A tourist embankment based on Qiantang River near the sea estuary

Abstract

The invention belongs to the technical field of dike-dams and particularly relates to a Qiantang River based coastal sightseeing dike-dam. To solve the problems that waves with the uncertain sizes mayknock down existing shoreside protecting devices or cast occluded foreign substances to the banks to cause injuries, the following scheme is provided that the dike-dam comprises a bunding and a concrete revetment; gear seat bins which are distributed at equal intervals are reserved on the side, close to the riverway, of the bunding, and square pipe baffles which are distributed at equal intervalsare embedded in openings, close to the gear seat bins, of the bunding correspondingly; and channel steel slide rails with opposite openings are welded in the two sides of the top end of each square pipe baffle in parallel correspondingly, and a same slide baffle is connected between the corresponding two channel steel slide rails in a sliding mode. By means of the Qiantang River based coastal sightseeing dike-dam, driving blades can be driven by driving gears to rotate by one fourth turn so that the slide baffles can rise in place, accordingly, the shoreside revetment is heightened temporarily the moment the waves reach, in addition, the slide baffles automatically fall when the waves fall, and shoreside activities of people at ordinary times are not influenced.

Description

technical field [0001] The invention relates to the technical field of embankments, in particular to a sightseeing embankment based on the Qiantang River near the sea estuary. Background technique [0002] The average speed of Qiantang River tidal surge can reach 5-6 meters per second, and the height of the river can rise by about 1 meter; the thrust of Qiantang River tide water can reach 4-7 tons per square meter, which can easily push several tons of boulders. to more than ten meters away. It is conceivable how powerful the thunderous force of the Qiantang River tide is. [0003] Nowadays, when the tides of the Qiantang River emerge, tourists will still be attacked by the waves or even injured by the waves. Although a warning line is drawn on the shore, the size and height of the waves are not constant. Some of the guardrails will be washed away, or the stones or debris mixed in the waves will be thrown tens of meters away from the shore, making it difficult to guard aga...

[0003] Nowadays, when the tides of the Qiantang River emerge, tourists will still be attacked by the waves or even injured by the waves. Although a warning line is drawn on the shore, the size and height of the waves are not constant. Some of the guardrails will be washed away, or the stones or debris mixed in the waves will be thrown tens of meters away from the shore, which makes people hard to guard against
