Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a device and method for correcting the horizontality of a cylindrical caisson. Background Art

[0002] With the development of caisson construction technology, the construction accuracy of cylindrical caissons has also increased. Therefore, precise control of levelness is a key factor in ensuring construction quality. In the construction of cylindrical caissons, most of them are buried underground and are large in size. During the caisson process, the levelness needs to be measured multiple times. The traditional measurement method usually sets multiple elevation control points on the upper part of the cylinder in advance. The elevation control points need to be made into a relatively flat surface layer and measured multiple times using equipment such as a level. This operation process is relatively cumbersome, the calibration cycle is relatively long, it is easily affected by the environment, there are measurement errors, and it is impossible to dynamically monitor the cylinder caisson process. The cylinder calibration time is relatively long, resulting in a relatively long construction period.

[0003] Therefore, there is an urgent need for a low-cost, high-reliability solution for the horizontality correction of caissons. Summary of the Invention

[0007] Preferably, a further technical solution of the present invention is: Preferably, each transparent rigid tube is provided with scale lines on its wall.

[0008] Preferably, two adjacent sections of the hose and the transparent rigid tube disposed between the two sections of the hose are connected via a three-way connector, and a sealing cap is provided at the upper end of each transparent rigid tube.

[0009] Preferably, the interior of the communicating vessel is filled with glass water.

[0010] The present invention also discloses a method for correcting the horizontality of a cylindrical caisson, the specific steps of which are as follows: S1. Divide the outer circle of the cylinder wall into several equal parts according to the rear elevation control point, and then mark the elevation points at the same height; S2. Assemble the communicating tube and fix the communicating tube as a whole to the outer wall of the cylinder by means of a clamp. The communicating tube is installed horizontally on the outer wall of the cylinder, and the transparent hard tube in the communicating tube corresponds to the elevation point one by one; S3. Pour glass water into the communicating vessel, stop pouring water when the liquid level in all transparent hard tubes reaches the elevation line, and then install the cover; S4. Use measuring instruments to observe the changes in the liquid level of the communicating vessel and adjust the horizontality of the cylinder wall in real time during the caisson sinking process.

[0011] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features: The present invention fixes the communicating vessel on the cylinder wall, injects glass water, and uses a measuring instrument to observe the liquid level changes in real time to adjust the cylinder in real time.

[0013] The present invention will be further described below in conjunction with specific embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0014] A device for leveling a caisson caisson includes a communicating vessel composed of several flexible tubes. A tee connector is provided between adjacent sections of flexible tubes. Two horizontal connections on the tee connector are connected to the flexible tubes at either end, while the other vertical connection of the tee connector is connected to the lower end of a transparent rigid tube. All flexible tubes and the transparent rigid tube are connected by the tee connector to form an annular communicating vessel. The transparent rigid tubes are positioned in a one-to-one correspondence with elevation points on the caisson wall.

[0015] In this embodiment, the hose is a transparent PVC hose, and the material of the transparent hard tube is also PVC.

[0016] Elevation lines are respectively set on the tube wall of the transparent rigid tube, and the elevation lines on all transparent rigid tubes are at the same height. In this embodiment, scale lines are set on the tube wall of the transparent rigid tube, and the scale line 200mm is used as the elevation line.

[0017] A blocking cap is provided at the upper end of each transparent rigid tube, and the blocking cap is used to seal the transparent rigid tube to prevent other debris from entering the interior of the transparent rigid tube.

[0018] The liquid injected into the communicating vessel is glass water, which is blue and easy to observe.

[0019] When installing the cylinder using the above-mentioned cylinder caisson level measuring device, proceed as follows: S1. Before caisson sinking, divide the outer circle of the cylinder wall into 8 equal parts according to the rear elevation control point, and then mark the elevation points of the same height corresponding to the equal division points.

[0020] S2. Assemble the hose, tee connector and transparent hard tube into a whole, and fix the connecting tube to the outer wall of the cylinder with a clamp. When fixing, pay attention to ensure the horizontality of the connecting tube as a whole, and set the transparent hard tube to correspond to the elevation point one by one.

[0021] S3. Inject windshield washer fluid into the top of one of the transparent rigid tubes. After the hose is filled with windshield washer fluid, stop injecting water after the windshield washer fluid rises to the 200mm mark in all the transparent rigid tubes. Then install a sealing cap on the upper end of each transparent rigid tube.

[0022] S4. A level meter or other measuring instrument is set up next to the installation position of the cylinder. By observing the horizontal line emitted by the measuring instrument and the changes in the liquid level in the transparent hard tube, the horizontality of the cylinder can be detected in real time to facilitate real-time adjustment.

[0023] The present invention utilizes the principle of communicating vessels, fixes the communicating vessels on the cylinder wall, injects glass water, and uses measuring instruments to observe the liquid level changes in real time to adjust the cylinder in real time, and measures the horizontality of the cylinder wall in real time, thereby reducing manual intervention and measurement frequency, reducing measurement errors, effectively improving the installation accuracy of the cylinder caisson, and significantly shortening the calibration cycle.
