Description
【考案の詳細な説明】 産業上の利用分野 本考案は、人工樹を中央分離帯に配置または植設してな
る高速道路に関する。TECHNICAL FIELD The present invention relates to a highway in which artificial trees are placed or planted in a median strip.
従来技術 世界はいまモータリゼーション時代を迎え、自動車の数
は著しく増加している。わが国でも高速道路のある地点
でピーク時の自動車通過台数は１時間に902台であり、
当然これらの車から排気される排気ガスは膨大な量とな
り、道路沿い、特に中央分離帯に植栽された樹木は往復
車線の排気ガスをもろにうけて大きな被害をうけてい
る。Conventional Technology The world is now in the age of motorization, and the number of automobiles is increasing remarkably. Even in Japan, the number of cars passing through at the peak of an expressway is 902 per hour,
Naturally, the amount of exhaust gas emitted from these vehicles will be enormous, and trees planted along the road, especially in the median strip, will be greatly damaged by the exhaust gas from the two-way lane.
管理当局もこれらの被害地に対し対策に大童であるが、
なんといつても絶間なく受ける排気ガスが樹木の生理限
界をはるかに越えている。The management authorities are also big children to take measures against these damaged areas,
The exhaust gas that is constantly received exceeds the physiological limit of trees.
周知のごとく、中央分離帯は往復車線を分離するために
道路の中央に設けられたもので、中央分離帯植栽の目的
は、夜間操向時における対向車のヘットライトのクレア
防止、視線誘導、美観、さらに走行心理上の効果、即ち
対向車を遮蔽することによる安心感や緑の一般的な心理
的効果を期待している。即ち、道路植栽の機能として、
樹木（緑）は、道路というハードな人工構造物にたいし
て植物というソフトな自然物による修景が他の何ものに
もかえがたいということである。As is well known, the median strip is provided at the center of the road to separate the two lanes.The purpose of planting the median strip is to prevent the oncoming vehicle's headlight from clearing and guide the line of sight at night. It is expected to have an aesthetic effect and a driving psychological effect, that is, a sense of security and a general psychological effect of green by blocking an oncoming vehicle. That is, as a function of road planting,
A tree (green) means that a hard artificial structure such as a road is hard to replace with a landscape of soft natural objects such as plants.
考案が解決しようとする問題点 中央分離帯の樹種は、排気ガスや乾燥に耐え、病虫害が
少なく、枝葉密生し、刈り込みに耐える常緑樹であるこ
と、海岸に近いところでは潮風にたえること、積雪地で
は融雪剤にたえること、大量に入手しうることなど、き
びしい条件にあうことが必要である。Problems to be solved by the invention The tree species in the median strip are evergreen trees that can withstand exhaust gas and dryness, have little pest damage, dengue and vegetation, and can be trimmed. On the ground, it is necessary to meet severe conditions such as being able to use snow-melting agents and being available in large quantities.
本考案の目的は、上記の問題点を解決した中央分離帯を
提供することにある。An object of the present invention is to provide a median strip that solves the above problems.

は表層である。Means for Solving the Problems The constitution of the present invention for achieving the above object will be described with reference to FIG. 2 corresponding to the embodiment. In FIG. 2, the artificial tree 1 may be a plastic artificial tree or an aggregate thereof so as not to spoil the appearance. The root of the artificial tree 1 is fixed to a concrete block or flat plate 2 which is a support. Alternatively, in a factory or the like, an artificial tree is manufactured by fixing the root of the artificial tree 1 to a concrete block or a flat plate 2 which is a support base in advance. Then, the concrete block or flat plate 2 at the base of the artificial tree 1 is buried in the remaining soil 3 and planted in the median strip 4 of the expressway. 5
Is dark, 6 is roadbed, 7 is foundation, 8 is bonding layer, and 9
Is the surface layer.
植樹の形式は同一形状の樹木を一定間隔に並べた整形
式、ランダム式、または列植式としてもよい。The form of tree planting may be a well-formed type in which trees of the same shape are arranged at regular intervals, a random type, or a row type.

などの管理の手間がかからない。Action Since the driver's behavior on the highway is performed at a high speed close to 1100 km / h, the eye position of the driver's eyes is constant, the field of view is blurred within the frame of the windshield, gazing ahead, and necessary. Move the eyeballs accordingly and look at the road surface or road side. The landscape in front approaches at a fast speed, and flows to the rear on the left and right of the field of view. In this way, the correspondence with the landscape on the expressway changes moment by moment. Therefore, artificial trees cannot be distinguished from natural trees and are overlooked. And (1) the artificial tree does not die by exhaust gas, so it does not need to be replanted, (2) even if it is contaminated, it can be washed away by rainfall and the edges can be always maintained, (3) the artificial tree The construction cost for planting is low, and (4) there is no need to manage the soil, fertilizer, pruning, etc.

い。Effect According to the present invention, the light-shielding effect, the line of sight guidance, the aesthetics during the daytime are excellent, and the soft artificial landscape of the plant can be obtained for the hard artificial structure of the road, and it is unrelated to exhaust gas, dryness, pests, etc. . It is available in large quantities, is easy to install, and has low construction, maintenance, and repair costs due to accidents. It goes without saying that fertilization, soil, pruning and other management are unnecessary.
