Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway construction, in particular to a grouting device for the edge of cement stabilized macadam. Background Technique
[0002] During the construction of the cement base layer of a highway, uneven mixture gradation, more coarse aggregates, less fine aggregates, lack of slurry or even segregation are likely to occur at the edge position of the highway and in the central isolation belt. After the cement base layer solidifies, honeycombing and pitting will form at the edge position, resulting in insufficient strength. In severe cases, the base layer will be loose and broken, and phenomena such as formwork collapse and edge collapse will occur.
[0003] In the traditional construction process, the widened width of the road surface is generally 10% of the designed width. Quality common problems such as insufficient compaction degree, looseness, edge collapse, and hollowing are likely to occur at the edge of the water-stable base layer. The traditional treatment measures generally adopt manual grouting and subsequent cutting of the redundant edge cement stabilized macadam. The process is complex and easy to cause material waste, and it is difficult to be applicable to large-scale and time-consuming water-stable construction. To solve the problems of insufficient compaction degree at the edge of the water-stable layer, insufficient edge strength, and reduction of quality common problems, the utility model designs a grouting device for the edge of cement stabilized macadam. Content of the Utility Model
[0004] To solve the problems in the background technique, the utility model proposes a grouting device for the edge of cement stabilized macadam, which effectively improves the compaction degree and strength of the edge of the water-stable layer.
[0005] To solve the above problems, the utility model adopts the following technical scheme: A grouting device for the edge of cement stabilized macadam, including a barrel body, a mounting seat, a stirring structure and a grouting structure. The barrel body is used to be arranged on a paver. The top of the barrel body is open. The mounting seat is arranged at the top opening of the barrel body. A controller is arranged on the mounting seat. The top of the stirring structure is arranged on the mounting seat, and the bottom of the stirring structure extends downward to the inner bottom of the barrel body. The stirring structure includes a driving motor, a stirring rod and stirring blades. The driving motor is arranged on the mounting seat and is externally connected to a power supply. The driving motor is electrically connected to the controller. The upper end of the stirring rod is connected to the driving motor, and the lower end of the stirring rod is provided with the stirring blades. The grouting structure is arranged on the outer side of the lower part of the barrel body and is connected to the inside of the barrel body.
[0006] Furthermore, the mounting seat includes a cross beam and a bracket. The two ends of the cross beam are respectively welded to both sides of the top of the barrel body. The bracket is welded on the cross beam. The stirring structure and the bracket are detachably connected by bolts.
[0007] Further, the grouting structure includes an opening and closing ball valve, a spray head pipe, and an extension pipe. The spray head pipe is disposed through the bottom side of the barrel body. The inner end of the spray head pipe extends into the inner bottom of the barrel body, and the outer end of the spray head pipe extends out of the outer side of the barrel body. The opening and closing ball valve is disposed inside the outer end of the spray head pipe, and the extension pipe is communicatively connected to the outer end of the spray head pipe.
[0008] Still further, the stirring blades include at least two stirring parts. At least two said stirring parts are evenly spaced along the circumferential direction of the stirring rod, and stiffening plates are vertically arranged on the tops of at least two said stirring parts.
[0009] Further, the stirring blades further include at least two stirring plates. At least two said stirring plates are overlapped and connected to at least two said stirring parts in a one-to-one correspondence. The sides of at least two said stirring plates close to the inner wall of the barrel body are arc-shaped.
[0010] Further, two handles are symmetrically arranged on the left and right sides of the outer side of the barrel body.
[0011] The beneficial effects of the present utility model: By injecting water and cement into the barrel body of the present utility model, the mounting seat provides mounting for the stirring structure and the controller. The driving motor drives the stirring rod and the stirring blades to rotate, so as to mix the cement and water in the barrel body evenly into slurry. Since the cement stabilized macadam side grouting device is installed on the paver, the slurry in the barrel body is sprayed onto the side of the paving surface through the grouting structure and then infiltrates into the gaps between the aggregates, so as to improve the aggregate strength at the side and reduce the phenomenon of edge collapse after form removal. Compared with the disposal measures of manually grouting and subsequently cutting off the redundant side cement stabilized macadam in the traditional scheme, the present utility model effectively improves the compaction degree and strength of the water stable side.
