Description

Technical Field

[0001] The invention relates to an underground integrated pipe gallery, in particular to a cable fireproof door structure used in the integrated pipe gallery. Background Art

[0002] With the development of underground engineering in my country, underground buildings such as tunnels, pipe galleries, and underground spaces are gradually increasing. According to relevant regulations, fire doors need to be installed at certain intervals in trenches, pipe galleries, and tunnels where power cables are laid, and pipe holes are often reserved at fire doors for laying power cables.

[0003] The power cable is laid along the floor on a pulley pulled by manual or mechanical equipment. There are currently two ways to pass through a fire door: First, refer to Figure 1 , the power cable 2 is laid along the reserved hole 1, and when it is laid on the pulley 3 along the floor, it needs to be close to the reserved hole. The power cable 2 and the reserved hole 3 have up and down and left and right deviations. When the power cable is laid along the pulley and transported to the power cable bracket, it is easy to cause the outer skin of the power cable to wear, causing safety hazards. Second, the fireproof partition wall is destroyed. After the power cable is laid, a new fireproof partition wall is built. Each time the power cable is laid, the process of destruction-construction-destruction is repeated, resulting in great waste. Summary of the invention

[0024] The present invention is further described in detail below by means of specific embodiments in combination with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] See also Figures 2 to 4 , the figure shows a cable fire door structure used in a comprehensive pipeline corridor.

[0026] The cable fire door structure is mainly composed of a comprehensive pipe gallery 1, a side partition wall 2, a middle fire door 3 and a side fire door 4.

[0027] The integrated pipe gallery 1 is formed below the ground. A power cable compartment 10 or other functional compartments are formed inside the integrated pipe gallery 1. The power cable compartment 10 extends in the front-rear direction.

[0028] The side partition walls 2 are respectively placed on the left and right sides of the inside of the power cable compartment 10. The side partition walls 2 are double-layer wall structures. The side partition walls 2 have a front partition wall layer 22, a rear partition wall layer 23, and a partition wall connection portion 24. The front partition wall layer 22 and the rear partition wall layer 23 are spaced front and back. Both the front partition wall layer 22 and the rear partition wall layer 23 extend from the side wall of the power cable compartment 10 toward the direction of the middle fire door 3. The partition wall connection portion 24 extends backward from the middle fire door 3 end of the front partition wall layer 22 to the middle fire door 3 end of the rear partition wall layer 23. Among them, the front of the front partition wall layer 22 and the back of the rear partition wall layer 23 are both fire-facing surfaces and require fire protection.

[0029] The side partition wall 2 is provided with a reserved hole 20 for the power cable 6 to pass through in the front-to-back direction. The reserved hole 20 of the partition wall passes through the front layer 22 of the partition wall and the rear layer 23 of the partition wall respectively. The reserved hole 20 of the partition wall has a main hole path 201 extending in the up-down direction and more than two branch holes 202 extending in the left-right direction. The main hole path 201 is connected with each branch hole path 202. Each branch hole path 202 is arranged on the side of the main hole path 201 away from the middle fire door 3, so that the reserved hole 20 of the partition wall forms a comb-like structure. The width of the main hole path 201 is set to be relatively large, and the width of the main hole path 201 needs to accommodate the passage of multiple groups (roots) of power cables 6, so as to solve the deviation caused by laying cables along the reserved holes in the prior art, and at the same time will not cause the outer skin of the power cable 6 to be worn. The width of the branch hole 202 is set relatively small, and the width of the branch hole 202 only needs to accommodate a single group (root) of power cables 6 passing through.

[0030] Cable accommodating grooves 2020 are arranged at intervals along the left-right direction on the hole branch 202. The cable accommodating grooves 2020 are used to accommodate the power cable 6. The cable accommodating grooves 2020 are composed of an upper recessed portion formed on the top surface of the hole branch 202 and a lower recessed portion formed on the bottom surface of the hole branch 202. The upper recessed portion cooperates with the upper half of the power cable 6, and the lower recessed portion cooperates with the lower half of the power cable 6.

[0031] It should be noted that the number of the branch holes 202 and the cable accommodating grooves 2020 is determined according to the number of the laid power cables 6. The more the number of the power cables 6 is, the more the branch holes 202 and the cable accommodating grooves 2020 are.

[0032] The intermediate fire door 3 is placed between the partition wall connection parts 24 .

[0033] The pulley block 5 is placed inside the power cable compartment 10. The pulley block 5 is arranged along a straight line between the feeding port and the traction port of the power cable compartment 10, and the straight line passes through the main hole path 201.

[0034] The side fireproof board 4 is placed in front of and / or behind the side partition wall 2. In order to better fix the side fireproof board 4, a reserved partition wall slot 21 for accommodating the side fireproof board 4 is formed on the front and / or back of the side partition wall 2. The side fireproof board 4 is placed in the reserved partition wall slot 21 and fixed in a snap-fit ​​manner. The side fireproof board 4 at least covers the main hole road 201 part in the side partition wall 2. In this embodiment, except for the hole branch road 202 part in the front and / or back of the side partition wall 2, the other parts are covered by the side fireproof board 4. The gap space formed by the hole branch road 202 and the power cable 6 is blocked with fireproof putty 7. Thereby, the fire protection requirements are met without destroying the fire door partition wall, and the construction and installation of the power cable 6 are also facilitated.

[0035] The construction method of the power cable passing through the fire door in the integrated pipe gallery includes the following steps and is performed in sequence:

[0036] Step S1, setting up an integrated pipe gallery 1. A power cable compartment 10 is formed inside the integrated pipe gallery 1, and the power cable compartment 10 extends in a front-to-back direction.

[0037] Step S2, setting side partition walls 2. The side partition walls 2 are respectively placed on the left and right sides of the inside of the power cable compartment 10. The side partition walls 2 are formed with partition wall reserved holes 20 that penetrate in the front-to-back direction for the power cable 6 to pass through. The partition wall reserved holes 20 have a main hole road 201 extending in the up-down direction and more than two branch holes 202 extending in the left-right direction. The width of the main hole road 201 is greater than the width of each branch hole 202. The main hole road 201 is connected to each branch hole 202, so that the power cable 6 can be shifted from the main hole road 201 to each branch hole 202.

[0038] Step S3, setting an intermediate fire door 3. The intermediate fire door 3 is placed inside the power cable compartment 10 and between the side partition walls 2 on the left and right sides.

[0039] Step S4, setting a pulley block 5, wherein the pulley block is placed inside the power cable compartment 10, and the pulley block is arranged along a straight line between the feeding port and the traction port of the power cable compartment 10, and the straight line passes through the main hole path 201.

[0040] Step S5, laying the power cable 6: a power cable winding drum is arranged at the feeding port of the power cable cabin 10. A traction machine or manual traction is arranged at the traction port of the power cable cabin 10. With the assistance of the pulley block 5, the power cable 6 passes through the hole main road 201 from the feeding port of the power cable cabin 10 to the traction port of the power cable cabin 10, and then the power cable 6 is shifted from the hole main road 201 to each hole branch road 202.

[0041] Step S6, setting a side fireproof board 4. The side fireproof board 4 is placed in front of and / or behind the side partition wall 2.
