1. A method for repairing an old river course and maintaining a river course in a medium-long term is disclosed, wherein fig. 1 is a cross-sectional view after completion of a water conservancy project, and comprises a traffic road (1), a soil laying layer (2), an emergency risk avoiding culvert (3), a flood discharge area (4) and the like; the water conservancy building similar to a bridge is widely applied to the reconstruction planning of old riverways, the water conservancy building is built by a water conservancy engineering building module in a splicing and adsorption mode, and a sectional view of the building module is shown in figure 2 and comprises an adsorption groove (5), a rubber shell (6), an industrial ceramic plate (7), a steel plate layer (8), a vacuum pump (9) and the like; the building module is a hollow hexahedral square module and is constructed by selecting wear-resistant waterproof materials, so that the building module can be soaked in water for a long time without rusting and falling off; and can withstand long-term water flow scouring without peeling.

2. The method according to claim 1, wherein the method comprises the following steps: the building modules are internally provided with vacuum pumps, the outer surface of each module is provided with a right circular groove, and the building modules are used for vacuum adsorption type splicing with the grooves of other modules; the vacuum pump is used for exhausting air at the splicing position of the grooves of the modules, the splicing position of the grooves is calibrated and aligned to form a spherical area to be a vacuum area for splicing the modules, and the modules are extruded together through the grooves by means of atmospheric pressure to form firm and unbreakable connection.

3. The method according to claim 1, wherein the method comprises the following steps: the water conservancy device built by the building modules is of an inverted step-shaped structure as shown in figure 1, and the land planning design of the original river channel is referred, and the land is filled above the river channel after the large-area water conservancy device is laid, so that the original land application is recovered; for flood discharge district (4) water supply flow to pass through in water conservancy device arch hole below, the condition that the adaptation flood disaster condition period river course rises fast that notch cuttype structural design can be better realizes that river course water route "double split stream".

4. The method according to claim 1, wherein the method comprises the following steps: the structure of the water conservancy device is a hollow structure, a hollow beam column structure is formed by splicing and moving modules, the space is used as an emergency shelter for people, watertight gates are installed at openings at two ends, and the watertight gates are closed to safely shelter after people enter.

5. The method according to claim 1, wherein the method comprises the following steps: the water conservancy device can be used for comprehensively recovering the abandoned riverway, and can be used for analyzing and researching the whole height of the setting device according to flood history materials so as to successfully realize waterway diversion, and the riverway recovery engineering completed through construction can maximally contain the whole water quantity of the riverway in the rich water period and control the water flow in the underground state.

Technical Field

The invention discloses a method for repairing an old river channel and maintaining a middle-long term river channel. The invention can also be used for maintaining the conventional riverway with the riverbed continuously rising due to long-term sediment accumulation.

Background

The original river bed is abandoned after the river breaks into a river mouth, and a new channel is called channel change, and the channel change factor is mainly caused by that a large amount of silt is continuously deposited in the plain river section, so that the river bed is higher than the ground of two banks, the river breaks into a river mouth, and runoff is formed along a low-lying zone to form a new river channel; and the river diversion also has the existence of artificial factors, such as water storage and flood control, turning and straightening, artificial river channel excavation, sand excavation, water diversion and the like, so that the main river channel of the river is changed. River diversion is usually a natural disaster with great harm, and serious life and property loss is caused to people.

Disclosure of Invention

The invention aims to reduce the river diversion frequency and reduce the influence of the river diversion phenomenon on the normal life of people, and the land bridge system is built underground on the premise of keeping the life and production facilities of residents in an old river channel by using a novel water conservancy device system built by splicing building modules and using a 'waterway diversion' technical method, wherein the building starting point of the land bridge system is positioned at the river main body and is laid along the old river channel.

The method for repairing the old river channel and maintaining the middle-long term river channel comprises the following steps: and (5) paving the bedding soil above the water conservancy device, and maintaining normal agricultural production and people's trip.

The method for repairing the old river channel and maintaining the middle-long term river channel comprises the following steps: the water conservancy device is of an inverted step type land bridge structure, an emergency shelter is arranged in the water conservancy device, and the water conservancy device is a hollow large-scale shelter culvert channel.

The method for repairing the old river channel and maintaining the middle-long term river channel comprises the following steps: the water conservancy device below is the flood discharge rivers and passes through the district, and the design form that the design of falling the notch cuttype appears narrowly down wide from top to bottom, and the improvement flood discharge district that can very big limit rises the degree of holding to the water level.
