Novel sand filled bag

Abstract

The invention relates to a novel sand filled bag. The novel sand filled bag comprises a sand bag body which is composed of an upper bag body and a lower bag body. The upper bag body and the lower bagbody are both made of a geotechnical cloth material, and the peripheral edges of the upper bag body and the lower bag body are fixedly connected in the circumferential direction. The upper bag body isprovided with a plurality of upper snap joint sets in the length direction of the sand bag body, the lower bag body is provided with a plurality of lower snap joint sets in the length direction of the sand bag body, and the positions of the upper snap joint sets are aligned to the positions of the lower snap joint sets up and down. The upper bag body is provided with a plurality of sand inlets, and the sand inlets are provided with sand inlet assemblies. Each sand inlet assembly comprises a connection base which is arranged on the corresponding sand inlet and provided with an external threadand further comprises a corrugated pipe and a buckling cover with an internal thread, wherein the lower end of the corrugated pipe is fixedly connected with the inner wall of the connection base, andthe buckling cover is in threaded connection with the connection base. The novel sand filled bag is simple in structure, a seal opening is smooth and is not prone to disengaging, the size can be regulated to a certain degree, and the novel sand filled bag is conveniently used in dredging construction.

Description

technical field [0001] The invention belongs to the technical field of dredging construction, in particular to a novel sand-filled bag. Background technique [0002] In the field of dredging construction technology, geotextile sand-filled bag devices are more commonly used. Compared with traditional block stones and prefabricated concrete components, geotextile sand-filled bags are made of tubular geotextiles and filled with dredging materials or mud. The geotextile sand-filled bag has the advantages of reducing workload, shortening the construction period, saving engineering costs, using local silt sand and local equipment, and reducing engineering maintenance costs. At the same time, in some areas where there is an extreme shortage of sand and gravel, it is also an economical and efficient method to use geotextile sand-filled bags. [0003] Existing sand-filling bags generally include a tubular sand-filling bag body, and a plurality of sand-filling ports are arranged in t...

AI Technical Summary

Problems solved by technology

[0007] The advantages and positive effects of the present invention are: the present invention provides a new type of sand-filled bag with a simple and reasonable structural design. The sand inlet assembly is set on the sand mouth, which solves the problem of easy disengagement and material leakage caused by the binding and fixing of the sand inlet of the sand bag in the prior art.
