Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hydraulic engineering, and particularly relates to a slope protection device for hydraulic engineering construction and a construction method thereof. BACKGROUND

[0002] At present, corresponding protection projects are built on the slopes of highways, railways, reservoirs and river channels to prevent collapse and erosion of the slopes of related projects, thereby protecting the normal use of the main projects. The current slope protection of related projects often adopts the forms of stone masonry slope, cast-in-situ concrete slope and concrete precast block masonry slope. In the slope protection project of water conservancy construction, the slope protection device needs to be planted with slope vegetation due to the need to consider the factors of hydrological ecological environment, so as to reduce the runoff returning to the lake and sea through the transpiration of the vegetation, thereby enabling the area radiated by the river to be able to carry out small-scale water circulation, thereby changing the climate and reducing soil erosion. Therefore, the slope protection device used in water conservancy projects is usually a concrete block slope protection brick.

[0003] The existing slope protection brick has many defects in actual use.

[0019] Beneficial effects

[0020] Compared with the prior art, the beneficial effects of the present application are:

[0021] (1) In the present application, the planting grid is laid in the hole for planting slope vegetation on the traditional slope protection brick, which can ensure that the grass seeds of the slope vegetation are scattered into the planting hole of the slope protection brick, and prevent the rainwater from directly washing the planting hole before the slope vegetation germinates, causing soil erosion in the planting hole, resulting in cavities under the slope protection brick, causing the displacement of the slope protection brick and further causing the collapse of the entire slope surface, the planting grid is uniformly provided with through holes with the same aperture size, which can ensure the entry of grass seeds and rainwater, prevent rainwater from directly washing the river slope, and also allow the grass seeds to grow out of the through holes of the planting grid after germination, ensuring the normal growth of the slope vegetation and preventing rainwater from washing the slope surface, and the planting grid can also avoid direct sunlight during the growth of the grass seeds, because in practical use, the river slope is usually not frequently irrigated, which often causes water shortage in the upper half of the river slope, and the germination effect of the grass seeds is not good under the condition of water shortage, and direct sunlight will cause the seedlings to wither, and the planting grid can avoid direct sunlight to reduce evaporation of the planting hole of the slope protection brick, ensuring the normal germination and growth of the grass seeds, and the hole can also scatter light to ensure the normal sunlight required for the growth of the grass seeds.

[0022] (2) In the present application, in order to further ensure that the planting grid can play a role in buffering rainwater and preventing rainwater from directly washing the slope surface, a baffle is further arranged on the lower surface of the planting grid, the baffle is arranged obliquely, so that the grid holes of the planting grid are blocked by the baffle in the vertical direction, so that when the rainwater passes through the grid holes of the planting grid, it is further blocked by the baffle, preventing the rainwater from directly impacting the slope surface, and according to the phototaxis of plants, when the grass seeds in the planting hole of the slope protection brick germinate, they will grow out of the grid holes of the planting grid by bypassing the baffle, so that the baffle can block the rainwater from washing the slope surface and will not hinder the growth of the vegetation, when the rainwater is too large, the water content of the soil on the river slope is saturated, which will cause the saturated mud and water to be washed down with the rainwater, and the obliquely arranged baffle can block the turbid rainwater from overflowing out of the bottom of the slope protection brick, causing soil erosion, and the specific reason is that without the blocking of the baffle, the rainwater that continues to fall after the water absorption and preservation of the river slope will form a turbid mud water state with the soil, overflow from the planting hole of the slope protection brick and then flow into the river from the slope, causing the sediment in the river to deposit and raise the river surface, but the sediment in the mud water is relatively heavy, so it will gradually sink when the water flow is slow and will not be carried into the river with the water flow, the arrangement of the baffle can block the sinking speed of the mud water, so that the sediment in the mud water can be settled, and finally the amount of sediment in the water flowing into the river can be greatly reduced, preventing soil erosion and slowing down the sediment deposition of the river.

