Embodiment 1

[0080] The sinking and floating construction method of the main tower of the bridge, method A includes the following steps:

[0081] 1) The base 4 and the main tower column 5-1 are manufactured in the workshop, and the main tower column 5-1 and the base 4 are transported to the set water area by floating, shipping, etc., as shown in figure 2 shown;

[0082] 2) if image 3 As shown, by injecting water into the bottom of the base 4 and the main tower column 5-1 or pumping water outwards, and / or adjusting the position of the base 4 and the main tower column 5-1 at the joints of the water surface by lifting equipment, the main The bottom of the tower column 5-1 is hinged with the base 4;

[0083] 3) if Figure 4 , Figure 5 As shown, the base 4 sinks by injecting water into the base 4, and the buoyancy makes the main tower column 5-1 rotate around the hinge center and gradually erect;

[0084] 4) if Figure 6-Figure 8 As shown, the main tower columns 5-1 are connected toget...

Embodiment 2

[0087] The sinking and floating construction method of the main tower of the bridge, method B includes the following steps:

[0088] 1) The base 4, the lower main tower column 5-1A and the upper main tower column 5-1B are manufactured in the workshop and transported to the set water area by means of floating or shipping;

[0089] 2) if Figure 9 As shown, by injecting water into the bottom of the base 4 and the lower main tower column 5-1A or pumping water outward, and / or adjusting the position of the base 4 and the lower main tower column 5-1A on the water surface at the joints of the water surface by lifting equipment, etc. Hinge the bottom of the lower main tower column 5-1A with the base 4;

[0090] 3) if Figure 10 As shown, by injecting water into the top of the lower main tower column 5-1A and the upper main tower column 5-1B or pumping water outwards, and / or adjusting the lower main tower column 5-1A and the upper main tower column 5 by lifting and other equipment -...

Embodiment 3

[0096] Such as Figure 16 As shown, the bridge main tower ups and downs construction method containing oblique arm 6 comprises the following steps:

[0097] 1) The base 4, the main tower column 5-1, the oblique arm 6, and the connecting rod 7 are manufactured in the factory, and are transported to the set water area by means of floating or shipping;

[0098] 2) if Figure 17 As shown, one end of the connecting rod 7 is hinged with the top of the oblique arm 6, and the bottom of the oblique arm 6 is hinged with the base 4;

[0099] 3) if Figure 18 As shown, the bottom of the main tower column 5-1 is hinged with the base 4;

[0100] 4) if Figure 19 As shown, the top of the main tower column 5-1 is hinged with the other end of the connecting rod 7;

[0101] 5) if Figure 20 , Figure 21 As shown, the top of the main tower column 5-1 is hinged to form the main tower 5, and then floats up.

Abstract

The invention discloses a sinking and floating construction method for a main tower of a bridge. The method comprises a method A or a method B. The method A comprises the following steps: (1) manufacturing a base 4 and main tower columns 5-1 at a construction site; (2) hinging the bottoms of the main tower columns 5-1 to the base 4; (3) injecting water into the base 4 to make the base 4 sink and the main tower columns 5-1 stand; (4) connecting all the main tower columns 5-1 to form a main tower 5. The sinking and floating construction method has the advantages that after being manufactured at the construction site, the main tower columns 5-1 and the base 4 are transported to a set water domain in a floating manner to realize posture adjustment, assembling and construction under the hydraulic power. Therefore, the construction period can be shortened, the labor intensity can be reduced, and the construction quality can be guaranteed.

Description

technical field [0001] The invention relates to a bridge main tower sinking and floating construction method, which belongs to the technical field of bridge construction. Background technique [0002] In the construction of the existing bridge main tower, the bridge main tower is poured or assembled on site, so the construction period is long, the labor intensity is high, and the construction quality is difficult to guarantee. Contents of the invention [0003] The present invention proposes a sinking and floating construction method for the main tower of a bridge. Its purpose is to overcome the defects in the prior art. The main tower column and the base are manufactured in the workshop, and the attitude, assembly and installation are adjusted by floating to the set water area with hydraulic power. construction. [0004] Technical scheme of the present invention: bridge main tower ups and downs construction method, it is characterized in that comprising A method or B met...
