Description

Technical Field

[0001] The present application relates to the technical field of retaining walls, and in particular to a push-resistant retaining wall structure. Background Art

[0002] A thrust retaining wall is a structure used to prevent soil or rock from moving. It is usually used to protect the stability of slopes, roads, railways, buildings and other infrastructure. The main function of a thrust retaining wall is to resist horizontal thrust and prevent soil or rock from sliding or collapsing due to gravity, water flow, earthquakes and other factors.

[0003] At present, the common construction method of anti-thrust retaining wall structure is still on-site masonry or cement pouring, but this method has a long construction period and consumes a lot of resources. Therefore, the existing anti-thrust retaining wall adopts a prefabricated assembled retaining wall structure, which realizes the rapid construction of the retaining wall through engineering prefabrication and on-site assembly.

[0004] However, in common prefabricated assembled retaining wall structures, the connection between two adjacent prefabricated parts is mostly through a connection method that is easy to install, such as a snap-fit ​​fit between a boss and a groove or a screw connection. These connection methods can achieve rapid construction of the retaining wall, but the strength of the connection position between the two adjacent prefabricated parts is relatively weak. When the two adjacent prefabricated parts are subjected to uneven force, it is easy to affect the structural stability of the anti-thrust retaining wall. Utility Model Content

[0005] The present application provides a push-resistant retaining wall structure, the purpose of which is to increase the strength of the push-resistant wall formed by splicing several prefabricated wall panels by increasing the connection strength between two adjacent prefabricated wall panels, thereby improving the stability of the finally formed push-resistant retaining wall structure.

[0009] Secondly, when a plurality of prefabricated wall panels are stacked in the vertical direction, a plurality of reinforcing columns on the lower side of a prefabricated wall panel are inserted into the casting groove of another prefabricated wall panel adjacent to the lower side.

[0010] The bottom of the casting trough is penetrated with casting holes. When a number of prefabricated wall panels are stacked in the vertical direction, the casting holes connect all the casting troughs.

[0012] Therefore, through the structural design of the prefabricated wall panels, cement can be injected into the stacked anti-push wall, so the connection strength between two adjacent prefabricated wall panels can be increased, thereby increasing the strength of the anti-push wall and improving the structural stability of the ultimately formed anti-push retaining wall.

[0020] By adopting the above technical solution, an exhaust hole is opened at the bottom of the casting trough, and the exhaust hole is connected to the casting trough of another adjacent prefabricated wall panel on the lower side. Therefore, when pouring cement, cement can be fed into the casting hole, and the exhaust hole can discharge the gas in the casting trough, thereby improving the strength of the solidified cement and increasing the connection strength between the two adjacent prefabricated wall panels.

[0021] Optionally, the bottom of the casting trough is further provided with an introduction groove, the casting hole is provided at the bottom of the introduction groove, and the upper side of the inner side wall of the introduction groove is inclined and extended in a direction away from the casting hole.

[0022] By adopting the above technical scheme, an inlet groove is opened at the bottom of the casting groove, and the casting hole is opened at the bottom of the inlet groove, and the inner wall of the inlet groove is inclined. The inclined setting of the inner wall makes the inlet groove present a narrowed shape with a larger upper part and a smaller lower part in the vertical direction, so that when pouring cement, it is convenient to inject cement into the corresponding casting groove.

[0023] Optionally, an oblique support rod is provided between the base plate and the prefabricated wall panel, and two ends of the oblique support rod are respectively connected to the base plate and the corresponding prefabricated wall panel.

[0051] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.

[0052] Embodiment 1:

[0053] A thrust-resistant retaining wall structure, referring to Figure 1 , including: a base plate 1 and an anti-push wall 2, the base plate 1 is horizontally arranged on the ground, and the anti-push wall 2 is vertically arranged on the upper side of the base plate 1. The anti-push wall 2 includes a plurality of prefabricated wall panels 21, and the plurality of prefabricated wall panels 21 are stacked on the base plate 1 in the vertical direction. The plurality of prefabricated wall panels 21 are spliced ​​into a retaining wall that bears horizontal thrust, thereby meeting the structural requirements of the anti-push retaining wall.

