Description

Technical Field

[0001] The invention relates to the field of tunnel engineering construction, in particular to a tunnel advancing trolley with an integrated ventilation structure, which is used for dust control and ventilation and dust removal during tunnel advancing. Background Art

[0002] In traditional tunnel advancement projects, a large amount of dust is generated due to the crushing and blasting of rock formations. Traditional tunnel ventilation structures are usually achieved by setting up independent fans and ducts. The fan is responsible for supplying or extracting air, and the duct guides the air into the tunnel or discharges it to the external environment. However, there are some defects in the traditional ventilation system. First, the layout of the traditional ventilation system is not flexible enough. Since the fan and duct are set up independently, their positions and quantities often cannot be flexibly adjusted according to the needs of the specific construction stage. This may lead to poor ventilation effect or waste of resources. Secondly, the traditional ventilation system is connected to other equipment. Usually, the ventilation system needs to be connected to other equipment such as lighting equipment and power lines, which may cause pipe blockage and difficulty in maintenance. Once one of the equipment fails, the entire ventilation system may be affected, and the traditional ventilation system has limited consideration for dust removal and ash removal functions. During the tunnel construction process, the generation of dust and particulate matter is inevitable, and the traditional ventilation system cannot effectively deal with these problems, which may lead to the deterioration of the construction environment and threats to the health of workers. In summary, the traditional tunnel ventilation method has certain limitations and shortcomings in the process of tunnel advancement. Therefore, an innovative technical solution is needed to solve these problems, improve work efficiency and protect the health of workers. Summary of the invention

[0003] In view of the defects in the prior art, the purpose of the present invention is to provide a tunnel propulsion trolley with an integrated ventilation structure during the construction process. To achieve this goal, the present invention proposes a technical solution, which is characterized in that the device has an integrated design. In addition, the design of the present invention can also efficiently ventilate, remove dust and separate sewage, improve work efficiency and meet the construction needs of special construction scenes.

[0004] On the basis of the above technical scheme, the present invention relates to a propulsion trolley of an integrated tunnel ventilation structure, including an air supply fan, an exhaust fan, an air supply duct, an exhaust duct, a trolley, an air purifier, an air purification external unit, an exhaust fan, an exhaust duct, and a universal wheel. Three fans are arranged outside the tunnel entrance, including two large fans and a small fan, for providing power for air flow. A large fan and a small fan are used to supply air to the inside of the tunnel, and the other large fan is used for exhaust. The air supply fan and the exhaust fan are arranged at a certain distance to achieve clean and dirty diversion and avoid air flow interference. The air supply duct connects the inside and outside of the tunnel construction channel, and one end of the air supply duct is connected to the air supply fan. The air supply fan directly delivers air to the construction position inside the tunnel through the air supply duct. The duct is designed to be straight-through and is not connected to other devices to ensure the efficiency and stability of air supply. The small fan is specifically responsible for supplying air to the confined space. Exhaust fans are installed on the two arched fans of the trolley. One fan is used for dust removal before entering the site, and the other fan is used for dust removal after leaving the site. These exhaust fans are connected to the exhaust duct through connecting pipes to ensure that dust can be discharged in time. An air purifier is also installed inside the trolley. The fan near one end of the face draws the air in the tunnel into the air treatment device through the pipe, and then exhausts it after dust removal and filtration. All air purification external units are connected to the exhaust duct through connecting pipes. The exhausted hot air is extracted through the exhaust duct to avoid heat accumulation in the construction area. The trolley is equipped with universal wheels as a whole, which is convenient for moving between different construction areas, improving the flexibility and use efficiency of the equipment.

[0005] Compared with the prior art, the advantages of the present invention are:

[0006] 1. Integrated design: ventilation and dust removal equipment are integrated on one trolley, which reduces the space occupied by equipment and simplifies on-site layout and management.

[0007] 2. Efficient ventilation and dust removal: Through reasonable fan configuration and pipeline design, efficient ventilation and dust removal functions are achieved, ensuring the ventilation quality in the tunnel, improving the construction environment and improving construction efficiency.

[0008] 3. Clean and dirty flow separation: Through the reasonable arrangement of air supply fans and exhaust fans, clean and dirty flow separation is achieved to avoid air flow interference.

[0009] 4. Strong adaptability: The small fan supplies air to the confined space through an independent air supply duct, which can meet the needs of special construction scenarios.

[0010] 5. Flexible movement: The trolley is equipped with rollers to facilitate movement between different construction areas and improve the efficiency of equipment use. BRIEF DESCRIPTION OF THE DRAWINGS
