1、解读人工挖孔桩技术在工程中的运用中英文 现代社会城市化进程的不断加快，各类民用与工业修建项目也日益添加。在每项修建工程中，都需求对修建质量和布局安全进行严厉控制，尤其是关于修建根底的处置需求更高。人工挖孔桩施工技能比拟便利，施工速度较快，且不需求运用大型的机械设备，对其它修建物的扰动影响也较小。一起，人工挖孔桩还能节约很多的施工本钱，其抗震才能要比木桩、混凝土打入桩强，因而在工民建工程中得到了十分广泛的运用。Accelerating the urbanization process in modern society, all kinds of civil and industrial con
2、struction projects are also increasing. In every building project, and need to strictly control the construction quality and structural safety, especially for building foundation processing requirements are higher. Artificial dig-hole pile construction technology is more convenient, faster, and do n
3、ot need to apply a large machinery and equipment, less influence on other disturbances of the building. At the same time, the artificial dig-hole pile can also save a lot of construction cost, the aseismic capability than piles driven pile, concrete strength, thus got the very extensive application
4、in civil engineering.一、人工挖孔桩的技能关键Second, the main technical points of the artificial dig-hole pile（一）施工前的预备(a) the preparation for construction根据勘察成果编写切实可行的施工计划以及质量控制措施。别的，还大概将工地周围的安全隐患进行扫除，并对施工设备及机具等进行全部查看，以确保施工可以有序顺利进行；根据描绘与施工计划来断定好成孔的方位，向下挖1.5m左右的坑；对首节护壁进行浇筑，井圈的高度可恰当比地上高出0.5m，对对角拉线进行查看。According
5、to the survey results to write feasible construction scheme and quality control measures. In addition, should also eliminate safety concerns around the site, and the construction of facilities and equipment to conduct a comprehensive inspection, to ensure the orderly construction can proceed smoothl
6、y; According to the design and construction scheme to determine the good into the position of the hole, dig down the pit of 1.5 m or so; Casting of breast wall first, well circles height is 0.5 m higher than the ground, appropriate inspection on diagonal arrows.（二）人工挖孔(2) the artificial dig hole根据桩孔
7、散布状况及现场的地质状况来断定挖孔的次序。若是桩孔之间相距小于3.0m，则大概选用间隔开挖的挖孔办法，挖孔时孔与孔之间的间隔大概大于5m，挑选相对较远的当地来倾倒工程土方，技能人员在施工的进程中，大概时辰留心现场的地质状况能否存在改变，然后进行随时的地质勘察。若是发现异常，大概立刻中止施工，一起还大概向关联单位进行陈述，以确保施工的质量。施工人员在挖孔时，每挖进1.5m左右时，便需求对桩的直径及笔直度进行查看。人工挖孔桩的歪斜度大概坚持在0.6%之内。挖孔时若是遇到岩层，需求进行爆炸，可根据描绘计划，严厉控制炸药的用量，并对爆炸地址进行必要的支护；当挖进到描绘深度时，需求进行开桩孔的打扫作业，
8、以确保孔底的平坦和清洗。According to the distribution of pile hole holes and site geological conditions to determine the order. If spaced pile holes is less than 3.0 m, should adopt the interval excavation digging hole, dig a hole when the distance between the hole and the hole should be greater than 5 m, choos
9、e relatively far to dumping of earthwork engineering, technical personnel in the process of construction, should always pay attention to the scene of the geological situation whether there is any change, then carries on the geological survey at any time. If discovery is unusual, should immediately s
10、top the construction, should also report to the relevant units at the same time, in order to guarantee the quality of construction. Construction personnel in digging the hole, every dig into 1.5 m or so, it need to check the diameter of the pile and vertical degree. The inclination of the artificial
11、 dig-hole pile should be kept within 0.6%. Digging the hole if there are any rock, blasting is required, can according to the design plan, strictly control the amount of explosive, and the blasting site necessary support; When digging into the design depth, need to open a pile hole cleaning work, to
12、 ensure the smooth of the bottom of the hole and clean.（三）孔内钢筋笼装置Hole reinforcing cage (3) installation在人工挖孔桩成孔并经过检测合格今后，即可进行孔内钢筋笼装置工序。在钢筋笼装置第一步，需求将小台阶与独自箍筋一起放置，然后再把每一根纵向钢筋进行捆扎，焊接。将护壁加在小台阶处，然后运用三角形的钢筋在周围进行固定，以确保其不会变形、移位。每节护壁可在当日施工结束后24小时后撤除，若是发现护壁存在蜂窝或渗漏水疑问，大概及时进行补强，防止构成事端。In the artificial dig-hole
13、 pile hole and after testing qualified, reinforcing cage inside installation process can be achieved. In installation of reinforcing cage as a first step, need to place the small steps with stirrups together alone, then each longitudinal reinforcement for strapping, welding. Will be added in small s
14、teps, and protecting and using triangular reinforced around fixed, in order to make sure it will not deformation, displacement. Each section can be in after the completion of the construction and protecting removed after 24 hours, if found pottery honeycomb or seepage problems, should be timely to r
15、einforcing, avoid to cause accidents.（四）第二期间开挖(4) the second stage excavation进行第二期间开挖时，大概先从井口垂球吊线找出中间点，然后地井孔的底部打设一短木桩，将桩的中间投影到木桩的顶端，以此作为第二节护壁的土方开挖根据。在此期间施工进程中，大概严厉注重地质的改变状况。During the second stage excavation, find the center point should first from the wellhead suspension wire ball, and then set to
16、the bottom of the hole to play a short pile, the pile at the center of the projection to the top of the pile, as the earth excavation retaining wall in the second quarter. At this stage construction process, should be strictly pay attention to geological changes.（五）混凝土的浇筑(5) the pouring of concrete混凝土大概进行会集拌和，确保其坝落度在4cm8cm,混凝土下料可选用串桶，一起确保混凝土自在落下高度不大于2m，大概一边灌溉一边捣实，桩顶下3m处选用刺进式振捣器进行振捣。同一桩的混凝土浇筑大概一次性完结，且不留施工缝，若是因为特别缘由有必要留设备工缝时，有必要在混凝土周围插下短钢筋，然后加
