In order to consider the economic feasibility of island expansion projects, sand-blowing ships are generally used to carry out island and reef construction. Therefore, calcareous sand is the main raw material for islands and reefs. There are significant differences between calcareous sand and traditional natural river sand in terms of structural strength and crushing performance. Calcium sand is calcified after the death of corals and other shellfish. It has low strength and various shapes. It is very easy to break in engineering. The crushing of calcareous sand will inevitably affect the foundation of islands and reefs, and then cause disasters such as settlement of upper buildings. In addition, islands and reefs are significantly affected by ocean tides and have abundant groundwater seepage. The poor gradation of calcareous sand after crushing is very easy to migrate under seepage conditions, causing foundation cavities and affecting foundation stability. Therefore, in order to ensure the long-term stability and safety of island and reef projects, it is necessary to reinforce the islands and reefs. In the existing technology, whether it is cement-soil mixing piles or cement injection methods, large-scale engineering construction is required, which will have a great impact on the island and reef environment, and the construction period and cost are relatively high, which is not conducive to long-term maintenance.

[0031] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1

[0034] Reference Figure 1 and Figure 7 , which is the first embodiment of the present invention. This embodiment provides a calcareous sand island reef foundation reinforcement structure based on seepage and a construction method thereof. The calcareous sand island reef foundation reinforcement structure based on seepage includes a seepage component 100 and an adjustment component 200. The seepage component 100 is used to introduce microorganisms into groundwater, and introduce the microorganisms into the gaps in the calcareous sand through its seepage to carry out calcification reaction to fill and reinforce the foundation. At the same time, through the setting of the adjustment component 200, the position and amount of the microorganisms introduced into the groundwater can be freely adjusted, which greatly improves the scope and controllability of calcification.

[0035] Specifically, the regulating tube 102 is located inside the seepage tube 101, the temperature control tube 103 is fixed on the outside of the regulating tube 102, seepage holes S1 are opened on both sides of the seepage tube 101, connecting holes S2 matching therewith are opened on both sides of the regulating tube 102, the fixed tube 104 is fixed on the inside of the seepage hole S1, the closing piece 105 is arranged at the end of the fixed tube 104, regulating holes S3 are opened on both sides of the bottom of the regulating tube 102, and the seepage pieces 106 are respectively arranged on the outside of the connecting hole S2 and the regulating hole S3.

[0036] L-shaped rods are fixed on both sides of the seepage pipe 101 to fix it and improve its installation convenience and stability. The regulating pipe 102 can rotate and move up and down in the seepage pipe 101. Its top is connected to an additional pipe to pass microorganisms, nutrient solution and carbon dioxide gas into the foundation. The temperature control pipe 103 is U-shaped, and its outside is connected to a ground source heat pump or air conditioning. It is used to control the temperature near the seepage pipe 101 to near zero degrees. The low temperature environment prevents premature calcification of the calcareous sand nearby, allowing the microorganisms to infiltrate to a farther distance.

[0037] There are multiple fixed pipes 104 and seepage holes S1, which are equidistantly distributed on both sides of the seepage pipe 101. The closure 105 is used to close the fixed pipe 104 in the initial state, so as to prevent excessive groundwater and other substances from entering the seepage pipe 101 during installation and affecting its subsequent operation. There are two groups of seepage parts 106, corresponding to two seepage modes. The number and position of the first group correspond to the fixed pipe 104, and microbial infiltration can be performed at multiple positions simultaneously, which is more uniform and efficient. The second group is set at the bottom of the adjusting pipe 102. The staff can pull the adjusting pipe 102 up and down so that the seepage parts 106 at the bottom can be connected with the fixed pipes 104 at different heights, so that they can be supplemented at certain locations with uneven microbial penetration or incomplete calcification, further improving the efficiency and stability of calcification.

[0038] The mounting frame 201 is fixed to the inner wall of the seepage tube 101, the regulating tube 102 is located on the inner side of the mounting frame 201, the limiting strips 202 are fixed on both sides of the regulating tube 102, the trigger block 203 is fixed on one side of the limiting strips 202, and the limiting member 204 is arranged in the mounting frame 201, which cooperates with the trigger block 203.

[0039] The mounting frame 201 is used to limit the adjusting tube 102 to prevent it from shifting when rotating and moving up and down. Through holes are provided on both sides of the mounting frame 201. The limiting strips 202 are located in the through holes. The adjusting tube 102 can be limited by the limiting strips 202. In the position shown in the figure, multiple seepage parts 106 are connected to the fixed tube 104. At this time, the limiting strips 202 have a limiting effect, so that the two can be accurately and conveniently fitted. A magnet is provided on the limiting strip 202, and a magnet is also provided on the mounting frame 201 accordingly. In this state, the attraction of the magnet can make it more stable to avoid shaking during the seepage process. This part is not shown in the figure.

