Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete parts, in particular to a retaining wall structure. Background Art

[0002] A retaining wall refers to a structure that supports roadbed fill or hillside soil and prevents the fill or soil from deforming and becoming unstable. It is widely used in highway engineering, water transport engineering and water conservancy engineering. When encountering heavy rainfall and changes in the mountain soil layer, the retaining wall can promptly block the falling sand and soil to prevent the sand from affecting the river or highway on the other side of the retaining wall. The common forms of retaining walls currently under construction are solid retaining walls and box-type retaining walls.

[0003] However, of the two types of retaining walls mentioned above, the solid retaining wall requires a large amount of concrete pouring, which results in a high construction cost for the solid retaining wall. At the same time, if the volume of the solid retaining wall is too large after construction, hydration heat will occur, resulting in concrete cracking. In special circumstances, the retaining wall may fail to achieve the retaining effect or even the overall structure may break, which poses a safety hazard to the use of the solid retaining wall. The box-type retaining wall requires formwork support during construction, and the transportation and loading and unloading of the formwork will take up construction time, resulting in a long construction period. At the same time, a large amount of steel structure is also required to stabilize the box, which also results in a high construction cost for the box-type retaining wall.

[0004] As can be seen from the above, the existing technology has the problem of high engineering cost of retaining wall structure. Utility Model Content

[0027] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] In order to solve the problem of high engineering cost of retaining wall structures in the prior art, the utility model provides a retaining wall structure.

[0029] Embodiment 1

[0030] like Figure 1 to Figure 2 As shown, the retaining wall structure includes a main body 10 and a prefabricated structure 20. The main body 10 is provided with a receiving cavity, which is located in the compressive stress area of ​​the retaining wall structure. The prefabricated structure 20 contains filler, and the prefabricated structure 20 is accommodated in the receiving cavity.

[0031] By reserving a cavity for accommodating the prefabricated structure 20 during the construction of the main body 10, and selecting the weight of the filling material 21 according to the conditions of the foundation of the retaining wall before completing the construction, and filling it into the prefabricated structure 20, and then completing the construction of the main body 10, the construction period of the main body 10 and the use of raw materials are reduced, and ultimately the construction cost of the retaining wall structure is reduced.

[0032] In this embodiment, there are multiple accommodating cavities and prefabricated structures 20, the multiple accommodating cavities are arranged at intervals, and the multiple prefabricated structures 20 are arranged in a one-to-one correspondence with the multiple accommodating spaces.

[0033] In this embodiment, the main body 10 of the retaining wall structure is a concrete structure.

[0034] Specifically, multiple prefabricated structures 20 and multiple accommodating cavities are arranged correspondingly. Multiple prefabricated structures 20 are located at the compressive stress position of the retaining wall, and are avoided at the tensile stress position to prevent the prefabricated structure 20 from being damaged during use and thus causing the retaining wall effect to decrease. Furthermore, the prefabricated structure 20 has a certain thickness, that is, it has sufficient structural strength. After the prefabricated structure 20 is filled with the filling material 21, the entire prefabricated structure 20 is poured inside the main body 10 by concrete pouring. The structural strength of the prefabricated structure 20 can at least withstand the load brought by the concrete pouring on the outside of the prefabricated structure 20, preventing the prefabricated structure 20 from breaking at any position, thereby causing the filling material 21 to separate from the prefabricated structure 20, and landslides inside the retaining wall, which ultimately affects the structural strength of the entire retaining wall. In the case of heavy rainfall, the retaining wall not only fails to achieve the established technical effect of retaining soil, but also has the risk of cracking and collapse, which can easily cause large economic losses.

[0035] Furthermore, a plurality of prefabricated structures 20 are arranged inside the retaining wall. If the structural strength of the plurality of prefabricated structures 20 is insufficient during pouring, accidents may occur in the retaining wall construction, thereby increasing the construction period and wasting material costs. At the same time, the damaged prefabricated structures 20 after the concrete pouring is completed pose a great safety hazard. Once the prefabricated structures 20 are damaged, large voids will appear inside the retaining wall, which may easily lead to the risk of retaining wall collapse.

[0036] In this embodiment, a plurality of prefabricated structures 20 are arranged in layers along the height direction of the main body 10 .

