[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "front", "rear", "middle", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "sheathed / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] Such as Figure 1As shown in the figure, an embodiment of the present utility model provides a retaining wall structure, including at least one set of tension wall components 1. The tension wall component 1 includes at least one tension member 100 and two relatively arranged walls 200. A filling space 203 is formed between the two walls 200 of the same tension wall component 1. All the tension members 100 in the tension wall component 1 connect the two walls 200 and are located in the filling space 203. Among them, the wall 200 is used to bear the horizontal soil pressure after filling in the filling space 203, thereby ensuring the filling stability before and after filling. Understandably, the tension member 100 is a component connecting the two walls 200. After filling in the filling space 203 between the two walls 200, the tension force provided by the tension member 100 connected between the two walls 200 can be used to reduce the eccentric stress of the wall 200. In one embodiment, as Figure 1 shown, the tension wall component 1 includes a plurality of tension members 100, and the plurality of tension members 100 are arranged in parallel at intervals. That is to say, in this embodiment, a plurality of tension members 100 need to be arranged in parallel at intervals between the two walls 200 of the same tension wall component 1 to ensure that the tension forces provided by all the tension members 100 can meet the structural strength requirements of the retaining wall structure.

[0030] Understandably, the retaining wall structure may include one or more sets of tension wall components 1, as Figure 1 shown in the figure, which is one set of tension wall components 1. However, in some embodiments, the retaining wall structure may also be composed of multiple sets of tension wall components 1, and the combination form of the multiple sets of tension wall components 1 can be set according to requirements; for example, the retaining wall structure may include multiple sets of tension wall components 1, and the filling spaces of the multiple sets of tension wall components 1 are connected. In this way, a longer retaining wall structure can be composed of multiple sets of tension wall components 1 with relatively short walls 200; multiple sets of tension wall components 1 can also be arranged in parallel, and the walls 200 of different tension wall components 1 are mutually attached, so that the thickness of the retaining wall structure can be increased; it is also possible to form multiple sets of tension wall components 1 into an annular structure, etc. The specific composition method is not limited here.

[0031] Furthermore, as Figure 1 and Figure 2 shown, the tension member 100 may include a tension cable 101 installed between the two walls 200 through an anchor head 300. The tension cable 101 includes but is not limited to steel bars or steel strands, etc. During construction, the wall 200 should be poured first, and through holes 205 should be reserved on the wall 200 for the tension cable 101 to pass through the through holes 205 to connect the anchor head 300, thereby completing the fixed connection between the tension cable 101 and the wall 200.

[0032] For the retaining wall structure of the present utility model, after filling the soil in the soil filling space 203 between the two walls 200 of the tensioned wall component 1, the tension member 100 connected between the two walls 200 can provide a tensile force, thereby reducing the eccentric stress of the wall 200. Thus, the anti-overturning ability and anti-sliding ability of the retaining wall structure can be enhanced, and the overall stability of the retaining wall structure can be improved. Moreover, for the retaining wall structure of the present utility model, even when the slope is relatively high and the horizontal soil pressure is relatively large, the foundation soil will not be damaged by lateral extrusion and can be applied to slopes above 12 m. At the same time, in the present utility model, there is no need to set up support piles, which reduces the material and construction costs and is more economical.

[0033] In one embodiment, the wall 200 includes a load-bearing member 201 and a vertical plate 202 installed on the load-bearing member 201, and all the tension members 100 in the same tensioned wall component 1 are connected between the vertical plates 202 of the two walls 200. Among them, the vertical plate 202 is used to bear the horizontal soil pressure after filling the soil in the soil filling space 203, thereby ensuring the soil filling stability before and after soil filling. The load-bearing member 201 is the part of the retaining wall structure in direct contact with the foundation soil at the bottom, which plays a role in fixing and supporting the entire structure. As Figure 1 shown, the load-bearing member 201 is directly placed on the foundation soil, which can increase the contact area between the vertical plate 202 of the retaining wall structure and the foundation soil, thereby increasing the base area and reducing the base stress. The height of the vertical plate 202 can be set according to specific requirements. For example, the height of the vertical plate 202 can be set to 2 m - 12 m.

[0034] In one embodiment, the wall 200 is an integrally cast structural member. That is, in this embodiment, the wall 200 is integrally cast. In this way, the vertical plate 202, the load-bearing member 201 and other structures of the wall 200 can be firmly connected, increasing the overall stiffness of the retaining wall structure. At the same time, it is also convenient for the installation of the tension member 100 with prestress (the prestress is the tensile force provided when the tension member 100 is pre-tensioned and installed between the two walls 200), and then bear the prestress.

