Technical Field

[0001] The invention relates to the technical field of geotube dehydration, and in particular to a small geotube which has the functions of accelerating drainage and being recyclable. Background Art

[0002] Geotube dewatering is a mud dewatering technology that injects dredged mud from rivers, lakes and reservoirs into geotubes made of special geotextiles. The solid particles are trapped in the geotubes through the pressure of the contraction of the geotubes, and the clean water is discharged to achieve solid-liquid separation. This technology has been widely used in dredged mud dewatering projects.

[0003] In actual projects, the width of geotube bags is tens of meters, the length can reach hundreds of meters, and the filling height can reach 2.5m. As a result, due to the large volume of the bag, there is a risk of bag rolling during the filling process, and the internal dehydration is poor in the later stage, and the dehydration cycle is long. There are many problems, such as: low site utilization, inability to recycle, difficult transportation, poor dehydration efficiency and other issues. Summary of the invention

[0032] The base fabric 1, the top fabric 2 and the side wall fabric 3 are all woven from high-tenacity polypropylene yarns.

[0033] A zipper 31 is sewn on the outer surface of the side wall cloth 3. The area enclosed by a single zipper 31 accounts for 25% of the outer surface area of ​​the side wall cloth 3. The zipper 31 is used to connect with adjacent geotube bag units. The geotube bag group formed by the zipper connection is arranged in a line.

[0034] A mud inlet cuff 22 is provided in the middle of the top cloth 2, and the mud inlet cuff is used to receive the mud to be processed;

[0035] A plurality of drain pipe cuff pairs 5 are arranged at corresponding positions on the upper surface of the base fabric and the lower surface of the top fabric. Both ends of the drain pipe 4 are clamped with corresponding ends of the drain pipe cuff pairs through clamps. The spacing between adjacent drain pipe cuff pairs 5 is 0.3 to 0.5 m.

[0036] The drainage pipe 4 is a corrugated pipe with a needle-punched non-woven fabric sleeved thereon. A through hole is provided at the groove of the corrugated pipe to accelerate drainage. The aperture of the through hole is 1 to 3 mm. Figure 3 shown.

[0037] A lifting belt 11 is sewn on the bottom surface of the base fabric 1, and both ends of the lifting belt 11 extend out of the bottom surface of the base fabric. The lifting belt is used to lift the geotube bag to the vicinity of the transport vehicle under the action of a crane for bottom mud cleaning.

[0038] by Figure 2 Taking the geotube group shown as an example, the following steps are used to perform mud drainage work:

[0039] S1, four geotextile tube bags assembled with drainage pipes are connected by zippers on a pebble cushion with good drainage properties to form a geotextile tube bag group. From left to right, they are the first to the fourth geotextile tube bags.

[0040] S2, close the top cloth zipper, and start filling the mud from the mud inlet cuff of the top cloth of the first geotube bag. At the same time, the geotube bag starts to drain and consolidate;

[0041] S3, after the mud in the first to fourth geotube bags is filled to a height of 1.5 to 2.5 m, the filling is stopped and static settlement begins.

[0042] S4, after a period of time, when the mud in the bag body of the first geotube bag is solidified, the zipper between the first geotube bag and the second geotube bag is opened, and the first geotube bag is hoisted to the vicinity of the transport vehicle by a crane and a lifting belt. At the same time, a new geotube bag is replaced at the original first geotube bag and filled with mud.

[0043] S5, unzip the top cloth of the first geotube bag, dig out the internal consolidated mud, clean it, and wait for reuse.

[0044] S6, after the solidification of the slurry in other geotube bags is completed, the methods of steps S4 and S5 are used to treat them, so as to realize the recycling of the geotube bags.

[0045] like Figure 4 As shown, the combined zipper includes a pair of zipper assemblies, which are respectively arranged at the joints of two adjacent geotube bags; the zipper assembly includes a fixing belt 311, a chain tooth 312 and a zipper head 313, and the fixing belt 311 is sewn between the seams of the bottom cloth, the top cloth and the side wall cloth to increase the connection strength of the combined zipper between adjacent geotube bags.

[0046] The combined zipper 31 has a locking function. The paired zipper heads 313 are each provided with a fixed insertion hole. After the paired zipper heads 313 are pulled to one place, the locking function of the combined zipper is realized by inserting a locking pin into the fixed insertion hole of the paired zipper heads 313.

[0047] The base fabric, top fabric, side wall fabric and zipper edge fabric are all sewn together with polyester fiber thread, and the weight that the polyester fiber thread can bear is 10 to 15 tons.

[0048] The drainage corrugated pipe is made of high-density polyethylene, with a pipe diameter range of 500mm, 600mm or 800mm. The diameter of the drainage pipe cuff is greater than or equal to 800mm, and the geotextile tube bag set includes 4 to 5 geotextile tube bags.

[0049] In order to facilitate the digging of the bottom mud, the lifting belt 11 has different lengths on both sides of the geotextile tube bag base fabric, and the lifting belt on the side facing the C-shaped notch of the C-shaped top cloth zipper is longer. The length ratio of the lifting belt extending from both sides of the base fabric is 2:1, and the length of the shorter end of the lifting belt extending is greater than or equal to half of the width of the geotextile tube bag. The width of the geotextile tube is the side length of the side of the base fabric parallel to the lifting belt.

[0050] In other embodiments of the present invention, the zipper is replaced with a number of vertically arranged metal rings. When multiple geotube bags are connected, U-locks are used to connect the metal rings at corresponding positions to ensure stability during the filling process of the geotube bags without affecting the drainage effect of the side walls between adjacent geotube bags.
