Description

Technical Field

[0001] The present invention relates to the technical field of protective earth embankments, and in particular to a novel protective earth embankment and a deformation control method thereof. Background Art

[0002] A protective earth embankment is a embankment-like structure with protective functions built with earth as the main material. It is often used to resist disasters such as floods, wind and waves, and explosion impacts.

[0003] Traditional protective earth embankments often experience deformation and decreased stability over long periods of use due to soil pressure and external environmental factors. For example, geogrids, a crucial component of protective earth embankments, lack sufficient interlayer connection strength, leading to instability in the overall structure and compromising the stability of the embankment. Furthermore, deformation of the geogrids in existing protective earth embankments cannot be visually detected, making it difficult to identify the problem and implement timely measures, impacting the embankment's service life and effectiveness. Summary of the Invention

[0004] To solve the problems existing in the above background technology, the present invention is implemented through the following technical solutions: a new protective earth embankment and deformation control method thereof, comprising a foundation and several layers of unidirectional geogrids, wherein a layer of unidirectional geogrid 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 filled between adjacent unidirectional geogrids; a top layer of bidirectional geogrid is laid on the top of the earth embankment, and a filling layer is filled between the top bidirectional geogrid and the unidirectional geogrid below it; The filling layer is provided with earth bags on both sides along the width direction of the earth embankment, and multiple earth bags are stacked up and down to form a unit bag. The one-way geogrid wraps the unit bag from the outside upward on both sides along the width direction of the earth embankment and extends from the upper surface of the unit bag to the inside of the earth embankment. The outer surfaces of several of the stacked unit bags are paved with anti-skid nets, and the upper and lower sides of the anti-skid nets extend to the inside of the earth embankment. Both sides of the unidirectional geogrid in the width direction and both upper and lower sides of the anti-slip net are provided with connection structures.

[0005] Furthermore, the side of the unidirectional geogrid passes upward through the unidirectional geogrid above it or the top bidirectional geogrid, and then passes back through the filling layer, thereby forming an "O"-shaped cavity on the side of the unidirectional geogrid. The connecting structure of the side of the unidirectional geogrid is connecting rod 2, and connecting rod 2 is plugged into the "O"-shaped cavity.

[0006] Furthermore, the anti-skid net is a "C"-shaped structure, and the side edges of the two adjacent anti-skid nets are connected by a connecting structure. The connecting structure is a connecting piece, which fixes the side edges of the two anti-skid nets and the unidirectional geogrids and / or the top bidirectional geogrids stacked above and below the anti-skid nets.

[0007] Furthermore, the connecting piece consists of an L-shaped upper connecting body and a lower connecting body, the lower surface of the upper connecting body is provided with several plug rods, the lower ends of the plug rods are provided with hemispherical plugs, and the surface of the lower connecting body is provided with elastic slots, which are adapted to the hemispherical plugs.

[0008] Furthermore, a T-shaped fixed steel bar is installed between the anti-slip mesh and the earthbag; A fixing piece is installed in the middle of each layer of the unidirectional geogrid.

[0009] 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, and the deformation detection component is used to detect whether the unidirectional geogrid is deformed.

[0010] Furthermore, several groups of the deformation detection components are vertically arranged on the side of the anti-slip net and pre-buried in the control layer; The deformation detection assembly includes a top pipe and a plurality of unit pipes, the top pipe and the plurality of unit pipes are sequentially distributed from top to bottom, and a port is provided at the upper end of the top pipe; The unit pipe includes a detection tube, a detection hose and a connecting pipe. The side surface of the detection tube is provided with a side hole. The upper end of the detection hose is fixedly installed on the top pipe or the bottom end of the previous detection tube. The lower end is in an inverted "T" shape and is sealed in the next detection tube. The side of the detection hose is connected to the corresponding one-way geogrid. The connecting tube is located inside the detection tube, and the lower end of the connecting tube is sealed and slidably installed in the detection hose at the bottom end of the detection tube. The interior of the connecting tube is a through channel, and a block is fixedly provided on the outer surface of the connecting tube. The block corresponds to the side hole, and a connecting rod is provided between the connecting tube and the bottom end of the detection hose on its upper side.

[0011] Furthermore, the upper end of the internal channel of the communicating tube is a spherical opening.

[0012] Furthermore, the deformation control method is specifically as follows: Add liquid into the jacking pipe and observe whether liquid flows out of the side hole in the deformation detection assembly. If not, it is determined that the unidirectional geogrid is not deformed. If so, it is determined that the corresponding unidirectional geogrid is deformed. If the unidirectional geogrid is deformed, grouting reinforcement is adopted to fill and reinforce the corresponding layer of unidirectional geogrid until the deformation of the unidirectional geogrid of that layer is restored.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This new protective earth embankment and its deformation control method can effectively fix the side of the geogrid and strengthen the connection between the geogrid, the earthbag and the anti-slip net through the reverse design of the unidirectional geogrid and the earthbag, and the reverse design between the anti-slip net and the earthbag, thereby improving the stability of the overall structure of the protective earth embankment.

[0014] 2. This new protective earth embankment and its deformation control method are designed with a top 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 is deformed, the side hole is opened and liquid is added to the top pipe. If liquid flows out of the side hole, it can be determined that the corresponding unidirectional geogrid is deformed. This detection method is simple to operate and has accurate test results, and can promptly detect the deformation of the unidirectional geogrid. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The embodiments of the novel protective earth embankment and deformation control method thereof are as follows: See also Figures 1-14 , a new type of protective earth embankment and its deformation control method, the new type of protective earth embankment includes a foundation 1, several layers of unidirectional geogrids 3, a bottom layer of bidirectional geogrid 2 is laid inside the earth embankment, the bottom of the bottom bidirectional geogrid 2 is filled with gravel, and a filling layer is formed between the bottom bidirectional geogrid 2 and the unidirectional geogrid 3 above it. A layer of unidirectional geogrid 3 is laid on the surface of the foundation 1, and several layers of unidirectional geogrids 3 are laid in sequence from bottom to top. A filling layer is filled between adjacent unidirectional geogrids 3. A fixing part 5 is installed in the middle of each layer of unidirectional geogrid 3. Each layer of unidirectional geogrid 3 is composed of two unidirectional geogrids 3 spliced ​​together on the left and right. The two unidirectional geogrids 3 on the same layer are connected by a fixing part 5. The fixing part 5 is a connecting rod 1. The side edge of one unidirectional geogrid 3 passes through the other unidirectional geogrid 3 upward and then passes through downward, so that an "O"-shaped cavity is formed at the connection between the left and right unidirectional geogrids 3, and the connecting rod 1 is inserted and installed in the "O"-shaped cavity.

[0019] The top of the earth embankment is paved with a top bidirectional geogrid 8, and a filling layer is filled between the top bidirectional geogrid 8 and the unidirectional geogrid 3 below it. The filling layer and roadbed materials are laid above the top bidirectional geogrid 8.

[0020] The filling layer is provided with sandbags 4 on both sides along the width direction of the embankment. Multiple sandbags 4 are stacked up and down to form a unit bag. The one-way geogrid 3 wraps the unit bag from the outside upward on both sides along the width direction of the embankment and extends from the upper surface of the unit bag to the inside of the embankment, that is, every four layers of sandbags 4 wrap a layer of one-way geogrid 3. The outer surface of several stacked unit bags is paved with anti-skid nets 7. The anti-skid nets 7 are a three-dimensional mesh structure composed of a two-way grid and a three-layer folded net. The upper and lower side edges of the anti-skid nets 7 extend to the inside of the embankment, that is, the slope structure wrapped by the anti-skid nets 7; the two side edges in the width direction of the one-way geogrid 3 and the upper and lower side edges of the anti-skid nets 7 are provided with connecting structures 6, and T-shaped fixed steel bars 12 are installed between the anti-skid nets 7 and the sandbags 4.

[0021] Every four layers of earthbags 4 are inverted with a layer of unidirectional geogrid 3. After being tightened, the unidirectional geogrid 3 is secured to the ground with U-shaped nails. The remaining portion is filled and compacted. The lateral folds of the unidirectional geogrid 3 are connected to adjacent unidirectional geogrids 3 using connecting rods 62. Each layer of anti-slip mesh 7 is inverted at a length L (L is determined based on the longitudinal and transverse tensile strength of the anti-slip mesh 7 and the depth of the soil cover, and should be no less than 1000mm and no more than 4000mm). The bottom of the anti-slip mesh 7 is buried for a length M (M is no less than twice the width of the inverted earthbag 4). The effective folded length of the top of the anti-slip mesh 7 is M. The anti-slip mesh 7 is secured with fixing steel bars 12. The top of the fixing steel bars 12 consists of a 100mm*10mm*10mm steel bar in the horizontal direction and φ8 threaded steel bars in the longitudinal direction. The steel bars are welded to the steel bars. The fixed steel bars 12 are arranged with a horizontal spacing of S and a vertical spacing of N (N is an integer multiple of the geogrid pitch). The arrangement style is plum blossom pile type, and the anti-slip net 7 and the transverse ribs of the unidirectional geogrid 3 are tied together with steel wire ropes.

[0022] Example 1: The longitudinal and transverse tensile strength of the anti-slip mesh 7 is 6 kN / m. The width of the earthbags 4 is 500 mm. The pitch of the unidirectional geogrid 3 is 420 mm. The depth of the anti-slip mesh 7 covering the soil is 100 mm. Every four layers of earthbags 4 are covered with a layer of unidirectional geogrid 3. The unidirectional geogrid 3 is tightened and fixed to the ground with U-shaped nails. The remaining portion is filled and compacted. The folded portion of the unidirectional geogrid 3 is connected to the adjacent layer of unidirectional geogrid 3 with connecting rods 62. A layer of anti-slip mesh 7 is covered every 3000 mm. The bottom of the anti-slip mesh 7 is buried for 1000 mm, and the effective folded length of the top of the anti-slip mesh 7 is 1000 mm. The anti-slip mesh 7 is fixed with fixed steel bars 12. The top of the fixed steel bars 12 is a 100 mm*10 mm*10 mm steel bar in the horizontal direction and a φ8 threaded steel bar in the longitudinal direction. The steel bars and the steel bars are fixed by welding. The fixed steel bars 12 are arranged with a horizontal interval of 500 mm and a vertical interval of 420 mm in a plum blossom pile style, and the anti-slip net 7 and the transverse ribs of the unidirectional geogrid 3 are tied together with steel wire ropes.

[0023] Example 2: The longitudinal and transverse tensile strength of the anti-slip mesh 7 is 4 kN / m. The width of the earthbags 4 is 600 mm. The pitch of the unidirectional geogrid 3 is 320 mm. The depth of the anti-slip mesh 7 covering the soil is 50 mm. Every four layers of earthbags 4 are covered with a layer of unidirectional geogrid 3. The unidirectional geogrid 3 is tightened and fixed to the ground with U-shaped nails. The remaining part is filled and compacted. The folded portion of the unidirectional geogrid 3 is connected to the adjacent layer of unidirectional geogrid 3 with connecting rods 62. A layer of anti-slip mesh 7 is covered every 4000 mm. The bottom of the anti-slip mesh 7 is buried for 1200 mm, and the effective folded length of the top of the anti-slip mesh 7 is 1200 mm. The anti-slip mesh 7 is fixed with fixed steel bars 12. The top of the fixed steel bars 12 is a 100 mm*10 mm*10 mm steel bar in the horizontal direction and a φ8 threaded steel bar in the longitudinal direction. The steel bars and the steel bars are fixed by welding. The fixed steel bars 12 are arranged with a horizontal interval of 500 mm and a vertical interval of 320 mm in a plum blossom pile style, and the anti-slip net 7 and the transverse ribs of the unidirectional geogrid 3 are tied together with steel wire ropes.

