鐵路護(hù)欄網(wǎng)，也稱為鐵路隔離圍欄，是重要的交通基礎(chǔ)設(shè)施。制造鐵路護(hù)欄網(wǎng)的要求非常嚴(yán)格，特別是在安全性和實(shí)用性方面。護(hù)欄網(wǎng)由優(yōu)質(zhì)的低碳鋼絲或不銹鋼絲編織和焊接而成，它的網(wǎng)格結(jié)構(gòu)簡單，易于運(yùn)輸，并且安裝不受地形波動的限制，并且可以很好地適應(yīng)山脈，斜坡和彎曲區(qū)域。
Railway fence, also known as railway isolation fence, is an important transportation infrastructure. The requirements of manufacturing railway fence are very strict, especially in terms of safety and practicability. The guardrail net is made of high quality low carbon steel wire or stainless steel wire. Its grid structure is simple, easy to transport, and its installation is not limited by terrain fluctuation, and it can be well adapted to mountains, slopes and bending areas.
鐵路護(hù)欄網(wǎng)是相對常見的防護(hù)網(wǎng)，尤其是在高速鐵路上。大型高速鐵路通車時(shí)，兩側(cè)的鐵路護(hù)欄網(wǎng)起著巨大的作用。在隔離，保護(hù)和安全應(yīng)對各種緊急情況的過程中，鐵路護(hù)欄網(wǎng)發(fā)揮了巨大的幫助作用。
Railway fence is a relatively common protective net, especially on high-speed railway. When the large-scale high-speed railway is opened to traffic, the railway fence on both sides plays an important role. In the process of isolation, protection and safety response to various emergencies, railway fence has played a great role in helping.
鐵路護(hù)欄網(wǎng)的建設(shè)也是一個(gè)巨大的工程。在早期階段，有必要對施工路段進(jìn)行現(xiàn)場勘測，并對山區(qū)和坡度路段進(jìn)行勘察，以確保鐵路護(hù)欄網(wǎng)施工的安全。另外，在完成測繪工作之后，下一步是在現(xiàn)場安裝并鋪設(shè)，著重于鐵路護(hù)欄網(wǎng)支架的固定，因?yàn)檫@是承載兩個(gè)相鄰護(hù)欄網(wǎng)的重要環(huán)節(jié)。安裝鐵路護(hù)欄網(wǎng)時(shí)，請注意以下三點(diǎn)：
The construction of railway fence is also a huge project. In the early stage, it is necessary to carry out on-the-spot investigation to the construction section, and to investigate the mountainous area and the slope section, so as to ensure the safety of the railway fence construction. In addition, after the completion of the surveying and mapping work, the next step is to install and lay on the site, focusing on the fixing of the rail fence bracket, because it is an important link to carry two adjacent guardrail nets. When installing railway guardrail, please pay attention to the following three points:
1.鐵路護(hù)欄網(wǎng)柱圖;這是測繪的一步，要根據(jù)實(shí)際地形，必須通過鐵柵欄網(wǎng)的安裝，測量特定的坡度和地形，是否適合地下樁的安裝和固定。
1. Column diagram of railway guardrail net; this is a step of Surveying and mapping. According to the actual terrain, it is necessary to measure the specific slope and terrain through the installation of iron fence net to determine whether it is suitable for the installation and fixation of underground piles.
2.柱子深埋距離;一些地面不適合進(jìn)行柱子的深埋，則不能進(jìn)行柱子的安裝?；A(chǔ)部分需要用夯錘打，以使內(nèi)部結(jié)構(gòu)更堅(jiān)固耐用，或采用列調(diào)整方法。在施工過程中，對于深度不穩(wěn)，結(jié)構(gòu)不合理的地形，應(yīng)謹(jǐn)慎安裝立柱。
2. The deep buried distance of the column; if some ground is not suitable for the deep burial of the column, the installation of the column cannot be carried out. The foundation part needs to be hammered to make the internal structure more robust and durable, or adopt column adjustment method. In the process of construction, columns should be installed carefully for the terrain with unstable depth and unreasonable structure.
3.圍欄的連接;兩個(gè)相鄰網(wǎng)格之間的部分是鐵路護(hù)欄網(wǎng)的密集部分，這里的構(gòu)造應(yīng)該合理，注意使用優(yōu)質(zhì)堅(jiān)固的原材料作為優(yōu)質(zhì)圍欄產(chǎn)品，外觀質(zhì)量直接影響施工進(jìn)度。因此，使用穩(wěn)定，耐腐蝕的護(hù)欄網(wǎng)不僅有利于整個(gè)施工進(jìn)度，而且可以保證鐵路的安全性和平穩(wěn)性。
3. Connection of fence; the part between two adjacent grids is the dense part of railway guardrail net, the structure here should be reasonable, pay attention to the use of high-quality and solid raw materials as high-quality fence products, the appearance quality directly affects the construction progress. Therefore, the use of stable, corrosion-resistant guardrail net is not only conducive to the whole construction progress, but also can ensure the safety and stability of the railway.
