Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and specifically to a device for detecting the grouting height of cast-in-place piles. Background Technology

[0002] In pile foundation grouting projects, pile length is a critical design parameter. Insufficient pile length can affect the bearing capacity of the pile foundation, thereby jeopardizing the structural safety of the entire foundation pit. Traditional measurement methods, such as using measuring ropes, suffer from low accuracy and susceptibility to human factors. Secondly, during the grouting process, precise control of the concrete pouring height is crucial. Excessive pouring height leads to concrete waste; insufficient pouring height may result in insufficient pile length. Depth measuring instruments can monitor depth changes in real time during the grouting process, allowing construction personnel to accurately control the amount and height of concrete poured, improving the quality of pile foundation formation. To address these issues, a laser depth measuring device can be designed to accurately measure the depth of the pile hole, ensuring that the poured pile length accurately reaches the design length, providing reliable assurance for project quality. It can also monitor depth changes in real time during the grouting process.

[0003] Traditional measurement methods include the string method and the acoustic method. The string method involves placing a string inside the pile hole and relying on gravity to reach the bottom to measure the grouting depth. However, this method is susceptible to the influence of the concrete inside the hole; the string may become entangled or sink too deeply, leading to inaccurate results. Furthermore, the string method requires manual operation, resulting in low efficiency, and is difficult to perform in deep pile construction. The acoustic method, on the other hand, has limited measurement accuracy, requires expensive equipment, and is complex and not suitable for rapid measurement. Utility Model Content

[0030] Reference Figures 1 to 4 As shown, this utility model provides a pile body grouting height detection device for cast-in-place piles, including: a support beam 1, a tripod 2, a laser rangefinder 3, and a controller.

[0031] In this embodiment, the support beam 1 is elongated. The support beam 1 has two opposite ends along its length and two opposite sides along its width. The support beam 1 is positioned across the pile hole 4 of the cast-in-place pile. The support beam 1 is positioned above the opening of the pile hole 4. A level 11 and an alarm are mounted on the support beam 1.

[0032] As a preferred embodiment, the level 11 is a bubble level 11.

[0033] There are two tripods, tripod 2. The height of tripod 2 is adjustable. Tripod 2 is a support used to stabilize the camera; its specific structure is existing technology and will not be described in detail here.

[0034] Two tripods 2 are respectively installed on opposite sides of the opening of the pile hole 4. The two tripods 2 are positioned below both ends of the support beam 1. A groove is formed on the top platform 22 of one tripod 2. A ball head 12 is formed at one end of the support beam 1. In this embodiment, the ball head 12 is connected to the bottom of one end of the support beam 1 via a support rod. The ball head 12 is rotatably accommodated in the groove.

[0035] Two electrically operated telescopic components 21 are vertically mounted on the top platform 22 of the other tripod 2. The tops of the two electrically operated telescopic components 21 are hinged to the other end of the support beam 1. The two electrically operated telescopic components 21 are arranged along the width direction of the support beam 1.

[0036] See Figure 4 As shown, the ball head 12 is centrally located at one end of the support beam 1, that is, the ball head 12 is centrally located in the middle of the support beam 1 in the width direction. Two electric telescopic components 21 are symmetrically arranged on opposite sides of the ball head 12.

[0037] In a preferred embodiment, the electric telescopic component 21 is an electro-hydraulic actuator. The electro-hydraulic actuator has a fixed end and a telescopic end. The fixed end of the electro-hydraulic actuator is fixed to the bearing platform 22, and the telescopic end of the electro-hydraulic actuator is universally connected to the bottom of the support beam 1 via a ball joint.

[0038] The laser rangefinder 3 is installed on the support beam 1 and aligned with the pile hole 4.

[0039] The controller is connected to the electric telescopic component 21, the alarm, and the laser rangefinder 3.

[0040] In a preferred embodiment, the base 22 of the tripod 2 is equipped with a locking element 23 for locking the ball head 12. After the support beam 1 is leveled by controlling the extension and retraction of the electric telescopic component 21 via the controller, the locking element 23 is installed on the base 22 to lock the ball head 12.

[0041] In this embodiment, combined with Figure 3 As shown, the bearing 22 has a threaded hole communicating with the groove. The locking member 23 has an external thread. The locking member 23 is screwed into the threaded hole and extends into the groove. One end of the locking member 23 presses against the ball head 12.

[0042] Continue reading Figure 3As shown, the shape and size of the groove are adapted to the shape and size of the ball head 12. In this embodiment, the upper part of the ball head 12 extends outside the opening of the groove. The groove depth is less than the diameter of the ball head 12 but greater than the radius of the ball head 12.

[0043] This invention relates to a pile grouting height detection device for cast-in-place piles, addressing existing problems by designing a laser depth measuring device for the pile body. The device comprises two tripods, a support beam, an alarm capable of broadcasting voice commands, and a laser rangefinder.

[0044] Before pouring concrete into the cast-in-place pile, two tripods are inserted into the ground beside the pile hole opening. A support beam is mounted on the two tripods, and the height of two electrically operated telescopic components is controlled by a controller to adjust the level of the support beam. The levelness of the support beam is visually reflected by a level. After the support beam is leveled, the locking mechanism is rotated to press against the ball head, thus locking the ball head in the groove. Then, a laser rangefinder is installed in the middle of the support beam and aligned with the pile hole. At this point, the entire device is installed.

[0045] The installation process of the pile body grouting height detection device for cast-in-place piles is simple, easy to operate, and saves time and effort.

[0046] This utility model discloses a pile grouting height detection device for cast-in-place piles, equipped with a display screen and data transmission interface connected to a controller. It can display the measurement data from a laser rangefinder on the screen in real time. During this process, a voice alarm remains active; when the data on the display screen approaches the designed value, the controller activates the alarm, triggering a real-time alert. Construction personnel can intuitively understand the changes in grouting depth, facilitating timely adjustments to the construction plan.

[0047] This utility model discloses a compact and portable device for detecting the grouting height of cast-in-place piles. Construction workers can perform measurements anytime and anywhere on the construction site, without being limited by location. Furthermore, the low-power design of this device allows it to operate for extended periods, meeting the needs of construction sites.