[0024] 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 back through the filling layer, thereby 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 2 62, and the connecting rod 2 62 is inserted and installed in the "O"-shaped cavity.

[0025] It should also be noted that the anti-skid net 7 is a "C"-shaped structure, and the sides of the two adjacent anti-skid nets 7 are connected by a connecting structure 6. The connecting structure 6 is a connecting member 61. The connecting member 61 fixes the sides of the two anti-skid nets 7 and the unidirectional geogrids 3 and / or the top bidirectional geogrid 8 stacked above and below the anti-skid nets 7 together.

[0026] 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 plug rods, and the lower ends of the plug rods are provided with hemispherical plugs. The surface of the lower connector is provided with elastic slots, which are adapted to the hemispherical plugs. A spherical body is provided at the lower end of one side of the upper connector, and a spherical notch is opened on one side surface of the lower connector.

[0027] That is, the connector 61 consists of two parts: a plate with gourd-shaped grooves and mushroom-shaped grooves (the lower connector) and a plate with gourd-shaped protrusions and mushroom-shaped protrusions (the 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 snap into the grooves and will not be easily pulled 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-skid 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 be rotated. This eliminates the need to specifically align the grooves when placing the anti-skid net 7 and the unidirectional geogrid 3 between the two plates.

[0028] On this basis, 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, which is used to detect whether the unidirectional geogrid 3 is deformed.

[0029] It should be noted that several groups of deformation detection components are vertically arranged on the side of the anti-slip net 7 and pre-buried in the control layer 9; the deformation detection components include a top pipe 10 and a plurality of unit pipes 11, and the top pipe 10 and the plurality of unit pipes 11 are distributed in sequence from top to bottom, and each unit pipe 11 corresponds to a layer of unidirectional geogrid 3. A port is provided at the upper end of the top pipe 10, and a sealing cover is installed in the port. After the sealing cover is opened, liquid can be added to the top pipe 10.

[0030] The unit tube 11 includes a detection tube 111, a detection hose 112 and a connecting tube 113. A side hole 1111 is provided on the side surface of the detection tube 111. The upper end of the detection hose 112 is fixedly installed on the top pipe 10 or the bottom end of the previous detection tube 111, and the lower end is an inverted "T" shape and is sealed in the next detection tube 111. The side of the detection hose 112 is connected to the corresponding one-way geogrid 3. The anti-slip net 7 is a mesh structure. The side edges corresponding to the one-way geogrid 3 and the detection hose 112 are connected by a hard connecting rod. The hard connecting rod passes through the mesh holes on the surface of the anti-slip net 7 and is connected to the detection hose 112. One end of the hard connecting rod is installed on the surface of the one-way geogrid 3, and the other end can fit with the surface of the detection hose 112. The hard connecting rod and the detection hose 112 can be connected together by rolling and bundling.

[0031] The connecting tube 113 is located inside the detection tube 111. The lower end of the connecting tube 113 is sealed and slidably installed in the detection hose 112 at the bottom end of the detection tube 111. The interior of the connecting tube 113 is a through channel. A blocking block 1131 is fixedly provided on the outer surface of the connecting tube 113. The blocking block 1131 corresponds to the side hole 1111. A connecting rod 114 is provided between the connecting tube 113 and the bottom end of the detection hose 112 on its upper side.

