[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] 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 phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth. Example 1

[0029] Reference Figures 1-6 This is the first embodiment of the present invention, which provides a basement anti-cracking retaining wall structure. This device includes... The supporting mechanism 100 includes a detachable outer support plate 110, a snap-fit ​​top plate 120 that is movably snapped onto the top of the outer support plate 110, a hanging assembly 130 that is disposed on the top of the snap-fit ​​top plate 120, and a mold assembly 140 located on the outside of the outer support plate 110. The core load-bearing mechanism 200 includes a limiting groove plate 210, an anchor seat 220 fixedly installed on the outside of the limiting groove plate 210, an anchor rod body 230 movably inserted into the inner cavity of the anchor seat 220, and a protective sleeve 240 sleeved on the outside of the anchor rod body 230.

[0030] The modular assembly and efficient construction are achieved by setting up a detachable load-bearing mechanism 100 and a core load-bearing mechanism 200. The outer support plate 110 and the snap-fit ​​top plate 120 cooperate to form a detachable support frame, which facilitates rapid on-site installation. The mold assembly 140 can be flexibly adjusted according to actual needs to improve the pouring quality. The limiting groove plate 210 and the anchor seat 220 are combined with the anchor rod body 230 to enhance the tensile performance of the overall structure. At the same time, the sheath 240 protects the anchor rod from corrosion and extends its service life. This structure effectively disperses soil pressure and reduces the risk of cracking, making it suitable for basement construction under complex geological conditions.

[0031] Specifically, the core load-bearing mechanism 200 also includes a lateral tie rod 250 fixedly installed on the outside of the anchor seat 220, and a steel rope 260 fixedly installed on one end of the anchor body 230. There are three lateral tie rods 250, which are evenly distributed on the outside of the anchor seat 220.

[0032] The addition of lateral tie rods 250 effectively resists lateral earth pressure and improves the overall stability of the retaining wall. The steel rope 260 is connected to the anchor body 230 to form a tensioning system, which further enhances the structure's resistance to deformation and can adapt to the construction needs of basements of different depths. This ensures that the retaining wall maintains its structural integrity during long-term use. The use of three evenly distributed tie rods makes the anchoring force distribution more balanced and significantly improves the bearing capacity of the anchor seat 220. This symmetrical layout can effectively offset uneven earth pressure and prevent wall cracking caused by local stress concentration. It is especially suitable for retaining wall construction under conditions of high groundwater level or soft soil foundation.

[0033] Furthermore, the bearing mechanism 100 also includes a limiting seat 150 fixedly installed on the top of the snap-fit ​​top plate 120, an inner support plate 160 movably snapped with the outer support plate 110 and embedded in the wall, a pressure rod 170 movably placed at the bend of the outer support plate 110, a positioning component 180 provided on the outside of the outer support plate 110 and used in conjunction with the hanging component 130, and a protective film 190 laid on the outside of the outer support plate 110. The limiting groove plate 210 is fixedly connected to the outside of the inner support plate 160, and the steel rope 260 is movably snapped in the inner cavity of the limiting seat 150, with one end passing through the anchor seat 220 and connected to the anchor rod body 230.

[0034] The embedded connection between the limiting seat 150 and the inner support plate 160 ensures a tight fit between the support system and the wall. The pressure bar 170 can flexibly adjust the stress state of the outer support plate 110 to adapt to different pouring conditions. The positioning component 180 and the protective membrane 190 work together to ensure the positioning accuracy of the template 141 and prevent concrete from contaminating the outer support plate 110, significantly improving construction efficiency and finished product quality. The fixed connection between the limiting groove plate 210 and the inner support plate 160 further strengthens the overall integrity of the structure. By inserting the steel rope 260 into the limiting seat 150 and passing through the anchor 220, a two-way tensioning system is formed. This design allows the prestress of the anchor body 230 to be dynamically adjusted, which can adapt to stress changes caused by soil creep and absorb part of the impact load through the elastic deformation of the steel rope 260, greatly improving the seismic performance and long-term durability of the retaining wall.

