Description

Technical Field

[0001] The invention relates to caisson construction, and in particular to a caisson inclination monitoring and deviation correction device. Background Art

[0002] Caisson is a common underground engineering construction method, which is widely used in construction, mining, water conservancy and other fields. However, during the caisson construction process, due to geological conditions, improper construction operations and other reasons, the caisson often tilts. Caisson tilt not only affects the construction progress and quality, but also may bring certain safety risks to the surrounding environment. Therefore, it is very important to take correct and effective corrective measures in a timely manner.

[0003] At present, there are two main ways to correct the deviation of caissons. One is to use heavy pressure on the higher side to make it sink quickly. This method usually requires heavy machinery to lift iron blocks (or concrete blocks, sandbags) or heavy machinery to directly apply pressure on one side of the caisson. However, this method is inconvenient to operate, and it is troublesome for heavy construction machinery to enter and exit the site, and the construction cost is also high. The other method is a correction method that combines the partial excavation method with the one-side support pad method, that is, excavating the side of the well with a higher blade foot and adding a support pad on the side with a lower blade foot. As the caisson sinks, the high side blade foot can be gradually lowered. This method is often not effective, and if multiple corrections are required during the caisson construction process, this method will greatly increase the construction period. If the caisson is seriously tilted, it is often difficult to take effective measures to correct it.

[0004] In addition, the monitoring methods currently used for caisson sinking are relatively conventional, and the monitoring frequency is relatively high, generally every few days. Caissons are prone to tilt during the sinking process, and conventional monitoring methods are difficult to reflect the tilt of the caisson in a timely manner. Once the degree of tilt exceeds the design requirements, it will be difficult to take effective measures to correct the deviation. Summary of the invention

[0048] like Figure 7 As shown, in order to provide support force for the pressure device 22 and the tension device 23 and limit their upward or downward movement, the ring beam 21 is fixed to the stratum by anchor rods, and an inverted T-shaped slide groove 211 is arranged on the ring beam 21, and third rollers are respectively installed at the bottom of the pressure device 22 and the tension device 23, and the third rollers are placed in the slide groove 211, and the pressure device 22 and the tension device 23 are slidably connected to the ring beam 21 via the third rollers.

[0049] The specific construction steps of using the present invention to monitor and correct the tilt of the caisson are as follows:

[0050] (1) Before the construction of the caisson 3, a tilt monitoring device 1 is installed on the side wall of the caisson in multiple directions. The number of the installed tilt monitoring devices 1 is determined according to the shape, size and other characteristics of the caisson 3. The more the number of installed tilt monitoring devices 1 is, the more comprehensive the monitoring of the tilt of the caisson in all directions can be.

