The construction environment of bridge construction is special, so it is different from ordinary road construction. It needs to be constructed while driving in the air. Not only is it difficult to construct, but also requires high performance. Nowadays, bridge construction is not only to be strong but also to ensure the aesthetics in appearance.

 

Due to design problems, the construction period of bridge construction projects is tight and the tasks are heavier. The following problems are prone to occur:


The problem of material selection. Generally, concrete is used most in bridge construction, and sand is the most used material in concrete. In the mixing station, for sand with high stone content, pebbles are not deducted, and the sand speed, concrete and workability are directly reduced. The deteriorated sand and gravel are filled on part of the gravel, and the strength of the concrete is reduced.


In addition, it is easy to collapse during concrete construction. As far as the quality of the structure is concerned, under the premise of ensuring the smooth construction, the smaller the collapse degree, the better. If the construction cannot be guaranteed, the quality and durability cannot be guaranteed. In the engineering taking pile foundation as an example, the pile foundation strength is generally low, the powder content is small, the settlement amount is large, broken piles and waste piles occur frequently, the bridge abutment sinks, and the bridge head jumps and so on.

 

In order to solve the problem of bridge collapse, Geogrid for bridge construction has gradually deepened research. Because the geogrid is a mesh structure, it can evenly distribute a part of the force to the surroundings in the surface layer, effectively reducing the difference. Geogrid for bridge construction improves the support stiffness of the subgrade filler by strengthening the role of the subgrade filler, reduces the vertical stress of the subgrade; effectively reduces the uneven settlement of the bridge abutment and subgrade; improves the stability of the subgrade and solves the unevenness the problem of settlement.