[0023] (3) In the application, considering that the traditional slope protection bricks are only fixed on the river channel by paving, and the slope protection bricks are not connected, which can cause the whole slope surface to not form a whole, when one of the slope protection bricks subsides, the soil around the subsided slope protection brick is exposed, which causes water and soil loss after raining, and further causes a chain reaction, therefore, in the application, the slope protection bricks are connected by the connecting mechanism arranged on the slope protection bricks, so that the slope protection bricks form a whole after paving, which is better for the protection of the river slope surface, and can prevent the subsidence of individual slope protection bricks due to the loose soil in the paving area, the abutting block is arranged on one side surface of the slope protection brick, the abutting hole is arranged on the other side surface, so that the horizontally arranged slope protection bricks on the river slope are directly connected to form a whole, and the abutting strip and the abutting groove are arranged on the upper and lower end surfaces of the slope protection brick, so that the vertically arranged slope protection bricks on the river slope form a whole.

[0024] (4) In the application, in order to ensure that the slope protection bricks can be closely connected with the river slope surface during paving, and not deviate from the position to expose the river slope surface due to the pressure of people, and cause water and soil loss due to the rainwater flowing into the gap, the embedded tooth for grabbing the ground is arranged on the slope protection brick, the slope protection brick is fixed by inserting the embedded tooth into the slope surface, the embedded tooth is provided with the fin, and the fin is upwardly opened, so that the embedded tooth can be smoothly inserted into the river slope surface during paving, and the fin is used for increasing the friction when the embedded tooth is pulled out, so that the slope protection brick is difficult to be lifted from the surface after paving, and the insertion hole is arranged at the four corners of the slope protection brick, and the iron peg is inserted into the hole, so that the slope protection brick is fixed and installed in advance, and the position of the slope protection brick is further stabilized.

DETAILED DESCRIPTION

[0034] The application will be further described below in combination with the specific embodiments.

[0035] In the Figure 1 The slope protection device for hydraulic engineering construction provided in the application comprises slope protection bricks 2 for protecting the slope surface of a river channel, the slope protection bricks 2 are uniformly provided with multiple cross beams 8 for strengthening the strength of the slope protection bricks 2 along the width direction, and the slope protection bricks 2 are uniformly provided with multiple longitudinal beams 9 also for strengthening the strength of the slope protection bricks 2 along the length direction, the cross beams 8 and the longitudinal beams 9 are cross-connected to form multiple planting holes 13 for sowing slope vegetation, and the planting holes 13 are paved with planting grids 3 for preventing water and soil loss and providing shelter for grass seed germination, the bottom of the planting grids 3 is fixedly connected with multiple baffles 14 for preventing rainwater from directly washing the planting holes 13, and the baffles 14 can also play a role in moisture retention and sun shading, the baffles 14 and the upper surface of the planting grids 3 are in an inclined state, which can prevent sunlight from directly irradiating the germinating slope plants through the planting grids 3, the upper surface of the slope protection bricks 2 is provided with insertion holes 7 for connecting displacement components for limiting the slope protection bricks 2, and iron stakes 1 for fixing the slope protection bricks 2 on the river channel are inserted into the insertion holes 7, the length of the iron stakes 1 is longer than the thickness of the slope protection bricks 2, so that the length required for fixing the slope protection bricks 2 can be met, the slope protection bricks 2 are laid on the river channel, the iron stakes 1 are inserted into the insertion holes 7 on the upper surface of the slope protection bricks 2, the iron stakes 1 pass through the insertion holes 7 and extend into the slope surface of the river channel, so that the slope protection bricks 2 are fixed, preventing the slope protection bricks 2 and the underlying river channel soil surface from not being closely attached, causing water loss through the gap between the slope protection bricks 2 and the river surface in the rainy season, and the planting grids 3 paved in the planting holes 13 formed by the cross connection of the cross beams 8 and the longitudinal beams 9 on the slope protection bricks 2 can not only prevent rainwater from directly washing the planting holes 13, causing water and soil loss in the planting holes 13, but also provide shade for the slope vegetation germinating in the planting holes 13, so that the vegetation can be sheltered when it is not fully grown and avoid direct sunlight causing dryness.

