A Combined Pneumatic Precast Concrete Pavement Laying Method

Abstract

The invention discloses a combined pneumatic prefabricated concrete pavement laying method, which belongs to the field of road construction. A combined pneumatic precast concrete pavement laying method can firstly inflate the interior of the pneumatic soft groove frame to adjust The orderliness of multiple concrete bricks improves the flatness of the pavement, and then pours fine stone concrete into it. On the one hand, the fine stone concrete gradually covers the skeleton gill net, so that it can be placed between two concrete bricks. A keel is formed in the connecting layer of the connecting layer, thereby increasing the strength of the connecting layer. With the function of the fiber connecting rod, the possibility of water seepage between the two concrete bricks is further reduced. On the other hand, the waterproof ball is pierced by the skeleton gill net, and the inside The waterproof coating and fine stone concrete together form a connecting layer between two concrete bricks. Compared with the existing technology, only the surface is waterproofed, which significantly improves the impermeability of the pavement, thereby significantly reducing the damage speed of the pavement .

Description

technical field [0001] The invention relates to the field of road surface construction, and more specifically relates to a combined pneumatic precast concrete pavement laying method. Background technique [0002] The concrete prefabricated slabs are made in the factory, and the pavement paved on site after transported to the construction site is a prefabricated (combined) concrete pavement. Prefabricated concrete slabs are generally made into squares or rectangles with a side length of 1 to 2 meters, and can also be made into hexagons with a side length of 1.2 meters and a thickness of 12 to 18 centimeters; they can also be made into a width of 3.5 meters and a length of 3 to 6 meters. Large plates, but need to have the corresponding transport and hoisting equipment to cooperate. The edges and corners of the slab can be equipped with steel bars, and steel mesh can also be arranged on the entire slab. In order to improve the quality of concrete, processes such as prestressi...

Problems solved by technology

Therefore, it is more suitable for parking stations and port terminals, but it has many joints and poor integrity, so it is rarely used on highways and urban roads

[0003] In the prior art, when laying prefabricated concrete bricks, although the connection between two adjacent concrete bricks is relatively tight just after the laying is completed, the bricks are prone to loosening as time goes on. It is very easy to affect the appearance of the road surface, as well as the load-bearing capacity of the road surface, and even cause the bricks to break. Moisture is easy to cause erosion to the overall road surface and accelerate the damage of the road surface
