Fire-fighting elevators are elevators with certain functions for fire-fighting and rescue by firefighters in case of fire in buildings. The fire-fighting elevator usually has perfect fire-fighting functions: it has dual power supply, i.e. in case the power supply of the working elevator in the building is interrupted, the emergency power supply of the fire-fighting elevator can be automatically put together and can continue to run. It has emergency control function, i.e. when there is a fire on the upper floor, it can accept the instruction to return to the first floor in time, and not continue to accept passengers, and can only be used by firefighters. It reserves an emergency evacuation exit at the top of the car, so that in case the opening mechanism of the elevator fails to work, it can also be evacuated from here. For the main part of high-rise civil buildings, a fire elevator should be set up when the floor area does not exceed 1500 square meters.

The difference between fire-fighting elevators and ordinary elevators: ordinary elevators are prohibited to be used in case of fire. Fire-fighting elevators can be used by fire-fighting personnel for fire-fighting and rescue in case of fire.

Material assurance measures

1、Establishment of material incoming inspection system

Adhere to the material incoming inspection system to ensure that raw materials, semi-finished products and finished products meet the quality requirements of technical specifications before use.

(1) Strictly control the quality of raw materials and semi-finished products. The cement, pipes and fittings used in the construction should have the corresponding factory certificate of conformity and quality certificate, and should also be tested according to the specification requirements for sampling, and only after passing the test for the construction of the project. The raw materials that fail to meet the design requirements by inspection shall be downgraded and used or returned according to the specific situation.

(2) The stacking of raw materials and semi-finished products shall be neatly stacked in accordance with the requirements of ISO9001 operation manual, classified and divided into specifications, and hung with good identification plates to prevent misuse.

(3) The company's engineering department and material and equipment department shall conduct monthly statistical analysis of unqualified semi-finished products, finished products or unqualified raw materials, focusing on some processes that are prone to quality problems, analyzing the different effects of the materials used, processes, production equipment, operating procedures, operator's skills or other factors on the quality, and propose and take preventive measures differently.

2、Quality control of main materials

(1) sand and gravel

Sand and gravel for construction and concrete are supplied by the sand and gravel quarry near Shawan in Panyu and the sand quarrying area on the sea surface of Roxanwei in Hengmen waterway in Zhongshan City. 8 ships are used for sand filling and 2 sets of sand blowing equipment are used for sand filling. Sand and gravel for cement concrete were transported to the site by car.

(2) Cement concrete

According to the requirements of the owner, the concrete for this project is self-mixed concrete, which is mixed centrally by concrete production equipment with automatic measuring devices. Our department set up a centralized mixing station for cement concrete and stabilized stone chips on site to meet the supply of concrete and cement stabilized layer construction.

The concrete mix ratio was designed according to the requirements of different parts and reported to the supervising engineer for approval. During the construction process, it was also necessary to make adjustments according to different weather requirements so that the concrete would meet the design requirements.

Check the slump and compatibility of concrete before pouring, and prepare sufficient number of test pieces according to the specification requirements.

(3) Prefabricated components and drainage materials

The prefabricated components and drainage pipe materials should have the factory certificate of conformity when they are delivered, and the indicators should meet the design requirements before they are delivered.

3、Control of material supply

(1) The project department will organize the relevant personnel to evaluate the pipe and cement suppliers and select the material suppliers with perfect qualification, complete certificates and good reputation.

(2) Construction sheet piles and other swing materials are transported to the construction site by trucks and long-board transporters. Insufficient part of the turnover materials are purchased in the vicinity to ensure the construction requirements.

(3) Adhere to the material incoming inspection system to ensure that raw materials, semi-finished products and finished products meet the quality requirements of technical specifications before use. In addition to the corresponding quality certificates, the cement, pipes and concrete used in the construction must also be tested according to the specifications, and only after passing the test can they be used, and the raw materials that fail to meet the design requirements are returned.

4、Material transportation plan

The incoming and outgoing transportation of bulk materials such as earth, sand and gravel, pipes and other semi-finished and finished components are carried out according to the plan in order to reduce the impact on the surrounding traffic and construction site during transportation as much as possible. It is planned that 8 load cars and 2 flatbed trucks will be used for material transportation.

The transportation of bulk materials is guaranteed to be carried out in accordance with the regulations on the transportation of bulk materials, and relevant documents such as residual sludge discharge certificates are prepared.
