Problems solved by technology

With the decrease of petroleum resources, the price of asphalt is gradually increasing and the output is decreasing. The production of asphalt materials and the construction of asphalt roads will inevitably cause environmental pollution, and the laying of existing asphalt roads has to use a large amount of sand. Stone, for urban road construction, the construction process using sand and gravel is not environmentally friendly, and sand and gravel materials are not easy to obtain
[0003] In recent years, the pressure on road maintenance and reconstruction and expansion projects to traffic disturbance has continued to increase. The allowable construction time for the maintenance, reconstruction and expansion of runways in airports, high-traffic highways and urban roads is limited. Existing conventional roads The repair and construction time occupied by repair and reconstruction and expansion is too long, so the road cannot be put into use soon

[0050] Such as figure 1 As shown, the embodiment of the present invention provides a prefabricated road construction method 100, which includes the following steps, and is characterized in that: 101 performing road surface detection on the surface to be paved and dividing the road surface area; 102 performing pavement prefabrication at the prefabrication site; The 104 crane lifts the prefabricated pavement to the paved surface and assembles the prefabricated pavement; the 105 grouting truck pump grouts the bottom of the pavement; figure 2 Shown is a schematic diagram of the fabricated pavement structure after construction by this construction method.

[0051] Firstly, the thickness distribution of the surface to be paved is detected, and the thickness of the surface layer of the surface to be paved is collected by ultrasonic array non-destructive testing equipment; in this embodiment, the ultrasonic array testing equipment adopts PL200-PE equipment, which uses point scanning ...

[0059] This embodiment relates to a prefabricated road, which is obtained through the construction method in the first embodiment.

[0060] The road obtained by the construction method of the first embodiment, because the pavement is prefabricated in the special site for pavement prefabrication, when the road is repaired and laid, only the base layer of the paved road needs to be destroyed and leveled, which is different from ordinary Compared with the road construction method, the time for pouring, flattening and forming of the road surface is saved, and the time for road repair is greatly shortened. Especially for the maintenance of urban traffic core roads and airport roads, the allowable repair and laying time is limited. The road is formally based on this and offers the possibility to repair and pave the road in a short period of time. In addition, sensor elements are buried at the pavement level, which can sense the actual usage status of the pavement and passing vehicle...

Abstract

The invention relates to a fabricated road construction method. The fabricated road construction method is characterized in that the fabricated road construction method comprises the following steps that road surface detection and road surface regional division are conducted on a to-be-paved road surface; pavement prefabricating is conducted in a pavement prefabricating site according to road surface regional division; the to-be-paved road surface is broken and removed through an excavator, and base course leveling is conducted; a pavement is divided according to the region and hoisted to theto-be-paved road surface by a hoisting machine through hoisting holes in the to-be-paved road surface; the prefabricated pavement is assembled through a joint structure; and grouting treatment is conducted at the bottom of the pavement through a grouting car pump. According to a road paved through the fabricated road construction method, the pavements for road paving are all prefabricated in a special prefabricating site, after being well fabricated, the pavements are transported to a construction site to be subjected to paving assembly, assembly is quick and easy, the construction period is greatly shortened, the traffic interference to cities is small, and convenience is brought to quick restoring and smoothness of city roads.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an assembled road construction method. Background technique [0002] There are two common ways to build roads, one is pouring concrete road construction, and the other is asphalt rolling road construction. Pouring concrete road construction first needs to set formwork on the base, and then lay concrete in the area surrounded by formwork. During the laying process, it is necessary to use tank trucks to transport the concrete to the construction site, and then dump the concrete in the tank trucks to the road to be constructed. The vibrator fully vibrates the concrete and scrapes it. Finally, it is necessary to cut expansion joints on the hardened road surface. A series of operations. Asphalt rolling road construction first paves the road base, then paves the road base structure layer, and the third layer For the asphalt macadam, the final paving stone pin surface. With ...
