20-40cm is spaced to external application Φ 8mm, long 10cm steel bar weldings horizontal columns, then draws a line along the outer end of horizontal columns with No. 12 iron wires, The same arched girder of radian, i.e. arched girder line 28.Two upward 13 ends of vertical line section A of the horizontal loop knot 1 of central point pass through The bracing wire 27 for encircleing pull-type tree bridge is connected with arched girder line 28.The extended line of bracing wire 27 is in one circle Φ 8- of the winding of arched girder line 28 Vertically upward, this circle winds loop knot 29 to 10cm for arched girder line.Opposite side requires on an equal basis.From the bridge on two arched girder lines 28 Heart point starts to measure the point of 50cm to the left and right, and No. 12 iron wire D 30 are fixed on a little, so by two arched girder lines 28 totally 4 points Inwards obliquely, in the position higher than 28 central term of arched girder line, corresponding two iron wire D 30 make guiding iron wire D 30 afterwards Horizontal loop knot 2 31, for fixing arched girder line 28, i.e., the arched girder of practical tree bridge.It is complete by the entire external structure of procedure above Into.It should be noted that the iron wire of external structure is the route that trees are walked later, why the use of iron wire is complete in order to set bridge Into rear convenient for dismounting mold.

(2) making of bridge floor mold

Bridge floor is the difficult point set during bridge is cultivated, and only could innovatively be solved using the method for wound form plane bridge joint.Cause This, bridge floor is wider, and difficulty is bigger.

As shown in Fig. 6,7,8, start to be spaced 10cm stroke marks 32 in iron wire one end of two horizontal beam lines 8, then It is first corresponded on a horizontal beam 2 with No. 12 iron wire E 33 and is fixed at horizontal beam line mark 32, iron wire E 33 is upwards from water for traction Outside upwards, winds horizontal beam line 8 one and encloses, Φ 8-10cm are enclosed, until the mark 32 of horizontal beam line inwards at the mark 32 of flat-topped ridge line 8 Top, then in the horizontal direction at another 8 corresponding mark 32 of horizontal beam line along outside winding one upwards again inwards downwards Circle encloses Φ 8-10cm, is fixed still further below with horizontal beam 2, this line, that is, bridge floor connecting line 34.According to the span of bridge, and so on, Complete entire bridge floor connection.Iron wire E 33 winds loop knot 35 with the circle that horizontal beam line 8 is wound for bridge floor.

After the completion of bridge floor, because bridge railings is to be extended to complete by bridge floor trees, so on the basis of bridge floor, bridge railing is designed Bar, column are 1.2 meters high.Specific method is outside the joint after being completely wound at the both ends of first of the bridge floor connecting line 34 in bridge both ends Side is fixed respectively with No. 12 iron wire F, then iron wire F vertically upward 1.2 meters of eminences make a call to a turning loop knot 36 (for changing Direction and good-looking) after, it turns right-angled horizontal and is folded to bridge center position, and be pierced by upwards from next turning loop knot 36, this iron wire F Straightway, that is, bridge floor railing line 37；Other settings of bridge floor railing line 37 are that bridge floor side is opened from first of bridge floor connecting line 34 Begin, per one of bridge floor connecting line 34 of septum secundum, design bridge floor railing line 37 as stated above；The opposite side of bridge floor is bridge both ends second Road bridge floor connecting line 34 designs one of bridge floor railing line 37 as stated above, and other bridge floor railing lines 37 are every time again every one of bridge floor Connecting line 34 designs (as shown in Figure 9, in Fig. 9, tree spanning degree is for 2 meters) as stated above.

