Abstract
The utility model discloses a lifting, leveling and grouting integrated device for a prefabricated concrete pavement, and belongs to the technical field of prefabricated, assembled and rapid repair of concrete pavements. The existing technology integrating lifting, leveling and grouting provides great convenience for the prefabrication, assembly and repair work of roads, but has some obvious defects. For example: the leveling screws are fixedly connected with the supports, when the precast slab is leveled, the supports and the leveling screws rotate together to abrade a base course of a road surface, so that the device sinks, and the adjusting effect of the device is influenced. And the resistance received when the leveling screw is rotated is very large, and the labor intensity of constructors is increased. In addition, the prior art has the problem that the grouting holes are arranged on the support seat to cause blockage. The device optimizes the grouting pore structure and adjusts the connection mode between the support and the leveling screw, thereby improving the leveling and grouting effects of the device, and reducing the labor intensity of constructors to a certain extent due to the arrangement of the steel balls.
Description
Technical Field
The utility model relates to a lifting, leveling and grouting integrated device for a prefabricated concrete pavement, and belongs to the technical field of prefabricated, assembled and rapid repair of concrete pavements.
Background
Today, the rapid development of economy, long-term traffic congestion due to the repair of damaged roads has not been allowed to occur. Although the traditional repairing mode is simple in process, the lane needs to be closed for a long time, the curing time is long, the construction period is long, and the traffic and economic development is seriously influenced. The precast and assembled concrete pavement rapid repairing technology can realize open traffic within a few hours, particularly for concrete roads, parking lots or airport pavements with damaged pavements and needing to be repaired in as short a time as possible. When the concrete pavement prefabrication, assembly and rapid repair technology is adopted to repair the pavement, the working links of hoisting, transporting and leveling the prefabricated slab and grouting the bottom of the prefabricated slab need to be carried out. The leveling of the precast slabs and the grouting working quality of the bottoms of the precast slabs greatly influence the service life of the pavement. Generally, when a factory produces precast concrete slabs, three different devices, i.e., a hoisting ring, a leveling device and a grouting pipe, are respectively poured into the precast slabs. During construction, the hoisting and transporting work of the precast slabs is completed through the hoisting ring, then the concrete precast slabs are leveled on a construction site through the leveling devices reserved in the slabs, and finally the bottoms of the precast slabs are grouted through the reserved grouting pipes, so that the phenomenon of the road surface coming off is prevented.
In recent years, some scientific researchers and field workers develop a device integrating three functions of lifting, leveling and grouting, which provides great convenience for the precast, assembled and quickly repaired work of a concrete pavement, but the device has some obvious defects. For example, when the existing device integrating three functions of hoisting, leveling and grouting is used for construction, because the leveling screws of the device are fixedly connected with the bottom support into a whole, the support can be driven to rotate together when the leveling screws are rotated for leveling. Like this, under concrete slab's action of gravity, support in the rotation can produce the destruction effect to the road surface basic unit, causes the subsidence of device, has greatly influenced the regulation effect of device, and the device sinks into the road surface basic unit and can plug up the slip casting hole even. Moreover, when the device is used by constructors to level the concrete precast slab, the resistance force applied when the leveling screws are rotated is very large, wherein a large part of the resistance force is transferred to the leveling screws by the support, so that the labor intensity of the constructors is very large. In addition, the grouting hole is arranged on the support by the conventional device, and the grouting hole can be blocked by a road base layer, so that the grouting effect of the device is seriously influenced. And the structural design of the grouting pore of the existing device is unreasonable, so that the grouting speed is small, and the construction is inconvenient.
