以往我們对隧洞工程都認为是技术性复杂,此較难作的工程,不敢做,也做的很少。經过水利高潮运动,在党的正确領导下,充分发揮了羣众的智慧和大胆創造的积极性,今年我区打28个隧洞,总長3914.5公尺,其中最長的433公尺,打破了不敢做的保守思想。另外从已打的隧洞看,所遇的地質情况也不一样,有粘土、石灰岩、紅砂石、頁岩、礫岩、石英岩、云母片岩等岩层。由于地質構造不同,因而,开凿隧洞的方法,也是多样化。茲將具体施工方法叙述如下,以供
In the past, we all thought that the tunnel project was technically complex. This is a harder project. We did not dare to do it and did very little. After the campaign of climactic movement, under the correct leadership of the party, it has given full play to the wisdom of the masses and the enthusiasm for bold creation. This year, the district hit 28 tunnels with a total length of 3914.5 meters, the longest of which was 433 meters and broke I did not dare to do conservative thinking. In addition, from the tunnel has been hit, the encountered geological conditions are not the same, there are clay, limestone, red sandstone, shale, conglomerate, quartzite, mica schist and other rock formations. Due to the different geological formations, the method of tunneling is also diversified. Specific construction methods will be described below, for
