Description

Technical Field

[0001] The invention belongs to the technical field of cleaning devices, and in particular relates to a device and method for cleaning soil between steel sheet piles. Background Art

[0002] As a common foundation pit support system, steel sheet piles are widely used in foundation pit construction. In particular, Larsen steel sheet piles, also known as U-shaped steel sheet piles, are a new type of building material that plays an important role in engineering as retaining walls, water retaining walls, and sand retaining walls when building bridge cofferdams, laying large pipelines, and excavating temporary ditches. Figure 5 As shown, the Larsen steel sheet pile has a U-shaped structure. During use, each steel sheet pile is installed symmetrically and connected by locking joints, so a cavity is formed on the excavation side.

[0003] During the trench excavation process, factors such as the internal support system, trench width, and depth usually affect the soil between the piles, making it difficult to clean the soil, posing a major safety hazard to subsequent trench construction.

[0004] The existing technologies for cleaning soil between piles mainly include mechanical and manual methods.

[0005] Mechanical cleaning usually uses an excavator to clean the foundation pit using the front tooth groove of the bucket. This method is easily affected by factors such as trench width and spacing of the internal support system, has low efficiency and has many blind areas for cleaning.

[0006] The manual cleaning method is for workers to use steel pipes, crowbars and other tools to clean out the edge of the foundation pit. This is extremely inefficient, has a limited cleaning depth and is difficult to implement under dense soil conditions. Summary of the invention

After adjusting the transverse and longitudinal positions of the drill rod, the drill rod can accurately drill into the soil between the piles.

[0017] As a preferred solution of the present invention, a rope winder is installed on the main beam, a transverse pull rope is connected to the transverse moving trolley, a wire reel is installed on the support unit, and the transverse pull rope is wound around the rope winder and the wire reel in sequence.
