Description

Technical Field

[0001] This invention relates to the field of protective earthen embankment technology, specifically to a protective earthen embankment and its deformation control method. Background Technology

[0002] Protective earthen dikes are dike-like structures constructed primarily of earth, with protective functions, often used to resist disasters such as floods, waves, and explosive impacts.

[0003] Traditional protective earthen embankments often experience deformation and decreased stability during long-term use due to soil pressure and external environmental factors. For example, as an important component of protective earthen embankments, insufficient interlayer bonding strength of geogrids can lead to insufficient overall structural stability, affecting the embankment's robustness. Furthermore, deformation of geogrids in existing protective earthen embankments is not readily detectable, making it difficult to identify problems promptly and take timely measures, thus impacting the embankment's service life and protective effectiveness. Summary of the Invention

[0004] To address the problems existing in the above background technology, the present invention is implemented through the following technical solution: a protective earthen embankment and its deformation control method, comprising a foundation and several layers of unidirectional geogrids, wherein a layer of unidirectional geogrids is laid on the surface of the foundation, and several layers of unidirectional geogrids are laid sequentially from bottom to top, with a filling layer filling between adjacent unidirectional geogrids; a top layer of bidirectional geogrids is laid on the top of the earthen embankment, and a filling layer filling between the top layer of bidirectional geogrids and the unidirectional geogrids below it.

[0005] The filling layer is provided with soil bags on both sides along the width of the embankment. Multiple soil bags are stacked on top of each other to form a unit bag. The unidirectional geogrid wraps around the unit bag from the outside to the top along both sides along the width of the embankment and extends from the upper surface of the unit bag into the interior of the embankment. The outer surface of the stacked unit bags is covered with anti-slip netting, and the upper and lower sides of the anti-slip netting extend into the interior of the embankment.

[0006] The unidirectional geogrid has connecting structures on both sides in the width direction and on both sides of the anti-slip net.

[0007] Furthermore, the side of the unidirectional geogrid passes upward through the unidirectional geogrid above it or the top bidirectional geogrid, and then passes downward back through the filling layer, thereby forming an "O" shaped cavity on the side of the unidirectional geogrid. The connecting structure on the side of the unidirectional geogrid is a second connecting rod, which is inserted into the "O" shaped cavity.

[0008] Furthermore, the anti-slip net has a "C" shaped structure, and the sides of two adjacent anti-slip nets are connected by a connecting structure, which is a connector. The connector fixes the sides of the two anti-slip nets together with the unidirectional geogrid and / or the top bidirectional geogrid superimposed on the anti-slip nets.

[0009] Furthermore, the connector is composed of an L-shaped upper connector and a lower connector. The lower surface of the upper connector is provided with several inserts, and the lower end of each insert is provided with a hemispherical plug. The surface of the lower connector is provided with an elastic slot that is adapted to the hemispherical plug.

[0010] Furthermore, T-shaped fixing steel bars are installed between the anti-slip net and the soil bag;

[0011] A fastener is installed in the middle of each layer of the unidirectional geogrid.

[0012] Furthermore, a control layer is laid on the surface of the anti-slip net, and a deformation detection component is installed in the control layer to detect whether the unidirectional geogrid is deformed.

[0013] Furthermore, several sets of the deformation detection components are vertically arranged on the side of the anti-slip net and pre-embedded in the control layer;

[0014] The deformation detection component includes a jacking pipe and multiple unit pipes, which are arranged sequentially from top to bottom. The upper end of the jacking pipe is provided with a port.

[0015] The unit tube includes a detection tube, a detection hose, and a connecting tube. The side surface of the detection tube has a side hole. The upper end of the detection hose is fixedly installed on the bottom end of the top tube or the previous detection tube, and the lower end is inverted "T" shape and sealed in the next detection tube. The side of the detection hose is connected to the corresponding unidirectional geogrid.

[0016] The connecting tube is located inside the detection tube. The lower end of the connecting tube is slidably and sealed in the detection hose at the bottom of the detection tube. The interior of the connecting tube is a through channel. A plug is fixedly provided on the outer surface of the connecting tube. The plug corresponds to the side hole. A connecting rod is provided between the bottom end of the connecting tube and the detection hose on its upper side.

