Abstract

The utility model discloses a sound barrier for a high speed railway, which relates to a railway facility. The sound barrier comprises columns which are respectively disposed at two sides of a rail at intervals, and a sound-proof barrier disposed between two adjacent columns. The sound-proof barrier is a multilayer composite structure. A sound-absorbing base plate, a prefabricated concrete plugboard and a panel are disposed in order from a side near the rail to a side away from the rail. The sound-absorbing base plate is a wood cement board with the internal part having a porous loose structure. The surface of one side of the sound-absorbing base plate, adjacent to the rail is wave-shaped, and the surface of the column is provided with a glass reinforced plastic anticorrosive coating. The sound barrier for a high speed railway is advantageous in that the performance of noise inhibition is good; weight is light; transport, installation and maintenance are convenient; construction cost can be reduced.

Description

A kind of high speed railway sound barrier
Technical field
The utility model relates to a kind of rail facility, relates in particular to a kind of high speed railway sound barrier.
Background technology
Improve the development of building along with railroad train speed; The noise that is produced during the high-speed railway operation is increasing to the interference of environment along the line; According to relevant protection rules with relate to standard; In high-speed railway circuit both sides sound barrier should be set, the sound that sends in the time of can making the motor-car operation is hindered in reaching resident's process, thereby reaches the effect of noise elimination noise reduction.The prefabricated light porous concrete wall of the many employings of existing sound barrier can reduce noise 5-10dB, and its noise suppression performance is lower; Crack resistance is poor, and fatigue resistance is poor, and own wt is big; Transportation and installation are all very inconvenient, and are connected weakness with roadbed, and work progress is complicated; Not easy-maintaining and replacing after the damage, construction cost is high.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of high speed railway sound barrier, has the favorable noise rejection, and in light weight, and transportation, easy to installation and maintenance helps reducining the construction costs.
The technical scheme of the utility model is: a kind of high speed railway sound barrier; Be included in the column that the track both sides are provided with at interval respectively and be mounted on the noise barrier between the adjacent upright posts; Said noise barrier is a multi-layer compound structure; Be followed successively by sound absorption base plate, precast concrete plate and panel from a side to a side away from track near track; Said sound absorption base plate is inner this cement board with porous loose structure, and the sound absorption base plate is near a side surface undulate of track, and the column surface is provided with the glass fiber reinforced plastic anticorrosive coat.
As preferably, said column is a H type shaped steel, and insert respectively in the corresponding side channel of adjacent two root posts at the two ends of noise barrier length direction, the bolt that is provided with through longitudinal separation on the column.
As preferably, said noise barrier top is provided with buckle along its length direction, and buckle is fixedly connected with column, and buckle adopts reinforcement Ya Like material to process.
The beneficial effect of the utility model is: the mode that the utility model adopts noise barrier to be installed between H type shaped steel column is processed sound barrier, the noise barrier light weight, and transportation and installation are all very convenient, have reduced construction cost.Noise barrier is a sandwich construction, and wherein, the sound absorption base plate is inner this cement board with porous loose structure; Acoustically effective is good, and the sound absorption base plate can let and directly be mapped to the not directly reflection of noise on the plate face near a side surface undulate of track; Increased the decay of noise, promoted the sound insulation value of the utility model, the rigidity of precast concrete plate is big; Be out of shape for a short time, have good anti-fatigue performance and endurance quality, and can further improve the soundproof effect of the utility model; Let this use is novel to have a favorable noise rejection, sound insulation factor (RW) is more than or equal to 30dB.Glass fiber reinforced plastic is good anticorrosive material, and atmosphere, water and multiple acid, alkali, salt and multiple organic solvent are all had good resistivity, has prolonged the application life of the utility model, and only needs at column external coating glass fiber reinforced plastic, and manufacture craft is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional view of the utility model.
The specific embodiment
As a kind of embodiment of the utility model, as depicted in figs. 1 and 2, a kind of high speed railway sound barrier; Be included in the column 1 that the track both sides are provided with at interval respectively and be mounted on the noise barrier 2 between the adjacent upright posts 1; In the present embodiment, as preferably, said column 1 is a H type shaped steel; Insert respectively in the side channel of adjacent two root posts, 1 correspondence at the two ends of noise barrier 2 length directions, fixing through the bolt 3 that longitudinal separation on the column 1 is provided with; Column 1 surface is provided with the glass fiber reinforced plastic anticorrosive coat.Glass fiber reinforced plastic is good anticorrosive material; Atmosphere, water and multiple acid, alkali, salt and multiple organic solvent are all had good resistivity, prolonged the application life of the utility model, and it only needs at column 1 external coating glass fiber reinforced plastic; Manufacture craft is simple, and is very practical.
Said noise barrier 2 is a multi-layer compound structure; Be followed successively by sound absorption base plate 21, precast concrete plate 22 and panel 23 from a side to a side away from track near track; Said sound absorption base plate 21 is inner this cement board with porous loose structure, and sound absorption base plate 21 is near a side surface undulate of track, and corrugated surface can let and directly be mapped to the not directly reflection of noise on the plate face; Increase the decay of noise, promoted the sound insulation value of the utility model.The rigidity of precast concrete plate 22 is big, is out of shape for a short time, has good anti-fatigue performance and endurance quality, and can further improve the soundproof effect of the utility model.In the present embodiment, as preferably, said noise barrier 2 tops are provided with buckle 4 along its length direction, and buckle 4 is fixedly connected with column 1, and as preferably, buckle 4 adopts reinforcement Ya Like materials to process.
