The construction process and the implementation principle of the invention are as follows:
when a road is built, firstly, a road body is built, then a groove 1 is dug between the edge of the road and a green belt, after the bottom of the groove 1 is tamped, a prefabricated part 2 is sequentially lifted into the groove 1, before the prefabricated part 2 falls to the ground, a fastening device 5 is installed, before the fastening device 5 is installed, an adjusting cylinder 544 is firstly rotated, two ejector rods 541 which are in threaded connection with the adjusting cylinder 544 are respectively driven to move towards two ends by the rotation of the adjusting cylinder 544, until push plates 542 on the ejector rods 541 are respectively abutted to the end surfaces of the connecting frames 51 on the sides close to each other, the adjusting cylinder 544 is continuously rotated, the two ejector rods 541 are continuously separated, so that the two connecting frames 51 are upwardly ejected towards opposite directions, the tension spring 53 is stretched until the distance between the two connecting frames 51 respectively corresponds to the distance between metal rings 6 on the prefabricated part 2; then, the fastening device 5 is sleeved on the end part of the prefabricated part 2, so that the two connecting frames 51 respectively correspond to the metal rings 6 on one of the prefabricated parts 2, the end parts of the two prefabricated parts 2 are close to each other and are abutted against each other for connection, and finally, the two connecting frames 51 are welded on the metal rings 6; then, the adjusting cylinder 544 is rotated reversely, so that the adjusting cylinder 544 drives the two push rods 541 to move towards each other until the overall length of the pushing member 54 is smaller than the length between the two connecting frames 51, and then the pushing member 54 is removed, thereby completing the installation of the preform 2 and the fastening device 5.
During the mutual approach of the preforms 2, the main ribs 31 at the end of one of the preforms 2 are inserted into the insertion holes 4 at the end of the other preform 2.
Next, the water permeable bricks 7 are laid on the top of the prefabricated member 2, and when the water permeable bricks 7 are laid, the first brick bodies 71 are first laid on the top of the prefabricated member 2 in such a manner that the lower end edges of the bases 711 are closely attached to each other, and then the second brick bodies 72 are inserted between the supporting bodies 712 of the first brick bodies 71, thereby completing the laying of the water permeable bricks 7.
And finally, paving the permeable terrace 8 above the permeable bricks 7 and compacting, wherein preferably, the colored sand-free concrete with the marking property is used as the material of the permeable terrace 8.
Above-mentioned prefabricated assembled town road drainage structure in follow-up use, extension spring 53 among fastener 5 can last to draw two prefab 2 near each other through link 51, make between its prefab 2 be in the state of tight butt all the time, when taking place earthquake or 2 bottom surfaces of prefab atress inequality lead to producing crack or dislocation between two prefab 2, prefab 2 resumes the normal position again after the short-term production displacement under extension spring 53's effect, last tight butt in order to carry out the drainage, fastener 5's setting has played the effect that effectively prevents disconnection or dislocation between the adjacent prefab 2.
When water is accumulated on the road surface, the accumulated water on the road seeps down to the water permeable bricks 7 through the water permeable terrace 8, then enters the top of the prefabricated member 2 through the gaps between the water permeable bricks 7 and the drainage grooves 713 on the water permeable bricks 7, and flows into the water flow channel in the prefabricated member 2 through the water inlet holes 21 to be drained away. Brick 7 permeates water has fixed shape, use brick 7 that permeates water to cover the back with 2 up end of prefab, can enough prevent that road surface debris from entering into in the inlet opening 21 and blocking up it, can make road surface water slowly down flow to 2 tops of prefab through brick 7 that permeates water again, and flow down from inlet opening 21 at the circulation in-process, guarantee the water permeability of inlet opening 21, and the terrace 8 that will permeate water sets up at the top of brick 7 that permeates water, not only can stably permeate water brick 7, prevent that it from rocking, and can make the ponding permeate down, and simultaneously, can also make the road surface keep level and smooth, prevent that the road surface is uneven and influence the traffic.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