As shown in Figure 8, in figure, a, b, c, d represent the iron wire F of different location, and a is the iron wire F of end of the bridge, in 1.2 meters of eminences After making a call to a turning loop knot 36, turn right-angled horizontal and be folded to bridge center position, and worn from the turning loop knot 36 of next b iron wires F Go out upwards；B iron wires F turns right-angled horizontal and is folded to bridge center position after 1.2 meters of eminences make a call to a turning loop knot 36, and from next It is pierced by the turning loop knot 36 of a c iron wires F upwards；C iron wires F turns right-angled horizontal after 1.2 meters of eminences make a call to a turning loop knot 36 Bridge center position is folded to, and is pierced by upwards from the turning loop knot 36 of next d iron wires F, the rest may be inferred for other bridge floor railing lines Design.

A simple knot is made a call at all 37 to 1.2 meters of bridge floor railing lines, right-angled horizontal is turned and is folded to bridge center position, and under It being pierced by upwards in one turning knot, two, bridge center or so bridge floor railing line 37 passes through the turning knot 36 of other side upward, alternatively, Center is made a call to upward again after a horizontal loop knot.

2nd, transplanted seedling tree

(1) Tree Species Selection：Arbor is selected to implement the preferably selection happiness water tree that place is moist, has abundant water resources as plant seeds Kind, such as willow, Fast growth poplar, the seeds for selecting the branch such as elm, Chinese scholar tree, acacia length of other geological conditions, and pine and cypress can not With the seeds of also trunk marrow sky cannot be used, such as walnut, paulownia.

(2) calculating of nursery stock quantity：Nursery stock quantity nursery stock quantity needed for crane span structure, bridge floor needed for tree bridge forms.1. crane span structure Required nursery stock is determined more or less that crane span structure nursery stock requirement is calculated by every 1 meter of 1 sapling of span of bridge, separately by the span of bridge Outside, arched girder needs 4 arched girder line nursery stocks 4 ', and 1 ' the bridge both ends of fixation nursery stock that fixed function is played at tree bridge bridge pier position respectively need 2 Totally 4.2. nursery stock quantity needed for bridge floor is calculated by the span of bridge.Since end of the bridge, per 10cm one tree seedlings, in addition bridge both ends are each Increase by one, if the span of bridge is 6 meters, then nursery stock needed for bridge floor is 63.More than nursery stock quantity will have more 5% when designing, Prevent nursery stock dead, to fill in time.

(3) transplanted seedling tree is laid out

1. crane span structure nursery stock, at the both ends of bridge, each row is two rows of, totally four row crane span structure nursery stocks, often arranges and be spaced 10cm between crane span structure nursery stock Plant；As shown in Figure 8, it is corresponding with horizontal beam line 8, widen 22 side interval plant of column often row crane span structure nursery stock each, often arrange bridge Frame nursery stock is 8 beginning of horizontal beam line successively to first node 2 14 since the crane span structure nursery stock farthest from column 22 is widened Nursery stock 5 '；Arched girder line nursery stock 4 '；It is long according to bridge, from end of the bridge to bridge center, the first right angle trigonometry of every meter of formation of node 2 14 Shape bevel edge nursery stock 3 ', the rest may be inferred for other hypotenuse nursery stocks, until the hypotenuse seedling nearest from bridge center Wood 2 '；It is fixed nursery stock 1 ' later.

2. bridge floor nursery stock position is in the lower section of bridge, the position of both ends closely bridge pier, immediately below the center for avoiding bridge.In bridge Both sides, which are pressed, transplants one row of quantitative design or two rows, two-row spacing 30-50cm, and 5-10cm, bridge center underface are spaced between nursery stock For river, when such as considering that flood season rainwater is big, increase plant landform with cement stone.

(4) time and method are transplanted

Transplant the time：North China is in mid or late March, first to nursery stock cutting strunk, the dry height of crane span structure nursery stock, with each required The height at position determines, can (height for transplanting ground to bridge floor subtracts cutting strunk at 20cm) less than its height 20cm.Bridge floor seedling It wood 1 year more late than crane span structure nursery stock of the time of plant, i.e., is carried out after crane span structure moulding is basically completed, prevents from influencing each other, it is big according to nursery stock Small and bridge is high, if cutting strunk is same as above.Crane span structure position transplanted seedling tree is unsuitable too deep during plant, is grown with profit, routinely method for planting It carries out.Bridge floor nursery stock is depending on the land occupation condition of bridge, and the routinely method for planting not on natural river carries out, in natural river On, the depth of planting, and upper pressure stone, stone are increased, prevents trees washed away.Happiness water tree kind impregnates certain time in water It will not cause death.

