Description

Technical Field

[0001] This utility model relates to the field of retaining wall construction technology, specifically to a safe operating platform for retaining wall grouting. Background Technology

[0002] "Retaining wall grouting" refers to an important post-construction process for treating the mortar joints between blocks during the construction of retaining walls (usually brick, stone, or concrete block retaining walls). It not only beautifies the wall surface but, more importantly, enhances the density, waterproofing, and durability of the mortar joints, thereby improving the structural stability and service life of the entire retaining wall.

[0003] The main purpose of grouting is to fill any tiny gaps and loose areas that may exist during masonry construction, forming continuous and full mortar joints. This effectively prevents rainwater and surface water from seeping into the wall, avoiding freeze-thaw damage, internal corrosion (for bricks and stones), or steel reinforcement corrosion (for reinforced masonry). Furthermore, dense mortar joints can better resist wind and rain erosion, freeze-thaw cycles, and chemical corrosion, extending the life of the retaining wall. Full mortar joints also make the bonding between blocks stronger, helping to evenly transfer loads and improve the overall rigidity and shear strength of the wall. They also make the mortar joint lines clear, neat, and uniform, improving the appearance. At the same time, the grouting process itself has a certain compaction and smoothing effect on the surface mortar, making it denser and more resistant to erosion.

[0004] Chinese patent application number 202210198292.9 discloses a construction method for a fine aggregate concrete masonry retaining wall. The disclosed construction method includes the following steps: surveying and setting out; excavation of the foundation pit; pouring of the foundation layer; masonry of the retaining wall and installation of a high retaining wall vertical moving material transport platform; construction of a three-dimensional composite drainage net with a face-mounted, pressure-fixed system; grouting construction using a cantilevered operating platform scaffolding system and a mobile simple formwork auxiliary grouting device. The materials can be reused, ensuring the safety of personnel, greatly improving the aesthetics of the grouting, and increasing the construction speed while saving time. The three-dimensional composite drainage net with a face-mounted, pressure-fixed system, with steel mesh fixed at both ends of the drainage net, can effectively compact and fix the drainage net, improving the drainage effect.

[0005] In the aforementioned prior art, scaffolding is erected on the outside of the retaining wall, and workers complete the grouting of the facing concrete blocks on the scaffolding. However, when the retaining wall is long, scaffolding needs to be erected along the length of the retaining wall, which results in a large workload, low work efficiency, poor scaffolding stability, and a risk of overturning. Furthermore, in areas with poor geological conditions, ground hardening is also required, which increases costs. Utility Model Content

[0027] Furthermore, the ladder cage 2 is bolted to the opposite ends of the platform body 1, thus supporting the platform body 1. The ladder cage 2 at both ends of the platform body 1 can be considered as an extension of the platform body 1, thereby increasing the construction area of ​​the platform body 1. Several unit bodies 3 are fixedly connected by bolts, thus realizing the detachable connection of the unit bodies 3. The climbing ladder 303 is set inside the unit body 3, and the construction personnel can climb the climbing ladder 303 to different heights of the unit body 3, and then enter the corresponding platform body 1 for construction. The setting of several unit bodies 3 facilitates the installation and disassembly of the work platform, thereby improving the efficiency of assembly and disassembly and reducing the intensity of work. At the same time, a base 4 is also provided at the bottom of the ladder cage 2. During installation, the base 4 is placed on the ground, and the ladder cage 2 is installed on the base 4, so that the work platform can be used on ground with different geological conditions without the need for ground hardening treatment, ensuring the stability of the work platform.

[0028] Each unit 3 includes a frame structure 301 and a support plate 302. The frame structure 301 includes several columns 3011 and crossbars 3012 connecting adjacent columns 3011.
