Embodiment 1

[0028] This embodiment mainly describes an all-round fire-proof and explosion-proof device for tunnel dense cables. The device is a three-dimensional structure composed of fire-resistant paint, cable brackets, refractory bricks, fire-proof blankets, inorganic density boards, rock wool boards, fire-proof boards and other materials. The components are marked in the attached drawings, and detailed descriptions are given according to their installation and arrangement positions:

[0029] In this embodiment, dense cables are installed in the tunnel. The cables use 110KV or 220KV cable joints. The cable joints are provided with fireproof paint. The joints are fixed on the cable brackets. Fireproof boards are installed on the cable brackets. Support frame, inorganic MDF is installed on the support frame, fireproof blanket is wrapped around the joint, and the cable joint on the side of the joint is installed in the support frame. In addition, as a preferred design, fireproof blanket is...

Embodiment 2

[0032] An omni-directional fire-proof and explosion-proof method for tunnel dense cables, based on the above-mentioned omni-directional fire-proof and explosion-proof device for tunnel dense cables, includes the following steps:

[0033] S1. Paint fireproof paint on both sides of the cable joint, wrap fireproof tape, and then wrap fireproof blanket;

[0034] S2. The upper side of the connector is fixed on the cable bracket with long bolts, and the fireproof board bracket is installed on the long bolt, the fireproof board is fixed on the fireproof board bracket, and the rock wool board is installed on the fireproof board;

[0035] S3. The bottom of the cable joint is built with refractory bricks to form a supporting frame, and inorganic MDF is installed on the frame;

[0036] S4, the upper and lower cables of the joint are wrapped around the fire blanket;

[0037] S5. The side cable of the connector is built into a support frame with a fireproof board bracket, and then the upp...

Abstract

The invention belongs to the technical field of tunnel dense cable fire prevention and explosion prevention, and particularly relates to a tunnel dense cable all-dimensional fire prevention and explosion prevention device which uses materials such as a fire prevention coating, a cable support, a refractory brick, a fireproof blanket, an inorganic density board, a rock wool board and a fire prevention board, and provides a tunnel dense cable all-dimensional fire prevention and explosion prevention device and a corresponding method. Therefore, the fireproof and explosion-proof capability of the dense cable is remarkably improved, and the use cost is reduced.

Description

technical field [0001] The present application belongs to the technical field of fireproof and explosion-proofing of tunnel dense cables, and in particular relates to an omnidirectional fireproof and explosion-proof device for tunnel dense cables. Background technique [0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute prior art. [0003] At present, cables, especially dense cables, have poor fire-proof and explosion-proof capabilities. How to find an effective and inexpensive fire-proof and explosion-proof solution is the key point at present. SUMMARY OF THE INVENTION [0004] In order to solve the above problems, the present application provides an all-round fire-proof and explosion-proof device for tunnel dense cables. [0005] The purpose of the present application is to provide an all-round fire-proof and explosion-proof device for a dense cable in a tunnel and a correspond...
