Abstract

The utility model discloses a cement pavement structure which is formed by joining a plurality of cement concrete plates, wherein a joint seam is preserved between every two adjacent cement concrete plates; and an infill is arranged inside the joint seam. The cement pavement structure further comprises an elastic concrete layer, wherein the elastic concrete layer is arranged between two adjacent cement concrete plates in an embedded manner and the upper end surface is externally exposed; and the elastic concrete layer is positioned above the joint seam and is wider than the joint seam. Preferably, a cover plate for covering the joint seam is arranged at the bottom of the elastic concrete layer. The cement pavement structure has the advantages that firstly, water is unlikely to enter the joint seam, so that the cement concrete plates are unlikely to deform and cave in as too much water enters the roadbed below the cement concrete plates; secondly, the elastic concrete layer is high in strength, good in impact resistance, good in toughness, unlikely to age and solider in structure at the joint seam, and the edges of the cement concrete plates are unlikely to break under the action of automobile tires; thirdly, the elastic concrete plate has good deformation property, and can effectively handle the change of gaps among the cement concrete plates caused by expansion with heat and contract with cold or external force action; and fourthly, the construction process is simple, the maintaining time is short, and only one to two hours are taken, so that the construction period is shortened.

Description

The cement pavement structure

Technical field

The utility model relates to a kind of road structure, especially a kind of cement pavement structure.

Background technology

Existing cement pavement structure is spliced by some cement concrete plates, be provided with splicing seams between adjacent two cement concrete plates, usually being used for concrete Pavement mosaic crack structure is the pitch cementation of fissures, adopts reinforcing bar to connect between the concrete plate, by the mode of occupation in process always, the service property (quality) time limit is shorter, water proofing property is poor, keeps in repair the engineering time by original structure long, and quality can't guarantee, large on the traffic safety impact, cost is high.Construction technology and material were by following several respects defective in the past:

1, connect with reinforcing bar between the concrete plate, construction inconvenience, and in seam, in case water inlet, reinforcing bar and the reaction of aquatic rust produce and expand, and destroy the plate quality of connection, and the reinforcing bar connection causes interplate stroke littlely, affects the life-span.

2, splicing seams place cementation of fissures pitch, under exposing to the sun and rain, the time has been grown, and is easily aging.

3, asphalt joint is flexible, there is no intensity, and easily concrete plate corner angle are broken under the vehicle tyre effect.

4, adopt the original structure maintenance, technique is more complicated, and the concrete curing time is long, and long construction period is of poor quality, and is large on the traffic safety impact.

Therefore be necessary existing cement pavement structure is improved.

Summary of the invention

The purpose of this utility model is a kind of cement pavement structure that designs for the deficiency that solves above-mentioned technology, is difficult for water inlet, long service life, construction technology in this cement pavement structures to form seam more simple.

The cement pavement structure that the utility model is designed, be spliced by some cement concrete plates, be provided with splicing seams between adjacent two cement concrete plates, be provided with obturator in splicing seams, also comprise embedding being arranged between adjacent two cement concrete plates and the elasticity concrete layer that exposes the upper surface, described elasticity concrete layer is positioned at splicing seams top and width greater than splicing seams.

As preferably:

Described elasticity concrete layer bottom is provided with the cover plate that splicing seams is covered; Cover plate is set guarantees that the supporting surface of enough rigidity is arranged at splicing seams top, prevents depression.

Described cover plate is corrosion resistant plate; Structural strength is higher, and can not get rusty affects quality, satisfies simultaneously the flexible needs of concrete plate.

Described obturator is sponge; Soaking effect is better, and stroke is large.

The width of described elasticity concrete layer is 50mm to 70mm, is highly 50mm.

The beneficial effect of the cement pavement structure of the utility model gained is:

1, elasticity concrete layer embeds and is arranged between adjacent two cement concrete plates and splicing seams can be sealed, and splicing seams is interior is difficult for water inlet, so the cement concrete plate is difficult for subsiding because of too much distortion of roadbed water inlet of below;

2, elasticity concrete layer intensity is high, good impact resistance, and good toughness is difficult for agingly, and more firm in splicing seams place structure, cement concrete plate corner angle are difficult under the vehicle tyre effect broken, so longer service life;

3, elasticity concrete layer has good deformation nature, can successfully manage cement concrete plate gap because of the variation of expanding with heat and contract with cold or External Force Acting produces;

4, need not to adopt reinforcing bar to connect, construction technology is simple, and curing time is short, only needs 1-2 hour, can effectively shorten construction period.

The specific embodiment

The utility model will be further described by reference to the accompanying drawings below by embodiment.

Embodiment 1:

As shown in Figure 1, the described cement pavement structure of the present embodiment, be spliced by some cement concrete plates 1, be provided with splicing seams 2 between adjacent two cement concrete plates 1, be provided with sponge obturator 3 in splicing seams 2, obviously, obturator 3 can also be this area other packing material commonly used, also comprise embedding being arranged between adjacent two cement concrete plates 1 and the elasticity concrete layer 4 that exposes the upper surface, described elasticity concrete layer 4 is positioned at splicing seams 2 tops and width greater than splicing seams 2.The width of described elasticity concrete layer 4 is 50mm to 70mm, is highly 50mm, certainly can also select according to actual needs other size.

The beneficial effect of the described cement pavement structure of the present embodiment is:

1, elasticity concrete layer 4 embeds and is arranged between adjacent two cement concrete plates 1 and splicing seams 2 can be sealed, the interior difficult water inlet of splicing seams 2, so cement concrete plate 1 is difficult for subsiding because of too much distortion of roadbed water inlet of below;

2, elasticity concrete layer semi-finals degree is high, good impact resistance, and good toughness is difficult for agingly, and more firm in splicing seams 2 place's structures, cement concrete plate 1 corner angle are difficult under the vehicle tyre effect broken, so longer service life;

3, elasticity concrete layer 4 has good deformation nature, can successfully manage cement concrete plate 1 gap because of the variation of expanding with heat and contract with cold or External Force Acting produces;

Embodiment 2

As shown in Figure 2, the described cement pavement structure of the present embodiment, described elasticity concrete layer 4 bottom are provided with the cover plate 5 that splicing seams 2 is covered as different from Example 1; Cover plate 5 is set guarantees that the supporting surface of enough rigidity is arranged at splicing seams 2 tops, can not get rusty and affect quality, satisfy simultaneously the flexible needs of concrete plate.Prevent depression.

Specific embodiment described herein is only to design of the present utility model explanation for example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
