Description

Technical Field

[0001] The present application relates to the technical field of cofferdam slope protection, and specifically to a large sand-filled tube bag slope protection structure. Background Technique

[0002] A cofferdam refers to an enclosure structure constructed using materials such as earth and stone, concrete, etc. in environments such as waters or wetlands, mainly for purposes such as controlling water levels, protecting projects, draining water, storing water, etc.

[0003] Cofferdams are suitable for creating dry construction conditions within waters. The enclosure structure part of the cofferdam is usually designed in combination with a slope protection structure to enhance the cofferdam's blocking effect against external water, thereby reducing seepage phenomena. Currently, the slope protection structures used for cofferdams are usually directly formed by stacking tubular sand-filled bags, and the stacked sand-filled bags constitute a slope-shaped slope protection structure.

[0004] The existing slope protection structure, as a single-layer structure, lacks strong stability between structures. Under impact, the stacked weak parts of the slope protection structure are prone to loosening, resulting in seepage phenomena. In response to this, a large sand-filled tube bag slope protection structure is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present application provides a large sand-filled tube bag slope protection structure, which has advantages such as adding a stabilizing structure to a double-layer cofferdam structure to improve the stability of the slope protection.

[0006] To achieve the above object, the present application provides the following technical solution: A large sand-filled tube bag slope protection structure includes a double sand bag cofferdam and a toe weight sand bag, and a composite geotextile extended within the double sand bag cofferdam and pressed down by the toe weight sand bag;

[0007] The double sand bag cofferdam is composed of an inner cofferdam and an outer cofferdam stacked together. Among them, the inner cofferdam is stacked into a trapezoidal structure, the outer cofferdam is inclined and stacked against the trapezoidal slope of the inner cofferdam, and two square rods are continuously and fixedly installed on the surface of the composite geotextile, and a connection structure is arranged between the two square rods;

[0008] The connection structure includes a sliding tube fixedly installed on the top of the square rod and a connecting rod that is simultaneously slidably connected to the two sliding tubes.

[0009] Further, the composite geotextile includes a composite geotextile covering the outside of the outer cofferdam and an interlayer geotextile separated between the inner cofferdam and the outer cofferdam.

[0010] Furthermore, the composite geotextile is fixed at one end by being pressed down by the double sandbag weir as a whole, and the other end of the composite geotextile covers the outside of the slope of the outer weir and covers the top of the double sandbag weir and is pressed down and fixed by the sand-filled bag located above the water body. The two ends of the sandwich geotextile are fixed in the same way as the composite geotextile.

[0011] Furthermore, a bending rod is fixedly connected to one end of the composite geotextile covering the upper part of the double sandbag dam body, and the bending rod is placed in an L shape above the double sandbag dam body.

[0012] Furthermore, the connecting rod and the sliding tube include two groups symmetrically arranged at both ends of the two square rods.

[0013] Furthermore, a threaded tube is fixedly mounted on the top of the sliding tube, and a locking pin for abutting and restricting the connecting rod is mounted on the inner thread of the threaded tube.

[0014] Furthermore, a butterfly ear is fixedly connected to one end of the locking pin located outside the threaded tube.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This large sand-filled tube bag slope protection structure uses composite geotextile to block water from the outer weir structure of the double sandbag weir, effectively reinforcing the weak points of the traditional weir structure. At the same time, it combines the reinforced outer weir and the sloped inner weir to form a double sandbag weir, which can better adapt to the outer slope protection structure of the cofferdam and has good stability. It is beneficial to places where dry land construction conditions need to be formed in the water area, and projects that require the construction of complex underwater structures and waterside structures.

[0022] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0023] Please refer to Figures 1 to 4 , a large sand-filled tube bag slope protection structure in this embodiment includes a double sand bag weir body 1 and a toe weight sand bag 4, and a composite geotextile 2 is extended inside the double sand bag weir body 1 and is pressed down by the toe weight sand bag 4.

