Specific implementation

[0029] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Please refer to Figures 1-8 The utility model provides a technical scheme: steel sheet pile inclination control device, including fixed seat 2, the support 3 of setting in the upper end of fixed seat 2 and the support block 5 for fixing for the steel sheet pile 1 of setting in the side of support 3 away from fixed seat 2, still include:

[0031] Adjusting device 4, setting in support 3 and being connected with support block 5, for the installation angle of adjusting steel sheet pile 1;

[0032] Adjusting device 4 includes:

[0033] Base 41, setting in support 3;

[0034] Adjusting mechanism, setting in the side of base 41 away from support 3, for adjusting the installation position of support block 5;

[0035] Top plate 48, setting in the side of adjusting mechanism away from base 41, for supporting support block 5.

[0036] It should be noted that in operation, the foundation pit cofferdam uses the Larsen IV type steel sheet pile 1 as the main material, and uses a vibrating pile driver for pile sinking construction. During the construction process, due to the large gap between the locking ports of the steel sheet pile 1, the upper end of the steel sheet pile 1 will always tilt away from the first steel sheet pile 1 during insertion and driving. Therefore, every four or five steel sheet piles 1 are driven, the inclination of the steel sheet pile 1 is controlled to be within 1% through measurement, and when the inclination exceeds the limited inclination, it should be corrected. When the steel sheet pile 1 deviates too much, only the method of multiple correction can gradually reduce the deviation. First, use the inclinometer 6 to measure the inclination angle of the Larsen steel sheet pile 1, and vertically install three inclinometer sleeves at the same interval on the inside of the steel sheet pile 1. After connecting the inclinometer 6 device, inserting the inclinometer 6 probe and debugging, the inclination angle of the steel sheet pile 1 is measured. After confirming that the steel sheet pile 1 insertion and driving construction deviates, the device is transported to the construction site, then the support 3 is connected to the adjusting device 4, the adjusting mechanism is slowly rotated, the top plate 48 drives the upper side of the steel sheet pile 1 to be pushed, and the steel sheet pile 1 is deviated to the position close to the first vertical steel sheet pile 1. Every 2° adjustment, the steel sheet pile 1 is measured again by the inclinometer 6, and then the steel sheet pile 1 is adjusted by the adjusting device 4. Repeat the above steps until the inclination of the steel sheet pile 1 is controlled within 1% as shown by the three inclinometer 6 instruments. At this time, the outside of the steel sheet pile 1 for correction is filled and the connected locking port is welded to ensure that the steel sheet pile 1 will not deviate again after the mold is removed. (Note that the welding thickness of the upper end should be wider and gradually decreased downward), after the welding work is completed, a layer of lubricating oil is applied between the support block 5 and the locking port to prevent the support block 5 from being stuck with the steel sheet pile 1 and unable to be removed. Then find a suitable angle to rotate the fixed seat 2 and remove the support block 5. After the above work is done, the support 3 can be gradually retracted and the linking device at both ends of the support 3 is disconnected. The disassembly work of the device is completed. Through the setting of the device, the inclination correction work of the Larsen steel sheet pile 1 of the deep foundation pit cofferdam is completed, the overall stability of the cofferdam steel sheet pile 1 system is effectively improved, the safety risk of the construction personnel is reduced, and a complete cofferdam construction guarantee system is constructed.

[0037] In an embodiment, the adjusting mechanism includes a rotating plate 45 rotatably arranged on the base 41 and a moving plate 44 movably arranged on the base 41. The rotating plate 45 and the moving plate 44 are arranged in cross and connected through a rotating shaft 47.
