[0002] With the rapid development of the national transportation network, there are more and more large-scale bridge projects across mountains and rivers. In particular, deep-water pile cap foundations are widely used in the foundations of super-large cross-river bridges in my country. Before the construction of the underwater cap, a cofferdam needs to be used as an auxiliary retaining structure. The construction of the cofferdam takes a long time and is difficult. Therefore, a cofferdam construction platform needs to be built before the construction of each cofferdam.

[0003] Construction materials and various construction machines, such as cranes and steel bars, need to be stacked on the cofferdam construction platform, so the cofferdam construction platform has high load-bearing capacity requirements. In the prior art, when building a cofferdam construction platform, supporting steel pipes or steel columns are usually driven into the bottom of the construction water area first, and then supporting steel plates, steel bars and other fasteners are installed on the top of the steel pipes or steel columns that are above the water surface. Usually, there are a large number of supporting steel plates, steel bars and fasteners here, and these structures are connected by bolt connection or welding when connected to each other. The processing time is long and the processing difficulty is high, which greatly prolongs the construction period and increases the workload of the construction personnel.

[0004] Therefore, it is necessary for the inventor to design a new assembled cofferdam construction platform to overcome the above problems. Summary of the invention

[0029] Embodiment 1:

[0030] like Figures 1 to 3As shown, an assembled cofferdam construction platform comprises a plurality of pile foundation brackets 1 and a plurality of support plates 2, each of the pile foundation brackets 1 being spliced ​​with one support plate 2, a docking structure being fixedly arranged between each pile foundation bracket 1 and the support plate 2, and the edges of adjacent support plates 2 being in contact; the docking structure comprises a docking groove 3 and a docking block 4 which cooperate with each other, the docking groove 3 being arranged at the top of the pile foundation bracket 1, and the docking block 4 being fixedly arranged at the bottom of the support plate 2; the docking groove 3 and the docking block 4 are truncated cone-shaped, and the inner diameter of the docking groove 3 gradually decreases from top to bottom; during operation, similarly, the pile foundation bracket 1 is first driven into the bottom of the water for fixing, and at the same time, the docking on the pile foundation bracket 1 is controlled well. The spacing of the connecting grooves 3 is controlled by controlling the spacing of the connecting blocks 4 at the bottom of the supporting plate 2 while the pile foundation support 1 is being driven. After processing, the supporting plate 2 is transported to the installation site by a transport ship, and then the supporting plate 2 is hoisted onto the pile foundation support 1 by the hoisting equipment installed, so that the connecting blocks 4 are connected to the connecting grooves 3. Under the action of the gravity of the supporting plate 2, the entire supporting plate 2 can be firmly fixed on the pile foundation support 1, and at the same time, the connecting grooves 3 will limit the connecting blocks 4 so that the supporting plate 2 will not slip when bearing weight. At this time, the connecting grooves 3 are set to have an inner diameter that gradually decreases from top to bottom, so that the connecting does not need to be precise during connecting, and connecting can still be achieved when the connecting blocks 4 and the axis of the connecting grooves 3 are slightly offset.

[0031] Each group of the pile foundation brackets 1 includes a plurality of support columns 5, the tops of the support columns 5 are fixedly provided with docking portions 6, and the docking grooves 3 are fixedly provided on the docking portions 6; connecting rods 7 are fixedly provided between adjacent support columns 5; when working, the support columns 5 are driven into the bottom of the water and fixed, and the docking portions 6, the docking grooves 3 and the support columns 5 are integrally formed. To ensure the stability of the support of the support columns 5, connecting rods 7 are further provided between adjacent support columns 5 to connect all the support columns 5 into a whole to prevent any support column 5 from loosening and causing danger; here, the spacing between the docking grooves 3 is controlled by controlling the spacing between the support columns 5, and the installation of the connecting rods 7 is achieved by bolt connection.

[0032] The support plate 2 includes a steel skeleton 8 and a concrete matrix 9, and the concrete matrix 9 is cast and formed and then wrapped around the outside of the steel skeleton 8. During operation, when the pile foundation bracket 1 is driven in, the pile foundation support plate 2 is made at the same time. The steel skeleton 8 is first fixedly connected by horizontal and vertical connections, and then concrete is poured on the outside of the steel skeleton 8. After the concrete solidifies, the support plate 2 is formed. The docking block 4 here can also be formed by concrete pouring. It only needs to replace the casting template with space reserved for the docking block 4, and control the spacing of the docking block 4 according to the spacing between the support columns 5. The processing cost of this support plate 2 is low, the processing difficulty is low, and the processing time is short, which is conducive to improving construction efficiency and shortening construction period.

[0033] There are three groups of pile foundation supports 1, and there are three support plates 2. The three support plates 2 are spliced ​​into a U-shaped support platform; when working, the U-shaped support platform can usually meet the processing work of the cofferdam.

[0034] A reinforcement structure is also provided between adjacent support plates 2; the reinforcement structure includes a steel plate 11 and a groove 10, the groove 10 is provided at the top of two adjacent support plates 2, the steel plate 11 is embedded in the groove 10, and the groove 10 is provided on the concrete base 9; during operation, since the construction platform is in the form of splicing, there may be gaps or height differences between adjacent support plates 2. In order to ensure smooth operation of construction equipment on the construction platform, steel plates 11 are provided between adjacent support plates 2 for transition, which is not only to evenly distribute the weight of the construction equipment, but also to ensure relatively smooth operation of the equipment. The groove 10 here can be pre-cast and formed when casting the support plate 2. If there is a gap or height difference during actual splicing, the steel plate 11 can be embedded between the two to keep the construction platform flat by means of grinding or the like.

[0035] Embodiment 2: Not shown in the figure, the difference between this embodiment and embodiment 1 is that: there are four groups of pile foundation supports 1, and there are four support plates 2, and the four support plates 2 are spliced ​​into a rectangular support platform; compared with embodiment 1, this embodiment only changes the shape of the construction platform, which is suitable for different construction scenes, and the rectangular construction platform can construct a larger cofferdam size.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
