Description

Technical Field

[0001] This utility model relates to an eco-friendly mud-filling tube bag suitable for use in silty tidal flats with locally sourced materials. Background Technology

[0002] Traditional filling bags are mainly divided into sand-filled bags and mud-filled bags, but both types face significant limitations, failing to meet the needs of sustainable development in terms of filler material acquisition, construction efficiency, and environmental compatibility. Sand-filled bags rely excessively on sand sources, resulting in high costs for purchasing sand. Restrictions imposed by sand mining permits, transportation distances, and ecological red lines further exacerbate the economic and ecological costs. Mud-filled bags use shallow, recently deposited soil as filling material, typically adding solidifying agents or dehydrating agents to improve soil properties. However, problems remain: high proportions of solidifying agents lead to high costs and poor economic efficiency, and high dosages can easily cause soil hardening and embrittlement; dehydrating agents have limited solid-liquid separation effects on silty soils and low consolidation efficiency.

[0003] In ecologically fragile and sensitive areas such as the Yangtze River estuary and coastal wetlands, construction must take into account environmental protection requirements. Traditional techniques struggle to achieve on-site soil sourcing, overcome reliance on sand sources, ensure thorough solid-liquid separation, achieve efficient consolidation, meet requirements for heavy metal locking, and prevent secondary mudification. Therefore, there is an urgent need for an efficient, economical, and environmentally friendly mud-filled pipe bag to overcome the technical bottlenecks of traditional cofferdam construction and achieve a dual improvement in economic and ecological benefits. Utility Model Content

[0004] In view of the above-mentioned problems of the prior art, this utility model is proposed, which can effectively solve the above-mentioned problems of the prior art.

[0005] This utility model solves the above problems through the following technical solution:

[0006] An eco-friendly mud-filled tube bag suitable for use in silty mudflats with locally sourced materials includes: a mud pumping system, a dehydrating agent preparation system, a solid-liquid separation system, and a geotextile tube bag system; wherein: the mud pumping system is connected to the solid-liquid separation system via a mud conveying pipeline; the dehydrating agent preparation system is connected to the mud conveying pipeline via a reagent delivery pipeline to provide dehydrating agent to the solid-liquid separation system; and the solid-liquid separation system is connected to the geotextile tube bag system via a filling pipe.

[0007] Preferably, the mud pumping system includes a mud pump and a control valve, wherein the inlet of the mud pump is connected to an inlet pipe, and the control valve is located at the mud delivery pipe inlet connected to the mud pump.

[0008] Preferably, the dehydrating agent preparation system includes a reagent pump, a reagent delivery pipeline, and a water supply pipeline, wherein the water supply pipeline is connected to the reagent pump, and the reagent pump is connected to the reagent delivery pipeline.

[0009] Preferably, the solid-liquid separation system includes a filling main pipe and an observation port, with the observation port located on the filling main pipe at a distance of approximately 100-200 meters from the mixing node of the mud and dewatering agent.

[0010] Preferably, the geotextile tube system is a place for the sedimentation, dehydration and consolidation of mud after solid-liquid separation treatment. It can be connected to the filling main pipe of the solid-liquid separation system through the sleeve on the geotextile tube. Multiple filling main pipes can also be set according to the actual situation.

[0011] By adopting the above technical solution, the soil material of this utility model can be sourced locally without relying on sand sources, thus reducing economic costs and achieving high cost-effectiveness. The soil material is fully combined with the dewatering agent, and the silt consolidation status is monitored in real time through a solid-liquid separation system, allowing for timely adjustment of slurry flow and dewatering agent concentration to improve consolidation efficiency and ensure solid-liquid separation effect. The use of tidal flat soil material on-site avoids the need to transport filler material from outside, reducing environmental disturbance and achieving the requirements of no pollution of residual water and prevention of secondary mudification.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0013] The present invention will now be described in detail with reference to specific embodiments.

[0014] See Figure 1 This is a schematic diagram of the structure of the present invention. The present invention relates to an eco-friendly mud-filled tube bag system suitable for use in silty mudflats, comprising: a mud pumping system 1, a dehydrating agent preparation system 2, a solid-liquid separation system 3, and a geotextile tube bag system 4. The mud pumping system 1 is connected to the solid-liquid separation system 3 via a mud conveying pipeline 13; the dehydrating agent preparation system 2 is connected to the mud conveying pipeline 13 via a chemical delivery pipeline 23 to provide dehydrating agent to the solid-liquid separation system 3; the solid-liquid separation system 3 is connected to the geotextile tube bag system 4.

