Description

Technical Field

[0001] This invention relates to the field of riverbank protection technology, and in particular to an ecologically resilient revetment structure for canals and its construction method. Background Technology

[0002] With the booming development of inland waterway transportation in my country and the trend towards larger and faster ships, the hydrodynamic effect of ships in canals is increasingly enhanced. The waves generated by frequent ship traffic and the corresponding changes in water flow alter the original hydrodynamic conditions of the waterway, constantly impacting the riverbank revetment structures and posing a potential threat of erosion damage and even structural instability. Currently, while existing revetment structures can withstand frequent hydrodynamic impacts, they suffer from drawbacks such as complex structural forms and high operational and maintenance difficulties. Furthermore, existing revetment structures often do not consider the actual canal length and project scale, extensively using high-precision devices such as mechanical gears or waterwheels. Large-scale use in actual projects would be prohibitively expensive and does not meet economic requirements. Therefore, the selection of revetment type is extremely important. It must not only ensure the stability, safety, and economy of the bank slope and withstand frequent impacts, but also meet ecological requirements, integrating the revetment structure with the surrounding environment.

[0003] Therefore, there is an urgent need to develop an ecologically resilient revetment structure and its construction method for canals that not only meets the requirements of high toughness and ecological greenness, but also ensures a certain degree of economic efficiency and can be applied to practical engineering projects. Summary of the Invention

[0004] The purpose of this invention is to provide an ecologically resilient revetment structure for canal channels and its construction method, thereby overcoming the shortcomings of existing revetment structures, such as complexity, difficulty in operation and maintenance, and inability to meet economic requirements if used on a large scale in actual projects.

[0005] To achieve the above objectives, the present invention provides an ecologically resilient revetment structure for a canal, comprising: an earthen slope, which is set on the bank of the canal, the earthen slope sloping outward from bottom to top, the top surface of the earthen slope having a bank top plane, and the inner side of the bank top plane sloping outward from top to bottom; a retaining wall, which is set between the canal and the lower end of the earthen slope, the outer side of the retaining wall sloping outward from top to bottom, and the length of the retaining wall being distributed along the length direction of the canal; grouting anchors, with multiple grouting anchors spaced apart within the earthen slope; a plain concrete soil stabilization layer, the surface of the earthen slope being covered with the plain concrete soil stabilization layer; a intercepting ditch, the bank top plane having an intercepting ditch along the length direction of the canal, the bank top plane having multiple evenly distributed collection pits along the length direction of the intercepting ditch, the top of the collection pits communicating with the intercepting ditch; and drainage pipes, the surface of the plain concrete soil stabilization layer having multiple evenly distributed drainage pipes along the direction of the canal. The upper end of the drainage pipe corresponding to the sump is connected to the corresponding sump, and the upper ends of the remaining drainage pipes are sealed with end caps. The lower end of each drainage pipe passes through the retaining wall and connects to the river channel. Multiple interlocking blocks are laid on the surface of the plain concrete stabilization layer. The blocks are installed between the outer side of the retaining wall and the inner side of the bank top plane. Each block is H-shaped, and the top surface of the middle plane of the block has a recessed groove that is larger at the top and smaller at the bottom. A water pipe pre-drilled hole is provided at the bottom of the groove. When splicing, the multiple blocks are distributed in a matrix. The bottom of the H-shape formed by splicing the blocks from bottom to top in each column forms an installation channel distributed along the vertical direction. A drainage pipe is installed in each installation channel, and a connecting pipe connected to the drainage pipe is provided in each water pipe pre-drilled hole. A reinforcement layer is poured between the surface of the plain concrete stabilization layer and the blocks.

[0006] Preferably, in the above technical solution, the groove is a frustum-shaped structure that is larger at the top and smaller at the bottom.

[0007] Preferably, in the above technical solution, vegetation is planted in the groove of the block located on the upper part of the slope, and each groove planted with vegetation is provided with a filter screen, stone chips, geotextile and planting soil in sequence from bottom to top.

[0008] Preferably, in the above technical solution, each block includes two H-shaped half blocks that are spliced ​​together vertically, and the block is divided into two H-shaped half blocks along the axial direction of the groove.

[0009] Preferably, in the above technical solution, on every four blocks that are spliced ​​together and whose splice joints are cross-shaped, a connecting rod is provided in the middle of the cross-shaped splice joint. The axis of the connecting rod is perpendicular to the axis of the water pipe reserved hole of the block. The upper and lower sides of each block are recessed with connecting grooves for installing the connecting rod at positions corresponding to the connecting rod.

[0010] Preferably, in the above technical solution, the intercepting ditch between two adjacent water collection pits is inclined downward from the middle to the two corresponding water collection pits.

