[0032] The bamboo-cutting type tunnel portal, as a type of tunnel portal structure, has unique appearance features and important structural attributes.

[0033] Please refer to Figures 1 to 4, A rockery waterfall structure for a bamboo-cut tunnel portal provided in an embodiment of the present utility model includes a rockery structure 10, a water-drop waterfall structure 20, a reservoir (not shown in the figure), a return pool 30, and a water circulation driving mechanism 40; wherein, the reservoir is used to collect rainwater on the top of the rockery structure 10; specifically, a suitable storage pool can be dug upstream of the top of the rockery structure 10 to collect rainwater, and the location for buffering flood in the rainy season needs to be determined according to the site conditions. To ensure that water flows out of the rockery during the dry season to meet the rockery landscape requirements.

[0034] The water-drop waterfall structure 20 is arranged on the rockery structure 10, and the rainwater in the reservoir is conveyed to the water-drop waterfall structure 20 through a first water conveyance component (not shown in the figure); the water-drop waterfall structure 20 can be pre-constructed on the rockery structure 10 or integrally formed with the rockery structure 10. The water-drop waterfall structure 20 can adopt a conventional water-drop waterfall structure 20 arranged on a rockery. The rockery structure 10 is preferably made of artificial plastic stone with the color of natural original stone gray; the first water conveyance component can adopt the form of a water pipe or a channel, and the rainwater in the reservoir can be drained by gravity to the position of the water-drop waterfall structure 20. Or a valve can also be arranged on the drain pipe, and the flow of water can be controlled by controlling the opening and closing of the valve.

[0035] The return pool 30 is arranged below the water-drop waterfall structure 20 and is used to collect the rainwater flowing down from the corresponding water-drop waterfall structure 20. The water circulation driving mechanism 40 is arranged in the return pool 30, and the water circulation driving mechanism 40 is used to convey the rainwater in the return pool 30 to the reservoir through a second water conveyance component 510.

[0036] Working process: The reservoir located on the top of the rockery structure 10 collects rainwater, which serves as the water source for the water-drop waterfall structure 20 of the rockery. During the dry season, the rainwater in the reservoir is conveyed from top to bottom through the first water conveyance component to the position of the water-drop waterfall structure 20 below. The rainwater flows through the water-drop waterfall structure 20 by gravity to form a water-drop waterfall landscape. Under the action of gravity, the water of the corresponding water-drop waterfall structure 20 flows out into the return pool 30, and then the water in the return pool 30 is sent back to the reservoir by the water circulation driving mechanism 40 to form a water circulation system, so that the water level of the return pool 30 is maintained at an appropriate height and a water-drop waterfall landscape is formed, realizing the rockery water-drop waterfall landscape of the tunnel portal by using natural rainwater, and having a good application prospect.

[0037] As a preferred embodiment, the return pool 30 includes a pool body 310 and a drain pipe 340 with a valve. One end of the drain pipe 340 communicates with the pool body 310, and the other end of the drain pipe 340 communicates with an existing tunnel drainage system (not shown in the figure).

[0038] Furthermore, the pool body 310 includes a first pool bottom surface 320 and a second pool bottom surface 330 that are stepped. The second pool bottom surface 330 is lower than the first pool bottom surface 320. The water circulation driving mechanism 40 is arranged on the second pool bottom surface 330, and the top end of the drain pipe 340 is correspondingly communicated with the second pool bottom surface 330. It should be noted that the stepped design can provide more convenient access to the pool, facilitating cleaning and maintenance. In other embodiments, those skilled in the art can also set the structure of the pool body 310 in other forms.

[0039] Working process: Combining Figure 3 , in this embodiment, a normal water level upper limit 350 and a normal water level lower limit 360 are set in the pool body 310. When the water level in the pool body 310 is higher than the normal water level upper limit 350, the drain pipe 340 can be opened to drain the excess water level in the pool body 310 (such as opening the valve or plug on the drain pipe 340), and it can also be used for draining water during the rainy season. When the water level in the pool body 310 is lower than the normal water level lower limit 360, the drain pipe 340 and the water circulation driving mechanism 40 can be closed so that the water level of the pool body 310 remains between the normal water level upper limit 350 and the normal water level lower limit 360. The rainwater coming out of the drain pipe 340 can be diverted to the existing tunnel drainage system to drain the excess rainwater in time.

