铁路斜井的使用期短,在选择提升容器和出碴方式时要考虑到工程数量少、设备简单、投产快、使用方便、安全等因素。以往铁路斜井施工多沿用冶金、煤炭系统的经验。近年来由于大型施工机械在铁路长大隧道的采用,在选择提升容器和出碴方式时,除应考虑铁路斜井的上述特点外,提升容器、出碴能力的配备还应满足大型机械设备施工的需要。为此我们提出采用大型侧卸式矿车井口斜坡不摘钩卸碴方案(以下简称本方案)。井口不摘钩卸碴,比串车、大型矿车提升在井口平车场摘挂钩安全,减少了井口溜车的危险,可省去大型矿车由井口至固定翻车设备间的牵引设备。井下运输和斜井提升用同一容器,可省去胶带运输机、箕斗提升在井下需配其它车辆的转载工序,可省翻碴、破碎、碴仓、卸碴绕道、卸碴洞室和由隧道底进入井底碴仓的斜井长度。和内燃车辆直接出碴相比,要求的通风量小,可避免因内燃车辆爬坡能力受限而增加的斜井长度,总的造价少。本方案能满足大型装载设备装碴的需要和施工进度快,要求提升能力大的需要。本文介绍了井口斜坡纵断面设计、大型侧卸式矿车的选型、翻车设备、转碴设备和栈桥设计等要点。本方案在大秦铁路军都山隧道2(?)斜井首次应用后,很快便突破了斜井工区双线隧道单工作面百米成洞大关。本方案的特点在实践中得到了证实,使用效果良好,可供铁路斜井机械化施工和类似条件的公路、输水隧洞参考使用。
The service life of railway inclined shafts is short. When choosing to upgrade containers and ballasting methods, it is necessary to take into account such factors as less number of works, simple equipment, quick commissioning, ease of use and safety. In the past, many railway inclined shaft construction followed the metallurgical and coal system experience. In recent years, due to the adoption of large-scale construction machinery in the long tunnels of the railway, when choosing to upgrade the containers and ballasting methods, in addition to considering the above characteristics of railway inclined shafts, the equipment for lifting containers and ballasting capacity should also meet the requirements for construction of large-scale machinery and equipment Need. To this end, we propose to adopt a large side dump truck wellhead slope without picking hook unloading ballast program (hereinafter referred to as the program). Wellhead unloading hook unloading ballast, than the series cars, large-scale mining car lift hooks in the wellhead Pingdian safety, reducing the danger of well head slipped, eliminating the need for a large tub from the wellhead to the fixed roll-over equipment traction equipment. Underground transport and inclined shaft to enhance the same container, eliminating the tape conveyor, skip upgrade to be equipped with other vehicles in the reloading process, can turn over ballast, crushing, ballast storage, unloading ballast bypass, unloading ballast chamber and tunnel The bottom of the shaft into the bottom of the pit incineration pit length. Compared with the direct ballast of internal combustion vehicles, the required ventilation is small, and the length of inclined shafts increased due to limited climbing ability of the internal combustion vehicle can be avoided, so the total cost is small. The program can meet the needs of large-scale loading equipment ballast and construction progress quickly, requiring large capacity needs. This article introduces the design of wellhead slope profile, the selection of large side dump trucks, roll over equipment, ballast equipment and trestle design and other points. After the first application of the inclined shaft 2 (?) In the Jun Dashan Tunnel of Daqin Railway, the program quickly broke through the 100-meter hole mark in the single face of a double-track tunnel in the inclined shaft area. The characteristics of this program have been verified in practice, with good results, for railways mechanized construction and similar conditions of highway, water tunnel reference to use.
