Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-4, a administer flexible road surface structure of nail hole formula of unstable subsidence of road, constitute by a plurality of panel unit 1 interconnect, panel unit 1 includes the panel body 6 of rectangle, a set of adjacent limit lateral part of panel body 6 is equipped with down boss 2, the bottom surface of lower boss 2 flushes with the bottom surface of panel body 6, the top surface of lower boss 2 is less than the top surface of panel body 6, another set of adjacent limit lateral part of panel body 6 is equipped with last boss 3 with lower boss 2 matched with, the top surface of last boss 3 flushes with the top surface of panel body 6, the bottom surface of last boss 3 is higher than the bottom surface of panel body 6, lower boss 2 top surface is equipped with a plurality of jacks 4, last boss 3 bottom surface is equipped with the insert nail 5 with jack 4 one-to one, form the whole road surface through last boss 3 and lower boss 2 mutual concatenation between the adjacent panel unit 1, connect through inserting nail 5 and jack 4 cooperation between last boss 3 and the lower boss 2 of concatenation each other.
The inserted nail 5 is pre-buried in the upper boss 3. The upper end of the inserted nail 5 is bent.
The panel unit 1 is formed by pouring concrete. And a reinforcing steel bar mesh is arranged in the panel unit 1 and formed by criss-cross connection of transverse reinforcing steel bars 7 and longitudinal reinforcing steel bars 8.
The gaps between adjacent panel units 1 are filled with asphalt cement 9.
The inserting nail 5 is inserted into the inserting hole 4 by 50-80 mm.
The hole pitch of the upper insertion hole 4 of the lower boss 3 is 400-500 mm.
The side length of the panel body 6 is 1.5-2m, and the thickness is 140-300 mm.
The inserted nail 5 is made of steel bars, and the outer diameter of each steel bar is 20-25 mm; the inner diameter of the jack 4 is 28-35 mm.
The construction method comprises the following steps:
A. dismantling the original sunk pavement, and filling and tamping the foundation of the sunk part with loess;
B. splicing the panel units 1 into a whole road surface through the upper bosses 3 and the lower bosses 2, and inserting the inserting nails 5 on the upper bosses 3 into the inserting holes 4 on the lower bosses 2 in a one-to-one correspondence manner in the splicing process;
