我國對該技術(shù)的研究剛起步,目前,借鑒小木塊削制研究成果,開始對小木塊坪地加工技術(shù)進行全面研究。項目啟動以后,所開發(fā)的技術(shù)將迅速縮短我們和國際上的差距。2003年,東北林業(yè)大學馬巖教授邀請日本教授到中國來講學,相互交流木材小木塊坪地的加工技術(shù)。馬巖教授在小木塊削制的研究上發(fā)表了一些文章,對小木塊的加工精度已經(jīng)達到工業(yè)化要求,并利用這些小木塊鋪裝出實驗樣地,其研究已進入到實驗室研究的階段。
2.國外詳細情況
德國、美國和澳大利亞是最早開始研究小木塊坪地工藝與技術(shù)的國家,到20世紀末,德國和澳大利亞已經(jīng)形成小木塊坪地的理論和實驗室成果。德國于21世紀開始形成小木塊原料加工的技術(shù),以適應(yīng)小木塊工業(yè)的大批量和自動化生產(chǎn)的要求。自從Maier公司和德利斯頓大學的研究人員完成了小木塊坪地技術(shù)的應(yīng)用研究以后,Maier公司又開發(fā)出相關(guān)的工藝技術(shù),世界上眾多小木塊加工工業(yè)發(fā)達的國家紛紛在這些項目研究上與Maier公司進行商業(yè)聯(lián)合開發(fā)和學術(shù)交流,并在此基礎(chǔ)上取得了大量的研究與開發(fā)成果。僅僅幾年,圍繞小木塊坪地和小木塊加工新產(chǎn)品已經(jīng)開始進入實驗室研究,當今世界新型小木塊加工設(shè)備都運用了德國科學家的技術(shù)成果。小木塊坪地屬于新型小木塊加工技術(shù)在綠化方面的高科技產(chǎn)品,小木塊坪地也屬于新型小木塊加工技術(shù)的最先進加工技術(shù)的成果產(chǎn)品,這項加工技術(shù)已經(jīng)引起全世界的注意。現(xiàn)在,全世界已經(jīng)有幾家小木塊坪地研究單位。
德國也是最早實現(xiàn)小木塊坪地數(shù)控加工工業(yè)化實驗的國家。由于德國的小木塊機械工業(yè)是世界第一大產(chǎn)業(yè),因此,該國已經(jīng)將小木塊坪地工藝與技術(shù)應(yīng)用在世界范圍內(nèi)推廣。Maier公司在數(shù)控新型小木塊的開發(fā)上實力最強,每年他們都推出新的研究成果。
隨著數(shù)控技術(shù)不斷發(fā)展,現(xiàn)在已有許多數(shù)控鋸機,圓鋸機應(yīng)用廣泛,是木材機械加工中最基本的設(shè)備之一。
按照切削刀具的加工特征,圓鋸機可分為:縱鋸圓鋸機,橫截圓鋸機和萬能圓鋸機。若按工藝用途分則有:鋸解原木,在剖板材,裁邊等形式。而按鋸片數(shù)量分又有單鋸片,雙鋸片和多鋸片,等等。
木塊坪地的研究和開發(fā)的目的是基于城市綠化過程中,由于剪枝、間伐、枯木死樹處理等工序會產(chǎn)生大量的木質(zhì)廢料,這些木質(zhì)廢料在過去一直作為垃圾、燒柴、小木塊原料處理。由于城市燒柴的用量越來越少,小木塊應(yīng)用
的量也越來越少,實際這些廢料絕大多數(shù)都作為城市垃圾處理了。如果我們設(shè)計一套專用的設(shè)備,將這些廢料削成小木塊。采用專用的篩選設(shè)備將加工小木塊的碎料鋪在小木塊的下面,起到肥沃土壤的作用,使營林的全部廢物就地全部利用。
木塊坪地還具有保墑作用,會使生長在木塊坪地上的植物有充足的水分供應(yīng),達到促進植物生長的目的。木塊坪地的木材隔熱作用可以調(diào)節(jié)土壤的溫度和濕度,木塊坪地覆蓋了露在地表的塵土,實現(xiàn)防止這些塵土造成城市空氣污染的目的。在城市下大雨的時候,木塊坪地可以迅速地滲水,防止道路和綠地出現(xiàn)積水,起到調(diào)節(jié)城市排水的目的。木塊坪地美觀、調(diào)節(jié)氣候、廢物利用、促進植物生長,這些優(yōu)點決定了這項技術(shù)一旦推廣將產(chǎn)生巨大的經(jīng)濟效益和社會效益。
開發(fā)小木塊坪地綠化技術(shù)的最大意義是該技術(shù)的成本低、效益高。和草坪、灌木坪和花坪相比,其成本大幅度下降,因為它的原料成本幾乎沒有,這是草坪、灌木坪和花坪根本不能比擬的。該技術(shù)利用城市綠化部門無法處理的廢料,是經(jīng)濟效益和社會效益雙贏的項目,這是項目開發(fā)的必要性所在和開發(fā)的意義所在。國外十幾年前開始采用小木塊坪地綠化,我國至今沒有開展這項研究,因此,該技術(shù)研究屬于國內(nèi)首創(chuàng),是填補國內(nèi)空白和爭取國際先進水平的研究,具有重大的理論意義。
城市木塊坪地削塊設(shè)備是近幾年國際林業(yè)機械行業(yè)出現(xiàn)的最新產(chǎn)品。現(xiàn)在,只有美國和德國具備制造城市木塊坪地削塊設(shè)備和相應(yīng)的配套技術(shù)的能力。由于人們生活水平的提高,降低空氣污染和提高環(huán)境質(zhì)量的需求越來越高。國內(nèi)治理沙塵和綠化的任務(wù)日趨嚴重,這就對木塊坪地設(shè)備和相應(yīng)的配套技術(shù)的應(yīng)變能力要求越來越高。城市木塊坪地削塊設(shè)備和相應(yīng)的配套技術(shù)正是適應(yīng)了這個形式而誕生的高科技產(chǎn)品。城市木塊坪地削塊設(shè)備和相應(yīng)的配套技術(shù)是直接針對城市綠化營林加工需求的。

In accordance with the processing characteristics of cutting tools, circular saws can be divided into: vertical saw circular saw machine, circular saw machines and universal cross section saw machine. In terms of technology use in sub-rule include: sawing logs, in the profile control plates, cutting edge form. While the number of points have a single saw blade, dual-and multi-saw blades, and so on.
