Description

Technical Field

[0001] This utility model belongs to the field of foundation pit construction technology, and in particular relates to a water-retaining device for Larssen steel sheet pile support. Background Technology

[0002] Larssen sheet piles have become an important component of foundation pit support due to their advantages such as simple equipment, convenient construction, low project cost, and good water tightness. However, during the implementation of Larssen sheet pile support, the fixed length of the sheet piles and the high cost of splicing them inevitably lead to the pile tops being flush with or below the ground level. This causes surface water to easily flow into the foundation pit and enter the ground through the gaps between the piles and the soil, increasing the lateral pressure on the soil and potentially causing foundation pit instability. This poses many hidden dangers to the safety and quality of the project construction.

[0003] The existing method of water retention in foundation pits mainly involves building brick water-retaining platforms around the foundation pit. This method takes a long time to build, and the water-retaining platforms need to be dismantled after construction is completed. The materials cannot be reused, resulting in a huge waste of materials and the generation of construction waste. Utility Model Content
