Swan-neck, the one of nozzle of swan-neck setting corresponding with installation straight slot.
By using above-mentioned technical proposal, by the noise transmission to swan-neck of installing pipe, so as in swan-neck after
It resumes and broadcasts, since swan-neck madial wall is more bent, noise constantly encounters the tube wall of swan-neck, so as to which acoustic energy be made to be converted into heat
Can, and continuously decrease noise.
Further, the swan-neck madial wall is provided with noise reduction layer.
By using above-mentioned technical proposal, for noise reduction layer compared with swan-neck madial wall, erasure effect is more preferable, improves to reduce and make an uproar
The effect of sound.
Further, the bridge plate lower surface is provided with bridge pier, one end Yan Qiao of the swan-neck far from installation straight slot
Pier lateral wall is down-set.
By using above-mentioned technical proposal, the one end of swan-neck far from installation straight slot is extended at ground, so as to make to be subtracted
At weak noise transmission to ground.
Further, one end of the swan-neck lateral wall and close installation straight slot has been extended to installation straight slot direction
Taper collapses case.
By using above-mentioned technical proposal, noise can be reduced to swan-neck external communication, noise is made more to propagate to
In swan-neck, the effect for reducing noise is improved.
Further, the installing pipe includes what is connected in the supporing shell of " Contraband " font structure and with supporing shell sliding
Support cover board.
By using above-mentioned technical proposal, when needing replacing silencing cotton, support cover board can be removed, so that support plate
Side in open state, in order to be replaced to the silencing cotton in support plate.
Further, sliding convex block is provided in the support plate, the supporing shell madial wall is provided with convex for sliding
The slippage slot of block sliding.
By using above-mentioned technical proposal, when replacing silencing cotton, support plate can be slid out out of supporing shell, with
Preferably the silencing cotton in support plate is replaced.
Further, the supporing shell lateral wall is provided with the first limit to offset with barricade towards bridge plate direction side wall
Position plate, the support cover board lateral wall are provided with the second limiting plate to offset with barricade towards bridge plate direction side wall.
By using above-mentioned technical proposal, supporing shell and support cover board are inserted into when installing in straight slot, the first limiting plate,
Second limiting plate offsets with barricade, so as to which supporing shell be made to align with support cover board.
In conclusion the utility model has the advantages that：
1st, the slip mode of support plate and supporing shell is employed, consequently facilitating being carried out more to the silencing cotton in support plate
It changes；
2nd, swan-neck and the noise reduction layer on swan-neck madial wall are employed, the effect of noise is reduced so as to play better property
Fruit.

Embodiment：
A kind of environment-friendly type overpass, with reference to Fig. 1, the barricade 2 including bridge plate 1 and positioned at 1 both sides of bridge plate, barricade
2 height is 2-3 meters；1 lower surface of bridge plate is provided with bridge pier 11, with support bridge beam slab 1；Bridge plate 1, barricade 2 and bridge pier 11
It is made of armored concrete cast.
With reference to Fig. 2, each barricade 2 is disposed with several installation straight slots 21 along its length, installs straight slot 21
Cross section for rectangular configuration, the 21 madial wall fitting of installation straight slot is provided with installing pipe 3.
With reference to Fig. 3 and Fig. 4,3 madial wall of installing pipe is provided with several support plates 4；Whole support plates 4 are cross-linked in peace
The upper side wall of tubulature 3 and the lower wall of installing pipe 3；4 lateral wall of support plate is bonded with silencing cotton 5；The material of silencing cotton 5 is polyamine
Ester sponge or aluminium foil mineral wool, to reduce noise.
With reference to Fig. 3 and Fig. 4, installing pipe 3 includes supporing shell 31 and support cover board 32, and supporing shell 31 is in " Contraband " font knot
Structure；Cover board 32 is supported to be connected with the sliding of supporing shell 31,31 lateral wall of supporing shell is provided with T-slot 313 along its through-hole direction,
T-block 322 is provided on support cover board 32；After support cover board 32 is skidded off from 31 side of supporing shell, conveniently to silencing cotton 5 more
It changes.
With reference to Fig. 4, sliding convex block 41 is provided in support plate 4,31 madial wall of supporing shell is provided with slippage slot 312, sliding
Slot 312 is moved to slide for sliding convex block 41；Slippage slot 312 is set along 31 width direction of supporing shell, in order to by support plate 4 from branch
It is skidded off in support housing 31, easily facilitates and silencing cotton 5 is replaced.
With reference to Fig. 2 and Fig. 3,31 lateral wall of supporing shell is provided with the first limiting plate 311, the first limiting plate 311 and barricade 2
It offsets towards the side wall in 1 direction of bridge plate, in order to position position of the supporing shell 31 in installation straight slot 21；Support cover board 32
Lateral wall is provided with the second limiting plate 321, and the second limiting plate 321 and the side wall in barricade 2 towards 1 direction of bridge plate offset, so as to
In position of the positioning supporing shell 31 in installation straight slot 21, so that supporing shell 31 and support cover board 32 align.
With reference to Fig. 2, side wall of the barricade 2 away from 1 direction of bridge plate is fixedly installed supporting rack 22, supporting rack 22 by screw
It is upper that swan-neck 6 is fixedly installed by clip；6 one of nozzle of swan-neck is with installing 21 corresponding setting of straight slot；Noise passes through
When installing pipe 3 is propagated, the acoustic energy of a part of noise is converted into thermal energy；Another part noise enters in swan-neck 6, due to swan-neck
6 are more bent, and noise constantly abuts during propagation with 6 madial wall of swan-neck, thus noise during propagation by
Reduction gradually.The one end of swan-neck 6 far from installation straight slot 21 is along bridge pier 11（With reference to Fig. 1）Lateral wall extends downwardly setting, so that
Noise constantly weakens downwards；The part that swan-neck 6 is located at bridge pier 11 is fixed on by clip on bridge pier 11.
With reference to Fig. 2 and Fig. 5, the adherency of 6 madial wall of swan-neck is provided with noise reduction layer 61, and the material of noise reduction layer 61 is Polyurethane sea
Continuous or aluminium foil mineral wool, further to reduce noise.6 lateral wall of swan-neck and close to installation straight slot 21 one end to installation straight slot
21 directions have been extended taper and have collapsed case 62, to reduce the outside propagation of noise；
Operation principle is as follows：
When generating noise on bridge plate 1, noise is propagated to 2 direction of barricade, and is entered in installing pipe 3；Noise transmission is extremely
When at silencing cotton 5, the acoustic energy of noise is converted into thermal energy, so as to fulfill effective noise reduced on bridge plate 1.
After installing pipe 3, noise has substantially reduced noise；Noise by installing pipe 3 continues to propagate, and passes through successively
Taper collapses case 62 and swan-neck 6, since swan-neck 6 is in bending, and has noise reduction layer 61 in swan-neck 6, so as to very big
Noise is reduced in degree, substantially reduces the noise near overpass.
When needing replacing silencing cotton 5, installing pipe 3 is extracted out out of installation straight slot 21 first；Cover board 32 will be supported from branch
It is skidded off on support housing 31；Then, support plate 4 is slid out from 31 madial wall of supporing shell.The silencing cotton 5 of aging is removed, and
New silencing cotton 5 is pasted in support plate 4.
Then, support plate 4 is slipped on 31 madial wall of supporing shell, and support cover board 32 is mounted on support by sliding
On housing 31, to be assembled into installing pipe 3；Installing pipe 3 is inserted into installation straight slot 21, until the first limiting plate 311, second limits
Plate 321 offsets with barricade 2, realizes the replacement process of entire silencing cotton 5.
