Description
Technical Field
[0001] The utility model belongs to the technical field of water conservancy construction, in particular to a channel bottom segmented silt removal and interception device. Background Art
[0002] Ditches are important channel structures in water conservancy projects, mainly used for water transportation, water diversion for power generation, agricultural irrigation, etc. After long-term use, debris and silt are deposited at the bottom of the ditch, resulting in a reduction in the flow area of the ditch, affecting water conservancy irrigation, flood control and drainage, etc. Ditch bottom dredging is an important part of water conservancy construction.
[0003] Dry dredging is a method of dredging by lowering the water level in the ditch or completely draining the ditch, which facilitates the cleaning of sediments at the bottom of the ditch. When using the dry dredging method to dredge the ditch to be dredged, the ditch to be dredged is divided into multiple sections and processed in sequence. When dredging each section of the ditch, a temporary cofferdam is built in the ditch to block water and intercept flow, so as to achieve the purpose of lowering the water level in the ditch downstream of the cofferdam or draining the water in the downstream ditch.
[0004] Common types of cofferdams include earth and stone cofferdams, concrete cofferdams, grass and soil cofferdams, wooden cage cofferdams, steel sheet pile lattice cofferdams, etc. Among them, it is advisable to build temporary cofferdams in ditches to block water and intercept flow, which is convenient for disassembly and assembly, low cost, and can be reused. In the existing technology, sandbags or bricks and stones are often used to build temporary cofferdams for ditch dredging, which has good water blocking and interception effects and low costs. However, due to the segmented interception and dredging of ditches, the use of sandbags or bricks and stones to build temporary cofferdams is not convenient for disassembly and assembly and reuse. Utility Model Content
[0005] The purpose of the utility model is to provide a channel bottom segmented silt removal and interception device to solve the above technical problems.
[0006] The utility model is realized by the following technical solutions:
[0007] A channel bottom segmented desilting and intercepting device comprises a plurality of L-shaped vertical baffles, which are arranged and installed along the flow cross section in the ditch to block water and intercept flow, and the rear side wall of each L-shaped vertical baffle is fixed with two L-shaped groove plates, and the two L-shaped groove plates respectively form U-shaped slots extending in the vertical direction with the two ends of the L-shaped vertical baffle;
[0008] It includes a plurality of facade plug-ins, and the facade plug-ins can be inserted into the U-shaped card slot; when a plurality of L-shaped facade baffles are arranged and installed along the flow section of the ditch for blocking water and intercepting flow, the left end and the right end of the facade plug-in plate can be respectively inserted into the two U-shaped card slots between two adjacent L-shaped facade baffles. When two adjacent L-shaped facade baffles are closely together, the facade plug-in plate is inserted behind the two to improve the stability between the two L-shaped facade baffles. Due to the limitation of the width of the ditch, the arrangement and installation of a plurality of L-shaped facade baffles cannot completely block the entire flow section. When there is a gap between two adjacent L-shaped facade baffles, the facade plug-in plate is inserted behind the two to not only improve the stability between the two L-shaped facade baffles, but also block the gap between the two L-shaped facade baffles, thereby forming a blockage in the flow section of the ditch;
[0009] It includes two L-shaped side baffles. When the two side walls of the ditch are inclined, multiple L-shaped vertical baffles are arranged and installed along the flow cross section and cannot form a complete blockage. There is a gap between the two side walls of the ditch and the L-shaped vertical baffles. One side of the L-shaped side baffle can be attached to the side wall of the ditch, and the other side can be attached to the front side wall of the L-shaped vertical baffle. In this way, the L-shaped side baffle can be used to block the gap between the side wall of the ditch and the L-shaped vertical baffle, so that the multiple L-shaped vertical baffles, the multiple vertical plug plates and the two L-shaped groove plates form a baffle wall to form a blockage in the flow cross section of the ditch.
[0010] It also includes a number of sandbags and a number of hanging nets; when constructing a temporary cofferdam to block water and intercept flow, a number of L-shaped vertical baffles, a number of vertical plug plates and two L-shaped groove plates form a baffle wall to form a blockage in the flow section of the ditch, and a number of sandbags can be stacked on the front side of the baffle wall to form a sandbag retaining wall, which can prevent the baffle wall from being washed away by water and ensure the stability of the intercepting device; when stacking sandbags on the front side of the baffle wall, a layer of hanging nets is first laid on the inner bottom surface of the L-shaped vertical baffle, and then a layer of sandbags is laid on the hanging nets, and the hanging nets and sandbags are laid alternately in this way. When dismantling the intercepting device, the hanging nets are gathered to wrap the upper sandbags, and the hanging nets and sandbags can be lifted layer by layer using lifting equipment (such as an excavator or a crane), which is convenient for quickly removing the sandbags. After the intercepting device is dismantled, it can be installed and used again at another water blocking and intercepting point.
[0011] Furthermore, a plurality of insert rods are welded on the bottom surface of each L-shaped vertical baffle, and the bottom end of the insert rod is in a pointed cone shape; when a plurality of L-shaped vertical baffles are arranged and installed along the flow cross-section in the ditch, the insert rods can be inserted into the bottom of the ditch, and the bottom surface of the L-shaped vertical baffle is embedded in the bottom of the ditch, thereby fixing the L-shaped vertical baffle, which can improve the stability of the L-shaped vertical baffle.
[0012] Furthermore, a front baffle is fixedly provided at the bottom front end of each L-shaped vertical baffle, and a U-shaped groove is formed between the bottom of the L-shaped vertical baffle and the front baffle. The hanging net and sandbags are laid in the U-shaped groove, which can improve the stability of the sandbag wall.

[0014] Furthermore, each of the L-shaped side baffles is provided with a socket for inserting an anchor nail; when the side of the L-shaped side baffle is attached to the side wall of the ditch, the anchor nail can be used to anchor the L-shaped side baffle to the side wall of the ditch, which can improve the stability of the L-shaped side baffle, and the other side wall of the L-shaped side baffle can also form a barrier on the front side of the L-shaped vertical baffle, thereby improving the stability of the L-shaped vertical baffle.
[0015] Furthermore, a cone plate is fixedly provided at the bottom of each of the facade plug plates, and the cone plate can be inserted into the bottom of the ditch to improve the stability of the facade plug plates.
[0016] Furthermore, the L-shaped facade baffle, L-shaped groove plate, facade plug plate and L-shaped side baffle are all made of plastic, stainless steel or aluminum alloy.

Sandbags are constructed in front of the baffle wall to improve the stability of the sandbag wall. The sandbag wall is located on the backwater side, which can reduce the pollution of sandbags by sludge at the bottom of the channel and facilitate the recycling of sandbags. When dismantling the intercepting device, the hanging net is gathered to wrap the upper sandbags. The hanging net and sandbags can be lifted layer by layer using lifting equipment (such as excavators and cranes). Multiple sandbags can be lifted at one time, which is convenient for rapid removal of the sandbag wall. After the intercepting device is dismantled, it can be installed and used again at another water blocking and intercepting point in the next section of the ditch.
