随着四化建设需要,长期从事林区公路勘测和设计的工程技术人员,近年来除开进行林区公路勘测设计而外,不断走向了社会,进行厂矿公路、乡村公路和城镇道路的改建和扩建的勘测设计。我们去年在律寨公路的勘测中,该公路为沿河线,坡脚有一条农灌沟,沟帮已成为人行小路,沟的下侧紧接是河流。公路就要从这一地带穿过。其中有一段路除沟帮可供人行走之外,其余灌木很密,杂草高于人,选线视线不通,横坡陡峻。个别地段横坡大于90°,勘测技术人员和小工难于行走,甚至无法通过,布线、测量进度很慢,选线质量 With the need of the four modernizations, engineers and technicians who have long been engaged in the survey and design of forest roads have, in recent years, continued to make researches and developments in the roads and roads of factories and mines, in addition to carrying out surveying and designing of forest roads. Survey Design. In the survey of Luzhai Highway last year, the road was along the river and there was an agricultural irrigation ditch at the foot of the slope. The ditch help has become a pedestrian path. The lower side of the ditch is followed by the river. The road is going through this area. Among them, there is a section of road besides ditch help for people to walk, the rest of the shrubs are dense, weeds are higher than people, the line of sight is not clear, and steep slopes. The cross-slope of individual lots is greater than 90 °, the survey technicians and laborers are hard to walk or even unable to pass, the wiring is slow, the measurement progress is slow, the quality of line selection
