Abstract
The utility model discloses a novel road surface prefabricated section, including ordinary type prefabricated section and interlocking type prefabricated section, ordinary type prefabricated section and interlocking type prefabricated section bottom all are provided with the recess that equals with the prefabricated section width, ordinary type prefabricated section and interlocking type prefabricated section top surface all are provided with the chamfer all around. This novel rational in infrastructure, convenient construction, can alleviate the phenomenon that appears loose, the height is uneven between each block after the construction, can realize the novel road surface prefabricated section of safe driving.
Description
Technical Field
The utility model relates to a novel road surface construction field specifically indicates a novel road surface prefabricated section.
Background
The precast block is made of cement concrete as main raw material through processing, vibration pressurizing or other forming processes, and is used for paving the road surface of urban roads, rural highways, ports, wharf yards and other occasions.
As shown in fig. 1, a conventional road surface prefabricated block is generally divided into a general prefabricated block body 1 'and an interlocking prefabricated block body 2', and in order to realize an interlocking function between blocks, the prefabricated block body 1 'is laid in an extending type or a herringbone type, the prefabricated block body 2' has a structure of engaging tooth edges, and blocks can be interlocked to prevent displacement and dislocation of each brick during laying. However, the road surface paved by the precast blocks is loose and uneven due to repeated load action and loss of joint sand, so that the service performance of the road surface is affected, and the uneven precast block road surface has potential safety hazards to a certain extent.
Disclosure of Invention
The utility model aims at the not enough of prior art, provide a simple structure, the installation is convenient, can alleviate the novel road surface prefabricated section of loose, the uneven phenomenon of height appearance between the prefabricated section in the work progress.
In order to achieve the above object, the utility model relates to a novel road surface prefabricated section, including ordinary type prefabricated section and interlocking type prefabricated section, its characterized in that: the bottom of each of the common precast block and the interlocking precast block is provided with a groove with the same width as the precast block, and the top surfaces of the common precast block and the interlocking precast block are all provided with chamfers.
Further, the cross section of the groove is triangular or rectangular and can be selected according to actual needs.
Furthermore, the chamfer is a 3mm chamfer, so that extrusion abrasion between the precast blocks in the construction process and scratch of the precast block acute angle to constructors can be avoided.
Further, the width of recess is 3 ~ 5cm, and the recess can fully contact with the sand cushion layer under the prefabricated section surface course, provides horizontal frictional resistance, strengthens the interlock effect of prefabricated section.
Further, the depth of the groove is 1.5-2.5 cm. Considering the thickness of the sand cushion layer, the depth of the groove is not more than 2.5cm, and the mechanical property of the precast block is greatly influenced by the overlarge depth
Further, the distance between the grooves is 3-5 cm, the distance between the grooves and the width of the grooves are consistent, and construction of the precast block can be facilitated.
Further, the distance between the groove close to the edge of the precast block and the edge of the precast block is 2-3 cm. This is determined by the maximum particle size of the aggregate of the precast block
The utility model has the advantages that:
the utility model discloses the structural style of road surface prefabricated section bottom surface recess makes the prefabricated section have better contact with the sand bed course below the block, and the sand bed course can provide bigger horizontal frictional resistance, has strengthened the fastness that the level was laid, has strengthened the interlocking performance on prefabricated section road surface. And the grooves are fully contacted with the sand cushion layer, the sand cushion layer can better diffuse load under the load effect, the phenomena of looseness and unevenness of blocks of the prefabricated block pavement after construction are relieved, and safe driving can be realized.

Detailed Description
The invention will be described in further detail with reference to the following figures and specific embodiments:
as shown in fig. 2 to 5, the present embodiment discloses a novel road surface precast block, which includes a common type precast block 1 and an interlocking type precast block 2, wherein a chamfer of 3mm should be arranged around the top surfaces of the common type precast block 1 and the interlocking type precast block 2. The appearance quality, the dimensional accuracy, the compressive strength, the bending strength and the freezing resistance of the precast block meet the standard requirements. The bottom surface of the precast block body is provided with a groove 3 with the same width as the precast block, and the groove 3 can be a rectangular or triangular groove and can be selected by self according to actual conditions. The width of the groove 3 is 3-5 cm, the depth of the groove 3 is 1.5-2.5 cm, and the distance 4 between the grooves is 3-5 cm. The groove close to the edge of the prefabricated block is 2-3 cm away from the edge of the prefabricated block, namely the width of the edge 5 of the bottom surface of the block is 2-3 cm.
Wherein, the width of recess 3 is close or equals with recess interval 4, and the block prefabrication of this kind of structure being convenient for, convenient construction.
The depth of the groove 3 is 1.5-2.5 cm, which is determined by the thickness of the sand cushion layer, the depth of the groove is not more than 2.5cm, and the mechanical property of the precast block is greatly influenced by overlarge depth.
The width of the bottom edge 5 of the block body is 2-3 cm, which is determined by the maximum particle size of the prefabricated block aggregate.
The utility model discloses the structural style of road surface prefabricated section bottom surface recess makes the prefabricated section have better contact with the sand bed course below the block, and the sand bed course can provide bigger horizontal frictional resistance, has strengthened the fastness that the level was laid, has strengthened the interlocking performance on prefabricated section road surface. And the grooves are fully contacted with the sand cushion layer, the sand cushion layer can better diffuse load under the load effect, the phenomena of looseness and unevenness of blocks of the prefabricated block pavement after construction are relieved, and safe driving can be realized.
It should be noted that: the above description is only intended to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to examples, those of ordinary skill in the art will understand that: modifications may still be made to the solutions described in the previous examples, or equivalents may be substituted for the concave guide rail features; without departing from the essence of the technical solution of the present invention, it is covered in the technical solution scope of the present invention.
