打鱼注册送分 对混凝土工程利用

来历:http://zhaoyanfilter.com/ 时候:2021-02-26

(1)手推车、翻斗车野生运输。经常利用于混凝土运输量不大且运输距离近的环境,但运输速率最慢。
(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)自卸汽车运输。经常利用于混凝土运输量较大而运距较远的环境,车体为密封状况,便利保温保湿,首要在搅拌站利用。
(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)塔吊吊运。经常利用于大型水电工程的混凝土浇筑,凡是吊斗出口至混凝土仓面间的高度不跨越1.5~3.0m,但运输速率较慢。
(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)皮带运输机运输。凡是运输时应以程度输送较好,且运输速率不宜跨越1.2m/s,以防止因运速太快而形成混凝土分手景象。
(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)混凝土泵送运输。包含活塞式、风动式,经常利用于运输便利且混凝土量较大的环境,运输速率较快,但会受现场前提影响。
(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.

混凝土浇筑体例的遴选混凝土浇筑时应按照现场前提及详细工程环境拔取,凡是须要计较混凝土分层距离时候,其不应大于混凝土固结时候。经常利用的混凝土浇筑体例首要分为周全分层、分段分层和斜向分层3种体例,周全分层经常利用于大致积混凝土;分段分层合用于布局厚度不大而面积或长度较大的环境;斜向分层多用于大致积混凝土,长度较大的布局,斜面角度普通小于或即是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.
混凝土振捣机器的遴选混凝振捣时应斟酌选型机器的振捣规模,并按照现场环境停止遴选。凡是混凝土振捣器按其振动体例可分为内部式振动器和内部式振动器,前者又称为拔出式振动器,多用于振捣现浇根本、柱、梁、墙等布局构件和后打体积根本的混凝土,振捣时应防止碰撞钢筋、模板、芯管、吊环或预埋件。
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.
后者又称为平板式振动器、附着式振动器,常合适厚度不厚的板,用于构件外表振捣,振捣时内部式振动器的挪动间距应保障振动器底板能够笼盖到已振实局部的边缘。
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.
