Abstract

Description
Technical Field
The invention relates to the field of a pile bottom detection device of a cast-in-place pile, in particular to a pile bottom sediment detection device of the cast-in-place pile.
Background
The deposited slag at the bottom of the cast-in-place pile is an important factor influencing the bearing capacity of the pile foundation. The excessive thick sediment can generate a 'soft cushion' effect, thereby reducing the bearing capacity of the pile and increasing the sedimentation of the pile body. Research shows that when the thickness of the sediment is increased and the strength is weakened, the maximum loss of the pile end resistance can reach more than 80%, and the thicker the sediment, the greater the loss of the bearing capacity of the pile foundation. The thickness of the sediment at the bottom of the cast-in-situ bored pile is used as an important index of the quality of formed holes, and the control and measurement measures are one of the key measures for ensuring the construction quality of the cast-in-situ bored pile and the bearing capacity of the pile foundation. Therefore, the current corresponding national standards and specifications have clear requirements on the sediment thickness control. When the pile mainly uses friction force, the allowable thickness of sediment is not more than 100mm, and when the pile mainly uses end bearing force, the allowable thickness of sediment is not more than 50 mm; for the end-supported pile, the thickness of the sediment at the bottom of the hole is not more than 50 mm. No greater than 150mm for friction type piles. The existing sediment thickness detection method is mainly a 'heavy hammer method', the sediment thickness is judged mainly by the hand feeling and experience of engineers, and the detection precision is difficult to guarantee.