[0017] Furthermore, the upper end of the internal channel of the connecting pipe is a spherical opening.

[0018] Furthermore, the deformation control method specifically includes:

[0019] Add liquid to the jacking pipe and observe whether liquid flows out from the side hole of the deformation detection component. If no liquid flows out, it is determined that the unidirectional geogrid is not deformed. If liquid flows out, it is determined that the corresponding unidirectional geogrid is deformed.

[0020] If the uniaxial geogrid is deformed, grouting reinforcement is used to fill and reinforce the corresponding layer of uniaxial geogrid until the deformation of that layer of uniaxial geogrid is restored.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The protective earthen embankment and its deformation control method, through the reverse wrapping design of unidirectional geogrid and soil bags, as well as the reverse wrapping design between anti-slip net and soil bags, can effectively fix the sides of the geogrid, enhance the connection between the geogrid, soil bags and anti-slip net, thereby improving the overall stability of the protective earthen embankment structure.

[0023] 2. The protective embankment and its deformation control method utilize the design of a jacking pipe and multiple unit pipes in the deformation detection component. The side of the detection hose in the unit pipe is connected to the corresponding unidirectional geogrid. When the unidirectional geogrid deforms, the side hole is opened, and liquid is added to the jacking pipe. If liquid flows out of the side hole, it can be determined that the corresponding unidirectional geogrid has deformed. This detection method is simple to operate, provides accurate detection results, and can promptly detect the deformation of the unidirectional geogrid. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] An example of the protective earthen embankment and its deformation control method is as follows:

[0041] Please see Figures 1-14A protective earthen embankment and its deformation control method are disclosed. The protective earthen embankment includes a foundation 1 and several layers of unidirectional geogrids 3. A bottom layer of bidirectional geogrids 2 is laid inside the embankment. Crushed stone is filled below the bottom layer of bidirectional geogrids 2. A filling layer is formed between the bottom layer of bidirectional geogrids 2 and the unidirectional geogrids 3 above it. A layer of unidirectional geogrids 3 is laid on the surface of the foundation 1. Several layers of unidirectional geogrids 3 are laid sequentially from bottom to top. A filling layer is filled between adjacent unidirectional geogrids 3. A fixing member 5 is installed in the middle of each layer of unidirectional geogrids 3. Each layer of unidirectional geogrids 3 is composed of two unidirectional geogrids 3 spliced ​​together from left to right. The two unidirectional geogrids 3 in the same layer are connected by the fixing member 5, which is a connecting rod. The side of one unidirectional geogrid 3 passes upward through the other unidirectional geogrid 3 and then downward, so that the connection between the two unidirectional geogrids 3 forms an "O" shaped cavity. The connecting rod is inserted into the "O" shaped cavity.

[0042] The top of the embankment is covered with a top layer of bidirectional geogrid 8, and a filling layer is placed between the top layer of bidirectional geogrid 8 and the unidirectional geogrid 3 below it. The filling layer and subgrade material are laid on top of the top layer of bidirectional geogrid 8.

[0043] Soil bags 4 are set on both sides of the filling layer along the width of the embankment. Multiple soil bags 4 are stacked one on top of the other to form a unit bag. The unidirectional geogrid 3 wraps around the unit bag from the outside to the top along both sides of the width of the embankment and extends from the upper surface of the unit bag into the interior of the embankment. That is, every four layers of soil bags 4 wrap one layer of unidirectional geogrid 3. The outer surface of several stacked unit bags is covered with anti-slip net 7. The anti-slip net 7 is a three-dimensional mesh structure composed of bidirectional geogrid and three layers of folded net. The upper and lower sides of the anti-slip net 7 extend into the interior of the embankment, that is, the slope structure of the anti-slip net 7 wrapping. The unidirectional geogrid 3 and the anti-slip net 7 are provided with connecting structures 6 on both sides of the width direction and the upper and lower sides of the anti-slip net 7. T-shaped fixing steel bars 12 are installed between the anti-slip net 7 and the soil bags 4.