[0051] Working principle of the tilt monitoring device 1: The connecting ear seat of the inclined rod 15 of the tilt monitoring device 1 is connected and fixed to the side wall of the caisson by nails or bolts, and the installation elevation of each tilt monitoring device 1 is kept consistent. The mounting seat 11 of the tilt monitoring device 1 is fixed to the soil layer outside the caisson by bolts 112 or steel nails to prevent it from settling and moving left and right. The upper part of the bolt 112 or steel nail is connected to the support plate 111 by a leveling nut 113. The flatness of the tilt monitoring device 1 can be adjusted by the leveling nut 113. The installation of the tilt monitoring device 1 should be horizontal and without tilt. When the caisson 3 is officially constructed and sunk, the forward and backward tilting of the sinking height of the caisson 3 will cause the inclined rod 15 of each inclination monitoring device 1 to move along the second support 141, and its sinking height and forward and backward tilting degree can be reflected by the second scale 137 and the third scale 147 of each inclination monitoring device 1. For example, when the settlement heights of the caisson 3 in each direction are the same and there is no deviation, the scales of the inclination monitoring devices 1 in each direction should remain consistent; if it tilts forward or backward, the forward and backward movement amplitude of the inclined rod 15 of the inclination monitoring device 1 located in the front and rear will be larger, so that the indication value of the third scale 147 of the inclination monitoring device 1 located in the front and rear will increase, and correspondingly, the forward and backward movement amplitude of the inclined rod 15 of the inclination monitoring device 1 located on the left and right will be larger, so that the indication value of the second scale 137 of the inclination monitoring device 1 located on the left and right will increase; if the caisson 3 tilts to the left or right, The inclined rod 15 of the tilt monitoring device 1 at the rear will move left and right, and the indication value of the second scale 137 of the tilt monitoring device 1 located at the front and rear will increase. Correspondingly, the inclined rod 15 of the tilt monitoring device 1 located on the left and right will also move left and right, and the indication value of the third scale 147 of the tilt monitoring device 1 located on the left and right will increase, reflecting the left and right movement of the caisson 3; if the caisson 3 rotates in a certain direction, the inclined rod 15 of each tilt monitoring device 1 will drive the left and right moving parts 13 and the front and rear moving parts 14 to rotate as a whole, and the rotation situation can be reflected by the first scale 125 (Note: the setting of the rotating part 12 is to realize the rotation function. The first spring 123 of the rotating part 12 is connected to the inner and outer rings respectively. The inner ring is fixed to the bottom plate of the left and right moving parts 13, and the outer ring is fixed to the support plate 111 of the mounting seat 11. The first spring 123 can provide a certain damping when the inner ring 21 rotates).Since the movement of the inclined rod 15 of the tilt monitoring device 1 and the overall rotation of the left-right moving component 13 and the front-back moving component 14 are achieved through the rollers at the bottom, and since the sliding friction of the rollers is relatively small, the provision of the first, second, and third springs increases the damping of the front-back movement, left-right movement, and rotation thereof, thereby preventing the tilt monitoring device 1 from moving randomly under the action of other external forces. In addition, the second spring 135 is provided on the first guide rod 133, and the third spring 145 is provided on the second guide rod 144, so that the second spring 135 and the third spring 145 can be compressed along a fixed direction, thereby improving the stability and accuracy of the monitoring data.

[0052] (2) When the caisson 3 tilts, the pressure device 22 and the tension device 23 should be activated immediately. The ring beam 21 is fixed to the ground through anchor rods, and the pressure device 22 and the tension device 23 are installed in the inverted T-shaped slide groove of the ring beam 21 through roller sliding. The ring beam 21 mainly provides support for the pressure device 22 and the tension device 23 when they are working, limiting their upward or downward movement.

[0053] The working principle of the pressure device 22 and the tension device 23 is as follows: the inclination of the caisson 3 will inevitably cause the caisson to be higher in one direction and lower in another direction. The higher and lower situations can be reflected by the inclination monitoring device 1. The principle of caisson correction is to apply pressure on the higher side through the pressure device 22 to make it sink quickly (achieved by applying pressure through the telescopic cylinder of the pressure device 22), and to apply an upward pulling force on the lower side through the tension device 23 to slow down its sinking speed (achieved by applying pulling force through the lifting device 233 of the tension device 23), so that the final settlement height of the caisson 3 in all directions remains consistent. Before correction, the lifting rod 2331 of the tension device 23 is connected to the outer wall of the caisson through the connecting ear seat. After the correction is completed and the connecting ear seat is removed, the opening of the caisson connection position should be blocked. When the tension device 23 is under construction, the caisson 3 will exert a large vertical downward force on it. The role of the lifting support rod 232 is to increase the support for the tension device 23 to prevent it from being damaged. The lifting support rod 232 is in contact with the ground only when it is working, and rises to a certain height from the ground when it is not working. The lifting rod 2331 and the lifting support rod 232 of the tension device 23 apply forces through motors respectively. The pressure device 22 and the tension device 23 can move to each position of the caisson 3 on the ring beam 21, and the selection of their working positions should be determined according to the movement of the inclined rod 15 of the tilt monitoring device 1 in each direction. Whether the caisson 3 has been corrected should be observed through the tilt monitoring device 1. When the scale values ​​of each tilt monitoring device 1 are the same or return to their original positions, it proves that the correction is completed.

[0054] The above is only a specific implementation scheme of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the art can make many possible changes and modifications to the technical scheme of the present invention by using the technical content disclosed above without departing from the scope of the technical scheme of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical scheme of the present invention should fall within the protection scope of the technical scheme of the present invention.
