[0002] During the construction of the emergency water plant, the construction of retaining walls is a crucial step in ensuring construction safety and foundation stability. Existing retaining wall construction methods typically employ cast-in-place concrete structures, requiring multiple steps such as formwork erection, rebar tying, concrete pouring, and curing. This process is complex and time-consuming. Furthermore, traditional retaining wall construction relies heavily on manual labor, is significantly affected by site conditions and weather factors, resulting in low construction efficiency, and is prone to quality problems during concrete pouring, such as formwork deformation leading to wall displacement and concrete shrinkage cracking, which hinders quality control.

[0003] Meanwhile, the construction of the emergency water plant was time-sensitive, requiring the rapid erection of retaining walls to ensure the subsequent installation of equipment and pipelines. However, traditional construction methods were insufficient to meet the demands of rapid construction, and setting up formwork and tying reinforcing bars in narrow construction areas presented challenges, affecting both the convenience and safety of the construction process.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Example

[0031] The following is for reference Figures 1-6As shown in the illustration, and further explained with reference to a specific embodiment, this embodiment provides a retaining wall structure, including a base 1. The base 1 is pre-installed on a horizontal ground to ensure the stability of the overall structure. A pair of insertion rods 11 are fixedly installed at the bottom of the base 1, allowing adjustment of the number and spacing of the insertion rods 11 according to construction needs to adapt to different soil conditions and stress requirements. A guide portion 12 is provided at the top of the base 1. The guide portion 12 has an isosceles trapezoidal cross-section, with its top being the short side, to ensure that the retaining wall 2 can be stably slidably positioned along the guide portion 12 during installation.

[0032] A pair of limit blocks 121 are cast integrally onto the guide section 12 to increase structural strength and reliability. The limit blocks 121 are dovetail-shaped to improve the stability of the sliding engagement. In other embodiments, the limit blocks 121 can be designed as T-shaped or other suitable shapes according to construction requirements to adapt to different connection requirements of the retaining wall 2.

[0033] A limiting groove 21 is provided at the bottom of the retaining wall 2. The length of the limiting groove 21 is greater than the length of the limiting block 121 to ensure that the retaining wall 2 can slide smoothly into the limiting block 121 for positioning. One end of the limiting groove 21 is provided with an opening groove 211 into which the limiting block 121 is moved, so that the retaining wall 2 can be smoothly engaged with the base 1, thereby achieving convenient installation.

[0034] To further enhance the stability of the retaining wall, the reinforcing rod 3 is inserted obliquely through the retaining wall 2, the limiting block 121, and the base 1. The bottom of the reinforcing rod 3 protrudes from the base 1 and inserts into the ground to provide additional anchoring and improve resistance to lateral thrust. The reinforcing rod 3 has a hollow structure with a grout inlet 31 at the top and multiple grout outlet holes 32 at the bottom, facilitating the diffusion of grout underground after injection and improving the reinforcement effect.

[0035] In other embodiments, the angle, length, or number of reinforcing rods 3 can be adjusted according to project needs to adapt to different construction environments and stress conditions. Furthermore, the base 1 can be thickened according to geological conditions, or anti-slip textures can be added to the bottom of the base 1 to improve overall anti-slip capability. The retaining wall 2 can be made of reinforced concrete, prestressed concrete, or other high-strength materials to further enhance durability and load-bearing capacity.

[0036] Reference Figure 3 and Figure 6As shown, a connecting groove 212 is provided at the top of the limiting groove 21. The cross-section of the connecting groove 212 is semi-circular to facilitate casting and molding. The connecting groove 212 allows the concrete grout to be evenly distributed inside the limiting groove 21, thereby improving the bond strength between the retaining wall 2 and the base 1. A connecting hole 33 is provided at the position where the reinforcing rod 3 passes through the connecting groove 212. Grout can enter the interior of the limiting groove 21 through the connecting hole 33, so that the retaining wall 2 can form an integral structure after installation by curing the grout, further improving its stability and resistance to lateral displacement. In addition, in other embodiments, the shape of the connecting groove 212 can be adjusted according to construction needs. For example, it can be set as a grid distribution to improve the uniformity of grout flow and optimize the bonding effect.