[0036] InFigure 3 And 4 In the planting grid 3, the through holes for rainwater and plant growth are evenly arranged, and the through holes are located between two adjacent baffles 14. When the revetment brick 2 is cut open and viewed vertically downward from the cross section, it can be seen that the grid holes of the planting grid 3 are blocked by the baffles 14. In this way, the rainwater is first blocked by the planting grid 3 during the falling process, preventing the rainwater from directly falling into the planting hole 13 and causing soil erosion. When part of the rainwater passes through the grid holes of the planting grid 3, it is further blocked by the baffles 14, preventing the rainwater from directly impacting the slope surface. According to the phototropism of plants, when the grass seeds in the planting hole 13 of the revetment brick 2 germinate, they will grow out of the grid holes of the planting grid 3 by bypassing the baffles 14, so that the baffles 14 can block rainwater from eroding the slope surface and will not hinder the growth of vegetation.

[0037] In Figure 3 And 4 The inclined baffles 14 arranged transversely on the lower surface of the planting grid 3 can also block turbid rainwater from overflowing out of the bottom of the revetment brick 2, preventing soil erosion. The specific reason is that without the obstruction of the baffles 14, the soil on the river slope surface will form turbid mud water after absorbing water and retaining, overflowing from the planting hole 13 of the revetment brick 2, and then the mud water will flow from the slope surface into the river, causing the sediment in the river to deposit and raise the river surface. However, the sediment in the mud water is relatively heavy in volume, so it will gradually sink when the water flow is slow, and will not be carried into the river with the water flow. Therefore, when the planting grid 3 is buckled in the planting hole 13, the end of the baffle 14 is inserted into the soil on the slope surface in the planting hole 13. When the rain comes, the baffle 14 can block the flow speed of the mud water, so that the sediment in the mud water can settle, and finally the amount of sediment in the rainwater that seeps into the river can be greatly reduced, preventing soil erosion and slowing down the sediment deposition in the river.

[0038] In Figure 5In the embodiment, another arrangement of the baffle 14 is provided, in which the baffle 14 arranged obliquely is arranged longitudinally equidistantly along the lower surface of the planting grid 3, so that two planting grids 3 with different arrangements of the baffle 14 on the lower surface are obtained. The longitudinal baffle 14 is arranged for the purpose that, if all the planting grids 3 have the baffle 14 arranged transversely on the bottom, when the baffle 14 is inserted into the river slope, the rainwater will flow downward from the gap between two adjacent groups of the transversely arranged baffle 14, so that the flow rate of the rainwater is faster and faster, and the flow of the rainwater is larger and larger, so that the river slope soil on the lower surface of the longitudinal beam 9 of the slope protection brick 2 is eroded by the rainwater, and a cavity is formed. At this time, the rainwater flowing down from the transversely arranged baffle 14 needs to be guided, so the longitudinal baffle 14 is arranged to guide the rainwater flowing downward to the next layer of the transversely arranged baffle 14 to slow down. When the planting grid 3 is installed, the two planting grids 3 with different arrangements of the baffle 14 are installed adjacent to each other in a staggered manner, so that the baffle 14 arranged longitudinally and transversely forms a barrier on the river slope. After the rainwater is blocked by the transversely arranged baffle 14, the flow rate of the rainwater is slowed down. At this time, the rainwater will continue to flow downward through the two ends of the transversely arranged baffle 14, and the rainwater flowing downward will be guided by the longitudinally arranged baffle 14 to flow to the next layer of the transversely arranged baffle 14 to slow down, so that the rainwater is slowed down, and the river slope is prevented from being eroded by the flowing rainwater.