[0037] Specifically, when the retaining wall is cast and put into use, there are multiple areas of compressive stress. Multiple prefabricated structures 20 are arranged in layers along the height of the main body 10, from the bottom to the top of the main body 10. This arrangement can reasonably utilize the compressive stress area of ​​the main body 10. Multiple prefabricated structures 20 are arranged, and calculated filling materials 21 are placed in the prefabricated structures 20 to reduce the concrete used in the construction of the main body 10 of the retaining wall. During the specific construction, a layer of prefabricated structures 20 is placed and cast first, and then the prefabricated structures 20 of the next layer are placed on the cast retaining wall, and then the same operation is performed. Optionally, the multi-layer prefabricated structures 20 are arranged to be offset in the vertical direction to prevent all the prefabricated structures 20 from applying pressure to the same position of the retaining wall in the vertical direction, thereby ensuring the stability of the internal structure of the retaining wall.

[0038] In this embodiment, the prefabricated structures 20 of each layer are arranged in an array.

[0039] Specifically, there is a certain distance between two adjacent prefabricated structures 20 in each layer. When one of the prefabricated structures 20 is damaged, the filling material 21 will not interfere with the other intact prefabricated structures 20. At the same time, the positions of compressive stress are reasonably utilized, and the prefabricated structures 20 close to each other will overlap with the tensile stress area, causing the prefabricated structure 20 to be affected by the tensile stress and then affect the retaining wall.

[0040] In this embodiment, the prefabricated structure 20 is adapted to the accommodating cavity.

[0041] Specifically, the prefabricated structure 20 is completely fitted with the accommodating cavity. The prefabricated structure 20 arranged in this way is more solid and reliable, and prevents the prefabricated structure 20 from moving. In this embodiment, concrete is poured to the middle position of the prefabricated structure 20 or to a position close to the top of the prefabricated structure 20, and then the filling material 21 is placed in the prefabricated structure 20, and pouring is continued after the filling is completed.

[0042] In an undisclosed embodiment of the present application, a certain amount of filling material 21 is pre-placed in the prefabricated structure 20, and then different numbers of prefabricated structures 20 are placed to achieve the purpose of reducing concrete and meeting foundation requirements.

[0043] Optionally, the prefabricated structure 20 is far away from the edge of the main body 10 , and the accommodating cavity can have sufficient strength, so that even if the edge of the main body 10 is damaged, the accommodating cavity and the prefabricated structure 20 will not be separated.

[0044] In this embodiment, the prefabricated structure 20 includes a cover plate, which is flippably disposed at the opening of the prefabricated structure 20 to block or avoid the opening.

[0045] Specifically, the prefabricated structure 20 is provided with an opening. After the filling material 21 enters the interior of the prefabricated structure 20, a cover plate is placed on the opening to prevent concrete from entering the prefabricated structure 20 during pouring, thereby reducing the use of concrete. Furthermore, the filling of the filling material 21 is completed according to the strength of the foundation where the retaining wall is located. The filling material 21 is set at a distance from the opening of the prefabricated structure 20. After the cover plate is covered, the concrete can be prevented from filling the prefabricated structure and increasing the use of concrete. Similarly, the cover plate also has sufficient structural strength to prevent the poured uncondensed concrete from crushing the cover plate due to its own weight and entering the interior of the prefabricated structure 20. The shape of the cover plate is adapted to the shape of the opening of the prefabricated structure 20, which can ensure a good sealing effect, prevent the concrete from entering the prefabricated structure 20 along the gap between the cover plate and the opening of the prefabricated structure 20, and affect the filling material 21 inside the prefabricated structure 20 through its own hydration heat effect.

[0046] In this embodiment, the prefabricated structure 20 is a cylindrical structure, and the prefabricated structure 20 is vertically disposed in the accommodating cavity.

[0047] Specifically, the prefabricated structure 20 is a vertically placed cylindrical structure. The opening of the prefabricated structure 20 is circular and can accommodate fillers 21 of different structures and shapes. At the same time, the prefabricated structure 20 is easy to process and has sufficient accommodating space. Optionally, a cover plate is provided at one end of the prefabricated structure 20 and a bottom sealing structure is provided at the other end. The shape of the prefabricated structure 20 is similar to a covered trash can. The vertical arrangement of the prefabricated structure 20 also facilitates the placement of the filler 21 into the prefabricated structure 20 and also facilitates the observation of the filling status of the filler 21.

