Embodiment Construction

[0027] A kind of novel submerged embankment crest structure of the present invention such as figure 1 shown.

[0028] The specific implementation steps are as follows:

[0029] In the first step, according to the rigid frame (2) of the present invention, the reinforced concrete beam (10) is prefabricated in the prefabrication plant, and the steel mesh (11) of a certain density is arranged and poured on the reinforced concrete beam, so that it is enough to bear the embankment. The weight of the top main structure; the anchor holes at the four corners of the reinforced concrete beams are reserved for connecting the upper ends of the anchor chains (12); the concrete anchor blocks at the lower ends of the anchor chains are pre-placed at the foot of the submerged embankment.

[0030] In the second step, according to the embankment crest member unit (1) according to the present invention, the concrete foundation block (14) is prefabricated in the prefabrication plant to make it rea...

Abstract

The invention discloses a novel submerged dike crest structure and relates to the technical field of coastal engineering. The novel submerged dike crest structure combining flexible plant wave dissipation is composed of a dike crest member unit (1) provided with a flexible plant model and a rigid framework (2) fixed in an anchoring way. The novel submerged dike crest structure combining flexible plant wave dissipation is characterized in that a dike crest main body structure is formed by splicing a regular hexagonal member unit, and the rigid framework supports the dike crest main body structure and is fixed on the submerged dike crest through an anchor chain. Dike crest members and the rigid framework are produced in a prefabricated mode. The novel submerged dike crest structure improves the wave dissipation capability of a submerged dike by combining the good wave dissipation effect and anti-scour characteristic of flexible plants, and improves the ecological environment of water by aid of the ecological benefit of the plant model. The novel submerged dike crest structure combining flexible plant wave dissipation is simple in structural design, low in cost, convenient to construct, easy to repair and capable of remarkably improving the comprehensive technological and economic performance of current or new built submerged dikes.

Description

technical field [0001] The invention relates to the technical field of coastal engineering, in particular to a submerged embankment top structure combined with a flexible plant model. Background technique [0002] A submerged embankment is a relatively common hydraulic structure. The crest of the embankment is submerged underwater when the designed high water level is designed, and can be exposed to the water surface when the designed low water level is designed. The submerged embankment has the functions of blocking the impact of waves, maintaining the stability of the water surface in the port area, and improving the erosion and silting conditions of the water area. It can protect the safety of hydraulic structures in the port area, ensure the normal operation of the channel and the safe berthing and operation of ships. Therefore, it is widely used in various coastal engineering projects such as bank revetment, beach protection and sedimentation promotion, sea reclamation...
