Abstract

The invention discloses a double-hole road tunnel construction ventilating system comprising an air feed roadway and an air return roadway. The front ends of the air feed roadway and the air return roadway are excavating faces, the front sections of the air feed roadway and the air return roadway communicate with each other through a front-section transverse passage, and at least one middle-section transverse passage is formed between the front-section transverse passage and tunnel holes and connected between the air feed roadway and the air return roadway in a communicating mode. The system further comprises an environment monitoring unit for collecting the environment data in tunnels, a ventilating unit for ventilating in the tunnels and an automatic control unit for controlling the ventilating unit to work. The ventilating unit comprises an air feed machine set arranged in the air feed roadway, an air draft machine set arranged in the air return roadway and air blow machine sets which are arranged in the front-section transverse passage and the middle-section transverse passage and face the air return roadway. The automatic control unit comprises a fuzzy controller, a PLC and a draught fan adjusting controller which are sequentially connected. According to the double-hole road tunnel construction ventilating system, the problem that an existing long-large tunnel is low in ventilating automation degree and low in ventilating efficiency can be solved.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a construction ventilation system for a double-hole highway tunnel. Background technique [0002] At present, with the rapid development of transportation, more and more highways, railways and long underwater tunnels are being constructed, and these projects are often the control projects of the entire project. The main reason is that the construction period is long and the construction environment Poor, one-way excavation takes a long time during construction; besides the pollutants near the face of the tunnel are difficult to discharge, it will bring secondary pollution to the construction area behind the tunnel, seriously affecting the construction progress of the tunnel project and the health of workers ; Especially in the plateau area, there is still insufficient oxygen near the tunnel face, which leads to a decrease in the efficiency of construction equipment, and workers...
