Description
Technical Field
[0001] This invention relates to the field of hydraulic fill, specifically to a hydraulic fill consolidation and drainage structure and a rapid reinforcement method for hydraulic fill. Background Technology
[0002] Hydraulic fill is a type of fill formed by hydraulically filling mud and sand. It is one of the most common types of artificial fill along the coast of my country. It is mainly used for dredging or clearing river channels, or for filling or raising certain sections of the river near the river for industrial and agricultural production. High-pressure mud pumps are used to pump the mud and sand dredged by dredgers through mud conveying pipes to the areas that need to be filled and the mud and sand accumulation areas. The former is a planned and purposeful filling, while the latter is a purposeless accumulation. After sedimentation and drainage, it forms a large layer of hydraulic fill. However, when the existing fill material is very fine, water is difficult to drain. The soil is in a fluid state in the early stage of formation. After the surface evaporates naturally, it often cracks, and the water underneath is not easy to drain. It is in an unconsolidated state and may remain fluid for a long time. With slight disturbance, it will exhibit thixotropy. How to quickly drain and consolidate the fill is an important step in the treatment of fill. However, the existing drainage structure is relatively simple, with low drainage efficiency and low drainage rate. Moreover, the reinforcement speed of fill is slow and the reinforcement effect is poor. Therefore, a consolidation and drainage structure for fill and a method for rapid reinforcement of fill are provided. Summary of the Invention
[0003] The purpose of this invention is to address the deficiencies of the prior art by providing a consolidated drainage structure for dredged fill and a rapid reinforcement method for dredged fill, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a dredged fill consolidation and drainage structure and a rapid dredged fill reinforcement method, comprising a dredged fill layer and a brick slag layer, wherein a brick slag layer is provided between each dredged fill layer, the dredged fill layer is composed of a mixture of mud and gravel, a filter screen is provided at one end of both the dredged fill layer and the brick slag layer, a first water conveying trough is provided on one side of the filter screen, and a second water conveying trough is provided on one side of the brick slag layer, wherein one end of both the first water conveying trough and the second water conveying trough is connected to a drainage trough through a drainage pipe.
[0005] As a preferred embodiment of the present invention, the thickness of the dredged fill layer is 10 times the thickness of the brick slag layer.
[0006] As a preferred embodiment of the present invention, the mixing ratio of the mud and crushed stone is 10:1.
[0007] As a preferred embodiment of the present invention, the first water conveying tank, the second water conveying tank, and the drainage tank are all made of reinforced concrete.
[0008] In a preferred embodiment of the present invention, the mud and crushed stone are in a superimposed structure.
[0009] A method for rapid reinforcement of dredged fill, the specific steps of which are as follows:
[0010] S1: Select a site and then construct the first and second water supply channels and the drainage channel;
[0011] S2: Lay a layer of brick rubble 4 cm thick on the ground where backfill soil needs to be piled.
[0012] S3: Then, the high-pressure mud pump is used to pump the mud and sand dredged by the dredger through the mud conveying pipe to the top of the brick and sand layer that needs to be covered.
[0013] S4: When the thickness of the mud slurry is 10 cm each time, lay a layer of gravel on top of the mud. When the total height of the mud and gravel is 40 cm, lay a layer of brick rubble on top of the mud.
[0014] S5: In this way, the brick slag layer and the second water conveyance channel are on the same horizontal plane, and the dredged fill layer and the first water conveyance channel are on the same horizontal plane.
[0015] S6: As the dredged soil layers are continuously stacked, some of the water in the dredged soil layers enters the first water conveying channel through the filter screen. Under the gravity and compression of the dredged soil layers and the brick rubble layers, the water in the dredged soil layers is squeezed into the first water conveying channel, while some of the water in the dredged soil layers seeps into the brick rubble layers and is transported to the second water conveying channel through the brick rubble layers.
[0016] S7: Water from the first and second water conveyance channels is transported to the drainage channel through the conveying pipeline. The water is then pumped into the river by the suction pump and filter box, thereby quickly reinforcing the dredged fill.
