钢板桩怎样进行检验验收?
 
How to inspect and accept steel sheet piles?
 
对钢板桩,一般有材质检验和外观检验,以便对不合要求的钢板桩进行矫正,以减少打桩过程中的困难。
 
For steel sheet piles, there are generally material inspection and appearance inspection, so as to correct the unqualified steel sheet piles and reduce the difficulties in the process of piling.
 
(1)外观检验:包括表面缺陷、长度、宽度、厚度、端部矩形比、平直度和锁口形状等项内容。需注意:
 
(1) Appearance inspection: including surface defects, length, width, thickness, end rectangle ratio, straightness, lock mouth shape, etc. Note:
 
a、对打入钢板桩有影响的焊接件应予以割除;
 
a. The welding parts that affect the driving of steel sheet piles shall be cut off;
 
b、割孔、断面缺损的应予以补强处理;
 
b. Cut holes and section defects shall be reinforced;
 
c、若钢板桩有严重锈蚀,应测量其实际断面厚度。原则上要对全部钢板桩进行外观质量检查。
 
c. If the steel sheet pile is seriously rusted, the actual section thickness shall be measured. In principle, the appearance quality of all steel sheet piles shall be inspected.
(2)材质检验:对钢板桩母材的化学成分及机械性能进行全面试验。包括钢材的化学成分分析,构件的拉伸、弯曲试验,锁口强度试验和延伸率试验等项内容。每一种规格的钢板桩至少进行一个拉伸、弯曲试验:每20-50t重的钢板桩应进行两个试件试验。
 
(2) Material inspection: conduct a comprehensive test on the chemical composition and mechanical properties of the base metal of steel sheet pile. Including chemical composition analysis of steel, tensile and bending tests of components, locking strength test and elongation test. At least one tensile and bending test shall be conducted for each specification of steel sheet pile: two test pieces shall be conducted for every 20-50t steel sheet pile.