[0035] In one embodiment, as Figure 1As shown, the bearing member 201 includes a wall toe plate 2011 connected to the vertical plate 202, and the wall toe plate 2011 is located on the side of the vertical plate 202 away from the earth-filling space 203. In this embodiment, the wall toe plate 2011 is a part of the bearing member 201 that is in direct contact with the foundation soil, which increases the base area of ​​contact between the wall 200 and the foundation soil, thereby reducing the base stress, and after the earth-filling space 203 between the two walls 200 is filled with soil, the wall toe plate 2011 is arranged on the side of the vertical plate 202 away from the earth-filling space 203, which reduces the possibility of the wall 200 overturning in the direction away from the other wall 200, and increases the overall anti-overturning stability of the retaining wall structure.

[0036] In one embodiment, if Figure 1 As shown, the bearing member 201 includes a wall heel plate 2012 connected to the vertical plate 202, and the wall heel plate 2012 is located in the fill space 203. It can be understood that the wall heel plate 2012 is a part of the bearing member 201 that is in direct contact with the foundation soil, which also increases the base area of ​​contact between the wall body 200 and the foundation soil, thereby reducing the base stress; and the wall heel plate 2012 connects the vertical plate 202 and the wall heel plate 2012, and can also play a role in fixing and supporting the entire retaining wall structure.

[0037] In one embodiment, if Figure 1 As shown, the wall heel plate 2012 and the wall toe plate 2011 are located on the same plane. In this embodiment, the vertical plate 202, the wall heel plate 2012 and the wall toe plate 2011 can be cast and formed as one piece, thereby improving the structural strength of the wall body 200. Among them, the wall heel plate 2012 and the wall toe plate 2011 of the same wall body 200 are located on the same plane, but the wall toe plate 2011 and the wall heel plate 2012 are respectively arranged on opposite sides of the vertical plate 202, and the wall toe plate 2011 and the wall heel plate 2012 are in contact with the foundation soil together to increase the base area of ​​contact between the wall body 200 and the foundation soil, thereby reducing the base stress, and also jointly fix and support the entire retaining wall structure, thereby increasing the overall anti-overturning stability of the retaining wall structure.

[0038] In one embodiment, if Figure 1As shown, in the same pulling wall component 1, the vertical plates 202 of the two walls 200 are arranged in parallel, and the load-bearing members 201 of the two walls 200 are arranged in parallel. The vertical plate 202 and the load-bearing member 201 are perpendicular to each other. That is to say, in the same pulling wall component 1 of this retaining wall structure, if the load-bearing member 201 is arranged in parallel on the foundation soil, the vertical plate 202 is perpendicular to the load-bearing member 201. Therefore, at this time, the vertical plates 202 of the two walls 200 are both perpendicular to the horizontal plane. After the filling space 203 between the two walls 200 is filled with soil, the entire retaining wall structure will be more stable. It can be understood that in the present invention, the vertical plates 202 of the two walls 200 in the same pulling wall component 1 can also be set not to be parallel according to the actual construction conditions, the vertical plate 202 and the load-bearing member 201 may not be perpendicular, and the load-bearing members 201 of the two walls 200 may not be parallel, as long as the retaining wall structure after the filling space 203 is filled with soil is stable and reliable. It can be understood that during actual construction, since the foundation soil is not necessarily parallel to the horizontal plane and the load-bearing member 201 is not necessarily arranged parallel to the horizontal plane, at this time, only the two vertical plates 202 need to be arranged in parallel, but the vertical plate 202 and the load-bearing member 201 do not necessarily need to be perpendicular. That is to say, in the present invention, the relative angle between the vertical plate 202 and the load-bearing member 201 needs to be determined according to the actual construction conditions.

[0039] In one embodiment, as Figure 1 shown, in the direction perpendicular to the vertical plate 202, the width of the heel plate 2012 is greater than the width of the toe plate 2011. That is to say, in this embodiment, on the same wall 200, since the heel plate 2012 is located at the bottom of the filling space 203, the soil above the heel plate 2012 will press the heel plate 2012. Therefore, in this embodiment, in the direction perpendicular to the vertical plate 202, the width of the heel plate 2012 is set to be greater than the width of the toe plate 2011 to prevent the entire retaining wall structure from overturning due to the lateral pressure generated by the filled soil. Among them, the specific width and thickness of the heel plate 2012 and the toe plate 2011 can be set according to requirements. For example, the width of the toe plate 2011 can be set to 0 m - 1.5 m, and the thickness of the toe plate 2011 can be set to 0.2 m - 1.0 m; the width of the heel plate 2012 can be set to 2 m - 7 m, and the thickness of the heel plate 2012 can be set to 0.2 m - 1.0 m.

