Abstract

The utility model relates to a paving brick, in particular to a heavy-duty high-speed paving brick and pavement structure which is low-carbon and environment-friendly, and can prolong the service life of a pavement. The heavy-duty high-speed paving brick and pavement structure is provided with a brick body, and is characterized in that the brick body is polygonal, at least two mounting grooves are arranged in the bottom surface of the brick body, a cement concrete cushion layer and a paving brick laying layer are also arranged on the bottom surface of the brick body, the paving brick laying layer is formed by paving more than two paving bricks, waterproof isolation strips are respectively arranged between the more than two paving bricks, the brick body of the paving brick is in six-edged shape, five grooves parallel to one another are arranged in the bottom surface of the brick body, more than two grooves parallel to one another are arranged in the upper surface of the cement concrete cushion layer, and the paving brick laying layer and the cement concrete cushion layer are fixed into a whole via bonding and inlaying the grooves and cement mortar. Compared with the prior art, the heavy-duty high-speed paving brick and pavement structure has the obvious advantages of heavy duty resistance, simple and convenient construction, low construction cost, short construction period and the like.

Description

Heavy duty expressway face brick and road structure

Technical field

The utility model relates to a kind of pavior brick, the heavily loaded expressway face brick and the road structure of specifically a kind of low-carbon environment-friendly, raising service life of road surface.

Background technology

As everyone knows, the express highway pavement structure types is generally flexible pavement or cement concrete pavement, and wherein the former is a flexible pavement, and the latter is the rigid pavement.The advantage that cement concrete pavement has the price height, not just influenced by temperature, intensity is high, but constuction joint is many, the driving comfort level is poor.In order to solve the problem that cement pavement exists, present stage the express highway pavement structure types adopt flexible pavement more, its advantage comprises that planeness is high, drive a vehicle comfortable, noise is little; Convenient and quick construction, maintenance is fast, but exists shortcoming such as ageing of asphalt fast simultaneously; Contaminated air and water source, life cycle is short, and summer, caloric receptivity caused surface temperature too high greatly; Influence the tire running safety, high temperature season is easy to generate rut, the shortcoming of low temperature easy of crack; And along with the growth of service time, flexible pavement can take place also that pitch particle comes off, embrittlement, problems of crack.

Present stage, pavior brick was used for the laying in one skilled in the art path, city more, and pavior brick generally adopts concrete to process, and had the intensity height, cost is low; Can realize advantages such as decorative pattern, in process of deployment, the arrangement of polylith pavior brick is laid on the roadbed according to construction requirement; Use the bonding of cement mortar realization pavior brick to inlay in case of necessity,, therefore can adapt to the laying in various zones to greatest extent because every brick body of pavior brick is less; Do not need special big machinery during construction; Have that cost is low, the construction period is short, the high significant advantage of intensity, but present stage the path surface evenness laid of pavior brick lower, and bonding to inlay firm degree poor; When heavy-load automobile through out-of-date, tend to take place phenomenons such as road surface breakage, pavior brick be loosening.

Summary of the invention

The utility model proposes a kind of rational in infrastructure, easy construction to the deficiency that exists in the prior art, can effectively save construction cost, and intensity is high, anti-heavy duty, is suitable for heavily loaded expressway face brick and road structure that express highway pavement is laid.

The utility model can reach through following measure:

A kind of heavily loaded expressway face brick is provided with the brick body, it is characterized in that the brick body is a polygon, and brick body bottom surface is provided with at least four grooves.

A kind of heavily loaded high speed road structure; Be provided with coagulating cement soil padding and pavior brick and lay layer; It is characterized in that said pavior brick laying layer is formed by the laying of at least two block road bricks; Be provided with the waterproof isolating bar between two above pavior bricks, the brick body of said pavior brick is the hexagonal prismatic, and brick body bottom surface is provided with four grooves that are parallel to each other; Said coagulating cement soil padding upper surface is provided with the groove that is parallel to each other more than many, and pavior brick is laid layer and coagulating cement soil padding and inlayed through groove and cement mortar bonding and be fixed as one.

The utility model compared with prior art because every block road brick all can bear 10 tons of horizontal thrusts, can satisfy 5 full weights load vehicle ' below 100 tons; It is damaged to guarantee effectively that pavior brick is laid layer, and not loosening, life cycle is long; Degree of resistance to wearing 80 years, anti-aging 100 years.

Description of drawings:

Accompanying drawing 1 is the structural representation of pavior brick in the utility model.

Accompanying drawing 2 is structural representations that pavior brick is laid layer in the utility model.

Accompanying drawing 3 is structural representations of road structure in the utility model.

Reference numeral: coagulating cement soil padding 1, groove 2, pavior brick 3, waterproof isolating bar 4, pavior brick are laid layer 5, cement mortar 6.

The specific embodiment:

With implementing the utility model is done further explanation below in conjunction with accompanying drawing.

The utility model is at first laid cement concrete bed course 1 on roadbed when implementing, construction requirement soil layer compacted density bearing capacity is greater than 0.15MPa; After top used the stiff cement concrete of C15 to lay the height of 500mm, the compacting of vibrating did not have the shrinkage joint construction method, is routed to then on the roadbed; Be provided with each interval 70mm, parallel each other at coagulating cement soil padding 1 upper surface, wide 50mm, the groove 2 of dark 6mm; Be used to increase the bond area of cement mortar 6, the pavior brick that realization is made up of pavior brick 3 is laid firmly inlaying of layer 5 and coagulating cement soil padding 1, and pavior brick 3 brick bodies are the hexagonal prismatic; Pavior brick 3 bottom surfaces are provided with four grooves that parallel 2; Longitudinal seam is cut into oblique, and stagger half of length of every brick body inlayed, the length of butting with effective minimizing; Paste EPDM waterproof isolating bar 4 two adjacent pavior brick 3 sides in the process of laying; Through waterproof isolating bar 4 is set, can effectively prevents heat expansion in summer, winter problem, and can increase surface evenness, improve pavement quality because of the ponding frost heave.

The utility model compared with prior art can overcome existing flexible pavement life cycle weak point, and summer, the road surface influenced deficiencies such as vehicle driving safety, polluted source air after melting, and has significant advantages such as anti-heavy duty, life cycle length.
