Technical Field
The invention belongs to the technical field of pavement restoration, and particularly relates to a concrete precast block for restoring a cement road.
Background
After the cement road is used for a period of time, various problems of damage and deformation cracking can occur in succession, the damaged cement road needs to be repaired in time, the existing common technology is to pull the damaged part open and repair or pour the damaged part again by concrete, the method has low construction efficiency and high cost, the process is improved at present, a prefabricated module is generally adopted to repair the damaged road, for example, the road rapid building method disclosed by the patent of CN03115403.4 and the prefabricated part used by the method adopt a splicing block assembly mode, and the prefabricated part can be manufactured in advance for standby in a workshop in large quantity, so that the road can be put into use after the prefabricated part is spliced and fixed after the roadbed construction is finished. The maintenance speed is fast, for example when the prefabricated part breaks because of the subgrade sinks, only need fill the subgrade and restore to former subgrade level, change new prefabricated part and can use. However, the prefabricated module still has obvious defects in the using process: 1. gaps between the prefabricated part bodies and the old pavement do not have a waterproof function, and water is easy to seep in rainy days, so that the subgrade is soaked in water and then collapses or soil and water is lost, and the pavement or the prefabricated part loses support and is easy to damage; 2. the prefabricated module is not completely integrated with the roadbed and the pavement into a whole, the time is long, the prefabricated module is loosened in the pit, and finally, the prefabricated module is easy to damage and needs to be repaired for the second time.
Disclosure of Invention
In order to solve the problems, the invention discloses a concrete precast block for repairing a cement road, which has the advantages of short repairing time, good waterproof performance, stable fusion with a roadbed and a pavement and long service life.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the utility model provides a concrete precast block that restoration cement road was used, includes the precast block body, the precast block body is the chamfered frustum type, and is big-end-up, the precast block body sets up in the road bed that needs were filled, be the slope that upwards extends between road bed to the road surface, be equipped with the caulking between the side of slope and precast block body, road bed below is buried has four at least nuts, and square structure is constituteed to a plurality of nuts, and the nut outside is equipped with vertical baffle, and vertical division has the through-hole that corresponds with the embedded nut position on the precast block body, and the through-hole top is equipped with the step, and precast block body lower plane edge is equipped with the recess, be equipped with waterproof strip in the recess, the step below is equipped with the intercommunicating pore, is equipped with the reinforcement groove between each planar edge on the precast block body step top.
As an improvement of the invention, 1-3 semicircular grooves are formed on the slope.
As an improvement of the invention, the precast block body is internally provided with a steel bar.
The invention has the beneficial effects that:
the concrete precast block for repairing the cement road has the advantages of short repairing time and good waterproof performance, and the precast block body, the roadbed and the road surface are stably fused by arranging the communication holes, the reinforcing grooves and the semicircular grooves, so that the concrete precast block has long service life.
