PRE-FABRICATED WATER CONTROL SLUICE GATE SYSTEM WITH ANTI-SEDIMENTATION FUNCTION

Description

Technical field of the invention

[0001] The present invention relates to sluice gates.

Background of the invention

[0002] Sluice gates are used selectively to control water flow from one area of a channel to another by opening or closing off the channel to the water flow.

[0003] The frame/foundation of the sluice gate is cast directly at the application site of the sluice gate. Hence, the construction time is long, as the cement needs to settle and harden before a gate member can be installed therein. The hardening of the cement may be affected by the weather conditions, resulting in a frame/foundation of poor quality and strength. Furthermore, sedimentation prevents the functioning of the sluice gate.

[0004] A pre-fabricated water control sluice gate system according to the preamble of claim 1 is known from EP3228753 A1.

[0005] It is therefore desirable to provide a system, which can eliminate some or all of the above problems.

Description of the invention

[0006] Claim 1 defines a pre-fabricated water control sluice gate system according to the invention.

[0007] The channels of a first type and/or the channels of a second type use the water pressure difference across the gate member to flush water through the channels, thereby removing sediments that would otherwise block the functioning of the sluice gate.

[0008] In one or more embodiments, a part of the base panel is configured as a lower gate member extending between the two side panels.

[0009] In one or more embodiments, the frame is a pre-cast reinforced concrete frame. The term "pre-cast" as used throughout this application means the opposite of cast in situ. In other words, the pre-cast reinforced concrete frame is finished as finished structures when shipped to a builder or customer, rather than being poured into temporary forms at the building site or place of use.

[0010] As used herein, the term "reinforced concrete" refers to concrete into which reinforcement bars or fibres have been cast to carry tensile loads in order to strengthen a structure that would otherwise be brittle.

[0011] The frame may also be made of metal, wood, or a castable material. It is to be understood that any suitable castable material, such as cement, mortar, concrete, ceramics, thermoset plastics, and thermoplastics can be used for producing the frame.

[0012] In one or more embodiments, the side and/or base panels are made from a reinforced castable material.

[0013] In one or more embodiments, the side and/or base panels are made from a reinforced castable material, and wherein the reinforcement extends beyond the side and/or base panels.

[0014] As used herein, the term "reinforced castable material" refers to a castable material into which reinforcement bars or fibres have been cast to carry tensile loads in order to strengthen a structure that would otherwise be brittle.

[0015] In the present context, the term "lifting anchor" should be broadly construed to encompass any such device for lifting the frame with or without gate members and actuators installed therein. Alternatively, a coupler adapted for receiving a lifting anchor is embedded in the frame. The coupler may comprise internal or external threading, depending on the configuration of the lifting anchor.

[0016] In one or more embodiments, the lifting anchor or coupler adapted for receiving a lifting anchor is mechanically tied into the reinforcing members embedded in the castable material, such as concrete.

[0017] In order to avoid that water will undermine the base panel; it may be an advantage to extend the base panels beyond the side panels, preferably beyond the front, back and outer side/face of the side panel. In one or more embodiments, the base panel extends beyond the side panels.

[0018] In one or more embodiments, the base panel extends beyond the front of the side panels.

[0019] In one or more embodiments, the base panel extends beyond back of the side panels.

[0020] In one or more embodiments, the base panel extends beyond the outer side/face of the side panels.

[0021] In one or more embodiments, the base panel extends beyond the front and/or the back and/or the outer side of the side panels.

[0022] In one or more embodiments, the part of the base panel extending beyond the side panels comprises channels adapted for receiving an earth anchor.

[0023] In one or more embodiments, the reinforcement extends beyond the side and/or base panels.

[0024] In one or more embodiments, the reinforcement extends beyond the side panels, preferably beyond the front and back of the side panel. This will allow the pre-fabricated sluice gate system to be built into other reinforced concrete structures.

[0025] In one or more embodiments, the reinforcement extends beyond the front of the side panels.

[0026] In one or more embodiments, the reinforcement extends beyond the back of the side panels.

[0027] In one or more embodiments, the reinforcement extends beyond the outer side/face of the side panels.

[0028] In one or more embodiments, the reinforcement extends beyond the front and/or the back and/or the outer side of the side panels.

[0029] In one or more embodiments, the one or more channels of a first type and/or of a second type comprises one or more flaps or valves adapted for closing and opening the one or more channels collectively and/or individually.

[0030] In one or more embodiments, the lower gate member comprises a plurality of channels of a first type; wherein each of the channels comprises a flap adapted for closing and opening the one or more channels of a first type, and wherein the flaps are arranged on a single rotating and/or sliding shaft.

[0031] In one or more embodiments, the lower gate member and/or the base panel comprises air and/or water channels adapted to be connected to a source of compressed air and/or water. In one or more embodiments, a part of the base panel is configured as a lower gate member extending between the two side panels. The lower gate member may in one or more embodiments comprise air/water channels adapted to be connected to a source of water and/or compressed air. Water and/or compressed air may thereby be used to remove sediments blocking the function of the one or more gate members.

[0032] In one or more embodiments, the pre-fabricated water control sluice gate system further comprises means for delivering water and/or compressed air.

[0033] In one or more embodiments, the base panel comprises suction channels adapted to be connected to a source of suction. With or without the function of the air/water channels, the suction channels may be used to remove sediments blocking the function of the one or more gate members.

[0034] In one or more embodiments, the base panel comprises one or more channels of a second type extending from one side of the lower gate member to the other side of the lower gate member, and wherein one or more inlets and one or more outlets of a channel is positioned on each side of the lower gate member, and wherein the one or more channels of a second type are configured for being in a closed configuration and in an open configuration.

[0035] In one or more embodiments, each of the channels of a second type comprises a flap adapted for closing and opening the one or more channels, and wherein the flaps are arranged on a single rotating and/or sliding shaft.

[0036] In one or more embodiments, each of the channels of a second type comprises a plurality of channels; wherein each of the channels comprises a flap adapted for closing and opening the one or more channels, and wherein the flaps are arranged on a single rotating and/or sliding shaft.

[0037] In one or more embodiments, the channels of a second type are in liquid communication with one or more suction channels adapted to be connected to a source of suction.

[0038] In one or more embodiments, the channels of a second type are in liquid communication with one or more channels adapted for liquid communication with a reservoir.

[0039] In one or more embodiments, the pre-fabricated sluice gate system further comprises a venturi injector unit positioned downstream to the one or more gate members; wherein the venturi injection unit comprises one or more venturi injectors comprising an input port adapted for receiving a part of the water passing the one or more gate members, an output port, and an injection port; wherein the channels of a second type are in liquid communication with an injection port of one or more venturi injectors. This configuration allows sedimentation to be removed at positions close to the inlets and outlets of the channels of a second type, and the sedimentation is delivered further downstream through the output port(s) of the venturi injector(s).

[0040] In one or more embodiments, the channels of a second type comprise suction channels adapted to be connected to a source of suction.

[0041] In one or more embodiments, the channels of a second type comprise channels adapted for liquid communication with a reservoir.

[0042] In one or more embodiments, the inner side of the side panels each comprises a channel configured for receiving a moving gate member.

[0043] In one or more embodiments, the outer face of the side panels each comprises a channel configured for receiving a reinforcement plate adapted for being imbedded in the adjacent dam section.

[0044] In one or more embodiments, the outer face of the side panels each comprises a channel configured for receiving a reinforcement plate adapted for being imbedded in the adjacent dam section.
