Description

Technical Field

[0001] This utility model relates to the field of geotextile tube technology, specifically to an assembled geotextile tube. Background Technology

[0002] In recent years, my country's transportation infrastructure construction has made significant progress. Large amounts of silt or mud are generated during projects such as river dredging, ditch and pond clearing, and pile foundation excavation. This silt and mud are suspensions containing a certain amount of fine soil particles, possessing a certain viscosity, and requiring prolonged settling to allow for stratification. Currently, mud treatment methods mainly include sedimentation and air drying in mud ponds, transporting mud to designated locations by tanker trucks, and mechanical pressing. These methods suffer from high costs, low efficiency, easy spillage, environmental pollution, safety hazards, and difficulties in subsequent land restoration. Traditional mud treatment methods are increasingly unable to meet the needs of modern transportation construction, necessitating the search for efficient, low-cost, and environmentally friendly treatment methods. Using flocculants in conjunction with geotextile bag filtration for dewatering represents a promising direction for the rapid dewatering, solidification, and volume reduction of silt and mud. Due to the high pressure during the filling of silt and mud, the requirements for geotextile bags are high. Geotextile bags are made of high-strength geosynthetic materials, but in engineering projects, they are often only usable once. This makes the purchase cost of geotextile bags a major component of the cost of using this method to treat silt and mud. If geotextile bags could be reused, it would not only save social resources and significantly reduce the cost of treating silt and mud using this method, but also improve the competitiveness of enterprises. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an assembled geotextile bag, which solves the problems raised in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An assembled geotextile bag includes a top fabric, an upper fixing seat, and a lower fixing seat. A bottom fabric is provided below the top fabric, and a filling head is provided at the top of the top fabric. The top fabric and the bottom fabric are sewn together along one side edge. Upper fixing seats are provided on the remaining sides of the top fabric, and lower fixing seats are provided on the remaining sides of the bottom fabric. A locking plate is provided at the bottom of the upper fixing seat, and a toothed strip is provided at the bottom of the locking plate. First magnetic blocks are provided on both side walls of the locking plate. A slot is formed at the top of the lower fixing seat, and second magnetic blocks are provided on both inner walls of the slot. The first and second magnetic blocks have opposite magnetic properties. A toothed groove is formed at the bottom inner end of the lower fixing seat corresponding to the toothed strip.

[0006] Preferably, the top fabric and the bottom fabric have the same structure. The bottom fabric adopts an inner and outer layer composite structure, consisting of an outer layer of polypropylene woven fabric and an inner layer of water-permeable nonwoven fabric. The inner side of the water-permeable nonwoven fabric is coated with a hydrophobic coating.

[0007] Preferably, the hydrophobic coating is a fluoride superhydrophobic coating.

[0008] Preferably, the interior of the base fabric is provided with vertical and horizontal dividing strips, and the "skeleton" structure formed by the vertical and horizontal dividing strips divides the interior of the base fabric into multiple chambers. Both the vertical and horizontal dividing strips are made of water-permeable material.

[0009] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0010] The assembled geotextile bag provided by this utility model adopts an assembled structure, which is connected by the cooperation of an upper fixing seat, a clamping plate, a first magnetic block, a lower fixing seat, a clamping groove, and a second magnetic block. This greatly improves the strength of the connection and effectively avoids the risk of cracking along the joint during mud filling. By setting a sharp toothed strip at the bottom of the clamping plate and opening a toothed groove at the top of the inner part of the lower fixing seat, the connection strength between the clamping plate and the clamping groove is increased through the mutual meshing of the sharp toothed strip and the toothed groove, thereby improving the fixing stability of the upper and lower fixing seats. At the same time, after the mud inside the geotextile bag is dewatered, the upper fixing seat can be pulled to separate the top and bottom fabrics. After cleaning, the geotextile bag can be reused, thereby improving the reuse rate of the geotextile bag and reducing construction costs.

[0011] This invention features identical top and bottom fabric structures, both employing an inner and outer layer composite structure. The outer layer is composed of a polypropylene woven fabric, and the inner layer is a permeable nonwoven fabric. The polypropylene woven fabric enhances the geotextile bag's tear and impact resistance and protects the inner permeable nonwoven fabric from external loads or construction machinery. The permeable nonwoven fabric forms a uniform pore structure through fiber gaps, rapidly draining free water from the mud while trapping fine particles (particle size > 0.075 mm) to prevent clogging of drainage channels and improve dewatering efficiency. Furthermore, a hydrophobic coating, a fluoride superhydrophobic coating, is applied to the inner side of the permeable fabric to prevent sludge from clogging the permeable pores on the top and bottom fabric surfaces during dewatering, thus affecting dewatering efficiency.

