Description
本創作係關於一種水洗式高爐渣用在製作農田便道鋪面以及農田溝渠鋪面之用途以及該農田便道鋪面與農田溝渠鋪面。 This creation is about the use of a washed blast furnace slag for the production of farmland pavements and farmland ditch pavements, as well as the pavement of farmland pavements and farmland ditch.
如圖3所示，目前農田便道6是於農田7四周或農田7中，以築高的土堤而形成；然而，該土堤為泥土所建構而成，因此十分容易生長雜草，所以使得老鼠、蛇類容易躲藏在其中，其中老鼠則會挖洞造成土堤的破損，而蛇類會危害到農夫的生命安全，因此常需花費額外的成本來去除雜草或噴灑除草劑，以維護該土堤的環境；然而在噴灑除草劑時，該殘留的除草劑會汙染該土堤周圍的農田土壤而破壞農田7的生態，並使得作物受殘留的除草劑所汙染，而有影響人體健康之風險；且該土堤在下雨時會因雨水的滲入而變得泥濘，使得耕作車輛行走顛頗，甚至陷於泥濘中而無法動彈。因此，為避免上述缺點，許多農田便道6遂改以鋼筋水泥來建造。 As shown in Fig. 3, the farmland access road 6 is formed in the farmland 7 or in the farmland 7 to build a high earth embankment; however, the earth embankment is constructed of soil, so it is easy to grow weeds, so Rats and snakes are easy to hide in, and the rats will dig holes to cause damage to the earth embankment, and snakes will endanger the safety of farmers. Therefore, it is often necessary to spend extra cost to remove weeds or spray herbicides to maintain The environment of the earth embankment; however, when the herbicide is sprayed, the residual herbicide will contaminate the farmland soil around the earth embankment and destroy the ecology of the farmland 7, and cause the crop to be contaminated by residual herbicides, which may affect human health. The risk is that the earthen embankment will become muddy when it rains, causing the farming vehicle to walk upside down and even get stuck in the mud and unable to move. Therefore, in order to avoid the above shortcomings, many farmland roads 6 were tamper-built with reinforced concrete.
然而，利用鋼筋水泥來建造農田便道6，在興建成本上對農夫來說是十分昂貴的，而且興建時間很長；再者，生產水泥之過程係需要消耗大量能源，並且會產生廢熱及二氧化碳，則造成環境的負擔；而當需要將鋼筋水 泥建造的農田便道6拆除時，例如重新規劃農田7的大小時，農田便道6即需要拆除，由於鋼筋水泥建造的農田便道6係具有相當的結構強度，係需要使用大型的拆除機具才能拆除，則相當不便利且須耗費大量時間及成本，並且，拆除後而產生的鋼筋水泥廢棄物，係無法回收進而造成環境的負擔。 However, the use of reinforced concrete to construct farmland access roads 6 is very expensive for farmers and long-term construction time. Moreover, the process of producing cement consumes a lot of energy and generates waste heat and carbon dioxide. Causing environmental burden; when it is needed to rebar When the mud-constructed farmland road 6 is demolished, for example, when the size of the farmland 7 is re-planned, the farmland roadway 6 needs to be dismantled. The 6-series farmland roadway constructed by reinforced concrete has considerable structural strength, which requires the use of large-scale demolition tools to be removed. It is quite inconvenient and requires a lot of time and cost, and the reinforced concrete waste generated after the removal is not recyclable and causes an environmental burden.