[0040] The number and spacing of the trigger blocks 203 are the same as those of the fixed tubes 104 , so that the trigger blocks 203 and the limit members 204 cooperate to adjust the position of the regulating tube 102 , so that the seepage member 106 at the bottom can be more accurately connected to each fixed tube 104 .

[0041] The receiving plates 205 are fixed to the tops of both sides of the adjusting tube 102 and are located at the top of the mounting frame 201 . The limiting blocks 206 are fixed to both sides of the adjusting tube 102 and are located at the bottom of the mounting frame 201 .

[0042] In the state shown in the figure, the receiving plate 205 and the limiting block 206 jointly support and limit the adjusting tube 102, making it more stable and more convenient to rotate.

[0043] Example 2

[0044] Reference Figures 1 to 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0045] Specifically, the closure member 105 includes a mounting block 105a, a rotating shaft 105b and a closing plate 105c. The mounting block 105a is fixed to the inner wall of the seepage tube 101. The rotating shaft 105b is rotatably connected to one side of the mounting block 105a. The closing plate 105c is fixed to the end of the rotating shaft 105b and cooperates with the fixed tube 104.

[0046] The part of the rotating shaft 105b located inside the mounting block 105a is provided with a torsion spring, which applies a reset force to the rotating shaft 105b and the closing plate 105c. This part is not shown in the figure. In the initial state, that is, when the torsion spring is in a relaxed state, the closing plate 105c is located in a position to close the fixed tube 104, so that when the seepage piece 106 is separated from the fixed tube 104, the closing plate 105c can close the fixed tube 104 synchronously and timely.

[0047] The fixed block 105d is fixed to one side of the mounting block 105a, the limiting magnet 105e is located below the fixed block 105d, the guide rod 105f is fixed to the top of the limiting magnet 105e, and its top end extends to above the fixed block 105d, the first spring 105g is fixed to the top of the fixed block 105d and is located on the surface of the guide rod 105f, the limiting plate 105h is fixed on the rotating shaft 105b, and a limiting groove P is provided on the top of the limiting magnet 105e to cooperate with the limiting magnet 105e.

[0048] The limiting groove P is arc-shaped, and the bottom of the limiting magnet 105e is also arc-shaped. The inner wall of the limiting groove P is also provided with a magnet, which attracts the limiting magnet 105e. When the initial fixed tube 104 is closed, the limiting plate 105h is located below the limiting magnet 105e, and the limiting effect of the limiting magnet 105e and the limiting plate 105h prevents the closing plate 105c from rotating easily. Only when the staff manually rotates the adjusting tube 102 and the force of the seepage member 106 can the closing plate 105c be opened. The guide rod 105f is used to limit the limiting magnet 105e. When the seepage member 106 drives the closing plate 105c and the rotating shaft 105b to rotate, the limiting magnet 105e will be pushed upward by the limiting plate 105h and disengaged from the limiting groove P. At this time, the limiting magnet 105e is guided and limited by the guide rod 105f to prevent it from shifting during the up and down movement. Moreover, since the bottom of the limiting magnet 105e is arc-shaped, when the limiting plate 105h is reset, the limiting magnet 105e will be lifted up first, and then the limiting magnet 105e will be pushed into the limiting groove P by the thrust of the first spring 105g for fixation.

[0049] The connecting pipe 106a is fixed to the outside of the connecting hole S2 and the adjusting hole S3, the fixing plate 106b is fixed to the adjusting pipe 102, the connecting shaft 106c is rotatably connected to one side of the fixing plate 106b, and the sealing plate 106d is fixed to the end of the connecting shaft 106c.

[0050] In the initial state, the sealing plate 106d closes the connecting tube 106a, thereby preventing water and other substances from entering the seepage tube 101 from outside and entering the regulating tube 102. The part of the connecting shaft 106c located in the fixed plate 106b is also provided with a torsion spring, which applies a reset force to the sealing plate 106d and the connecting shaft 106c. When the regulating tube 102 is rotated until the connecting tube 106a is connected with the fixed tube 104, the two tubes will respectively push the sealing plate 106d and the closing plate 105c to the open position, thereby connecting the connecting tube 106a with the fixed tube 104.

[0051] The seepage member 106 further includes a stopper 106e and a protrusion 106f. The stopper 106e is fixed on the fixing plate 106b, and the protrusion 106f is fixed on the surface of the connecting shaft 106c and cooperates with the stopper 106e.

[0052] The sealing plate 106d can only rotate in one direction. In the initial state, the protrusion 106f contacts the stopper 106e. In this state, the sealing plate 106d closes the connecting pipe 106a, making it easier to reset.

[0053] The sealing ring 106g is disposed in the connecting pipe 106a, and a sliding groove M is opened on the inner side thereof. The guide block 106h is fixed to the inner wall of the connecting pipe 106a and slides in the sliding groove M. The first elastic piece 106i is fixed in the sliding groove M.

