Description

Technical Field

[0001] The utility model relates to the technical field of municipal road drainage engineering construction, and more specifically, to a Larsen steel sheet pile construction positioning and fixing device. Background Art

[0002] As a new type of building material, Larsen steel sheet piles have played an important role in cofferdams, large diameter pipeline laying, temporary foundation pit excavation, retaining walls, embankment and bank protection projects. Larsen steel sheet piles have fast construction speed, low construction cost, and can be recycled repeatedly, which has significant environmental protection effects, greatly reducing the amount of earth excavation and concrete usage, and effectively protecting land resources. Larsen steel sheet piles bite each other through small locks and have good waterproof performance.

[0003] With the continuous development of my country's economy, urban infrastructure projects, especially the construction, reconstruction and expansion of roads, are constantly being implemented. At present, the traditional Larsen steel sheet pile construction process of municipal road drainage projects is: construction preparation → site leveling → measurement and positioning → ash line for steel sheet pile position → steel sheet pile construction → foundation pit excavation construction → trench backfilling → steel sheet pile extraction. At present, the depth of the sewage pipe foundation pit of urban road drainage projects is generally 3m-7m, and the groundwater is relatively high. Due to limited working space, Larsen steel sheet pile support is generally used. According to the traditional Larsen steel sheet pile construction process, there are the following disadvantages:

[0004] (1) The traditional methods of measuring and positioning, spreading ash lines or pulling lines are difficult to ensure the construction line of steel sheet piles, resulting in the steel sheet piles not being constructed in a straight line, affecting the construction of the purlins and internal supports, making it difficult to ensure that the support system achieves the expected effect, and posing a huge safety hazard;

[0005] (2) With traditional construction technology, the steel sheet piles are not accurately positioned and the steel sheet piles are not fully engaged, which will lead to poor water-stopping effect of the Larsen steel sheet piles and groundwater leakage, greatly affecting the construction effect and posing a major safety hazard.
