Embodiment Construction
[0063] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0064] as attached Figure 1 to Figure 9 As shown, a press-in ventilation hose P guide device 100 for assisting tunnel construction is shown. The guide device 100 is divided into three parts: a guide structure 1 , a lift structure 2 and a fixed structure 3 from top to bottom.
[0065]The guide structure 1 includes a plurality of guide units 1a sequentially connected along the tunnel corner. In this embodiment, the number of guide units 1a is five. Each of the guide units 1a includes an arc-shaped guide plate 1a1 and an arc-shaped baffle plate 1a2. The arc-shaped guide plate 1a1 is a concave arc-shaped structure, which is used to place the ventilation hose P, and forms a semi-surrounding of the ventilation hose P. The arc-shaped guide plate ...

The invention discloses a press-in type ventilation hose guiding device for assisting tunnel construction, comprising a guiding structure, a lifting structure for adjusting the height of the guiding structure, and a fixing structure for fixing the guiding structure; multiple guide units, each guide unit includes an arc-shaped guide plate and an arc-shaped baffle; the arc-shaped guide plate is a concave arc-shaped structure for placing ventilation hoses; the arc-shaped baffle It is connected to the outer end of the circular arc guide plate; an expansion joint is formed between two adjacent guide units, and a plurality of angle adjustment devices are arranged between the two adjacent guide units along the expansion joint to adjust the expansion joint by The inner end of the expansion joint points to the width of the outer end of the expansion joint along a circular arc, so as to adjust the turning angle of the guide device. The present invention guides the hose to different angles by means of vertical support and semi-envelope guidance, thereby reducing the wrinkle deformation and ventilation resistance caused by the suspension method.
Description
technical field [0001] The invention relates to tunnel construction ventilation technology, in particular to a press-in ventilation hose guide device for assisting tunnel construction. Background technique [0002] At present, the commonly used construction method for tunnels is the new Austrian method. The tunnel face often requires measures such as blasting and bolting and spraying support. In addition, the emission of slag-discharged automobile exhaust seriously reduces the air quality in the tunnel and affects normal construction. The progress and the safety of the staff in the tunnel; and the tunnel construction period is long, the electricity cost is relatively large, and equipment costs account for a large proportion of investment, so reasonable construction ventilation schemes and energy-saving measures must be adopted. [0003] Ventilation methods for tunnel construction mainly include press-in type, exhaust type, hybrid type, and roadway type. Most of these constru...
