Description

Technical Field

[0001] The invention relates to the technical field of retaining wall structures, and in particular to an integrally assembled retaining wall structure. Background Art

[0002] In recent years, a large number of retaining walls need to be built in river regulation, highway, railway, waterway, municipal construction projects, etc. The traditional block stone structure has problems such as difficulty in material source, poor durability, high labor intensity and low efficiency. The new materials that have emerged in recent years are also difficult to popularize on a large scale due to factors such as high cost. Relatively speaking, the traditional cast-in-place concrete structure is still widely used due to its advantages such as high rigidity and good integrity. However, the on-site construction of this type of structure often has many disadvantages such as long construction period, great impact on the surrounding environment, difficult to control construction quality, large amount of repeated work, low level of industrialization, and low labor efficiency.

[0003] The retaining wall structures in the above-mentioned projects are similar and have natural advantages of highly standardized production. Prefabricated components have significant advantages such as industrialized production, mechanized construction, high labor efficiency, and easy quality control, which better fit the natural advantages of retaining wall structures. We should increase research and engineering applications of prefabricated retaining wall structures.

[0004] In engineering practice, L-shaped concrete retaining walls are widely used due to their small size and light weight. Figure 1 The figure shows a traditional L-shaped concrete retaining wall structure, which consists of a base plate 10, a wall body 20 and a pile foundation 30. When the geological conditions are insufficient, foundation treatment or pile foundation can be used. The traditional construction process generally has two construction cycles: the base plate and the wall body. Each cycle includes steps such as tying steel bars, erecting molds, pouring concrete on site, removing molds, and concrete maintenance. There are many disadvantages, such as many construction processes, long construction period, high template costs, difficult to control construction quality, especially water-stopping quality, low labor efficiency, and slow concrete strength growth during winter construction. In recent years, prefabricated assembly technology has gradually been popularized and applied in industries such as construction, municipal bridges, and has gained rich experience. As a retaining wall structure with a simpler structure and a higher level of standardization, it is more in need of promotion and application.

[0005] Existing prefabricated retaining wall structures usually need to set deformation joints every 15m to 20m, with a width of 10mm to 25mm. Generally, there are anti-seepage requirements, and water stops are required in the joints. Due to the limitations of transportation and hoisting conditions, it is difficult to prefabricate a retaining wall unit with a length of 15m to 20m as a whole. Generally, small sections of prefabricated retaining wall units are prefabricated first, and then the small sections of prefabricated retaining wall units are spliced ​​into large sections of prefabricated retaining wall units on site, and finally the large sections of prefabricated retaining wall units are spliced ​​to form a complete retaining wall. However, this splicing method requires on-site solutions to how to simply and reliably solve the splicing problem of small sections of prefabricated retaining wall units and large sections of prefabricated retaining wall units, specifically: 1) How to splice each small section of prefabricated retaining wall unit into a large section of prefabricated retaining wall unit with a length of 15m to 20m, so that it has the same integrity as the traditional cast-in-place retaining wall structure; 2) How to set the deformation joint between two large sections of prefabricated retaining wall units to adapt to horizontal displacement and settlement and ensure the anti-seepage function.
