[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 , Figure 2 shown, the support structure device for the excavation of the slopes at the inlet and outlet of the water conveyance tunnel in this embodiment includes a slope top connecting plate 1, a slope surface support plate 2, a slope surface fixing member 3, and a slope bottom cross-section support plate 4. The slope top connecting plate 1 is vertically arranged at the slope top of the slope and is connected to the baffle at the slope top of the slope. The slope surface support plate 2 is inclinedly laid on the slope surface, and the upper end is connected to the lower end of the slope top connecting plate 1. The slope surface fixing member 3 is arranged on the slope surface support plate 2, penetrates through the slope surface support plate 2 and is inserted into the slope surface. The slope bottom cross-section support plate 4 is vertically blocked outside the slope bottom cross-section of the slope, and the upper end is connected to the slope surface support plate 2.

[0027] Specifically, as Figure 3 shown, in this embodiment, a plurality of slope top connecting plates 1 are continuously arranged on the slope top of the slopes at the inlet and outlet of the water conveyance tunnel. Connection fixing holes 12 are opened at both ends of the slope top connecting plate 1. A connection fixing plate 13 is arranged between two adjacent slope top connecting plates 1. Through holes corresponding to the connection fixing holes 12 are opened at both ends of the connection fixing plate 13. Slope top fixing members 14 are inserted into the connection fixing holes 12 of the slope top connecting plate 1. The slope top fixing members 14 on two adjacent slope top connecting plates 1 that are close to each other penetrate through the connection fixing plate 13 and the slope top connecting plate 1 and are inserted into the baffle at the slope top of the slope. The slope top fixing member 14 on the outermost slope top connecting plate 1 that is far from the adjacent slope top connecting plate 1 penetrates through the slope top connecting plate 1 and is inserted into the baffle at the slope top of the slope, thereby fixing the slope top connecting plate 1 at the slope top of the slope and connecting the adjacent slope top connecting plates 1, so as to increase the overall stability of the support structure.

[0028] Specifically, the slope top fixing member 14 can be selected as an anchor rod, a fixing cone, an expansion bolt, etc. according to the actual situation. The slope top fixing member 14 in this embodiment is an anchor rod, and barbs are arranged on the anchor rod, which is suitable for the baffle of the original soil structure.

[0029] In this embodiment, in combination with Figure 4 and Figure 5As shown in the figure, the slope top connecting plate 1 is hinged to the slope surface supporting plate 2. A support rod 5 is arranged on one side of the slope top connecting plate 1 close to the slope surface supporting plate 2. One end of the support rod 5 is hinged to the slope surface supporting plate 2, and an insertion rod 6 is arranged at the other end. A sleeve 7 is arranged at the upper end of the slope surface fixing part 3, and the insertion rod 6 is detachably inserted into the sleeve 7. Specifically, a spherical hinge seat 8 is fixed on one side of the slope top connecting plate 1 close to the slope surface supporting plate 2, and a spherical rod 9 adapted to the spherical hinge seat 8 is fixed at one end of the support rod 5 close to the slope top connecting plate 1. One end of the support rod 5 far from the slope top connecting plate 1 is fixedly connected with a triangular support 10, and an insertion rod 6 is arranged on each leg of the triangular support 10. A slope surface fixing part 3 adapted to each insertion rod 6 is arranged on the slope surface supporting plate 2. The slope surface fixing part 3 is an anchor rod with barbs arranged on its circumferential side.

[0030] A through hole corresponding to the slope surface fixing part 3 is arranged on the slope surface supporting plate 2. During installation, first insert the insertion rod 6 onto the sleeve 7 of the corresponding slope surface fixing part 3, and then simultaneously insert the three slope surface fixing parts 3 through the through holes on the slope surface supporting plate 2 and into the slope surface, so as to fix the slope surface supporting plate 2 on the slope surface to support the slope surface.

[0031] In this embodiment, several bottom slope cross-section supporting plates 4 are arranged in a stepped shape from top to bottom in sequence. Part of the adjacent two bottom slope cross-section supporting plates 4 overlaps, and the bottom slope cross-section supporting plate 4 located below is pressed on the outside of the bottom slope cross-section supporting plate 4 located above, and the overlapping parts of the adjacent two bottom slope cross-section supporting plates 4 are bolted. Specifically, between the adjacent two bottom slope cross-section supporting plates 4, a plurality of bolts are fixed at the bottom of the side of the bottom slope cross-section supporting plate 4 located above far from the slope protection, through holes corresponding to the bolts are opened at the top of the side of the bottom slope cross-section supporting plate 4 located below far from the slope protection, and the bolts penetrate through the through holes and are screwed with nuts.

[0032] During actual installation, the installation quantity of the bottom slope cross-section supporting plates 4 gradually increases with the increase of the excavation depth. In another embodiment, as Figure 6 shown, when the bottom slope excavation depth is not deep, only one layer of bottom slope cross-section supporting plates 4 can be set.

[0033] In this embodiment, a connecting folding plate 11 is arranged on the outside of the mutually close ends of the slope surface supporting plate 2 and the topmost bottom slope cross-section supporting plate 4. The connecting folding plate 11 can be formed by bending a flat plate, or can be formed by welding two flat plates. The included angle of the connecting folding plate 11 is adapted to the bottom of the slope surface. The two sides of the connecting folding plate 11 are bolted to the slope surface supporting plate 2 and the topmost bottom slope cross-section supporting plate 4 respectively. Similarly, screw rods are fixed on the slope surface supporting plate 2 and the topmost bottom slope cross-section supporting plate 4, and through holes are opened on the connecting folding plate 11.

[0034] The working principle of the support structure device for the excavation of the slopes at the inlet and outlet of the water conveyance tunnel in this embodiment is:

[0035] The slope-top connecting plate 1 is arranged at the slope top of the water conveyance tunnel inlet and outlet slopes and is connected to the baffle at the slope top. On the one hand, it fixes the support structure device, and on the other hand, it also supports the baffle at the slope top. The slope surface support plate 2 is laid on the slope surface, the upper end is connected to the slope-top connecting plate 1, and is fixed on the slope surface through the slope surface fixing piece 3, so as to support the inclined slope surface. The bottom-section support plate 4 of the slope supports the bottom section of the slope to prevent the section from collapsing during the excavation of the slope bottom. The slope-top connecting plate 1, the slope surface support plate 2 and the bottom-section support plate 4 of the slope provide all-round support for the water conveyance tunnel inlet and outlet slopes, thereby effectively supporting the water conveyance tunnel inlet and outlet slopes and maintaining the stability of the water conveyance tunnel inlet and outlet slopes.
