Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water conservancy construction, in particular to a water conservancy construction waterproof drainage device. BACKGROUND

[0002] The foundation pit water collecting well dewatering method plays a key role in waterproofing and drainage in water conservancy construction, efficiently collecting construction water, rainwater and groundwater. The water collecting well, as the core drainage node, can collect underground water, rainwater and construction wastewater in the foundation pit. The drainage ditch is designed with a slope (usually 0.2% to 0.5%) to ensure efficient water flow into the water collecting well, and the continuous pumping ensures that the foundation pit is free of water, providing a dry environment for excavation, pouring and other operations. The pumping optimizes the working environment. Meanwhile, the gravel filter layer reduces sediment loss and reduces disturbance to the surrounding environment. The equipment is simple and low in cost, and is suitable for shallow dewatering in coarse-grained soil or low-permeability clay layer.

[0003] Chinese patent CN118895779B discloses a water conservancy construction waterproof drainage device.

[0038] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] Example: Initial state as follows Figures 1-16 As shown, a waterproofing and drainage device for water conservancy construction includes a support assembly 4 and a water pump 1 fixed on its top. A treatment box 3 is fixed inside the support assembly 4. A rotating plate 8 is rotatably connected to the inside of the treatment box 3. A separation part 6 is drivenly connected to one end of the rotating plate 8. A filter part 5 is provided inside the treatment box 3. A filter plate 7 is detachably connected to the bottom of the filter part 5. The support assembly 4 includes a base 42, which is fixed to the bottom of the water pump 1. A top frame 43 is fixed to the top of the base 42. A bottom column 41 is fixed to the bottom of the base 42. The treatment box 3 is fixed to the top of the bottom column 41. A drain pipe 9 is fixed to one side of the treatment box 3. The drain pipe 9 is located at the bottom of the base plate 65.

[0040] In this embodiment, the water pump 1 can be set as a KQSN series wear-resistant centrifugal pump, matched with a YKK560-6G motor or other water pump 1 and its matched motor that meet the pumping requirements. This series of water pump 1 is designed for conveying media containing solid particles. The impeller is made of high chromium alloy material with strong wear resistance, which meets the working condition requirements of pumping silt and gravel water. The flow range is 800-2000 m³ / h, and the lift is 20-100 m, which can cover high-load scenarios such as foundation dewatering and river pumping. This is prior art and will not be described in detail. Before using this device, the bottom of the water collection well needs to be paved with a gravel filter layer with a thickness of ≥0.3 m or layered with gravel + coarse sand. The bottom layer is paved with coarse gravel layer (about 0.1 m thick) to intercept large particle silt, and the upper layer is paved with gravel or coarse sand layer (0.2-0.3 m thick) to filter fine particles, preventing large silt and gravel particles from flowing into the well with water during pumping, protecting the water pump 1 impeller from wear and tear, and reducing the risk of well wall collapse. The filter layer extends to the well wall, which can also be reinforced with bamboo and wood to prevent filter loss. Workers use a water pipe to connect the water pump 1 inlet and the water collection well, then connect another water pipe and the drain pipe 9, and then place the other end of the other drain pipe 9 at the designated discharge location or connect it with other pipelines to prepare for the drainage work.

[0041] Specifically, the rotating plate 8 can convert the fixed and continuous impact of the water pumped into the treatment box 3 by the water pump 1 into intermittent and non-fixed point impact; the filter part 5 includes a support plate 51 fixedly connected to the inner side of the treatment box 3, the top of the support plate 51 is connected with a movable plate 52 through an elastic element 56, the bottom of the movable plate 52 is slidingly connected with a moving plate 53, the top of the moving plate 53 is fixedly connected with a scraper 58, under the intermittent and non-fixed point water flow impact, the movable plate 52 cooperates with the elastic element 56 to move vertically while cooperating with the moving plate 53 to drive the scraper 58 to move horizontally to filter impurities and push the impurities to the separation part 6; the separation part 6 includes a transmission rod 61 rotatably connected to the inner side of the treatment box 3 and a discharge plate 62 fixed to the outer side of the transmission rod 61, the transmission rod 61 drives the discharge plate 62 to discharge the impurities out of the inner side of the treatment box 3 by utilizing the rotating force of the rotating plate 8, the distance between the through hole of the movable plate 52 and the scraper 58 shown in the drawing is not as the actual proportion, but only as a schematic diagram, and those skilled in the art can design according to actual needs.

[0045] When the elastic member 56 releases the elastic force, the movable plate 52 moves to the side away from the bottom of the treatment box 3, the impurities on the top of the movable plate 52 move to the side away from the bottom of the treatment box 3 under the action of water, the movable plate 52 drives the limiting plate 55 to move to the side away from the bottom of the treatment box 3, the inclined slot in the limiting plate 55 extrudes the limiting column 54 to make the moving plate 53 move to the side away from the discharge plate 62, and the moving plate 53 drives the scraper 58 on the top thereof to move to the side away from the discharge plate 62, so that the scraper 58, the movable plate 52 and the moving plate 53 return to the original positions.

[0046] Under the continuous impact of the pulsating water flow, the movable plate 52 repeatedly vibrates to not only push the impurities to the inside of the discharge plate 62, but also avoid the impurities from being accumulated on the top of the movable plate 52 to cause blockage.