Wood Ping land for the purpose of research and development is based on urban greening process, due to pruning, thinning, dead wood, dead trees treatment process would produce large amounts of wood waste, wood waste, such as in the past has always been garbage, wood, small pieces of wood material handling. As the city less and less consumption of fuel wood, small pieces of wood volume applications, less and less, the actual majority of these wastes are part of the urban waste of the. If we design a special device, the fuel is whittled a small piece of wood. Use of dedicated screening equipment for scrap processing and small pieces of wood shop in the small wood below, playing the role of fertile soil, so that all the waste in situ silvicultural fully utilized.
Ping to block also has a role in preserving soil moisture will lead to the growth of plants in the wood on the ground floor there is sufficient water supply, to achieve the purpose of promoting plant growth. Insulated timber wood floor to the role of the soil can adjust the temperature and humidity, wood floor to cover the exposed on the surface of the dust, to achieve prevent them from dust caused by urban air pollution. When it rains heavily in the cities, wood floor to be quickly seepage of water, roads and green areas to prevent the emergence of stagnant water serve the purpose of regulating urban drainage. Wood floor to beauty, climate regulation, waste utilization, to promote plant growth, these advantages of the technology, once the decision will have a huge promotion of economic and social benefits.
Development of small pieces of wood floor in green technology, the greatest significance is the technology low cost, effective. And lawn, shrubs, and Fa Peng Ping, compared their costs have dropped significantly because of its raw material costs little, it is grass, shrubs, and Fa Peng Ping simply can not be compared. The technology sector can not handle the use of urban green waste, is a win-win economic and social benefits of the project, which is where the need for project development and development is all about. Abroad 10 years ago began to use small pieces of wood floor to Green, China has yet to carry out this study, therefore, the research part of national initiative is to fill the gaps and secure the international advanced level of study, has important theoretical significance.
Urban wood floor to cut a block device in recent years, the international forestry machinery industry appears the latest products. Now, only the United States and Germany, with manufacturing city wood floor to cut block devices and the corresponding supporting technology.
