AI Technical Summary

Technical Problem

It is difficult for vehicles to turn around in tunnels, especially when space is limited. Traditional U-turn methods affect construction progress and pose safety risks.

Method used

A trestle bridge for vehicle U-turns in tunnels is designed, which includes a trestle bridge body, a supporting structure, a front approach bridge and a rear approach bridge. It is equipped with a U-turn device and a supporting structure, including fixed legs and movable legs. The U-turn device is used to realize vehicle steering, and the supporting structure maintains stability under different terrains.

Benefits of technology

It improves the efficiency and safety of vehicle U-turns in tunnels, ensures efficient use of roads, adapts to the balance state under different terrain conditions, expands the applicability of the trestle, and reduces waiting time through a two-way single-lane structure.

Abstract

The utility model relates to a trestle for turning around vehicles in a tunnel, which comprises a trestle main body, a supporting structure for supporting the trestle main body, a front approach bridge arranged at the front end of the trestle main body and a rear approach bridge arranged at the rear end of the trestle main body, a turning-around device is embedded on the upper surface of the trestle main body, and the supporting structure comprises a fixed supporting leg and a movable supporting leg. The fixed supporting legs are arranged at the two ends of the trestle body, the movable supporting legs are arranged in the middle of the trestle body, each of the fixed supporting legs and the movable supporting legs comprises a sleeve and an inner column arranged in the sleeve in a sleeved mode, the sleeves of the fixed supporting legs are fixedly connected with the trestle body, and the sleeves of the movable supporting legs can move in the length direction of the trestle body through walking devices. By arranging the turning device, when a vehicle needs to turn around, the vehicle can be driven onto the trestle and steered through the turning device, and passing of other vehicles is not affected, so that the use efficiency of a road is greatly improved, meanwhile, the trestle can adapt to the installation requirements of different heights, production standardization of the trestle is facilitated, and the application range of the trestle is wider.
