[0031] Specifically, the body unit 10 comprises symmetrically arranged inner plates 11 and outer plates 12, a first side plate 13 is connected between the first sides of the inner plates 11 and the outer plates 12, a second side plate 14 is connected between the second sides of the inner plates 11 and the outer plates 12, the locking groove is arranged on the first side plate 13, and the locking strip is arranged on the second side plate 14. In the embodiment, the locking groove is arranged at the connection between the first side plate 13 and each of the inner plates 11 and the outer plates 12, and the locking strip is arranged at the connection between the second side plate 14 and each of the inner plates 11 and the outer plates 12. Adjacent body units 10 are connected by the matching locking of the locking groove and the locking strip, and are relatively fixed in the horizontal direction but can slide relative to each other in the vertical direction. The invention can realize the segmented sinking of the end plate body 1 by using the above-mentioned locking structure. Further, the inner plates 11, the outer plates 12, the first side plate 13 and the second side plate 14 are horizontally and sealingly connected with a mounting plate, and the mounting plate is provided with mounting holes for connecting the excavation heads. In the embodiment, the excavation heads 2 can adopt the head form of a pipe jacking machine, and each excavation head 2 is clamped in the corresponding mounting hole in the vertical direction. Figure 3 In order to avoid too many body units 10 affecting the sinking efficiency, a plurality of excavation heads 2 can be installed on each body unit 10, and a plurality of mounting holes corresponding to the plurality of excavation heads 2 are arranged on the mounting plate. In addition, in order to facilitate the control of the excavation heads 2, each excavation head 2 is independently controlled by an external controller. Specifically, the side of the mounting plate opposite to the sinking surface is provided with a driving device for driving the excavation heads 2 and a sludge circulating system for flushing and pumping silt at the excavation heads 2, and the driving device and the sludge circulating system are connected with the external controller. The controller can be a general control system arranged on the deck.
