Description

Technical Field

[0001] The utility model relates to a bank protection technology for embankment projects in the field of water conservancy projects, and is mainly used for embankment protection, flood control and drainage, and ecological management of urban rivers. Specifically, it relates to an ecological, standardized, assembled concrete bank protection structure. Background Art

[0002] Currently, the traditional method for managing urban rivers is to use gabion stone cages for revetment. This not only requires the mining, transportation, and consumption of large quantities of stone, but also causes permanent damage to the surrounding mountain ecosystems. Furthermore, the construction and application of gabion stone cage revetments in small and medium-sized rivers squeezes the living environment of aquatic plants and animals within the river, disrupts the exchange of materials and energy between the water system and the land, and blocks the healthy circulation of the water system. This often leads to a pungent odor in the river during the dry season. Utility Model Content

[0003] In order to solve the problem of large-scale resource consumption, ecological environment damage and biodiversity imbalance caused by traditional urban river management, the utility model provides an ecological standardized assembled concrete bank protection structure, which has the characteristics of lightweight, assembly, planting, resource conservation, easy construction, short construction period and good social and economic benefits.

[0004] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0005] An ecological standardized assembled concrete revetment structure, composed of standardized hollow concrete bricks and pine wood piles, characterized in that the standardized hollow concrete bricks include end standardized hollow concrete bricks, corner standardized hollow concrete bricks and universal standardized hollow concrete bricks;

[0006] Corner-shaped hollow concrete bricks are set at the front corners of the concrete revetment; end-shaped hollow concrete bricks are set at the front and sides of the concrete revetment;

[0007] The front side refers to the water-facing side in the length direction of the river channel; the side side refers to the water-facing side in the width direction of the river channel;

[0008] The remaining locations are all filled with general standardized concrete hollow bricks.

[0009] The standardized hollow concrete bricks are square, uncapped hollow concrete bricks with four circular openings at the bottom. The standardized hollow concrete bricks are laid closely according to the length and width of the proposed revetment. After the first layer of the bottom is laid, pine piles are driven vertically at equal intervals on the four sides and inside according to the position of the circular openings at the bottom of the standardized hollow concrete bricks. On the basis of treating the soft soil foundation, the bottom layer of hollow concrete bricks is fixed and constrained to prevent overall displacement. The concrete revetment structure adopts the mortise and tenon connection of the stacked assembly of standardized hollow concrete bricks. After each layer of standardized hollow concrete bricks is assembled, it is filled with sand until it is stacked and assembled to the designed height of the river bank. The concrete revetment structure after assembly is stepped, and each step is designed to be wave-proof and erosion-resistant. Aquatic grass seeds can be sown on the steps and top surface to achieve a green and ecological revetment.

[0010] The shaped hollow concrete bricks are arranged closely according to the length and width of the proposed revetment, that is, the shaped hollow concrete bricks used in the first layer at the bottom are arranged in X numbers in the horizontal direction and Y numbers in the vertical direction, with a total of X*Y numbers; the shaped hollow concrete bricks used in the second layer are arranged in X-1 numbers in the horizontal direction and Y-1 numbers in the vertical direction, with a total of (X-1)*(Y-1) numbers; the shaped hollow concrete bricks used in the third layer are arranged in X-2 numbers in the horizontal direction and Y-1 numbers in the vertical direction, with a total of (X-2)*(Y-1) numbers; the shaped hollow concrete bricks used in the fourth layer are arranged in X-3 numbers in the horizontal direction and Y- 2, for a total of (X-3)*(Y-2); the fifth floor uses standardized hollow concrete bricks with X-4 arranged horizontally and Y-2 arranged vertically, for a total of (X-4)*(Y-2); the sixth floor uses standardized hollow concrete bricks with X-5 arranged horizontally and Y-3 arranged vertically, for a total of (X-5)*(Y-3); the seventh floor uses standardized hollow concrete bricks with X-6 arranged horizontally and Y-3 arranged vertically, for a total of (X-6)*(Y-3); and so on. The Nth floor uses standardized hollow concrete bricks with X-(N-1) arranged horizontally. When N is an even number, there are Y-(N / 2) pieces arranged vertically, for a total of [X-(N-1)]*[Y-(N / 2)]. When N is an odd number, there are Y-[(N-1) / 2] pieces arranged vertically, for a total of [X-(N-1)]*{Y-[(N-1) / 2]} pieces. N is a natural number.

[0011] The wave- and erosion-resistant design incorporates a zigzag pattern on the front and side (either left or right) of the end and corner profiled hollow concrete bricks. This pattern, composed of multiple long, V-shaped hollow strips, forms a wave pattern on the water-facing surface of the bricks. This prevents erosion from river currents and effectively reduces wave impact, extending the bricks' service life.

