山区公路两侧的爆破造林

AFFORESTATION ON TWO SIDES OF A HIGHWAY IN MOUNTAIN AREA BY BLASTING METHOD

利用钻孔爆破方法和公路运输的便利条件在山区公路两侧植树造林,能够大大提高大规模造林的效率。本文概述了山区公路两侧爆破造林的优越性,详细介绍了爆破开挖树坑的施工方法、药量计算和装药结构;同时讨论了不同形式的路堑坡面上的不同布孔方式。文中还谈到了有关山区公路两侧大规模爆破造林的经验和体会。

Using drilling-and-blasting method and convenient highway transportation for afforestation on two sides of highway in mountain area,the efficiency of large-scale afforestation can be greatly raised.In this paper,the advantages of afforestation by blasting on two sides of highway are outlined,the blasting digging of tree pits,calculation of charge mass and charging structure are expatiated.At the same time,different blasthole patterns for different modes of cut slopes are discussed.Also,author's experience about large-scale afforestation by blasting on two sides of highway in mountain area is presented.
