Description

TECHNICAL FIELD

[0001] The application relates to the technical field of low-strain pile foundation detection devices, in particular to a low-strain pile foundation detection acceleration sensor coupling agent self-adding sleeve. BACKGROUND

[0002] In the low-strain pile foundation detection process, an acceleration sensor needs to be used to receive stress wave signals reflected by a pile foundation. In order to ensure the accuracy of the detection result, the sensor needs to be vertically placed on the end face of the pile foundation top. In order to reduce the influence of the pores between the sensor and the end face of the pile foundation on the stress wave conduction, coupling agent needs to be applied to the bottom of the sensor, and then the bottom of the sensor needs to be bonded to the end face of the pile foundation.

[0003] According to the low-strain pile foundation detection acceleration sensor coupling agent self-adding sleeve disclosed in Chinese Patent No. CN217923788U, the patent can automatically apply coupling agent to the acceleration sensor while protecting the acceleration sensor. In addition, the patent can assist the acceleration sensor in standing on the pile foundation to prevent the acceleration sensor from toppling on the pile foundation, and is suitable for protecting and assisting the use of the acceleration sensor in low-strain pile foundation detection.

[0004] However, the patent still has some shortcomings in actual use. Although the patent can automatically apply coupling agent to the acceleration sensor, it cannot control the discharge amount of the coupling agent. In addition, after the application of the coupling agent, the acceleration sensor needs to be moved out and bonded to the end face of the pile foundation before detection, which results in a large number of operation steps and low convenience. To solve the above problems, the application provides a low-strain pile foundation detection acceleration sensor coupling agent self-adding sleeve. CONTENT OF THE UTILITY MODEL

[0043] When detecting the pile foundation, place the limiting sleeve 1 on the top of the pile foundation, and clamp the fixed plate 601 and the movable plate 603 on the outside of the adjacent steel bars through the corresponding arc-shaped grooves 604. Rotate the inner hexagonal bolt 605 so that the fixed plate 601 and the movable plate 603 can clamp and position the steel bars. After positioning, insert the acceleration sensor body 4 into the inside of the detection port 3, and make the limiting protrusion 502 slide into the corresponding limiting groove 505 to limit the acceleration sensor body 4. Start the micro pump 205 to draw out the coupling agent in the storage tank 202, and record the flow passing through the flow valve 204. Make the quantitative coupling agent pass through the conduit 203 to the inside of the delivery pipe 206, and then fill between the bottom end of the acceleration sensor body 4 and the inside of the detection port 3 to complete the filling of the gap and the bonding of the acceleration sensor body 4.
