1．施工機械

1. Construction machinery

必須配備齊全的施工機械和配件，做好開工前的保養(yǎng)、試機工作，并保證在施工期間一般不發(fā)生有礙施工進度和質量的故障。路面基層施工，采用集中廠拌、攤鋪機攤鋪、分層施工，要求各施工單位配備足夠的拌和、運輸、攤鋪、壓實機械。每層大壓實厚度不大于20cm。水泥穩(wěn)定碎石基層施工，按單幅分兩層梯隊攤鋪作業(yè)，因而必須配備以下主要機械。

It is necessary to equip complete construction machinery and accessories, carry out maintenance and testing work before starting work, and ensure that there are generally no faults that affect the construction progress and quality during the construction period. The construction of the pavement base layer adopts centralized plant mixing, paver paving, and layered construction. Each construction unit is required to be equipped with sufficient mixing, transportation, paving, and compaction machinery. The compacted thickness of each layer shall not exceed 20cm. The construction of cement stabilized crushed stone base requires the following main machinery to be equipped, as the paving operation is divided into two layers according to a single width.

（1）拌和機應配置產(chǎn)量大于400T/H的拌和機，要保證其實際出料（生產(chǎn)量的80%）能力超過實際攤鋪能力的10-15%。拌和機必須采用定型產(chǎn)品，并在多個工程中應用，且用戶反應良好。為使混合料拌和均勻，拌缸要滿足一定長度。至少要有五個進料斗，料斗上口必須安裝鋼筋網(wǎng)蓋，篩除超出粒徑規(guī)格的集料及雜物。拌和機的用水應配有大容量的儲水箱。

(1) The mixer should be equipped with a production capacity greater than 400T/H, ensuring that its actual discharge capacity (80% of the production capacity) exceeds 10-15% of the actual paving capacity. The mixer must use standardized products and be applied in multiple projects, with good user feedback. To ensure even mixing of the mixture, the mixing tank must meet a certain length. There must be at least five feeding hoppers, and steel mesh covers must be installed at the top of the hoppers to screen out aggregates and debris exceeding the particle size specifications. The water used in the mixer should be equipped with a large capacity water storage tank.

料斗、水箱、罐倉都要求裝配高精度電子動態(tài)計量器，電子動態(tài)計量器應經(jīng)有資質的計量部門進行計量標定后方可使用。

The hopper, water tank, and tank compartment all require the assembly of high-precision electronic dynamic meters. Electronic dynamic meters should be calibrated by qualified metrology departments before use.

（2）攤鋪機應根據(jù)路面基層的寬度、厚度，選用合適的攤鋪機械。基層施工應采用兩臺攤鋪機梯隊作業(yè)。要求兩臺攤鋪機功能一致，好為同一機型，而且機型較新，功能較全，以保證路面基層厚度一致，完整無縫，平整度好。

(2) The paver should select appropriate paving machinery based on the width and thickness of the road base layer. Grassroots construction should use two pavers in a cascade operation. Two pavers are required to have the same function, preferably the same model, and the model should be newer with more comprehensive functions, to ensure consistent thickness, complete and seamless pavement base layer, and good smoothness.

（3）壓路機至少應配備12T左右輕型壓路機1~2臺，18-20T的壓路機2~3臺，振動壓路機2~3臺和膠輪壓路機2臺。壓路機的噸位和臺數(shù)必須與拌和機及攤鋪機生產(chǎn)能力相匹配，使從加水拌和到碾壓終了的時間不超過水泥初凝時間，保證施工正常進行。

(3) At least 1-2 lightweight rollers with a capacity of around 12T, 2-3 rollers with a capacity of 18-20T, 2-3 vibrating rollers, and 2 rubber wheeled rollers should be equipped with the road roller. The tonnage and number of rollers must match the production capacity of the mixer and paver, so that the time from water mixing to the end of compaction does not exceed the initial setting time of cement, ensuring the normal construction.

（4）自卸汽車數(shù)量應與拌和設備、攤鋪設備、壓路機相匹配。

(4) The number of dump trucks should match the mixing equipment, paving equipment, and road rollers.

（5）裝載機

(5) Loader

（6）灑水車

(6) Sprinkler truck

（7）水泥鋼制罐倉由拌和機生產(chǎn)能力決定其容量，罐倉內應配有水泥破拱器，以免水泥起拱停流。

(7) The capacity of the cement steel tank silo is determined by the production capacity of the mixer, and a cement arch breaker should be equipped inside the silo to prevent cement from arching and stopping flow.

以上機械數(shù)量至少應滿足每個工點、每日連續(xù)正常生產(chǎn)及工期要求。

The above number of machinery should at least meet the requirements of each construction site, daily continuous normal production, and project schedule.

（1）底基層外形檢查

(1) Subbase appearance inspection

底基層外形檢查內容有高程、中線偏位、寬度、橫坡度和平整度。

The inspection of the appearance of the base layer includes elevation, centerline deviation, width, cross slope, and flatness.

（2）底基層壓實度檢查、修補與驗收

(2) Inspection, repair, and acceptance of subgrade compaction degree

底基層應進行壓實度和表面松散檢查，凡不符合要求的路段，應分別采用補充碾壓、填換好的材料等。

The compaction degree and surface looseness of the base layer should be checked. For sections that do not meet the requirements, supplementary rolling and replacement materials should be used separately.

（3）底基層沉降檢查

(3) Subbase settlement inspection

底基層的表面沉降速率應達到連續(xù)兩個月小于5mm/月才可鋪筑基層。