[0011] A construction method for an ecologically resilient revetment structure for a canal includes the following steps:

[0012] (1) First, the slope of the earth slope is excavated and trimmed and the retaining wall is constructed. The earth slope is initially excavated according to the design slope of the earth slope. Then, the retaining wall is positioned according to the design dimensions of the retaining wall and the excavation dimensions at the bottom of the retaining wall are determined. Finally, the retaining wall is constructed. After the retaining wall is constructed, the gap between the retaining wall and the earth slope is backfilled. Finally, the earth slope is trimmed to ensure that the slope of the earth slope meets the design slope.

[0013] (2) After the slope is repaired, grouting anchor rod construction is carried out. Grouting anchor rods are driven into the slope and grouting is performed. After the grouting anchor rod construction is completed, plain concrete soil stabilization layer is poured.

[0014] (3) On the plain concrete soil layer, water pipe fixing brackets are pre-installed according to the installation position of the blocks to determine the position of the drainage pipes. The distance between two adjacent drainage pipes is equal to the distance between the water pipe reserved holes of two adjacent blocks along the river direction. The drainage pipes are installed on the water pipe fixing brackets, and a connecting pipe connected to the drainage pipe is installed at the position corresponding to the water pipe reserved hole of the corresponding block. The lower end of the drainage pipe passes through the retaining wall and connects to the river.

[0015] (4) Lay the blocks according to the location of the connecting pipe, and fit the water pipe reserved hole of the block onto the corresponding connecting pipe; during construction, start laying the blocks from the bottom of the slope upwards.

[0016] (5) The bottom of the H-shape formed by laying each row of blocks from bottom to top forms an installation channel distributed in the vertical direction, which is used to accommodate the drainage pipe.

[0017] (6) After the blocks are laid, concrete is poured through the installation channel to form a reinforcement layer.

[0018] (7) After the reinforcement layer is completed, the top surface of the slope, the intercepting ditch and the sump are constructed. Finally, according to the position of the top intercepting ditch and the sump, the upper end of the drainage pipe corresponding to the sump is extended upward to the bottom of the corresponding sump and connected to the sump; the upper end of the remaining drainage pipes is sealed with end caps.

[0019] Preferably, in the above technical solution, in step (4), each block includes two H-shaped half blocks that are spliced ​​together vertically. The block is divided into two H-shaped half blocks along the axial direction of the groove. On every four blocks that are spliced ​​together with a cross-shaped joint, a connecting rod is provided in the middle of the cross-shaped joint. The axis of the connecting rod is perpendicular to the axis of the water pipe reserved hole of the corresponding block. The upper and lower sides of each block are recessed with connecting grooves at the positions corresponding to the connecting rods. When the blocks are laid, mortar is used to lay between the two H-shaped half blocks of each block, between the block and the retaining wall, and between the block and the top plane of the bank. The remaining blocks are connected with mortar using connecting rods.

[0020] Preferably, in the above technical solution, before step (6), the area to be planted with vegetation is determined according to the water level of the river. The vertical distance between the block to be planted and the water level is greater than 2m. In the groove of the block to be planted with vegetation, a filter screen, stone chips, geotextile and planting soil are set from bottom to top, and finally the vegetation is planted.

[0021] Preferably, in the above technical solution, in step (7), a water collection pit is set every 20m along the length of the intercepting ditch. The length, width and height of the water collection pit are all 1m. The intercepting ditch between two adjacent water collection pits is set downward from the middle to the two corresponding water collection pits, and the slope of the intercepting ditch is 5%. The upper end of the drain pipe corresponding to the water collection pit is connected to the lower part of the corresponding water collection pit.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The block of the present invention is H-shaped, with the protruding parts at both ends directly contacting and colliding with the water waves, which can effectively dissipate and absorb the energy of the water waves and play a role in preventing erosion; the middle part of the block is designed as a groove that is larger at the top and smaller at the bottom, and the lower part of the groove is connected to the drainage pipe through a connecting pipe, which plays a role in collecting and draining water, and can also eliminate some of the energy of the water waves. It has good stability, high safety performance, simple structure, does not use any mechanical equipment or embedded components that require frequent maintenance, has low operation and maintenance difficulty, can be used on a large scale in actual projects, and meets the requirements of economy;

[0024] 2. The H-shaped blocks of this invention not only give the revetment structure excellent mechanical properties such as high toughness and impact resistance, but also ensure that the revetment structure has strong overall stability and safety. The protruding sides and the groove in the middle, which is larger at the top and smaller at the bottom, enable the H-shaped blocks to have the functions of energy absorption and energy dissipation as well as drainage. In addition, green plants can be planted in the grooves, which meets the requirements of green ecology and is low-carbon and environmentally friendly.

The revetment structure includes an earth slope 12, a retaining wall 13, grouting anchors 11, a plain concrete soil stabilization layer 7, a water interception ditch 9, a drainage pipe 14, masonry blocks 3, and a reinforcement layer 6.