[0012] This invention uses a "skeleton" structure formed by vertical and horizontal dividing strips to divide the interior of the base fabric into multiple chambers. By dispersing the pressure on the mud inside the geotextile bag, the compressive strength of the geotextile bag is greatly improved, and the risk of rupture due to uneven local stress is reduced.

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0020] According to an embodiment of the present invention, an assembled geotextile bag is provided.

[0021] Example 1:

[0022] As shown in the attached diagram of the instruction manual. Figure 1 As shown, an assembled geotextile bag includes a top fabric 1, an upper fixing seat 4, and a lower fixing seat 8. A bottom fabric 2 is provided below the top fabric 1, and a filling head 3 is provided at the top of the top fabric 1. The top fabric 1 and the bottom fabric 2 are sewn together on one side. The remaining sides of the top fabric 1 are provided with upper fixing seats 4, and the remaining sides of the bottom fabric 2 are provided with lower fixing seats 8. A retaining plate 5 is provided at the bottom of the upper fixing seat 4, and a toothed rack 6 is provided at the bottom of the retaining plate 5. First magnetic blocks 7 are provided on both side walls of the retaining plate 5. A slot 9 is provided at the top of the lower fixing seat 8, and second magnetic blocks 11 are provided on both inner walls of the slot 9. The first magnetic blocks 7 and the second magnetic blocks 11 have opposite magnetic properties. A toothed groove 10 is provided at the inner bottom of the lower fixing seat 8 corresponding to the toothed rack 6.

[0023] Example 2:

[0024] As shown in the attached diagram of the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an assembled geotextile bag adopts an assembled structure, which is connected by the cooperation of an upper fixing seat 4, a clamping plate 5, a first magnetic block 7, a lower fixing seat 8, a clamping groove 9, and a second magnetic block 11, greatly improving the strength of the connection and effectively avoiding the risk of cracking along the joint during mud filling. In use, the operator presses down on the upper fixing seat 4, causing the clamping plate 5 to insert into the clamping groove 9. The first magnetic block 7 and the second magnetic block 11 are tightly attracted. Simultaneously, a toothed strip 6 is provided at the bottom of the clamping plate 5, and a toothed groove 10 is formed at the top of the lower fixing seat 8. The interlocking of the toothed strip 6 and the toothed groove 10 increases the connection strength between the clamping plate 5 and the clamping groove 9, thus significantly improving the fixing stability of the upper fixing seat 4 and the lower fixing seat 8. After the mud in the geotextile bag has been dewatered, the upper fixing seat 4 can be pulled upwards to separate the top cloth 1 and the bottom cloth 2. After cleaning, the geotextile bag can be reused, thereby increasing the reusability of the geotextile bag and reducing the cost of using mud flocculation technology.

[0025] The top fabric 1 and bottom fabric 2 are designed with identical structures, both employing an inner and outer layer composite structure. The outer layer consists of a polypropylene woven fabric 2.1 and an inner layer of permeable nonwoven fabric 2.2. The polypropylene woven fabric 2.1 can improve the tear resistance and impact resistance of the geotextile bag and protect the inner permeable nonwoven fabric 2.2 from damage caused by external loads or construction machinery. The permeable nonwoven fabric 2.2, through the uniform pore structure formed by the fiber gaps, can quickly drain free water from the mud while retaining fine particles (particle size > 0.075 mm), preventing blockage of drainage channels and improving dewatering efficiency.

[0026] The inner side of the permeable textile fabric 2.2 is coated with a hydrophobic coating 2.3, which is a fluoride superhydrophobic coating. This coating can prevent sludge from clogging the permeable pores on the surface of the top fabric 1 and the bottom fabric 2 during the dewatering process, thus affecting the dewatering efficiency. The fluoride superhydrophobic coating has excellent hydrophobic properties, which can more effectively prevent sludge from clogging the permeable pores and ensure stable dewatering efficiency.

[0027] The "skeleton" structure formed by the vertical dividing strips 12 and the horizontal dividing strips 13 divides the interior of the bottom fabric 2 into multiple chambers, thereby dispersing the pressure of the mud inside the geotextile bag, which greatly improves the compressive strength of the geotextile bag and reduces the risk of rupture due to uneven local stress.