[0035] In use, the outer support plate 110 and the inner support plate 160 are first assembled into a template frame. The snap-fit ​​top plate 120 is installed and the hanging component 130 and the protective membrane 190 are fixed. Then, the mold component 140 is installed and adjusted to the design thickness. At the same time, the core load-bearing mechanism 200 is assembled. The anchor rod 230 is inserted into the anchor seat 220 and reinforced by the lateral tie rod 250. The steel rope 260 passes through the limiting seat 150 to form a tensioning system. Then, concrete is poured in layers and the stress on the support plate is adjusted by the pressure rod 170. After the curing period, the mold component 140 and the load-bearing mechanism 100 are removed in sequence, and finally a retaining wall structure with excellent crack resistance and convenient construction is formed.

[0036] In summary, the detachable outer support plate 110 and the snap-fit ​​top plate 120 in the load-bearing mechanism 100 form a quick-assembly support frame, which, together with the adjustable mold assembly 140, ensures the quality of pouring. The core load-bearing mechanism 200 forms a spatial force-bearing system through the limiting groove plate 210, the anchor seat 220, and three evenly distributed lateral tie rods 250. Combined with the anchor body 230 with the sheath tube 240 and the steel rope 260, a bidirectional tensioning system is formed, which significantly improves the tensile and deformation resistance. The embedded connection between the inner support plate 160 and the limiting groove plate 210 enhances the overall integrity. The pressure rod 170 and the positioning assembly 180 enable adjustable force. The protective membrane 190 ensures the cleanliness of construction. This multi-mechanism collaborative design not only achieves rapid assembly and construction but also effectively prevents cracking through stress dispersion and dynamic adjustment mechanisms. It is particularly suitable for high-standard basement projects under complex geological conditions. Example 2

[0037] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it provides an optimized scheme for the coordinated action of the hanging component 130 and the positioning component 180, which further improves the adaptability and construction convenience of the template system.

[0038] Furthermore, the hanging assembly 130 includes a vertical plate 131 fixedly installed on the top of the snap-fit ​​top plate 120, a fixing plate 132 fixedly installed on the outside of the vertical plate 131, and a bearing 133 fixedly installed on the outside of the fixing plate 132. The hanging assembly 130 also includes an elastic pull rod 134 hinged to the outside of the bearing 133, a rotating shaft 135 hinged to the inner cavity of the elastic pull rod 134, and a first hook 136 fixedly connected to the outside of the rotating shaft 135. The vertical plate 131 and the fixed plate 132 form a rigid support frame, and the bearing 133 provides an installation base for the subsequent elastic connection components. This structure achieves rapid assembly through modular design. Its vertical load transfer path is clear, which can effectively share the weight of the formwork system and reduce the risk of structural deformation during construction. The elastic tie rod 134 achieves multi-directional rotation through the rotating shaft 135 and forms an adaptive suspension system with the first hook 136. This design allows the formwork 141 to undergo slight displacement during concrete pouring, avoids stress concentration caused by rigid constraints, and ensures that the protective membrane 190 is always in a taut state, which significantly improves the surface forming quality of the concrete.

[0039] Furthermore, the positioning component 180 includes a snap-fit ​​plate 181 that is movably snapped onto the outside of the outer support plate 110, a threaded seat 182 that is fixedly installed on the outside of the snap-fit ​​plate 181, and a second hook 183 that is threaded into the inner cavity of the threaded seat 182. The outer side of the protective film body 190 is provided with a hole for hanging at the first hook 136 and the second hook 183.

[0040] The snap-fit ​​plate 181 and the threaded seat 182 form an adjustable connection node. The tension of the protective membrane 190 can be precisely controlled by rotating the second hook 183. This complements the elastic suspension system of the hanging component 130, ensuring the reliability of the temporary fixation of the protective membrane 190 during construction and facilitating the removal of the protective membrane 190 later. This demonstrates the technological advantages of the prefabricated structure. The matching design of the holes and hooks of the protective membrane 190 further simplifies the construction process.

[0041] In use, the outer support plate 110 and the inner support plate 160 are first assembled to form a template frame. The top is fixed by snapping on the top plate 120. Then, the hanging component 130 is installed on the snapping on the top plate 120, and the protective membrane 190 is suspended at the first hook 136 of the elastic tie rod 134. Next, the tension of the protective membrane 190 is adjusted by the second hook 183 of the positioning component 180. The mold component 140 is installed on the outside of the template 141 frame, and the anchor rod 230 and the lateral tie rod 250 of the core load-bearing mechanism 200 are fixed. After the concrete is poured, the mold component 140, the positioning component 180 and the hanging component 130 are removed in sequence after the concrete reaches its strength. Finally, a retaining wall structure with multiple anti-cracking functions is formed. The whole process realizes the organic combination of prefabricated construction and anti-cracking function.

