Geotechnical sand sausage bag with joint

Abstract

A geotechnical sand bag comprises connecting parts comprises a bag body unit, an auxiliary unit, a sealing suture and two auxiliary sutures; the bag body unit comprises a surrounding part, a virtually-planar end part and an accommodating space defined by the surrounding part and the end part through surrounding; the auxiliary unit comprises the two connecting parts connected to the end part and two buffer spaces defined by the connecting parts through surrounding; the sealing suture is arranged at the end part and the connecting parts; the auxiliary sutures are arranged between the connectingparts and the end part; and angles are formed by the auxiliary sutures and the sealing suture. The connecting parts and the auxiliary sutures are arranged, when the filling pressure is excessively high, the auxiliary sutures can be broken firstly, and the corresponding connecting parts bulge, so that a user is warned, and damage to the geotechnical sand bag is avoided.

Description

technical field [0001] The invention relates to a geotechnical sausage bag, in particular to a geotechnical sausage bag with a connecting part. Background technique [0002] Geotechnical sand sausage bags are usually used in river and sea engineering or environmental engineering, and can be used to build marine structures, such as breakwaters, jetties, dikes, etc., or to prevent sand and gravel from being washed away by river water or waves. [0003] Geotechnical sand sausage bags are generally composed of geotechnical woven fabrics, filled with sand, soil or other fillers, and form a flexible permeable structure after filling and filling, which can dissipate the impact of water flow. [0004] refer to figure 1 , 2 The existing geotechnical sand sausage bag is processed by first forming a tubular bag body 91 with geotechnical woven cloth, and then sewing the two ends of the bag body 91 with two sealing sutures 92 to close the mouth. [0005] Because this kind of sewing me...

Problems solved by technology

[0008] However, since the flat plate, the bag body and the straps of a single geotechnical sand sausage bag are independent components, the joints are likely to form weaknesses in the overall structure. Taking the most commonly used stitching method as an example, in During the suturing process of the flat plate and the bag body, the puncture of the sewing needle will inevitably cause damage to the fabric and reduce the tensile strength of the suture. Therefore, during the filling process, the fabric suture will be pulled by the suture, and the force is relatively non-sewing. are more concentrated, so damage is more likely to occur there

Therefore, in this patent, the flat plate and the bag body are respectively closed by annular sewing, compared with figure 1 , 2 The straight line sealing method increases the suture area, so the probability of damage to the geotechnical sand sausage bag also increases

[0009] In addition, during the filling and filling process of the geotechnical sand sausage bag, the bottom position where the flat plate is combined with the bag needs to bear not only the filling pressure, but also the gravity of the filling material, so when there is a structural weakness , the probability of failure will increase significantly, so although this method solves the aforementioned problem of discontinuous gaps, it reduces the overall structural strength

[0010] In addition, during the filling process of the geotechnical sausage bag, the geotechnical sausage bag is often broken during filling due to excessive filling pressure. Once the geotechnical sausage bag is ruptured during filling, other than In addition to causing failure of the whole item, at the same time, because the inside of the geotechnical sand sausage bag is a high-pressure environment before the rupture, and the size of the bag is usually very large, a large amount of filling material gushed out after the rupture has a strong impact, which will It poses a major threat to the safety of surrounding construction personnel and machines
