Description

Technical Field

[0001] The utility model relates to the technical field of foundation treatment engineering, in particular to a temporary slope retaining wall structure with a steel anti-slip structure. Background Art

[0002] my country has a vast territory, with many cities and populations distributed along the coast, along rivers, and along rivers. These areas are widely distributed with soft clay strata deposited in marine, lacustrine and river phases. Soft clay strata have the characteristics of poor permeability, high compressibility, low strength, high water content, and are generally buried at a shallow depth. When the thickness of the stratum is large, the structures on it are prone to large settlement and differential settlement, and the duration of settlement is often long, which significantly affects the durability of the building and reduces the normal service life of the building.

[0003] Modern buildings have the need to increase in size and design service life, but the strength, foundation bearing capacity and stability of clay soil often cannot meet the needs of new buildings. Therefore, it is necessary to treat the foundation, and drainage consolidation method is a commonly used soft clay foundation treatment measure. The principle is to set up drainage structures such as sand wells and drainage belts in the foundation, load preload above the foundation soil, so that the water in the foundation soil is discharged, the soil layer gradually settles and consolidates, and the strength of the soil layer is increased. Not only can the foundation settlement be basically completed during the ballasting stage, meeting the settlement and differential settlement limits of the building during the use stage, but also the bearing capacity and stability of the soil layer can meet the requirements of the building.

[0004] At present, loose materials such as stones and soil are mostly used for loading on the foundation. Such loose materials are naturally piled on the foundation to be treated. It is convenient to construct and economical, but it is prone to collapse accidents, which may cause property losses and casualties in serious cases. Therefore, when loose materials are used, temporary slope supports need to be set at their side positions to support the loose materials and prevent them from falling because they are too loose and lack self-stability.

[0005] However, traditional temporary slope supports often use reinforced concrete structures. Although they can ensure the safety of the support, they have high masonry costs, low mechanization levels, and long construction periods. They not only take up the compact foundation treatment time but are also highly dangerous. If a dangerous situation occurs, it will delay the construction period. At the same time, the use of reinforced concrete structures is not environmentally friendly, highly polluting, and energy-intensive. After use, they are difficult to dismantle and cannot be reused. The large amount of construction waste generated can only be directly discarded or further processed, which is not conducive to energy conservation and emission reduction. In addition, after the construction of traditional temporary slopes is completed, the plan is difficult to modify and has poor flexibility. Summary of the invention

[0006] The purpose of the utility model is to provide a temporary slope retaining wall structure with a steel anti-slip structure based on the above-mentioned deficiencies of the prior art, which realizes the rapid construction of the temporary slope retaining wall unit and improves the anti-slip performance of the slope retaining wall unit through the cooperation of C-shaped channel steel and H-shaped steel.

[0009] The two first assemblies are connected via the second assembling body to form an integral structure, and the connection transforms one of the two first assembling bodies from a semi-closed structure to a closed structure.

Among the several spliced ​​first assemblies, the first assembly located at the side position and having a semi-closed structure is closed by connecting the H-shaped steel to the side assembly.

[0029] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0030] like Figure 1-7 As shown, the marks 1-12 in the figure respectively represent: temporary retaining wall unit 1, fill 2, H-shaped steel 3, piled soil 4, integral C-shaped channel steel 5, segmented C-shaped channel steel 6, C-shaped channel steel 7, first assembly 8, side assembly 9, first assembly 10, side assembly 11, flexible mesh 12.

[0031] Embodiment 1: Figure 1As shown, the temporary slope retaining wall structure with a steel anti-slip structure in this embodiment is used in the foundation treatment of the drainage consolidation method. During the foundation treatment of the drainage consolidation method, the piled soil 4 as a pile carrier is piled on the top of the foundation to be treated to form a piled weight. The temporary slope retaining wall unit 1 in this embodiment is set at the boundary position of the foundation to be treated to support the piled soil 4.

[0032] Specifically, combined Figure 4 and Figure 5 As shown, the temporary slope retaining wall unit 1 in this embodiment includes a first assembly 8 and an H-shaped steel 3 as a second assembly. The first assembly 8 includes four C-shaped channel steels 7, and the four C-shaped channel steels 7 are connected to form a whole through a flexible mesh 12. The H-shaped steel 3 serves as a connecting piece between the first assemblies 8, and multiple first assemblies 8 can be connected and fixed.