[0012] There are three types of shaped concrete hollow bricks, which are divided into end shaped concrete hollow bricks, corner shaped concrete hollow bricks and universal shaped concrete hollow bricks.

[0013] The end-shaped concrete hollow brick is a pentahedral hollow concrete structure surrounded by the front, back, left, right and bottom surfaces, with a cross-shaped supporting stiffening rib in the middle. The cross-shaped supporting stiffening rib is provided with a cross-shaped groove corresponding to the bottom position. The cross-shaped groove divides the bottom surface evenly into four areas. Four circular holes are left in the center of each area of ​​the bottom surface to prevent the concrete hollow brick from floating up when encountering water; the front is a protruding wave-breaking plate, and the front of the wave-breaking plate is provided with a broken line hollow pattern.

[0014] The corner-shaped concrete hollow brick is a pentahedral hollow concrete structure surrounded by the front, back, left, right and bottom surfaces, with a cross-shaped supporting stiffening rib in the middle. A cross-shaped groove is left at the bottom position corresponding to the cross-shaped supporting stiffening rib. The cross-shaped groove divides the bottom surface evenly into four areas. Four circular holes are left in the center of each area of ​​the bottom surface to prevent the concrete hollow brick from floating up when it encounters water; the front and left (right) sides are protruding wave-breaking plates, and the front of the wave-breaking plates is provided with a broken line hollow pattern.

[0015] The universal standardized concrete hollow brick is a pentahedral hollow concrete structure surrounded by the front, back, left, right and bottom surfaces, with a cross-shaped supporting stiffening rib in the middle. The cross-shaped supporting stiffening rib has a cross-shaped groove corresponding to the bottom position. The cross-shaped groove divides the bottom surface evenly into four areas. Four circular holes are left in the center of each area of ​​the bottom surface to prevent the concrete hollow brick from floating up when it encounters water; the front, back, left and right sides are all the same height.

[0016] The pine piles are pointed cylindrical piles made of antiseptic-treated pine wood with a diameter of no more than 150 mm. The length of the pine piles is determined according to the actual geological conditions of the river channel.

[0017] The method of using the utility model is as follows: after dredging the urban river channel, the site of the proposed revetment is leveled, and after leveling, the shaped concrete hollow bricks are stacked and assembled according to the actual geological conditions of the river channel and the length and width of the proposed revetment; the end shaped concrete hollow bricks and the corner shaped concrete hollow bricks are closely arranged and laid on the outer edge and corner of the revetment, and the universal shaped concrete hollow bricks are closely arranged and laid inside the revetment; after the first layer of the bottom is laid, pine piles are evenly spaced on the four sides and inside of the revetment structure, and the pine piles are evenly spaced. The piles are driven vertically through the circular hole at the bottom of the concrete hollow bricks and then into the riverbed soil (the diameter of the pine piles is 100-150mm smaller than the circular hole at the bottom of the concrete hollow bricks). The height of the pine piles driven into the riverbed soil exceeds the height of the top surface of the shaped concrete hollow bricks by 100-200mm. After the pine pile construction is completed, the goal of reinforcing the soft soil foundation of the planned riverbank protection can be achieved, and the problem of fixed constraints in the riverbed after the stacking, assembly and laying of the shaped concrete hollow bricks can be solved, which can effectively prevent the overall displacement of the bank protection structure after it is floated in water. After the first layer of shaped concrete hollow bricks at the bottom is laid and the pine piles are driven, the excess sand and soil generated during the earthwork operation in the river channel is evenly filled into the concrete hollow bricks. The height of the sand filling is consistent with the height of the "cross" supporting stiffening ribs in the middle of the hollow bricks, so as to realize the use of local materials to increase the weight of the shaped concrete hollow bricks themselves and the later ecological planting; the second layer of shaped concrete hollow bricks uses the design of a cross-shaped groove on the bottom surface, and is stacked and inserted into the first layer of shaped concrete hollow bricks through the design of its own mortise and tenon structure to form a " The goal of interlocking and interconnecting the brick structures is achieved in the "cross" brick joints, and the standardized concrete hollow bricks can be assembled and connected in plane, outward expansion, inward contraction and corner interlocking. The above operations are repeated until the stacking and assembly reaches the designed height of the river bank protection. The top layer of concrete hollow bricks are all assembled with universal standardized concrete hollow bricks with flat top surfaces. After the assembly, the front, left and right sides of the concrete bank protection structure are stepped. Each step is designed to prevent waves and erosion. The steps and top surfaces can be sown with aquatic grass seeds to achieve a green and ecological bank protection.