而農田溝渠8則係於農田7四周或農田7中，挖除一定的土壤以形成農田溝渠8，然而，由於農田溝渠8之壁面以及底面均係為泥土，因此仍會有雜草生長或是蛇鼠躲藏於其中的問題產生，且農田溝渠8中田水的流動亦會使得農田溝渠8的壁面泥土鬆動而滑落至底面，將導致農田溝渠8漸漸被填平而需要重新挖設；然而，如前所述，若利用鋼筋水泥來補強農田溝渠8之壁面與底面，其建造成本太高、興建時間過長，且不論是建造或是拆除後都會造成環境的負擔。 The farmland ditch 8 is tied to the farmland 7 or the farmland 7 to excavate a certain amount of soil to form the farmland ditch 8. However, since the wall surface and the bottom surface of the farm ditch 8 are soiled, there is still weed growth or The problem of the snake and the rat hiding in it arises, and the flow of the field water in the farmland ditch 8 will also cause the soil on the wall of the farmland ditch 8 to loosen and slide down to the bottom surface, which will cause the farmland ditch 8 to be gradually filled and need to be re-excavated; however, As mentioned above, if reinforced concrete is used to reinforce the wall and bottom of the farm ditch 8, the construction cost is too high, the construction time is too long, and the environmental burden will be caused whether it is built or removed.
本創作為改善或減輕前述問題，係提供一種水洗式高爐渣用在製作農田便道鋪面以及農田溝渠鋪面之用途，其包含：以含細料級以下尺寸的水洗式高爐渣製作農田便道鋪面或農田溝渠鋪面；其中，該含細料級以下尺寸的水洗式高爐渣係將高爐渣水洗後成為水洗式高爐渣的泥水，再將水洗式高爐渣的泥水沉降分離後獲得。 In order to improve or alleviate the aforementioned problems, the present invention provides a water-washed blast furnace slag for use in making farmland pavement and farmland ditch pavement, which comprises: making farmland pavement or farmland with water-washed blast furnace slag having a size below fine grade The ditch pavement; wherein the water-washing blast furnace slag containing the fine material grade is obtained by washing the blast furnace slag into muddy water of the water-washed blast furnace slag, and then separating and separating the muddy water of the water-washed blast furnace slag.
又為了達成前述目的，本創作又提供一種水洗 式高爐渣製作的農田便道鋪面以及一種農田溝渠鋪面，其皆係以含細料級以下尺寸的水洗式高爐渣所製成，含細料級以下尺寸的水洗式高爐渣之組成包含一氧化鈣(CaO)、二氧化矽(SiO2)和三氧化二鋁(Al2O3)，且其粒徑尺寸為1毫米以下。 In order to achieve the above objectives, the present invention also provides a farmland pavement pavement made of water-washed blast furnace slag and a farmland ditch pavement, which are all made of water-washed blast furnace slag containing a size below the fine material grade, including fine material grade below. The composition of the water-washed blast furnace slag comprises calcium oxide (CaO), cerium oxide (SiO 2 ) and aluminum oxide (Al 2 O 3 ), and has a particle size of 1 mm or less.
較佳的是，該含細料級以下尺寸的水洗式高爐渣係將高爐渣水洗後成為水洗式高爐渣的泥水，再將水洗式高爐渣的泥水沉降分離後獲得的步驟係包含，由煉鋼廠之高爐中取得的高爐渣經水洗篩分機篩選出30mm以上、12至30mm、8至12mm以及8mm以下之四種尺寸範圍的水洗式高爐渣的泥水。 Preferably, the water-washing blast furnace slag having a size below the fine material grade is obtained by washing the blast furnace slag into muddy water of the water-washed blast furnace slag, and then separating and removing the muddy water of the water-washed blast furnace slag, comprising The blast furnace slag obtained in the blast furnace of the steel plant is screened by the water washing sifter for the muddy water of the blast furnace slag of the four size ranges of 30 mm or more, 12 to 30 mm, 8 to 12 mm and 8 mm or less.
各尺寸範圍之水洗式高爐渣的泥水接著透過洗砂機水洗以去除其中的沙，再經過磁選機將其中含鐵的殘鋼篩選出來後置於沉降池中沉降分離。 The muddy water of each size range of the washed blast furnace slag is then washed by a sand washing machine to remove sand therein, and then the iron-containing residual steel is screened by a magnetic separator and placed in a sedimentation tank for sedimentation and separation.