[0033] At this time, combined with Figure 4 and Figure 5 As shown, since the flexible mesh 12 is a flexible structure, the four C-shaped channel steels 7 can be unfolded flat, which is convenient for folding, storage and transportation; and when in use, each C-shaped channel steel 7 can be erected to form a semi-enclosed structure with a rectangular cross section. When the two first assemblies 8 are assembled, the notches of the C-shaped channel steels 7 corresponding to the positions of the two first assemblies face each other, as shown in FIG. Figure 3 As shown, by arranging an H-shaped steel 3 between two C-shaped channel steels 7 , the assembly between two adjacent first assembling bodies 8 can be achieved.

[0034] In this embodiment, if Figure 5 As shown, the first assembly 8 is shown as a semi-enclosed structure with an opening on the right side in the figure, combined with Figure 4 As shown, when there are multiple first assemblies 8, each first assemblies 8 except for the side positions are closed by the assembly structure to form a filling area of ​​the fill 2. For the first assemblies 8 at the side positions, the side assemblies 9 are used for closing. The side assemblies 9 are sheet-like assemblies composed of two C-shaped channel steels and a flexible mesh connected therebetween, and their function is to make up for the opening of the first assemblies 8 at the side positions so as to complete the closure.

[0035] Combination Figure 1 and Figure 2 As shown, during the construction of the temporary slope retaining wall unit 1 in this embodiment, the H-shaped steel 3 is first inserted into the stratum for positioning, and then the first assemblies 8 are connected and assembled one by one by using the cooperation between the C-shaped channel steel 7 and the H-shaped steel 3. After completion, fill the enclosed space formed by the first assemblies 8 with backfill 2 to achieve the effect of heap loading and improve its own stability, thereby quickly building a temporary side wall retaining wall.

[0036] like Figure 3As shown, the H-shaped steel 3, which plays an anti-slip role for the temporary slope retaining wall unit 1, is inserted into a deeper position of the stratum. It bears the horizontal slip of the temporary retaining wall unit, the tension and compression effects inside and outside the retaining wall, maintains the stability of the retaining wall, and prevents the temporary retaining wall unit 1 from being greatly deformed when placed straight on the ground. At the same time, the bottom of the C-shaped channel steel is slightly inserted into the stratum beyond the flexible mesh to prevent the retaining wall from leaking soil.

[0037] In this embodiment, the C-shaped channel steel 7 can be an integral C-shaped channel steel 5 or a segmented C-shaped channel steel 6, wherein the integral C-shaped channel steel 5 refers to a C-shaped channel steel whose height matches the height of a single temporary slope retaining wall unit 1, and the C-shaped channel steel 6 refers to a plurality of C-shaped channel steel segments stacked in the height direction of a single temporary slope retaining wall unit 1.

[0038] Example 2: Comparison Figure 4 and Figure 6 As shown, the difference between this embodiment and the first embodiment is that: in the first embodiment, since the flexible mesh 12 is connected to the same surface position on the C-shaped channel steel 7, each first assembly 8 is a semi-enclosed structure with an opening on the right side in the direction shown. In this embodiment, since the flexible mesh 12 is connected to different surface positions on the C-shaped channel steel 7, a first assembly 10 is formed, and the first assembly 10 is a semi-enclosed structure with an opening on the left side in the direction shown. Referring to the assembly scheme of the first embodiment, combined with Figure 5 and Figure 6 As shown, when a plurality of first assembling bodies 10 are assembled, the first assembling body 10 located at the outermost side can be closed by the side assembling body 11 .

[0039] When the above embodiment is implemented:

[0040] like Figure 1 As shown, in order to correspond to the height of the piled soil 4, the temporary retaining wall units 1 can be accumulated and stacked in the height direction. Specifically, the positions of the C-shaped channel steels 7 of the upper and lower adjacent temporary retaining wall units 1 are set to match and correspond, and H-shaped steels 3 with a length that meets the stacking requirements are inserted into the stratum. Then, the C-shaped channel steels 7 of the upper and lower adjacent temporary retaining wall units 1 are set one by one on the H-shaped steel 3 along the height direction to achieve the cumulative stacking of the temporary retaining wall units 1 in the height direction.

[0041] When Figure 1 As shown, when two rows of temporary retaining wall units 1 are arranged on one side of the piled soil 4, the horizontal expansion of the temporary retaining wall units 1 can be adopted. Figure 4 or Figure 6 The front and rear rows of temporary retaining wall units 1 can be relatively independent, or they can be further connected by designing connectors to improve integrity.

[0042] The components of the temporary retaining wall unit 1 are prefabricated in the factory. The same type of assembly unit (the first assembly body 8 or the first assembly body 10) can be quickly connected on site through the H-shaped steel 3 to assemble into a complete temporary slope retaining wall frame, which can be recycled and reused after the construction is completed.

[0043] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