[0044] Every four layers of soil bags 4 are wrapped with a layer of unidirectional geogrid 3. After the unidirectional geogrid 3 is tightened, it is fixed to the ground with U-shaped nails. The remaining part is filled with soil and compacted. The side fold-back part of the unidirectional geogrid 3 is connected to the adjacent unidirectional geogrid 3 with connecting rod 2 62. Every length L (L is determined according to the longitudinal and transverse tensile strength of the anti-slip net 7 and the soil cover depth, not less than 1000mm and not more than 4000mm) a layer of anti-slip net 7 is wrapped. The bottom of the anti-slip net 7 is buried with a length M (M is not less than twice the width of the wrapped soil bag 4). The effective fold-back length of the top of the anti-slip net 7 is M. The anti-slip net 7 is fixed with fixing steel bars 12. The top of the fixing steel bars 12 is a horizontal 100mm*10mm*10mm steel bar, and the longitudinal part is a φ8 threaded steel bar. The steel bars are fixed to the steel bars by welding. The fixed reinforcing bars 12 are arranged with a transverse spacing of S and a longitudinal spacing of N (N is an integer multiple of the geogrid pitch). The arrangement pattern is a plum blossom pile, and the anti-slip net 7 and the transverse ribs of the unidirectional geogrid 3 are tied together with steel wire rope.

[0045] Example 1: The longitudinal and transverse tensile strength of the anti-slip net 7 is 6kN / m, the width of the soil bag 4 is 500mm, the pitch of the unidirectional geogrid 3 is 420mm, and the soil covering depth of the anti-slip net 7 is 100mm. Every four layers of soil bags 4 are wrapped around a layer of unidirectional geogrid 3. After the unidirectional geogrid 3 is tightened, it is fixed to the ground with U-shaped nails. The remaining part is filled with soil and compacted. The folded-back portion of the unidirectional geogrid 3 is connected to the adjacent layer of unidirectional geogrid 3 with connecting rod 62. Every 3000mm, a layer of anti-slip net 7 is wrapped around the net. The bottom of the anti-slip net 7 is buried for 1000mm, and the effective folded-back length of the top of the anti-slip net 7 is 1000mm. The anti-slip net 7 is fixed with fixing steel bars 12. The top of the fixing steel bars 12 is a horizontal 100mm*10mm*10mm steel bar, and the longitudinal part is a φ8 threaded steel bar. The steel bars are welded to the steel bars. The fixed reinforcing bars 12 are arranged with a horizontal spacing of 500mm and a vertical spacing of 420mm, in a plum blossom pile pattern, and the anti-slip net 7 and the transverse ribs of the unidirectional geogrid 3 are tied together with steel wire rope.

[0046] Example 2: The longitudinal and transverse tensile strength of the anti-slip net 7 is 4kN / m, the width of the soil bag 4 is 600mm, the pitch of the unidirectional geogrid 3 is 320mm, and the soil covering depth of the anti-slip net 7 is 50mm. Every four layers of soil bags 4 are wrapped around a layer of unidirectional geogrid 3. After the unidirectional geogrid 3 is tightened, it is fixed to the ground with U-shaped nails. The remaining part is filled with soil and compacted. The folded-back portion of the unidirectional geogrid 3 is connected to the adjacent layer of unidirectional geogrid 3 with connecting rod 62. Every 4000mm, a layer of anti-slip net 7 is wrapped around the net. The bottom of the anti-slip net 7 is buried for 1200mm, and the effective folded-back length of the top of the anti-slip net 7 is 1200mm. The anti-slip net 7 is fixed with fixing steel bars 12. The top of the fixing steel bars 12 is a horizontal 100mm*10mm*10mm steel bar, and the longitudinal part is a φ8 threaded steel bar. The steel bars are welded to the steel bars. The fixed reinforcing bars 12 are arranged with a horizontal spacing of 500mm and a vertical spacing of 320mm, in a plum blossom pile pattern, and the anti-slip net 7 and the transverse ribs of the unidirectional geogrid 3 are tied together with steel wire rope.