沉降分離係於沉降池中立一隔板，隔板之高度係低於沉降池之周壁，並藉由強力幫浦的輔助，使得部分泥水於隔板之前就沉澱下來，此部分於隔板之前就沉澱下來之泥水即係為含細料級以上尺寸之水洗式高爐渣，而其餘部分未於隔板之前沉澱之泥水，其尺寸更小，故繼續越過隔板而沉降在隔板之後，此部分未於隔板之前沉澱則係為含細料級以下尺寸的水洗式高爐渣。 The sedimentation separation is in the middle of the sedimentation tank, the height of the partition is lower than the peripheral wall of the sedimentation tank, and with the aid of the powerful pump, part of the mud water is precipitated before the partition, and this part is precipitated before the partition. The muddy water is the water-washed blast furnace slag containing the finer grade or above, and the remaining part of the muddy water which is not precipitated before the separator is smaller in size, so it continues to pass over the separator and settles behind the separator. Precipitation before the separator is a water-washed blast furnace slag containing a size below the fine grade.
除上述含細料級以下尺寸的水洗式高爐渣的獲得方式外，台灣專利I374192與I400335所提及的獲得方式亦合併於本案做為參考；然而，本創作並不侷限在上述方法所獲得含細料級以下尺寸的水洗式高爐渣，而是能 夠利用任何方法或裝置所製造的含細料級以下尺寸的水洗式高爐渣，只要是將水洗式高爐渣用在製作農田便道鋪面和農田溝渠鋪面的用途皆屬於本創作的範疇。 In addition to the above-mentioned methods for obtaining water-washed blast furnace slag containing fine-grained grades, the methods of obtaining mentioned in Taiwan Patent No. I374192 and I400335 are also incorporated herein by reference; however, the present invention is not limited to the above-mentioned methods. Water-washed blast furnace slag below the fine grade level, but The use of any method or apparatus for the manufacture of water-washed blast furnace slags having a size below the fine material level is within the scope of this creation as long as the use of the water-washed blast furnace slag for the production of farmland pavement and farmland ditch pavement.
較佳的是，沉降在隔板之後的含細料級以下尺寸的水洗式高爐渣係被挖出後置於廠房內自然乾燥至一定程度並仍保有水份，其中，乾燥的程度可依需求而調整。 Preferably, the water-washed blast furnace slag having a size below the fine fraction after being settled in the separator is excavated and placed in the factory to be naturally dried to a certain extent and still retains moisture, wherein the degree of drying can be determined according to requirements. And adjust.
較佳的是，含細料級以下尺寸的水洗式高爐渣自然乾燥後即可運送至預定鋪設之地點，並鋪設於農田便道之表面或農田溝渠之壁面和底面，再以機械(怪手、鏟車或小型壓路機等)或人工的方式抹平並施以外力使其緊實，最後藉由日曬使得含細料級以下尺寸的水洗式高爐渣完全乾燥並且膠結固化，即完成農田便道鋪面或農田溝渠鋪面之鋪設。 Preferably, the water-washed blast furnace slag having a size below the fine material level is naturally dried and then transported to a predetermined laying place, and laid on the surface of the farmland road or the wall and the bottom surface of the farmland ditch, and then mechanically (grotesque, (Forklift or small road roller, etc.) or artificially smooth and apply external force to make it compact. Finally, the water-washed blast furnace slag containing the fine material grade is completely dried and cemented by sun exposure, that is, the farmland pavement is completed. Or the laying of farmland ditch pavement.
另擇的是，其係於一農田溝渠內係裝設一水管，含細料級以下尺寸的水洗式高爐渣製作之農田溝渠鋪面係鋪設於該水管之上。 Alternatively, it is installed in a farmland ditch to install a water pipe, and the farmland ditch pavement made of water-washed blast furnace slag having a size below the fine material level is laid on the water pipe.
