Abstract
The utility model relates to a pavement crack repairing device. As the nozzle of the existing filling and sealing machine is too large, asphalt cannot be filled into a narrow crack and efficiency of repairing pavement cracks is low. According to the utility model, a cavity type discharge bin is arranged, a receive port is arranged at the top of the discharge bin, multiple connecting hoses are arranged at the bottom of the discharge bin, and discharge needle heads are arranged at the tail ends of the connecting hoses; heating wires are wound outside the discharge bin and the connecting hoses, and thermal insulation layers are wrapped outside the heating wires; and further, control valves are arranged at the connection parts of the bottom of the discharge bin and the connecting hoses. The pavement cracking repairing device can go deep into the bottom of a crack and can inject an asphalt filing material into the pavement crack from bottom to top, without slotting, so that the crack filling efficiency is improved and the use is simple and convenient.
Description
Technical field
The utility model belongs to the pavement engineering equipment technical field, is specifically related to a kind of pavement crack prosthetic device.
Background technology
Flexible pavement is the ubiquitous problems in countries in the world at the operating period cracking, the harm of pavement crack is constantly to enter moisture from the crack, and even roadbed is softening to make basic unit, causes the road surface depression of bearing force, produce the diseases such as purt slurry, step, check crack, thereby accelerate pavement destruction.The main cause of Asphalt Pavement Cracking can be divided into two large classes: a kind of is the structural destruction crack that the effect due to traffic load produces, and generally is referred to as Load Crack.Another kind is mainly the thermal cracking that produces due to the asphalt surface course variations in temperature, comprises low-temperature shrink crack and fatigue crack, generally is referred to as the non-loaded type crack.
The reparation in road pavement crack mainly relies on pitch cementation of fissures method, and two kinds of the artificial cementation of fissures and the pouring machine cementation of fissures are arranged.Wherein, artificial cementation of fissures method labour intensity is large, and efficient is low; Filling and sealing machine can improve cementation of fissures efficient, but also exist shortcoming, such as nozzle is too large, can not make pitch pour into tiny crack, need fracture to slot after the cementation of fissures again, artificially enlarged crack etc.
Summary of the invention
The purpose of this utility model is to provide and a kind ofly can be deep into Slit bottom in the situation that do not slot, from bottom to top the pitch potting compound is poured into the pavement crack prosthetic device of pavement crack.
A kind of pavement crack prosthetic device, its special character is: described device is provided with the discharging bin of cavity shape, and the discharging bin top is provided with material receiving port, and the discharging bin bottom is provided with some connecting hoses, and the connecting hose end is provided with the discharging syringe needle.
Above-mentioned discharging bin is wound around the heating electric wire outward, and is coated with insulation layer at the heating electric wire.
Above-mentioned connecting hose is wound around the heating electric wire outward, and is coated with insulation layer at the heating electric wire.
Above-mentioned discharging bin bottom and the junction of connecting hose are provided with by-pass valve control.
The syringe needle diameter of above-mentioned discharging syringe needle is 3-10mm.
The utlity model has following advantage:
1, the utility model does not need fluting, especially can repair yet and need not slot less than the more tiny crack of 5mm, and having solved needs the problem of slotting before the pitch cementation of fissures.
2, the utility model can go deep into bottom pavement crack, and the cementation of fissures from bottom to top makes gap-grouting material fill up the crack, better reaches the purpose of repairing the crack.
3, the utility model can insert simultaneously several syringe needles and enters in the crack, has improved cementation of fissures efficient.
4, the utility model can be arranged on the discharging opening of existing pouring machine, and is easy to use.
Description of drawings
Fig. 1 is the utility model structure chart.
In figure, 1-material receiving port, 2-discharging bin, 3-by-pass valve control, 4-connecting hose, 5-discharging syringe needle.
The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of pavement crack prosthetic device described in the utility model is connected to pouring machine discharging opening place, is provided with the discharging bin 2 of cavity shape, and discharging bin 2 tops are provided with material receiving port 1, dock with the pouring machine discharging opening.Discharging bin 2 bottoms are provided with some connecting hoses 4, and connecting hose 4 ends are provided with discharging syringe needle 5.Can be wound around the heating electric wire outside discharging bin 2 and connecting hose 4, and at heating electric wire outer cladding insulation layer.The junction of discharging bin 2 bottoms and connecting hose 4 is provided with by-pass valve control 3, can adopt the type hand valve, is used for gauge tap and load.Discharging syringe needle 5 is the detachable tapered needle, and the syringe needle diameter is 3-10mm, is used for using when different seams is wide.
During use, first from the crack, dust impurity is blown out, several syringe needles of suitable diameter are inserted each section of crack side by side, with inserting the valve open at the syringe needle place in crack, pitch is poured in the crack, after the cementation of fissures is completed, syringe needle is extracted, namely complete reparation.
It is cited that content of the present utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solution of the present invention by reading manual of the present invention is claim of the present invention and contains.
