arduino with multi adxl345

i use 3 adxl345 with HCF4052B Multiplexer to arduino uno
i want to read the value of adxl345
my connection i2c:
GND (For 3 adxl345) to Gnd arduino
VCC ((For 3 adxl345)) to 3v ardiono
scl ((For 3 adxl345) to A5
sda (For 3 adxl345) to A4
cs (For 3 adxl345) is connect to HVF4052B (0y,2y,3y)
Y Common of HCF4052B is connect to 3v arduino
i want to give 3v to each cs in order to read the value of adxl345
my probelem is the value is of 1 adxl345 and not changed

this picture for the diagram of my circuit
