Description

Technical Field

[0001] The invention relates to the technical field of hydraulic filling engineering, in particular to an environmentally friendly drain outlet. Background Art

[0002] Reclamation engineering refers to discharging the mud-water mixture dredged by the dredger into the reclamation area through pipelines, removing the moisture in the silt, and making it useful after reaching a certain standard. The drain outlet is an important facility for discharging water. The drain outlets commonly used in reclamation areas now mainly include gate box type drain outlets, buried pipe type drain outlets, overflow weir type drain outlets, etc.

[0003] There are some shortcomings in the currently used spillways, mainly the following: First, due to improper setting, the discharge concentration is too high, resulting in excessive loss of sediment, which not only causes economic losses but also pollutes the environment; second, some spillways use reinforced concrete structures as foundations and main bodies, which are not only expensive but also cannot be reused; third, the discharge flow cannot be controlled, the water level cannot be artificially controlled, and the adaptability is poor; fourth, it is impossible to prevent the blowing of garbage, which also pollutes the environment and is more likely to cause garbage to block the spillway with the action of water flow, affecting the discharge efficiency; fifth, the lack of anti-seepage measures causes seepage and even collapse accidents.

[0004] Regarding water level adjustment, authorization announcement number CN206859239U discloses a cofferdam drain outlet, comprising a drain pipe and a drain tank. The drain tank comprises a first frame, a top plate disposed on the top side of the first frame, a drain hole disposed on the top plate, a drain pipe vertically positioned on the top plate and connected to the drain hole, and a second frame and the first frame forming a cavity, within which a drain gate is disposed. The technical problem to be solved by this drain outlet is to provide a cofferdam drain outlet with a simple structure that allows for real-time observation and adjustment of the drain height. However, steel drain gates are expensive and heavy, making them difficult to operate manually. Ordinary wooden gates are subject to the impact of water flow and lack stability.

[0005] In terms of preventing blowing and filling garbage, for example, the patent with authorization announcement number CN204199309U discloses an embedded drain outlet, which includes a base plate cast from plain concrete, a trapezoidal cavity, a drainage pipe arranged at the upper rear side of the base plate, and multiple partition walls arranged in the trapezoidal cavity. Slots are provided at the edges of the rear side of the partition walls and on the rear sides of the inner sides of the trapezoidal cavity. A steel mesh is installed in front of the slots. This embedded drain outlet can prevent blowing garbage and has a stable overall structure. However, the steel mesh is too flat. Although stairs are provided for easy cleaning, garbage will also be blocked between the front of the mesh and the stairs on both sides. It is impossible to send people to clean up the garbage at all times, and this will also affect the drainage efficiency. Summary of the Invention

[0006] In response to the above technical problems, the present invention provides an environmentally friendly drain outlet that can prevent and intercept blown-in garbage, has multiple layers of filter screens, can adjust the drainage flow rate, and can prevent seepage.

[0007] The present invention provides an environmentally friendly drain outlet, which is characterized by comprising an anti-seepage component, an outer curved filter screen, a wire filter screen, a collecting wing box, a diversion platform, a main box body, a sedimentation and energy dissipation pool, a mud pump, an inverse filter screen, a drain gate, a gate plate, a steel plate bridge, a drain pipe and a cofferdam, wherein the interior of one side of the main box body is connected to the outer curved filter screen, the interior of the other side of the main box body is provided with a drain gate, one side of the drain gate is connected to the gate plate, the other side of the drain gate is connected to the drain pipe, the drain pipe is connected to the cofferdam, a steel plate bridge is connected between the cofferdam and the main box body, the left and right sides of the exterior of the main box body are respectively connected to the collecting wing box, the outer bottom of the main box body is connected to the anti-seepage component, a sedimentation and energy dissipation pool is provided inside the main box body, an inverse filter screen is provided between the sedimentation and energy dissipation pool and the drain gate, a diversion platform is provided between the sedimentation and energy dissipation pool and the outer curved filter screen, the diversion platform is connected to the outer curved filter screen through the wire filter screen, and a mud pump is provided on the top of the sedimentation and energy dissipation pool.

[0008] The main box body includes steel pipe piles, trusses and galvanized steel plates. The steel pipe piles are connected to the trusses, and the surface of the trusses is connected to the galvanized steel plates. There are four steel pipe piles.

[0009] The sedimentation and energy dissipation pool is circular.

[0010] The sluice gate is provided with a plurality of slots.