[0039] refer to Figures 1 to 7An earthen slope 12 is situated on the bank of the river channel 1, sloping outwards from bottom to top. The top surface of the earthen slope 12 has a bank top plane, and the inner side of the bank top plane slopes outwards from top to bottom towards the outside of the river channel to facilitate the subsequent installation of masonry blocks 3. A retaining wall 13 is positioned between the river channel 1 and the lower end of the earthen slope 12. The outer side of the retaining wall 13 slopes outwards from top to bottom to facilitate the subsequent installation of masonry blocks 3, and the length of the retaining wall 13 is distributed along the length of the river channel 1 to prevent the earthen slope 12 from collapsing and to prevent the upper masonry blocks 3 from slipping during construction and operation. Multiple spaced grouting anchors 11 are installed within the earthen slope 12 to enhance the stability and durability of the strata. A plain concrete soil stabilization layer 7 is laid on the surface of the earthen slope 12 to stabilize the soil and prevent the earthen slope 12 from collapsing.

Each installation channel contains a drainage pipe 14, and each water pipe pre-drilled hole 16 contains a connecting pipe 5 connected to the drainage pipe 14. For ease of connection, the connecting pipe 5 is a T-shaped structure. The middle part of the block 3 is designed as a groove 19 that is larger at the top and smaller at the bottom.

It plays the role of drainage and can also eliminate some of the energy of water waves. It has good stability and high safety performance. Green plants can be planted in the groove 19 to meet the requirements of green ecology.A reinforcing layer 6 is poured between the surface of the plain concrete soil stabilization layer 7 and the masonry block 3 to fix the drainage pipe 14 and the masonry block 3, and to further reinforce the soil slope 12.

Finally, the earth slope is trimmed to ensure that the slope of the earth slope meets the design slope. (2) After the slope is repaired, grouting anchor rod construction is carried out. Grouting anchor rods are driven into the slope and grouting is performed. After the grouting anchor rod construction is completed, plain concrete soil stabilization layer is poured. (3) On the plain concrete soil layer, water pipe fixing brackets are pre-installed according to the installation position of the blocks to determine the position of the drainage pipe. The distance between two adjacent drainage pipes is equal to the distance between the water pipe reserved holes of two adjacent blocks along the river direction. The drainage pipe is installed on the water pipe fixing bracket, and a connecting pipe connected to the drainage pipe is installed at the position corresponding to the water pipe reserved hole of the corresponding block. The lower end of the drainage pipe passes through the retaining wall and connects to the river. (4) Lay the blocks according to the location of the connecting pipe, and fit the water pipe reserved hole of the block onto the corresponding connecting pipe; during construction, start laying the blocks from the bottom of the slope upwards. (5) The bottom of the H-shape formed by laying the blocks from bottom to top in each row forms an installation channel distributed in the vertical direction, which is used to accommodate the drainage pipe; (6) After the blocks are laid, concrete is poured through the installation channel to form a reinforcement layer; (7) After the reinforcement layer is completed, the top surface of the slope, the intercepting ditch and the sump are constructed. Finally, according to the position of the top intercepting ditch and the sump, the upper end of the drainage pipe corresponding to the sump is extended upward to the bottom of the corresponding sump and connected to the sump; the upper end of the remaining drainage pipes is sealed with end caps.

4. The construction method of the ecologically resilient revetment structure for canal channels according to claim 3, characterized in that, In step (4), each block includes two H-shaped half blocks that are spliced ​​together vertically along the slope. The block is divided into two H-shaped half blocks along the axis of the groove. A connecting rod is provided in the middle of the cross-shaped splice on every four blocks that are spliced ​​together. The axis of the connecting rod is perpendicular to the axis of the water pipe reserved hole of the corresponding block. A connecting groove is recessed on the upper and lower sides of each block at the position corresponding to the connecting rod. When the blocks are laid, mortar is used to lay between the two H-shaped half blocks of each block, between the block and the retaining wall, and between the block and the top plane of the bank. The remaining blocks are connected with mortar using connecting rods.

5. The construction method of the ecologically resilient revetment structure for canal channels according to claim 3, characterized in that, Before step (6), determine the area to be planted with vegetation based on the water level of the river. The vertical distance between the blocks to be planted and the water level is greater than 2m. In the groove of the blocks to be planted with vegetation, filter screen, stone chips, geotextile and planting soil are set from bottom to top, and finally the vegetation is planted.

6. The construction method of the ecologically resilient revetment structure for canal channels according to claim 3, characterized in that, In step (7), a water collection pit is set every 20m along the length of the intercepting ditch. The length, width and height of the water collection pit are all 1m. The intercepting ditch between two adjacent water collection pits is set downward from the middle to the two corresponding water collection pits, and the slope of the intercepting ditch is 5%. The upper end of the drain pipe corresponding to the water collection pit is connected to the lower part of the corresponding water collection pit.