因現有之水洗式高爐渣係用於肥料或水泥添加物，其需先透過高熱能將現有之水洗式高爐渣乾燥後再經粉碎研磨乾式處理成粉末細料，故需要耗費大量能源；而本創作之含細料級以下尺寸的水洗式高爐渣係用於製作農田便道鋪面和農田溝渠鋪面，其自然乾燥時所保有之水份對於鋪面鋪設是有利的，其可避免運送途中該含細料級以下尺寸的水洗式高爐渣隨風飛散造成空氣汙染，而乾燥亦採自然乾燥可大幅降低能源的利用，十分符合經濟效益。 Because the existing water-washing blast furnace slag is used for fertilizer or cement additives, it needs to dry the existing water-washed blast furnace slag through high heat energy and then dry-process it into powder fine material by pulverization and grinding, so it requires a lot of energy; The water-washing blast furnace slag containing the fine-grained size is used to make farmland pavement and farmland ditch pavement. The water retained during natural drying is beneficial for paving, which avoids the fine material during transportation. The water-washing blast furnace slag of the following size is caused by air pollution, and the drying and natural drying can greatly reduce the energy utilization, which is very economical.
較佳的是，水洗式高爐渣的泥水中的成分係包 含一氧化鈣、二氧化矽和三氧化二鋁，其於乾燥後具有膠結之特性；因此當將含細料級以下尺寸的水洗式高爐渣傾倒並披覆在鋪面預定興建之處，並將其抹平，經由日曬曬乾水分後使其中之一氧化鈣、二氧化矽和三氧化二鋁膠結固化即可形成鋪面，因此製程簡單，無須耗費多餘的能量和經費。 Preferably, the component of the muddy water of the blast furnace slag is Containing calcium oxide, cerium oxide and aluminum oxide, which have a cementitious property after drying; therefore, when the blast furnace slag containing the size below the fine grade is poured and covered, it is planned to be built in the pavement, and It is smoothed, and after drying the water through the sun, one of the calcium oxide, the cerium oxide and the aluminum oxide is solidified to form a paving surface, so the process is simple, and no extra energy and expense are required.
較佳的是，含細料級以下尺寸的水洗式高爐渣在潮濕時結構鬆軟，而一但乾燥膠結固化後就相當密實，因此在鋪設含細料級以下尺寸的水洗式高爐渣製作成之農田便道鋪面或農田溝渠鋪面於農田便道或農田溝渠後，農田便道鋪面或農田溝渠鋪面將可以提高保護農田便道或農田溝渠之強度，使農田便道或農田溝渠不會長草、蛇無法隱藏於其中，亦不會有田鼠挖洞而造成土壤破損的問題，更不需以人工或除草劑去除雜草，則不會有人力耗費及除草劑汙染農田生態及作物的問題。 Preferably, the water-washed blast furnace slag having a size below the fine material grade has a soft structure when wet, and is relatively dense after the dry cementation is solidified, so that it is prepared by laying a water-washed blast furnace slag having a size below the fine material grade. After the farmland pavement or farmland ditch is paved in farmland access roads or farmland ditch, the farmland pavement or farmland ditch pavement will enhance the strength of protecting farmland access roads or farmland ditches, so that farmland access roads or farmland ditches will not be able to hide grass or snakes. There will be no problem of soil damage caused by burrowing holes, and there is no need to remove weeds by manpower or herbicides. There will be no manpower and herbicide pollution of farmland ecology and crops.
再者，由於含細料級以下尺寸的水洗式高爐渣，其於乾燥膠結固化後就相當密實，因此於下雨時雨水無法滲入由含細料級以下尺寸的水洗式高爐渣所製得的農田便道鋪面，亦不會使得農田便道變得泥濘，令耕作車輛行走平穩，更不會有陷於泥濘中而無法動彈之情形發生。 Furthermore, since the water-washed blast furnace slag having a size below the fine material grade is solidified after being dried and solidified, the rainwater cannot penetrate into the water-washed blast furnace slag having a size below the fine material level when it rains. The pavement of farmland will not make the farmland roads muddy, so that the farming vehicles will be stable and will not be trapped in the mud and unable to move.