[0039] In Figure 2 In the embodiment, at least one tenon 10 for bearing the planting grid 3 is arranged at each corner of the inner wall of the planting hole 13, and the length of the tenon 10 is not less than the thickness of the edge of the through hole on the planting grid 3. The front end of the upper surface of the tenon 10 is arranged in a hook structure. Since the riverbed is a slope structure, the slope protection brick 2 can only be arranged obliquely. If the planting grid 3 is directly placed on the tenon 10, the planting grid 3 will be easily separated from the slope protection brick 2 under the impact of the rainwater, so that the planting grid 3 loses its function, and may also fall into the river to cause pollution or blockage. Therefore, the planting grid 3 must be buckled on the tenon 10, so the length of the tenon 10 needs to exceed the edge of the planting grid 3, that is, the tenon 10 needs to exceed the thickness of the mesh of the planting grid 3 to be inserted into the mesh to further clamp the planting grid 3. The hook structure on the upper surface of the tenon 10 is convenient for being inserted into the mesh of the planting grid 10 and then being hung and fixed.

[0040] In Figure 6 and 7In the present application, the slope protection brick 2 is a high-strength concrete block structure. The concrete block structure can make the service life of the slope protection brick 2 longer, and can resist the impact force caused by carrying and dumping during transportation. The slope protection brick 2 is provided with a frame 16 formed by binding with steel bars at the upper and lower ends. Two frames 16 are connected by a connecting bar 15 to form a whole. The frame 16 includes a stirrup 18 supporting the overall structure of the slope protection brick 2. A plurality of longitudinal tensioning bars 19 are arranged on the stirrup 18 along the length direction to resist the tensile force of the slope protection brick 2 from the length direction. A plurality of transverse tensioning bars 17 are arranged on the stirrup 18 along the width direction to resist the tensile force of the slope protection brick 2 from the width direction. The transverse tensioning bars 17 and the longitudinal tensioning bars 19 are connected alternately to form a steel bar network, so that the overall strength of the slope protection brick 2 is enhanced and it is not easy to break during transportation and laying. Considering that the environment used by the slope protection brick 2 is relatively harsh, and it is also easy to be subjected to violence during transportation and laying, and the slope protection brick 2 needs to resist wind and rain erosion and root erosion of slope vegetation for a long time, the slope protection brick 2 must have a certain strength. Concrete is a relatively ideal material that can meet the strength requirements of the slope protection brick 2. In order to ensure that the slope protection brick 2 will not be broken due to impact during loading and unloading, the frame 16 made of steel bars is added to the concrete. Since the slope protection brick 2 has a certain thickness, two frames 16 are arranged at the upper and lower ends of the slope protection brick 2 respectively, and are connected by the connecting bar 18 to form a whole.

[0041] In Figure 1 、 2In the traditional way, the slope protection bricks 2 are fixed on the river channel by paving, and the slope protection bricks 2 are not connected, which causes the whole slope surface to not form a whole, and when one of the slope protection bricks 2 sinks, the soil around the sinking slope protection brick 2 is exposed, which causes water and soil loss after raining, and further causes a chain reaction. Therefore, in the present application, one side of the outer surface of the slope protection brick 2 is integrally connected with an abutting block 5 for connecting the adjacent slope protection bricks 2, and the other side of the outer surface of the slope protection brick 2 is provided with an abutting hole 12 for accommodating the abutting block 5 on the adjacent slope protection brick 2, one end of the outer surface of the slope protection brick 2 is integrally connected with an abutting strip 4 for connecting the slope protection brick 2 adjacent to the upper end, and the other end of the outer surface of the slope protection brick 2 is provided with an abutting groove 11 for connecting the abutting strip 4 on the slope protection brick 2 adjacent to the lower end, the edge of the lower surface of the slope protection brick 2 is provided with an embedded tooth 6 for gripping the ground, and the embedded tooth 6 is a four-sided tapered structure to increase the contact surface with the ground, the upper surface of the embedded tooth 6 is integrally connected with a threaded sleeve 20 for connecting the lower surface of the slope protection brick 2, and the edge of the lower surface of the slope protection brick 2 is correspondingly provided with an internal thread pipe for accommodating the threaded sleeve 20 on the upper surface of the embedded tooth 6, and the opposite sides of the embedded tooth 6 are provided with fins 21. In order to ensure that the slope protection brick 2 can be closely connected with the river slope during paving, and not to be deviated from the river slope due to the pressure of people on it, and not to cause water and soil loss in the gap in the later rainwater irrigation, the embedded tooth 6 is arranged on the slope protection brick 2 to fix the slope protection brick 2 by inserting into the slope, and the fins 21 on the embedded tooth 6 are upwardly opened, so that the embedded tooth 6 can be smoothly inserted into the river slope during paving, and the fins 21 can increase the friction when pulling out, so that the slope protection brick 2 is difficult to be lifted from the river slope after paving.