3rd, bridge moulding order and method are set

Because the strength emphasis of tree bridge is on crane span structure, so the diameter of crane span structure trees is more than the diameter of bridge floor trees.Therefore, bridge Frame elder generation moulding 1 year, second year carries out bridge floor moulding again, and be staggered growth time in this way, avoids due to bridge floor trees quantity is big The influence brought.

(1) crane span structure type is made：It with the role respectively shared, is carried out according to designed mold, is spaced 3-5cm, it will with cord Trees and mold binding are primary, are allowed to fixed.Binding distance is shortened in corner.Check in 3-5 days is primary.

Bridge will be set using bridge central point as separation, Jiang Shuqiao is divided into symmetrical four part, by taking a quarter part as an example, often It arranges in crane span structure nursery stock：The nursery stock 5 ' of 8 beginning of horizontal beam line to first node 2 14 is cooked level first along crane span structure die horizontal circle 9 Moulding is enclosed, is passed through in bridge floor winds loop knot 35 along horizontal beam line 8 after the completion, at 8 first nodes 2 14 of horizontal beam line, edge Horizontal linear section B 16, horizontal loop section 17 and upward 18 trends of vertical line section B for intersecting loop knot 15 are pierced by, then up edge Bracing wire 27 is grown, then is grown up again after being wound on arched girder line nursery stock 4 ' along arched girder line winding loop knot 29.

Arched girder line nursery stock 4 ' grows along arched girder line 28, and the horizontal loop 9 for first passing through 8 beginning of horizontal beam line is raw upwards Long, until bridge central term, the arched girder line nursery stock to come with opposite growth is allowed to growth together using the method kinked, kinks length It spends for 100cm, then arched girder line nursery stock 4 ' sets head and grown obliquely inwards along iron wire D 30, two corresponding arched girder line seedlings Wood 4 ' knots by horizontal loop knot 2 31, grows then up.

First hypotenuse nursery stock 3 ' is along at 24 to the first nodes of the first hypotenuse 2 14, along handing over Straightway downward vertically 21, vertical vertical circle section 20 and the trends of horizontal linear section C 19 for pitching loop knot 15 are pierced by, then along horizontal beam Line 8 passes through in bridge floor winds loop knot 35, at 8 second nodes 2 14 of horizontal beam line, along the horizontal linear for intersecting loop knot 15 Section B 16, horizontal loop section 17 and 18 trend of vertical line section B is pierced by upwards, grow then up along bracing wire 27, then along arched girder Line winding loop knot 29 is grown up again after being wound on arched girder line nursery stock 4 '；Other hypotenuse nursery stocks class according to this It pushes away.

The hypotenuse nursery stock 2 ' nearest from bridge center, along the hypotenuse 25 nearest from bridge center to At the node 2 14 nearest from bridge center, straightway downward vertically 21, vertical vertical circle section 20 and the level that edge intersects loop knot 15 are straight The trends of line segment C 19 are pierced by, and are then passed through in bridge floor winds loop knot 35 along horizontal beam line 8, until bridge center, comes with bridge opposite Horizontal linear section A 11 of the hypotenuse nursery stock nearest from bridge center along horizontal loop knot 1, horizontal semi-circular section 12 And vertical line section A 13 carries out moulding upwards, forms a fixed point, is grown then up along bracing wire 27, then along arched girder line Winding loop knot 29 is grown up again after being wound on arched girder line nursery stock 4 '.

