A trough and dam type sand settling tank, sand mining system and sand mining method

Abstract

The invention relates to the technical field of sand excavation, in particular to a slot dam type sand-settling tank, a sand excavating system and a sand excavating method. The slot dam type sand-settling tank comprises a sand-settling tank body, wherein the bottom of the sand-settling tank body is positioned inside a river bed; the length direction of the sand-settling tank is perpendicular to the water flow direction; the bottom of the sand-settling tank body is inclined from one side to the other side; a sand pumping pit is defined at one side where the depth of the sand-settling tank body is larger; the sand pumping pit is communicated with the inside of the sand-settling tank body; the side walls of the sand-settling tank body are formed by a first trapezoidal side wall, a first rectangular side wall, a second trapezoidal side wall and a second rectangular side wall which are sequentially connected. The slot dam type sand-settling tank, the sand excavating system and the sand excavating method provided by the invention are utilized to excavate sand to allow the sand excavation operation position to be fixed; during the flood season or the flood peak period, the sand excavation operation can be conducted, and the sand excavation operation is not limited by the time. In the embodiments of the invention, the slot dam type sand-settling tank, the sand excavating system and the sand excavating method cannot damage the original appearance of a river shoal, a river bed and a river way, contaminate the water in the river way, or influence the natural environment of the river.

Description

technical field [0001] The invention relates to the technical field of sand mining, in particular to a trough and dam type sand settling tank, a sand mining system and a sand mining method. Background technique [0002] In order to obtain river sand for building materials, it is necessary to mine sand from the river beach, river bed, and bank of the river. [0003] The current method of mining sand is generally to use sand mining machinery (such as dredgers, sand pumps and excavators, etc.) grains of sand. [0004] The sand collected by the existing sand mining method is the sand naturally deposited on rivers and rivers, and the sand mining position is not fixed, and changes with the change of the quicksand deposition position. Moreover, the existing sand mining method cannot carry out sand mining operations during the flood season and flood peak when the amount of sand is the largest, and the sand mining is limited by time. [0005] Existing sand mining methods are easy ...
