[0026] The application will be described in further detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, and not limit the utility model. In addition, it should be noted that, for the convenience of description, only the parts related to the utility model are shown in the drawings.

[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and embodiments.

[0028] Referring to Figs. 1 to 3 The utility model provides a bored pile sediment thickness measuring device, include: mobile support 1, electric telescopic rod 2, puncture cone 3, controller.

[0029] In the embodiment, the mobile support 1 is arranged at the orifice of the bored pile hole.

[0030] The length of the electric telescopic rod 2 can be automatically adjusted. The electric telescopic rod 2 is arranged vertically. The electric telescopic rod 2 has opposite fixed end and telescopic end. The fixed end of the electric telescopic rod 2 is detachably installed on the mobile support 1. The telescopic end of the electric telescopic rod 2 is installed with displacement sensor.

[0031] The puncture cone 3 is installed on the telescopic end of the electric telescopic rod 2. The puncture cone 3 is installed with pressure sensor and ultrasonic sensor. The pressure sensor is installed on the top of the puncture cone.

[0032] The puncture cone is a circular cone or a regular polygonal cone.

[0033] The controller is signal connected to the electric telescopic rod 2, displacement sensor, pressure sensor and ultrasonic sensor. The mobile support 1 is installed with display. The display is connected to the controller.

[0034] When the cast-in-place pile sediment thickness measuring device detects the thickness of the sediment in the pile hole of the cast-in-place pile, the movable support is moved to the orifice of the pile hole of the cast-in-place pile, so that the planar center of the movable support is arranged on the central axis of the pile hole. The fixed end of the electric telescopic rod is installed on the movable support, so that the telescopic end of the electric telescopic rod extends into the pile hole. The electric telescopic rod is turned on, and the electric telescopic rod is elongated downward, driving the puncture cone to the bottom of the pile hole. During the puncture cone downward process, the displacement sensor collects the telescopic length of the electric telescopic rod in real time, the pressure sensor collects the pressure value of the surface of the puncture cone in real time, and the ultrasonic sensor adopts non-contact detection, analyzes the reflection wave time difference of the sediment layer by emitting ultrasonic waves and receiving reflected signals, and determines the sediment thickness.

[0035] The controller obtains the telescopic length of the position sensor and calculates the depth of the puncture cone.

[0036] The controller obtains the pressure value of the pressure sensor, calculates the first sediment thickness based on the depth of the puncture cone when the pressure value of the pressure sensor to the upper surface of the sediment layer and the depth of the pile hole, the first pressure value of the pressure sensor in water is the smallest, and the second pressure value in the sediment is greater than the first pressure value. When the puncture cone touches the bottom, the third pressure value of the pressure value collection is greater than the second pressure.

[0037] The controller obtains the signal of the ultrasonic sensor and obtains the second sediment thickness. Based on the error range of the first sediment thickness and the second sediment thickness, it is determined whether the sediment thickness detection is effective. When the error range of the first sediment thickness and the second sediment thickness is less than the threshold range, it is determined that the current sediment thickness detection is effective. The average of the first sediment thickness and the second sediment thickness can be used as the specific sediment thickness. When the error range of the first sediment thickness and the second sediment thickness is greater than the threshold range, it is determined that the current sediment thickness detection is invalid.

[0038] The controller displays the obtained various data on the display for the construction personnel to intuitively understand the specific data.
