[0069] Based on the construction of the above model as a guide, the supporting wall retaining in this application is composed of multiple wall units, and adjacent wall units are elastically connected. This structural design can effectively disperse stress and avoid stress concentration in a certain place causing wall slippage; adjusting cables are respectively set on the sides of the columns close to the bottom beam, and a transverse adjustment mechanism is set between adjacent columns for precise adjustment to ensure the verticality of the columns and the firmness of the connection between them, thereby improving the overall stability of the supporting structure and reducing the risk of wall slippage caused by the tilt of the columns; the deformation monitor, verticality monitor and soil quality monitor in the auxiliary mechanism are connected to the controller, which can monitor various parameters of the supporting structure in real time (such as the deformation of the adjusting cable, the verticality of the column, the soil condition, etc.).

The connection mechanism between wall units (such as the connection seat and the connection member between the bottom beams) can buffer the external force to a certain extent, so that the wall can remain relatively stable when subjected to lateral soil pressure, groundwater seepage force, etc., greatly enhancing the overall anti-slip ability. The grouting channel of the column and the multi-layer structure (first shear layer, second shear layer and guide layer) design enable grouting reinforcement and other operations to be performed as needed under different geological conditions, thereby enhancing the stability of the column in various complex geologies and adapting to different geological conditions such as soil particle gaps, looseness and hydrophobicity. The setting of the elastic connection parts of adjacent wall units (composed of inner shell, outer shell, connection plate and buffer medium, etc.) enables the adjacent wall units to freely expand and contract and buffer within a certain range, and can adapt to the foundation settlement, external force changes, etc., to ensure that the support structure always maintains good performance in different construction environments and geological changes. The wall units are filled with concrete embedded with transverse reinforcing fibers and vertical reinforcing fibers, which enhances the connection strength and overall rigidity between the wall units, and works together with other structural components to form a stable support system, effectively resisting various external forces, and ensuring the safety of the project and the stability of the surrounding environment.

[0071] This application is designed and optimized from multiple aspects, with various components working together, from the bottom beam and column connections of the foundation to the elastic connections and concrete filling between the wall units, to the feedback control of the monitoring and adjustment system, which comprehensively improves the overall stability of the anti-slip support retaining wall.

[0123] When the column 10 is absolutely vertical, the strains of the adjusting cables 17 located around the same column 10 are the same, so the skew direction of the column 10 can be obtained by comparing the deformation monitors on the adjusting cables 7 arranged around the same column 10, so as to adjust the verticality of the column 10 by tightening or loosening the corresponding adjusting cables 7 according to the feedback data;

[0124] Afterwards, the lateral displacement between the top and bottom of adjacent columns is adjusted to further improve the verticality of the installation of the columns 10 .

[0129] Both ends of the rod adjusting mechanism 12 are respectively connected to the connection between the column 10 and the end adjusting mechanism 11 .

[0130] Furthermore, the end adjustment mechanism 11 is a telescopic member.

[0131] It should be noted that, in the present application, the end adjustment mechanism 11 is a telescopic rod.

[0132] Furthermore, the rod adjustment mechanism 12 is a scissor-fork structure as a whole;

[0133] Both ends of the rod adjusting mechanism 12 are detachably connected to two adjacent columns 10 .

[0134] Furthermore, a connecting mechanism is provided between two adjacent bottom beams 1;

[0135] The connecting mechanism comprises a connecting seat 2 and a connecting assembly;

[0136] The connecting seat 2 is located between opposite ends of two adjacent bottom beams 1 and is movably connected to opposite ends of the two adjacent bottom beams 1. The connecting seat 2 is an isosceles triangle as a whole, and a mounting plate 5 is provided at the bottom of the connecting seat 2.

[0137] The mounting plate 5 is disposed at a gap at the bottom of the connecting seat 2, and the mounting plate 5 is elastically connected to the connecting seat 2;

[0138] The connecting assembly includes a limiting groove and a connecting member 6;

[0139] The limiting grooves include a first limiting groove 7 provided at the bottom of the opposite ends of two adjacent bottom beams 1, and two second limiting grooves 3 located at the bottom of the connecting seat 2;

[0140] The connecting member 6 is in an overall V-shaped structure with an opening upward, and is located between the mounting plate 5 and the connecting seat 2. Two connecting members 6 are arranged opposite to each other, and the two connecting members 6 are installed on the top of the mounting plate 5. The shapes of the two ends of the connecting member 6 match the adjacent first limiting groove 7 and the second limiting groove 3 respectively, and one end of the connecting member 6 is located in the second limiting groove 3, and the other end of the connecting member 6 is located in the adjacent first limiting groove 7;

[0141] The cross-sections of the first limiting groove 7 and the second limiting groove 3 are arc-shaped, and the first limiting groove 7 and the second limiting groove 3 are respectively provided with gaps between the two ends of the connecting member 6;

[0142] The end surfaces of the opposite ends of two adjacent bottom beams 1 are matched with the inclined surfaces of the connected connection seats 2 respectively.

[0143] It should be noted that, in the present application, two bottom beams located in two adjacent wall units are movably connected via a connecting assembly:

[0144] To avoid mutual influence between wall units, leave space for the movement of wall units, and provide a buffer between bottom beams to avoid slippage. The specific implementation method is:

[0145] The two sides of the connecting seat 2 (i.e., the two side surfaces of the isosceles triangle) are respectively slidably connected to the end surfaces of the opposite ends of the two adjacent bottom beams 1 on the two adjacent wall units.