[0047] It should be noted that the side of the unidirectional geogrid 3 passes upward through the unidirectional geogrid 3 above it or the top bidirectional geogrid 8, and then passes downward back through the filling layer, thus forming an "O" shaped cavity on the side of the unidirectional geogrid 3. The connecting structure 6 on the side of the unidirectional geogrid 3 is a connecting rod 62, which is inserted into the "O" shaped cavity.

[0048] It should also be noted that the anti-slip net 7 has a "C" shaped structure. The sides of two adjacent anti-slip nets 7 are connected by a connecting structure 6. The connecting structure 6 is a connector 61, which fixes the sides of the two anti-slip nets 7 together with the unidirectional geogrid 3 and / or the top bidirectional geogrid 8 superimposed on the anti-slip nets 7.

[0049] The connector 61 consists of an L-shaped upper connector and a lower connector. The lower surface of the upper connector is provided with several inserts, and the lower end of each insert is provided with a hemispherical plug. The surface of the lower connector is provided with a flexible slot that is compatible with the hemispherical plug. The lower end of one side of the upper connector is provided with a spherical body, and one side surface of the lower connector is provided with a spherical notch.

[0050] That is, connector 61 consists of two parts: a plate with gourd-shaped and mushroom-shaped grooves (lower connector) and a plate with gourd-shaped and mushroom-shaped protrusions (upper connector). The upper connector can be snapped into the lower connector like a buckle. The gourd and mushroom shapes ensure that the protrusions can easily fit into the grooves and will not easily pull out. Each mushroom-shaped protrusion has two buckles, which, together with the gourd-shaped protrusions, can accommodate the thickness variation between the geogrid and the anti-slip net 7. The gourd-shaped protrusions and the small notch at one end of the lower connector ensure that after one side of the gourd-shaped protrusion of the upper connector is snapped in, the other side can rotate. This way, when the anti-slip net 7 and the unidirectional geogrid 3 are placed between the two plates, it is not necessary to specifically align the grooves.

[0051] Based on this, a control layer 9 is laid on the surface of the anti-slip net 7, and a deformation detection component is installed in the control layer 9 to detect whether the unidirectional geogrid 3 is deformed.

[0052] It should be noted that several sets of deformation detection components are vertically arranged on the side of the anti-slip net 7 and pre-embedded in the control layer 9; the deformation detection components include a jacking pipe 10 and multiple unit pipes 11, which are distributed from top to bottom. Each unit pipe 11 corresponds to a layer of unidirectional geogrid 3. The upper end of the jacking pipe 10 is provided with a port, and a cap is installed in the port. After the cap is opened, liquid can be added to the jacking pipe 10.

[0053] Unit pipe 11 includes detection pipe 111, detection hose 112, and connecting pipe 113. The side surface of detection pipe 111 has a side hole 1111. The upper end of detection hose 112 is fixedly installed on the bottom end of the top pipe 10 or the previous detection pipe 111, and the lower end is inverted "T" shape and sealed in the next detection pipe 111. The side of detection hose 112 is connected to the corresponding unidirectional geogrid 3. Anti-slip net 7 has a mesh structure. The side of unidirectional geogrid 3 corresponding to detection hose 112 is connected by a rigid connecting rod. The rigid connecting rod passes through the mesh of the anti-slip net 7 and is connected to the detection hose 112. One end of the rigid connecting rod is installed on the surface of unidirectional geogrid 3, and the other end can fit against the surface of detection hose 112. The rigid connecting rod and detection hose 112 can be connected together by binding with a strap.

[0054] The connecting pipe 113 is located inside the detection pipe 111. The lower end of the connecting pipe 113 is slidably and sealed in the detection hose 112 at the bottom of the detection pipe 111. The interior of the connecting pipe 113 is a through channel. A plug 1131 is fixedly provided on the outer surface of the connecting pipe 113. The plug 1131 corresponds to the side hole 1111. A connecting rod 114 is provided between the bottom end of the connecting pipe 113 and the detection hose 112 above it.

