Gas and other operations.

2 Countermeasures We analyze the cause of the accident. Seven is to suck, lessons. In order to prevent similar occurrences from happening again, in the face of the grim situation of construction machinery accidents, enterprises should start from the following aspects.

Business leaders must take safety work as a major event. Don't just focus on production safety, production safety is the biggest economic benefit. Strengthen the management of enterprises, record the corresponding regulations, strengthen supervision and management, and ensure the implementation of the system. It is necessary to use a scientific attitude to prevent the occurrence of an accident. It is not a bad luck or a bad luck. It is a question of whether the safety work is really home. Construction machinery and equipment should be checked regularly every month, and it is found that timely rectification is required.

When purchasing equipment, strictly control the procurement and select products with excellent quality and safety. At present, there are many kinds of elevators and tower cranes in the construction machinery market. The price difference between the enterprises is large. Users should consider the product quality and safety to comprehensively consider the products, and do not enter the misunderstanding of low-cost purchase. Although some manufacturers hold a full set of documents approved by the government, the quality of the products is inferior. There are safety hazards. It is difficult for the air compressors to be used. Before using the machine, it is necessary to scientifically select the parking position and determine the gas pipeline laying according to the nature and tasks of the construction. The method to ensure efficient and safe construction.

After the construction site of one press parking position is determined, select the parking position of the air compressor, and consider the following points as close as possible to the working surface. In order to reduce the length of the gas pipeline and the loss of gas pressure, the geology is solid, the terrain is flat, and there is enough area to facilitate the mechanical appearance of the 3+ salty threatened by the flash flood and the attack of the flying stone during the blasting, and should be associated with the inflammable and explosive warehouse. And letter. Once an accident occurs, the company’s economy and credit losses are greatly enhanced. Equipment maintenance and repair, 技术 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安 安Record, so that the quality and safety performance of the equipment after maintenance is guaranteed, to prevent the use of safety hazard equipment investment in business technology training, improve the quality of business optimization. The training of operators should be targeted and practical. It is necessary to combine the characteristics of each one and consider one from each type of work. It is necessary to comprehensively analyze the safety accidents that may occur in the position of the work, the possible safety corners and safety hazards, and implement preventive measures. , set out the operating procedures, and the personnel should be educated on the technical basis. Jin Zhiyong, the author of Wang Gangguo, 1964, male, Ningbo, Zhejiang, engineer, Room 504, No. 21, Zhongxiang, Jiangbei District, Ningbo.

The machining room is kept at a fixed distance of 4 if it is operated by an electric motor.

In addition, when the air compressor is fixed for a long time in a certain position, it should be set up to prevent the rain from being exposed to the sun and play a role in protecting the cold.

2 The laying pipe of the gas pipeline should be laid along the shortest route to minimize the turning of 0. The necessary pipe fittings should be set on the pipeline, such as the installation of the switch and the check valve between the air compressor and the gas storage module. Between the gas pipelines, women's owing, etc., but the number should be minimized; when the pipe is changed from diameter to diameter, the pipe diameter must not change suddenly. In the same pipeline, no local water accumulation is allowed in the small-diameter pipeline. Therefore, there should be a slope of 1200,300, and the water separation at the lowest point is disappointing. The selection and laying method of 1 shall not affect the progress of the application and the entry and exit of the mechanical vehicle as well as the safety and reliability.

According to the on-site topographic gas transmission distance and the distribution of pneumatic tools, the pipeline layout is drawn.

According to the layout of the pipeline, the material plan is prepared, and it is ready to use the white ash to carry out the marking or nailing according to the layout of the pipeline.

Pipe fittings in pipes should be carefully inspected prior to installation and can only be used if they meet the standards.

After the on-site cutting and welding is completed, the pipe must be cleaned, and it is not allowed to leave the residue of metal slag and other dirt.

Where the directional requirements of the valve components, in the installation, should be noted that the direction should be consistent with the flow of compressed air.

At the pipe flange connection, the inner diameter of the sealing gasket should not be smaller than the inner diameter of the pipe, so as to avoid increasing the resistance inside the pipe. The joints should be tightly laid in the pipeline, and should be avoided in the summer. After the pipe is laid, the compressed air should be used to blow the pipe. And check that there is no air leakage at each joint, and those that meet the requirements should be dealt with in a timely manner.

When the pipe is horizontally laid in the horizontal tunnel, the pipe with a diameter larger than 50 stomach shall be fixed on the cross arm, and the pipe with a diameter of 5 or less shall be hung on the frame with a hoop. The distance between the support points of the pipe shall comply with the provisions of 1 so that the deflection of the pipe does not exceed 5, otherwise the deflection is too large to produce water accumulation.

The distance between the support of the bamboo road horizontally and the support point of the diameter of the pipe is outside. The pipe outside the external tunnel of the tunnel inside the tunnel shall be laid or buried underground if it passes through the roadway. The height of the overhead is to ensure that the vehicle can pass, and the inspection well should be left at the pipe joint buried in the ground. In the winter construction, in order to prevent freezing and to avoid the influence of low temperature on the air pressure, the heat is damaged, and the insulating material is used to wrap the straw or the like, or to be laid. 51 ditch towel and check at the joint.

In the inclined tunnel, the pipe application snap ring is fixed on the tunnel bracket. The separation between the support points should be shorter than when the horizontal is laid.

In a vertical tunnel, the pipe can be fixed to the ledge along the wall of the pit and reinforced with gussets. The distance between the under-bearing points is not more than when the hose is used for air supply, and the air supply distance is 506, 1 or parallel. The series connection is to gradually reduce the inner diameter of the hose in the direction of the pressure gas flow; the parallel connection is to make the pressure gas first pass through two hoses, and then into the thicker hose, and finally to the pneumatic machine.
