River dredging device

Abstract

The invention discloses a river dredging device, and relates to the technical field of river dredging. The river dredging device comprises a dragging and carrying platform and further comprises a dredging cover with the lower end being open, a barrier plate obliquely fixed to the bottom of the front end of the dredging cover, and supporting wheels evenly distributed on the left side and the right side of the dredging cover. A silt storage box is fixedly mounted on the dragging and carrying platform. The dragging and carrying platform is connected with the dredging cover through a cable. A spring expansion plate is mounted at the bottom of the rear side wall of the dredging cover in a matched mode. A silt removing device and a conveying device are arranged in the dredging cover. The silt removing device comprises a transfer box matched with the rear side wall of the dredging cover, a high-pressure air pump fixed to the top of the dredging cover, and an electric push rod fixed to the top end of the interior of the dredging cover. The river dredging device has the beneficial effects that the application range is wide, the construction process is simple, the construction efficiency is high, and the influence on river water can be reduced.

Description

technical field [0001] The invention relates to the technical field of river dredging. Background technique [0002] Traditional river dredging methods are divided into wet and dry methods. Wet dredging is a method of dredging by construction machinery such as large ships when there is river water in the river channel; dry dredging is a method that facilitates dredging by construction machinery such as excavators after the river water is pumped out. The wet method is suitable for rivers with large basins and large water volumes, while the dry method is suitable for rivers with small water volumes. Therefore, it is often necessary to choose different dredging methods according to the actual situation of the river. Therefore, the two dredging methods have obvious limitations. . [0003] In addition, the wet method also has problems such as easy to disturb the water quality during the dredging process, which will affect the survival of fish and shrimp in the river, and a larg...

Problems solved by technology

The wet method is suitable for rivers with large basins and large water volumes, while the dry method is suitable for rivers with small water volumes. Therefore, it is often necessary to choose different dredging methods according to the actual situation of the river. Therefore, the two dredging methods have obvious limitations.

[0003] In addition, the wet method also has problems such as easy to disturb the water quality during the dredging process, which will affect the survival of fish and shrimp in the river, and a large amount of water will be brought out by the dredging, resulting in low dredging efficiency. Compared with the wet method, although the dry method can eliminate The silt effect is better, and there is less water residue in the silt, but there are still problems that the construction process is complicated and is greatly affected by the terrain
