The invention provides a large-diameter slurry shield dry receiving device, which relates to the technical field of shield tunneling, and adopts the scheme that the large-diameter slurry shield dry receiving device comprises a concrete base and a steel base, the concrete base is located in front of the steel base, the length of the concrete base in the tunneling direction is 1-3 meters, the length of the steel base in the tunneling direction is 13-17 meters, and the steel base is located in front of the concrete base. An arc-shaped receiving groove is formed in the concrete base, the steel base comprises side supporting structures and a connecting bottom frame structure, the connecting bottom frame structure is located at the bottoms of the side supporting structures, the two side supporting structures are connected through the connecting bottom frame structure, and the upper portions of the side supporting structures support the shield tunneling machine. The concrete base and the steel base are provided with axial gradients for receiving the shield tunneling machine so as to ensure that the cutterhead can smoothly step on the bases, and the axis of the steel base is lower than that of concrete. After the shield tunneling machine is disassembled, the time for disassembling the concrete base and the steel base is short, and the construction period is greatly shortened.
Description
technical field [0001] The invention relates to the technical field of shields, in particular to a dry receiving device for large-diameter mud-water shields. Background technique [0002] At present, domestic large-diameter shield machines mostly use mud-water balance shield machines. The receiving methods are divided into two types: dry receiving and underwater receiving. With the improvement of shield technology, dry receiving is more convenient and faster than the underwater receiving method. , greatly shortening the construction period, and has gradually become the main way of receiving large-diameter shields. [0003] The shield receiving base is to meet the receiving requirements of the shield, and a platform is set at the bottom of the working well to support the shield machine during the receiving process. At present, most of them are single concrete base or steel base. [0004] Using a single concrete base, after the dismantling of the shield machine is completed,...
