Embodiment 1

[0024] A comprehensive sediment treatment method for water conservancy projects, comprising the following steps

[0025] S1: Upstream interception, set up thick fences and thin fences on the upstream and downstream of the reservoir;

[0026] S2: Reservoir sand discharge, discharge the sediment in the reservoir;

[0027] S3: remove the sediment, use the suction dredge pump to suck away the sediment in the reservoir;

[0028] S4: Set up the first-level desilting tank and the second-level desilting tank, and set the sedimentation tank upstream of the reservoir.

[0029] It is further illustrated that: in step S1, the diameter of the hole on the coarse fence is 0.5-1.3mm, and the diameter of the mesh on the fine fence is 0.2-0.7mm. The speed of the water flow prevents the damage of the coarse fence and the thin fence. The thick fence can intercept the stones in the water flow, and the fine fence can intercept the tiny impurities and sediment in the water, so as to achieve a bett...

[0031] S1: Upstream interception, set up thick fences and thin fences on the upstream and downstream of the reservoir;

[0032] S2: Reservoir sand discharge, discharge the sediment in the reservoir;

[0033] S3: remove the sediment, use the suction dredge pump to suck away the sediment in the reservoir;

[0034] S4: Set up the first-level desilting tank and the second-level desilting tank, and set the sedimentation tank upstream of the reservoir.

[0035] It is further illustrated that: in step S1, the diameter of the hole on the coarse fence is 0.7-1.3mm, and the diameter of the mesh on the fine fence is 0.5-0.7mm. The speed of the water flow can prevent the damage of the thick fence and the thin fence. The thick fence can intercept the water flow and stones, and the fine fence can intercept the tiny impurities and sediment in the water, so as to achieve a better interception effect, and the density of the thin fence The density is greater than that of the thick fence, so i...

[0037] S1: Upstream interception, set up thick fences and thin fences on the upstream and downstream of the reservoir;

[0038] S2: Reservoir sand discharge, discharge the sediment in the reservoir;

[0039] S3: remove the sediment, use the suction dredge pump to suck away the sediment in the reservoir;

[0040] S4: Set up the first-level desilting tank and the second-level desilting tank, and set the sedimentation tank upstream of the reservoir.

[0041]It is further illustrated that in step S1, the diameter of the hole on the coarse fence is 0.8-1.3mm, and the diameter of the mesh on the fine fence is 0.6-0.7mm. The speed of the water flow can prevent the damage of the thick fence and the thin fence. The thick fence can intercept the water flow and stones, and the fine fence can intercept the tiny impurities and sediment in the water, so as to achieve a better interception effect, and the density of the thin fence The density is greater than that of the thick fence, so it ...

Abstract

The invention discloses a comprehensive silt treatment method for a water conservancy project. The comprehensive silt treatment method for the water conservancy project comprises the following steps that S1, upstream interception is conducted, specifically, thick fences and thin fences are arranged on the upstream and the downstream of a reservoir correspondingly; S2, reservoir desilting is conducted, wherein silt in the reservoir is discharged; S3, the silt is removed, specifically, the silt in the reservoir is sucked away through a silt suction pump; and S4, a sedimentation tank is settled, namely a primary desilting tank and a secondary desilting tank are settled at the upstream of the reservoir. According to the comprehensive silt treatment method for the water conservancy project, water can flow in the horizontal direction, flows in from one end of the primary desilting basin, flows through the primary sedimentation basin in the horizontal direction and flows out from the other end of the primary desilting basin, a sludge storage hopper is arranged at the bottom of an inlet of a horizontal flow sedimentation basin, and the basin bottom of other parts has a slope, so that the water flows out from top to bottom, the water flow speed is reduced, sediment is guaranteed, sediment sedimentation effect is improved, sediment content in the water is reduced, sediment treatment effect is improved, the water becomes clear, and cleanness of the water entering the reservoir is guaranteed.

Description

technical field [0001] The invention specifically relates to the technical field of road paving, in particular to a comprehensive sediment treatment method for water conservancy projects. Background technique [0002] As an indispensable part of modern urban construction, water conservancy projects play an important role in meeting the needs of urban flood control, irrigation, power generation and improving people's living standards and quality. While enjoying the convenience brought by water conservancy projects, people also The impact on the river environment during the construction of water conservancy projects cannot be ignored. [0003] However, during the construction of the water conservancy project, the sediment flows into the reservoir with the water, and deposits and accumulates in the reservoir. Excessive accumulation of the sediment will have a great impact on the further construction of the water conservancy project, resulting in serious reservoir siltation, aff...