[0018] The shaped hollow concrete bricks involved in the utility model can be standardized and industrially produced using prefabricated molds, and their own mortise and tenon structure design is fully utilized to realize the stacking and assembly of hollow concrete bricks and the interlocking and interconnection of brick structures. It has the advantages of simple processing and manufacturing, convenient installation and use, stable and reliable structure, low construction cost, and green ecological environment protection. It can be promoted and applied to urban small and medium-sized river embankment protection, flood control and drainage, and ecological management. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, an ecological standardized assembled concrete bank protection structure is characterized by being composed of pine piles 1, end standardized concrete hollow bricks 2, corner standardized concrete hollow bricks 3, and universal standardized concrete hollow bricks 4.

[0043] From bottom to top, the first layer of bricks is laid according to the length and width of the proposed revetment. End-shaped hollow concrete bricks 2 are laid closely together in front, on the left, and on the right sides of the proposed revetment. Corner-shaped hollow concrete bricks 3 are laid at the front, left, or right corners, and general-purpose hollow concrete bricks 4 are laid at the back. The wave-breaking plates 8 within the end-shaped hollow concrete bricks 2 and corner-shaped hollow concrete bricks 3 are located on the water-facing side of the river channel. The entire interior of the revetment is paved with general-purpose hollow concrete bricks 4. The end-shaped hollow concrete bricks 2, corner-shaped hollow concrete bricks 3, and general-purpose hollow concrete bricks 4 are closely aligned and arranged horizontally and vertically, forming a square shape upon completion.

[0044] The brick arrangement for the second layer is the same as for the first. In terms of length and width, compared to the planar dimensions of the first layer, only one row / column is reduced in the middle of each of the long and short sides. The front, left, right, and back sides are each offset by 1 / 2 the distance of a shaped hollow concrete brick, aligning them centrally with the bricks of the first layer. During installation, a cross-shaped groove 5 is provided on the bottom surface of the shaped hollow concrete brick. This groove is inserted into the cross-shaped joint 10 formed by the closely arranged bricks of the first layer. This creates a mortise and tenon joint structure, creating a mortise and tenon connection between the bricks.

[0045] The brick arrangement for the third layer is the same as for the first. In terms of length and width, compared to the second layer's planar dimensions, only one row is reduced in the middle along the short side. The front, left, and right sides are offset by half the distance of a shaped hollow concrete brick, and the back is flush with the back of the bricks in the first layer. During installation, a cross-shaped groove 5 is left on the bottom surface of the shaped hollow concrete bricks. This groove is inserted into the cross-shaped joint 10 formed by the tightly laid second layer of bricks. The mortise and tenon joint formed by the cross-shaped groove 5 and the cross-shaped joint 10 creates an interlocking connection between the bricks.

[0046] The brick arrangement for the fourth layer is the same as for the first. In terms of length and width, compared to the planar dimensions of the third layer, only one row / column is reduced in the middle of each of the long and short sides. The front, left, right, and back sides are each offset by 1 / 2 the distance of a shaped hollow concrete brick, aligning them centrally with the bricks of the third layer. During installation, a cross-shaped groove 5 is provided on the bottom surface of the shaped hollow concrete bricks. This groove is inserted into the cross-shaped joint 10 formed by the closely arranged bricks of the first layer. The mortise and tenon joint formed by the cross-shaped groove 5 and the cross-shaped joint 10 creates an interlocking connection between the bricks.

[0047] The fifth layer (the top layer) consists entirely of standard, tightly laid hollow concrete bricks 4. In terms of length and width, compared to the fourth layer's planar dimensions, only one row is reduced in the middle along the short side. The front, left, and right sides are offset by half the distance of a standard hollow concrete brick, and the backs are flush with the backs of the bricks in the first and third layers. During installation, cross-shaped grooves 5 are left on the bottom of the standard hollow concrete bricks. These grooves fit into the cross-shaped joints 10 formed by the tightly laid second layer of bricks. The mortise and tenon joints formed by the cross-shaped grooves 5 and the cross-shaped joints 10 create an interlocking structure. The back of the assembled concrete revetment structure has a concave-convex pattern, allowing it to interlock with the original soil layer during sand filling. The front, left, and right sides of the assembled concrete revetment are stepped, each step designed to protect against waves and erosion. Aquatic weed seeds can be sown on the steps and top surface, creating a green and ecological revetment.

[0048] This embodiment consists of end-shaped hollow concrete bricks 2, corner-shaped hollow concrete bricks 3, and universal-shaped hollow concrete bricks 4, which are tightly laid and stacked.
