C型钢拔桩及维护实用技巧

来源:http://www.jnjgcg.com/ 日期:2022-11-22 发布人:jiangucaigang
c型钢由C型钢成型机自动加工成型的。C型钢成型机根据给定的C型钢尺寸就可以自动完成C型钢的成型工艺。冷弯型钢用钢板或带钢在冷状态下弯曲成的各种断面形状的成品钢材。下面济南C型钢厂为您讲解相关内容。
C-shaped steel is automatically processed by C-shaped steel forming machine. The C-beam forming machine can automatically complete the forming process of C-beam according to the given C-beam size. Cold formed section steel refers to the finished steel products of various sectional shapes formed by bending steel plates or strips in cold state. Next, Jinan C Steel Plant will explain relevant contents to you.
冷弯型钢是一种经济的截面轻型薄壁钢材,C型钢围堰结构需要支承围堰内侧,根据围堰的大小和深度,需要选择钢管、工字梁或c型钢支承。小型围堰可以根据自己的经验建造,但当需要为围堰的总体结构设计大型围堰时,通常使用有限元分析软件型钢设计,以确保围堰的总体结构稳定。
The cold-formed steel is a kind of light thin-walled steel with economical section. The C-shaped steel cofferdam structure needs to support the inner side of the cofferdam. According to the size and depth of the cofferdam, steel pipes, I-beams or C-shaped steel need to be selected for support. Small cofferdams can be built according to their own experience, but when it is necessary to design large cofferdams for the overall structure of cofferdams, the finite element analysis software is usually used to design section steel to ensure the overall structural stability of the cofferdams.
C型钢的后期工作包括防漏检查和c型钢拔出。检漏相对简单,只要注意c型钢的动态特性,以及外界条件的变化对c型钢的影响。例如,水封c钢要注意水位的高低,波浪对c钢的影响要及时预防。
The later work of C-shaped steel includes leak proof inspection and c-shaped steel pullout. Leak detection is relatively simple, as long as we pay attention to the dynamic characteristics of c-beam and the influence of changes in external conditions on c-beam. For example, the water seal c steel should pay attention to the height of the water level, and the impact of waves on c steel should be timely prevented.

但是c型钢的拔出要注意一些技巧,根据沉桩时的情况确定拔出起点,拔出起点一般是离角桩5以上,拔出顺序与打桩相反,也可采用跳桩的方法。利用振动锤对桩型钢振动,减小土体的附着力,然后型钢振动和拉拔。
However, some skills shall be paid attention to the pulling out of c-shaped steel. The starting point of pulling out shall be determined according to the conditions during pile sinking. The starting point of pulling out is generally more than 5 away from the corner pile. The pulling out sequence is opposite to that of pile driving, and the method of pile jumping can also be used. The vibratory hammer is used to vibrate the pile profile steel to reduce the soil adhesion, and then the profile steel is vibrated and pulled.
对于难以清除的板桩,采用振动锤振动桩长100ー300mm,采用间歇振动法。振动锤每次振动15分钟,振动时间不超过1.5小时,可与振动锤交替振动和抽拉。及时拔桩后回填土洞。
For the sheet piles that are difficult to remove, the vibrating hammer shall be used to vibrate the pile with a length of 100 ー 300mm, and the intermittent vibration method shall be used. The vibration hammer shall be vibrated for 15 minutes each time, and the vibration time shall not exceed 1.5 hours. It can be alternately vibrated and pulled with the vibration hammer. The soil hole shall be backfilled after pile pulling.
在c型钢后期,尤其是拔桩工作中,做好拔桩工作也十分重要。如处理不当,会影响C型钢的再利用,所以您在使用前后不管什么操作要处理得当,更多相关内容就来我们网站http://www.jnjgcg.com进行咨询吧!
In the later stage of c-section steel, especially in the pile pulling work, it is also very important to do a good job in the pile pulling work. Improper handling will affect the reuse of C-beam, so no matter what operations you need to handle properly before and after use, more relevant content will come to our website http://www.jnjgcg.com Consult!