[0017] The beneficial effects of this invention are: the drainage structure of the dredged fill can quickly drain the water in the dredged fill, and the drainage rate is high and the drainage speed is fast. Using brick debris as a water conveyance base layer can quickly convey water, and it can also compress the dredged fill to improve the drainage rate. The reinforcement method of the dredged fill can improve the solidification efficiency of the dredged fill. Mixing the dredged fill with crushed stone increases the gap between the dredged fill mud, which not only improves the overall reinforcement speed of the dredged fill, but also facilitates the drainage of water in the dredged fill, allowing the dredged fill to be rationally reused.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.
[0022] Example: Please refer to Figure 1-2 The present invention provides a technical solution: a dredged fill consolidation and drainage structure and a method for rapid reinforcement of dredged fill, comprising a dredged fill layer 1 and a brick slag layer 2, wherein a brick slag layer 2 is provided between each dredged fill layer 1, the dredged fill layer 1 is composed of a mixture of mud 11 and crushed stone 12, a filter screen plate 4 is provided at one end of both the dredged fill layer 1 and the brick slag layer 2, a first water conveying trough 5 is provided on one side of the filter screen plate 4, and a second water conveying trough 6 is provided on one side of the brick slag layer 2, and one end of both the first water conveying trough 5 and the second water conveying trough 6 is connected to a drainage trough 3 through a drainage pipe.
[0023] The thickness of the dredged fill layer 1 is 10 times the thickness of the brick slag layer 2.
[0024] The mixing ratio of mud 11 and crushed stone 12 is 10:1.
[0025] The first water conveying channel 5, the second water conveying channel 6, and the drainage channel 3 are all made of reinforced concrete.
[0026] The mud material 11 and the crushed stone 12 are in a superimposed structure.
[0027] A method for rapid reinforcement of dredged fill, the specific steps of which are as follows:
[0028] S1: Select a site and then construct the first water conveyance channel 5, the second water conveyance channel 6, and the drainage channel 3;
[0029] S2: Lay a layer of brick rubble 2 on the ground where backfill soil needs to be piled up. The thickness of the brick rubble is 4 cm.
[0030] S3: Then, the dredged mud and sand from the dredger are pumped through a high-pressure mud pump to the top of the brick slag layer 2.
[0031] S4: When the thickness of the mud slurry is 10 cm each time, lay a layer of gravel 12 on top of the mud 11. When the total height of the mud 11 and gravel 12 is 40 cm, lay a layer of brick slag 2 on top of the mud 11.
[0032] S5: In this way, the brick slag layer 2 and the second water conveying channel 6 are on the same horizontal plane, and the dredged fill layer 1 and the first water conveying channel 5 are on the same horizontal plane.
[0033] S6: As the dredged soil layer 1 is continuously stacked, a portion of the water in the dredged soil layer 1 enters the first water conveying tank 5 through the filter screen plate 4. Under the gravity and compression of the dredged soil layer 1 and the brick rubble layer 2, the water in the dredged soil layer 1 is squeezed into the first water conveying tank 5, while a portion of the water in the dredged soil layer 1 seeps into the brick rubble layer 2 and is transported to the second water conveying tank 6 through the brick rubble layer 2.
[0034] S7: Water in the first water conveyance tank 5 and the second water conveyance tank 6 is transported to the drainage tank 3 through the conveying pipeline. The water is then pumped into the river by the suction pump and the filter box, thereby quickly reinforcing the dredged fill.
[0035] The drainage structure of this dredged fill can quickly drain the water from the fill, with a high drainage rate and fast drainage speed. Using brick debris as a water conveyance base layer allows for rapid water conveyance and also compresses the fill, improving its drainage rate. This reinforcement method can improve the solidification efficiency of the fill by mixing it with gravel, increasing the gaps between the fill materials. This not only improves the overall reinforcement speed of the fill but also facilitates the drainage of water, allowing the fill to be reused rationally.
[0036] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
