Embodiment 1

[0027] as attached figure 1 As shown, a novel anti-explosion shock cable, comprising a cable (1), a support tube (2) of a nested cable (1), is characterized in that the inner and outer walls of the support tube (2) are provided with anti-explosion Protective layer (3).

[0028] as attached figure 2 As shown, the support tube (2) is provided with an outer protection tube (4), and the gap between the support tube (2) and the outer protection tube (4) is filled with an anti-knock protection filling body (3a), and the anti-blast The protective filler (3a) is made of at least one of fiber reinforced concrete, active powder concrete, polyurea, polyurethane foam, aluminum foam, aluminum honeycomb or rubber. The outer protection tube (4) is nested outside the support tube (2), the anti-blast protection filling body (3a) is filled between the support tube (2) and the outer protection tube (4), and the cable (1) passing through the inside of the support pipe (2).

Embodiment 2

[0030] as attached figure 1 As shown, a novel anti-explosion shock cable, comprising a cable (1), a support tube (2) of a nested cable (1), is characterized in that the inner and outer walls of the support tube (2) are provided with anti-explosion Protective layer (3).

[0031] as attached image 3 , attached Figure 4 Shown, the anti-blast protective layer (3) of the inner and outer walls of the support pipe (2) is an anti-blast protective coating (3b), and the described anti-blast protective coating (3b) is a polyurea coating or a polyurethane coating. Made of at least one of . The outer wall of the support tube (2) is sprayed with an anti-knock protective coating (3b), and the cable (1) passes through the inside of the support tube (2); the inner wall of the support tube (2) is sprayed with an anti-knock protective coating layer (3b), the stay cable (1) passes through the inside of the support tube (2).

Embodiment 3

[0033] as attached figure 1 As shown, a novel anti-explosion shock cable, comprising a cable (1), a support tube (2) of a nested cable (1), is characterized in that the inner and outer walls of the support tube (2) are provided with anti-explosion Protective layer (3).

Abstract

The invention discloses a novel cable with explosive blast resistance. The cable comprises a cable body (1) and a supporting tube (2) embedded with the cable body (1). The cable is characterized in that anti-explosion protective layers are arranged on the inner and outer walls of the supporting tube (2), and the supporting tube (2) can be sleeved with an outer protective tube (4) in an embedded mode. According to the cable, on the basis of unchanged original functions of the cable body, an anti-explosion structure is added to resist explosive blasts, and the cable has a multilayer structure for protection, so that damage on the cable caused by the direct explosive blasts is avoided.

Description

technical field [0001] The invention relates to a cable suitable for structures such as bridge engineering and construction engineering, in particular to a novel anti-explosion shock cable. Background technique [0002] As an important transportation infrastructure, bridges play a vital role in both military transportation and national economy. At present, terrorist activities are increasing worldwide, and bridge accidents caused by the threat of terrorist attacks and occasional explosions (such as the explosion of dangerous objects during vehicle operation) are increasing, which makes the anti-blast safety of bridge structures more and more concerned. At present, our country has not yet released the anti-blast protection design regulations for bridge structures, so it is necessary to carry out anti-blast protection design for bridge structures. [0003] The Chinese patent with the publication number CN205934724U discloses a kind of anti-collision steel strand cable-stayed ...
