Problems solved by technology

For the double-row steel sheet pile enclosure structure, steel bars are usually used to tie them, but their rigidity is too small to coordinate the common deformation of the steel sheet piles, so there is currently no effective method for installing rigid frame beams

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] like figure 1 , 2 As shown, the section of the Larsen steel sheet pile 6 is trapezoidal, and a trapezoidal groove is formed on its inner side, and locks are provided at both ends, and several Larsen steel sheet piles 6 are connected by locks to form a row of Larsen steel sheet piles.

[0025] In the present invention, as shown in the figure, there are two rows of Larsen steel sheet piles, which are the front row of Larsen steel sheet piles and the rear row of Larsen steel sheet piles. The crown beam is set, and the crown beam of the front Larsen steel sheet pile and the crown beam of the rear Larsen steel sheet pile are connected to each other through horizontal supports to form a horizontal rigid frame beam.

[0026] The crown beam includes a rear steel plate 1 and a front steel plate 2 arranged on the rear side and the front side of the Larsen steel sheet pi...

Abstract

The invention relates to a double-row larssen steel sheet pile rigid-frame beam. A double-row larssen steel sheet pile is composed a front-row larssen steel sheet pile unit and a rear-row larssen steel sheet pile unit, and the upper portions of both the front-row larssen steel sheet pile unit and the rear-row larssen steel sheet pile unit are provided with crown beams; the double-row larssen steelsheet pile is characterized in that each crown beam is composed of steel sheets arranged at the front and the rear of the corresponding larssen steel sheet pile unit, and the steel plates are provided with reinforcing ribs, which extend into grooves formed in the corresponding larssen steel sheet pile unit and connect the steel plates at the front and the rear of the larssen steel sheet pile unitinto the crown beam; the crown beam of the front-row larssen steel sheet pile unit and the crown beam of the rear-row larssen steel sheet pile unit are connected through horizontal supports to form ahorizontal rigid-frame beam. The double-row larssen steel sheet pile rigid-frame beam can enhance integrity of the steel sheet pile, coordinates deformation of the front-row larssen steel sheet pileunit and the rear-row larssen steel sheet pile unit, and greatly improves the rigidity; after being used, the double-row larssen steel sheet pile rigid-frame beam can be disassembled for recycling andreutilization.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a double-row Larsen steel sheet pile rigid frame beam and an installation method thereof. Background technique [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 protection and other projects. The Larsen steel sheet pile has fast construction speed, low construction cost, and can be recycled repeatedly, which has a significant environmental protection effect, greatly reduces the amount of earthwork excavation and concrete consumption, and effectively protects land resources. Larsen steel sheet piles interlock with each other through small locks, which have good waterproof performance. [0003] In large-scale foundation pits or foundation pits with irregular planes, since internal support cannot be set, a...