[0054] Reference Figure 2 The prefabricated wall panel 21 is in the shape of a rectangular parallelepiped. A positioning groove 211 is provided on the upper side of the prefabricated wall panel 21 . A positioning protrusion 212 is provided on the lower side of the prefabricated wall panel 21 . The positioning groove 211 and the positioning protrusion 212 are arranged opposite to each other in the vertical direction.

[0055] Reference Figure 2 and Figure 3 When a plurality of prefabricated wall panels 21 are stacked in the vertical direction, the positioning protrusion 212 on the prefabricated wall panel 21 is plugged into and matched with the positioning groove 211 on another prefabricated wall panel 21 adjacent to the lower side. The matching arrangement of the positioning groove 211 and the positioning protrusion 212 facilitates the positioning, installation and pre-connection of a plurality of prefabricated wall panels 21 during the stacking process, and prevents the adjacent prefabricated wall panels 21 from shifting during the stacking process.

[0056] Reference Figure 2 and Figure 3 The bottom of the positioning groove 211 is provided with a casting groove 213, and the casting groove 213 is communicated with the positioning groove 211. The bottom of the casting groove 213 is provided with a casting hole 214, and the casting hole 214 penetrates the bottom of the positioning groove 211.

[0057] Reference Figure 2 and Figure 3When a plurality of prefabricated wall panels 21 are stacked in the vertical direction, a plurality of casting holes 214 are connected in sequence in the vertical direction, and a plurality of casting holes 214 connect a plurality of casting grooves 213. Therefore, after a plurality of prefabricated wall panels 21 are stacked, cement is injected through the casting holes 214 of the uppermost prefabricated wall panel 21, so that the cement fills all the casting grooves 213 and casting holes 214 in sequence from bottom to top, and after the cement is solidified, the cement can fill the gap between two adjacent prefabricated wall panels 21, so that the stability of the connection between the two adjacent prefabricated wall panels 21 can be increased, and the entire anti-thrust wall 2 can form a stable whole.

[0058] Specifically, when pouring mud, several prefabricated wall panels 21 can be fixed by templates or steel frames to prevent the prefabricated wall panels 21 from shifting during the cement curing process, which is not conducive to the stability of the anti-thrust wall 2. In order to increase the strength between the prefabricated wall panels 21, a steel cage can be installed in the pouring hole 214 before pouring, and then pouring is carried out, thereby improving the strength of the final anti-thrust wall 2.

[0059] Reference Figure 3 The bottom of the casting trough 213 is provided with an introduction trough 215, and the casting hole 214 is provided at the bottom of the introduction trough 215, and the casting hole 214 is connected with the corresponding introduction trough 215. The introduction trough 215 is in a vertically large and small contracted shape. Specifically, the inner side wall of the introduction trough 215 is inclined in the vertical direction, and the upper side of the inner side wall of the introduction trough 215 is inclined and extended in a direction away from the casting hole 214. Therefore, the setting of the contracted introduction trough 215 facilitates the introduction of cement into the casting hole 214, and further facilitates the cement to fill all the casting troughs 213 in sequence from bottom to top.

[0060] Reference Figure 3 An exhaust hole 216 is formed through the bottom of the casting trough 213 , and the exhaust hole 216 and the casting hole 214 are spaced apart along the length direction of the prefabricated wall panel 21 .

[0061] Reference Figure 3 When a plurality of prefabricated wall panels 21 are stacked in the vertical direction, a plurality of exhaust holes 216 are connected in sequence in the vertical direction, and a plurality of exhaust holes 216 connect a plurality of casting grooves 213. When pouring cement, the exhaust holes 216 can exhaust the air in the casting grooves 213, thereby improving the curing effect of the cement and ultimately improving the strength of the anti-thrust wall 2.

[0062] Reference Figure 2 and Figure 3A plurality of reinforcing columns 217 are disposed on the lower side of the positioning protrusion 212, and the plurality of reinforcing columns 217 are fixedly connected to the positioning protrusion 212, and the plurality of reinforcing columns 217 are inserted into the corresponding casting grooves 213, and the lower side of the reinforcing columns 217 is spaced from the bottom of the corresponding casting grooves 213. During the process of pouring cement, the reinforcing columns 217 can increase the connection stability between the cement and the prefabricated wallboard 21, thereby improving the strength of the final anti-thrust wall 2.

