Abstract
The utility model discloses a kind of precast concrete block for down-hole repairing road, belongs to engineering field.This precast concrete block thickness of slab 200-300mm, and two ends have curved edge, precast concrete block end face is provided with two reinforcing bar suspension ring, these reinforcing bar suspension ring to be directly embedded in advance in precast concrete block and to weld with the cage of reinforcement in precast concrete block, described cage of reinforcement is rectangular, and described cage of reinforcement comprises rectangle reinforcing bar and is welded in the diagonal angle reinforcing bar on rectangle reinforcing bar.Its beneficial effect is: down-hole road rehabilitation is quick, and guarantor's down-hole road rehabilitation quality is high; The suitability for industrialized production of suitable down-hole road, reduces situ wet operation, saves material, reduces engineering cost, and the speed of reparation is fast, road surface good integrity, the good easy cleaning of self-cleaning, low-carbon environment-friendly.
Description
Technical field
The utility model relates to engineering field, refers to a kind of precast concrete block for down-hole repairing road especially, for repairing down-hole road fast.
Background technology
Existing construction temporary road often adopts concreting road surface, job site, rubble or slag road surface.The cast-in-situ concrete temporary pavement concrete curing time is long, and construction is easily subject to the impact of weather, produces noise, airborne dust and building waste, contaminated environment when removing.Rubble or slag road surface not easy cleaning, face, main line airborne dust is large, and watering and lowering dust is taken a lot of work water wasting, and road surface destructible, poor flatness, also will have one section of preserving period just can be open to traffic, waste time after building, often repairing affects road occupation, and unfavorable civilized construction.
Summary of the invention
The purpose of this utility model proposes a kind of precast concrete block for down-hole repairing road, and the suitability for industrialized production of suitable down-hole road, reduces situ wet operation, save material, reduce engineering cost, and the speed of reparation is fast, road surface good integrity, the good easy cleaning of self-cleaning, low-carbon environment-friendly.
For achieving the above object, a kind of precast concrete block for down-hole repairing road described in the utility model, this precast concrete block thickness of slab 200-300mm, and two ends have curved edge, precast concrete block end face is provided with two reinforcing bar suspension ring, these reinforcing bar suspension ring to be directly embedded in advance in precast concrete block and to weld with the cage of reinforcement in precast concrete block, and described cage of reinforcement is rectangular, and described cage of reinforcement comprises rectangle reinforcing bar and is welded in the diagonal angle reinforcing bar on rectangle reinforcing bar.
Cage of reinforcement weld in described reinforcing bar suspension ring and precast concrete block, is preferably one end and welding on rectangle reinforcing bar, the other end and diagonal angle reinforcement welding.
The curved edge at described precast concrete block two ends, when laying road surface, edge: the road surface, edge that can cover down-hole; When laying two pieces of precast concrete blocks are adjacent: better can be connected two pieces of precast concrete blocks.
Between described precast concrete block, 10-20mm is pressed in gap.
A kind of precast concrete block for down-hole repairing road described in the utility model, its beneficial effect is: down-hole road rehabilitation is quick, and guarantor's down-hole road rehabilitation quality is high; The suitability for industrialized production of suitable down-hole road, reduces situ wet operation, saves material, reduces engineering cost, and the speed of reparation is fast, road surface good integrity, the good easy cleaning of self-cleaning, low-carbon environment-friendly.

Detailed description of the invention
Embodiment 1
As shown in Figure 1, 2, down-hole damaged road surface block is divided, by dividing block according to damaged road surface, precast concrete block thickness of slab 200mm, and two ends have curved edge, precast concrete block end face is provided with two reinforcing bar suspension ring, these reinforcing bar suspension ring to be directly embedded in advance in precast concrete block and to weld with the cage of reinforcement in precast concrete block, described cage of reinforcement is rectangular, and described cage of reinforcement comprises rectangle reinforcing bar and is welded in the diagonal angle reinforcing bar on rectangle reinforcing bar; Cage of reinforcement weld in reinforcing bar suspension ring and precast concrete block, is preferably one end and welding on rectangle reinforcing bar, the other end and diagonal angle reinforcement welding; Between precast concrete block, 10mm is pressed in gap; Dismounting and the lifting of precast concrete block are all lifted by crane by reinforcing bar suspension ring, be convenient to transport, and cutting damaged road surface cuts out regular shape, chooses the opportunity of cutting damaged road surface, affects the production time short; Select proper moment fly-cutting damaged road surface after precast concrete block preserving period, precast concrete block is transported to down-hole fast and lays, adopt fine sand shop fixtures when laying prefabricated reinforced concrete block, between block and block, adopt concrete mortar jointing.
