Method for controlling use amount of fireproof sealing material of sleeve type cable

Abstract

The invention discloses a method for controlling the use amount of a fireproof sealing material of a sleeve type cable, and relates to the technical field of ship construction. The method specifically comprises the following steps: S1, determining the theoretical dosage of the fireproof sealing material of the sleeve type cable: carrying out element analysis on a cable penetrating through a node; determining a cable penetration rate, and carrying out model selection matching on a penetration piece and a sleeve; theoretical dosage calculation and checking are carried out on the sealing material sleeve and the sealant through software; s2, construction is carried out according to the following plugging technological process: the cables are arranged to penetrate through the penetration piece, and each cable is wrapped with a sleeve; the remaining space of the penetration piece is filled with a sleeve, and the sleeve is fixed in a cross wrapping mode; fireproof sealants are smeared at the two ends of the penetration piece in a sealed mode; finishing the surface of the sealant with a wet towel; and after construction is completed, a flashlight is used for irradiation for final detection. The method has the advantages that accurate theoretical dosage can be provided through auxiliary calculation of software; the construction process is optimized, waste of plugging materials is reduced, and the purposes of reducing cost and increasing efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for controlling the amount of fireproof sealing material for casing type cables. Background technique [0002] Due to the convenience, environmental protection and detachability brought by the casing type cable fireproof sealing material in the cable sealing construction, it has gradually been recognized by the shipyard, and its use in engineering ships has become more and more extensive. Although the casing-type cable fireproof sealing material has many advantages, the price is much higher than that of the cast-type cable sealing material, and the consumption is large and difficult to control, which increases the construction cost of the ship to a certain extent. [0003] In the existing technology, the information calculation of the cable penetration nodes is not perfect, and the penetration rate is not paid enough attention. The cable penetration rate of 40% in t...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method for controlling the amount of fireproof sealing material for casing type cables, which can solve the problem in the prior art that the cable penetration node data cannot be simulated and calculated, resulting in the inability to finally determine the fireproof sealing material for casing type cables The theoretical dosage and the plugging dosage of each penetration node during construction cannot be quantified, the waste of fireproof sealing materials is serious, and the large dosage leads to high construction costs
