Description

Technical Field

[0001] The utility model relates to a construction device, in particular to a pavement base cloth laying device. Background Art

[0002] During road construction, base cloths with different functions are laid according to actual needs. For example, a layer of polyester fiber cloth for roads is laid between the lower layer and the surface layer of the asphalt pavement structure, which can reduce and delay the overlap of new and old pavements and the cracking of the pavement caused by the semi-rigid base, and prevent the damage of the base caused by water intrusion.

[0003] Regarding the construction methods of various road base cloths, the most traditional method is to allocate 6 - 8 people according to the width of the base cloth, and lay the base cloth, such as polyester fiberglass cloth, after fully unfolding it. When the wind is strong, additional personnel need to be added or the construction needs to be stopped for this laying method.

[0004] Chinese Patent Document CN 213015433 U (Application No. 202020920192.9) discloses a tool for laying geotextiles, including a laying roller, a bracket, and a push rod. The laying roller includes a semi-cylindrical barrel and a non-semi-cylindrical barrel hinged through a connecting member. The bracket includes two side frames connected to both sides of the semi-cylindrical barrel and a connecting rod connecting the two side frames. The push rod is fixedly connected to the middle of the connecting rod. A limiting member is connected between one end of the non-semi-cylindrical barrel far from the connecting member and the side frame. Compared with the method of fully unfolding and laying by manual labor, using this laying tool can save the number of people for laying, but it is still relatively laborious.

[0005] Chinese Patent Document CN 216379043 U (Application No. 202122737048.9) discloses another laying machine, including a laying machine main body and an anti-cracking base cloth laying mechanism. The anti-cracking base cloth laying mechanism includes a support frame, an anti-cracking cloth shaft, a limiting block, a fiberglass polyester cloth, a rotating shaft, and a groove. The support frame is fixedly connected to one side surface of the laying machine main body. The limiting block is fixedly connected to the support frame. A groove is opened on the top surface of the limiting block. The anti-cracking cloth shaft is inside the support frame. The rotating shaft is at the center of the anti-cracking cloth shaft. Both ends of the rotating shaft are inside the groove. The fiberglass polyester cloth is on one side at the bottom of the rolling drum. This laying machine is more labor-saving, but the purchase and use costs are relatively high. Summary of the Utility Model