Fixed nursery stock 1 ' is abutted against oblique upper forward with crane span structure nursery stock in front one by one, and with cord and crane span structure nursery stock in front It is fixed, and with the fixation nursery stock of another row's crane span structure nursery stock of same end of the bridge, after intersecting among the front of two rows of crane span structure nursery stocks, then It is abutted against backward with arched girder line nursery stock 4 ', is allowed to form one, then prunes fixed nursery stock 1 ' and set head；Set bridge other 3/4ths Part carries out crane span structure moulding as stated above.

(2) bridge floor moulding：

Bridge floor nursery stock needed for bridge floor moulding in the lower section of bridge, is laid out according to planting of plants, according to principle nearby, determines Bridge floor nursery stock tree head is led to 8 bridge floor of horizontal beam line winding circle during binding by the correspondence bridge floor nursery stock of each bridge floor connecting line 34 Knot 35 after winding along bridge floor winding loop knot 35, moves towards to move ahead, until corresponding another 8 bridge floor of horizontal beam line along bridge floor connecting line 34 Loop knot 35 is wound, after winding, upper edge bridge floor railing line 37 is bent towards and carries out railing style, turning loop knot 36 is pressed to 1.2 meters of eminences It moves towards to knot, turns right-angled horizontal and be folded to bridge center position, and be pierced by and grow up from next turning loop knot 36；Herein In the process, bridge floor nursery stock is primary every 3-5cm cords and the binding of bridge floor mold, and for fixing, binding distance is shortened in corner. Bridge floor is clamped up and down with two blocks of 2cm solid woods when bridge floor seedling growth to diameter reaches 4-5cm, and plank width is bridge deck width 1/3rd, be centrally located, between two pieces of planks use Φ 8mm screw jam-packed, bridge floor nursery stock is made to broaden, adjacent bridge floor nursery stock is long Together, bridge floor flattens.After the completion of bridge floor nursery stock bridge railings moulding, bridge floor nursery stock and the adjoint place of bracing wire 27, with band rubber Electric wire is tightly wrapped with bracing wire 27, is allowed to grow together.

(3) it is dry to remove bridge floor growth

After bridge moulding is entirely set 3 years, when the winding horizontal beam line arboreal growth of bridge floor trees forms integrated together, Summer lies prostrate season, is entered at winding in bridge floor trees with saw and amputates 2 centimeters, and prescinds hair with sharp knife and be cut, and is allowed to smooth, then with disappearing Malicious mud is smeared sternly, is healed with profit, every 20 days, carries out once, doing by 3-4 secondary growths and being all removed as stated above.

Find what its truncation surface cannot still heal in removal process, illustrate nutrient delivery less than and cause, then gone with sharp knife Except part of thirsting, dew is shown in farm work, then applies disinfection mud, heals again.

When checking whether bridge floor trees and horizontal beam line trees form integrated, mainly see therebetween either with or without being formed Cross --- tree web.If not then the removal time is postponed, if though have not long flat or approximation usually, also to postpone removal Time illustrates to be not fully developed one therebetween, and internal structure is made in order completely not yet, and nutrition, moisture conveying channel are still Prematurity.

After dry remove is grown, bridge floor nursery stock stub, sandstone below tree bridge are removed in time, keep smooth under tree bridge.

4th, daily management and the prevention and control of plant diseases, pest control

Water and fertilizer management is the important component of daily management, and summer and autumn in spring, watering in 15-20 days is primary, and flood season regards drop Rain condition condition is suitably reduced, and is applied fertilizer in addition to base fertilizer, will also monthly ditching-fertilizing it is primary, generally apply outside composite fertilizer, bio-fertilizer or root Fertilizer, based on urea, meanwhile, every 20 days spray the foliar fertilizers such as potassium dihydrogen phosphate, Ye Mian Bao, accelerate arboreal growth, and enhance Tree vigo(u)r.

Generally the methods of preventing poisoning, take hoe, pull out, and fertilising is combined without using chemical herbicide during weeding, turn over warm and sunny soil Earth is ventilative with profit.

