Description

Technical Field

[0001] This utility model relates to the field of geotextile bag construction technology, and in particular to an underwater geotextile bag laying and fixing device. Background Technology

[0002] Formwork concrete is produced by using a high-pressure pump to inject concrete or cement mortar into formwork bags. After the concrete or cement mortar solidifies, it forms a plate-like or other structure with a certain strength. This structure is then laid on a slope. The maximum allowable slope on the embankment is 1:1, which is a 45° slope, thus meeting the needs of the project.

[0003] Currently, in traditional underwater geotextile construction, steel stakes or wooden piles are typically driven into the top of the slope as anchors before the geotextile is fully extended and submerged in the water. The geotextile is laid from top to bottom, with sandbags at the bottom for fixation. However, without considering the influence of water flow, the sandbags cannot be firmly secured, and the geotextile floats due to the current. This prevents the underwater portion of the geotextile from adhering tightly to the slope, which is detrimental to the slope protection effect after the geotextile concrete has solidified and also hinders the positioning and formation of the slope toe. Therefore, to improve the underwater geotextile laying effect and construction quality, and to advance industry technology and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from existing underwater geotextile laying and fixing devices and application methods. Utility Model Content

[0004] The purpose of this invention is to solve the problems that existing sandbags cannot be pressed and fixed, and the formwork bags float up due to the influence of water flow during installation, which cannot ensure that the underwater part of the formwork bag is in close contact with the slope surface and is not conducive to the slope protection effect after the formwork bag concrete is formed. Therefore, an underwater formwork bag laying and fixing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An underwater geotextile bag laying and fixing device includes a geotextile bag body. One end of the geotextile bag body is fixedly connected to multiple connecting cloth strips, which are cylindrical in structure. A counterweight bag is fixedly connected between the multiple connecting cloth strips. The counterweight bag is filled with a filling layer. A central shaft is inserted into the counterweight bag. Multiple through shafts are fixedly connected to the outer wall of the central shaft. The other end of the through shaft passes through the counterweight bag. The other end of the geotextile bag body is snapped with multiple insertion rings, and anchor piles are inserted into the insertion rings.

[0007] Furthermore, one end of the intersecting shaft has a tapered structure.

[0008] Furthermore, one end of the molded bag body is provided with multiple injection ports.

[0009] Furthermore, a footboard is fixedly connected to the top of the two anchor piles, and the outer wall of the footboard is provided with anti-slip grooves.

[0010] Furthermore, the outer wall of the anchor pile is fitted with a rubber sleeve.

[0011] Furthermore, the bottom end of the anchor pile is fixedly connected with two barbs.

[0012] Furthermore, the filling layer is one of the following: a sand layer, a stone layer, or a concrete slag layer.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By fixing the bottom of the formwork bag body under the gravity of the filling layer inside the counterweight bag, the underwater part of the formwork bag body is kept close to the slope surface, which improves the slope protection effect after the formwork bag concrete is formed, and also facilitates the positioning and forming of the slope toe.

[0015] 2. The anchor pile is equipped with two barbs, which prevents the anchor pile from detaching from the soil and improves the anchor pile's fixing effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 An underwater geotextile bag laying and fixing device includes a geotextile bag body 1. One end of the geotextile bag body 1 is sewn with multiple connecting cloth strips 2. The connecting cloth strips 2 are cylindrical structures. The multiple connecting cloth strips 2 are sewn together with counterweight bags 3. The counterweight bags 3 are filled with a filling layer 6. A central shaft 4 is inserted into the counterweight bags 3. Multiple through shafts 5 are welded to the outer wall of the central shaft 4. The other end of the through shafts 5 passes through the counterweight bags 3. The counterweight bags 3 fall into a ditch dug at the bottom of the slope, so that the through shafts 5 are inserted into the sludge. The depth of the ditch is 1.5-3 times the height of the counterweight bags 3.

[0025] When making the counterweight bag 3, take a rectangular piece of fabric and make multiple mounting holes for the intersecting shafts 5 on the fabric surface. Overlock the edges around the mounting holes to prevent tearing. Then, wrap the rectangular fabric around the central shaft 4 so that the intersecting shafts 5 are inserted. Then sew the joints together and the bottom together. Start filling the bag to form the filling layer 6. Finally, sew on the cap. The filling material is selected according to the actual water flow. Choose a material whose weight is greater than the water flow speed to prevent it from being washed away by the water flow.

[0026] The bottom end of the mold bag body 1 is fixed under the weight of the filling layer 6 inside the counterweight bag 3 to ensure that the underwater part of the mold bag body 1 is in close contact with the slope surface, and the slope of the slope surface is less than 45°.

[0027] The other end of the plastic bag body 1 is fitted with multiple insertion rings 8, and anchor piles 9 are inserted into the insertion rings 8. The anchor piles 9 are driven into the soil, thereby fixing one end of the plastic bag body 1 to the top of the slope.

[0028] One end of the intersecting shaft 5 has a tapered structure.

[0029] The mold bag body 1 has multiple injection ports 7 at one end, and the filling mortar is injected into the mold bag body 1 through the injection ports 7.

[0030] A foot pedal 12 is welded to the top of the two anchor piles 9. The outer wall of the foot pedal 12 is provided with anti-slip grooves. Stepping on the foot pedal 12 makes it easier for the anchor pile 9 to penetrate into the soil.

[0031] A rubber sleeve 10 is fitted onto the outer wall of the anchor pile 9 to facilitate manual operation of the anchor pile 9.

[0032] Two barbs 11 are welded to the bottom of the anchor pile 9. The barbs 11 prevent the anchor pile 9 from detaching from the soil.

[0033] The filling layer 6 is one of the following: sand layer, stone layer, or concrete slag layer.

[0034] The working principle of this embodiment is as follows: In use, firstly, step on the pedal 12 or press down with your hand to drive the anchor pile 9 into the soil, thereby fixing one end of the formwork bag body 1 to the top of the slope. The barbs 11 prevent the anchor pile 9 from detaching from the soil. Then, under the weight of the counterweight bag 3 and the filling layer 6, the other end of the formwork bag body 1 rolls down the slope, thus laying the formwork bag body 1 on the slope. At this time, the counterweight bag 3 falls into the trench dug at the bottom of the slope. Under the weight of the filling layer 6 inside the counterweight bag 3, the bottom end of the formwork bag body 1 is fixed to ensure that the underwater part of the formwork bag body 1 is in close contact with the slope. Then, the filling mortar is injected into the formwork bag body 1 from the injection port 7, and waits for it to form, thus achieving the slope protection effect.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
