Description

Excavators used to construct pipeline-style passages

technical field

The present invention relates to excavation construction machines, and more particularly to excavators for constructing pipeline-type passages.

Background technique

At present, in response to sudden disasters caused by mine collapses, there are three main ways to carry out rescue: one is to clean up and reinforce the collapsed site, and open up emergency rescue channels. This rescue method is usually used when the collapsed area is not large. Due to the limitation of the site conditions, it is generally inconvenient to use large-scale professional rescue equipment. Carry out cleaning and reinforcement, and open up emergency rescue passages. The emergency rescue passages are often constructed in the form of wooden pillars and padding materials. The advantages are short preparation time and good mobility; however, it is difficult to clean and reinforce the site, and the degree of mechanization is not high. Large, the rescue efficiency is low, and there is a risk of secondary collapse, and the safety performance is not good. The second is to dig another rescue channel from the inside of the mine to bypass the collapse site. This rescue method is usually used when there are many curves, the collapse site is complicated, and it is difficult to clean up and reinforce the collapse site. Professional excavation equipment (such as mining rigs, roadheaders, etc.) is often used to open emergency rescue channels. The safety performance is relatively good for cleaning and strengthening the collapsed site; however, it is relatively difficult to excavate the rescue channel, the preparation time is long, the amount of work is large, and the rescue efficiency is not high. The trapped people get in touch and provide the most basic supplies (such as: water, food, etc.). The third is to excavate emergency rescue channels vertically from the surface to avoid the collapse site. This rescue method is usually used when the collapsed area is not particularly deep from the ground surface. Its advantages are that the ground operation space is large, and large-scale and efficient professional excavation equipment (such as: high-efficiency deep-hole drilling equipment, etc.) can be used, and the excavation efficiency is high and safe. Good performance; however, due to the high degree of equipment specialization, long preparation time, relatively deep excavation depth, large engineering volume, and precise positioning, otherwise there is a risk of deviating from the actual mine and requiring multiple excavations, and the rescue efficiency is not high. Drilling is used to excavate rescue supply holes, which are mainly used to get in touch with the trapped people and provide the most basic supplies (such as: water, food, etc.). If it is possible not to clean up and reinforce the mine collapse site, but to directly build a pipeline-type emergency rescue channel through the collapse site directly from the collapse site, the rescue efficiency will be greatly improved. However, to realize this plan, professional excavators must be used for excavation, and professional supporting rescue equipment must be used. However, the existing multi-bucket excavators, wheel excavators, shield machines and other equipment are mainly designed for open-air excavation. , Excavating large tunnels, culverts, etc. as the application background, all belong to large-scale excavating equipment, limited by their structure and excavation methods, they cannot meet the requirements of excavating into pipeline emergency rescue pipelines.
