It should be understood that the preferred embodiments described herein are presented for purposes of illustration and explanation only and are not intended to limit the present invention.
The invention discloses a water quality treatment method of a confluent river channel before entering a dam, which is shown in figures 1-20 and comprises the following steps:
s1, connecting a mounting frame 100 with a vehicle body, and mounting a geonet roll 300 on the mounting frame 100;
s2, extending the self-adaptive dredging mechanism 200 into the river channel, wherein the self-adaptive dredging mechanism 200 is contacted with the bottom wall and the side wall of the river channel;
s3, pulling one end of the geonet roll 300 out from the lower end of the bottom wall rolling mechanism 500, and fixing the end on the bottom wall of the river channel;
s4, stretching the bottom wall rolling mechanism 500 into the river channel and pressing the bottom wall rolling mechanism on the bottom wall of the river channel, and enabling the side wall rolling mechanism 600 to be in contact with two side walls of the river channel;
s5, controlling the vehicle body to travel along the extending direction of the river course, and removing sludge and sundries on the bottom and the side wall of the river course by the self-adaptive dredging mechanism 200 to the shore, and simultaneously, gradually unreeling the geonet rolls 300, so that the unreeled geonet 400 is gradually paved on the bottom wall of the river course;
s6, periodically removing sludge and sundries which are settled at the bottom of the river and intercepted by the geonet 400.
The working principle and the advantages of the invention are as follows: according to the self-adaptive dredging mechanism 200, sludge, sundries, weeds and the like on the bottom wall and the side wall of the river channel are directly cleared to banks on two sides of the river channel, then the bottom and the side slope of the river channel are synchronously shaped through the bottom wall rolling mechanism 500 and the side wall rolling mechanism 600, in the process of shaping the bottom of the river channel, the geonet 400 is gradually paved at the bottom, and the combination of the geonet 400 and the bottom of the river channel is firmer through the compacting of the bottom wall rolling mechanism 500, so that the bottom and the side slope of the river channel are compacted and compacted through the bottom wall rolling mechanism 500 and the side wall rolling mechanism 600, the structural stability of the river channel is further ensured, the water and soil loss is slowed down, and the soil, sand and the like in the river channel are stabilized through paving the geonet 400, and the water and soil loss is further avoided. The self-adaptive dredging mechanism 200, the bottom wall rolling mechanism 500, the side wall rolling mechanism 600 and the geonet roll 300 are all arranged on the mounting frame 100, and synchronously move forward along with the advancing of the vehicle body, so that the sludge removal, the bottom of a river channel and the shaping of a side slope and the laying operation of the geonet 400 are carried out in a continuous state, and the aim of high-efficiency operation is achieved. The geonet 400 plays a role in fixing water and soil in a river channel, so that water and soil loss is prevented, and sludge, sundries and the like flowing into the river channel on the shore or upstream can be settled in the river channel, so that the sludge and the sundries in the river channel need to be removed periodically. The invention can effectively keep water and soil in the river course without dredging the dam and the river dam, namely, the silt and the sundries are fully blocked into the river course, and only dredging operation is needed for the river course, thereby reducing the dredging operation amount. In summary, the invention can effectively remove the silt, sundries and the like in the river channel before laying the geonet 400, synchronously complete the reinforcement of the river channel, and cooperate with the laying of the geonet 400 to play roles in fixing sand and resisting the flow of the silt, thereby realizing the prevention of water and soil loss in the river channel, avoiding the pollution of the lost water and soil to the water in the dam and the river dam, effectively removing the trapped silt in the river channel and improving the dredging operation efficiency.
As a preferred embodiment of the present invention, as shown in fig. 12, the geotechnical net 400 includes a net body 401, a plurality of rubber barrier sheets 402 are constructed on an upper surface of the net body 401, the rubber barrier sheets 402 are disposed at intervals along a length direction of the geotechnical net 400, and the rubber barrier sheets 402 are disposed to be inclined, which is inclined to be opposite to a direction of water flow; in this embodiment, due to the arrangement of the rubber barrier sheets 402, the rubber barrier sheets have a flow blocking effect, along with the flow of water flow, the water body is gradually energy-dissipated, and the sludge, sundries and the like carried by the water body gradually settle between the adjacent rubber barrier sheets 402, so that functions of slow flow, mud blocking and the like are achieved. In addition, the height of the rubber blocking sheet 402 is set along the length direction of the geonet 400 in a staggered manner, so that the effect of slow flow is improved, namely, after the water flow is slowly flowed by the lower rubber blocking sheet 402, a rotational flow is formed, and the rotational flow water flow can be blocked and energy-dissipating by the adjacent higher rubber blocking sheet 402, so that the water flow is prevented from flowing away with sediment due to the flowing speed of the water. As shown in fig. 13, the rubber blocking sheet 402 of this embodiment may include a plurality of blocking sheets 404, where the blocking sheets 404 may be arranged side by side, or may be staggered (irregular), so as to achieve a lateral blocking of the water flow, where the blocking degrees are different, and the lateral adjacent blocked water diversion flows interact, so that the slow flow and energy dissipation effects are more sufficient, and further the purpose of preventing water and soil loss is achieved.
