Example Embodiment

[0055] Example 1:

[0056] See Figure 1 to Figure 19 .

[0057] Such as figure 1 with figure 2 As shown, the super-large diameter cutter head provided by the embodiment of the present invention includes a center block 11 and a plurality of cutter head side blocks arranged on the periphery of the center block 11. The cutter head side block includes the main cutter head side blocks 12 (table The hollow main beam in 1) and the auxiliary cutter head edge block 13 (the auxiliary beam in Table 1), the main cutter head edge block 12 and the auxiliary cutter head edge block 13 each have six. Because the super-large diameter cutter head is made in blocks, it is convenient to transport from the production site to the construction site. Then the center block 11, the main cutter head side block 12 and the auxiliary cutter head side block 13 are connected and positioned by bolts and positioning pins, and finally welded As a whole, after welding, remove the bolts and positioning pins.

Abstract

The invention discloses a configuration method for super-large-diameter cutter head and cutter thereof, which solve the technical problems of inconvenience to transfer the super-large-diameter shieldcutter head and change the cutter in the prior art. The super-large diameter cutter head comprises a central block and a plurality of cutter head edge blocks arranged on the periphery of the central block, wherein the central block and the cutter head edge blocks are assembled into the cutter head, the central block and a main cutter head edge block are hollow box bodies, a cutter head opening isformed between the adjacent main cutter head edge block and an auxiliary cutter head edge block, the opening of the cutter head is connected with a muddy water bin behind the cutter head, and a plurality of normal pressure replaceable cutters are arranged on the front panels of the central block and the main cutter head edge block. The super-large-diameter cutter head is characterized in that theproblem of inconvenience to transport the super-large-diameter shield cutter head is effectively solved, and the center block and the inner part of the main cutter head edge block are separated from the front palm surface of the cutter head and the rear muddy water bin, the front palm surface of the cutter head and the rear muddy water bin are in a high-pressure environment, while the center blockand the main cutter head edge block are in a normal pressure environment, accordingly the cutter is convenient to be replaced.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to an ultra-large-diameter cutter head and a method for arranging the cutter. Background technique [0002] At present, the construction technology of shield tunnels with a diameter of less than 12m is gradually becoming mature, but the construction technology of super-large-diameter shield tunnels in China is still in its infancy. Super-large-diameter shield tunnels generally refer to shield tunnels with a diameter of more than 14m, which are generally used for highways. , rail transit and other construction projects can meet the needs of double-deck 4 / 6 lanes or single-deck 3-lane, and will have a strong traffic capacity after completion. [0003] Shield equipment is the key to the success of a super-large-diameter shield tunnel project. Due to the cross-sectional size and structural top-covering soil requirements of super-large-diameter shield tunnels, it is inevitable to...
