Abstract

The invention discloses an efficient large-diameter mud water shield tunneling machine transportation method for synchronous construction of a high box culvert and a device of the method. According tothe transportation method, the high box culvert in a large-diameter tunnel and spaces on both sides of the high box culvert are utilized, a vehicle passing device is adopted for expanding the space of the rear portion of a shield tunneling machine, different transportation vehicles can be contained at the same time, and passing and turning of the vehicles are realized. Therefore, a vehicle passing platform device is designed. The vehicle passing platform device mainly comprises vehicle passing platform steel frames, inner side small rollers, outer side bottom large rollers, outer side middlelarge rollers, pedals, drag hydraulic cylinders, shield tail side drag connection frames, drag connection pins, steel frame connection plates, vehicle passing platform side drag connection frames andsteel frame connection rods. The rollers different in size are installed on the steel frames of a vehicle passing platform. The drag hydraulic cylinders are welded to the front end of the vehicle passing platform. According to the method and the device, the speed of supplying materials required for construction is greatly increased, and the work efficiency of the shield tunneling machine is improved.

Description

technical field [0001] The invention belongs to the field of shield tunnel construction, and in particular relates to a large-diameter slurry shield machine transportation method for synchronous construction of high box culverts. Background technique [0002] With the continuous acceleration of urbanization in my country and the rapid growth of urban population, the development of underground space is imminent. Slurry shield machine is the most commonly used underground tunnel excavation machine under the condition of crossing rivers and seas with rich water. When large-diameter shield construction is used, the middle box culvert is generally precast and assembled, and the side box culverts are simultaneously cast in-situ during the box culvert construction process. After the initial trial operation of the shield machine, the speed began to increase. With the continuous excavation of the tunnel, the transportation distance of the materials required for the excavation also i...