[0032] When the unidirectional geogrid 3 is deformed, it will drive the corresponding detection hose 112 to move. The detection hose 112 will drive the connecting pipe 113 to move through the connecting rod 114, and the connecting pipe 113 will drive the blocking block 1131 to move, thereby opening the side hole 1111. At this time, 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 there is liquid flowing out of the side hole 1111, it can be determined whether the unidirectional geogrid 3 is deformed. At the same time, the liquid will enter the unit pipe 11 below through the channel in the connecting pipe 113. Therefore, the deformation of all unidirectional geogrids 3 can be detected.

[0033] It should be noted that the upper end of the internal channel of the connecting tube 113 is a spherical opening 1132. The design of the spherical opening 1132 facilitates liquid to enter the outer space of the connecting tube 113, and facilitates liquid outflow when the side hole 1111 is opened.

[0034] The deformation control method of the new protective earth embankment specifically includes: Add liquid to the jacking pipe 10 and observe whether liquid flows out of the side hole 1111 in the deformation detection assembly. If not, it is determined that the unidirectional geogrid 3 is not deformed. If so, it is determined that the corresponding unidirectional geogrid 3 is deformed. If the unidirectional geogrid 3 is deformed, grouting reinforcement is performed to the position of the unidirectional geogrid 3 of the corresponding layer until the deformation of the unidirectional geogrid 3 of this layer is restored.

[0035] The construction steps of the new protective earth embankment slope are as follows: S1. Excavate the base layer to the bottom bidirectional geogrid elevation 2: remove debris, excavate and level the base according to the bottom bidirectional geogrid elevation 2, and inspect the foundation bearing layer.

[0036] S2. Lay the first layer of anti-skid mesh 7: Cut the anti-skid mesh 7 as required and lay it in the specified position, leaving enough length for the anti-skid mesh 7 to be reversed. Secure the anti-skid mesh 7 and tighten it, then secure it with the fixing steel bars 12. Before nailing the fixing steel bars 12 in, tie the steel wire rope. After nailing in, use the steel wire rope to tie the anti-skid mesh 7 and the transverse ribs of the unidirectional geogrid 3 together. 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 be reversed. 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.

[0037] S4. Layered rolling and compacting of backfill soil: A certain amount of soil is placed on the one-way geogrid 3 and behind the earthbags 4. The free end of the grid is pulled into the grid using a tension beam and pressed with backfill soil. Soil is spread on the reinforcement to the specified thickness and compacted layer by layer until the next primary reinforcement layer is reached.

[0038] S5. Wrap the inverted unidirectional geogrid 3 around the earthbag 4 and lay it on the fill soil.

[0039] S6. Cut and position the unidirectional geogrid 3 as required, and connect this layer of unidirectional geogrid 3 with the reversed unidirectional geogrid 3 using the second connecting rod 62.

[0040] S7. Repeat steps S3-S6. When the length L is reached, use the anti-slip net 7 to reverse it. After tightening, fix the slope surface with fixed steel bars 12 and fix the unidirectional geogrid 3 and the anti-slip net 7 with connectors 61 at the reversed position.

[0041] S8. Repeat the above steps until the slope construction is completed.

[0042] S9. Lay the control layer 9 on the slope of the earth embankment. The control layer 9 is 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 with the corresponding detection hose 112, and then lay the control layer 9, and bury the deformation detection component in the control layer 9.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

8. The novel protective earth embankment and deformation control method thereof according to claim 7 is characterized in that: The upper end of the internal passage of the connecting tube (113) is a spherical opening (1132).

9. The novel protective earth embankment and deformation control method thereof according to claim 8 is characterized in that: The deformation control method is specifically as follows: Adding liquid into the jacking pipe (10) and observing whether liquid flows out of the side hole (1111) in the deformation detection component; if not, determining that the unidirectional geogrid (3) is not deformed; if so, determining that the corresponding unidirectional geogrid (3) is deformed; If the unidirectional geogrid (3) is deformed, grouting reinforcement is performed to the position of the unidirectional geogrid (3) of the corresponding layer until the deformation of the unidirectional geogrid (3) of the layer is restored.
