| 1钢筋保护层厚度检测 |
1 Detection of reinforcement protective layer thickness |
| 一般采用测量仪对钢筋保护层厚度进行无损检测，探头发射电磁信号，保护层中钢筋产生二次感应磁场，由探头接收，通过仪器处理，得到钢筋保护层厚度或钢筋直径的测量值。 |
Generally, the measuring instrument is used to detect the thickness of the protective layer. The probe emits the electromagnetic signal, and the steel bar in the protective layer produces the secondary induction magnetic field, which is received by the probe and processed by the instrument to get the measurement value of the thickness of the protective layer or the diameter of the steel bar. |
| 2、混凝土强度回弹法检测 |
2, the concrete strength rebound method detection |
| 使用一把具有弹簧驱动的重锤穿过传力杆，混凝土表面上进行作用，然后测量重锤反弹回来的距离，把弹力距离和弹簧初始长度的比值来推定混凝土强度。 |
| Using a heavy hammer with a spring drive through the transmission bar, the concrete surface, then measure the distance of the hammer back, and ratio the elastic distance to the initial length of the spring to infer the concrete strength. |
3、植筋拉拔检测 |
| 3, planting tendon drawing test |
植筋拉拔检测就是现场检测锚固体的锚固力，按每种植筋锚固力的0.1%且不少于3根进行确定，一般进行植筋48-72小时后采用拉力计对所植钢筋进行拉拔试验加载方式。 |
| The pulling test of the planting bar is to detect the anchorage force of the anchor solid on site. It is determined according to 0.1% of the anchorage force of each planting bar and no less than 3 roots. Generally, the planting bar adopts the pulling test loading method after 48-72 hours. |
4、楼板厚度检测 |
| 4, floor thickness detection |
楼板厚度对工程结构安全有非常重要的作用，楼板厚度检测在工程质量检中是必检项目之一，一般采用电磁原理检测法进行无损检测，发射探头和接收探头分别置于被测楼板的表面和底面，发射探头发出电磁信号，接收探头接收经衰减的磁场信号，仪器处理后得到楼板厚度检测值。 |
| Floor thickness has a very important role in engineering structure safety, floor thickness detection is one of the engineering quality inspection project, generally adopts the principle of electromagnetic detection method for nondestructive testing, transmitting probe and receiving probe on the surface and bottom of the floor, transmit the probe from electromagnetic signal, receive the probe received the attenuation of magnetic field signal, the instrument get floor thickness detection value after processing. |
5、混凝土强度钻芯法检测 |
| 5, concrete strength drilling core method detection |
钻芯法是利用专用钻机在结构混凝土中钻取芯样，以检测混凝土强度或观察混凝土内部质量的方法，应该根据检验批的容量来确定取样的数量，需要注意的是对结构混凝土造成局部损伤。 |
| The core drilling method is the use of special drilling rig to drill core samples in the structural concrete to detect the strength of concrete or observe the internal quality of the concrete, the number of sampling should be determined according to the capacity of the inspection batch, which needs to pay attention to the local damage to the structural concrete. |