[0037] Reference Figure 3 and Figure 5 As shown, the guide section 12 and the sliding surface of the retaining wall 2 are provided with crisscrossing overflow grooves 122. This structure helps the grout to be evenly distributed during the sliding and clamping process and provides additional shear resistance, preventing the retaining wall 2 from loosening or shifting due to insufficient local bonding. The crisscrossing arrangement of the overflow grooves 122 can effectively increase the overall bonding area, enhance the bonding force between the retaining wall 2 and the base 1, and at the same time reduce grout accumulation and improve construction quality.

[0038] Both sides of the base 1 are integrally cast with retaining edges 13 along their length. The retaining edges 13 are hollow and cover the outlet of the overflow grout trough 122. This design allows excess grout to be guided into the retaining edges 13 during grout overflow, thus preventing grout from overflowing and affecting the construction environment, and improving the appearance quality of the retaining wall 2. The top of the retaining edges 13 has multiple through holes 131 that communicate with its interior, allowing excess grout to drain through the through holes 131, preventing grout accumulation that could lead to excessive internal pressure and affect the bonding effect.

[0039] Furthermore, the top wall of the retaining flange 13 is inclined, and the through hole 131 is formed on this inclined surface, which provides a certain degree of guidance for the grout discharge direction, ensuring smooth grout discharge and preventing residual deposits from forming inside the retaining flange 13, thereby improving the overall durability of the structure and the construction quality. In other embodiments, the structure of the retaining flange 13 can be further optimized, for example, by setting up multi-stage grout discharge channels or adding removable cleaning holes to facilitate necessary adjustments and maintenance during construction.

[0040] Reference Figure 2 and Figure 3As shown, the reinforcing rod 3 is inserted into the retaining wall 2 at a point along the length of the retaining wall 2's side wall, which has a vertically formed pouring groove 22. The pouring groove 22 not only connects to the grout inlet at the top of the reinforcing rod 3 but also forms a grout filling channel between adjacent retaining walls 2, thereby enhancing the overall connection strength between adjacent retaining walls 2. Through the pouring groove 22, the connection between adjacent retaining walls 2 is tighter, effectively improving the overall impact resistance and lateral thrust resistance of the retaining walls 2. Simultaneously, the size of the pouring groove 22 is rationally designed to ensure that the reinforcing rod 3 can smoothly pass through the retaining wall 2 in an oblique insertion manner and form a stable connection with the base 1, improving construction convenience.

[0041] Reference Figure 3 and Figure 4 As shown, a positioning post 34 is provided on the side of the reinforcing rod 3 near its grout inlet, and a positioning groove 221 that mates with the positioning post 34 is provided in the pouring groove 22. The presence of the positioning post 34 and the positioning groove 221 ensures that the reinforcing rod 3 is always in the preset position during installation, thereby avoiding displacement during construction. At the same time, this structure can also effectively guide the grout flowing out of the connecting hole 33, allowing the grout to enter the connecting groove 212 more accurately and evenly fill the entire space of the limiting groove 21, improving the permeability and bonding effect of the grout, thereby further enhancing the overall strength between the retaining wall 2 and the base 1. In addition, in other embodiments, the positioning post 34 and the positioning groove 221 can adopt different mating structures, such as square plug-in or snap-fit ​​mating, to adapt to the needs of different construction environments.

[0042] Furthermore, multiple insert plates 14 are installed at intervals on the bottom wall of the base 1. The presence of the insert plates 14 enhances the anchoring effect between the base 1 and the ground, making the retaining wall more stable overall. The number and spacing of the insert plates 14 can be adjusted according to construction needs to adapt to construction requirements under different geological conditions. In soft soil environments, the number of insert plates 14 can be appropriately increased to improve the pull-out resistance of the base 1; in harder foundation environments, the number of insert plates 14 can be appropriately reduced to optimize construction efficiency. In addition, the shape of the insert plates 14 can be designed as wedge-shaped, corrugated, or toothed according to construction needs to increase the friction between the insert plates 14 and the ground, thereby enhancing the stability of the overall structure.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