[0063] Reference Figure 3 The push-resistant wall 2 further includes a closed cover plate 22, which is located on the upper side of the uppermost prefabricated wall panel 21. The closed cover plate 22 is plugged and matched with the positioning groove 211 of the uppermost prefabricated wall panel 21 in the vertical direction, and the closed cover plate 22 closes the positioning groove 211. Therefore, after pouring cement, the closed cover plate 22 is placed on the uppermost prefabricated wall panel 21, and after the cement is cured, the closed cover plate 22 and the corresponding prefabricated wall panel 21 are cured into a whole, so that the entire push-resistant wall 2 has excellent sealing and waterproof properties.

[0064] Reference Figure 3 The base plate 1 is provided with a first auxiliary groove 11, which has the same structure as the positioning groove 211, and the positioning protrusion 212 on the lowermost prefabricated wall panel 21 is plugged into the first auxiliary groove 11.

[0065] Reference Figure 3 The bottom of the first auxiliary groove 11 is provided with a second auxiliary groove 12, and the second auxiliary groove 12 has the same structure as the casting groove 213. The reinforcing column 217 on the lowermost prefabricated wall panel 21 is inserted into the second auxiliary groove 12, and the casting hole 214 and the exhaust hole 216 of the lowermost prefabricated wall panel 21 are both connected to the second auxiliary groove 12. Cement can also be poured in the second auxiliary groove 12, thereby improving the connection strength between the base plate 1 and the anti-thrust wall 2.

A clamping seat 4 is pre-buried on the side of the prefabricated wall panel 21 and the base plate 1 facing the oblique support rod 3. A clamping groove 41 is provided on the clamping seat 4. The two ends of the oblique support rod 3 are respectively plugged and matched with the corresponding clamping grooves 41, and the oblique support rod 3 is rotatably connected to the inner wall of the clamping groove 41. The oblique support rod 3 and the clamping seat 4 are connected by bolts. Through the cooperation of the clamping seat 4 and the oblique support rod 3, several supports for strengthening the anti-pushing wall 2 can be formed.

[0068] The implementation principle of the embodiment of the present application is: a plurality of prefabricated wall panels 21 are stacked to form an anti-push wall 2. After the splicing is completed, cement is poured so that the cement fills the gap between the base plate 1 and the prefabricated wall panel 21 and the gap between two adjacent prefabricated wall panels 21. After the cement solidifies, a stable connection is formed between the base plate 1 and the prefabricated wall panel 21 and between two adjacent prefabricated wall panels 21, thereby improving the strength of the anti-push retaining wall itself.

[0069] Embodiment 2:

[0071] Reference Figure 4 and Figure 5 A horizontal connecting component 23 is provided on the prefabricated wall panel 21, and the horizontal connecting component 23 includes a first connecting plate 231 and a second connecting plate 232, and the first connecting plate 231 and the second connecting plate 232 are respectively located on both sides of the length direction of the prefabricated wall panel 21, and the first connecting plate 231 is located on the upper side of the second connecting plate 232 along the vertical direction. A connecting groove 233 is opened on the lower side of the first connecting plate 231, and a connecting column 234 is provided on the upper side of the second connecting plate 232.

[0072] Reference Figure 4 and Figure 5 When several prefabricated wall panels 21 are spliced ​​in sequence along their own length direction, the first connecting plate 231 is located on the upper side of the second connecting plate 232 of another adjacent prefabricated wall panel 21, and the connecting groove 233 on the first connecting plate 231 is plugged into and matched with the connecting column 234 on the corresponding second connecting plate 232.

[0073] Therefore, the connection column 234 and the connection groove 233 can realize the connection between the prefabricated wall panels 21 spliced ​​in the horizontal direction.

A second through hole 236 is formed on the second connecting plate 232, and the second through hole 236 vertically penetrates the second connecting plate 232 and the connecting column 234.

[0076] At this time, cement is injected into the first through hole 235 and the second through hole 236, and after the cement solidifies, the connection strength between the first connecting plate 231 and the second connecting plate 232 can be increased. In order to increase the strength between two adjacent prefabricated wall panels 21 in the horizontal direction, a steel cage can be installed into the corresponding first through hole 235 and the second through hole 236 before pouring, and then pouring is performed, thereby improving the strength of the final anti-thrust retaining wall.
