Description

Technical Field

[0001] The present invention belongs to the field of water conservancy projects, and particularly relates to a new type of wave wall based on the transformation of the original structure and its construction method. Background Technique

[0002] With the rapid development of social economy, the standards for flood control and tide defense of dike projects are increasing day by day. Many dike projects built according to low standards in the past have the need for upgrading to varying degrees, and the heightening of the wave wall is one of the important contents of the upgrading. Especially for wave walls with a large heightening value, since the anti-overturning and anti-sliding checking values of the structure cannot meet the requirements, the conventional method usually involves demolishing the original wave wall structure and then reconstructing the wave wall structure according to the elevation, structural form, etc. required by the new construction standards. This method has the following problems: (1) The original structure is not utilized, the workload of repairing the surrounding existing protective surfaces is large, and the reconstruction cost is high; (2) Restricted by flood control requirements, construction can only be carried out during periods with better wind and wave conditions, the working time is short, and the safety risk of coping with sudden extreme weather during the construction period is large.

[0003] To solve the above problems, many patents have proposed to upgrade the structure or technology of the wave wall. For example, Chinese Patent CN206204869U discloses a wave wall device that can be quickly disassembled and assembled, including a metal plate, a clamp base, an anchor chain, an anchor pile, a concave arc cornice, a tensioner, and a fixing ring. This device is arranged on the wave wall to increase the elevation of the wave wall and weaken overtopping, and can realize the dynamic adjustment of the coastal wave wall. However, due to the simple structure of this device, it is only applicable to sudden marine events and cannot form an integral long-term use with the original wave wall. Another example is Chinese Patent CN107237296A, which discloses a wave wall heightening process. By installing wooden formwork at the contact surface between the new and old concrete on both sides of part of the original wave wall and installing sliding steel formwork for the rest, and then repeating the steps of filling concrete, staying, and sliding until the entire original wave wall is heightened. This process can save materials to a great extent, reduce the labor of workers, and shorten the construction period. However, it has high requirements for aspects such as pouring and intermittent time, temperature, and formwork cleaning. Any non-rigorous parameter will lead to the failure of the entire process, that is, there are too many uncertain factors in this process, and a large amount of time and energy are required.

[0004] Therefore, how to propose a construction method for a new type of wave wall that can reduce demolition, greatly save labor costs, effectively shorten the construction time, and reduce the safety risk brought by sudden extreme weather to achieve its high efficiency and safety is a technical problem that needs to be solved urgently by those skilled in the art at present.