[0054] The sealing ring 106g can be telescopically moved. Since the connecting tube 106a and the fixed tube 104 cannot be completely fitted together when rotating, when the two are connected, a sealing operation can be performed through the sealing ring 106g to prevent leakage of microorganisms and nutrient solution before entering the groundwater. At least four guide blocks 106h are provided, which are symmetrically distributed on the inner side of the sealing ring 106g to limit and guide the sealing ring 106g to prevent it from deviating when moving. The first elastic piece 106i applies a force to the sealing ring 106g to move outward, and its farthest extended position is in contact with the fixed tube 104. Since one end of the first elastic piece 106i is fixed to the sealing ring 106g, the sealing ring 106g will not be separated from the connecting tube 106a. When the sealing plate 106d rotates to close the connecting tube 106a, the sealing ring 106g will be pushed into the connecting tube 106a.

[0055] An installation slot Y is provided in the installation frame 201, and the slider 204a slides in the installation slot Y. An inclined slot N is provided on one side thereof to cooperate with the trigger block 203. The connecting block 204b is fixed in the installation slot Y, and both ends of the second spring 204c are respectively fixed to the slider 204a and the connecting block 204b.

[0056] One side of the slider 204a is chamfered, and the other side of the limit strip 202 is also chamfered. The second spring 204c applies a force to the slider 204a away from the inside of the installation slot Y. When the adjusting tube 102 is rotated, there are two states. In the first state, the trigger block 203 corresponds to the position of the inclined slot N. At this time, the connecting pipe 106a at the bottom will be connected with the fixed tube 104 during rotation. If the adjusting tube 102 is continuously rotated, the trigger block 203 will move in the inclined slot N and push the slider 204a to move into the installation slot Y. At this time, the limit strip 202 will move during continuous rotation. The connecting tube 106a moves to the other side of the slider 204a until the connecting tube 106a is completely connected with the fixed tube 104. When rotating in the opposite direction, the limit bar 202 will directly push the slider 204a away. In the second state, the trigger block 203 does not correspond to the position of the inclined slot N, that is, the connecting tube 106a will not be connected with the fixed tube 104 when rotating. At this time, the limit bar 202 will be blocked by the slider 204a and cannot continue to move, thereby avoiding the connecting tube 106a and the fixed tube 104 from pushing away their respective closed plates when the position is offset, causing leakage.

[0057] An arc groove V1 is formed inside the mounting frame 201 , and a connecting groove V2 is formed on one side of the inner wall of the arc groove V1 . The movable bar 204 d slides in the connecting groove V2 , and one end thereof extends into the arc groove V1 . The second elastic piece 204 e is fixed in the connecting groove V2 .

[0058] There are two movable bars 204d. When the trigger block 203 and the limit bar 202 move to the other side of the slider 204a, the trigger block 203 is limited by the two movable bars 204d to prevent it from moving up and down. The connecting groove V2 has two parts, one part is for the movable bar 204d to move, and this part is symmetrically distributed at its top and bottom, and the other part is located between the two movable bars 204d. When the connecting pipe 106a is fully connected with the fixed pipe 104, the trigger block 203 is correspondingly inserted into this part of the groove, so that the position can be fixed and limited, so that the connection between the connecting pipe 106a and the fixed pipe 104 is more accurate and convenient. At the same time, magnets are provided in the groove and on the trigger block 203 for adsorption to improve its stability during use. This part is not shown in the figure.

[0059] Example 3

[0060] Reference Figures 1 to 11 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0061] Specifically, the following construction methods are also included:

[0062] The seepage pipe 101 and the regulating pipe 102 are installed at the designated position and fixed by an L-shaped rod to make them more stable. In the plane layout, multiple seepage pipes 101 and regulating pipes 102 are arranged in a plum blossom shape, and the density of the arrangement upstream of the groundwater is higher, so that microorganisms and nutrient solution can flow downstream through the seepage of the groundwater to perform calcification reaction;

[0063] Manually rotate the adjusting tube 102 so that the fixed tube 104 is connected to the seepage member 106 on the connecting hole S2;

[0064] The connecting pipe 106a is connected to the fixed pipe 104, and the nutrient solution, microorganisms, carbon dioxide and fine fibers are introduced into the groundwater, and seep into the groundwater to a designated position to perform a calcification operation and fill the gaps in the calcareous sand, thereby achieving the purpose of strengthening the foundation. The nutrient solution and microorganisms are wrapped by tiny soluble capsules, so that they can be carried by the groundwater to a farther place before contacting with the calcareous sand to react. The manufacturing process of the capsule is a prior art and will not be described in detail here.

[0065] When it is necessary to adjust the calcification degree at different heights, the adjusting tube 102 is rotated so that the fixed tube 104 is connected with the seepage member 106 on the adjusting hole S3, and the seepage position is adjusted by manually pulling the height of the adjusting tube 102;

[0066] After calcification is complete, the device is removed.
