Description

Technical Field

[0001] The utility model relates to the technical field of caisson construction, in particular to a tilt detection and control device during the caisson sinking construction process. Background Art

[0002] Water conservancy and hydropower projects sometimes need to use caissons to construct temporary retaining walls. The inclination of caissons is one of the important factors affecting the sinking construction of caissons. Accurately understanding the angle and direction of sinking and inclination is an element to correctly guide the sinking construction of caissons. In particular, when it is necessary to accurately calculate the vertical component of the friction resistance of the well wall, the inclination angle and direction of the caisson must be obtained. During the caisson construction, the caisson is sunk in sections for installation. During the caisson construction, it is necessary to measure the inclination of the caisson for timely adjustment to avoid excessive inclination of the caisson. Affects the construction quality. The traditional inclination measurement is to connect the magnetic lines of force to the magnetic line of force plumb, and fix the magnetic lines of force at the top. The magnetic line of force plumb is automatically static, and then manually enter the well body to measure the horizontal distance between the magnetic line of force plumb and the blade foot of the caisson. The inclination angle of the caisson can be measured by trigonometric functions. However, this measurement method requires manual entry into the well body, and the magnetic line of force plumb is very easy to shake, which brings inconvenience to the measurement. In addition, the manually measured distance data is not accurate. Therefore, in view of the above problems, a tilt detection control device in the sinking construction process of the caisson is proposed. Utility Model Content

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

The outer sides of the pay-off drums are provided with lower pay-off lines, and the bottoms of the lower pay-off lines are fixedly connected to rangefinders.

[0010] During the caisson construction, the caisson is sunk in sections one by one for the installation of the caisson. During the caisson construction, it is necessary to measure the inclination of the caisson for timely adjustment to avoid excessive inclination of the caisson and affect the construction quality. The traditional inclination measurement is to connect the magnetic lines of force to the magnetic line of force plumb, and fix the magnetic lines of force at the top, through the automatic static state of the magnetic line of force plumb, and then manually enter the well body to measure the horizontal distance between the magnetic line of force plumb and the blade foot of the caisson.

The cooperation of the moving wheel and the guide wheel on the outside of the bottom of the rotating rod can ensure that the moving frame moves stably on the well wall and contacts the caisson body, and the outer side of the guide wheel contacts the caisson body. At this time, the moving assembly can be ensured to move stably on the outside of the caisson body. At this time, the inclination of the caisson can be detected in multiple directions to ensure the accuracy of the detection data, and the chain can drive the two sets of sprockets to rotate synchronously to ensure the stable movement of the moving wheel.

[0021] When measuring the inclination of the caisson, sometimes it is not possible to ensure that the measuring device is located at the lowest inclination.

[0035] The detection component 3 includes an adjustment frame 301, a second motor 302 and a rotating column 303. The outer side of the adjustment frame 301 is fixedly connected to the moving component 2. The inside of the adjustment frame 301 is fixedly connected to the second motor 302. The end of the main shaft of the second motor 302 is fixedly connected to the rotating column 303. Two sets of pay-off drums 304 are installed on the outer side of the rotating column 303.

[0036] During the caisson construction, the caisson is sunk in sections one by one for the installation of the caisson. During the caisson construction, it is necessary to measure the inclination of the caisson for timely adjustment to avoid excessive inclination of the caisson and affect the construction quality. The traditional inclination measurement is to connect the magnetic lines of force to the magnetic line of force plumb, and fix the magnetic lines of force at the top, through the automatic static state of the magnetic line of force plumb, and then manually enter the well body to measure the horizontal distance between the magnetic line of force plumb and the blade foot of the caisson, and the inclination angle of the caisson can be measured by trigonometric functions.

At this time, the two sets of lower pay-off lines 305 can not only quickly ensure the stability of the rangefinders 306, but also avoid manual entry into the well, thereby ensuring accurate measurement data without the need for manual downhole operation.

[0037] In this embodiment, the moving component 2 is used to stably move above the wall of the caisson 1, and the first motor 202 drives the walking component to rotate, and the rotating rod 203 drives the moving wheel 204 to rotate, thereby ensuring movement on the outside of the wall, and the two sets of lowering lines 305 can ensure the stable lowering of the rangefinder 306, which is used to ensure that the rangefinder 306 is quickly stationary and facing the wall, and the rangefinder 306 is an existing product, so its detailed structural principle will not be described in detail here.
