Embodiment

[0041] The method for producing emulsified asphalt slurry and injecting slurry into longitudinal cold joints of road surfaces according to the present invention is specifically as follows:

[0042] S1. Add the required cement and emulsified asphalt into the slurry processing device;

[0043] S2. Turn on the power and power generation device. After the power and power generation device is running stably, open the whey processing device. The whey processing device completes the mixing of the whey according to the slow-medium-fast stirring method, and maintains continuous slow stirring state;

[0044]S3. Turn on the control system. One person controls the walking and pulping of the vehicle. This person opens the walking device; the other person controls the milk slurry pouring device, which includes a drainage assembly and a pouring rod assembly. This person aligns the pouring rod assembly Open the drainage assembly at the same time, and the slurry is introduced into the groutin...

Abstract

The invention discloses an emulsified asphalt emulsion slurry manufacturing and pavement longitudinal cold joint emulsion slurry pouring method, belongs to the field of road joint pouring in road construction, and aims to solve the technical problem of how to quickly and accurately complete slurry pouring at a cold joint splicing part and improve the joint quality, the adopted technical scheme isas follows: the method specifically comprises the following steps: S1, required cement and emulsified asphalt are added into an emulsion slurry processing device; S2, a power and power generation device is started, after the power and power generation device operates stably, a milk processing device is started, the milk processing device completes mixing of milk according to a slow-medium-fast stirring mode, and a continuous slow-speed stirring state is kept; S3, a control system is started, vehicle walking and slurry discharging are controlled by one person, and a walking device is started bythe person; and the other person controls the milk slurry pouring device, aligns the pouring rod assembly to the joint and opens the drainage assembly, and the slurry is guided into the grouting headof the pouring rod assembly through the soft guide pipe.

Description

technical field [0001] The invention relates to the field of road joint grouting in road construction, in particular to a method for producing emulsified asphalt slurry and pouring the grout into longitudinal cold joints of road surfaces. Background technique [0002] With the gradual increase of road reconstruction and expansion technology in recent years, there are more and more longitudinal overlaps of old and new road structures, mainly involving the lapping of new and old water-stabilized bases, the lapping of old water-stabilized bases and asphalt cold recycled materials, and the old asphalt pavement Lap with asphalt cold recycled material. However, in the existing pavement design, there is no special design and special equipment for splicing. In the design of road structure, ensuring the integrity of the road structure layer is the key to ensuring the service life of the road, and the splicing of roads in reconstruction and expansion is prone to large longitudinal in...
