Description
Technical Field
The invention relates to road engineering, in particular to a municipal road rapid repairing structure and a construction method thereof.
Background
The asphalt concrete pavement cracks, and the asphalt concrete pavement should be sealed and repaired in time, so that rainwater and other impurities are prevented from entering a pavement structure layer and a roadbed along the cracks, the bearing capacity of the pavement is reduced, and the local or flaky damage of the pavement is accelerated.
At present, the common asphalt pavement crack pouring process is divided into two types of non-slotting crack pouring and slotting crack pouring, the non-slotting crack pouring is divided into a hot operation method and a cold operation method, the hot operation method generally adopts common hot asphalt or modified hot asphalt to carry out the encapsulation of the cracks of the cyan pavement, when the common hot asphalt is adopted, the common hot asphalt has low softening point under the condition of high temperature, the phenomenon of oil flooding and being taken away by vehicles easily occurs, and the common hot asphalt becomes brittle and is easy to fall off when being full of green at low temperature; the modified heat full green paint is adopted, and because the modified gradually green paint has high viscosity and poor fluid permeability, and the gradually green paint poured into the pavement cracks is very little, the pavement cracks are easy to crack when the pavement cracks expand at low temperature, and the service life of repairing is short. The cold operation method is to use liquid drowning (emulsifying) polymer to modify liquid gradually-turning green and to encapsulate. Because the solvent is added into the gradual green of the polymer modified liquid, the low-temperature fluidity permeability of the gradual green is improved, but the high-temperature stability and the elastic recovery performance are reduced, the gradual green is easy to overflow and be taken away by vehicles to pollute the road surface in summer, and the gradual green is easy to pull and handy in winter. Therefore, the slot is not opened for crack pouring, the repaired crack is re-cracked at the original crack pouring position after a period of time, and a plurality of unchangeable and unsafe factors are caused to the travelling crane by each repair and maintenance operation.
The process method generally comprises the steps of cutting the pavement cracks forcibly through machinery to widen and deepen the pavement cracks, and then pouring the crack pouring glue to fill and seal the pavement cracks.
At present, the slotting and crack pouring of the asphalt pavement is most commonly in a 'square groove pouring type', and the slotting and crack pouring construction process flow is as follows: preparation work (including construction area closure), slotting, gap cleaning, gap filling and open traffic, wherein:
preparation work: inspecting the grooving machine and the crack pouring machine to ensure that the technical conditions are good; determining a crack repairing design scheme according to the concrete condition of the pavement crack; starting a crack pouring machine, adding the sealant into a sealant heating tank, heating the sealant, and stirring to a specified temperature; during heating, the crack sealing machine is pulled behind the truck, and sealant, partition wall, safety indication plate, groover, shoulder-back blower, etc. are installed on the truck and pulled to the preset construction site to enclose half of the road as construction area.
Grooving: and (4) adjusting the grooving depth of the grooving machine in advance according to the designed grooving size, and then performing grooving operation. During operation, the size of the groove is adjusted in time according to the width type of the crack, the minimum design requirement is met, and the minimum width requirement is met. When the notching machine runs, the cutting blade is kept to be matched with the crack.
Gap cleaning: and thoroughly cleaning dust in a range of thoroughly cleaning broken slag in the groove and dust in a range of at least 10cm on two sides of a crack by using a blower or a shoulder-back blower of the crack pouring machine, and ensuring that the notch is clean and dry.
Pouring a seam: when the temperature is changed to 5 ℃, the crack sealing machine needs to be provided with preheating equipment to preheat the groove part, and if the crack sealing machine is not preheated at the temperature, the bonding force of the sealant can be reduced; if the temperature is higher than 5 ℃, the preheating is not needed, but the preheated gap-filling effect is good. When the heating temperature of the sealant reaches about 190 ℃, the sealant is uniformly filled into the groove by a pressure nozzle with a strickle on the crack pouring machine, and the sealant is dragged to form a sealing layer with a certain width and thickness on two sides of the crack.
Opening traffic: after the sealant is used for pouring the seams, the traffic can be opened after the sealant is fully cooled and the broken slag on the road surface is cleaned.
When the road crack is great, the square groove can be seted up great to lead to filling the square groove and need using a large amount of cementation of fissures materials, a large amount of cementation of fissures materials take place deformation more easily, and life is not long.
Therefore, a new solution is needed to solve this problem.