[0024] Specifically, the double sand bag weir body 1 is composed of an inner weir body 101 and an outer weir body 102 stacked. Among them, the inner weir body 101 is stacked into a trapezoidal structure, and the outer weir body 102 is inclined and stacked against the trapezoidal slope of the inner weir body 101, so that the double sand bag weir body 1 can form a trapezoidal slope protection structure.

[0025] With such a design, the inner weir body 101 serves as the existing slope protection structure, and the outer weir body 102 is used to enhance the edge structure. Compared with the single-layer sand bag weir body, its stability is stronger.

[0026] In this embodiment, the composite geotextile 2 includes a composite geotextile 2 covering the outside of the outer weir body 102 and an interlayer geotextile 3 separated between the inner weir body 101 and the outer weir body 102.

[0027] In the present application, the double-layer geotextile of the composite geotextile 2 and the geomembrane sandwiched between the double-layer geotextiles can be used to block the penetration of water, facilitating the formation of dry land conditions.

[0028] It should be noted that one end of the composite geotextile 2 is fixed by the overall pressing of the double sand bag weir body 1. The other end of the composite geotextile 2 covers the slope outside of the outer weir body 102 and covers the top of the double sand bag weir body 1 and is pressed and fixed by a sand-filled bag located above the water body. Both ends of the interlayer geotextile 3 adopt the same fixing method as the composite geotextile 2.

[0029] It is further explained that a bending rod 11 is fixedly connected to one end of the composite geotextile 2 covering the upper part of the double sand bag weir body 1. The bending rod 11 is placed in an L shape above the double sand bag weir body 1, and contacts the side of the sand-filled bag located above the water through the bending rod 11 to improve the setting stability of the composite geotextile 2.

[0030] In this embodiment, the composite geotextile 2 extends and folds at the slope edge end of the double sand bag weir body 1, and the toe weight sand bag 4 presses and reinforces the extended part of the composite geotextile 2.

[0031] In this embodiment, two square rods 5 are continuously and fixedly installed on the surface of the composite geotextile 2. A connecting structure is arranged between the two square rods 5 to control the distance between the square rods 5, so that the composite geotextile 2 forms a concave structure between the two square rods 5, improving the stability of the pressing of the foot sandbag 4 for fixation.

[0032] It should be noted that the connecting structure includes a sliding tube 6 fixedly installed on the top of the square rod 5 and a connecting rod 7 that is simultaneously slidably connected to the two sliding tubes 6. The connecting rod 7 and the sliding tube 6 include two groups symmetrically arranged at both ends of the two square rods 5.

[0033] In this embodiment, a threaded tube 8 is further fixedly installed on the top of the sliding tube 6, and a locking pin 9 for abutting and restricting the connecting rod 7 is installed inside the threaded tube 8 by threading.

[0034] Preferably, a butterfly ear 10 is fixedly connected to one end of the locking pin 9 located outside the threaded tube 8 for facilitating the rotation of the locking pin 9 by traction.

[0035] The working principle of the above embodiment is as follows:

[0036] By laying two layers of composite geotextiles 2 on the outside of the cofferdam, stacking sand-filled bags to form an inner weir body 101 above the composite geotextile 2, pressing and fixing one end of the composite geotextile 2, covering the other end of the inner layer of the composite geotextile 2 on the surface of the inner weir body 101, then stacking sand-filled bags on the outside of the inner weir body 101 to form an outer weir body 102, and immediately covering the outer layer of the composite geotextile 2 on the slope surface of the outer weir body 102 and covering it above the inner weir body 101, pressing and fixing the two layers of composite geotextiles 2 by the sand-filled bags above the water body, completing the setting of the slope protection. Blocked by the double-layer composite geotextile against the double sandbag weir body 1, the waterproof performance is effectively improved, and the stability of the slope protection structure in the water body is enhanced.