[0011] A clamping piece is provided on one side of the gate plate, and a clamping slot is provided on the other side of the gate plate. The multiple gate plates can be spliced ​​together through the clamping piece and the clamping slot.

[0012] The anti-seepage component is a HDPE anti-seepage membrane.

[0013] The anti-filter material is preferably geotextile.

[0014] The outer curved filter screen, the steel wire filter screen and the reverse filter screen have different apertures.

[0015] The left and right ends of the outside of the main box body close to the outer curved filter screen are rounded structures, and the inside of the main box body close to the outer curved filter screen is provided with a necking.

[0016] The beneficial effects of the present invention are:

[0017] (1) Multiple layers of filter screens with different pore sizes are used to intercept garbage and sediment, and the filter screens are highly targeted at sand and silt particles of different particle sizes. The setting of the diversion platform allows the water flow to further separate the sediment, making the drain outlet permeable to water but not to sand to the greatest extent possible, so that the sediment and other materials are kept in the filling area as much as possible instead of being discharged into the sea with the water flow, reducing economic losses while protecting the environment.

[0018] (2) The outer curved filter is a curved hemispherical filter, which makes it difficult for blown-in garbage to adhere. The walls on both sides of the water inlet are rounded, which is conducive to the garbage floating into the collection wing box with the water flow for easy collection and cleaning. The constriction setting before the front water inlet will increase the flow rate and enhance the drainage efficiency.

[0019] (3) The main body is made of galvanized steel material, which is corrosion-resistant. The four steel pipe piles make the drain outlet structure stable. After use, the piles can be removed and reused, which greatly saves economic costs.

[0020] (4) The gate is equipped with gates that can be increased or decreased to change the discharge flow and height. The gates are connected by mortise and tenon joints to increase the friction between the gates, thus improving the disadvantage of ordinary wooden gates that are unstable due to water impact.

[0021] (5) Add HDPE anti-seepage membrane at the bottom of the drain outlet to effectively prevent water penetration.

[0022] (6) The steel plate bridge between the top of the cofferdam and the top of the spillway is convenient for the staff to carry out operations such as garbage cleaning and filter replacement without having to go down to the filling area. It also does not require the staff to consider the structural stress of the embedded cofferdam part as in the embedded spillway. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The main box 8 includes steel pipe piles 4, trusses and galvanized steel plates. The steel pipe piles 4 are connected to the trusses, and the surface of the trusses is connected to the galvanized steel plates. There are four steel pipe piles.

[0034] The sedimentation and energy dissipation pool 9 is circular, and the discharge gate 12 is provided with multiple slots. A clamp 131 is provided on one side of the gate plate 13, and a slot 132 is provided on the other side of the gate plate 13. Multiple gate plates 13 can be spliced ​​through the clamp 131 and the slot 132.

[0036] Example 2

[0037] When the present invention is used:

[0038] When the water flow in the filling area enters the drain outlet, the outer curved filter screen 2 first intercepts the filling garbage, boulders, boulders and other large wastes. The wastes are collected by the collecting wing box 6 under the action of the water flow with the help of the rounded corner structures on the front two sides, which is convenient for centralized cleaning. The cleaning method can be that the staff goes to the top of the drain outlet through the steel bridge 14 to salvage and clean it.

[0039] After the initial interception, the muddy and sandy water continues to flow and passes through the wire filter 5, which can filter out small gravel, gravel sand, small spherical clay and some medium-coarse sand. The water then continues to flow through the inclined flow platform 7, causing the remaining medium-coarse sand to further slide down and remain in the filling area.

[0040] After that, the water flows into the main box 8. The sedimentation and energy dissipation pool 9 at the bottom of the main box 8 has the dual functions of sedimentation and energy dissipation. The sedimentation and silt at the bottom of the sedimentation and energy dissipation pool 9 at the bottom of the main box 8 can be regularly pumped out and cleaned by a mud pump 10.

[0041] The water flow continues to pass through the geotextile filter 11 in the main box 8 to filter out small particles of sand, silt and other sediments, so as to make the discharged water retain sediment to meet the discharge standard as much as possible;

[0042] Finally, the water flows through the geotextile filter 11 in the main box 8 and flows from the drain gate 12 at the rear side of the drain outlet to the drain pipe 15 and discharges into the cofferdam 16. The discharge flow rate can be controlled by increasing or decreasing the drain gate plate 13 of the drain gate 12.