[0042] In summary, the coordinated design of the hanging component 130 and the positioning component 180 forms a dual fixing system for the protective membrane 190. The hanging component 130 provides flexible fixing through the elastic tie rod 134 and the first hook 136, allowing the protective membrane 190 to undergo moderate deformation with the concrete pouring during construction, thus preventing the membrane from tearing. At the same time, the positioning component 180 achieves precise tension control through the adjustable threaded seat 182 and the second hook 183, ensuring that the protective membrane 190 always fits flat against the surface of the template 141. This combination of rigidity and flexibility eliminates the stress concentration problem caused by traditional fixing methods and effectively prevents concrete slurry leakage. It ensures the stability of the protective membrane 190 during construction and facilitates non-destructive removal later, significantly improving the appearance quality of the concrete and construction efficiency. Example 3

[0043] Reference Figure 1 and Figure 5 This is the third embodiment of the present invention, which differs from the second embodiment in that it provides an adjustable formwork system through the mold assembly 140, which significantly improves the quality of concrete pouring and construction adaptability.

[0044] Furthermore, the mold assembly 140 includes a template 141 movably mounted between the outer support plate 110 and the inner support plate 160, a side plate 142 movably mounted on the outside of the template 141, a grouting hole 143 opened on the top of the template 141, and an air vent 144 opened on the outside of the template 141.

[0045] The template 141 and the side plate 142 are connected by a movable snap-fit ​​method, which makes it easy to adjust flexibly according to the wall thickness. The optimized arrangement of the grouting holes 143 ensures that the concrete is filled densely. The venting slot 144 effectively discharges the air trapped during pouring. The synergistic effect of the two can eliminate quality defects such as honeycomb and pitting, so that the formed retaining wall has both structural strength and appearance quality.

[0046] In use, first adjust the snap-fit ​​position of the side clamping plate 142 and the template 141 according to the designed wall thickness to complete the rapid assembly of the mold assembly 140. Then, pour concrete in three layers through the grouting hole 143 and use an immersion vibrator to fully vibrate it. During the vibration process, use the venting port 144 to timely remove the air inside the concrete to ensure the compactness of the pouring. After the concrete has initially set, remove the side clamping plate 142 for reuse, and keep the template 141 until the end of the curing period. Finally, complete the disassembly of the entire mold assembly 140 to form a retaining wall with excellent appearance quality and structural performance.

[0047] In summary, the movable snap-fit ​​design of the template 141 and the side clamping plate 142 allows for flexible adjustment of the wall thickness to meet different engineering needs. The reasonably set grouting holes 143 ensure uniform filling during concrete pouring, improving structural density. The carefully designed venting slots 144 effectively remove air bubbles generated during pouring, avoiding quality defects. The synergistic effect of the entire mold assembly 140 not only ensures the structural strength and appearance quality of the retaining wall but also improves the adaptability and efficiency of construction. Example 4

[0048] Reference Figures 1-6 This is the fourth embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a construction method, including a basement anti-cracking retaining wall structure, the method comprising the following steps: S1: Measure and lay out the lines according to the design drawings to determine the location of the retaining wall, and level and compact the foundation. Install the outer support plate 110 and the inner support plate 160, and fix them by snapping on the top plate 120 to form a template frame structure. S2: Install the mold assembly 140, adjust the snap-fit ​​position of the template 141 and the side plate 142 according to the wall thickness requirements, install the hanging assembly 130 and fix the protective film 190 to the first hook 136, and adjust the tension of the protective film 190 using the second hook 183 of the positioning assembly 180. S3: Pour concrete in layers through grouting holes 143, and expel air through venting slots 144 during vibration. After pouring, cover and cure in time to keep the concrete surface moist. The curing time shall not be less than 7 days. S4: After the concrete reaches the design strength, remove the side plate 142, formwork 141 and other components in sequence, check the appearance quality and structural performance of the retaining wall, ensure that there are no defects such as cracks and honeycomb, and complete the acceptance.

[0049] In summary, the construction method provided in this embodiment achieves efficient and high-quality construction of basement retaining walls, ensuring the crack resistance of the structure and improving construction efficiency, and is applicable to various basement projects.
