(1) Manual transportation by trolley and dumper. It is often used in the case of small amount of concrete transportation and short transportation distance, but the transportation speed is the slowest.
（2）自卸汽車運輸。常用于混凝土運輸量較大而運距較遠(yuǎn)的情況，車體為密封狀態(tài)，方便保溫保濕，主要在攪拌站應(yīng)用。
(2) Dump truck transportation. It is usually used in the case of large volume and long distance of concrete transportation. The car body is in a sealed state, which is convenient for heat preservation and moisture preservation. It is mainly used in the mixing station.
（3）塔吊吊運。常用于大型水電工程的混凝土澆筑，通常吊斗出口至混凝土倉面間的高度不超過1.5~3.0m，但運輸速度較慢。
(3) Tower crane lifting. It is often used in the concrete pouring of large hydropower projects. Generally, the height between the bucket outlet and the concrete warehouse surface is not more than 1.5 ~ 3.0m, but the transportation speed is slow.
（4）皮帶運輸機運輸。通常運輸時應(yīng)以水平運送較好，且運輸速度不宜超過1.2m/s，以免因運速太快而造成混凝土分離現(xiàn)象。
(4) Belt conveyor transport. Generally, it is better to transport the concrete horizontally, and the transportation speed should not exceed 1.2m/s, so as to avoid the separation of concrete due to too fast transportation speed.
（5）混凝土泵送運輸。包括活塞式、風(fēng)動式，常用于運輸不便且混凝土量較大的情況，運輸速度較快，但會受現(xiàn)場條件影響。
(5) Concrete pumping transportation. It includes piston type and pneumatic type. It is often used in the case of inconvenient transportation and large amount of concrete. The transportation speed is fast, but it will be affected by the site conditions.
混凝土澆筑方法的選擇混凝土澆筑時應(yīng)根據(jù)現(xiàn)場條件及具體工程情況選取，通常需要計算混凝土分層間隔時間，其不應(yīng)大于混凝土凝結(jié)時間。常用的混凝土澆筑方法主要分為全面分層、分段分層和斜向分層3種方式，全面分層常用于大體積混凝土；分段分層適用于結(jié)構(gòu)厚度不大而面積或長度較大的情況；斜向分層多用于大體積混凝土，長度較大的結(jié)構(gòu)，斜面角度一般小于或等于45°。
The selection of concrete pouring method should be based on the site conditions and specific engineering conditions. Generally, the interval time of concrete layering should be calculated, which should not be greater than the setting time of concrete. The commonly used concrete pouring methods are divided into three ways: overall layering, segmented layering and oblique layering. Overall layering is commonly used for mass concrete; segmented layering is suitable for the case of small structure thickness and large area or length; oblique layering is mostly used for mass concrete structure with large length, and the inclined plane angle is generally less than or equal to 45 degrees.
混凝土振搗機械的選擇混凝振搗時應(yīng)考慮選型機械的振搗范圍，并根據(jù)現(xiàn)場情況進行選擇。通?；炷琳駬v器按其振動方式可分為內(nèi)部式振動器和外部式振動器，前者又稱為插入式振動器，多用于振搗現(xiàn)澆基礎(chǔ)、柱、梁、墻等結(jié)構(gòu)構(gòu)件和后打體積基礎(chǔ)的混凝土，振搗時應(yīng)避免碰撞鋼筋、模板、芯管、吊環(huán)或預(yù)埋件。
The selection of concrete vibration machinery should consider the vibration range of the selected machinery, and select according to the site conditions. Generally, concrete vibrator can be divided into internal vibrator and external vibrator according to its vibration mode. The former is also called insert vibrator. It is mainly used to vibrate cast-in-place foundation, column, beam, wall and other structural components and concrete with volume foundation. When vibrating, it should avoid colliding with reinforcement, formwork, core pipe, rings or embedded parts.
后者又稱為平板式振動器、附著式振動器，常適合厚度不厚的板，用于構(gòu)件表面振搗，振搗時外部式振動器的移動間距應(yīng)保證振動器底板可以覆蓋到已振實部分的邊緣。
The latter is also called plate vibrator and attached vibrator. It is often suitable for the plate with less thickness and used for the surface vibration of components. The moving distance of external vibrator should ensure that the bottom plate of vibrator can cover the edge of the vibrated part.
