Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anal canal auxiliary device, and in particular to a fixing structure and method for installing a berthing member. BACKGROUND

[0002] According to the high-pile wharf structure, the berthing member is arranged at the front of the wharf. Most of the existing berthing member installation methods adopt the resting method, the resting support beam is designed simultaneously with the wharf pile cap support system, and the eccentric moment is balanced by using the counter-pressure method before the installation of the berthing member: the berthing member is rested on the overhanging end of the support beam, the support beam must be placed on the adjacent two pile foundations, and the upper and lower positions of the contact part between the support beam and the pile foundation are limited to form a fixed counter-pressure to prevent the end of the support beam from being raised after the berthing member is rested and fixed.

[0003] During the construction of the pile foundation, a construction platform in the range of the pile cap and the berthing member needs to be installed, and a first auxiliary pile also needs to be arranged. After the construction of the pile foundation is completed, the pile cap, the construction platform in the range of the berthing member, and the first auxiliary pile are removed together.

[0004] The installation of the berthing member by using the resting method is mostly suitable for the installation of the berthing member with a small lateral spacing of the pile foundation and a light weight of the berthing member itself. Because the wharf is arranged at sea, for the berthing member with a large lateral spacing of the pile foundation, the counter-pressure cannot be arranged; for the berthing member with a heavy weight of the berthing member itself, the end of the support beam cannot be raised, so that the stability of the support system during the installation of the berthing member and the cast-in-place construction of the pile cap cannot be ensured. SUMMARY

[0005] The present application aims to solve the problems that for the berthing member with a large lateral spacing of the pile foundation, the counter-pressure cannot be arranged; for the berthing member with a heavy weight of the berthing member itself, the end of the support beam cannot be raised, so that the stability of the support system during the installation of the berthing member and the cast-in-place construction of the pile cap cannot be ensured.

[0006] To solve the above problems, the present application provides a fixing structure for installing a berthing member, comprising:
