Description

Technical Field

[0001] The invention relates to the technical field of pile foundation engineering, and in particular to a support anchor horizontal displacement monitoring device. Background Art

[0002] Horizontal displacement monitoring used in infrastructure construction refers to the measurement of horizontal displacement of representative points of hydraulic structures and foundations using detection instruments. There are many horizontal displacement monitoring instruments currently in use, and they can be used at any construction site. After searching, there are many monitoring devices used for horizontal displacement of foundation pits. For example, CN218204609U discloses a horizontal displacement monitoring device for foundation pits.

[0003] Anchor support is one of the main ways to reinforce the foundation pit. However, in the construction of the foundation pit, the anchor positions are too complicated, and some construction sites are short, so the monitoring of the horizontal displacement of the anchor is completely ignored. Based on our company's long-term experience in large and small foundation construction, anchor monitoring is a very necessary and critical monitoring point. After searching, it was found that there is no monitoring device for the horizontal displacement of the anchor. During the construction of the foundation pit, our engineers used the existing monitoring instrument and directly improved it to form a kind of anchor horizontal displacement monitoring device that can be disassembled and assembled and flexibly rotated and adjusted in direction. It has been well applied to monitor the horizontal displacement of key anchor points, further ensuring the quality and safety of foundation construction. Summary of the invention

The slider 10 is connected to the limiting rod 11 on the side close to the limiting plate 12. The limiting plate 12 is provided with a through hole 13 on the side opposite to the limiting rod 11. The inner circle diameter of the through hole 13 is larger than the outer circle diameter of the limiting rod 11. When the through hole 13 is aligned with the limiting rod 11, the limiting rod 11 is pushed by the card bead 9, and the limiting rod 11 will pass through the through hole 13 until the card bead 9 is completely stuck in the annular card groove 6. Then the limiting rod 11 is automatically retracted by the elastic force of the spring 14. The bottom end of the bracket seat 3 is connected to the tripod 4, and the middle part of the bracket seat 3 is a hollow structure. The bracket seat 3 is connected to the adjustment seat 2 through the positioning rod 5 and the positioning groove 7.

The required command data (or including shooting data, etc.) can be input into the CPU by operating the buttons, and then the horizontal displacement of the anchor can be monitored by the cooperation of the transmitter and the receiver. The working principle of the total station is based on the principle of linear propagation and reflection of light. It measures the distance and angle between two points by transmitting and receiving electromagnetic wave signals, and then calculates the coordinates of the target point. It belongs to the existing monitoring technology and will not be detailed here.

[0028] Specifically, when the monitor body 1 is installed on the bracket seat 3, the block 15 is manually moved first, and then the block 15 and the limit plate 12 are moved around the outside of the adjustment seat 2 until the through hole 13 on the limit plate 12 is aligned with the scale mark 1301, and then the positioning groove 7 on the bottom adjustment seat 2 of the monitor body 1 is aligned with the positioning rod 5, and then directly pressed down after alignment, so that the annular groove 6 on the positioning rod 5 is engaged with the card bead 9, and then the block 15 is moved again to make the through hole 13 and the limit rod 11 misaligned, and the positioning rod 5 in the positioning groove 7 can be locked, so as to achieve the fixed installation of the monitoring body 1 of the total station between the bottom bracket seat 3.
