With reference to the accompanying drawing and the principle of the present invention and structure is described in detail in embodiment.
As shown in Figure 1, specifically including that data acquisition equipment, more longitudinal directions the invention proposes a kind of intelligent civil grille
Rib and Duo Gen transverse direction rib, lateral rib intersects with lengthways of rod to be connected, wherein glass fibre is embedded in parts transversely rib
The second rib 2 is formed, glass fibre 11 is embedded in the lengthways of rod of part and fibre optical sensor group 12 forms the first rib 1, optical fiber
The first rib of epidermis 1 of 12 groups of outsourcings of sensor is completely cementing, and fibre optical sensor group 12 is connect with data acquisition equipment.The present invention
The intelligent civil grille proposed can be layed in the middle part or bottom of road deck 4 or base 5, be added with carrying out reinforcement to the layer
By force, and fibre optical sensor group be embedded in inside rib not directly bear traffic loading influence, without carrying out optical fiber at the construction field (site)
The work such as laying, fixed, improve and are laid with efficiency, while increasing glass fibre and Rut resistance and effect of prestressed can be improved.
In the present invention, the first rib 1 and the setting of 2 uniform intervals of the second rib guarantee that integral strength is uniform, make insertion first
The fibre optical sensor group 12 of rib 1 is arranged uniformly, it is ensured that the accuracy of data, and the spacing range between the first rib 1 exists
0.3m is between 0.8m, and the transverse width of the first rib 1 is in 1cm between 1.5cm, it is ensured that fibre optical sensor group 12 and glass fibers
Dimension 11 can be embedded in.The range of the thickness of intelligent civil grille proposed by the invention is in 2mm between 4mm, and breadth is 3 to 4
Between rice, lengths per roll of tape is mutually overlapped between 50 to 100 meters, and between every volume and every volume by fiber connector.
In specific implement, lateral rib is connected with lengthways of rod square crossing, make lateral rib and lengthways of rod it
Between form multiple square regions, netted rib 3 is equipped in square region, netted rib 3 is connected with lengthways of rod and transverse direction rib,
Entire mesh grille is constituted, wherein the grid gap of netted rib 3 assumes diamond in shape, the direction of the acute angle meaning of each diamond shape and vertical
Parallel to rib, the angular range of acute angle is between 45-60 °.By using network, pavement structure can be effectively improved and be expert at
Rigidity on vehicle direction achievees the effect that maximize under equivalent material cost.Simultaneously present invention may also apply to retaining wall, side slope,

In the present invention, fibre optical sensor group 12 includes the first sensor fibre 121 and the second sensor fibre 122, the first sensing
Optical fiber 121 and the second sensor fibre 122 are arranged side by side along longitudinal direction, and the first sensor fibre 121 is mainly used for detecting road traffic lotus
Carrier rail mark and axis weight, the second sensor fibre 122 mainly for detection of road structure health status.Also, the first sensor fibre
121 and second can mutually confirm between the data that can mutually monitor of sensor fibre 122, mutually compensate, optimizing detection effect.It passes
The concrete principle of photosensitive fibre is that stress caused by the load of road surface and road structure self-deformation will cause fibre strain, from
And make the optical path transmitted in optical fiber that frequency displacement occur, and then carry out road surface load according to the basic principle of distributed optical fiber sensing monitoring
The monitoring of size and its motion track.
In the particular embodiment, it is surrounded by and the first rib 1 outside the first sensor fibre 121 and the second sensor fibre 122
Cementing epidermis, wherein being fixedly connected between the second sensor fibre 122 and epidermis, and the epidermis and muscle of the second sensor fibre 122
Item bonds completely, makes 122 cooperative transformation of the second sensor fibre；The outer peripheral surface of first sensor fibre 121 it is smooth with epidermis slidably
Connection is mainly used for monitoring exterior vehicle load characteristics in application process, can weaken the influence of road structure deformation.
Simultaneously as without carrying out the work such as optical fiber laying, fixation at the construction field (site), and can have in the rib of optical fiber embedment grid
Protective grille is imitated not damaged by track and crack etc. during road is on active service.
As shown in Figure 2 and Figure 3, in specific application, the present invention can be applied to surface layer or the base of road respectively, right
In the relatively soft situation of roadbed (CBR < 5%) the case where, can by intelligent TGXG as base bottom, can to base into
Row reinforcement, while having stablizing effect to roadbed.The Intelligent road more for heavy vehicle, can be higher by content of glass fiber
Intelligent TGXG is layed in surface layer bottom, has Rut resistance and effect of prestressed to surface layer.
For base using the Intelligent road of intelligent TGXG, form of construction work is as follows:
After rolling, filling to roadbed, intelligent TGXG is used and is manually or mechanically layed in road bed, and carried out just
Step extends, overlaps and fixes, and should prevent direct wheel load from directly rolling the first rib containing fibre optical sensor group in construction, in base
Before layer is laid with, Ying Jinhang fibre optical sensor group validation checking.
Base's laying is carried out, pellet crushed rock base course or soil cement base is generally used, sufficiently rolls, make intelligent soil
There is good tessellation between work grid and base's soil body.
Carry out Construction of Asphalt Pavement.
Optical path and data acquisition equipment are connected with intelligent TGXG.
For surface layer using the Intelligent road of intelligent TGXG, form of construction work is as follows:
After to roadbed, base's filling construction, by intelligent TGXG using substrate surface is manually or mechanically layed in, go forward side by side
It goes and tentatively extends, overlaps and fix；It should prevent direct wheel load from directly rolling the first rib containing fibre optical sensor group in construction,
Before base is laid with, intelligent grid optical fiber validation checking should be carried out.
Carry out Construction of Asphalt Pavement.
Optical path and data acquisition equipment are connected with intelligent grid.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