此外，本創作之含細料級以下尺寸的水洗式高爐渣係為再生物資，其相較於水泥而言係具有低成本及環保之優點；而當需要將含細料級以下尺寸的水洗式高爐渣製作的農田便道鋪面或農田溝渠鋪面拆除時，由於其原料係細料級以下尺寸的水洗式高爐渣，令其相較於鋼筋水泥 建造的農田便道而言具有較低的結構強度，而便於破碎拆除則可節省時間及成本；並且，破碎拆除後產生的農田便道鋪面塊或農田溝渠鋪面塊係可進一步壓碎成小尺寸直接與農田土壤混合，而作為土壤改質劑使用，相當環保。 In addition, the water-washed blast furnace slag of the size below the fine material grade is re-biological, which has the advantages of low cost and environmental protection compared with cement; and when it is necessary to wash the water with the size below the fine material grade When the farmland pavement or farmland ditch pavement made by blast furnace slag is removed, the raw material is washed with blast furnace slag below the fine grade, so that it is compared with reinforced concrete. The constructed farmland access road has lower structural strength, and the easy to break and dismantle can save time and cost; and the farmland pavement block or farmland ditch pavement block generated after crushing and dismantling can be further crushed into small size directly with The farmland soil is mixed and used as a soil modifier, which is quite environmentally friendly.
較佳的是，含細料級以下尺寸的水洗式高爐渣是將粒徑尺寸為8毫米以下的高爐渣經水洗及沉降分離後獲得。 Preferably, the water-washed blast furnace slag having a size below the fine material grade is obtained by washing and sedimenting the blast furnace slag having a particle size of 8 mm or less.
較佳的是，粒徑尺寸為8毫米以下的高爐渣於水洗後成為水洗式高爐渣的泥水，水洗式高爐渣的泥水係先經磁選篩出含鐵的殘鋼，再行沉降分離而獲得含細料級以下尺寸的水洗式高爐渣。 Preferably, the blast furnace slag having a particle size of 8 mm or less is washed into water of the blast furnace slag, and the mud water of the blast furnace slag is first subjected to magnetic separation to sieve the residual steel containing iron, and then sedimentation and separation are obtained. A water-washed blast furnace slag containing a size below the fine grade.
較佳的是，含細料級以下尺寸的水洗式高爐渣係為粒徑尺寸1毫米以下之水洗式高爐渣。 Preferably, the water-washed blast furnace slag having a size below the fine material grade is a water-washed blast furnace slag having a particle size of 1 mm or less.
本創作將含細料級以下尺寸的水洗式高爐渣用於製作農田便道鋪面或農田溝渠鋪面，其成本低廉且環保；而因含細料級以下尺寸的水洗式高爐渣乾燥膠結固化後相當密實，因此其所製成之農田便道鋪面或農田溝渠鋪面不會生長雜草、因此無須另外噴灑除草劑，也能保護農田便道於雨天時不會被沖刷掉或是產生泥濘，使得與後車輛仍可正常通行，農田溝渠亦不會因田水流動而逐漸填平；當農田便道或農田溝渠不再使用或改道時，本創作之水洗式高爐渣製作的農田便道鋪面與農田溝渠鋪面，係能就地破碎與農田土壤混合，作為土壤改質劑使用，進而可節省額外廢棄物處理及土壤改質劑費用；另，本案控制含細料級以下尺寸的水洗式高爐渣之粒徑尺寸大小，使得所 製程之農田便道鋪面或農田溝渠鋪面的強度係介在車輛和農耕人員能走動與方便拆除的範圍內。 This creation will use water-washed blast furnace slag with the size below the fine material level to make farmland pavement or farmland ditch pavement, which is low in cost and environmentally friendly; and the water-washed blast furnace slag containing the fine material grade below is solidified and solidified after solidification. Therefore, the farmland pavement or farmland ditch pavement made by it will not grow weeds, so there is no need to spray another herbicide, and it can protect the farmland from being washed away or muddy on rainy days, so that the vehicle still has It can be used normally, and the farmland ditch will not be gradually filled due to the flow of the field water. When the farmland or farmland ditch is no longer used or diverted, the farmland pavement and farmland ditch pavement made by the created washed blast furnace slag can be In-situ crushing is mixed with farmland soil and used as a soil modifier to save additional waste treatment and soil modifier costs. In addition, this case controls the particle size of water-washed blast furnace slag containing fines below the fine grade.

