Abstract
The invention relates to a pavement crack repairing device. A filling and sealing machine can not be used for filling asphalt into tiny cracks due to an overlarge nozzle and is low in efficiency for repairing pavement cracks. The pavement crack repairing device is provided with a cavity-shaped discharging bin, the top of the discharging bin is provided with a receiving hole, the bottom of the discharging bin is provided with a plurality of connection hoses, and the tail ends of the connection hoses are provided with discharging pinheads; an electric heating wire is wound outside the discharging bin and the connection hoses, and a heat insulation layer is coated outside the electric heating wire; and control valves are arranged at the joints of the bottom of the discharging bin and the connection hoses. The pavement crack repairing device can extend into the bottom of a crack under the condition that no slot is formed, can be used for filling and sealing the asphalt into pavement cracks from bottom to top, and is capable of increasing the crack filling efficiency and simple and convenient in use.
Description
Technical field
The invention belongs to the pavement engineering equipment technical field, be 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, makes basic unit even roadbed softening, 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 owing to traffic load produces, and generally is referred to as Load Crack.Another kind mainly is the thermal cracking that produces owing 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, and is too large such as nozzle, 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 invention is to provide and a kind ofly can in the situation of not slotting, be deep into Slit bottom, the pavement crack prosthetic device that the pitch potting compound is poured into pavement crack from bottom to top.
The 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 twines the heating electric wire outward, and is coated with insulation layer at the heating electric wire.
Above-mentioned connecting hose is twined the heating electric wire outward, and is coated with insulation layer at the heating electric wire.
Above-mentioned discharging bin bottom is provided with by-pass valve control with the junction of connecting hose.
The syringe needle diameter of above-mentioned discharging syringe needle is 3-10mm.
The present invention has the following advantages:
1, the present invention does not need fluting, especially can repair less than the more tiny crack of 5mm yet and need not slot, and having solved needs the problem of slotting before the pitch cementation of fissures.
2, the present invention can go deep into the pavement crack bottom, 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 present invention can insert simultaneously several syringe needles and enters in the crack, has improved cementation of fissures efficient.
4, the present invention can be installed in the discharging opening of existing pouring machine, and is easy to use.
Description of drawings
Fig. 1 is structure chart of the present invention.
Among the figure, 1-material receiving port, 2-discharging bin, 3-by-pass valve control, 4-connecting hose, 5-discharging syringe needle.
The specific embodiment
The present invention will be described in detail below in conjunction with the specific embodiment.
Pavement crack prosthetic device of the present invention 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, docks 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 twine the heating electric wire outside discharging bin 2 and the 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, from the crack, dust impurity is blown out first, 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 finished syringe needle is extracted, namely finish reparation.
It is cited that content of the present invention 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.