[0040] As a preferred embodiment, it further includes a third water conveyance component 520 and a longitudinal drainage side ditch 530 arranged outside the tunnel. One end of the third water conveyance component 520 is communicated with the reservoir, and the other end of the third water conveyance component 520 is communicated with the longitudinal drainage side ditch 530. The third water conveyance component 520 can be a water pipe or an open channel. Further, a valve can be provided on the water pipe for easy control;

[0041] In order to further adapt to the rainy season conditions, this embodiment also sets a longitudinal drainage side ditch 530 outside the tunnel to increase the drainage capacity. Specifically, during the rainy season, the rainwater collected by the reservoir can also be diverted into the longitudinal drainage side ditch 530 through the third water conveyance component 520 to drain the excess rainwater in time.

[0042] As a preferred embodiment, the stepped waterfall structure 20 includes a first stepped waterfall structure 210 and a second stepped waterfall structure 220. The first stepped waterfall structure 210 is arranged above the return water pool 30, and the second stepped waterfall structure 220 is arranged above the longitudinal drainage side ditch 530. The return water pool 30 and the longitudinal drainage side ditch 530 are arranged staggeredly in the transverse direction of the tunnel. The water inlet end of the second stepped waterfall structure 220 is communicated with the third water delivery component 520 through a fourth water delivery component 540. The rainwater flowing out of the first stepped waterfall structure 210 enters the return water pool 30, and the rainwater flowing out of the second stepped waterfall structure 220 enters the longitudinal drainage side ditch 530.

[0043] Furthermore, the first stepped waterfall structure 210 and the return water pool 30 are arranged between the left tunnel line 610 and the right tunnel line 620, and the second stepped waterfall structure 220 and the longitudinal drainage side ditch 530 are arranged outside the left tunnel line 610 or the right tunnel line 620.

[0044] Specifically, the position where the stepped waterfall structure 20 is arranged can be set according to actual needs. In this embodiment, the first stepped waterfall structure 210 is arranged between the left tunnel line 610 and the right tunnel line 620, and the second stepped waterfall structure 220 is arranged outside the left tunnel line 610 or the right tunnel line 620. The first stepped waterfall structure 210 can be communicated with the first water delivery component through a water delivery pipe, and can also be communicated with the third water delivery component 520 through a water delivery pipe. In this way, in the dry season, part of the rainwater can be diverted to the second stepped waterfall structure 220 through the first water delivery component and the corresponding drainage pipe to form a stepped waterfall landscape. In the rainy season, part of the rainwater can be diverted to the second stepped waterfall structure 220 through the third water delivery component 520 and the corresponding drainage pipe to form a stepped waterfall landscape.

[0045] As a better example, the number of the second stepped waterfall structures 220 is less than the number of the first stepped waterfalls. In order to improve the landscape effect at the tunnel entrance, the stepped waterfalls are mainly arranged in the area between the left tunnel line 610 and the right tunnel line 620, and a small number of the stepped waterfall structures 20 are arranged outside the left tunnel line 610 or the right tunnel line 620.

[0046] Furthermore, the first water delivery component, the second water delivery component 510, the third water delivery component 520, and the fourth water delivery component 540 are all drainage pipes. Using drainage pipes can be laid underground or in hidden areas, and can be blocked by the outer false mountain body, without occupying the ground space.

[0047] Further, the diameter of the third water delivery component 520 is larger than that of the first water delivery component. It should be noted that the main purpose of the third water delivery component 520 is for flood discharge during the rainy season, and the main purpose of the first water delivery component is to supply water to the drop waterfall structure 20 during the dry season. In order to adapt to the change of rainwater flow during the rainy season, in this embodiment, the diameter of the third water delivery component 520 is larger than that of the first water delivery component.

[0048] Further, the water circulation driving mechanism 40 is a water pump. Preferably, a centrifugal pump can be used. By rotating the impeller, centrifugal force is generated on the water, so that the water is sucked from the low-pressure area and pushed to the high-pressure area, thereby realizing the water circulation on the rockery drop waterfall structure.

[0049] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