以下係透過具體實施例對本創作進行說明。 The present invention is described below by way of specific examples.
將煉鋼廠中之高爐中取得的高爐渣以水洗篩分機篩選出粒徑尺寸8毫米以下之高爐渣，接著將粒徑尺寸8毫米以下之高爐渣送至洗砂機內水洗以去除其中的沙而得到水洗式高爐渣的泥水，水洗式高爐渣的泥水中的主要成分係為一氧化鈣、二氧化矽和三氧化二鋁。 The blast furnace slag obtained in the blast furnace of the steelmaking plant is screened with blast furnace slag having a particle size of 8 mm or less by a water washing sifter, and then the blast furnace slag having a particle size of 8 mm or less is sent to a sand washing machine for washing to remove the blast furnace slag. The mud water of the washed blast furnace slag is obtained by sand, and the main components of the water of the washed blast furnace slag are calcium oxide, cerium oxide and aluminum oxide.
再透過磁選機將水洗式高爐渣的泥水中含鐵的殘鋼篩出後可得經磁選的水洗式高爐渣的泥水。 Then, the residual iron containing iron in the muddy water of the blast furnace slag is sieved out through a magnetic separator to obtain the muddy water of the magnetically selected water-washed blast furnace slag.
接著將經磁選的水洗式高爐渣的泥水置於沉降池中進行沉降，其係於沉降池中設立一隔板，該隔板之高度係低於沉降池之周壁，並藉由強力幫浦的輔助，使得部分經磁選的水洗式高爐渣的泥水於隔板之前就沉澱下來，此部分於隔板之前就沉澱下來之泥水即係為細料級以上尺寸之水洗式高爐渣；而其餘部分未於隔板之前沉澱之 經磁選的水洗式高爐渣的泥水，其尺寸更小(平均粒徑為1毫米以下)，故繼續越過隔板而沉降在隔板之後，此部分未於隔板之前沉澱則係為含細料級以下尺寸的水洗式高爐渣。 Then, the muddy water of the magnetically selected water-washed blast furnace slag is placed in a sedimentation tank for settlement, which is set up in the sedimentation tank to establish a partition, the height of the partition is lower than the peripheral wall of the sedimentation tank, and is assisted by a powerful pump. Therefore, the muddy water of the partially magnetically washed blast furnace slag is precipitated before the separator, and the muddy water precipitated before the partition is a fine-grade water-washing blast furnace slag; and the rest is not Precipitated before the separator The magnetically selected water-washed blast furnace slag has a smaller size (average particle size of 1 mm or less), so it continues to pass over the separator and settles behind the separator. This portion is not fined before sedimentation. Water-washed blast furnace slag of the following size.
將含細料級以下尺寸的水洗式高爐渣挖出後放置於廠房內自然乾燥至一定程度並仍保有水份，即可得經自然乾燥但保有水份之含細料級以下尺寸的水洗式高爐渣。 The water-washed blast furnace slag containing the size below the fine material grade is excavated and placed in the factory to be naturally dried to a certain extent and still retains moisture, so that it can be naturally dried but retains moisture and has a water-washing size below the fine grade. Blast furnace slag.
接著將經自然乾燥但保有水份之含細料級以下尺寸的水洗式高爐渣運送至農田便道鋪面或農田溝渠鋪面興建預定地，如圖1所示，接著將經自然乾燥但保有水份之含細料級以下尺寸的水洗式高爐渣塗佈於農田便道6之表面或農田溝渠8之壁面和底面，再以機械(怪手、鏟車或小型壓路機等)或人工的方式抹平並施以外力使其緊實，最後藉由日曬使得經自然乾燥但保有水份之含細料級以下尺寸的水洗式高爐渣完全乾燥並且膠結固化，即可完成農田便道鋪面1或農田溝渠鋪面2之鋪設。 Then, the naturally-dried but water-retained water-washed blast furnace slag containing the fine-grained size is transported to the farmland pavement or farmland ditch pavement to construct a predetermined place, as shown in Figure 1, and then naturally dried but retains moisture. The water-washed blast furnace slag containing the size below the fine material grade is applied to the surface of the farmland road 6 or the wall surface and the bottom surface of the farmland ditch 8, and then smoothed and applied by mechanical means (blame hand, forklift or small road roller, etc.) or artificially. External force to make it compact, and finally, by the sun drying, the naturally-dried but water-containing water-washing blast furnace slag containing the fine-grained size is completely dried and cemented to complete the farmland pavement 1 or farmland ditch pavement 2 Laying.
