Description

Technical Field

[0001] The utility model belongs to the technical field of anti-pollution of foundation pit engineering, and specifically relates to an anti-pollution baffle for retaining wall. Background Art

[0002] With the increasing shortage of urban land resources, the development and utilization of underground space has become a new development trend in urban construction projects, and foundation pit projects have increasingly come into people's sight. As one of the main means of supporting the foundation pit wall, shotcrete has long been widely used in foundation pit projects in various places. Shotcrete support is to load pre-mixed cement, sand, gravel, water and a certain amount of admixtures into a sprayer, use high-pressure air to send it to the nozzle and mix it with the accelerator, and then spray it at a high speed onto the surface of rock or concrete to form a concrete protective layer. However, in current engineering practice, when the high-speed jet formed by shotcrete hits the foundation pit wall, it is easy to cause slag splashing, resulting in environmental pollution and messy construction sites. Therefore, it is extremely important to solve the problem of pollution of foundation pit retaining walls and other components by the splashing of shotcrete slag.

[0003] Disadvantages of existing technologies: laying protective covers over a large area in the construction area requires a lot of material costs and takes up too much time, delaying the construction period; reducing the spraying speed of shotcrete to avoid splashing of slag and contaminating the foundation pit retaining wall and other components is likely to cause insufficient spraying pressure, which in turn leads to the failure to achieve the expected support effect on the foundation pit wall, causing safety hazards; existing anti-pollution baffles and other measures have poor versatility and can only provide protection in fixed positions, making it difficult to reuse in different areas; existing anti-pollution baffles and other measures have limited coverage areas and can only provide protection for a fixed range, making it difficult to adjust the protection area according to actual conditions on site.

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the present invention is not limited to the following embodiments.

[0027] Embodiment 1:

[0028] See attached Figures 1 to 5 . A retaining wall anti-pollution baffle comprises a retractable baffle assembly, an adjustable sliding assembly and a locking assembly; the retractable baffle assembly can adjust the baffle area to prevent the retaining wall from being polluted; the adjustable sliding assembly can adapt to retaining walls of different thicknesses to drive the retractable baffle assembly to slide on the retaining wall; the locking assembly is used to lock the retractable baffle assembly and the adjustable sliding assembly. As can be seen from the above structure, a retaining wall anti-pollution baffle of the utility model comprises a retractable baffle assembly, and the coverage area of ​​the baffle is adjusted by the retractability of the baffle to adapt to the baffle area required by different workplaces. The specific retractable baffle assembly comprises four first baffles 1, second baffles 2, third baffles 3 and fourth baffles 4 of the same size. The second baffle 2 is arranged adjacent to the right side of the first baffle 1 through a sliding structure. The second baffle 2 can slide to overlap with the first baffle 1 through a sliding structure. When the first baffle 1 and the second baffle 2 do not overlap at all, the coverage area is the largest. When adjustment is required, the second baffle 2 is slid to a suitable position; the third baffle 3 is The sliding structure is arranged adjacent to the lower side of the first baffle 1, and the third baffle 3 can slide to overlap with the first baffle 1 through the sliding structure. When the first baffle 1, the second baffle 2 and the third baffle 3 completely overlap, the first baffle 1, the second baffle 2 and the third baffle 3 do not interfere with each other, and the third baffle 3 increases the coverage area of ​​the overall baffle. The positional relationship between the first baffle 1, the second baffle 2 and the third baffle 3 is adjusted as needed; the fourth baffle 4 is arranged adjacent to the lower side of the second baffle 2 through the sliding structure, and slides toward the first baffle 1 following the second baffle 2. At the same time, the fourth baffle 4 can also slide to overlap with the second baffle 2 through the sliding structure. The specific sliding process of the retractable baffle assembly is as follows: Figure 1As shown, the first baffle 1, the second baffle 2, the third baffle 3 and the fourth baffle 4 are in the state where the coverage area of ​​the entire retractable baffle assembly is the largest. At this time, when the area of ​​the retractable baffle assembly needs to be adjusted, first slide the fourth baffle 4 to overlap with the second baffle 2, then slide the second baffle 2 and the fourth baffle 4 to overlap with the first baffle 1, and finally slide the third baffle 3 to overlap with the first baffle 1. At this time, the first baffle 1, the second baffle 2, the third baffle 3 and the fourth baffle 4 completely overlap, and the coverage area thereof becomes lower, so as to adapt to the work in places requiring a smaller coverage area. The setting of the retractable baffle assembly can flexibly adjust the area of ​​the protection area according to actual conditions.

It can be seen from the above structure that the second baffle plate 2 and the fourth baffle plate 4 can slide between each other. Specifically, a second side slide rail 9 is provided on the right side of the second baffle plate 2, and a second side slide rail sleeve rod 10 is provided on the right side of the fourth baffle plate 4 on the lower side of the second baffle plate 2.
