l SLOPE PROTECTION BRICK FOR RESTORING VEGETATION BUFFER ZONE TECHNICAL FIELD

[01] The present invention relates to the technical eld of slope protection devices, and in particular to a slope protection brick for restoring a vegetation buffer zone. BACKGROUNDART

[02] River channel dredging refers to blow and stir silt deposited on a river bottom into turbid water by using a mechanical apparatus, such that the silt ows away with river water, thus playing the role of dredging a river channel. After river channel dredging is completed, vegetation is often planted to improve water conservation capacity and minimize soil erosion. At an initial stage of vegetation planting, the protection capacity is often poor. In this case, it is necessary to perform protection by using slope protection bricks to reduce silt entering the river channel and ensure the smooth growth ofthe vegetation.

[03] A slope protection brick for restoring avegetation bufferzone after river channel dredging is disclosed in the Chinese patent (Patent Publication No.: CN213173581U) and includes a main body, where an anti-skid block is xedly mounted at a top of the main body, limiting blocks are xedly mounted at a top of a rear end and a bottom of a front end of the main body, a water channel is provided at a periphery of the top ofthe main body, protective covers are xedly mounted at a left end and a right end of the periphery ofthe top ofthe main body, drain holes are provided in middles ofboth sides and a middle ofthe bottom ofthe main body, and awater discharge chamber is arranged in a middle of an interior of the main body. According to the slope protection brick for restoring a vegetation buffer zone after river channel dredging, the main body, xing strips, the limiting blocks, etc. are arranged to achieve the purpose of a good slope protection effect. The main body is of a Z-shaped structure, and a plurality of main bodies can be mutually overlapped andmounted in coordination with the limiting blocks in a longitudinal direction. Moreover, the main bodies are clamped on the xing strips in a transverse direction by means ofclamping grooves, and the slope protection bricks in the transverse direction and the longitudinal direction cooperate with each other for use, such that the integrity is good, and slope protection capability is strong.

[04] A slope protection brick for a mountain and a slope protection and drainage system for amountain composed ofsame are disclosed in another Chinese patent (Patent Publication No.: CNlll305239B), where the slope protection brick is of a hollow hexagonal brick body, and six side edges each are provided with an upper embedding opening and a lower embedding opening. One end of an L-shaped water seepage bafe is provided with a convex groove matching the upper embedding opening, and the other end of the L-shaped water seepage bafe is provided with a water seepage bafe. A convex groove matching the lower embedding opening is provided in one side surface ofawater retention straight plate, and all thewater retention straight plates areembedded and connected by means of regular triangular prism connecting plates. Two drainage connection manners including a primary drainage system and a secondary drainage system are arranged between the slope protection bricks, the primary drainage system is formed by embedding and splicing the L-shaped water seepage bafe, the water retention straight plate and the regular triangular prism connecting plate, and the secondary drainage system is formed by embedding and splicing the L-shaped water seepage bafe, the water retention straight plate, the regular triangular prism connecting plate and a rhombic drainage plate.

[05] Although the above slope protection brick for restoring avegetation buffer zone after river channel dredging can play a role ofslope protection, the slope protection brick needs to be mounted by means of an additional xing strip, which is troublesome to transport and mount, and specic parts need to be customized or machined according to different areas, which increases a construction cost. The slope protection brick in the slope protection brick for a mountain and a slope protection and drainage system for a mountain composed ofsame also needs to be spliced, since plates with different shapes and structures are required to be spliced, which greatly increases difculty and reduces efciency ofconstruction and also brings troubles to transportation. SUMMARY

[06] A slope protection brick for restoring a vegetation buffer zone provided by the present invention solves the problem that an existing slope protection brick has a high construction cost.

[07] In order to achieve the above objective, the technical solution employed by the present invention is as follows:

[08] A slope protection brick for restoring avegetation buffer zone includes a regular hexagonal brick main body, and an interior of the brick main body employs a hollow structure. Each side wall of the brick main body is provided with a water input hole, a top and abottom ofthe brick mainbody are provided with funnel-shaped drain hoppers, and a side wall of each drain hopper is made of a water permeable material. A sealing block is arranged in each drain hopper in an abutted manner, the sealing block and the brick main body are jointly provided with a plurality of inverted trapezoidal grooves which are in mutual communication, and a limiting block is clamped in each inverted trapezoidal groove. A sliding cylinder is arranged between the two drain hoppers in a communication manner, two sliding plates are slidably and hermetically connected in the sliding cylinder, and a spring is connected between the two sliding plates. Both ends ofthe sliding cylinder are in threaded connection to limiting rings positioned outside the corresponding sliding plates, and both sides of the sliding cylinder are symmetrically provided with drain ports.

[09] Preferably, a lter screen is connected between the side wall of the brick main body and the sliding cylinder, and one end ofthe lter screen is wrapped in an edge of the drain port.

[10] By means ofthe above arrangement, sludge collection can be realized by means ofthe lter screen, and sludge is prevented from owing into a river channel again.

[11] Preferably, the sliding cylinder is internally provided with a plurality of vent holes facing the lter screen.

[12] By means of the above arrangement, when the sliding plate is driven by rainwater and the sludge to move a center of the sliding cylinder, air in the sliding cylinder can beblown to the lter screen, such that partially blocked meshes ofthe lter screen can be blown through, and a use effect ofthe lter screen can be maintained.

[13] Preferably, a thickness of the sliding plate is the same as a height of the drain hopper.

[14] By means ofthe above arrangement, the water absorption and drainage rate can be adjusted according to rainfall in different regions and seasons, namely, and sludge collection and rainwater drainage can be realized only by removing one sealing block when the slope protection brick is in a normal state. When the water absorption and drainage amount needs to be increased, two sealing blocks on part or all of the slope protection bricks can be removed simultaneously when the slope protection bricks are laid, and a limiting ring can be removed simultaneously to keep the sliding plate positioned at the upper side to always open the drain port.

[15] Preferably, the side, facing the drain hopper, of the sliding plate employs a structure with a higher middle and a lower edge.

[16] By means ofthe above arrangement, the sludge is conveniently accumulated on both sides ofthe sliding plate, and the sludge can be quickly washed into the lter screen by virtue ofrainwater.

[17] Compared with the prior art, the present invention has the benecial effects as follows:

[18] According to the solution, sludge collection is realized by virtue of the lter screen, and an inner space ofthe brick main body is conductive to sludge precipitation, such that the possibility that the sludgeows back to the river channel is furtherreduced. Furthermore, collection of partial rainwater can be realized by utilizing the inner space of the brick main body, such that the weight of the slope protection brick is increased, and the stability is maintainedwhen a plurality of slope protection bricks are combined. The slope protection brick is mainly applied to areas where soil erosion is likely to be caused of rivers and lakes. After the slope protection brick is paved, the whole area is simple and beautiful.

DETAILED DESCRIPTIONOF THEEMBODIMENTS

[25] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[26] As shown in FIGs. 1-5, a slope protection brick for restoring a vegetation buffer zone includes a regular hexagonal brick main body 1, and an interior ofthe brick main body l employs a hollow structure. A center ofeach side wall ofthe brick main body l is provided with a water input hole 2, and mutual communication can be realized after a plurality of slope protection bricks are connected and mounted by means of the water input hole 2, such that rapid drainage is facilitated. Centers of a top and a bottom ofthe brickmainbody 1 are both provided with funnel-shaped drain hoppers 3, and a side wall of each drain hopper 3 is made of a water permeable material. In this example, porous concrete is employed for manufacturing the side wall ofthe drain hopper, such that rapid drainage of rainwater in the drain hopper 3 is facilitated, and sludge is remained in the drain hopper 3. A sealing block 4 is arranged with the shape matching the drain hopper 3 is arranged in each drain hopper 3 in an abutted manner, and the sealing block 4 and the brick main body 1 are jointly provided with six inverted trapezoidal grooves which are in mutual communication. The six inverted trapezoidal grooves are circumferentially and equidistantly distributed at a center of the corresponding side length on the top or the bottom, a limiting block 5 is clamped in each inverted trapezoidal groove, and connection limiting of two slope protection bricks can be realized by means of the limiting blocks 5.

[27] A sliding cylinder 6 located in the brick main body 1 is arranged between the two drain hoppers 3 in a communication manner, and two sliding plates 7 are slidably and hermetically connected in the sliding cylinder 6. A thickness ofeach sliding plate 7 is the same as a height ofthe drain hopper 3, and the side, facing the drain hopper 3, of each sliding plate 7 employs a structure with a higher middle and a lower edge, such that the sludge can easily slide to both sides of the sliding plate 7 under the impact of the rainwater, which is conductive to improvement ofthe efciency of sludge collection. A spring 8 is connected between the two sliding plates 7, and both ends of the sliding cylinder 6 are in threaded connection to limiting rings 9 positioned outside the corresponding sliding plates 7, such that the sliding plates 7 can be prevented from sliding out of the sliding cylinder 6 by virtue of the limiting rings 9. A front side and a rear side of an upper end and a lower end of the sliding cylinder 6 are symmetrically provided with drain ports 10, and bottoms of the drain ports 10 are ush with bottoms ofthe sliding plates 7. A lter screen 11 is connected between the side wall ofthe brick main body 1 and the drain port 10, the lter screen 11 is arc-shaped, and the lter screen ll completely covers an edge ofthe drain port 10, such that the sludge completely falls onto the lter screen ll under the impact of the rainwater. A middle of the sliding cylinder 6 is provided with vent holes 12, the three vent holes 12 are distributed on the sliding cylinder 6 at intervals, and the three vent holes 12 are all located within a transverse width range of the lter screen ll. Each vent hole 12 is Y-shaped, and two air output ends of the vent hole 12 are oriented towards the corresponding lter screen 1 1.

