Similarly, in other embodiments of the present invention, when the tunnel 120 penetrates through one masonry course 110, the plurality of steel reinforcement gravel cage units 111 of the masonry course 110 where the tunnel 120 is located are all formed with channels, and the plurality of steel reinforcement gravel cage units 111 formed with channels are sequentially connected in a direction from one bank to the other bank of the deep-cut canyon 10; the plurality of channels are in turn connected and form a tunnel 120. Since the tunnel 120 penetrates through one masonry layer 110, a corresponding channel is formed in each reinforcement gravel cage unit 111 according to the position of the tunnel 120 formed by each reinforcement gravel cage unit 111 correspondingly.
It should be noted that in this embodiment, the tunnel 120 may extend along the arcuate contour of the masonry layer 110 in which it is located when the tunnel 120 is formed. In other embodiments of the present invention, the tunnel 120 may also be a through tunnel 120.
Further, referring to fig. 1 to 7, in the present embodiment, in order to improve the waterproof property of the tunnel 120 and the aesthetic appearance of the tunnel 120, the deep cutting canyon guard structure 100 further includes a waterproof liner 122 laid on the inner circumferential surface of the tunnel 120. The waterproof packing 122 may be formed by spraying concrete, or a corrugated plate or a basalt fiber plate may be laid.
Based on the above, referring to fig. 1 to 7, the present invention further provides a method for constructing a deep-cut canyon guard structure 100, which includes:
referring to fig. 2, at least one row of reinforcement cage units 111 of the same masonry course 110 is constructed from both banks of the deep-cut canyon 10 in the opposite direction, respectively;
constructing the rest rows of reinforced gravel cage units 111 of the same masonry layer 110 to one side or two sides of the first working platform along the extending direction of the deep-cut canyon 10 by using the constructed at least one row of reinforced gravel cage units 111 as the first working platform;
referring to fig. 3, the rest of the masonry courses 110 of the deep canyon guard structure 100 are constructed upward in the vertical direction with the constructed masonry course 110 as a second working platform;
the direction in which the reinforcement cage units 111 are arranged in a row is a direction extending from one bank of the deep-cut canyon 10 to the opposite bank.
By the construction mode, the construction steps can be simplified, and the auxiliary engineering machinery required for constructing the deep canyon protective structure 100 is reduced, so that the construction cost can be reduced while the construction efficiency is improved; in addition, the safety factor of constructors can be improved by the mode.
It should be noted that, in the present embodiment, the remaining rows of rebar debris cage units 111 of the same masonry course 110 and the remaining masonry courses 110 of the deep canyon shelter structure 100 may be constructed simultaneously, that is, the first work platform and the second work platform may share at least one row of the constructed rebar debris cage units 111.
In conclusion, the deep-cut canyon guard structure 100 constructed by the method for constructing the deep-cut canyon guard structure provided by the invention can resist geological disasters such as rockfall, landslide and the like, so that the rockfall, landslide and the river channel 20 are blocked, and the situation that the rockfall or the soil body of the landslide blocks the river channel 20 as a blocking object can be avoided, so that a barrier lake can be avoided from being formed, and flood disasters caused by dam break of the barrier lake can be avoided.
When the collapsed rock or the soil body of the landslide falls onto the deep-cut canyon guard structure 100, the stress of the deep-cut canyon guard structure 100 is transferred to both sides of the deep-cut canyon guard structure 100 and the deep-cut canyon 10 because the deep-cut canyon guard structure 100 is arched; therefore, the deep-cut canyon protection structure 100 is arched, so that the capability of resisting geological disasters such as rockfall, landslide and the like can be improved, the rock or landslide soil body which falls on the deep-cut canyon protection structure 100 can increase the gravity of the deep-cut canyon protection structure 100, and the stability of the connection position of the deep-cut canyon protection structure 100 and the deep-cut canyon 10 on both sides can be increased; that is, the deep-cut canyon guard structure 100 has a certain self-growth ability, and can increase its own weight by a rock or a landslide soil body, thereby increasing its own structural stability.
In addition, in the process of maintenance of the deep cutting canyon guard structure 100, since the rock or landslide soil mass that falls onto the deep cutting canyon guard structure 100 can increase the gravity of the deep cutting canyon guard structure 100, thereby increasing the stability of the connection between the deep cutting canyon guard structure 100 and the deep cutting canyon 10, the rock or landslide soil mass that falls onto the deep cutting canyon guard structure 100 does not need to be cleaned in real time, and when the rock or landslide soil mass on the deep cutting canyon guard structure 100 is cleaned, the rock or landslide soil mass on the deep cutting canyon guard structure 100 only needs to be dispersed in the deep cutting canyon guard structure 100, so as to prevent the rock or landslide soil mass from being concentrated at a certain position on the deep cutting canyon guard structure 100, thereby reducing the maintenance cost.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
