Further, the interlayer thread is assembled on the threaded rod, and the interlayer thread is assembled on the outer peripheral wall of the threaded sleeve.

By adopting the technical scheme, the interlayer can be conveniently moved and fixed.

Further, the buffer layer is an asbestos plate.

By adopting the technical scheme, the asbestos plate has strong anti-load capacity and tension resistance, and can relieve the load caused by frost expansion.

Furthermore, a plurality of round holes are arranged on the asbestos plate.

Through adopting above-mentioned technical scheme, pitch can flow into in the round hole, treats that pitch solidifies the back, and the asbestos board can be similar to inlay on the pitch surface.

To sum up, the beneficial effects of the utility model are that: 1. the buffer layer can be used for slowly thawing the load caused by expansion so as to relieve the unevenness of the surface of the runway caused by the expansion due to freezing; 2. the expansion prevention means may enhance the stability of the buffer layer, thereby enhancing the tensile strength of the buffer layer.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The first embodiment is as follows:

referring to fig. 1, for the utility model provides a prefabricated type plastic course, the cladding is in proper order at basic unit 1, thick pitch layer 2, metalling 3, thin pitch layer 4, elastic layer 5, surface course 6 on ground. Geotextile buffer layers 7 are arranged between the coarse asphalt layer 2 and the gravel layer 3 and between the fine asphalt layer 4 and the gravel layer 3.

The geotextile has good tension resistance and bearing capacity, can buffer the load coming from freezing and further can relieve the unevenness of the surface of the runway.

The geotextile cushioning layers 7 described above are fixed on both sides of the gravel layer 3 by the expansion preventing means 8. Referring to fig. 2, here, the expansion preventing device 8 is a structure with an i-shaped longitudinal section, which is composed of a top seat 81, a base 82, a threaded rod 83, a threaded sleeve 84 and an interlayer 85, and the specific structure is as follows:

a threaded sleeve 84 is integrally formed in the center of the base 82, and a threaded rod 83 is integrally formed in the center of the top seat 81, wherein the threaded rod 83 can be threadedly fitted in the threaded sleeve 84; the insert 85 is provided with two inserts (85 a; 85b), one insert 85b being screw-fitted on the threaded rod 83 between the top seat 81 and the end of the threaded sleeve 84, and the other insert 85a being screw-fitted on the outer peripheral wall of the threaded sleeve 84;

the specific installation mode is as follows: firstly, installing a base 82 on the coarse asphalt layer 2, enabling a threaded sleeve 84 to face upwards, then laying a first layer of geotextile, enabling the threaded sleeve 84 to penetrate through the geotextile, then installing a first interlayer 85 on the threaded sleeve 84, and clamping the first layer of geotextile between the base 82 and the first interlayer 85; clamping a second layer of geotextile by using a threaded rod 83 with a second interlayer 85, and installing a top seat 81 on a threaded sleeve 84; and laying the gravel layer 3 again, enabling the matched threaded sleeve 84 and the threaded rod 83 to penetrate through the gravel layer 3, and enabling a second layer of geotextile to be laid on the surface of the gravel layer 3. Thus, the geotextile cushion layer 7 may be sandwiched between the interlayer 85b (or 85a) and the top chassis 81 (or the bottom chassis 82) to fix the geotextile cushion layer 7 on the gravel layer 3.
