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

Embodiment 1

[0042] see figure 1 , a combined pneumatic type precast concrete pavement laying method, comprising the following steps:

[0043] S1. First, clean the road surface to be constructed, excavate trenches, lay the roadbed, and level the roadbed after laying;

[0044] S2. Lay the pneumatic soft trough frame on the roadbed, and set the limit plate at the edge of the pneumatic soft trough frame, and the limit plate is fixed and buried on the roadbed;

[0045] S3, coating the concrete layer on the bottom of the pneumatic soft trough frame, and then laying the prefabricated concrete bricks on the pneumatic soft trough frame one by one;

[0046] S4. Inflate the pneumatic soft groove frame, adjust the position of two adjacent concrete bricks and the flatness of the upper surface;

[0047] S5. After the adjustment, fill the inside of the pneumatic soft trough with fine stone concrete again until the pneumatic soft trough is fully stretched, and multiple concrete bricks are closely conne...

Abstract

The invention discloses a combined pneumatic precast concrete pavement paving method, and belongs to the field of pavement construction. The combined pneumatic precast concrete pavement paving methodcomprises the following steps: arranging a pneumatic soft groove frame, inflating the pneumatic soft groove frame to adjust the uniformity among a plurality of concrete bricks and improve the flatnessof the pavement, and then injecting fine aggregate concrete into concrete bricks. On one hand, a framework gill net is gradually covered with the fine aggregate concrete, so that a keel is formed ina connecting layer between the two concrete bricks, the strength of the connecting layer is improved, and the possibility of water seepage between the two concrete bricks is further reduced under theaction of a fiber connecting rod; and on the other hand, waterproof balls are punctured by the skeleton gill net, and a waterproof coating and the fine aggregate concrete in the waterproof balls formthe connecting layer between the two concrete bricks together, so that compared with the prior art, the method has the advantages that only the surface is subjected to waterproof treatment, the impermeability of the pavement is remarkably improved, and the damage speed of the pavement is remarkably reduced.

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...