[0055] When the uniaxial geogrid 3 deforms, it will cause the corresponding detection hose 112 to move. The detection hose 112 drives the connecting pipe 113 to move through the connecting rod 114. The connecting pipe 113 drives the block 1131 to move, thereby opening the side hole 1111. When liquid is added to the top pipe 10, the liquid will flow into the space outside the connecting pipe 113 in the detection pipe 111 when it flows through the unit pipe 11, and then flow out from the side hole 1111. By observing whether liquid flows out from the side hole 1111, it can be determined whether the uniaxial geogrid 3 has deformed. At the same time, the liquid will enter the lower unit pipe 11 through the channel in the connecting pipe 113. Therefore, the deformation of all uniaxial geogrids 3 can be detected.

[0056] It should be noted that the upper end of the internal channel of the connecting pipe 113 is a spherical opening 1132. By designing the spherical opening 1132, it is easy for liquid to enter the outer space of the connecting pipe 113, and when the side hole 1111 is opened, it is easy for liquid to flow out.

[0057] The specific methods for controlling the deformation of protective earthen embankments include:

[0058] Add liquid to the jacking pipe 10 and observe whether liquid flows out at the side hole 1111 in the deformation detection component. If not, it is determined that the unidirectional geogrid 3 is not deformed. If it is, it is determined that the corresponding unidirectional geogrid 3 is deformed.

[0059] If the uniaxial geogrid 3 deforms, grouting reinforcement is used to fill and reinforce the corresponding layer of uniaxial geogrid 3 until the deformation of the uniaxial geogrid 3 in that layer is restored.

[0060] The construction steps for the protective earthen embankment slope are as follows:

[0061] S1. Excavation from base course to bottom bidirectional geogrid 2 elevation: Remove debris, excavate and level the base according to bottom bidirectional geogrid 2 elevation, and inspect the foundation bearing layer.

[0062] S2. Laying the first layer of anti-slip netting 7: Cut the anti-slip netting 7 as required, lay it in the specified position, and reserve the length required for the anti-slip netting 7 to wrap around itself. Fix the anti-slip netting 7 and tighten it, using fixing steel bars 12 for securement. Before nailing in the fixing steel bars 12, tie them with wire ropes. After nailing in, use wire ropes to tie the anti-slip netting 7 and the transverse ribs of the unidirectional geogrid 3 together.

[0063] S3. Laying the first layer of unidirectional geogrid 3: Cut out the unidirectional geogrid 3 as required, lay it in the specified position, and reserve the length required for the unidirectional geogrid 3 to wrap around. Unfold the unidirectional geogrid 3 smoothly, tighten it to avoid wrinkles, and fix it to the ground with U-shaped nails every 1.5m-2m.

[0064] S4. Layered compaction of backfill soil: A certain amount of soil is laid on the uniaxial geogrid 3 and behind the soil bag 4. The other free end of the geogrid is pulled into the geogrid by a tension beam and pressed on with backfill soil. Soil is laid on the reinforcement to the specified thickness, and compacted in layers until the next main reinforcement layer is reached.

[0065] S5. Wrap the unidirectional geogrid 3 around the soil bag 4 and lay it on the backfill.

[0066] S6. Cut and position the unidirectional geogrid 3 as required, and use connecting rod 262 to connect this layer of unidirectional geogrid 3 to the reverse-wrapped unidirectional geogrid 3.

[0067] S7. Repeat steps S3-S6. When the length L is reached, use the anti-slip net 7 to wrap around the slope. After tightening, use the fixing steel bar 12 to fix the slope. Use the connector 61 to fix the unidirectional geogrid 3 and the anti-slip net 7 at the wrapping point.

[0068] S8. Repeat the above steps until the slope construction is completed.

[0069] S9. Lay a control layer 9 on the slope of the embankment. The control layer 9 consists of planting soil and planting turf. Before laying the control layer 9, install the deformation detection component on the surface of the anti-slip net 7, connect the unidirectional geogrid 3 to the corresponding detection hose 112, and then lay the control layer 9 and bury the deformation detection component in the control layer 9.
