In order to realize the purpose, the utility model adopts the following technical scheme:

designing a lake and river channel dredging treatment dam, which comprises a dam body, wherein the dam body is fixed at the upper end of a foundation layer, the dam body is in a trapezoidal arrangement, a plurality of fixing columns are vertically embedded at the upper end of the foundation layer far away from one side of the dam body, the upper ends of the plurality of fixing columns penetrate through the foundation layer and extend to the upper side of the foundation layer, the plurality of fixing columns are positioned in the same vertical section, the distance between every two adjacent fixing columns is the same, two connecting rods are fixed between the lower end of one side of each fixing column and the upper end surface of the foundation layer, the two connecting rods are in an inclined arrangement, a filter screen sheet is fixedly arranged between one sides of the plurality of fixing columns through bolts, the filter screen sheet is positioned between the dam body and the plurality of fixing columns, and a filling layer is laid at the upper end of the foundation layer between the filter screen sheet and the dam body;

the filling layer is including laying the cobblestone layer at the foundation bed up end, the gravel layer has been laid to the up end on cobblestone layer, the thickness on gravel layer is the same setting with the thickness on cobblestone layer.

Preferably, iron chains are horizontally arranged between the upper ends of the two adjacent fixing columns, and the iron chains are in a tightened state.

Preferably, the thickness of the filling layer is one fourth of the height of the filter screen sheet.

Preferably, a plurality of stone piers are uniformly installed on one side of the upper end of the dam body, and the distance between every two adjacent stone piers is the same.

The utility model provides a pair of dam is administered in lake river course desilting, beneficial effect lies in: this dam is administered in lake river course desilting at the more gentle low reaches of dam rivers, realizes filtering the rubbish of aquatic, prevents that rubbish from sinking the river bottom after adsorbing earth and becoming silt, causes the pollution in river course, and structural stability is high.

Drawings

Fig. 1 is the utility model provides a structural elevation of dam is administered in lake river desilting.

Fig. 2 is a structural side view of the dredging treatment dam for the lake and river channel.

Fig. 3 is an enlarged view of a filling layer of the lake and river channel dredging treatment dam of fig. 1.

In the figure: the dam comprises a stone pier 1, a dam body 2, a filling layer 3, a gravel layer 31, a cobblestone layer 32, a foundation layer 4, a filter screen sheet 5, a fixing column 6, a connecting rod 7 and an iron chain 8.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

Referring to fig. 1-2, a dam is administered in lake river desilting, including the dam body 2, the dam body 2 is fixed in the upper end of basement layer 4, the dam body 2 is trapezoidal setting, a plurality of stone mounds 1 are evenly installed to 2 upper end one sides of dam body, interval between two adjacent stone mounds 1 is the same setting, a plurality of stone mounds 1 can realize filtering with regard to the great river course rubbish of volume, later stage river course clearance personnel realize clearing up in the upper end of dam body 2, prevent that rubbish from sliding down, contact with filter screen piece 5, cause the damage to filter screen piece 5.

Keep away from the vertical a plurality of fixed columns 6 that have buried underground in 4 upper ends of the foundation of dam body 2 one side, the upper end of a plurality of fixed columns 6 all runs through the foundation of land 4 and extends to the top of foundation of land 4, a plurality of fixed columns 6 are located same vertical cross section, and the distance between two adjacent fixed columns 6 is the same setting, all be fixed with two connecting rods 7 between one side lower extreme of every fixed column 6 and the 4 up end of foundation of land, and two connecting rods 7 are the slope setting, there is filter screen piece 5 through bolt fixed mounting between one side of a plurality of fixed columns 6, and filter screen piece 5 is located between dam body 2 and a plurality of fixed columns 6, the position installation fixed column 6 in the low reaches of dam body 2, the speed of rivers is less, it is little to strike fixed column 6 and filter screen piece 5, filter screen piece 5 prevents that rubbish from getting into the river course of regular low reaches once more simultaneously, the clearance personnel can realize the clearance, avoid the silt in river course to gather.

Equal horizontal installation has iron chain 8 between two adjacent fixed column 6 upper ends, and iron chain 8 is in the state of tautening, and iron chain 8 can be fixed with the position between a plurality of fixed columns 6.
