[0002] The slag slab of the front shield of the dual-mode shield machine and the supporting device for preventing water accumulation are installed on the front shield soil bin and the screw machine mounting seat of the dual-mode shield machine.

[0003] When the dual-mode shield machine is switched from earth pressure mode to TBM mode, the hard rock strata are crushed by the cutter disc and accumulated in the soil bin in a loose state. As the cutter disc rotates, the gravel soil is scraped from the bottom of the soil bin to a higher place and enters the main machine conveyor through the front shield slag chute, thereby realizing the transportation of the gravel soil. The groundwater seeping out of the rock strata is transported out through the screw machine mounting seat and the external transmission equipment. However, this dual-mode shield machine has the following defects: the gravel soil is crushed by the cutter disc and accumulated at the bottom of the front shield soil bin and the screw machine mounting seat, making it difficult to discharge the accumulated water in the front shield soil bin, and temporary manpower and material resources are required.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1 As shown, the present invention provides a double-mode shield machine front shield anti-water accumulation device, which is installed in the soil bin 10 of the double-mode shield machine front shield 1. The double-mode shield machine front shield anti-water accumulation device includes a slag plate 2, a support plate 3, a first sealing plate 4, a screw machine mounting seat 5, a second sealing plate 6, a water supply interface 7 and a sealing ring 8.

[0018] The slag plate 2 is provided with a plurality of water leakage holes 20, and the opposite ends of the slag plate 2 are fixed to the front shield 1, and a water slag channel 21 is formed between the slag plate 2 and the front shield 1. Specifically, the slag plate 2 and the front shield 1 are fixed by welding, and the slag plate 2 is bent to form a water slag channel 21 between the slag plate 2 and the front shield 1. The slag plate 2 can prevent the accumulation of gravel at the bottom of the soil bin 10 and in the screw machine mounting seat 5. The slag plate 2 is provided with the water leakage holes 20 to separate the gravel soil from the water. It is further explained that the slag plate 2 is made of metal materials such as iron and stainless steel.

[0019] The support plate 3 is received in the slag channel 21 and fixed to the slag plate 2 and the front shield 1 to support the slag plate 2. Specifically, the support plate 3 is fixed to the front shield 1 and the slag plate 2 by welding. There can be multiple support plates 3, and adjacent support plates 3 are arranged at a certain distance to prevent the slag plate 2 from being squeezed and collapsed by gravel soil.

[0020] It should be further explained that, in addition to the welding fixation method, the front shield 1, the slag plate 2 and the support plate 3 can also be assembled and connected. In addition, the number of the above three is not limited to the number shown in the figure, and can be set according to actual needs.

[0021] The first sealing plate 4 is installed at an open end of the water-slag channel 21 and fixed to the slag plate 2 and the front shield 1. Specifically, the first sealing plate 4 is fixed to the front shield 1 and the slag plate 2 by welding. It should be further explained that the first sealing plate 4 has two pieces, and the other first sealing plate 4 is installed at the other open end of the water-slag channel 21. The first sealing plate 4 is used to isolate the slag and gravel soil.

[0022] The screw machine mounting seat 5 is hollow and fixed to the front shield 1 and communicated with the water-slag channel 21 for conveying water to the outside.
