Problems solved by technology

In the grouting construction process, it is necessary to spread the pouring materials. Due to the lack of professional automation equipment, it currently mainly relies on manual work, and the accuracy mainly relies on manual experience to judge, which leads to time-consuming and labor-intensive, low production efficiency, and seriously affects grouting. Integral quality of compound pavement

Embodiment 1

[0033] Specifically, as figure 1 As shown, a spreading device for pouring composite pavement of the present invention includes a pressing unit, a spreading unit and a control unit (not shown in the figure);

[0034] The pressing unit includes a first drive assembly 1 and a pressing plate unit 2;

[0035] The first driving assembly 1 is preferably a driving cylinder, the output shaft of which is connected to the platen unit 2, and receives the control signal from the control unit to drive the platen unit 2 to move up and down in the vertical direction, that is, to realize the pressing of the materials spread on the road surface. peaceful compaction;

[0036] The pressing plate unit 2 includes a pressing plate 201 and a plurality of vibrators 202. The pressing plate 201 is arranged parallel to the ground. In order to reduce material costs, the pressing plate 201 can be set as a hollow structure. Since the road surface is mostly a rectangular structure, this The pressing plate ...

Embodiment 2

[0046] Based on Embodiment 1, the difference between this embodiment and Embodiment 1 is that in the embodiment of the present invention, several distance measuring sensors (not shown in the figure) are also included, and the several distance measuring sensors are along the extending direction of the pressing plate. Installed at equal intervals on the outside of the side wall of the pressure plate (the side wall is opposite to the side wall provided with the second drive assembly), and located on the same horizontal plane, the output ends of each distance measuring sensor are connected to the control unit;

[0047] After finishing the first spreading and pressing, each ranging sensor measures the distance between the platen and the spreading material on the ground. After receiving all the distances, the control unit judges the monitoring point that needs to continue spreading, and controls the The second driving component drives the spreader to move to the monitoring point wher...

Abstract

The invention discloses a spreading device for a pouring type compound pavement. The spreading device comprises a pressing unit and a scattering device, wherein the pressing unit comprises a first driving assembly and a pressing plate unit; the first driving assembly is connected with the pressing plate unit and is used for driving the pressing plate unit to move up and down in the vertical direction; the pressing plate unit comprises a pressing plate and a plurality of vibrators; the plurality of vibrators are arranged on the pressing plate and are used for driving the pressing plate to vibrate in the horizontal direction; the scattering device comprises a second driving assembly and a spreading machine; the second driving assembly is arranged on the outer side of a side wall, which has the same extending direction, on the pressing plate, and is used for driving the spreading machine to move back and forth along the extending direction of the pressing plate; a movement track line of the spreading machine is parallel to the central line of the pressing plate, and the movement track line and the central line are located on the same vertical plane. By adopting the spreading device disclosed by the invention, automatic spreading is realized and the operation is convenient; the uniformity of spreading materials can be effectively ensured, the spreading time is shortened and the construction efficiency is improved; the spreading device is suitable for large-batch production, application and popularization.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a spreading device for pouring composite road surfaces. Background technique [0002] Pour-in composite pavement is an effective means to solve the road rutting problem. By pouring cement mortar as the main component into the matrix mixture with a porosity of 22%-28%, the stiffness and anti-rutting performance of the pavement can be greatly improved. However, compared with ordinary asphalt pavement, the construction process of poured composite pavement is complicated, and the on-site machinery cannot meet the large-scale construction, resulting in low efficiency of pavement construction. [0003] The construction of poured composite pavement mainly includes three links: base asphalt mixture surface layer construction, grouting construction and surface treatment, and the construction procedures of each link are relatively independent. In the grouting construc...
