Located in the middle of the inverted trapezoidal long gap 103, the two sides of the long foam rod 104 are in contact with the outer sides of the two adjacent upper wing plates 102 on the single T-board 101 arranged in parallel; a cement mortar part 105 is provided in the inverted trapezoidal long gap 103, and the cement mortar part 105 is located above the long foam rod 104, and a foaming filler 106 is provided in the inverted trapezoidal long gap 103; a steel plate 107 is provided on the upper wing plate 102 on the single T-board 101, and the steel plate 107 is close to the cement mortar part 105.
[0030] A reinforced concrete laminated layer 108 is provided on the upper side of the upper wing plates 102 on the two adjacently arranged single T plates 101;
[0031] The long foam rod 104 is a polyethylene foam rod; waterproof and heat-insulating: the polyethylene foam rod has good waterproof and heat-insulating properties. In projects such as concrete, it can be used to fill gaps to prevent moisture from penetrating through these gaps, ensuring the dryness and heat-insulating effect of the project. High wear resistance and impact strength: this allows the polyethylene foam rod to withstand certain wear and impact after filling the gap, maintaining the sealing and stability of the gap. Good self-lubrication and extremely low water absorption: these two characteristics allow the polyethylene foam rod to enter the gap more smoothly when filling the gap, and will not cause performance degradation due to water absorption during use. Chemically stable, light and soft: these characteristics allow the polyethylene foam rod to adapt to various complex gap shapes while maintaining the stability of its chemical properties and will not react adversely with surrounding materials. Good heat preservation, heat insulation and resilience: these characteristics of the polyethylene foam rod enable it to effectively maintain the temperature stability of the gap after filling the gap, and have good resilience and can adapt to slight changes in the gap. Chemical and Aging Resistance: This allows the polyethylene foam rod to resist chemical corrosion and aging during long-term use, maintaining its performance and lifespan.
[0032] The foaming filler 106 is a polyurethane foaming agent. Sealing and plugging leaks: The polyurethane foaming agent forms foams in the gaps. These foams have strong adhesion and can effectively seal the gaps to prevent gas, moisture or other external substances from penetrating through the gaps, thereby playing a role in sealing and plugging leaks. Bonding and fixing: The foam formed by the foaming agent not only fills the gaps, but also can firmly bond with the materials on both sides of the gaps to provide stable support and fixing effects. This is very important for building structures, decorative materials, etc. that need to be connected or fixed. Sound absorption and shock absorption: Foam materials have certain sound absorption and shock absorption capabilities. After filling the gaps, it can reduce the spread of noise, improve the acoustic performance of the building, and at the same time reduce the impact of vibration on the building to a certain extent. Strong durability: The foam formed by the polyurethane foaming agent has a service life of not less than ten years under normal conditions of use. This means that it can maintain stable performance over a long period of time and provide lasting protection for the building.
[0033] The web 109 on the single T-plate 101 is arranged vertically.
[0034] The main functions of the steel plate in the double T-plate of the bridge include the following: Enhance structural strength: As an important structural component in the double T-plate, the steel plate can significantly increase the overall strength of the double T-plate. Through close integration with concrete, the steel plate can effectively improve the bearing capacity of the bridge and ensure the stability and safety of the bridge under various loads; Improve durability: The steel plate has high corrosion resistance and durability, and can maintain its performance under harsh environmental conditions. The use of steel plates in the double T-plate of the bridge can extend the service life of the bridge and reduce the frequency of maintenance and replacement; Optimize construction efficiency: The prefabrication and standardized production of steel plates can greatly improve construction efficiency. In bridge construction, the use of prefabricated double T-plates (including steel plates) can shorten the construction period, reduce on-site pouring and maintenance time, and thus realize the rapidity of the project; Improve seismic performance: The steel plate has good ductility and toughness, and can absorb and disperse energy in natural disasters such as earthquakes.

[0041] Finally, a reinforced concrete laminate layer 108 is provided on the upper side of the upper wing plates 102 of the two adjacent and parallel single T plates 101. This laminate layer can further enhance the overall rigidity and bearing capacity of the bridge body, and ensure the stability and safety of the bridge under various loads.
[0042] In summary, this new type of double-T plate bridge body achieves high strength, high stability, high durability and good seismic resistance through ingenious structural design and high-quality material selection, providing strong support for modern bridge construction.
[0043] High construction efficiency: The design of the new double-T plate bridge takes into account the convenience of construction, such as the use of standardized production and on-site assembly and installation, which makes the construction process more efficient and faster, thereby shortening the construction period and reducing construction costs.