Trees pest and disease damage is in the majority with aphid, worm of floaing.Aphid nibbles tender leaf tree head, and worm of floaing gnaws leaf, stem, during prevention prevention be It is main, it based on the pesticides such as Rogor, phoxim, efficient chrysanthemum cyanogen fat, is used alternatingly, interval sprays once, during which according to disease for 15-20 days Insect pest a situation arises in time suit the medicine to the illness treat.It is more that trunk, branch formation wound are wiped out during rainy season moulding, prevents disease from invading, it can The disease preventions drugs such as carbendazim of interval spray in 15-20 days.To be carried out during spray by operation instruction, and ensure to spray it is even, with leaf Subject to when dripping with water.

5th, tree vigo(u)r and Disaster Prevention Measures are balanced

Tree bridge sets the moulding formed by tens of, and adjoint trees in moulding will be grown integrally, to prevent Long fast trees length it is faster, long slow trees grow slower, cause to occur to gobble small main phenomenon and occur, and refer to moulding Failure, therefore, balance tree vigo(u)r are most important.Specific method is to look at the upgrowth situation of each moulding tree.Such as judge a certain trees When growing speed, the growing state of the trees required on an equal basis and the growing state of coupled trees are seen.Take pinch a head, The method inhibition of cutting back, debranching grows the growing way of too fast trees.Meanwhile grow slow root and to strengthen water and fertilizer management, set head Dividing prevents from blocking influence daylighting by other branches and leaves, is such as found timely excision.Since moulding inhibits the normal growth of trees, institute It is many with coppice shoot, it wipes out in time.

In entirely tree bridge moulding, Propagating Tree head is divided into two parts, on the practical arched girder that a part is formed for crane span structure trees , another part is that the bridge that bridge floor topiary is formed is blocked on bar.According to tree bridge structural requirement, crane span structure trees rugosity is greater than The rugosity of bridge floor trees, according to the tree head height designed on practical arched girder, the tree that bridge is blocked on column is low, and control bridge is wanted in moulding The height that head is set on bar is blocked, while with the growth of growth time, setting all trees on bridge will be long integral, in ordinary circumstance Under, in entire moulding, set head height length it is fast, tree it is low grow slow, so using pinching a head, cutting back, go skill in moulding Method controls and keeps the tree head growth balance on practical arched girder on tree head and bridge railings, prevents the tree head on practical arched girder There is fast long, overgrowing.

Bridge is set in growth course, is to try every possible means to take measures to accelerate growth, after the completion of moulding, to control entire tree bridge Trees the speed of growth, using pinch a head, cutting back, debranching method carry out, make entirely to set bridge and seem that density is orderly, level divides It is bright, it is compact not random, reduce windage, the ingenious of bridge floor, railing, arched girder and connected structure can be can be clearly seen on bridge by walking. Above-mentioned trimming work at least carries out 2-3 times, while reduce the use of liquid manure every year, slows down the speed of growth, slows down tree pontic amount and increases Big speed extends tree bridge longevity.

In bridge moulding is set, since arboreal growth head is more, the scale of construction is big, to prevent blowing and raining, causes the crooked change of tree bridge Shape.With the steel wire rope of Φ 10mm, steel wire pull line, fixed entire pontic, general bridge side setting are set on the arched girder of inner structure Two bracing wires before major flood season arrival, will grow the first rule cutting back of too fast tree, reduce height, reduce the rolling to setting bridge Dynamic degree of convergence and damage.

6th, tree bridge mold is removed, access bridge is set

After the completion of bridge moulding is set, steel wire pull line is removed first.With hacksaw, spanner, cut greatly, the tools such as pliers remove mould Tool.During dismounting, inner structure reinforcing bar is first torn open, then tear the reinforcing bar iron wire of external structure open.Reinforcing bar iron wire is divided into cutting back convenient for taking with sawing, cutting It takes, then iron wire is extracted out from moulding with pliers, dismantle bridge floor clamping plate bolt with spanner, remove clamping plate.Nurse tree is paid attention to during work Skin prevents from damaging.

Access bridge is made with materials such as wood, planks with Shu Qiao to connect, tree bridge can pass through.
