Type of human defence work
Human defence works, as we usually call them, can be classified according to the method of construction and the environmental conditions in which they are carried out: pits, tunnels, excavations and auxiliary。
1. Pipelines: constructed in mountainous or hilly areas, where the bulk of the main mass of the ground and entry and exit are largely under-excavated. The following is a design for the engineering of mid-green land underground man in shanghai, designed to be a crater。
2. The tunnel: it is built on flat ground and most of its main surface is significantly lower than the clandestine human defence work at the entrance or exit. Here's a picture of the cool spot for the people in sian。
3. Excavation: construction using explicit excavations, with no human defence works above permanent ground buildings, also referred to as individual excavations。
4 auxiliary: basements with operational air defence. That is to say, the construction of human defence works using explicit excavations and the construction of permanent ground buildings above them。
Human protection-related engineering knowledge
Human protection engineering recognition
In general, human defence works are carried with the use of human security badges, signboards and instructions for the use of human security channels. A number of elevators also carry a human-friendly warning to the residents that nearby air defence basements can be used for protection during air strikes。
Is the underground building space all manned
The underground space component includes basements, underground parking lots and metros, which are protected only by protected areas for human protection. Other than this, the role of unarmed areas, basements, squares, etc. Is more limited。
Each of the security entrances is equipped with an engineering sign and a corresponding security route sign to guide citizens to the area under emergency conditions. Access points are used in the course of human combat areas and are visible as long as they enter the air defence basement。
Attention to access to engineering protection
(b) rapid access to human defence works when advance warnings are received
(b) complying with the guidance of the responsible persons, so that they are not crowded or noisy
A backpack, not a bag, not a bag
Hold the kids tight and don't let them go
When there is no light, leave your right hand, touch it on the right side and move quickly to human defense。
Care when shielding in human defense works
(b) rest in the designated position, keep the children under control and not wander around
(a) personal protective gear and the close placement of acoustic objects without prejudice to the movement of others
Vegetables, hulls and stains are sealed in plastic bags
(a) no smoking, no burning, no vomiting, water and spare tea
Refrain from using random anti-aircraft basement protection equipment
Air defence basements will not be vacated without permission。
