Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically a steel structure reinforcement device for pile-slab road structures. Background Technology

[0002] Pile-slab road structures are a relatively new type of highway structure. With increasing service life, they may develop defects such as cracking due to continuous structural degradation. In such cases, reinforcement is necessary to improve their load-bearing capacity or stiffness. One of the key technical issues in the maintenance of such structures is to apply simple and reliable strengthening measures comprehensively based on their performance requirements. Existing technologies for reinforcing such structures are limited; reinforcement is generally applied only in one direction, making it difficult to simultaneously reinforce both longitudinal and transverse directions.

[0003] To address the aforementioned issues, an improved steel structure reinforcement device for pile-slab road structures is now designed. Utility Model Content

[0027] Step 2: Before installing the pile cap steel shell 1, epoxy mortar needs to be applied to the surface of the pier cap 11 to ensure that the pile cap steel shell 1 and the pier cap 11 are tightly attached. Then, the pile cap steel shell 1 is fixed to the pier cap 11 using anchor bolts 2.

[0028] Step 3: Determine the beam height of the first transverse support beam 6 according to the requirements of transverse reinforcement, and match the position of the first transverse steel bracket 3.
