Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] see Figure 1-6 , a Larsen steel sheet pile cofferdam, including a number of Larsen steel sheet piles 1 that are spliced ​​adjacently, and a number of Larsen steel sheet piles 1 are surrounded by a U-shape, and the open end of the U-shape is against the river bank 2; a number of Larsen steel sheet piles 1 and bank 2 is the backwater side, and the outer side of some Larsen steel sheet piles 1 is the surface water side; some Larsen steel sheet piles 1 and river bank 2 are surrounded by backfill soil, and the top surface of the backfill soil is in contact with the Larsen steel sheet piles. The top surface of the pile 1 is flush, which constitutes the operation platform and the vehicle walking passage; the surface water side of each Larsen steel sheet pile 1 is sequentially fitted with a buffer layer 3 and an anti-corrosion plate 4; The j...

Abstract

The invention relates to a Larsen steel sheet pile cofferdam and a construction method thereof. The Larsen steel sheet pile cofferdam comprises a plurality of Larsen steel sheet piles which are adjacently spliced, the Larsen steel sheet piles form a U shape, and the open end of the U shape abuts against a river bank; the area defined by the Larsen steel sheet piles and the river bank is a backwater side, and the outer sides of the Larsen steel sheet piles are water-facing sides; backfill is arranged in the area defined by the Larsen steel sheet piles and the river bank, the top face of the backfill is flush with the top faces of the Larsen steel sheet piles, and an operation platform and a vehicle walking channel are formed; a buffer layer and an anti-corrosion plate are sequentially attached to the water-facing side of each Larsen steel sheet pile; and the adjacent anti-corrosion plates are overlapped at the joints of the adjacent Larsen steel sheet piles and are fixedly connected through fixing mechanisms. An anti-corrosion layer and a sponge layer are fixed to the water-facing sides, so that corrosion can be better prevented, the construction quality is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention relates to a Larsen steel sheet pile cofferdam and a construction method thereof, belonging to the field of building construction. 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. The interlocking of adjacent Larsen sheet piles can (when the sheet piles are interlocked) form a watertight structure thereby increasing the strength of the sheet pile structure. [0003] Cofferdam refers to the temporary enclosure structure built for the construction of permanent water conservancy facilities in the construction of water conservancy projects. Its function is to prevent water and soil from entering the ...