[0040] In one embodiment, as Figure 1As shown, the wall 200 includes a buttress 204 connected between the vertical plate 202 and the wall heel plate 2012. The height of the buttress 204 can be set according to the height of the vertical plate 202. For example, the height of the buttress 204 can be equal to the height of the vertical plate 202 or slightly lower than the height of the vertical plate 202. It can be understood that the buttress 204 is a reinforcing rib connected between the vertical plate 202 and the wall heel plate 2012. The buttress 204 fixes the vertical plate 202 and the wall heel plate 2012, which can increase the overall rigidity of the retaining wall structure. A plurality of buttresses 204 are arranged on the wall 200, and the plurality of buttresses 204 are arranged in parallel and spaced apart. Further, the surface of the buttress 204 away from the vertical plate 202 is arranged at a preset inclination angle with the wall heel plate 2012. The preset inclination angle can be set according to demand, for example, set to 45-70 degrees. Specifically, the preset inclination angle can be 60 degrees. In a further embodiment, the buttress 204 may be integrally cast with the vertical plate 202 , the wall toe plate 2011 and the wall heel plate 2012 .

[0041] In one embodiment, if Figure 1 As shown, the buttress 204 is vertically arranged with the vertical plate 202 and the wall heel plate 2012. That is, in this embodiment, the vertical arrangement between the vertical plate 202 and the wall heel plate 2012 can further strengthen the structural rigidity of the wall 200.

[0042] In one embodiment, if Figure 1 and Figure 2 As shown, each of the walls 200 is provided with a through hole 205, and the retaining wall structure further includes an anchor head 300, which is fixedly connected to the pulling member 100 passing through the through hole 205, so as to fix the pulling member 100 on the vertical plate 202. That is, the anchor head 300 is a structural member for supporting and fixing the pulling member 100. In this embodiment, the two ends of the pulling member 100 pass through the through holes 205 reserved on the two walls 200 respectively, and then, after the anchor head 300 is fixedly connected to the pulling member 100 passing through the through hole 205, the anchor head 300 is subjected to the pulling force of the pulling member 100 and abuts against the side of the wall 200 away from the filling space 203, so that the pulling member 100 is stably installed between the two walls 200.

[0043] In one embodiment, the through hole 205 includes a first through hole (not shown in the figure) penetrating through the vertical plate 202; the anchor head 300 includes a first anchor head (not shown in the figure) disposed opposite to the first through hole, and the first anchor head is fixedly connected to the pulling member 100 passing through the first through hole. That is, in this embodiment, the through hole 205 may be the first through hole that only penetrates the vertical plate 202, that is, the first through hole avoids the position of the buttress 204 and directly penetrates the vertical plate 202, so as to facilitate the pulling member 100 to pass through the first through hole and be fixedly connected to the first anchor head, thereby stably installing the pulling member 100.

[0044] In another embodiment, as Figure 1 and Figure 2 shown, the through hole 205 includes a second through hole (not shown in the figure) penetrating through the buttress 204 and the vertical plate 202; the anchor head 300 includes a second anchor head (not shown in the figure) disposed opposite to the second through hole, and the second anchor head is fixedly connected to the pulling member 100 passing through the second through hole. That is, in this embodiment, the through hole 205 may be the second through hole that penetrates both the vertical plate 202 and the buttress 204. Thus, when the pulling member 100 is connected to the wall body 200, it needs to pass through the entire buttress 204 and the second through hole formed through the vertical plate 202 corresponding to the buttress 204. Further, after the pulling member 100 passes through the second through hole and extends out from the edge of the vertical plate 202 away from the buttress 204, the pulling member 100 can be fixed by the second anchor head. In this embodiment, since the second through hole passes through both the buttress 204 and the vertical plate 202, compared with the first through hole that only penetrates the vertical plate 202, the thickness of the wall body 200 penetrated by the second through hole is thicker. Thus, the pulling member 100 passing through the second through hole can withstand a greater pulling force, thereby while ensuring the structural strength of the entire retaining wall, the number of pulling members 100 can also be reduced, thereby reducing the cost.

[0045] In yet another embodiment, the through hole 205 includes a first through hole penetrating through the vertical plate 202 and a second through hole penetrating through the buttress 204 and the vertical plate 202. Similarly, the anchor head 300 also includes the above-mentioned first anchor head and second anchor head. That is, in this embodiment, the through hole 205 may include both the first through hole and the second through hole at the same time. At this time, the pulling member 100 can be arranged at any position on the wall body 200 according to requirements, which facilitates the design and layout of the pulling member 100.

