对于强夯施工之前要充分考虑可能存在的内外界因素

对于强夯施工工程来说,强夯机夯锤的力量,会使土壤本身的结构受到一定的损坏,而空气中的气和液体,然后形成一个土体的结构,当强夯结束时是需要土壤颗粒变小,所以强度和模量是前进的。
For dynamic compaction construction project, the force of dynamic compaction machine rammer will damage the structure of the soil itself to a certain extent. The air and liquid in the air will form a soil structure. When the dynamic compaction is completed, the soil particles need to be smaller, so the strength and modulus are moving forward.
在这个过程中土壤含有的水和气都会被影响到,强夯机要是落锤不平稳的话,会容易出现坑壁崩塌;分层厚度过大的情况,或夯击能量不行,未到达有用影响深度。对附近建筑物发作空气影响。因强夯引起较强的振荡,施工前未充分考虑对周围建筑物的空气影响。
In this process, the water and air contained in the soil will be affected. If the hammer drop is not stable, the pit wall will collapse easily; If the layer thickness is too large, or the tamping energy is not enough, the useful influence depth is not reached. Air impact on nearby buildings. Due to strong vibration caused by dynamic compaction, the air impact on surrounding buildings was not fully considered before construction.
所以强夯的作用和力量不是越强越好,而是需要考虑遭到气、水量等影响,空隙水压流失小于土壤粒的侧向压力的,缝隙就会自行关闭,当土水在运动时会恢复到常态的。
Therefore, the effect and strength of dynamic compaction is not the stronger the better, but it needs to consider the influence of air and water. If the water pressure loss in the gap is less than the lateral pressure of soil particles, the gap will close itself, and the soil water will return to normal when it moves.
在另一方面,强夯周围会构成一些不规则的纵向裂缝,当出现涌水的时候。当孔隙水压力的流失时,土的承受强度和变形会被大幅度的增加,这是因为土粒之间是紧密接触的,吸附水层会被逐渐固定住,这是土的触变性所形成。
On the other hand, there will be some irregular longitudinal cracks around the dynamic compaction when there is water gushing. When the pore water pressure is lost, the bearing strength and deformation of the soil will be greatly increased, because the soil particles are in close contact with each other, and the adsorbed water layer will be gradually fixed, which is formed by the thixotropy of the soil.
然后,还要注意在强夯机施工完毕之后,强夯机也是需要定时保养的,在作业完毕后将驾驶室中的污垢和泥土擦拭干净,如果有外漏现象需要涂上黄油避免设备生锈,接着查看液压体系是否是漏油的,设备的衔接、外表是不是正常的,行走减速中要查看油量。
Then, it should be noted that after the construction of the dynamic compaction machine, the dynamic compaction machine also needs regular maintenance. After the operation, the dirt and soil in the cab should be wiped clean. If there is leakage, grease should be applied to avoid equipment rusting. Then check whether the hydraulic system is leaking, whether the connection and appearance of the equipment are normal, and check the oil quantity during the deceleration.
强夯机定时替换遍地减速机的齿轮油,每作业500个小时可进行一次。行走减速机油量查看和换油,每隔1500小时进行一次。变幅减速机油量查看和换油每隔1500小时进行一次。
The dynamic compaction machine can replace the gear oil of the reducer all over the place regularly, once every 500 hours of operation. Check and change the oil quantity of walking reducer every 1500 hours. Check and change the oil quantity of luffing reducer every 1500 hours.
以上就是强夯施工时所需要注意的一些关键信息,希望以上的内容会对您有一定的帮助,更多相关的信息小编也会陆续的整理发布到网站上,感谢您的观看。
The above is some key information that needs to be paid attention to during dynamic compaction construction. I hope the above content will be helpful to you. More relevant information will be published on the website one after another. Thank you for watching.