[0015] See Figure 1As shown, the mud pumping system 1 includes a mud pump 11, a control valve 12, and a mud conveying pipeline 13. The inlet of the mud pump 11 is connected to an inlet pipe, and the control valve 12 is located at the mud conveying pipeline inlet connected to the mud pump 11. The dewatering agent preparation system 2 includes a chemical pump 21, a water supply pipeline 22, and a chemical pumping pipeline 23. The water supply pipeline 22 is connected to the chemical pump 21, and the chemical pump 21 is connected to the chemical delivery pipeline 23. The solid-liquid separation system 3 includes a filling main pipe 32 and an observation port 31. The observation port 31 is located on the filling main pipe 32, approximately 100-200 meters away from the mixing node of the mud and dewatering agent. The filling main pipe 32 is connected to the geotextile bag system 4. The geotextile bag system 4 is the site for sedimentation, dewatering, and consolidation of the mud after solid-liquid separation treatment. It can be connected to the filling main pipe 32 through the sleeve on the geotextile bag, or multiple filling main pipes can be set up according to the actual situation.

[0016] The specific construction process is as follows:

[0017] 1) Based on the design requirements and process needs, a mud pumping system 1, a dewatering aid preparation system 2, a solid-liquid separation system 3, and a geotextile bag system 4 are installed.

[0018] 2) Remove surface debris from the soil extraction area, pump mud using mud pump 11, and pump the mud to the solid-liquid separation system 3 via mud conveying pipeline 13. The mud pumping flow rate is controlled by control valve 12.

[0019] 3) Use water supply pipe 22 to deliver clean water to the reagent mixing tank, slowly and evenly add the dehydrating agent and dissolve it completely, and then pump it to the solid-liquid separation system 3 through reagent pumping pipe 23.

[0020] 4) During the filling process, observe the reaction effect of mud and dehydrating agent solution in real time through observation port 31, check whether the mud flocculates quickly and settles in layers. If the mud is not fully flocculated and separated, adjust control valve 12 to control the mud pump flow rate or manually adjust the amount of dehydrating agent to control the concentration of dehydrating agent until the mud flocculation state meets the construction requirements. At the same time, check the reaction at observation port 31 according to the amount of dehydrating agent delivered or in combination with the drainage effect of geotextile bag system 4 to ensure the solid-liquid separation effect.

[0021] 5) After solid-liquid separation, the mud is transported to the geotextile bag system 4 through the filling pipe 32. During filling, a "filling → filtration → refilling" cycle process is adopted. After each filling of the geotextile bag, the solid and liquid layers are separated and the clear water is discharged. Then, the bag can be compacted by stepping on it manually to further drain the water inside the bag. After consolidation, it is refilled to ensure layered consolidation.

[0022] This invention innovatively combines silty soil with an environmentally friendly dewatering agent to optimize the construction process of mud-filled geotextile bags, significantly improving the construction efficiency and environmental performance of cofferdams. The soil used in the geotextile bags is sourced locally, eliminating reliance on sand sources and reducing costs. The combination of silty soil and the environmentally friendly dewatering agent shortens soil consolidation time, improves consolidation efficiency, and reduces the construction cycle. Combined with the geotextile bag structure, a temporary cofferdam is constructed, with an average density of ≥14.5 KN / m³, providing excellent resistance to wind and waves. Excess water is pollution-free, minimizing its impact on the ecological environment. This invention is suitable for cofferdam projects in ecologically sensitive areas and under complex geological conditions, and has broad application value.

[0023] The beneficial effects of this utility model are: the soil material of this utility model can be obtained from nearby soil sources and does not rely on sand sources, thus reducing economic costs and achieving high cost performance; the soil material and dewatering agent are fully combined, and the silt consolidation status is monitored in real time through a solid-liquid separation system, allowing for timely adjustment of slurry flow and dewatering agent concentration to improve consolidation efficiency and ensure solid-liquid separation effect; the use of tidal flat soil material on-site avoids the need to transport filler material from outside, reducing environmental disturbance and achieving the requirements of no pollution of residual water and prevention of secondary mudification.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
