防撞墻模具重要性是以公路所需要的混凝土防撞墻為例，因?yàn)榉雷矇δ＞呤枪穼俣ㄖ频哪０澹饕菫榱吮Ｕ习踩鲂卸ㄖ频?，所以在防撞墻鋼模板的制作上各式各樣，但總體是由兩片模板構(gòu)成的。

防撞墻模具介紹和常用尺寸是在根據(jù)不同地區(qū)使用的中央防撞墻以及路邊防撞墻兩種不同了類型模板的劃分。通過(guò)對(duì)現(xiàn)澆防撞墻的制作可以發(fā)現(xiàn)，即便在不同地區(qū)、不同公路等級(jí)上使用的模具，其具體制作方案和模板材質(zhì)都是相同的，只不過(guò)在模具焊接之前需要對(duì)不同尺寸的進(jìn)行不同的下料、切割等。那么以防撞墻模具為主的鋼模具，整個(gè)生產(chǎn)流程是怎樣的呢？

1.箱梁鋼筋安裝時(shí)，根據(jù)防撞墻位置準(zhǔn)確放線，拉雙線（底部和頂部）預(yù)埋防撞墻鋼筋；箱梁施工完成后檢查、調(diào)整預(yù)埋鋼筋位置，拉線綁扎剩余鋼筋，保護(hù)層墊塊應(yīng)綁扎牢固，扎絲頭不得侵入保護(hù)層；穿入預(yù)埋管道（伸縮縫、斷縫處斷開鋼筋，按設(shè)計(jì)要求設(shè)置鋼套管）。

1. When the reinforcement of box girder is installed, according to the ition of the anti-collision wall, the double-line (bottom and top) is drawn to precisely embedding the anti-collision wall reinforcement; after the ctruction of box girder, the ition of the embedded reinforcement bar is checked and adjusted, the remaining reinforcement bar is tied by the wire, the cushion block of the protective layer should be firmly tied, and the wire-binding head should not penetrate the protective layer; and the embedded pipeline (expansion and contractio) should be penetrated. The steel bars are broken at the joints and the broken joints, and the steel sleeves are set up according to the design requirements.

防撞墻是為了防止車輛沖到道路以外的或者橋梁以外而設(shè)置的，一般在高速公路橋梁中多見。為了減少車輛對(duì)周邊周邊區(qū)域造成的危險(xiǎn)性，防止車輛沖出橋梁也設(shè)置混凝土防撞墻。

Anti-collision walls are set up to prevent vehicles from rushing out of roads or bridges. They are usually found in highway bridges. In order to reduce the danger caused by vehicles to the surrounding areas, concrete anti-collision walls are also set up to prevent vehicles from rushing out of bridges.

近年來(lái)，隨著國(guó)家經(jīng)濟(jì)高速發(fā)展，全國(guó)基礎(chǔ)設(shè)施是建設(shè)漸入高潮，各地基礎(chǔ)設(shè)施建設(shè)如火如荼地開展起來(lái)，作為改善城市交通的重要手段之一，立交橋也在全國(guó)如雨后春筍般一座座矗立起來(lái)。防撞墻作為立交橋面系的重要組成部分，它不僅擔(dān)負(fù)著安全責(zé)任，還直接影響著橋梁的美觀，所以，如何對(duì)防撞墻施工質(zhì)量進(jìn)行良好的控制也成了一個(gè)不可忽視的問(wèn)題。