[0146] The connecting member 6 is in an upward V-shaped structure as a whole, and the two ends of the connecting member 6 (i.e., the first connecting end 4 and the second connecting end 8) are respectively located in the second limiting groove 3 and the first limiting groove 7 at the bottom of the connecting seat 2; the cross-sections of the second limiting groove 3 and the first limiting groove 7 and the ends of the connecting member 6 are in an arc shape. When a certain wall unit is subjected to a sudden change in the external force in the vertical direction, the end of the connecting member 6 correspondingly installed in the first limiting groove 7 at the bottom of the bottom beam 1 of the wall unit is pressed down, and the arc is deformed, so that the bottom beam 1 of the unit wall goes uphill or downhill along the connecting seat 2 accordingly, so as to alleviate the sudden change in the external force;

[0147] When a wall unit is subjected to a sudden change in external force in the vertical direction, the end of the connecting member 6 in the first limiting groove 7 at the bottom of the bottom beam 1 of the wall unit is subjected to a lateral force, and the arc is deformed left and right, so that the bottom beam 1 of the unit wall moves uphill or downhill along the connecting seat 2 to alleviate the sudden external force;

[0148] At the same time, the connection section of the connecting seat 2 and the two adjacent bottom beams 1 located on the two adjacent wall units forms a triangle, which can not only play a shock-absorbing role, but also achieve mutual entanglement among the three, thereby providing a relative stability.

[0149] The mounting plate 5 is connected to the bottom of the connecting seat 2 through an elastic column, and an elastic protective plate is arranged on the surrounding side of the mounting plate 5. One end of the elastic plate is sealed and connected to the bottom of two opposite bottom beams 1 of two adjacent wall units, and the other end of the elastic protective plate is connected to the mounting plate 7.

[0150] Furthermore, a grouting channel is provided at the center of the column 10 , and the grouting channel penetrates the column 10 along the extension direction of the column 10 .

[0151] Furthermore, the column 10 includes a first shear resistance layer 23, a second shear resistance layer 24 and a guide layer 25 arranged on one side from the inside to the outside;

[0152] The first shear resistance layer 23 is a tubular structure, and a plurality of first grouting holes are evenly arranged on the first shear resistance layer 23;

[0153] The second shear resistance layer 24 is connected to the outer side of the first shear resistance layer 23;

[0154] The guide layer 25 is connected to the outer side of the second shear resistance layer 24, a plurality of second grouting holes are evenly arranged on the guide layer 25, and a plurality of guide pipes 26 are arranged outside the guide layer 25;

[0155] The guide pipes are connected to the second grouting holes respectively.

[0156] Furthermore, elastic connecting parts are respectively provided between two opposite upright posts 10 of two adjacent wall units;

[0157] The elastic connection part includes an inner shell and an outer shell 18 arranged inside and outside;

[0158] The outer shell 18 is a hollow rectangular structure, and the outer shell 18 is an elastic shell. The two sides of the outer shell 18 are respectively connected to two opposite columns 10 of two adjacent wall units;

[0159] The inner shell is spaced apart from the outer shell 18, and the inner shell includes a fixing portion 13 and an elastic portion;

[0160] The elastic parts are respectively located on one side of the fixing part 13 facing two opposite upright posts 10 located in two adjacent wall units, and the elastic parts are respectively fixedly connected to two opposite sides of the outer shell 18;

[0161] Both sides of the fixing portion 13 are connected to the elastic portion to form a hollow cavity. The fixing portion 13 is provided with a first conducting hole 19 and a second conducting hole 20.

[0162] A connecting plate is provided in the hollow cavity;

[0163] The connecting plate is in a cross structure as a whole, one end of the connecting plate (the cross beam 22 of the connecting plate) is connected to two opposite columns 10 of two adjacent wall units, and the other end of the connecting plate (i.e. the vertical beam 21 of the connecting plate) is slidably connected to the fixing part 13 respectively, so as to separate the hollow cavity into two separate chambers;

[0164] The first conductive hole 19 and the second conductive hole 20 are located in two chambers respectively; the two chambers are filled with buffer media respectively.

[0165] It should be noted that:

[0166] In the present application, the outer shell 18 and the elastic portion of the inner shell are hard rubber;

[0167] The cross beam 22 of the connecting plate is two separate spring telescopic rods, the opposite ends of the two telescopic rods are respectively connected to the opposite sides of the vertical beam 21 of the connecting plate, and the opposite ends of the two telescopic rods pass through the inner shell and the outer shell 18 respectively to be connected to the two opposite columns 10 of the two adjacent wall units;

[0168] When the distance between two wall units changes, the side with greater force pushes the vertical beam 21 of the connecting plate to move left and right accordingly. At this time, the buffer medium in the chamber of the side with greater force flows into the chamber of the side with greater force. When the external force changes, the vertical beam 21 of the connecting plate is dragged back accordingly. At this time, the medium in the chamber of the side with greater force flows into the chamber of the side with greater force, thereby keeping the gap between the two adjacent wall units balanced at all times.

[0169] Furthermore, the wall units are filled with concrete, in which transverse reinforcing fibers and vertical reinforcing fibers are embedded.

[0170] It should be noted that: in the present application, when the column 10, the end adjustment mechanism 11 and the rod adjustment mechanism 12 are completely installed, the bottom beam 1, the two adjacent columns 10 located on the same bottom beam 1, the end adjustment mechanism 11 and the rod adjustment mechanism 12 located on the front and rear sides of the two adjacent columns 10 form a wall frame, and the vertical reinforcing fibers 14 are evenly installed along the extension direction of the wall frame, and the transverse reinforcing fibers 15 are evenly installed along the up and down direction of the wall frame, wherein the vertical reinforcing fibers 14 and the transverse reinforcing fibers 15 can be steel bars or other added fibers;

[0171] Then, based on the soil conditions collected before construction, concrete is used to pour the walls.