[0042] A slope protection method for water conservancy construction, which is constructed by using a slope protection device, and the steps are as follows:

[0043] In step one, the embedded tooth 6 is assembled on the lower surface of the slope protection brick 2 by the threaded sleeve 20, a plurality of slope protection bricks 2 are sequentially connected and fixed on the river channel by the abutting hole 12, the abutting block 5, the abutting strip 4 and the abutting groove 11, the embedded tooth 6 is inserted into the soil of the river slope to fix the slope protection brick 2, and the fins 21 on the embedded tooth 6 increase the friction to make the slope protection brick 2 difficult to be lifted from the river slope after paving;

[0044] In step two, the iron rod 1 is inserted into the soil of the river slope through the insertion hole 7 to fix the slope protection brick 2, so as to prevent the slope protection brick 2 and the lower river soil surface from not being closely combined, and to prevent the water from flowing through the gap between the slope protection brick 2 and the river surface to cause water and soil loss in the rainy season;

[0045] Step three, the planting hole 13 of the slope protection brick 2 is laid with a planting grid 3, which can prevent rainwater from directly washing the planting hole 13 and causing soil erosion in the planting hole 13, and can also provide shade for the slope protection vegetation growing in the planting hole 13. The planting grid 3 is provided with a baffle 14, which is inclined, so that the grid holes of the planting grid 3 are blocked by the baffle 14 in the vertical direction. In this way, when the rainwater passes through the grid holes of the planting grid 3, it will be further blocked by the baffle 14 to prevent the rainwater from directly impacting the slope surface. At the same time, according to the phototropism of plants, when the grass seeds in the planting hole of the slope protection brick 2 germinate, they will grow out of the grid holes of the planting grid 3 by bypassing the baffle 14, so that the baffle 14 can block rainwater from washing the slope surface without hindering the growth of vegetation. The inclined baffle 14 can also block turbid rainwater from overflowing out of the bottom of the slope protection brick 2, causing soil erosion;

[0046] Step four, the baffle 14 has another arrangement, the inclined baffles 14 are arranged longitudinally and equidistantly along the lower surface of the planting grid 3. When the planting grid 3 is installed, two planting grids 3 with different arrangement directions of the baffles 14 are installed adjacent to each other in a staggered manner, so that the longitudinal and transverse baffles 14 form a barrier on the slope surface of the river channel. Rainwater is slowed down after being blocked by the transversely arranged baffles 14. At this time, the rainwater will continue to flow downward through the two ends of the transverse baffles 14, and the downward flowing rainwater will flow to the next layer of transverse baffles 14 under the guidance of the longitudinal baffles 14, and finally achieve slow flow of rainwater, preventing the flowing rainwater from gathering into a stream to wash the slope surface of the river channel.

[0047] The above is a further detailed description of the present application in combination with the specific embodiments, which cannot be considered as limiting the specific embodiments of the present application to these descriptions. For ordinary skilled persons in the technical field to which the present application belongs, without departing from the concept of the present application, a number of simple deductions or substitutions can be made, which should be considered as belonging to the protection scope determined by the claims of the present application.
