[0021] A construction method of a bridge rotating closure installation structure, characterized in that it comprises the following steps:

[0022] S1: Build a temporary platform on the side of the bridge pier, install bridge vibration reduction bearings and a rotating mechanism on the connecting table located at the center, fix the beam body and the other end of the rotating mechanism, install a continuous jack, a hydraulic pump station and a control console, and connect the continuous jack and the rotating mechanism;

[0023] S2: Start the continuous jack through the control console, and rotate the beam body to the specified position through the rotating mechanism;

[0024] S3: Install several groups of bridge vibration reduction bearings on the corresponding connecting tables, and fix the two ends of the bridge vibration reduction bearings on the bridge piers and the beam bodies respectively through bolts;

[0029] By pouring, the rotating mechanism is poured on the bridge pier and fixed as a whole, and at the same time, the normal use of the bridge vibration reduction bearing is not affected.

[0030] The working principle and beneficial effects of this solution are as follows:

[0031] In operation, the continuous jacks are controlled via a control console, which drives the beam to rotate and descend through a rotating mechanism. When the beam reaches the designated position, the bridge vibration damping bearings are bolted to the beam. The bolts used to secure the rotating mechanism to the beam are then removed. The rotating mechanism is then restarted to separate the second fixing seat from the beam. The bolts used to secure the rotating mechanism to the pier are then removed, and the first and second fixing seats are disassembled into first and second small pieces. The entire rotating mechanism is then disassembled and removed. After the beam rotation is complete, only the rotating mechanism needs to be disassembled; it is not necessary to cast the rotating mechanism into the pier, thus reducing the bridge construction period and improving construction efficiency. Alternatively, the rotating mechanism can be cast directly onto the pier without disassembly. During casting, the fit between the pier and the beam will not be affected, and the bridge can be tested normally, further reducing the bridge construction period and improving construction efficiency.

[0032] When the rotating mechanism rotates, the continuous jacks drive the pulling blocks to move, and the pulling blocks simultaneously drive several sets of second mating blocks and second fixed seats to move. The second fixed seats drive the beam to rotate, causing the second mating blocks to slide on the first mating blocks. Through the cooperation of the first and second mating blocks, the beam can rotate and descend simultaneously until it moves to the designated position. The rotating mechanism has an ingenious structure that can rotate only the beam and can be disassembled and reused. When the bridge is in use, the quality of rotating the bridge is the same as that of rotating the bridge using traditional methods. Attached Figure Description

[0044] When the two groups of beam bodies 3 are installed and closed, gaps are formed, and the first sealing block 10 and the second sealing block 11 are fixedly connected at the gaps.

[0045] In specific implementation:

[0046] A construction method of a bridge rotating installation closure structure:

[0047] S1: The two groups of continuous jacks 601 are started through the control console 603, the steel strands on the continuous jacks 601 drive the pull block 909 to move, the pull block 909 drives the first matching block 902 to move on the second matching block 905, drives the beam body 3 to rotate and descend around the rotating assembly, and the beam body 3 is rotated to a specified position.

[0048] S2: The beam body 3 is in contact with the top end of the bridge vibration reduction support 8, a plurality of groups of bridge vibration reduction supports 8 are fixedly connected with the beam body 3 through bolts, the first sealing block 10 and the second sealing block 11 are fixed at the gaps formed when the two groups of beam bodies 3 are abutted and closed, and the two groups of beam bodies 3 are fixed.

[0049] S3: The bolts between the second fixing seat 906 and the beam body 3 are removed, the connection between the rotating mechanism and the beam body 3 is disconnected, the continuous jacks 601 are started again, the bridge vibration reduction supports support the beam body 3, the rotating mechanism does not bear the gravity from the beam body 3, then the bolts connecting the first fixing seat 901 and the pier 1 are removed, the rotating mechanism is disassembled and moved, and the bridge vibration reduction supports 8 in the circular hole of the first matching block 902 are fixedly connected with the beam body 3 through bolts.

[0050] S4: The continuous jacks 601, the hydraulic pump station 602 and the control console 603 are removed, and then the temporary platform 2 is removed, and the abutment and closure are completed.

[0051] When the rotating mechanism rotates, the second matching block 905 is fixedly connected with the second fixed seat 906, and the second matching block 905 is fixedly connected with the beam body 3 through bolts, so that when the continuous jack 601 drives the pulling block 909 to move, the pulling block 909 simultaneously drives a plurality of groups of second matching blocks 905 and second fixed seats 906 to move, the second fixed seat 906 drives the beam body 3 to rotate, and the second matching block 905 moves on the first matching block 902; the plane of the second matching block 905 slides on the plane of the first matching block 902, the inclined surface of the first matching block 902 is separated from the inclined block of the second matching block 905, when the plane of the first matching block 902 is separated from the plane of the second matching block 905, the inclined surface of the first matching block 902 is in contact with the inclined block of the second matching block 905, the second matching block 905 slides on the first matching block 902 along the inclined surface, until the plane of the second matching block 905 is in contact with the plane of the first matching block 902, and the rotating mechanism repeats the above steps, so that the beam body 3 can be rotated to a specified position. When the plane of the second matching block 905 slides on the plane of the first matching block 902, the rotating mechanism and the beam body 3 are mainly driven by the continuous jack 601 to rotate, and when the second matching block 905 slides on the first matching block 902 along the inclined surface, the beam body 3 mainly slides on the rotating mechanism by the gravity of the beam body 3 itself, and the continuous jack 601 also plays a certain traction role; after the rotation of the beam body 3 is completed, the rotating mechanism only needs to be disassembled, and does not need to be cast in the pier 1, so that the construction period of the bridge is reduced, and the efficiency of building the bridge is improved; the rotating mechanism is detachable and can be repeatedly used.

[0052] When the beam body 3 is used, the weight of the beam body 3 is generally light, and the continuous jack 601 can drive the beam body 3 to rotate, but when the weight of the beam body 3 is large, a layer of polytetrafluoroethylene material can be laid between the first matching block 902 and the second matching block 905 to reduce the friction between the first matching block 902 and the second matching block 905, and whether two groups of driving assemblies need to be added can also be judged according to the height of the ladder of the first matching block 902 and the second matching block 905 and the inclination of the slope, the two groups of driving assemblies are opposite to the motion directions of the previous two groups of driving assemblies, and are used for playing a traction role when the beam body slides downward due to the gravity of the beam body, preventing the sliding speed from being too fast and causing the position of the beam body to deviate when the beam body moves; the first matching block 902 and the second matching block 905 in the rotating mechanism are worn out when used, and need to be checked before each use.

[0053] Embodiment two:

[0054] The difference from the embodiment one is that: without disassembling the rotating mechanism, first, separate the first connecting block 15 from the second connecting block 16, then fix the bridge damping support 8 in the round hole of the first matching block 902 with the beam body 3 by using bolts, then rotate the mechanism around to build a wooden template, and pour the rotating mechanism, when pouring, because the first connecting block 15 is disassembled, the structure inside the rotating assembly is exposed, which is convenient for workers to pour the rotating mechanism, so that the concrete can flow to any place inside the rotating mechanism, at the same time, try to avoid the concrete flowing into the round hole of the first matching block 902, so as to affect the normal work of the bridge damping support; only need to wait until the concrete hardens, then remove the wooden template; when pouring the rotating mechanism, the first matching plate 4 and the second matching plate 5 can be fixed at the gap generated when the two groups of beam bodies 3 are abutted.

[0055] The above is only the embodiment of the present application, and the well-known specific structure and characteristics in the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should be considered as the protection scope of the present application, which will not affect the effect and practicability of the present application.
