[0002] Cofferdam refers to a temporary enclosure structure built for the construction of permanent water conservancy facilities in water conservancy project construction. Its function is to prevent water and soil from entering the construction site of the building, so as to drain water in the cofferdam, excavate foundation pits, build buildings, and temporarily maintain when building flood control walls along rivers and waterways. It is generally used in hydraulic structures. Except as part of formal buildings, cofferdams are generally dismantled after use. The height of the cofferdam is higher than the highest water level that may occur during the construction period.

[0003] The height of existing cofferdam devices is mostly set according to the highest possible water level. Except for special circumstances such as special weather and upstream floods that may cause the water level to rise, in most cases, it is rare or almost impossible to encounter excessive water level rise. As a result, the height of traditional cofferdam devices is too high. It is difficult to use such a high cofferdam height during the entire construction period. At the same time, its size is mostly fixed, and the cofferdam height cannot be adjusted according to actual needs. A cofferdam that is too high also requires a lot of manpower and material resources during installation and disassembly, and thus traditional cofferdam devices are not practical enough.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] Reference Figures 1 to 5 As shown, the present embodiment provides a detachable temporary cofferdam device, including a cofferdam assembly 1. When only one cofferdam assembly 1 is needed, the cofferdam assembly 1 includes an anchor seat 11, a mounting rod 12 and a plurality of guardrails 13. The anchor seat 11 is horizontally laid on the ground, and the anchor seat 11 is fixed to the ground through an anchor 14. The anchor 14 is a plug plate, which is vertically arranged at the bottom of the anchor seat 11, and the lower end of the plug plate is conical. The anchor 14 adopts a plug plate, which can provide better support in the vertical direction to the plug plate to prevent the anchor seat 11 from displacement; at the same time, the anchor 14 can also be an anchor rod, etc., which can stably anchor the anchor seat 11 to the ground at the corresponding position.

[0032] like Figure 1-5 As shown, a plurality of mounting rods 12 are vertically spaced apart on the anchor seat 11, and the mounting rods 12 are threadedly connected to the anchor seat 11 for easy disassembly and installation, and a plurality of guardrails 13 are vertically stacked on the plurality of mounting rods 12; a plurality of mounting sleeves 131 are spaced apart on one side of the guardrail 13, and a mounting sleeve 131 is slidably sleeved on a mounting rod 12, and then a plurality of guardrails 13 are slidably set on a plurality of mounting rods 12 on the same anchor seat 11, and a corresponding number of guardrails 13 can be set as needed, and at the same time, the mounting sleeves 131 on the guardrails 13 can also limit the mounting rods 12, so that the supporting strength of the overall board surface is higher.

[0033] More specifically, a plurality of pin holes 132 are arranged at intervals on the top of the guardrail 13, and a plurality of plug pins 133 are arranged at intervals on the bottom of the guardrail 13. The plug pins 133 of the guardrail 13 located at the upper side between adjacent guardrails 13 are placed in the corresponding pin holes 132 on the guardrail 13 located at the lower side. The guardrails are tightly abutted against each other, so that the plurality of guardrails 13 in the same cofferdam assembly 1 are connected and fixed to each other, which enhances the overall maintenance strength and facilitates installation and disassembly. A corresponding number of guardrails 13 can be set according to the required height. At the same time, a plurality of slots 111 are arranged at intervals on the anchor seat 11, and the plug pins 133 of the guardrail 13 located at the bottom are placed in the corresponding slots 111. The guardrail 13 located at the bottom is also tightly matched with the anchor seat 11. In actual use, there is no need to set a higher guardrail height first. When encountering special circumstances that cause the water level to rise, the guardrail 13 of the corresponding height and number can be set according to the rising water level. The installation and disassembly are very convenient and practical.

[0034] Embodiment 2:

[0035] Based on Example 1, Figure 1-5 As shown, there are several cofferdam assemblies 1, and the cofferdam assemblies 1 are distributed in a straight line, a ring, an L shape, a U shape, etc. A corresponding number of cofferdam assemblies 1 are arranged according to actual needs to form different shapes for different construction scenes.

[0036] More specifically, it also includes a seal 2 , which is arranged between adjacent cofferdam assemblies 1 and is used to seal the gap between the adjacent cofferdam assemblies 1 .

[0037] like Figure 1 , 4As shown in Figure 5, the seal 2 includes a first splint 21, a second splint 22 and a plurality of tension screws 23. The first splint 21 and the second splint 22 are symmetrically arranged on the front and rear sides of adjacent cofferdam assemblies 1. The first splint 21 and the second splint 22 are fixed to each other by the tension screws 23, and the first splint 21 and the second splint 22 are tightly fitted with the plate surfaces on the front and rear sides of the two cofferdam assemblies 1 respectively. If necessary, a rubber pad can be arranged between the first splint 21, the second splint 22 and the guardrail 13. Rubber sealing pads can also be arranged between adjacent guardrails 13, or sealant can be applied. After a plurality of cofferdam assemblies and the seal 2 are arranged, a plastic film or waterproof cloth can be wrapped on the outside to enhance the overall waterproof sealing performance. However, if there is local or small amount of leakage that does not affect the normal use of the interior, it can be pumped out with a water pump.

[0038] like Figure 4 and 5 As shown, when two adjacent cofferdam components 1 are not in a straight line, but in a curve or at an angle, Figure 5 In the scheme, the first clamping plate 21 and the second clamping plate 22 of the sealing member 2 are anisotropic and have extensions at both ends, and the extensions at both ends are sealed and connected to the two cofferdam assemblies 1.

The two ends of the support rod 3 are hinged to the seal 2 and the support seat 4 respectively. The length of the support rod 3 and the position of the support seat 4 can be adaptively adjusted according to the height of the cofferdam assembly 1 when necessary, so as to provide a good supporting foundation for the cofferdam assembly 1.

[0041] More specifically, it also includes tension members 6 , and two adjacent cofferdam assemblies 1 are connected to each other through a plurality of tension members 6 .

[0042] The tensioning member 6 includes a first hook 61, a second hook 62 and an adjusting sleeve 63, wherein the first hook 61 and the second hook 62 are symmetrically arranged at both ends of the adjusting sleeve 63, and the first hook 61 and the second hook 62 are both threadedly connected to the adjusting sleeve 63; the first hook 61 and the second hook 62 are threadedly connected to the adjusting sleeve 63 in opposite directions, and thus when the adjusting sleeve 63 is rotated forward and backward, the first hook 61 and the second hook 62 approach or move away from each other, thereby controlling the relative positions of the first hook 61 and the second hook 62, and when the two groups approach each other, the two adjacent cofferdam assemblies 1 are tightened and fixed to each other.

[0043] The first hook 61 and the second hook 62 are respectively connected to two adjacent mounting rods 12 on two adjacent cofferdam assemblies 1 .

[0044] like Figure 1 ,4 As shown in Figure 5, since the relative positions of adjacent cofferdam assemblies 1 are mainly limited by the anchor seat 11, in addition to the seal 2 and the support rod 3 that limit the upper end of the cofferdam assembly 1 vertically to the cofferdam assembly 1 plate surface, it is necessary to connect and fix the two adjacent cofferdam assemblies 1 along the general direction of the cofferdam assembly 1 through a tensioning group, thereby enhancing the connection stability between the adjacent cofferdam assemblies 1 and further enhancing the overall structural strength.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
