Embodiment

[0021] refer to Figure 1-2 , a dust-proof and ventilating device for tunnel construction, comprising a casing 1 and a ventilation pipe 2, the casing 1 is communicated with a water inlet pipe 5 and filled with water whose liquid level is at 3 / 4 height, and the ventilation pipe 2 runs through the casing 1 at the same time The inner walls on both sides of the housing 1 are respectively connected with a first branch pipe 3 and a second branch pipe 4. The nozzle heights of the first branch pipe 3 and the second branch pipe 4 are greater than the liquid level in the housing 1. The housing 1 A positioning ring 6 is floating in the liquid surface, the inner ring part of the positioning ring 6 is fixedly connected with a fixed film 7, and the bottom of the fixed film 7 is connected with an ultrasonic transducer;

[0022] The inner wall of the housing 1 is provided with an annular groove 8, the size of the annular groove 8 matches the positioning ring 6, and the side of the positioning...

Abstract

The invention discloses a dustproof ventilation device for tunnel construction. The device comprises a shell and a ventilation pipe; the shell communicates with a water inlet pipe and is filled with water with the liquid level at three-fourths height; the ventilation pipe penetrates through the inner walls of the two sides of the shell at the same time, and the parts, in the shell, of the ventilation pipe are provided with a first branch pipe and a second branch pipe in a communicating mode correspondingly, wherein the pipe orifice height of the first branch pipe and the pipe orifice height ofthe second branch pipe are both larger than the liquid level height in the shell; and positioning rings float in the liquid level in the shell, the inner ring parts of the positioning rings are fixedly connected with fixing films, and the bottoms of the fixing films are connected with ultrasonic transduction pieces. The device has the advantages that the branch channels are formed in the ventilation pipeline, so that atomized water generated in the shell is discharged under driving of positive-pressure air flow, which has the beneficial effects that the ventilation and dust removal are carried out at the same time, and compared with an existing water curtain dust remover, the device saves a high-pressure air pipeline and a water spraying pipeline which are additionally arranged.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a dust-proof and ventilating device for tunnel construction. Background technique [0002] A tunnel is an engineering building buried in the ground, and it is a form of human use of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mine tunnels, and military tunnels. [0003] In tunnel construction, especially in super long tunnel construction, good ventilation and dust prevention is an important measure to improve the construction environment in the tunnel and improve work efficiency. Ventilation and dust prevention mainly solve two problems. One is toxic gas, which mainly comes from Blasting gun smoke and exhaust gas from internal combustion machinery; the second is dust, which mainly comes from the dust raised by excavation, blasting and mechanical operations in the cave. In the prior art, wet dust is generally u...
