Problems solved by technology

[0002] When carrying out cofferdams in small water depths, some steel sheet pile cofferdams are used. The disadvantages are: the construction is more complicated, the operation time is longer, and piling is required, which destroys the landform
[0003] Some adopt cage cofferdam, its disadvantages are: the watertight effect is not good, and it cannot adapt to the slope of any slope;
[0004] Some use concrete cofferdams, but its disadvantages are: the construction is more difficult, it takes a long time to work, and it cannot be reused

Embodiment 1

[0051] A self-propelled cofferdam device that can adapt to the slope, such as figure 1 As shown, it includes M cofferdam boxes 1 and two slope watertight devices 2, where M is determined according to the actual length of the cofferdam;

[0052]The cofferdam box 1 includes a box body 3, a connecting device 6 and a bottom watertight device 7, wherein the connecting device 6 is installed on both sides of the box body 3, and is used to sequentially connect M cofferdam boxes 1 into a cofferdam box group; image 3 As shown, the bottom watertight device 7 is installed on the bottom surface of the box body 3;

[0053] The bottom watertight device 7 includes a second pressure block 15, a second watertight rubber 16 and a second water bag 17, wherein the second watertight rubber 16 is installed around the bottom of the cofferdam box 1 and forms a circle, as Figure 6 As shown, the second water bladder 17 and the second pressure bearing block 15 for auxiliary pressure bearing are instal...

Embodiment 2

[0069] A method for using a self-propelled cofferdam device based on an adaptable slope, comprising the following steps:

[0070] In the area to be cofferdamed, according to the actual length of the cofferdam to be coffered, the M cofferdam boxes 1 are spliced ​​into the required length through the connecting device 6 to obtain the cofferdam box group;

[0071] Use the water pump 5 to inject water into each cofferdam box 1, so that the cofferdam box group sinks to the bottom of the water, wherein the water pump 5 is installed inside the box body 3 of the cofferdam box 1;

[0072] After the cofferdam box group sinks into the bottom of the water, the second watertight rubber 16 contacts and compresses the bottom of the river bed until the second pressure bearing block 15 contacts the bottom of the river bed, wherein the second pressure bearing block 15 acts as an auxiliary pressure bearing, Reduce the effect of the cofferdam box on the pressure of the second water bag and the se...

Abstract

The invention provides a self-propulsion cofferdam device capable of adapting to the slope surface. First water bags of slope surface watertight devices are filled with water, through the self-weight, variability and flowability of the water, the spaces between cofferdam boxes and the slope surface are filled with the first water bags, thus longitudinal water tightness of the cofferdam boxes and the slope surface is achieved, and according to the deformability and elasticity of the first water bags, the self-propulsion cofferdam device can flexibly adapt to the slope surfaces of different gradients. Meanwhile, the spaces between the cofferdam boxes and the riverbed bottom are filled through bottom watertight devices, and horizontal water tightness of the cofferdam device and the riverbed bottom is achieved; and in short, the whole device is simple in structure, easy to operate, short in building time and capable of being recycled and efficiently and quickly conducting cofferdam.

Description

technical field [0001] The invention belongs to the field of cofferdams, and in particular relates to a cofferdam device capable of adapting to slopes and a method for using the same. Background technique [0002] When carrying out cofferdams in small water depths, some steel sheet pile cofferdams are used. The disadvantages are: the construction is more complicated, the operation time is longer, and piling is required, which destroys the landform. [0003] Some adopt cage cofferdam, its disadvantages are: the watertight effect is not good, and it cannot adapt to the slope of any slope; [0004] Some use concrete cofferdams, but its disadvantages are: the construction is relatively difficult, the operation time is long, and it cannot be reused. Contents of the invention [0005] In order to solve the above problems, the present invention provides a self-propelled cofferdam device that can adapt to slopes. The cofferdam device uses its own weight and water pockets to reali...
