水泥撒布車是路面基層施工中不可或缺的關(guān)鍵設(shè)備，其通過(guò)機(jī)械傳動(dòng)準(zhǔn)確控制撒布量，能均勻鋪設(shè)水泥等膠凝材料，大幅提升施工效率并減少材料浪費(fèi)。作為冷再生工藝的“黃金搭檔”，水泥撒布車的性能直接關(guān)系到再生路面的強(qiáng)度與耐久性。隨著公路建設(shè)與養(yǎng)護(hù)工程對(duì)材料鋪設(shè)精度要求的不斷提高，越來(lái)越多的施工單位選擇通過(guò)租賃方式獲取這一專業(yè)化設(shè)備。

The cement spreader is an indispensable key equipment in road base construction. It precisely controls the spreading amount through mechanical transmission, and can evenly lay cement and other cementitious materials, greatly improving construction efficiency and reducing material waste. As the "golden partner" of cold recycling technology, the performance of cement spreader is directly related to the strength and durability of recycled pavement. With the continuous improvement of material laying accuracy requirements in highway construction and maintenance projects, more and more construction units choose to obtain this specialized equipment through leasing.

水泥撒布車主要分為粉料撒布車和水泥凈漿灑布車兩大類，適用于不同的施工場(chǎng)景。

Cement spreading vehicles are mainly divided into two categories: powder spreading vehicles and cement slurry spreading vehicles, which are suitable for different construction scenarios.

粉料撒布車適用于公路現(xiàn)場(chǎng)冷再生工程或路基穩(wěn)定土施工，需要撒布的是干燥的水泥粉、石灰粉或粉煤灰。其工作原理是：粉體倉(cāng)儲(chǔ)存待撒布的粉料，位于倉(cāng)底部的給料螺旋輸送機(jī)將粉料持續(xù)供應(yīng)地輸送到撒布裝置，按照設(shè)定的寬度與厚度均勻撒布在施工路面上。粉料撒布車通常配備巨大的粉料倉(cāng)和螺旋輸送系統(tǒng)，并配有除塵裝置，避免施工揚(yáng)塵。撒鋪寬度范圍通常在0.8至2.5米之間，以0.8米為單位任意調(diào)節(jié)；每平方米撒布量可在1至40公斤之間任意調(diào)節(jié)。

The powder spreading vehicle is suitable for cold recycling projects or stable soil construction on highways, and it needs to spread dry cement powder, lime powder, or fly ash. Its working principle is: the powder storage stores the powder to be spread, and the feeding screw conveyor located at the bottom of the warehouse continuously transports the powder to the spreading device, which evenly spreads it on the construction road surface according to the set width and thickness. Powder spreading vehicles are usually equipped with large powder silos and spiral conveying systems, as well as dust removal devices to avoid construction dust. The spreading width range is usually between 0.8 and 2.5 meters, and can be adjusted arbitrarily in units of 0.8 meters; The spreading amount per square meter can be adjusted between 1 and 40 kilograms.

水泥凈漿灑布車則適用于穩(wěn)定層分層施工時(shí)上下層之間的水泥凈漿灑布。其主要應(yīng)用于高等級(jí)公路施工，在底基層水穩(wěn)和上層水穩(wěn)之間灑布一層水泥漿，利用水泥漿的粘結(jié)力增加水穩(wěn)的整體性，從而提高公路基層的穩(wěn)定性和整體強(qiáng)度。傳統(tǒng)施工中，水泥凈漿灑布主要靠人力完成，存在人力投入大、灑布效果差、安全隱患多等缺陷。

The cement slurry spraying truck is suitable for spraying cement slurry between the upper and lower layers during the layered construction of the stable layer. It is mainly used in the construction of high-grade highways, where a layer of cement slurry is sprayed between the water stability of the base layer and the upper layer, and the bonding force of the cement slurry is used to increase the overall stability of the water stability, thereby improving the stability and overall strength of the highway base layer. In traditional construction, cement slurry spraying is mainly completed by manpower, which has defects such as high manpower investment, poor spraying effect, and multiple safety hazards.