[0046] In one embodiment, as Figure 1 and Figure 2As shown, the tension member 100 includes a tension cable 101 and a protective tube 102 sleeved on the tension cable 101. The protective tube 102 is installed between the two vertical plates 202, and the tension cable 101 passes through the protective tube 102 and the through hole 205 to connect the anchor head 300. Since the tension member 100 is a component connecting the two walls 200, after filling the soil in the soil filling space 203 between the two vertical plates 202, the tension force can be provided by the tension member 100 connected between the two vertical plates 202 to reduce the eccentric stress of the wall 200. In this embodiment, the tension member 100 may include a tension cable 101 installed between the two walls 200 through the anchor head 300, and a protective tube 102 sleeved on the tension cable 101 and used to protect the tension cable 101. Among them, the protective tube 102 includes but is not limited to a hollow pipeline such as a galvanized pipe that can protect the tension cable 101, and the tension cable 101 can be a steel bar or a steel strand, etc.

[0047] During construction, the wall 200 should be poured first, and then a through hole 205 should be reserved on the wall 200 for the tension cable 101 to pass through the through hole 205. After the wall 200 is poured and formed, the soil in the soil filling space 203 is filled and compacted in layers to ensure that there will be no large settlement deformation in the subsequent soil filling. Furthermore, according to the filling progress in the soil filling space 203 in the wall 200, the tension member 100 is tensioned in batches so that the tension member 100 tightens the two side walls 200 to form prestress (tension force) to jointly resist the horizontal soil pressure of the soil on the retaining wall structure. Among them, the process of tensioning the tension member 100 is specifically as follows: First, a directional drilling is carried out at a position in the soil layer in the soil filling space 203 opposite to the through hole 205 to obtain a threading hole, and then the protective tube 102 is passed through the threading hole to maintain the non-collapse of the threading hole. Then the tension cable 101 is sequentially passed through the threading hole and the through hole 205 on the wall 200. Finally, the tension cable 101 passing through the through hole 205 is fixed by connecting the anchor head 300 at both ends of the tension cable 101, thereby completing the fixed connection between the tension member 100 and the wall 200. At this time, the protective tube 102 can also protect the tension cable 101 in the soil layer in the soil filling space 203. Understandably, the fixation of the anchor head 300 to the tension cable 101 is specifically that first, the end of the tension cable 101 is fixed on the wall 200 through the anchor of the anchor head 300, and then pouring is carried out on the anchor and the end of the tension cable 101 to form a protective layer covering the anchor and the tension cable 101.

[0048] Understandably, after the tension cable 101 is installed, it will have prestress. At this time, the tension cable 101 will be in a tensioned state in the duct and contact the duct wall to generate frictional force. In a curved duct, this frictional force is greater, which will cause greater loss of the tension cable 101 and reduce the utilization rate of the tension cable 101. At the same time, it will also make the tension cable 101 more prone to damage, thereby reducing the structural strength and service life of the retaining wall structure. Therefore, in the present utility model, a threading hole is pre-oriented and perforated in the filling space 203 for embedding the protection pipe 102, thereby avoiding bending due to uneven settlement of the soil and uneven compaction during subsequent filling in the filling space 203, forming a curved duct. In this way, the prestress loss caused by the bending of the duct can be effectively reduced, the utilization rate of the tension cable 101 can be improved, and the damage of the tension cable 101 caused by soil settlement can be avoided, thereby enhancing the structural strength and service life of the retaining wall structure.

[0051]

[0052] As shown in Table 1, taking a 20m filled soil slope as an example, under the same filling parameters, comparing the engineering quantities required for the pile foundation retaining wall structure and the retaining wall structure in the present utility model (i.e., the counterfort 204 retaining wall structure shown in Table 1) for two types of retaining wall structures in a 10m length, the engineering quantity of the counterfort 204 retaining wall structure shown in Table 1 is significantly less than that of the pile foundation retaining wall structure. That is, the counterfort 204 retaining wall structure requires less materials such as concrete and steel bars under the same working conditions, and thus is more economical.

[0053] As shown in Table 2, taking a 20m filled soil slope as an example, under the same filling parameters, comparing the stabilities of the pile foundation retaining wall structure and the retaining wall structure in the present utility model (i.e., the counterfort retaining wall structure shown in Table 2). As shown in Table 2, compared with the pile foundation retaining wall structure, the anti-slip stability coefficient and anti-overturning stability coefficient of the counterfort retaining wall structure are both higher than those of the pile foundation retaining wall structure. Therefore, the overall stability of the retaining wall structure of the present utility model is higher.
