Method for dike head construction and protection by air curtain type jetty

Abstract

The invention discloses a method for dike head construction and protection by an air curtain type jetty. The method is composed of a compression pump, a breather pipe and an air jetting pipe; the compression pump is arranged on an embankment, and the air jetting pipe is located at a bed of the outside of a slope type jetty; small holes are evenly distributed on the air jetting pipe, and the compression pump is connected with the air jetting pipe through the breather pipe; an outlet of the compression pump is provided with a valve, and the tail end of the air jetting pipe is provided with a blocking pipe; the air jetting pipe is in the shape of encirclement or divergence, wherein the encirclement means that the air jetting pipe is arranged at the periphery of a construction part of the slope type embankment in the form of an arc, and the divergence means that the air jetting pipe is arranged at the periphery of the construction part of the slope type embankment in the form of reverse trapezoid of evenly distributing five air jetting pipes in the middle. The method for dike head construction and protection has the following advantages: the method for dike head construction and protection is good in wave-preventing effect, simple and easy to practice; besides, the method can effectively shorten the construction duration and reduce the construction cost; the air jetting pipe is convenient to dismount, and can greatly speed up the construction speed; the method is suitable for the dike head construction and protection under the environment of deep water and short wave cycle.

Description

technical field [0001] The invention belongs to the technical field of embankment civil engineering, and in particular relates to a method for protecting embankment head construction by using an air curtain type breakwater. Background technique [0002] With the development and utilization of my country's marine resources, it has become an inevitable trend for the development of marine engineering to go to the far sea and deep sea. Under complex conditions, the protection of the breakwater construction period, especially the protection of the embankment head, is particularly important. The first principle of the embankment head protection is to minimize the construction cost under the premise of ensuring safety. The protection materials and disassembly speed of the embankment head seriously restrict the cost of the breakwater and progress. The traditional protection methods include block protection, block stone grouting at embankment head, steel truss shield, steel mesh gab...

AI Technical Summary

Problems solved by technology

The traditional protection methods include block protection, stone grouting at embankment head, steel truss shield, steel mesh gabion, etc. However, these traditional protection methods have the following disadvantages: the block protection method is expensive, and the loading and unloading cycle is long; Stone grouting is only suitable for the part above the construction water level, the effective range of protection is small, and it is easy to damage; the steel truss protective cover method has a long production cycle, difficulty in dismantling, serious deformation, low turnover times, difficult construction, and high cost; the steel mesh gabion is durable Poor performance, easy to break, light weight, easy to lose stability, and cannot be reused
