Embodiment 1

[0020] Embodiment one: a kind of combined cofferdam construction device, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 As shown, the operation box 1 is included, the bottom of the operation box 1 is provided with a shoveling mechanism 2 for shoveling, and the two sides of the inner cavity of the operation box 1 are provided with a first limiting groove 5 for limiting the shoveling mechanism 2, The middle part of the operation box 1 is vertically provided with a second limit groove 6 for limiting the shovel mechanism 2, the top of the shovel mechanism 2 is provided with a lifting mechanism 4 for piling, and the bottom of the side of the operation box 1 is provided with a driving shovel The moving mechanism 3 of the soil mechanism 2, the bottom end of the operation box 1 is provided with a limit mechanism for fixing the position of the operation box 1, and the middle part of the top of the operation box 1 is provided with a threaded hole 7, an...

Embodiment 2

[0030] Embodiment 2. A combined cofferdam construction method. The construction steps are as follows: firstly, double-row steel pipe piles are installed, steel pipes and fasteners are used to effectively connect the steel pipe piles, and colored strips of cloth are laid inside the double-row steel pipe piles. And wooden plywood, and then put soil bags, use the self-weight of soil materials and double-row piles to further enhance the stability of the cofferdam, wood plywood plus colored strips to further improve the anti-seepage performance of the cofferdam, the soil in the soil bags adopts a combined method The cofferdam construction device excavates, and the steel pipe piles are driven into the riverbed by the shovel mechanism 2 .

[0031] The construction method of specific practical construction operations: 1. Hanging line piling: soil bag filling is excavated with a combined cofferdam construction device, and then put into the bag

[0032] 2. Mechanical piling: the area wh...

Abstract

The invention discloses a combined cofferdam construction device and construction method, comprising an operation box, a shoveling mechanism for shoveling is arranged at the bottom of the inner side of the operation box, and a shoveling mechanism for limiting shoveling is provided on both sides of the inner cavity of the operation box The middle part of the operation box is vertically provided with a second limit groove for limiting the shovel mechanism, the top of the shovel mechanism is provided with a lifting mechanism for piling, and the bottom of the operation box is provided with a drive The moving mechanism of the shovel mechanism. The invention can realize mechanical shoveling by being equipped with a shoveling mechanism to move laterally, and then solve the technical problem of requiring personnel to shovel and bag the soil to make soil bags in the prior art, improve work efficiency and save manpower; The movement can realize the function of hammering, thereby solving the technical problem of manual pile driving in the prior art, improving work efficiency and saving manpower.

Description

technical field [0001] The invention belongs to the technical field of design and improvement of river channel construction equipment and construction methods, in particular to a combined cofferdam construction device and construction method. Background technique [0002] In river dredging, due to the construction period and construction conditions, dry river dredging is generally used for construction, and cofferdams need to be erected before the dry river. Due to factors such as water flow velocity and high tide, if traditional cofferdam construction is used in some rivers, its resistance The scouring ability is slightly poor, and it is prone to collapse. [0003] Another example is the "combined cofferdam structure and construction method of concrete cofferdam and steel sheet pile cofferdam" disclosed by the Chinese invention (application number: CN201610718807.8), which includes the concrete cofferdam cast into a ring and the steel sheet pile above it Cofferdam; the top...
