Full-automatic cast-in-place pile bottom sediment monitoring device

Abstract

The utility model is suitable for the technical field of cast-in-place pile bottom sediment monitoring, and provides a full-automatic cast-in-place pile bottom sediment monitoring device which comprises a space reserving box, a crawler belt, a first motor, a second motor, an ultrasonic sensor, a sediment monitoring device, a pulley and a thrust wheel. The device is placed at the pile bottom, and the first motor and the second motor can immediately start to automatically operate. The speed reducer can control the rotating speed of the first motor and the rotating speed of the second motor according to a preset program, and therefore pile bottom walking and steering are achieved. After the probe reaches the preset position, the pulley located in the space reserving box starts to rotate, and the extension of the spring pushes the probe into sediment at the bottom of the pile. Meanwhile, the pressure sensor can monitor bounce data of the spring in real time. When the probe downwards probes an original soil layer, the pulley rotates to pull the probe, and the thickness of sediment at the bottom of the pile is monitored according to the number of turns of rotation of the pulley.

Description

Technical Field

[0001] This invention relates to the field of pile bottom sediment monitoring technology for cast-in-place piles, and provides a fully automatic pile bottom sediment monitoring device. Background Technology

[0002] In engineering, cast-in-place piles are an important foundation type, widely used in various geological conditions and building types. During the construction of cast-in-place piles, the issue of sediment at the pile bottom directly affects the pile's bearing capacity. Sediment at the pile bottom refers to the mud, sand, and other debris that settles at the bottom of the borehole after the pile is formed. If the thickness of the sediment cannot be effectively controlled and accurately monitored, it will seriously affect the quality of the cast-in-place pile, thereby threatening the safety of the entire building structure.

[0003] In large-scale projects, the number of cast-in-place piles is numerous. Traditional sediment monitoring methods not only require a significant manpower investment but are also inefficient, prolonging the construction period. In complex geological conditions, repeated measurements are necessary, and inaccurate sediment monitoring results can lead to quality problems with the cast-in-place piles. Subsequent repairs or reinforcement will result in substantial economic losses, increasing not only labor costs but also potentially other related costs due to construction delays. Utility Model Content

[0004] In response to the ever-expanding scale of various projects and the increasing demands for construction quality, traditional manual monitoring methods are insufficient to meet the needs of efficient and accurate construction. The purpose of this utility model is to overcome the above shortcomings and provide a fully automatic sediment monitoring device that can acquire sediment thickness data in real time and continuously, which helps construction personnel to keep abreast of the sediment situation at the bottom of the pile.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fully automatic pile bottom sediment monitoring device includes a space reserved box, a track, a first motor, a second motor, an ultrasonic sensor, a sediment monitoring device, pulleys and support rollers;

[0007] Two symmetrical drive wheels are provided on both sides of the space reserved box, and the drive wheels on both sides of the space reserved box are respectively engaged with the track;

[0008] The first motor and the second motor are located inside the space reserved box, and the two motors are connected through the transmission wheels on both sides of the front of the space reserved box;

[0009] The support roller is located inside the space-reserved box, and is connected through the drive wheels on both sides of the rear of the space-reserved box; the support roller is used to support the tracks and ensure that the device moves smoothly on the pile bottom.

[0010] The ultrasonic sensor is located at the front end of the space-reserved box and is fixedly connected to it. It is also connected to two motors via a wired connection. The ultrasonic sensor controls the first and second motors to achieve steering and path planning for the device.

[0011] The sediment monitoring device is located inside the space reserved box and is fixedly connected to the bottom of the space reserved box. The sediment monitoring device includes a pressure sensor, a spring and a probe.

[0012] The pulley is located inside the space reserved box. The pulley is connected to the second motor through a steel strand. The pulley-connected motor provides the upward pulling force for the probe.

[0013] In a further technical solution, a support shaft is fixedly installed in the middle of the space reserved box, and the support shaft is connected to the pulley through a bearing.

[0014] A further technical solution is that the sediment detection device is equipped with a spring inside, which provides downward pressure to the probe to ensure that the probe can penetrate into the sediment layer; a pressure sensor is provided on the upper part of the sediment detection device, and a probe is provided inside the sediment detection device, with the bottom of the pressure sensor fixedly connected to the upper part of the spring.

[0015] In a further technical solution, a steel strand is fixedly connected to the top of the probe, the steel strand is connected to a pulley track, and the pulley is located at the top of the sediment detection device; the pulley is connected to the probe through the steel strand.

[0016] A speed reducer is installed on both sides of the first motor and the second motor, and the speed reducer controls the speed of the first motor and the second motor.

[0017] Below the sediment monitoring device, there is an opening inside the space reserved box to facilitate the operation of the probe monitoring device.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] This invention provides a fully automatic pile bottom sediment monitoring device. By placing the device at the pile bottom, a first motor and a second motor can immediately begin automatic operation. A reducer can control the speed of the first and second motors according to a pre-set program, thereby enabling pile bottom movement and steering. After reaching a preset position, a pulley located in a pre-reserved space box begins to rotate, and the extension of a spring pushes a probe into the sediment at the pile bottom. Simultaneously, a pressure sensor monitors the spring's rebound force data in real time. When the probe reaches the original soil layer, the pulley pulls the probe by rotating, and the thickness of the sediment at the pile bottom is monitored by the number of pulley rotations. Furthermore, another beneficial effect of this invention is that an ultrasonic sensor can be used to control the first and second motors to achieve steering through independent drive, and to monitor the sediment thickness at the pile bottom in real time according to a planned path. This provides a more accurate and efficient means of monitoring the sediment condition of the cast-in-place pile.
