Embodiment Construction
[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] The invention discloses a reinforcement device for offshore Larsen steel sheet piles, such as figure 1 with figure 2 As shown, it includes a U-shaped steel 1 welded on the outer wall of the steel sheet pile 8, such as image 3 As shown, it is composed of two wings 12 arranged parallel to each other and the sides 11 of the vertical two wings 12. The side 11 is welded to the outer wall of the steel sheet pile 8. The two wings 12 are vertically arranged and perpendicular to the steel sheet pile 8. The two wings 12 The opening between them is opened away from the steel sheet pile 8, and the first threaded hole and the second threaded hole are respectively horizontally opened on the two wings 12, and both the first threaded hole and the second threaded hole are used for bolts to pass through horizontally.

Abstract
The invention discloses a reinforcing device used for an offshore lassen steel sheet pile and a construction method thereof. The device comprises U steel, a supporting rod, a bolt and a fixed plate. The side portion of the U steel is welded to the outer wall of a steel sheet pile, two wings of the U steel are vertically arranged and are perpendicular to the steel sheet pile, an opening between thetwo wings is formed in a manner of being backing on to the steel sheet pile, a first thread hole and a second thread hole are formed in the two wings horizontally, and the first thread hole and the second thread hole are used for allowing bolts to horizontally penetrate through. The supporting rod is inclined, the upper end of the supporting rod is horizontally provided with a third thread hole,the lower end of the supporting rod is used for stretching into the sea water, and a bolt is used for fixing the upper end of the supporting rod between the two wings of the U steel. The fixed plate is made of steel, located below the supporting rod and in an L shape, and the vertical segment of the fixed plate is perpendicular to the horizontal segment, and is inserted into underwater silt. The supporting rod is arranged for supporting the steel sheet pile, the steel sheet pile is not prone to toppling, a fixed plate is arranged for supporting the supporting rod, and after bearing the pressure of the supporting rod, the fixed plate compacts the sludge.
Description
【Technical field】 [0001] The invention belongs to the technical field of steel sheet pile construction, and in particular relates to a reinforcement device for offshore Larsen steel sheet piles and a construction method thereof. 【Background technique】 [0002] Larsen steel sheet pile is also called U-shaped steel sheet pile. As a new type of building material, it can be used as a retaining wall for soil, water, and sand when building bridge cofferdams, laying large-scale pipelines, and excavating temporary ditches; Parapet walls, retaining walls, embankment protection banks, etc., play an important role in engineering. Larsen steel sheet piles used as cofferdams are not only green and environmentally friendly, but also have fast construction speed, low construction cost, and good waterproof function. Larsen steel sheet piles have a wide range of uses. In permanent structures, they can be used in docks, unloading yards, embankment protection banks, parapets, retaining walls,...
