Abstract
Description
Technical Field
[0001] The utility model relates to the field of construction tools, in particular to a tool for cleaning soil between steel sheet piles. Background Art
[0002] As an indispensable and important material in modern civil engineering, steel sheet piles are widely used in engineering fields such as bridge cofferdams, deep foundation excavation, river management, embankment and bank protection, and temporary structural support. Their high strength, easy construction and reusability have greatly promoted the efficiency and safety of engineering construction. However, when the steel sheet piles are completed and the underground foundation pit excavation phase begins, a problem that cannot be ignored emerges: due to the notch structure of the steel sheet pile design, a large amount of soil and impurities are often embedded in these gaps.
[0003] These embedded soils not only occupy valuable foundation pit space and restrict the subsequent construction, but more importantly, they constitute potential safety hazards. As the foundation pit is excavated deeper, the soils may fall from the gaps in the steel sheet piles from time to time due to external disturbances or natural weathering, directly threatening the safety of workers in the foundation pit, and may even cause more serious safety accidents, such as injuring workers, destroying completed engineering structures, or affecting the stability of the foundation pit.
[0004] At present, the main cleaning method for this problem still relies on the traditional manual shovel cleaning method. Although this method is simple to operate, it is inefficient, especially when facing large or deep foundation pits. It requires a lot of manpower and takes a long time. The cleaning effect is difficult to guarantee, and there is often an incomplete cleaning situation. More importantly, during the manual cleaning process, workers need to work for a long time in a narrow, humid foundation pit where there may be a risk of falling objects. This undoubtedly increases their safety risks, and the slightest carelessness may lead to accidental injuries. Therefore, a more efficient steel sheet pile gap cleaning tool is urgently needed. Utility Model Content
[0005] The utility model mold aims to solve the problem that the linear length of the ladder cage is too long due to the deep foundation pit, resulting in poor safety and stability of the ladder cage.
[0006] The utility model aims to provide a tool for cleaning soil between steel sheet piles, comprising a trapezoidal scraper and a fixed plate, wherein the trapezoidal scraper is fixedly arranged at one end of the fixed plate, the fixed plate is fixedly connected to a bucket ear, and the shape of the trapezoidal scraper is adapted to the shape of a notch of the steel sheet pile.
[0007] As a preferred solution, the fixing plate is a U-shaped plate, and the central groove of the U-shaped plate is sleeved on the outside of the bucket ear.
[0008] As a preferred solution, the fixing plate is provided with bolt holes, bolt holes are arranged at corresponding positions of the bucket ears, and the fixing plate and the bucket ears are fixedly connected by bolts.
[0009] As a preferred solution, the thickness of the outer end of the trapezoidal scraper is 50% of the thickness of the inner end.
[0010] As a preferred solution, a reinforcing rib is provided between the trapezoidal scraper and the fixed plate.
[0011] As a preferred solution, the reinforcement ribs are T-shaped ribs.
[0012] The beneficial effects of the utility model are:
[0013] 1. The utility model uses a tool set on the bucket ear of the excavator to accurately send the trapezoidal scraper into the steel sheet pile. While the scraper moves forward, it uses its sharp edge and appropriate inclination angle to easily scrape and peel off the soil and impurities in the gap. This process is not only fast and efficient, but also can penetrate deep into the bottom of the gap and thoroughly remove the stubborn soil that is difficult to reach, significantly improving the cleaning efficiency.
[0014] 2. The utility model effectively saves labor costs. The traditional manual shovel cleaning method requires a large number of workers to work in the foundation pit for a long time, which is not only inefficient but also has great safety risks. After applying this device, workers only need to operate the excavator on relatively safe ground to complete the cleaning work, which greatly reduces the probability of personnel and machinery working in the same trench.