[0048] In an undisclosed embodiment of the present application, the prefabricated structure 20 is a cylindrical structure with openings at both ends. A cover plate is provided at one end of the prefabricated structure 20, and the cover plate is connected to the edge of the prefabricated structure. The cover plate is slidably connected to the opening of the prefabricated structure 20. The connection between the cover plate and the opening is similar to a sliding door. When in use, the end of the prefabricated structure 20 without the cover plate is placed on a part of the retaining base layer that has been pre-cast, and then the cover plate is slid to fill the filling material 21 into the prefabricated structure 20. The cover plate is slid at will to achieve the effect of sealing the prefabricated structure 20, and concrete is poured to cover the entire prefabricated structure.

[0049] In this embodiment, the filling material is at least one of soil, stone, plastic, and foam material.

[0050] Specifically, plastic or foam filling materials are selected, which can not only reduce the use of concrete materials, but also solve the disposal problem of plastic and foam. At the same time, plastic and foam have lower costs and will not increase the construction cost of the retaining wall.

[0051] Furthermore, the prefabricated structure 20 also has a certain high temperature resistance. Since the accommodating cavity is formed by pouring concrete to form the prefabricated structure 20, there will be 3 to 7 days of hydration heat before the concrete dries and cools. The temperature inside the concrete will rise, and the temperature inside the prefabricated structure 20 will rise. The filling material 21, the prefabricated structure 20 and the cover plate will all be continuously affected.

[0052] Optionally, when constructing in mountainous areas, selecting suitable stones or soil materials on site to fill the prefabricated structure 20 can not only meet the bearing requirements of the foundation, but also will not increase the construction cost. Sufficient filling materials 21 can be obtained by using local materials to reduce the cost of transporting and purchasing filling materials 21.

[0053] The retaining wall of the present embodiment is square. Before construction, steel bars with a certain shape and structural strength are set first. During construction, concrete can be poured layer by layer. After the bottom layer is poured, prefabricated structures 20 are placed at intervals, and the soil and stone materials where the construction is located are placed in the prefabricated structures 20 and then covered with a cover plate. After the concrete is poured to the top of the first layer of prefabricated structures 20, a new prefabricated structure 20 is placed and poured until it reaches the height of the steel bars. The construction of the square retaining wall is completed by pouring. Compared with the traditional method, the structure of the retaining wall is designed using templates and steel bars, and a box-type retaining wall is poured in the template. This embodiment does not require the use of templates, which can speed up the construction speed. At the same time, there are differences in the template structures required for different environments. The template may be pre-processed, and the template structure and weight are relatively large, requiring a large cost for transportation. If the retaining wall is constructed in a mountainous area, there is also the problem of transportation difficulties. The loading and unloading takes a long time, and the template is also prone to damage.

[0054] Embodiment 2

[0055] The difference between the second embodiment and the first embodiment is that the retaining wall in the second embodiment is provided with a base 30, and the main body 10 is a wedge-shaped structure.

[0056] Specifically, Figure 3 to Figure 4 As shown, when the main body 10 is a wedge-shaped structure, the main body 10 is arranged on a base 30, and the base 30 is arranged on the foundation and construction is carried out after the steel bars are assembled. Accordingly, in order to facilitate the processing of the main body 10 into a wedge-shaped structure, the steel bars are assembled into a wedge shape. After the assembly is completed, the position and quantity of the prefabricated structure 20 are adjusted along the vertical direction of the main body 10.

[0057] In an undisclosed embodiment of the present application, the prefabricated structure 20 is made of stones at the construction site, and the amount of concrete used in casting the retaining wall is reduced by directly filling the stones with soil and then pouring concrete.

[0058] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by setting up a retaining wall structure including a main body 10 and a prefabricated structure 20, the main body 10 is provided with a accommodating cavity, the accommodating cavity is located in the compressive stress area of ​​the retaining wall structure, the prefabricated structure 20 is filled with filling material, and the prefabricated structure 20 is accommodated in the accommodating cavity. When the main body 10 is constructed, a accommodating cavity for accommodating the prefabricated structure 20 is reserved, and before the construction is completed, the weight of the filling material 21 is selected according to the conditions of the foundation of the retaining wall, and filled in the prefabricated structure 20, and then the construction of the main body 10 is completed, thereby reducing the construction period of the main body 10 and the use of raw materials, and finally achieving the reduction of the engineering cost of the retaining wall structure construction.