又如圖2所示，亦可將經自然乾燥但保有水份之含細料級以下尺寸的水洗式高爐渣填補於裝設有水管9之農田溝渠8，並將其抹平使之與周圍地面齊高，待日曬使其完全乾燥並膠結固化後，即完成農田溝渠鋪面2之鋪設。 As shown in FIG. 2, the naturally-dried but moisture-retaining water-washed blast furnace slag having the size below the fine material level can also be filled in the farmland ditch 8 in which the water pipe 9 is installed, and smoothed and surrounded. The ground is high, and after the sun is completely dried and cemented and solidified, the laying of the farmland ditch pavement 2 is completed.
如附件一所示，現有技術的農田溝渠多半由泥土所建構而成，在未鋪設水洗式高爐渣前，現有技術的農田溝渠不僅有雜草叢生的問題，老鼠、蛇類更容易躲藏在 其中，而危害到農夫的生命安全、降低農田溝渠的使用性；反觀附件二，使用本創作含細料級以下尺寸的水洗式高爐渣所鋪設而成之農田溝渠鋪面則能完全杜絕雜草叢生的問題，從而免除農民需使用除草劑整理農田溝渠的不便利性。 As shown in Annex 1, most of the farmland ditches of the prior art are constructed of soil. Before the water-washed blast furnace slag is laid, the existing farmland ditch not only has the problem of weeds, but mice and snakes are more likely to hide. Among them, it harms the life safety of farmers and reduces the usability of farmland ditch; in contrast, in Annex 2, the farmland ditch pavement made by using the water-washed blast furnace slag containing the size below the fine material level can completely eliminate the weeds. The problem, thus eliminating the need for farmers to use herbicides to sort out the inconvenience of farmland ditch.
本創作之原料係為煉鋼廠高爐熔煉之後的廢棄物，其取得容易、價格便宜，將可有效降低興建農田便道鋪面以及農田溝渠鋪面之費用，且讓廢棄物再利用亦符合環保的概念；而鋪設農田便道鋪面或農田溝渠鋪面後可避免雜草之叢生、蛇鼠的窩藏、溝渠的填平，將可以擁有協助農民減少除草劑之費用、增進在農作時之安全以及免去重新開挖溝渠的費用等優點，且當農田便道鋪面或農田溝渠鋪面不需使用時，也可直接破碎後做為土壤改質劑使用。 The raw material of this creation is the waste after smelting in the blast furnace of the steelmaking plant. It is easy to obtain and cheap, and it will effectively reduce the cost of constructing farmland pavement and farmland ditch pavement, and recycling waste is also in line with the concept of environmental protection; After laying farmland pavement or farmland ditch paving, it can avoid the weeds, the nesting of snakes and rats, and the filling of ditches, which will help farmers reduce the cost of herbicides, improve the safety during farming and avoid re-excavation. The cost of the ditch and other advantages, and when the farmland pavement or farmland ditch pavement is not needed, it can also be directly crushed and used as a soil modifier.
另，由於含細料級以下尺寸的水洗式高爐渣挖出後係放置於廠房內自然乾燥，因此不需要額外加熱烘乾，將可以有效的減少能源的使用；且自然乾燥之一定程度仍保有水份，藉由保有的水份將可以避免運送途中經自然乾燥但保有水份之含細料級以下尺寸的水洗式高爐渣因被風吹得到處飄散而造成空氣汙染，將能降低運送時所需之保護設備的要求。 In addition, since the washed blast furnace slag containing the size below the fine material level is naturally dried after being excavated in the factory, no additional heating and drying is required, which can effectively reduce the use of energy; and the natural drying is still maintained to some extent.
