Embedded pile tip foundation detecting system

Abstract

The invention relates to an embedded pile tip foundation detecting system, which comprises an embedded pile, a first sealing rod, a second sealing rod, a detecting rod and a processor. The embedded pile is of a tapered tubular structure; reinforced synaptic junctions are arranged on the outer walls of the embedded pile; a small port end of the embedded pile is formed by an arc-shaped plate; the first sealing rod is in threaded connection with the embedded pile, and is provided with a disassembly head part and an expansion head; a stirring plate is arranged on the expansion head; the second sealing rod comprises an outer rod and a piston rod; the outer rod is provided with a discharge hole and a loading chamber; the piston rod is inserted into the loading chamber from the other end of the outer rod; an ultrasonic probe is arranged on one end of the detecting rod, and a wireless signal transmitting and receiving device is arranged on the other end of the detecting rod; and the processor is in signal connection with the wireless signal transmitting and receiving device. According to the embedded pile tip foundation detecting system provided by the invention, after a cast-in-place pile is casted, the first sealing rod is pulled out, so that a cut-through channel is formed. The embedded pile tip foundation detecting system can be used for detecting without the need for carrying out core drilling operation, and is very convenient to detect and simple to operate. After the detecting is completed, the second sealing rod is inserted into the cast-in-place pile to seal the cut-through channel, so that the structural strength of the whole cast-in-place pile can be improved.

Description

technical field [0001] The invention relates to the technical field of concrete structure building quality detection equipment, and more specifically, to a pre-embedded pile end foundation detection system. Background technique [0002] The cast-in-situ pile is a kind of infrastructure pile that is directly formed by pouring concrete in the ground. Since it is formed directly below the ground surface, the quality of the cast-in-place pile and the quality of the underlying foundation at the pile end cannot be observed intuitively. In order to ensure the construction quality, the quality of cast-in-situ piles is generally tested after concrete pouring, and the detection methods include low-strain method, ultrasonic method, and core-drilling method. Among them, low-strain method and ultrasonic method are non-destructive testing, which are suitable for pile body quality testing. The core drilling method is to detect the pouring quality of the pile body, the sediment at the bott...
