水泥防撞墻模具當(dāng)預(yù)埋件與護(hù)欄鋼筋出現(xiàn)沖突時(shí)，適當(dāng)移動(dòng)鋼筋位置，保證預(yù)埋件位置準(zhǔn)確，清掃預(yù)制構(gòu)件表面，并用水沖洗干凈，水泥防撞墻模具鑿毛上根據(jù)測(cè)量確定的防護(hù)欄邊線，采用人工對(duì)護(hù)欄邊線范圍內(nèi)的箱梁表面進(jìn)行鑿毛處理，鑿除混凝土表面的水泥砂漿和松弱層，并用水沖洗干凈，水泥防撞墻模具鋼筋的加工及安裝主線邊防撞護(hù)和匝道防撞護(hù)欄順橋向每2m設(shè)置一道假縫，嚴(yán)格按照設(shè)計(jì)圖紙對(duì)上述預(yù)埋件進(jìn)行埋設(shè)，預(yù)埋件安裝要做到不遺漏，定位準(zhǔn)確。設(shè)計(jì)伸縮縫處鋼筋要斷開(kāi)，斷面要整齊。清掃預(yù)制構(gòu)件表面，并用水沖洗干凈。模具生產(chǎn)過(guò)程中的細(xì)節(jié)會(huì)影響模具的使用和性能，對(duì)模具使用后保養(yǎng)方式要注重，保證模具的使用次數(shù)。

Before formwork erection, it is necessary to measure to correct the foundation elevation of anti-collision wall. Too high or too low foundation will have a very serious impact on the later ctruction. If it is too high, the higher part must be chiseled out when installing the formwork, which is time-cuming, laborious and expensive. If it is too low, there may be gaps at the bottom of the formwork in the later stage, which will cause cement slurry to flow out and cause pockmarked surface.

支模時(shí)需要測(cè)量來(lái)確定防撞墻的平面位置和鋼模的標(biāo)高，這決定了防撞墻的線型和美觀問(wèn)題，測(cè)量不準(zhǔn)確，容易造成防撞墻歪歪扭扭、高低不平，嚴(yán)重的甚至?xí)乱欢畏雷矇π纬慑e(cuò)臺(tái)，一旦產(chǎn)生錯(cuò)臺(tái)，后期的處理將會(huì)耗費(fèi)更多的時(shí)間、精力、金錢。測(cè)量準(zhǔn)確了，防撞墻成型以后，線型流暢，看起來(lái)就會(huì)很舒服、很漂亮。

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(jiàn)。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(kāi)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。
