CROSS HOLE SONIC INTEGRITY LOGGING (CSL) 跨孔声波测井完整性（移动通讯）

The Sonic Integrity Logging Sometimes called Ultrasonic Test , Sonic Test , Sonic Logging etc. 声波测井诚信有时被称为超声波测试 ， 声波测试 ， 声波测井等。 This test is performed to check integrity of concrete, locate defects and evaluate effectiveness of repair works on bored piles , caissons, barrettes and diaphragm walls and other concrete structures. 这个试验是要检查完整的混凝土中，定位缺陷，并评估成效，维修工程的钻孔桩，沉箱，壁板和地下连续墙及其他混凝土结构。

When cast-in-situ piles are constructed, the following defects may occur, hence the main objectives in the testing is to provide the clients/consultants information about:- 当机现浇桩的构造，以下缺陷可能发生的，因此主要目标是在测试是要提供客户/顾问信息： -

a) 一）	honeycombing due to inadequate vibration. 蜂窝由于缺乏足够的震动。
b) 二）	segregation due to over vibration and improper concrete placement methods. 隔离因过度振动和不正当的具体安置办法。
c) 三）	washout of cement due to groundwater flow. 水毁水泥由于地下水流。
d) 四）	cracks in pile shaft due to shrinkage. 裂缝桩身因收缩。
e) 五）	Inclusion of foreign material causing contamination of the concrete. 列入外国材料造成污染的混凝土。
f) 六）	necking of the pile due to collapse of sidewalls during withdrawal of the temporary casings. 缩颈的桩，由于倒塌的侧板，在撤退的临时套管。

This method on integrity testing requires prior pile preparation in that G.I. 这种方法对完整性测试需要事先桩准备在这附 pipes need to be installed together with the steel reinforcement bars. 喉管须安装与钢筋。 There is no limit in the depth where the pile profile can be logged. 有没有限制，在深度如桩剖面，可以登录。
