Description

Tunnel shaft light steel is dustproof to fall and is fallen isolation canopy of making an uproar

Technical Field

The utility model relates to a tunnel shaft light steel is dustproof to fall and is fallen isolation canopy of making an uproar belongs to construction technical field.

Background

In the current urban subway construction process, the subway tunnel is mainly constructed by a mine method, a shield method and an open cut method, but along with the open cut method, the underground tunnel is less excavated, but the mine method construction process is widely applied. In the construction of urban subway tunnels and mines, tunnel excavation is often carried out by adopting a tunnel shaft construction process, and blasting construction is mostly adopted in the tunnel shaft in the excavation construction process. With the continuous improvement of national requirements on environmental control and the continuous improvement of urban civilized construction conditions, the control conditions for dust prevention and noise reduction in the construction process of the tunnel shaft are more rigorous. On the other hand, subway construction usually needs to pass through a busy section and a concentrated section of a residential area of a city, so that how to ensure that people are not disturbed, dust pollution is reduced, the safety of surrounding buildings, pedestrians and residents is ensured and the like in the construction process of the tunnel shaft is the primary index for smooth construction of the tunnel. According to the construction experience in the past, tunnel shaft construction is often open-air construction, in time adopts the shaft to keep apart the preventive measure, because the input of shaft isolation canopy is great, give sound insulation and fall the relatively poor reason such as making an uproar, at the in-process of construction, continuous complaint that suffers from the resident of periphery, because the dust fall effect is relatively poor, can not reach the requirement of civilized construction, and suffer corresponding penalty. But with the continuous improvement of the requirements of the project on the construction period, the construction quality, the construction progress and the site civilized construction, after the tunnel shaft light steel dustproof noise reduction isolation shed is adopted for construction on the shaft site, statistical analysis is carried out on the quality and civilization degree of peripheral residents, commercial tenants, site construction workers, peripheral pedestrians and site construction, after the isolation shed is used for construction, the problems can be well solved, for example, the prior vertical shaft isolation shed is used, the prior materials of the surrounding framework materials of the isolation shed are uneconomical, the sound insulation effect of the surrounding sealing materials is poor, the lighting and ventilation effects of skylight and roof of the isolation shed are poor, the site construction temperature in the isolation shed is higher, the typhoon resistance of the isolation shed is poor and the like, meanwhile, the materials of the isolation shed can not be reused, the dust-proof capability in the field construction process is poor, and the field civilized construction is poor. In order to reduce and solve the problems, the dustproof noise reduction, ventilation, lighting and cooling of field construction are improved, and economic loss caused by waste is reduced. Through experiment and on-site actual construction, the tunnel shaft light steel dustproof noise reduction isolation shed is installed above the shaft, the problems generated by the above can be well solved and reduced, the on-site construction efficiency can be well improved by the tunnel shaft light steel dustproof noise reduction isolation shed, the on-site installation civilized construction degree of the isolation shed is high, the on-site installation operability is high, the construction is scientific, the machining efficiency is high, the on-site installation construction speed is high, each part manufacturer professionally processes, the on-site installation is realized, the construction quality is high, the on-site civilized construction is improved, meanwhile, the on-site dismantling is convenient, the reutilization can be maximized, and the economic investment is saved.
