Description

A co-constructed area-saving indoor and outdoor fire pool

technical field

The utility model relates to the technical field of building fire protection, and more specifically relates to a joint-built type saving area indoor and outdoor fire-fighting pool.

Background technique

At present, performance-based design is the most widely used in the field of building fire protection design in my country. According to the nature and scale of different buildings, appropriate fire protection design content is selected, and fire safety engineering is integrated into safety goals.

Most of the current fire extinguishing systems still use water fire extinguishing system as the main fire extinguishing means, which involves the selection and design of fire water sources and fire pressure. In order to fully utilize and develop the commercial value of the building, the construction party hopes to The fire pool and the fire pump room 41 are located at the bottom of the basement. However, from the perspective of fire safety, the national fire laws and regulations clearly stipulate that the fire pump room attached to the building should not be installed on the third floor underground or below or on the underground floor where the height difference between the indoor floor and the outdoor entrance and exit floor is greater than 10m. There are also: fire-fighting pools for storing outdoor fire-fighting water or fire-fighting pools for fire trucks to take water. The fire-fighting pools should be equipped with water intakes, and the water absorption height should not be greater than 6.0m. In this way, the setting of fire-fighting pool and fire-fighting pump room 41 has been greatly restricted. It is particularly important to optimize the design of the fire-fighting pool and pump room to meet the needs of the construction party and meet the requirements of national regulations.

Considering the height of the building, it is generally more appropriate to set the fire pool and fire pump room 41 on the second basement floor (to meet the requirement that the height difference of the code does not exceed 10m), but some buildings need to set up outdoor fire pools and water intakes, and the fire The water absorption height of the vehicle should not be greater than 6m. Except for the distance between the pump set of the fire truck and the ground height of about 1m, the height difference between the minimum effective water level of the outdoor fire-fighting pool and the ground of the outdoor building should not exceed 5m, so the outdoor fire-fighting pool cannot be set in The second basement floor (with a height difference of about 9m from the ground). The design method commonly used at present is that the outdoor fire-fighting pool and the outdoor fire-fighting pump room 41 are separately arranged on the first basement, and the indoor fire-fighting pool 40 and the fire-fighting pump room 41 are separately arranged on the second basement. However, the outdoor fire pump set is installed on the basement floor. Considering that the minimum effective water level of the outdoor fire pool should be higher than the height of the vent hole of the fire pump set and the height difference between the ground of other outdoor buildings should not exceed 5m, the real fire protection The effective water depth of the pool is greatly reduced, and the floor area of the outdoor fire pool needs to be increased, which reduces the commercial use value of the building.

In view of this, we propose a co-constructed area-saving indoor and outdoor fire pool.
