Prestressed cement concrete pavement sliding layer paving device

Abstract

The invention relates to the technical field of cement concrete pavement paving devices and discloses a prestressed cement concrete pavement sliding layer paving device. The device comprises an shaft bracket, a scraping plate and two height adjusting frames, wherein the height adjusting frames are fixedly connected with the scraping plate, and each height adjusting frame comprises a top surface, a bottom surface, a left side surface and a right side surface with an opening; a bolt is welded in the middle point of the shaft bracket; and the other end of the bolt extends out of the opening and is connected with a nut. The left side surface of the scraping plate is fixedly connected with the shaft bracket, and the height adjusting frames move up and down to drive the scraping plate to move, thereby adjusting the height above the ground of the scraping plate; and scale values, pointed by pointers, of height scale bars are read to determine a preset pavement height, thereby paving a uniform pavement sliding layer the pavement height of which can meet preset requirements.

Description

technical field [0001] The invention relates to the technical field of cement concrete pavement laying devices, and more particularly, relates to a prestressed cement concrete pavement sliding layer laying device. Background technique [0002] "To develop the economy, the road must go first." With the growth of the global economy, the transportation industry in all countries in the world has developed by leaps and bounds. Constructing "safe, comfortable, environmentally friendly and economical" long-lived pavements has become the primary task for traffic workers. Ordinary cement concrete pavement has the advantages of wide source of raw materials, low price, long service life, and low maintenance cost in the later period. It will be the best choice for pavement development in the future. However, the expansion joints and cracks of ordinary cement concrete pavement are the weak links of stress, so they are often damaged easily. Mud pumping and hollowing out of the bottom of...

Problems solved by technology

[0005] At present, there is no special sliding layer laying device at home and abroad, and it is generally laid by manual use of shovels.

Manual use of shovel laying can neither meet the thickness requirements nor ensure the laying uniformity of the sliding layer. It is far from meeting the laying requirements of the sliding layer, which seriously affects the function of the sliding layer.