[28] The working process of this solution is as follows:

[29] When a single slope protection brick is not mounted, the spring 8 is compressed to enable the two sliding plates 7 to abut against the corresponding limiting rings 9, and the sealing block 4 is xed in the drain hopper 3 under the action of the limiting block 5. When the slope protection brick is laid, other auxiliary xing parts are not needed, such that the slope protection brick is convenient to load and transport, and the related transportation cost is reduced. Moreover, a front side and a back side do not need to be distinguished during mounting, only any limiting block 5 on one sidewheretwo adjacent slope protection bricks abut against each other needs to be removed, and the other limiting block 5 is clamped in the inverted trapezoidal groove in communication with thetwo slope protection bricks, such that connection limiting ofthetwo slope protection bricks can be realized, operation is simple, convenient and fast, the mounting difculty is reduced, and the construction efciency can be improved. After mounting is completed, the whole slope protection brick looks simple and beautiful.

[30] When a plurality of slope protection bricks are connected and limited, the sealing blocks 4 on the upper sides of all the slope protection bricks are removed, sludge enters the drain hoppers 3 through the surfaces of the slope protection bricks under washing of rainwater, and nally, the sludge is gradually accumulated on both sides of the sliding plates 7, and the sludge and the rainwater can be efciently collected and separated by means of the funnel-shaped drain hopper 3. Furthermore, since the side wall ofthe drain hopper 3 is made ofporous concrete, the rainwater passing through the side wall of the drain hopper 3 can be quickly leaked into the interior of the slope protection brick, and rainwater collection is realized by virtue of the inner space of the slope protection brick. When being higher than the water input holes 2 in the middle of the slope protection brick, the rainwater can be quickly led to the interiors of other slope protection bricks by means ofthe plurality ofwater input holes 2, and nally discharged through the water input holes 2 ofthe slope protection brick positioned at the outer side.

[31] When the weight ofthe sludge on the sliding plate 7 is gradually increased, the sliding plate 7 can be continuously pressed down, and nally the sludge on the sliding plate 7 is pushed into the lter screen 1 1 from the drain port 10 by virtue ofthe rainwater, and collection of the sludge can be realized by means of the lter screen 11, and the rainwater passes through the lter screen 11. During downward pressing of the sliding plate 7, the sliding plate 7 can push airbetween thetwo sliding plates 7 tobeblown from the vent holes 12 to the two lter screens 11, thereby helping to blow through the partially blocked meshes ofthe lter screens 11. When the impact force ofthe rainwater is greater than the elastic force of the spring 8 on the sliding plate 7, the sliding plate 7 can also be pushed to slide downwards, such that a water absorption effect is further increased by means ofthe drain port 10.

[32] Afterthe sludge enters the lter screen 11 viathe drain port 10, part ofthe sludge with a smaller particle size may still enter the slope protection brick by means of ltration, and in this case, and the inner space of the slope protection brick can play a role ofbuffer precipitation forthe sludge with a smaller particle size, such thatthe sludge is precipitated and collected at a bottom ofthe interior ofthe slope protection brick, and the situation that the sludge enters the river channel is further avoided.

[33] In a mounting process ofthe slope protection brick, the drainage efciency after mounting ofthe plurality ofslope protection bricks can also be adjusted according to the rainfall in different regions and different seasons, and only when the plurality of slope protection bricks are mounted, the limiting rings 9 and the sealing blocks 4 on the lower sides of part of the slope protection bricks and the sealing blocks 4 on the upper sides are removed at the same time, such that the sliding plates 7 in the slope protection brick with thetwo sealing blocks 4 removed moves down, and the drain ports 10 in the sliding cylinder 6 are completely opened. In this case, certain gaps exist between the side walls of the drain hoppers 3 positioned at the lower sides and the sliding plates 7, such that when a large amount ofrainwater enters the slope protection brickby means ofthe side walls of the drain hoppers 3 positioned at the upper sides and the drain ports 10, the rainwater can quickly ow out by means of the slope protection brick positioned at the lower side, and the drainage efciency is accelerated. Moreover, when a water level in the slope protection brick is lower than that ofthe water input holes 2, the six adjacent slope protection bricks can be assisted in drainage, such that the drainage capacity can be adjusted according to actual needs after the slope protection bricks are mounted, the application range of the solution is further broadened, and a good protection effect is played on the restoration ofthe vegetation buffer zone.

It shall be noted that those ofordinary skill in the artmay also make several transformations and improvements on the premise of not deviating from the structure ofthe present invention, and these transformations and improvements shall fall within the protection scope of the present invention, and will not affect the implementation effects ofthe present invention and the practicability ofthe patent. The protection scope claimedby this application shall be subject to the contents ofthe claims, and the particular embodiments and other descriptions in the description may be used for interpreting the contents ofthe claims. -9-
