Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a multifunctional flood control retaining wall for water conservancy projects. Background Technique

[0002] A retaining wall refers to a structure that bears the roadbed or hillside soil mass to prevent its deformation and instability. It is widely used in engineering construction such as civil construction, water conservancy and hydropower, and railway transportation, and has the functions of retaining soil, retaining water, guiding water flow, and connecting the shore. For a long time, gravity retaining walls have occupied an important position in water conservancy projects, especially in railway and highway projects. In some areas rich in stone materials, stone gravity retaining walls have become widely used retaining structures in China due to the convenience of local material utilization and simple construction methods. Since gravity retaining walls mainly rely on their own weight to maintain stability, it leads to large cross-sectional dimensions and masonry works, and the cross-sectional dimensions and masonry of the retaining wall increase with the increase of the wall height. When the cross-sectional dimension increases to a certain value, the resulting base stress will exceed the bearing capacity of the foundation, thereby causing the foundation to fail and further leading to the instability of the retaining wall. With the continuous development of the economy, higher requirements for energy conservation and environmental protection have been put forward in geotechnical engineering. The retaining wall structure has developed from a support method that solely relies on its own weight to resist the earth pressure on the wall thickness to a variety of new retaining structures that adopt supports, anchorages, and reinforced composite structures.

[0003] The application number is CN201220007789.X, which discloses a multifunctional flood control retaining wall for water conservancy projects. On the basis of the retaining wall structure supported by square piles, a compaction grouting pile is vertically fixed on the side of the wall foundation, and a guide beam is horizontally fixed on the outside of the retaining wall. The sheet pile structure is used to reinforce the flood control wall from the outside. Without having to demolish the existing retaining wall, a guide beam is horizontally added and fixed on the outside of the retaining wall. The construction period is short, it is simple and easy to operate, economical and environmentally friendly, the construction cost is low, the reinforcement structure is firm and stable, and the flood control effect is acceptable.

[0004] In the above application, the wall foundation is supported and installed by square piles, and it cannot be combined in the vertical direction, which is not convenient for adjusting the height of the flood control wall after installation. Content of the Utility Model

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides a multifunctional flood control retaining wall for water conservancy projects, which includes an upper platform and a lower platform. The upper platform and the lower platform are connected by a wall toe plate. The wall toe plate is inclinedly distributed. A number of buttresses are vertically arranged on the inner side surface of the wall toe plate. A number of convex columns are arranged on the bottom surface of the lower platform;

[0007] Place the side of the toe slab with a buttress closer to the side of the earth wall. Insert the buttress side into the interior of the earth wall. Multiple buttresses divide the earth wall into multiple pieces for support, preventing the earth wall from collapsing due to the impact of floods and enhancing the overall structural strength of the earth wall.

[0008] Further, a number of slot holes are opened on the lower platform, and a number of through holes are provided on the upper platform. Columns are inserted into both the slot holes and the through holes. The bottom ends of the columns are inserted into the ground to make the retaining wall more stable.

[0009] Further, when the two retaining walls are spliced, during splicing, the lower platform overlaps above the upper platform. At the same time, a number of the slot holes correspond to a number of the through holes one by one, and columns are inserted into the mutually communicating slot holes and through holes, making the connection between the two retaining walls more secure;

[0010] The two toe slabs are stacked on top of each other to increase the height of the toe slab and adapt to earth walls of different heights. During the splicing process, the convex columns are fitted into the corresponding grooves, and the columns installed on the upper platform are fitted with another slot hole to increase the height of the toe slab. After the two toe slabs are spliced, three rows of columns are installed, and the installation and fixation of the two toe slabs are achieved through three rows.

[0011] Further, a number of grooves are provided on one side surface of the upper platform, and the convex columns are fitted into the grooves. This makes the structure of the waterproof retaining wall more secure.

[0012] Further, the side surface of the buttress is triangular.

[0013] The utility model has the following beneficial effects:

[0014] (1) The utility model makes it stable and increases the flood control height by splicing the columns with the slot holes.

[0015] (2) The grooves on the vertical wall of the utility model are spliced with the grooves on the lower table surface, and the connection is stable, increasing its stability.

[0016] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings
