Abstract
The utility model belongs to the technical field of urban underground comprehensive pipe gallery engineering, and provides an intercommunicating channel inside a comprehensive pipe gallery, which comprises a comprehensive cabin, an electric cabin, a natural gas cabin and other cabins; intercommunicating channels are correspondingly arranged below the bottom plates of the comprehensive cabin, the electric power cabin, the natural gas cabin and other cabins, and steel ladders are arranged between the cabins and the intercommunicating channels corresponding to the cabins. Lie in each cabin steel ladder upper end, install and prevent guardrail bar, prevent that cabin personnel from falling to intercommunication passageway in, causing unexpected injury. Each intercommunicating channel is formed by the isolation arrangement of a fire partition wall, and a normally closed first-level fireproof door is arranged on the fire partition wall, so that the intercommunicating of the cabins can be realized, and the cabins are ensured to be independent fireproof intervals; the utility model discloses when not increasing personnel access & exit node, the personnel of being convenient for pass in and out each cabin inside the utility tunnel, solved utility tunnel daily patrol and examine, visit inconveniently, the maintenance, the untimely defect of speedily carrying out rescue work.
Description
Technical Field
The utility model belongs to the technical field of city utility tunnel engineering, be the structure that sets up inside the utility tunnel, be convenient for daily patrol and examine, maintain, speedily carry out rescue work and visit the intercommunication passageway that personnel passed in and out each cabin inside the utility tunnel.
Background
The comprehensive pipe gallery is built under the city and is used for containing structures and accessory facilities of two or more types of city engineering pipelines. For satisfying inside personnel business turn over of utility tunnel, daily inspection, maintenance, demand such as speedily carrying out rescue work, utility tunnel personnel access & exit should be combined the setting with mouthful, hoist and mount mouth, air intake of fleing for one's life, and be no less than two.
For long-distance, multi-cabin and large-scale comprehensive pipe galleries, the design distance of each person entrance is large in consideration of economy, and each cabin of the comprehensive pipe gallery is an independent space, and daily inspection, maintenance, emergency rescue and visitors need to enter and exit each cabin of the comprehensive pipe gallery through personnel outlets, so that the daily inspection and visit are inconvenient, and the maintenance and emergency rescue are not timely.
Disclosure of Invention
Aiming at the problems that the existing long-distance, multi-cabin and large-scale comprehensive pipe gallery has large designed distance of the entrances and exits of each person, the comprehensive pipe gallery is inconvenient to inspect and visit in daily life, and the maintenance and emergency rescue are not timely; an object of the utility model is to provide an inside intercommunication passageway of utility tunnel is convenient for advance, go out each cabin inside the utility tunnel.
In order to realize the purpose, the utility model discloses a technical scheme be: an intercommunicating passage inside a comprehensive pipe gallery comprises a comprehensive cabin, an electric cabin, a natural gas cabin and other cabins; the method is characterized in that: intercommunicating channels are correspondingly arranged below the bottom plates of the comprehensive cabin, the electric power cabin, the natural gas cabin and other cabins, and steel ladders are arranged between the cabins and the intercommunicating channels corresponding to the cabins.
Further, be located each cabin steel ladder upper end, install and prevent guardrail bar, prevent that cabin personnel from falling to intercommunication passageway in, causing unexpected injury.
Furthermore, a first-level fireproof door is arranged on a fireproof partition wall of each cabin intercommunication channel, and is normally closed at ordinary times, so that cabin intercommunication can be realized, and each cabin is ensured to be an independent fireproof interval; when the personnel go into and out of each cabin in daily inspection, maintenance, emergency rescue or visit, the first-class fireproof door can be opened to enter different cabins.
The utility model has the advantages of very strong practicality is applicable to extensive popularization and application, and its main advantage lies in: utilize the inside intercommunication passageway of utility tunnel, when not increasing personnel access & exit node, the personnel of being convenient for pass in and out each cabin inside the utility tunnel, solved utility tunnel daily patrol and examine, visit inconvenient, the maintenance, speedily carry out rescue work untimely defect.

Detailed Description
For better understanding the utility model provides an inside intercommunication passageway of utility tunnel, it is right to combine the figure below the utility model discloses do detailed explanation.
As shown in fig. 1 and 2: an intercommunicating passage inside a comprehensive pipe gallery comprises a comprehensive cabin 1, an electric power cabin 2, a natural gas cabin 3 and other cabins 4; intercommunicating passages 7 are correspondingly arranged under the bottom plates of the comprehensive cabin 1, the electric power cabin 2, the natural gas cabin 3 and other cabins 4, and steel ladders 5 are arranged between each cabin and the corresponding intercommunicating passages 7. The persons in the cabins can move down into the intercommunicating gangway 7 as indicated by the arrows in the steel ladder 5 of fig. 2.
In order to prevent the cabin personnel from accidentally falling into the intercommunicating channel to cause accidental injury; furthermore, be located each cabin, steel ladder 5 upper end is installed and is prevented guardrail bar 6, prevents guardrail bar 6 and is the stainless steel material preparation, neither can the corrosion, again pleasing to the eye.
See fig. 3; each intercommunicating channel 7 is formed by the isolation arrangement of a fire partition wall 9, and each cabin is ensured to be an independent fire-proof interval. In order to realize the intercommunication of cabins, the fire partition wall 9 is provided with a first-level fire door 8, the first-level fire door 8 is normally closed when being flat, and the first-level fire door 8 can be opened to enter different cabins for work and visit when daily inspection, maintenance, emergency rescue and visitors enter and exit each cabin. The persons in the respective intercommunicating gangways 7 can move up into the respective compartments as indicated by the arrows of the steel ladder 5 in fig. 3.
