强夯机施工进度的检查和影响因素

网址:http://www.sddhfjx.cn/   发布日期:2020-10-09 关注次数:
强夯机施工工期是正道,没有工期就说明利润遥不可及,在施工进度缓慢时,一定要找准难点,克服难点,知己知彼百战百胜!正是由于各种因素的影响,经常会打乱原始计划的安排并出现进度偏差,不变是相对的,变化是绝对的,所谓“计划赶不上变化”,从而使强夯施工阶段的进度控制显得非常重要。因此,应及时了解和掌握工程实际进展情况,分析和检查影响进度偏差的原因,并为工程施工进度的调整和控制提供信息、依据。
The construction period of dynamic compaction machine is the right way. If there is no construction period, it means that the profit is far away. When the construction progress is slow, we must find out the difficulties, overcome the difficulties, know ourselves and know the enemy, and win a hundred battles! Due to the influence of various factors, the original plan is often disturbed and the schedule deviation occurs. The invariance is relative, and the change is absolute. The so-called "plan can not catch up with the change", so the schedule control of dynamic compaction construction stage is very important. Therefore, we should timely understand and master the actual progress of the project, analyze and check the reasons affecting the progress deviation, and provide information and basis for the adjustment and control of the construction progress.

1、强夯施工进度的检查方式:在工程进度计划实施后,应及时跟进并收集工程实际进展情况,包括工作的开始时间、完成时间、持续时间、逻辑关系、实物工程量和工作量,以及工作时差的利用情况等,从中了解到施工过程中影响进度的潜在问题,以便及时采取相应的措施加以预防和防止偏差、纠正偏差。
1. Inspection method of dynamic compaction construction progress: after the implementation of the project schedule, the actual progress of the project should be timely followed up and collected, including the start time, completion time, duration, logical relationship, physical quantities and workload, as well as the utilization of working time difference, so as to understand the potential problems affecting the progress in the construction process, so as to take timely measures Measures should be taken to prevent, prevent and correct deviations.
2、强夯施工进度的检查方法:施工进度的检查方法主要是对比法,有利用横道图比较法、S型曲线比较法、香蕉型曲线比较法、前锋线比较法、列表比较法等将经过整理的实际进度的数据与计划进度的数据相比较,从而发现是否出现偏差和偏差的大小。若偏差较小,可在分析其产生原因的基础上采取有效的措施,使矛盾得以解决,继续执行原计划;若偏差较大,经过努力不能按原计划实现时,则要考虑对计划进行必要的调整,即适当延长工期或改变施工速度。
2. Inspection method of dynamic compaction construction progress: the inspection method of construction progress is mainly comparison method, including bar chart comparison method, S-curve comparison method, banana curve comparison method, Qianfeng line comparison method, list comparison method, etc., to compare the sorted actual progress data with the planned progress data, so as to find out whether there is deviation and the size of deviation. If the deviation is small, effective measures can be taken on the basis of analyzing the causes to solve the contradiction and continue to implement the original plan; if the deviation is large and cannot be realized according to the original plan after efforts, it is necessary to adjust the plan, that is, appropriately extend the construction period or change the construction speed.

影响强夯施工进度的因素:由于工程建设项目具有庞大、复杂、周期长、相关单位多等特点,故影响强夯工程施工进度有很多其它的因素,主要有来源于工程建设相关单位影响。
Factors affecting the construction progress of dynamic compaction: due to the characteristics of large, complex, long cycle and many related units, there are many other factors affecting the construction progress of dynamic compaction project, mainly from the influence of relevant units of engineering construction.
产生的原因: ①在估计了工程的特点及工程实现的条件时,过高地估计了有利因素和过低地估计了有利因素。
The reasons are as follows: 1) when we estimate the characteristics of the project and the conditions for its realization, we overestimate the favorable factors and underestimate the favorable factors.
②在工程实施过程中各有关方面工作上的失误。
② In the process of project implementation, the work of all relevant aspects of the error.
③不可预见事件的发生。
③ The occurrence of unforeseen events.
【强夯理论】强夯法即强力夯实法,又称动力固结法。是利用大型履带式强夯机将8-30吨的重锤从6-30米高度自由落下,对土进行强力夯实,迅速提高地基的承载力及压缩模量,形成比较均匀的、密实的地基,在地基一定深度内改变了地基土的孔隙分布。 强夯法施工已广泛运用到高速公路铁路,机场、核电站、大工业区、港口填海等基础加固工程。优点工期短、效果好、造价低。
[dynamic compaction theory] dynamic compaction method is strong compaction method, also known as dynamic consolidation method. It is to use the large crawler type dynamic rammer to free fall 8-30 tons of heavy hammer from 6-30 meters high to tamp the soil, rapidly improve the bearing capacity and compression modulus of the foundation, form a relatively uniform and dense foundation, and change the pore distribution of the foundation soil within a certain depth of the foundation. Dynamic compaction method has been widely used in highway, railway, airport, nuclear power plant, large industrial area, port reclamation and other foundation reinforcement projects. It has the advantages of short construction period, good effect and low cost.

1、经过多年的实践及强夯设备的更新,强夯法施工已广泛运用到高速公路铁路,机场、核电站、大工业区、港口填海等基础加固工程,并对相对较复杂的地质如高填方基础,高含水量基础,港口填海基础,海水吹填基础等都有成功的施工案例。
1. After years of practice and updating of dynamic compaction equipment, dynamic compaction construction has been widely used in highway, railway, airport, nuclear power plant, large industrial area, port reclamation and other foundation reinforcement projects. There are successful construction cases for relatively complex geology, such as high fill foundation, high water content foundation, port reclamation foundation, sea water reclamation foundation, etc.
2、 强夯法适用于处理碎石土、砂土、低饱和度的粉土与粘性土、湿陷性黄土、素填土和杂填土等基。
2. The dynamic compaction method is suitable for the treatment of gravel soil, sandy soil, silt and cohesive soil with low saturation, collapsible loess, plain fill and miscellaneous fill.
3、 强夯施工前应在施工现场有代表性的场地上选取一个或几个试验区,进行试夯或试验性施工。试验区数量应根据建筑场地复杂程度、建设规模及建筑类型确定。
3. Before dynamic compaction construction, one or several test areas should be selected on the representative site of the construction site for trial compaction or experimental construction. The number of test areas should be determined according to the complexity of construction site, construction scale and building type.
