Description

Technical Field

[0001] This utility model relates to the field of high-speed railway infrastructure technology, specifically to a high-speed railway box-type roadbed construction equipment. Background Technology

[0002] In the construction of high-speed railways, the stability and durability of the roadbed are of paramount importance. As the supporting structure of high-speed railways, the roadbed not only needs to bear the train load, but also needs to resist various influencing factors in the natural environment, such as water erosion and soil settlement. Traditional roadbed construction methods often cannot fully meet the high requirements of high-speed railways for stability and durability. Especially in areas with complex geological conditions or high rainfall, the stability and drainage performance of the roadbed have become urgent problems to be solved.

[0003] However, existing technologies have the following problems in practical use:

[0004] In actual use, the load-bearing capacity and deformation resistance of the new invention are insufficient. Existing equipment has limitations in terms of the load-bearing capacity and deformation resistance of the roadbed. It lacks an effective combination of geogrid and reinforcing piles, which makes it difficult for the roadbed to withstand the high load of high-speed railway trains. It is prone to settlement and deformation, which affects the stable operation of high-speed railways. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a high-speed railway box-type subgrade construction equipment, which has the following beneficial effects:

[0019] This high-speed railway box girder construction equipment, through the coordinated arrangement of drainage grooves, reinforcing piles, and pre-embedded reinforcing frames, enhances the stability of the device during use. The drainage grooves designed on both sides of the box girder, along with the matching drainage pipes and leak pipes, form an efficient drainage system that can promptly remove surface water and groundwater from the roadbed, reducing moisture erosion of the roadbed materials, keeping the roadbed structure dry and stable, and extending its service life. By fixing geogrids and reinforcing piles at the bottom of the box girder, the overall bearing capacity and deformation resistance of the roadbed are effectively enhanced. The geogrids can disperse soil pressure and prevent soil settlement, while the reinforcing piles penetrate deep into the ground, providing stable support and ensuring the safety and stability of high-speed railway operation.
