Description

Tunnel lining trolley with ventilation pipe capable of passing smoothly

Technical Field

Background

In the tunnel construction process, in order to supply fresh air to the inside of the tunnel, harmful substances such as harmful gas, steam, dust and gun smoke are removed, the temperature of the air in the tunnel, relative humidity and flow rate meet the construction requirements such as specified standards, the tunnel is constructed and ventilated to the inside of the tunnel in a combined mode of a ventilator and a ventilation pipeline, especially in the construction process of a long tunnel and an extra-long tunnel, the ventilation in the tunnel construction plays a crucial decision role in the aspect of overall construction organization, and meanwhile, in the unfavorable geological construction of special toxic and harmful gases such as high gas and hydrogen sulfide, the ventilation in the tunnel construction is an important factor in the aspect of safety risk management and control. The tunnel construction ventilation is not only just the selection and the use of equipment, but also the more restriction factor is the level of ventilation management, wherein the ventilation management mainly refers to the management of ventilation pipelines, and the ventilation management comprises the aspects of the straightness of the pipelines, the damage of the pipelines, the materials of the pipelines (the air leakage rate of hundred meters, the ventilation resistance) and the like. In the secondary lining construction process of the tunnel, the tunnel lining trolley is special equipment which must be used in the secondary lining in the tunnel construction process and is used for concrete lining construction of the inner wall of the tunnel.

Referring to fig. 1 to 4, a conventional ventilation pipe 13 is embedded at a hanging point 16 at a primary support or a secondary lining on a construction site of a tunnel 11, and the embedded hanging point 16 is hooked on a hook 14 of the ventilation pipe 13 through a steel wire 15, so that the ventilation pipe 13 is arranged along a side wall or a vault of the tunnel 11, wherein a place which has a particularly large influence on ventilation effect is a place where the ventilation pipe 13 passes through a tunnel lining trolley. The tunnel lining trolley belongs to special equipment for construction advancing at any time, so that the hanging scheme of the overlapped section of the ventilation pipe 13 and the tunnel lining trolley and the side wall or the vault of the tunnel 11 is adjusted when the tunnel lining trolley moves every time, and the operation can be carried out only by stopping wind (the wind pressure in the ventilation pipe 13 is higher during normal ventilation, the whole ventilation pipe 13 is in a high-pressure bulging state, so that the ventilation pipe 13 becomes soft after the wind is stopped, and the hanging adjustment can be carried out) during each adjustment, so that the ventilation effect of the tunnel 11 construction is influenced, particularly in the unfavorable geological construction of special toxic and harmful gases such as high gas, hydrogen sulfide and the like, the wind stopping of the ventilation pipe 13 inevitably causes the rapid increase of safety risks, and serious safety production accidents are easily caused.

In addition, when the ventilation pipe 13 passes through the tunnel lining trolley, the ventilation pipe 13 has the fold sections 131 at the two ends of the tunnel lining trolley, so that the ventilation section is changed, the local wind resistance of the ventilation pipe 13 is obviously increased, the wind loss is high, and the ventilation effect of the tunnel 11 construction is influenced. And, with the increase of the construction frequency, the breakage rate of the bent section 131 existing after the ventilation pipe 13 passes through the tunnel lining trolley is extremely high, which further causes the increase of the air leakage rate and affects the ventilation effect of the tunnel 11 construction.

In addition, the diameter of the through hole for the ventilation pipe 13 to pass through of the existing tunnel lining trolley is matched with the diameter of the ventilation pipe 13, the internal wind pressure of the ventilation pipe 13 is high when the ventilation pipe 13 is ventilated, the ventilation pipe 13 is in a high-pressure bulging state as a whole, even if wind stopping operation is carried out when the tunnel lining trolley moves each time, the pipe wall of the ventilation pipe 13 has an elastic recovery fatigue phenomenon, so that the pipe wall of the ventilation pipe 13 is difficult to recover to the original diameter, and therefore resistance friction exists between the ventilation pipe 13 and the through hole of the tunnel lining trolley, and the bottom of the ventilation pipe 13 and the through hole of the tunnel lining trolley also have resistance friction under the action of self gravity of the ventilation pipe 13, and therefore the tunnel lining trolley moves relative to the ventilation pipe 13 insufficiently smoothly or even is blocked.
